The instrument tray has a bottom (preferably perforated) for holding other types of instruments for sterilization and access.

Abstract: The cautery instrument body has finger-operated valves for respective connection to sources of suction and irrigation. The valve plungers each have at least one O-ring which engages against a shoulder on the body when the valves are closed to cause positive shutoff when the valves are unactuated. The suction control valve has an adjustable stop to limit valve opening to control suction. The body has connection ports on each end so that it is reversible and has a clear polymer cannula attached in one of the ports for endoscopic utilization. The other port carries a cautery rod which can be extended out of the cannula. The suction and irrigation valves, the adjustable suction stop, and the cautery rod are all positioned so that they can be operated by the fingers of the hand which holds the body of the instrument.

Abstract: The water remediation and purification apparatus includes a cavitation nozzle which is operated with a throat size and pressure drop to incur cavitation in the water. The explosive and implosive bubble growth and collapse produces free radicals which interact with contaminants in the water to oxidize the contaminants. The cavitation process is enhanced by (1) a variable throat nozzle, (2) recycling the product back through the nozzle for further oxidation, and (3) programmable control feedback. Subsequent ultraviolet radiation from high energy lamps, ion exchange and/or degassifying treatment can be employed to produce water quality within acceptable levels.

Abstract: The irrigator aspirator instrument body has finger-operated valves for respective connection to sources of suction and irrigation. The body has connection ports on each end that it is reversible and has a clear polymer cannula attached in one of the ports for endoscopic utilization. The body is also transparent so that, during suction, complete aspiration can be observed. The other port carries a cautery rod which can be extended out of the cannula. The polymer cannula prevents capacitive charge coupling to the cannula.

Abstract: A trunk extends down through an opening in the truck's flat bed. A mounting frame is pivoted in the trunk and swings to an open position where the fifth wheel mounted thereon is exposed. Locks releaseably retain the frame in the open and in the closed positions.

Abstract: The javelin is a hand-thrown toy having a tubular fuselage. Mounted on the forward end of the fuselage are four canard planes, and mounted adjacent the rear of the fuselage are four tail planes. The forward surfaces and rear surfaces are each at a right angle and straight with respect to the fuselage to prevent spinning. The forward and rear surfaces are positioned at 45 degrees with respect to each other. The surfaces are sized as compared to fuselage length and weight so that the javelin flies level without spinning. A soft nose ring attached to the forward end of the fuselage prevents damaging impact.

Abstract: The cushion has a contoured base with a layer of resilient cushion foam thereover. The cushion foam is of uniform thickness over a substantial part of the base and is suitably covered. The shape is such that the buttocks of the seated person are clasped positioned rather than supported. A recess is provided under the ischia, under the trochanters, and beneath the sciatic nerves to limit the local pressure. In one configuration, these recesses may contain air bladders which are inflated by body motion against a back bladder in the cushion. In another embodiment, the various bladders may be sequentially pressurized to shift the bearing areas under the buttocks of the seated user in order to periodically lift the user for stimulating blood circulation.

Abstract: Redundant wall retractor is tubular and is obturated for insertion. It has a duct which terminates in an opening at the top of the anterior end and terminates with a tube fitting at the bottom at the posterior end. It is made of dielectric synthetic polymer composition material, preferably transparent to retract tissues during loop electrode excision procedures with the duct positioned for withdrawing smoke.

Abstract: A keysafe has tumblers which are set by a key-like programmer and has combination wheels which, when correctly set, have slots which receive the set tumblers. Thus, there is a unique combination for each programmer. In order to reset the combination wheels to their beginning, reference position, a slot is provided in each combination wheel, together with a lock bar which can enter the slot when the combination wheels are in the reference position. This lock bar is actuated to permit the programmer to be withdrawn.

