A medicament vial safety cap which may be formed integrally at the time of manufacture of the medicament vial or added as an accessory to an existing conventional medicament vial allows an equalization of pressure to occur within a chamber adjacent to the stopper of the vial so that aerosolization of medicaments does not occur as a hypodermic needle is inserted or withdrawn from the vial. A hydrop...

A ski boot carrier comprises a double loop structure defined by a cord forming a first loop for looping through the buckles of a pair of adjacent ski boots, and a strap forming a second loop for looping over the arm of a skier for carrying the boots, leaving the hand of the arm free to grasp or carry other articles and the like.

A safety binding for a ski includes a jaw for holding the sole of a ski boot, the jaw being movable at least transversely with respect to the axis of the ski. The jaw is held in its normal position by an elastic member which returns it into its normal position after transverse movement. The jaw is associated with a pedal positioned under the end of the sole of the ski boot. This pedal includes a s...

An intraocular lens is adapted to be implanted within an eye adjacent the iris of the eye in either the anterior or posterior position or inside the lens capsule.

The fixation device provides supportive engagement with the eye structure in either the anterior or posterior position or...

An improved shrimp peeling, deveining and blanching process that is effective in removing the entire vein from the shrimp and that ensures that the entire exterior surface of the shrimp undergoes a desired color change. The vein is removed by making a longitudinal cut into the backside of only a few intermediate body segments and by pulling on the exposed portion of the vein, to remove that portio...

Preparing a flexible, polyurethane foam: (a) placing a polyol polyurethane foam-forming reaction mixture in a reaction zone and allowing the mixture to rise, thereby forming a partially cured cellular material, (b) applying a compressive force to the partially cured cellular material after the elapsing of a period of time after completion of the rise to thereby reduce the volume of the partially c...

At least one measuring wheel rolls freely against the floor under the vehicle, or two such wheels are journalled at different points on the vehicle for measuring off distances rolled. A computing unit and steering mechanism pivot said steer...

The filtering apparatus comprises at least one filtering material pleated in fanfold formation and arranged between the inflow or upstream side and the outflow or downstream side. Each pleat open toward the inflow or upstream side possesses a rounded base. The radius of the rounded base is in the range of 0.05 to 0.3 times the pleat depth. Each pleat open toward the outflow or downstream side term...

Flame resistant polyurethane foams are prepared by impregnating an open-cell polyurethane foam with a mixture of a carboxyl-containing polychloroprene latex, a zinc salt of a polymetaboric acid and optionally aluminium hydroxide.

This invention concerns the manufacture of a layer of elastomeric material to form part of a pneumatic tyre. A cylindrical layer of elastomeric material is formed by winding unvulcanised unreinforced elastomeric strip along a mandrel. An unrubberized cord may then be wound over the elastomeric layer to form a reinforced ply. The layer or ply can be transferred from the mandrel to a tyre carcass bu...

A differential assembly for a motorized vehicle and method of construction are disclosed, the assembly including a lock ring secured around each of a pair of differential shafts for providing a spring lock permitting each shaft and road wheel to turn with a differential housing when driven by a ring gear, the lock ring structure and method of construction evenly distribute the acceleration torque ...

A surgical laser backstop instrument comprising a rod, a backstop pivotally mounted to one end of the rod, and a backstop adjustment mechanism mounted to the other end of the rod. The backstop is comprised of a non-reflective material. The backstop adjustment mechanism controls the movement of the backstop. The backstop is a flat section of titanium-coated material and is movable between a positio...

Oxymethylene polymer bonded articles, such as multilayer laminates, are disclosed. Such articles are prepared by bonding together at least two articles shaped or molded from crystalline oxymethylene homo-, co- and terpolymers using, as an adhesive, a low Tg copolymer of trioxane and 1,3-dioxolane which have a dioxolane content greater than 65 mol percent and less than about 75 mol percent and an I...

This invention is directed to a novel translucent polymerized panel which can be used as is or be foamed or reinforced with glass fibre or other types of fibre, or reinforcing materials. These panels have good light transmitting, weathering and insulating qualities and do not yellow upon prolonged exposure to ultraviolet light. The invention is directed to a process of producing an acrylic product...

A method is disclosed for the preparation of ceramic materials or articles by the pyrolysis of mixtures of vinyl- or allyl-containing preceramic silazane polymers, mercapto compounds, and photoinitiators wherein the mixtures are rendered infusible prior to pyrolysis by ultraviolet (UV) irradiation. This method is especially suited for the preparation of ceramic fibers.

A composition is provided comprising an epoxy resin, a nitroparaffin and a sulfonic acid. The presence of the sulfonic acid retards gellation of nitroparaffin-containing epoxy resin compositions intended for use in water-dispersible coating formulations cured with modified polyamine resins.
