Abstract: An illuminated golf club head defines a cavity and includes a top surface and a face for impacting a golf ball during a swing. A light is mounted at the top surface, and a power source for energizing the light is disposed within the cavity and electrically connected to the light. A switch is mounted within the cavity and electrically connected to the light and battery to form an electrical circuit. In an embodiment, the switch closes, completing the circuit and momentarily illuminating the light, upon impact of the face with a golf ball. In another embodiment, the switch closes to momentarily illuminate the light upon impact of a golf ball at approximately the center of the face.

Abstract: A signalling device which is mountable on a rural route mailbox comprises a housing which encloses a light fluorescing material and an activating element which extends exteriorly of the housing. The activating element is triggered by opening the mailbox door, which moves the light fluorescing material to an exteriorly observable position within the housing where it emits a visual signal to residents that mail has been received.

Abstract: An improved lamp switching circuit for switching on a second lamp circuit upon every alternate application of power to a first lamp circuit. A magnetic latching relay alternately connects and disconnects the second lamp circuit in parallel with the first whenever power to the circuit is switched off. The relay is powered by the discharge of one of two capacitors, which respectively operate a set circuit and a reset circuit of the latching relay. Only one of the capacitors is charged at any time. While power is applied to the lamp circuits, one capacitor is charged while the other is kept discharged, in preparation for operation of the latching relay. When power is switched off, a control circuit senses this condition and triggers a thyristor to discharge the capacitor through the corresponding relay coil after a short predetermined time delay. A low voltage regulated power supply is derived from the a.c.

Abstract: A recessed lamp reflector has an integrally formed trim ring and fluorescent tube receptacles on opposite sides of an upper portion of the reflector. Fluorescent tubes extend across and downward, in the reflector, crossing at a central point within an upper portion of the reflector. Ballasts are mounted on an upper surface of the reflector between lamp receptacles. A cover covers the ballast and receptacles and interconnections and rests on top of the reflector.

Abstract: An electromechanical switching device connects and disconnects a second lamp means from a first circuit powering a first lamp means upon alternate powerings of the first circuit. A mechanical device switches the switching means and an electrical circuit across the first circuit has a relay to control the mechanical device.

Abstract: Power is controlled in a first circuit by a conventional off/on swtich. The power is used by a first device or group of devices connected to the first circuit. A second circuit has a second power-using device or group of devices. The second circuit is connected to the first circuit via an alternate action switch. Upon alternate energizations of the first circuit, power is supplied to the second circuit.

Abstract: Three embodiments for a holder for film, papers, canvas, sheets and the like, are disclosed. Each of the embodiments presented utilizes gravity in some fashion for the holding function. The invention generally comprises a recessed horizontal groove located upon a vertical planar surface which is covered by the holding assembly. The holding assembly comprises a vertical planar cover, the bottom edge of which participates in the holding. An object to be held is slipped between the bottom edge and the vertical planar surface and extended into the groove. Whereupon gravity means holds the object in a hanging fashion.

Abstract: A second lamp is connected to power terminals upon each alternate switching off of a first lamp so that, upon each alternate switching on of the first lamp, the second lamp is illuminated. A magnetic latching relay switches the second lamp into and out of the circuit. The relay is powered by the discharge of one of two capacitors. One capacitor powers a set circuit of the latching relay, and another capacitor powers a reset circuit. Only one of the capacitors is charged at any one time. While power is applied to the power terminals to illuminate the first light, one capacitor is held discharged while the other capacitor is charged in preparation for powering the latching relay. The discharge of the charged capacitor through the latching relay is controlled electronically by a triac having a control terminal which is brought to control voltage by a fourth capacitor after a third capacitor has been discharged over a predetermined short time.

Abstract: One end of an elongated flexible strap is connected to a screw base. The strap extends downward through a central opening in a cover and in a reflector. After the screw base is threaded into a socket, a gripper is pushed upward along the flexible strap, drawing the reflector up and a trim ring tight against the ceiling which surrounds the recessed fixture.

Abstract: One end of an elongated flexible strap is connected to a screw base. The strap extends downward through a central opening in a cover and in a reflector. After the screw base is threaded into a socket, a friction ring is pushed upward along the flexible strap, drawing the reflector up and a trim ring tight against the ceiling which surrounds the recessed fixture. The friction ring holds the lamp and reflector upward on the strap, without stretching the strap and without pulling downward on the screw base with a force substantially greater than a weight of the reflector and trim ring. While the friction ring holds the lamp on the strap, a gripper is moved into position beneath the friction ring to permanently support the friction ring. The strap is then clipped below the gripper.

Abstract: Ceiling lights have recessed cans with sockets mounted centrally on a resilient, usually cantilevered, support. A lamp with an integrally connected reflector and external trim ring are connected to the socket. The resilient support pulls the trim ring up against an area of the ceiling surrounding the recessed can, causing the trim ring to act as a self-leveling device for the lamp, while functioning in the manner as a suitable trim for covering the unsightly hole in the ceiling which accommodates the recessed can or fixture. This arrangement allows the near-maximum use of the diametrical width of the opening provided by the recessed fixture as a means of projecting more usable light downward.

Abstract: A powerhead mounting bracket is connected to a diver's breathing tank support. A cord connected to the receiver has a plug with a projection for loosely fitting in an axial bore of the powerhead. The plug is placed in the axial bore and the powerhead shaft is placed between the flanges on the receiver. The sling at the other end of the powerhead is stretched, forcing the powerhead tight against the plug, and the stretched spring is hooked into slots in the receiver. The stretched sling holds the shaft of the powerhead against the base of the receiver and holds the powerhead longitudinally against the plug. When required for use, the powerhead shaft is grasped near the firing end and is pushed in a direction towards the sling, further stretching the sling. When the plug drops out of the axial bore, the shaft is pulled outward from the receiver, allowing the sling to become untensioned, whereupon the sling drops out of the slot in the receiver.

Abstract: A 30-30 casing has sharpened rings formed in its enlarged base. Powder is packed in the casing, and it is sealed by inserting a primer portion, which is a 38 caliber pistol shell with a primer, in the open end of the packed casing and compressing the edge of the casing in the base area of the primer portion.Radial extensions on the casing hold the cartridge centered in a barrel spaced from a firing pin.The primer is ignited by hitting the sharpened rings against an underwater object and thus driving the cartridge and primer rearward against a fixed firing pin. The casing rockets forward out of the barrel, leaving the primer piece and smashing into the underwater object while the powder burns.
