A lift apparatus has a frame with open sides and a web assembly slidably retained along the sides which extends from one end of the frame to the other. While the web assembly is retracted, the frame moves to pass around a mobility-impaired individual and rest against the surface supporting the individual. The web assembly is then extended to move underneath or behind the individual, providing lifting support. The frame is configurable for orientations ranging continuously between horizontal and upright sitting. The web assembly has an upper web contacting the individual, a lower web contacting the support surface, a strength layer carrying the individual's weight, and a roller nose bar assembly which is pulled to extend the web assembly. A hand-held power tool can drive the web assembly, adjustment of inclinations of the back and leg sections of the frame, and vertical motion of the lift arm.

A derailleur utilizes a 4-bar linkage, including a housing which acts as one bar of the 4-bar linkage. A hydraulic assembly located within the housing moves the housing relative to the mounting shaft in response to hydraulic pressure to define a chain guide operating path. The derailleur device may include a detent mechanism formed on one of the three other bars. In one embodiment, the 4-bar linkage includes an input shaft rotatably attached to the housing at a one end, and an output shaft rotatably attached to the housing at the other end, and the housing rotates around the first shaft in response to the actuation force. The hydraulic assembly may include a piston which moves within a cylindrical bore, with one of the three other bars of the 4-bar linkage being attached to the piston. The resulting hydraulic derailleur design is comparable to mechanical (cable-pull type) derailleurs in size and weight.

Compact hydraulically-operated derailleur shifting system for bicycles

A family of new bicycle shifting systems incorporate improved derailleur designs that are controlled by sealed hydraulic actuators. The shifting systems (i) a hydraulically-actuated, manually-powered front and rear derailleur shifting system, (ii) a hydraulically-actuated, power-assisted front and rear derailleur shifting system with manual control, and (iii) a hydraulically-actuated, power-assisted front and rear derailleur shifting system in which the shifting sequence for the rear derailleur is controlled automatically by pedal speed. Each of these shifting systems utilize a totally sealed, inclined linear shifting path. Environmental contaminants are prevented from entering any of the critical derailleur or control elements. The linear, inclined shifting path provides precise chain shifting, more uniform chain wrap on the rear bicycle drive sprockets, and lower chain and sprocket wear. Several different shifting control units are disclosed. An integrated shifting and braking module is also disclosed.

The invention provides the therapeutic compositions and a treatment method for alleviating IgE mediated allergis by administration of substance P together with a specific allergen are thereby reduced. The compositions and method are applicable to humans and animals such as dogs, cats and horses.

Composition for treating IgE mediated allergies comprising substance P

The present invention relates to a method and preparations for reducing IgE antibodies to allergens in allergic subjects wherein substance P and an allergen or fragments of allergens or haptens acting as allergens are administered together to the allergic subjects. The method can be used to treat humans and animals including dogs, cats, horses and subhuman primates.

Hymenoptera venoms for vaccine immunization of human subjects are prepared by copolymerizing the venom with albumin using glutaraldehyde as the polymerizing reagent. Sufficient albumin is used to produce water-soluble copolymers of high molecular weight. The resulting water-soluble copolymers of molecular weights above 200,000 daltons are separated from the residual reagents, insolubles, and lower molecular weight polymers or copolymers.

Albumin-solubilized hymenoptera venoms for vaccine use

The preparation of this invention comprises ragweed antigens polymerized with glutaraldehyde which are composed essentially of water-soluble polymers of molecular weights from 200,000 to 20,000,000.

A gold club designed for use in practicing the execution of a proper swing, the club being adapted to hold a golf ball until it is released at the bottom of the swing. The gripping elements are designed to hold the golf ball against the striking face of the club and avoid interference with the natural trajectory of the ball. The ball is released when the golfer pulls on a spring-biased cable extending from a first position located adjacent the golf club grip to a second position, where the cable coacts with the golf ball gripping elements.
