Granted: 2003-06-10
Abstract: An air bag actuated brake cylinder assembly for a railway vehicle braking system is provided which comprises a cylindrical casing engaged with the railway vehicle braking system including a hollow piston assembly having a piston rod assembly attached thereto and mounted for longitudinal movement within the cylindrical casing. An air bag actuator is engageable with the hollow piston assembly and an inner surface of the cylindrical casing for moving the piston and piston rod in an outward direction upon actuation thereof to initiate a braking sequence of the railway vehicle braking system. The air bag actuated brake cylinder assembly of the present invention allows for improved control of the movement of the brake cylinder piston and consequently improved control of the brake shoe forces which is especially desirable during light load conditions. Also, the air bag actuated brake cylinder of the invention is capable of accommodating piston bail and/or misalignment without leaking air. Additionally the air bag actuated brake cylinder assembly of the invention requires less maintenance to maintain the air tightness of the system and allows for the simple replacement of an inflatable bag into the cylinder should an air leak in the actuator occur. Currently used brake cylinder assemblies may be retrofitted with the air bag actuator of the invention.

Abstract: To identify the need for replacement of stranded synthetic fiber ropes (1), preferably ropes of aramide fiber, a torsionally neutral rope construction of load-bearing fiber strands (2, 3, 4, 5) is obtained by having at least two layers of strands (7, 14) laid together in opposite directions so that the torsions in the layers of strands (7, 14) due to their lay compensate each other. If the layers of strands (7, 14) become weakened by unequal amounts due to wear or external influences, when the rope (1) is under load and running operationally it begins to twist about its longitudinal axis (20). The twisting of the rope (1) can be made visible by means of various measures.      In one embodiment a mark (11) along the length of the rope indicates twisting of the rope and thereby serves to provide visual identification of the need for its replacement.

Abstract: A carrier sheet has a detachable totally laminatable card integrally formed therewith. A clear plastic film patch having two thin plastic film sheets laminated together by an adhesive therebetween and a release coating, is glued to the back of the sheet in a card area. The inner one of the plastic film sheets has the release coating on its inner surface in contact with the adhesive secured to an inner surface of the outer one of the plastic film sheets. A card is delineated by a die-cut made in the front surface of the carrier sheet and extending to the adhesive between the film sheets. A perforation cut is made in the outer one of the plastic film sheets and aligned with the die-cut. A photograph or fingerprint is applied in a designated area on the outer face of the card. When the die-cut card is peeled off the front surface of the carrier sheet, it creates a card window exposing the adhesive and by positioning the outer face of the card into the card window and pressing on the card, and then pushing the card through the form, the front face of the card becomes laminated with the outer plastic film sheet. The inner surface of the card is laminated by the inner film sheet when the patch is applied and the card is die-cut. Accordingly, there is formed a personalized card which is plastic film laminated on both faces.

Title: Regulating access to digital content
Inventor: PATTERSON PATRICK E
IPC: G06Q20/12

Granted: 2008-10-07
Abstract: Digital content such as text, video, and music are stored as part of a compressed and encrypted data file, or object, at a client computer, such as a personal home computer. The content is inaccessible to a user until a payment or use authorization occurs. Payment or use authorization occurs via a real-time, transparent authorization process whereby the user enters account or use data at the client computer, the account or use data is transmitted to a payment server computer, the account or use data is preprocessed at the payment server computer and if payment information is required and is present, the payment information is transmitted to a payment authorization center. The payment authorization center approves or rejects the payment transaction, and bills the corresponding account. The authorization center then transmits an authorization signal to the payment server computer indicating whether the transaction was approved and if not, which information was deficient. In response, the payment server computer transmits a token to the client computer, and if the token indicates approval, an installation process is initiated at the client computer whereby the object is activated and locked to the particular client computer. The object can be reopened and reused at any time on that particular computer. If the object is transmitted or copied to a different computer, the required payment or use information must again be tendered for access to the content.

Title: Hemostatic agent, method and carrier for applying a blood clotting agent
Inventor: REDING JAMES W
IPC: A61K31/14
Filed: 2001-04-30
Granted: 2008-01-29
Abstract: A hemostatic agent, method and carrier for arresting the flow of blood and other protein containing body fluids flowing from an open wound and for promoting wound healing. A broad aspect is directed to a substantially anhydrous admixture of an oxyacid salt and a hydrophilic proton donor which will hydrate in the presence of blood and body fluid to produce cations to promote blood clotting. The preferred oxyacid salts are alkali and alkaline earth salts of transition metals and halogen oxyacids with oxidizing capabilities sufficient to accelerate blood clotting. Another embodiment of the invention includes the compound containing an oxysalt plus a hydrophilic polymer such as carboxy methylcellulose, polyvinyl, alcohol, an alginate, and all soluble gums. Still another embodiment of the invention includes the compound formed of an oxyacid salt in combination with a hydrophilic proton donor and a solid desiccant which further accelerates blood coagulation reaction rates. The cation exchange material or an admixture of an alkali metal oxyacid salt plus acidic inorganic salt produces a scab or protective coating over the wound for protection and enhanced healing. Oxygen produced during the reaction substantially reduces the level of bacteria, virus and fungus at the wound. The resin is performance-enhanced for greater fluid uptake and more rapid coagulation.
