Abstract: A rake head attachment to be removably attached to a handle, such as the shaft of a golf club, and which is constructed so that it may easily and quickly be coupled to the shaft of the golf club. This is achieved by dropping the shaft between two spaced and parallel pieces mounted on the rake head, by turning the shaft into slots in the two pieces, and then by drawing the shaft through aligned holes at the inner ends of the slots until the hosel is firmly engaged by the pieces. The slots in the pieces are shaped and positioned such that the rake head is firmly held on the shaft of the golf club without any tendency for the rake head to turn or otherwise move with respect to the shaft.

Abstract: An instrument for inserting a deformable intraocular lens into the eye, and which is constructed so that the deformable lens is grasped in its undeformed state by two jaws mounted on the end of a shaft which are forced together as the shaft is drawn into a tube, the deformed lens being held in position by the confinement of the jaws by the tube. The tips of the jaws and the deformed lens are inserted through an incision into the eye using the walls of the incision to help compress the jaws and the lens. The lens is then completely inserted into the eye by a plunger mounted coaxially within the shaft and returns to its original undeformed state after it has been so inserted.

Abstract: A keep-alive circuit for a regulated switched-type power supply for forcing the power supply to generate power pulses under conditions where the apparent output voltage level is such as to cause the regulator circuit normally to reduce the power pulses effectively to zero. The keep-alive circuitry responds to the absence of the power pulses over a predetermined time interval to modify the regulating circuit so that the regulating circuit responds to a different output voltage level to force the power supply to generate a power pulse under the aforesaid conditions. The action is made cyclic and the power supply is thereby caused to generate a series of low frequency power pulses indicating that it is still alive.

Abstract: An electrically energized vaporizing unit for medications, room deodorizers, room scenting compounds, room insecticides, and the like, which is simple and inexpensive in its construction and which is compact in size. The vaporizing unit includes a housing having a central slot for holding a compressed paper fiber pad which is impregnated with the substance to be vaporized. The pad is heated by a pair of electrical heating elements which are located in the housing and positioned on opposite sides of the slot for maximum vaporizing efficiency of the pad. The housing may also contain paraffin wax. The melting point of the wax is selected to correspond to the vaporizing temperature of the particular substance in the pad. The vaporizing unit is provided with an electric plug which may be directly plugged into an electric receptacle to energize the PTC heating elements, and it does not require a switch or protective thermostat.

Abstract: A child's liquid drink container in the form of a canteen which is equipped with a drinking straw. The canteen has a dome-shaped rotatable cover with a hole in one side. The cover may be rotated to a first angular position in which an internal closure member closes the hole with the straw retracted into the cover. The cover may also be rotated to a second angular position in which the closure member moves away from the hole and in which the straw is caused to project out through the hole. This enables one to drink the liquid contained in the canteen quickly and easily and without the need to remove the cover.

Abstract: A gas-tight end fitting for a tube, such as the type used in aircraft. The fitting has an internal annular groove extending partially into the fitting which forms an annular flange or beam, and the face of the beam and of the remaining portion of the fitting has a concave configuration of a single predetermined radius.

Abstract: A pouring nozzle for a soft drink, milk or liquor bottle, carton, or the like, which has a feature in that when the container is in an upright position, the nozzle automatically closes to seal off the container. The nozzle includes an internal ball which floats on liquid trapped in the nozzle to close and seal the nozzle when the container is upright. However, the ball is forced into a cavity in the nozzle when the container is tilted over to permit liquid to flow freely from the container through the nozzle.

Abstract: An intraocular lens of the Fresnel type which is constructed so that the Fresnel surface itself is sealed by the posterior capsule surface to overcome the problems encountered in prior intraocular lenses in which the Fresnel surface is exposed. The Fresnel lens surface is recessed entirely within the posterior surface of the intraocular lens in an open recess to form a space between the posterior face and posterior capsule surface when the intraocular lens is positioned in the eye. The sealed space facilitates the use of a YAG laser for a posterior capsulotomy should posterior capsule opacification occur.

Abstract: A self-activated gaff which responds to contact of a trigger bar with an object to cause a pair of tongs to close and embrace the object and to lock around the object until released. The gaff uses a piston-like member and a pair of constant force means to couple the piston-like member to the tongs.

Abstract: A system for monitoring human locomotor activities over long periods of time by recording acceleration (G.sub.z) of the subject during such time periods, and by then converting acceleration to foot/ground forces (F.sub.Z) of the particular subject by a previously calibrated conversion table relating to that particular subject.

Abstract: A solid state electronic controller for electrically-operated water sprinkler valves in an irrigation system. The controller is constructed to control a number of different water sprinkler valves in each of a number of different watering zones, for successive time intervals at one or more preset time periods during each day of the week. The controller includes a liquid crystal display which exhibits instruction words and numbers to facilitate the programming of the controller, for monitoring the operation of the controller, and also for exhibiting malfunctions in the system.

Abstract: A rechargeable flashlight assembly intended particularly for use in automobiles, aircraft, boats and other automotive vehicles, which serves to assure that an operable flashlight will be available at all times. The assembly comprises a receptacle adapted to be mounted on the dashboard, or other suitable location in the vehicle, and which houses an electrical charging unit; and a flashlight containing rechargeable batteries which is constructed to be inserted into the receptacle when not in use to establish contact with the charging units so that its battieries will be maintained in a charged state.

Abstract: An interstitial sub-floor formed of concrete contained in a prefabricated formwork composed of a plurality of rigid plastic eggcrate-type modules positioned adjacent to one another and bonded to one another.

Abstract: A thread, such as a floss, impregnated with a hypo-allergenic, anti-bacterial astringent for cleansing and conditioning pierced ear lobes.

Abstract: A waterproof housing which is intended to be buried in the ground, and which serves to protect the splices of buried electrical cables such as are used, for example, in irrigation control systems. The housing is formed of two identical half-sections configured to snap together around the crimped splice of two or more cables. Each half-section is pre-filled with a plastic insulating gel which becomes adhesively attached to the crimping sleeve of the splice and which forms a perimeter seal around the splice. Troughs are provided at one end of each section as a means of entry for wires to be spliced. Thin frangible dams are molded onto the outer ends of the troughs to maintain the gel in the half-sections during filling, and which are crushed by the cables when the two half-sections are pressed together.
