New Wayne Helix(TM) Fuel Dispenser to be Featured
New Wayne Helix(TM) Fuel Dispenser to be Featured

AUSTIN, Texas, Jul 17, 2012 (BUSINESS WIRE) -- Wayne, A GE Energy Business and a global innovator of fuel dispensers and technologies, today announced that the new Wayne Helix(TM) fuel dispenser will be the official Fuel dispenser of BP s "Fuelling the Future" Showcase in London during the 2012 Olympic and Paralympic Games. BP is the Official Oil and Gas Partner of the London 2012 Games and will be providing advanced fuels for many of the fleet of over 5,000 vehicles. BP selected Wayne s Helix dispenser to highlight the advancements being made in the fuelling stations of tomorrow.

Wayne has been a strategic global supplier to BP for nearly 30 years, providing fuel dispenser and payment solutions to BP affiliates in the U.S., Europe, Turkey and South Africa. This strong relationship stretches back to include the Amoco and Arco brands prior to, during and after BP acquired those companies.

BP challenged Wayne to design and build a fuel dispenser that could showcase BP s future product aspirations from both a fuelling and payment perspective. The station of the future will likely see increasing levels of bio components blended into conventional fossil fuels such as petrol and diesel. As such, fuel suppliers will need dispensers that have been tested and certified to handle the rigour and demands of a wide range of biofuel blends and that also are safe, secure and easy to operate. Wayne developed the Helix fuel dispenser based on extensive research and feedback from distributors, retailers, technicians and motorists from around the world. Helix dispensers are built on a global platform for worldwide design recognition and a consistent reliable fuelling experience.

"Being selected by BP as the featured dispenser for its London 2012 biofuels showcase speaks to the commitment Wayne has made to elevate the standard for the modern fuelling experience," said Neil Thomas, Wayne global president. "We created this dispenser for an increasingly globalized world, with significant input from our customers and from motorists worldwide. It s a product line that will be the same for all Wayne customers in all regions."

The Helix fuel dispenser family is designed to meet the standards of both ATEX and UL, global regulatory governing bodies for safety. The new dispenser also delivers Wayne s industry-leading, state-of-the-art payment-security platform, which is certified to comply with both PCI and EMV(TM) payment-security standards. Additional features such as enhanced displays with high-contrast, ergonomic design as well as expanded branding and signage areas visible from multiple angles establish the Helix dispenser family as a new standard for the fuelling station of the future.

"Hammersmith is a showcase for `industry s firsts , and we have been delighted to work with our partner, Wayne, to continue this theme," said Stewart Bates, BP design manager Europe, ANZ, SA & Russia. "With the installation of the world s first Helix dispenser, designed and engineered to the needs of tomorrow s fuelling stations, we will continue to highlight what is possible." http://www.datianmachine.com/about.htm

スプロケット
スプロケット

バイクではチェーンがかかっている歯車の部分を指す。エンジン側とホイール側の二つのスプロケットがあり、ホイール側がリヤスプロケット(ドリブンスプロケット)、エンジン側がフロントスプロケット(ドライブスプロケット)と呼ばれる。 チェーン同様、常に過酷な状況下におかれているパーツであり、チェーンルーブを注さずに走り続けたり、たるんだチェーンで走っていると摩耗の度合いが激しい。もし、摩耗したスプロケットで走り続けているとチェーンが外れる恐れがあるばかりか、最悪チェーンが切れて重大な事故を引き起こすことも考えられる。チェーン給油の際はスプロケットの減り具合もチェック。また販売店でも定期的に点検してもらおう。また、摩耗したスプロケットのままチェーンのみを交換すると、せっかくの新品チェーンを傷めかねない。チェーン交換の際にはフロント/リヤスプロケットも同時に交換しよう。


スプロケット(sprocket)とは軸の回転をローラーチェーンに伝達したり、ローラーチェーンの回転を軸に伝達するための歯車のことである。チェーンホイールとも呼ばれる。身近な物ではオートバイ、自転車、無限軌道などの駆動伝達、写真や映画のフィルムの給送部品に広く用いられている。

Effects of introducing strengthening ribs
Effects of introducing strengthening ribs

Purpose – The purpose of this paper is to present experimental investigations on the structural behaviour of composite sandwich panels for civil engineering applications. The performance of two different core materials – rigid plastic polyurethane (PU) foam and polypropylene (PP) honeycomb – combined with glass fibre reinforced polymer (GFRP) skins, and the effect of using GFRP ribs along the longitudinal edges of the panels were investigated.

Design/methodology/approach – The experimental campaign first included flatwise tensile tests on the GFRP skins; edgewise and flatwise compressive tests; flatwise tensile tests on small-scale sandwich specimens; and shear tests on the core materials. Subsequently, flexural static and dynamic tests were carried out in full-scale sandwich panels (2.50×0.50×0.10?m3) in order to evaluate their service and failure behaviour. Linear elastic analytical and numerical models of the tested sandwich panels were developed in order to confirm the effects of varying the core material and of introducing GFRP ribs.