Abstract: The electronic lock system is useful for a key safe where many different persons must have controlled, recorded access. Each user has a card key which is connected to one of a plurality of key safes to complete the system. The user inserts his personal identification number (PIN) into the card key in order to activate the card key. The card key is laid against a key safe so that an exchange of data takes place between key safe and card key to perform the security, access and control functions. The card key and key safe interact to exchange information so that the key safe may have memory of which card key is being used at which time, and vice versa. Updating of other memory functions can be accomplished. Validity is verified if a board number and a security level number in the card key relate correctly to their counterparts in the key safe and if the card identification (CID) number is not in the lock invalid CID number list. When valid, the key safe can be opened.

Abstract: The protective shield for a hypodermic syringe includes a tubular body which overlies the needle of the syringe when the shield is in the forward position. The protective shield has an opening therein to permit exposure of the needle when the shield is in the retracted position. A detent engages the syringe and the shield to limit relative motion therebetween and to releasably lock the shield in its end positions.

Abstract: An actuator tube slidably embraces the overflow tube on a toilet tank and has an actuator flange at the lower end thereof. An actuator sleeve slidably embraces the actuator tube with stops limiting the relative sliding distance. An actuator surface is also mounted on the sleeve so that, when the flapper valve at the bottom of the toilet tank is raised to release flush water, the float descends and with it descend the actuator tube and flange, as well as sleeve and actuating surface. The flange thrusts the flapper valve partway down, and the actuating surface sliding down the tube finally closes the flapper valve before all toilet tank water is released to thereby conserve water.

Abstract: The endometrial aspirator has a tubular sheath or body which serves to receive a histological biopsy sample. The tube is closed at the distal tip and has a sample curette opening directly behind the tip. A rod extends to the opening, and at the proximal user end, extends out of the tubular body. The rod fits closely within the tube or preferably has an enlarged piston at the sample curette opening end. The distal tip is smooth, rounded and closed for ease of insertion. The body and rod are made of flexible material which is sufficiently stiff to prevent kinking during insertion.

Abstract: The screw-holding screwdriver has a sleeve threadedly attached to its shank. A chuck on the end of the sleeve has a slot in the side to receive a screw head and shank. By screwing the sleeve up on the shank, the screwdriver bit engages the screw head and clamps the screw head in the chuck for driving the screw. When partially inserted, the sleeve is rotated on the shank to release the screw to permit removal of the chuck from the screw. In this way, the screw is firmly retained while driving.

Abstract: The recreational vehicle has a valve which is remotely controlled to permit remote draining of the drain water tank. The method of flushing the tank, including remote control of the drain valves is also included.

Abstract: Described is a cut-sheet lamination using a laminator for the single or double-sided application of a film cut onto a printed circuit board using heated overlay rollers located opposite to each other in a housing. The printed circuit board and the cut film are fed to the overlay rollers simultaneously in the overlay region. The printed circuit board is led in with input rollers, and the film is pulled off a supply reel and is guided over input rollers to the printed circuit board. A cutting fixture is provided within the region of the input rollers. The cutting fixture cuts the film corresponding to the length of the printed circuit board in accordance with a sensor scan. The cutting fixture is put onto a lever capable of swivel motion. The cutting fixture travels along with the film at the cutting of the film, and the lead-in rollers for the film in the region where the cutting occurs are constructed as suction rollers.

Abstract: A float has a bore which slidably embraces the overflow tube in a toilet tank. The float carries a valve actuator therebelow with structure which permits adjustment of the downward position of the valve actuator. The float and/or valve actuator may be non-round in order to fit closely adjacent the wall of the toilet tank. When the flapper valve at the bottom of the toilet tank is raised to release flush water, the float descends with lowering water leve and the actuator closes the flapper valve before all toilet tank water is released, to thereby conserve water.

Abstract: The preferred embodiment of the shielded counter-rotating spinner assembly for microparticalization of liquid consists of two opposed, coaxial, counter-rotating, conical, sharp-edged spinners whose edges are in close proximity and whose outer surfaces are in close proximity with non-rotating shields which extend to the edges of the spinners. The purpose of the shields is to greatly reduce the spinner induced air drafts so that, when liquids are applied to the inside surfaces of the spinners through the axes of the driving motors, the droplets produced on the edges of the spinners are injected into very low velocity air.
