Abstract: The invention is a replaceable golf shoe cleat or spike 10 for use in place of a standard metal spike 4. Winter golf shoe spike 10 preferably has a main cleat body 11 molded from a durable plastic type material in single unitary fashion. A threaded stud 13 is formed on the upper surface of generally concavo-convex flange 12 and protrudes axially therefrom. A plurality of traction ribs 15 are formed on the bottom traction surface of concavo-convex flange 12. While the ribs 15 may be present in a variety of configurations, they are preferably triangular ridges arranged in a radial fashion emanating from the center of concavo-convex flange 12.
Abstract: Non-reusable syringe having a syringe body, a hypodermic needle and a slidable piston for drawing and discharging fluid through the needle. In one embodiment, the non-reusable syringe includes a movable engagement member. A first position of the movable engagement member permits initial withdrawal of the piston, allowing fluid to be drawn into the syringe. Initial withdrawal of the piston moves the movable engagement member into a second position. After the fluid has been substantially discharged, the second position of the movable engagement member captures the piston and prevents the piston from being withdrawn again. In another embodiment, the movable engagement member is mounted on, and movable with respect to, the piston. The non-reusable syringe can also include a releasable connection between the piston and the piston driver. Once the piston has been captured, a second attempt to use the syringe will separate the piston from the piston driver, further preventing reuse of the syringe.

Abstract: A linear electromechanical actuator has a spring-loaded plunger disposed in a housing. When a solenoid in the housing is energized, the armature of the solenoid moves linearly and, after some initial "lost" motion, engages and releases the latch mechanism holding the plunger in the housing. The spring associated with the plunger is then free to extend the plunger from the housing. The actuator can be designed so that it is highly immune from unintended actuation due to acceleration of the actuator. The condition of the actuator (e.g., fully cocked or released) can be monitored by switches disposed in the actuator. The actuator can also be constructed to allow manual release as an alternative to release by energization of the solenoid.
Abstract: A mechanical actuator assembly which automatically releases the load controlled by the actuator when the actuator jams or otherwise fails. The actuator assembly has two kinetic energy sources, the outputs of which are normally summed for application to the load. A monitoring device monitors the two kinetic energy outputs. When the relationship between those outputs deviates substantially from a predetermined relationship, the load is disconnected from the actuator assembly.
Abstract: An applicator for delivering an object, such as a menstrual tampon, to a cavity, such as the vaginal canal, which applicator is not much longer than the object when delivered to the user, is provided. The applicator is a unitary injection blow-molded device which includes a first tubular section housing the object, a second collapsible and extensible corrugated tubular section abutting the first section, and a third tubular section abutting the second section and serving primarily as a handle. An integral pusher member is formed in the interior of the applicator attached to the inner wall of the third section, and is biased to assume a position along the centerline of the applicator. The applicator is delivered to the user in a collapsed state, with the pusher alongside the object in the first section. The user extends the object by pulling on the first and third sections, withdrawing the pusher from the first section so that it aligns itself behind the center of the object.
Abstract: A surgical staple remover has two pivotally connected arms, each of which is made up of a proximal handle piece and a distal nose piece. All four pieces are held together by a single pivot pin, and the handle and nose pieces of each arm interfit with one another so that both pieces of each arm pivot as a unit about the pivot pin. The nose piece of a first arm includes two, small, laterally spaced members which can be slipped under the backspan of a surgical staple to be removed. The nose piece of the second arm includes a single member which is initially between and above the two laterally spaced members. When the arms are manually squeezed together, the single member bends the center of the staple backspan down between the laterally spaced members and pivots the legs of the staple out of the tissue.
Abstract: A unitary assembly of surgical fastener retainer members is disclosed. The assembly includes a plurality of retainer members, preferably of a resinous material, arranged in a surgically useful configuration and connected by flexible or frangible links preferably of the same material. The assembly facilitates handling of the retainer members and loading them into fastener applying apparatus.