Findings – Tests confirmed the considerable influence of the core, namely of its stiffness and strength, on the performance of the unstrengthened panels; in addition, tests showed that the introduction of lateral reinforcements significantly increases the stiffness and strength of the panels, with the shear behaviour of strengthened panels being governed by the ribs. The unstrengthened panels collapsed due to core shear failure, while the strengthened panels failed due to face skin delamination followed by crushing of the skins. The models, validated with the experimental results, allowed simulating the serviceability behaviour of the sandwich panels with a good accuracy.

Originality/value – The present study confirmed that composite sandwich panels made of GFRP skins and PU rigid foam or PP honeycomb cores have significant potential for a wide range of structural applications, presenting significant stiffness and strength, particularly when strengthened with lateral GFRP ribs. http://www.szydjh.com/Eng_d268717383.htm

China nonwoven Fabric
China nonwoven Fabric

Usually people consider textile fabrics as the common categorization such as woven, knitted, braided or tufted constructions. They commonly abandon china nonwoven fabrics form the textile group. In the conventional fabric, the fibre is first made into yarns; on the other hand, china nonwovens are manufactured sheets or webs directionally or randomly orientated fibres, bonded through resistance, solidity or sticking together into a fabric.

The demands for fabrics have increased sharply. Conventional textiles are not able to meet the production cost and higher cost of upgradation along with demanding consumers in new fields of consumption. With better customization of characteristics into the fabric and appropriateness to certain end uses being advantages, china nonwovens have emerged rapidly as the fabrics of the future.

China nonwoven fabrics presents many advantages over conventional fabrics, the clearest benefit is cost savings. In recent couple of years the china nonwoven industry has emerged at a rapid speed, offering a huge range of products to several diversified fields. Conversely, china nonwoven fabrics hold some natural characteristics, which led them to be counted for non-usable in certain applications.

A REVIEW REPORT ON: COATING OF SOFT GELATIN CAPSULES
A REVIEW REPORT ON: COATING OF SOFT GELATIN CAPSULES

Highly developed soft capsules are currently being applied widely in the pharmaceutical, chemical, food and cosmetic industry. This is attributed to the features of softgels like desirable aesthetic properties and ‘swallowability’, safety enclosure, precise contents, and pleasing appearance. This has enabled their use as an effective delivery system for hydrophobic drugs, low melting-point drugs, easy-oxidized drugs, and a variety of health care oil. Since the introduction of Soft Capsule Making Machine in the 1970s, formulations have continually become more popular with rapid developments in recent years. This could be illustrated by emergency of a more than 560 sets of soft capsule making machine with transfer mode having a production rate of up to 60 billion pills/year (i.e.more than 3600 kinds of drugs) in the world. Up to now, there are more than 30 manufacturers producing more than 40 kinds of soft capsules by using over 60 sets of advanced machines. Softgels’ ability to enhance bioavailability not only makes them the preferred dosage form for new chemical entities with poor oral bioavailability, they can also be used for reformulation of existing drugs, with the purpose of life-cycle extension.

The softgel delivery system is a unitary package, formed with gelatin outer layers, which contain between them the active ingredients in solution, suspension or paste form. Hydrophobic drugs do not dissolve readily in water, gastric or intestinal fluid. When they are compounded in solid dosage forms, their dissolution rate is usually low and absorption varies resulting in poor bioavailability. Bioavailability of these drugs can be improved in the presence of fatty acids e.g. mono or diglycerides. Fatty acids do solubilize hydrophobic drugs in the gut and enable more rapid absorption. The softgel delivers drugs in solution and yet offers solid dosage form. These hydrophobic drugs are dissolved in a hydrophilic solvent, which, when crushed or chewed, releases the drug immediately to produce a solution of the drug in gastric juice ready for absorption from the gastrointestinal tract into the blood stream. This results in rapid onset of desired therapeutic effects6. For example, Ibuprofen soft gel gives rise to a shorter time to peak plasma concentration and greater peak plasma concentration compared to a marketed tablet formulation. Cyclosporine does give therapeutic blood levels which are not achievable from tablet form. Similarly oral hypoglycemic glipizide in softgel is also known to have better bioavailability results compared with tablet form. Softgel delivery systems can also incorporate phospholipids or polymers or natural gums to entrap the drug active in the gelatin layer with an outer coating to give desired delayed/control release effects.

The designs for a specific soft gelatin capsule formulation involve appropriate selection of the shell and fill composition. This is followed by optimization of the two to allow for efficient production of a chemically and physically stable product with the desired biopharmaceutical properties. The shell of a soft gelatin capsule is composed of gelatin, a plasticizer or a combination of plasticizers and water. In addition, it may contain preservatives, coloring and opacifying agents, flavorings and sweeteners, possibly sugars to impart chewable characteristics to the shell, gastroresistant substances and in special cases even active compounds8.The formulation of the fill is individually developed to fulfill the requirements for optimum therapeutic action.This entails optimizing the chemical stability of the active compound to improve bioavailability. Emphasis is also put on efficient and safe filling process in order to achieve a physically stable capsule product. http://www.jiangnan.co/
