Abstract: Disclosed is a receptacle having protective flaps that can prevent inadvertent insertion of alien objects into the slots of the receptacle. The receptacle having protective flaps can be made without the use of a separating plate as in the prior art so that it is cost-effective in manufacture and easy in assembly. The receptacle having protective flaps comprises a top cover having slots and a base for mounting the top cover thereon. The base has an integrally formed rib provided with paired notches to form a supporting piece therebetween. The protective flap is composed of a female frame and a male frame in which the female frame is provided with a sliding rail on lengthwise sides and the sliding rail is inset in the paired notches on the base and supported by the supporting piece so as to support the protective flap securely on the rib. An elastic piece is coupled to the protective flap for restoring the female frame and the male frame back to a closed condition when a plug is removed.

Abstract: A one-piece disposable syringe system is disclosed including a conventional syringe having a glass barrel that is prefilled with a measured dose of pharmaceutical and a syringe support and disposal jacket that is adapted to hold the syringe in an injection mode to facilitate the administration of an injection of the pharmaceutical from the barrel and surround the syringe in a disposal mode to form a compact package and thereby facilitate the safe handling and disposal of the syringe while avoiding an accidental needle stick and the possible spread of contagious disease. The syringe support and disposal jacket has lower and upper body members that are rotatably connected together by an integral living hinge.

Abstract: A lap tray is disclosed for carrying food such as that available from a take-out or fast food restaurant. The lap tray has particular application for use by an individual wishing to consume the food carried on the tray while riding as a passenger in a motor vehicle that is subjected to the usual road turbulence. The lap tray includes a pair of food serving compartments, each of which is surrounded by a raised lip to prevent food carried thereon from falling off the tray. A raised annular rim surrounds a hole formed through the tray in which a drinking cup is received so as to retain the cup in an upright configuration and thereby prevent the cup from tipping and spilling its contents. A pair of legs depends from the tray at opposite sides thereof to extend downwardly along the legs of the user so as to stabilize the tray against lateral displacement when the user is seated and the tray is laid across the user's lap.

Abstract: A compact, single-use stylus applicator is disclosed having a dry medication (e.g. a dehydrated topical astringent disinfectant that is adapted to treat acne and has been reduced to crystalline form by lyophilization) stored in a first chamber. A liquid diluent is stored in a second chamber. Fluid communication between the first and second chambers is blocked by a barrier. By compressing the second chamber, a corresponding hydraulic pressure is generated in the diluent which defeats the fluid blocking integrity of the barrier. Accordingly, the diluent in the second chamber is introduced under pressure to the dry medication in the first chamber to rehydrate and activate the acne medication. The reconstituted multi-constituent liquid medication is absorbed by a stylus-shaped swab so as to be applied directly to a tissue area as a topical treatment for acne or other skin disorders.

Abstract: An exercise device for use at home or in a gym by which a user can simulate climbing a ladder. First and second carriage tubes are slidable axially and reciprocally over respective first and second carriage guide rails that extend in spaced, parallel alignment between top and bottom frame members. The first and second carriage rails are interlinked by first and second drive cables and a series of cable pulleys so that the carriage rails move in opposite directions relative to one another in response to successive pushing and pulling forces applied by the user to hand grips and foot pedals connected to each of the carriage tubes. A hydraulic control system is provided to permit the user to selectively adjust the minimum force which must be applied to the hand grips and/or the foot pedals to cause the carriage tubes to slide along the guide rails.

Abstract: The exercise device provides a continuous loop of rope which is slowly fed downwardly from the greater extent of a davit-like housing, and through an open space in which the climber will perform the climbing exercise. The rope then continues through a friction pulley configuration driven by a variable speed gear motor, and then upwardly through the davit-like housing to again travel through the open space. The speed of the motor can be controlled in a feed-forward manner where the user sets the speed, as in one training configuration where the speed of the rope is to be exceeded by the climber, or where the progress of the climber movement may be determined by sensors which determine how close to a pre-determined height the climber has progressed.

Abstract: A golf bag and accessory carrier encompasses both an apparatus and method which serves the utility of a golfer both in carrying his golf bag, carrying his accessories, providing a water resistant carrying compartment, a basket type storage area, a self righting liquid refreshment carrier and a golf ball holder. These structures are enabled while still fully enabling a folding function, to enable the golf bag cart to be conveniently carried and stowed in the trunk or back seat of a car. The golf bag cart and accessory carrier provides a carriage and utility area wider than the golf bag being carried, both for stability and enhanced convenience.

Abstract: A flashing light housing that is adapted to be removably attached to the rear (i.e. heel) of any shoe, such as, for example, a sneaker, sport shoe, training shoe, or the like, without requiring factory alterations to the shoe. A manually accessible light control switch is operable by the wearer to selectively control the energization of a flashing light source that is carried at the interior of the housing. An attachment hook extends from the housing to fit over the top of and around the heel of the shoe, whereby the housing will be suspended from the heel. A resilient attachment band is connected to and extends outwardly and in opposite directions from the flashing light housing. The attachment band is adapted to be fastened to the sole of the shoe at each of a first side and an opposite side thereof, whereby to hold the housing against the heel. By virtue of the foregoing, the flashing light housing is characterized by a large viewing area that is easily visible to on-lookers.

Abstract: The jockey wheel, intended to be incorporated in the derailleur of a bicycle, permits limited lateral sliding movement of its outer ring gear relative to a central bushing, but requires a rolling bearing between the outer ring gear and the central bushing to rotate by fixing the ring gear to the outer race of the rolling bearing and the bushing to the inner race of the rolling bearing. In one construction, bushings between the inner race and shaft carrying the jockey wheel are keyed to one another to permit only lateral sliding movement. In another construction, the inner race of the rolling bearing is eccentrically shaped to interfit with the bushing, thereby permitting only lateral sliding movement between the eccentrically shaped inner race and bearing but requiring the inner race to rotate with the bushing.

Abstract: A low cost, relatively inexpensive and highly reliable tuned resonant circuit and method for prolonging the life of storage batteries of the type that contain a liquid electrolyte and are exposed to extensive periods of non-use. The resonant circuit is powered from a commercially available AC voltage source that is connected through a capacitor and a step down transformer to the input of a full wave diode rectification bridge. The output of the bridge rectifier is connected across the power terminals of the storage battery so as to supply a steady pulsating DC voltage thereto. By virtue of the foregoing, the battery electrolyte is excited so that the specific gravity thereof will be maintained at the original operating level of the electrolyte in a fully charged storage battery.

Abstract: A miniature, adjustable beam flashlight having a switch control nut that is rotatable in first and opposite directions around the body of the flashlight for controlling a switch assembly in order to energize a lightbulb and adjust the light beam produced thereby. The switch assembly is interconnected with the switch control nut so as to move in first and opposite longitudinally extending directions through the body of the flashlight to complete or open an electrical conduction path between a battery supply and the lightbulb when the nut is rotated in the first or opposite directions around the body. The lightbulb is coupled to the switch assembly and adapted to move therewith in the first and opposite longitudinally extending directions so that the lightbulb is axially advanced relative to the body when the electrical circuit path is opened or retracted when the circuit path is completed.
