Abstract: A bar and circular display or scale indicator utilizing a matrix of miniature incandescent lamps which individually illuminate closely stacked light transmitting segments forming closely spaced dot positions spaced along the length of the bar. The incandescent lamps are staggered throughout the length of the display with the light transmitting segments (fiber optics) directing light from the lamp source toward the center of the display, to present emitted light in a well defined line to which provide a linear or circular solid state display. The dot positions can be illuminated in any number of ways individually, sequentially or otherwise, depending on the selected mode of operation.

Abstract: This invention relates to a method and flashing light safety device for cyclists' helmets which provides for a full 360.degree. elevated identification and protective warning to all surrounding drivers of vehicles. The use of the device will reduce accidents by pin-pointing the location of a cyclist in a stream of traffic or in intersecting lanes of traffic and thereby protect and enhance the safety of the cyclist using the device and the safety of those in vehicles in the surrounding traffic as well as pedestrians. The device is easily detachable for storage or carrying when not in use.

Abstract: A candle holder for candles formed from glass containers having wax and a wick therein. The candle is placed on a base which is relatively wide to provide stability. A cover is placed over the candle which partially covers the top opening of the candle. The cover is formed from a ring having a chimney extending upward from the inner diameter of the ring and a conical flange extending downward and outward from the outer diameter of the ring. The chimney has a plurality of holes spaced around its base. A pair of holding rods connect the cover to the base so that the candle is held between the cover and base to form a semi-rigid stable assembly.The cover, which may be used separately from the base, functions to prevent air currents over the top of the candle from causing the flame to flicker and smoke the inside of the glass container. The cover also keeps heat contained in the candle to melt the wax evenly across its surface.

Abstract: There is provided an improved lamp bulb guard having a circular tubular body portion, an inwardly flared portion and a circular tubular neck portion. Circumferentially spaced ventilating towers are provided. Each tower has a top portion, a front wall portion, and side wall portions. Vertically extending slots are provided, and each slot is protected by a baffle located radially inwardly thereof.

Abstract: A line-actuated fishing rod light includes an electrically conductive bracket, a battery therein, a threaded-base, bulb, and a spring wire trigger arm coiled to provide a socket for the bulb and extending beyond the socket to form a trigger finger. A fishing line is wrapped around the finger and, upon a fish strike, pulls the arm and socket toward a battery terminal. The bulb lights on contact of its terminal with the battery, through the circuit provided by the battery's rear terminal, a rear wall of the bracket, the bracket, the spring wire arm, the coil socket, and the bulb base. The line disengages from the trigger arm upon playing the fish, so that the light does not interfere with the line during such time. Also, the bulb can be rotated into and out of the coil socket to adjust the light's sensitivity to differing forces exerted on the line.

Abstract: An improved light adapted to be connected to a wheel of, e.g., a bicycle. In preferred form, the light is fixed to the wheel in a manner that orients the light's battery on an axis positioned substantially radially of the wheel, and that orients the light's battery radially inward of the light's bulb relative to the wheel's axis. A switch spring is provided in the light's housing that normally biases the battery out of electrical contact with the bulb when the wheel is not rotating, i.e., when the bicycle is not in use, but which permits the battery to be biased into electrical contact with the bulb in response to centrifugal force when the wheel is rotating, i.e., when the bicycle is in use. Thus, the light turns off automatically when the bicycle is not being ridden, and turns on automatically in response to centrifugal force when the bicycle is being ridden, when the light is mounted on a bicycle's wheel.

Abstract: A hand grenade is provided with a fuze comprising: a firing means, means luding two centrifugally-operated elements movably carried by the grenade housing for arming the firing means, means including an inertia member rotatable relative to the housing and a torsion spring between the inertia member and the housing for spinning the housing to operate the arming elements, and manually-held safety means for preventing arming until the grenade is thrown. Two disclosed embodiments have different arming and firing means with substantially the same spinning means.

Abstract: A novel shotgun wad is disclosed for use in a practice cartridge which includes a conventional tubular casing having a closed end and an open opposite end, the wad having a first cup portion facing a detonable primer charge at the closed end of the casing, and having a second cup portion facing the open end of the casing and defining a rounded aerodynamic flight end. Upon detonation of the primer charge, the wad is projected outwardly from the casing with the rounded flight end thereof facilitating a truer flight trajectory than obtainable without the rounded end.

Abstract: A signaling device to be launched underwater having a fuze body and a protile containing pyrotechnic compositions. The pyrotechnic compositions are ignited by an electrical squib which is detonated by voltage from a sea water battery which is sealed from sea water until a valve opens to permit entry of water into the fuze. An open circuit is provided between the battery and leads of the squib and, in addition, the squib leads are shorted. The opening of a valve to permit entry of sea water into the fuze causes the short to be removed and closes the circuit between the battery and the squib.

Abstract: A ball-and-socket, thrust nozzle for rockets has a movable member retained by a stationary member attachable to a rocket. The movable member includes a venturi throat and an expansion cone for the propulsive gases. At least one of the nozzle members has a spherical surface concentric about the center of rotation of the movable member. The other member bears against this spherical surface via a bearing seal in the form of a thin, narrow ring of lubricous material. The bearing seal is located in a position to support the axial blow-out load imposed by the propulsive gases. It is made of fibers of lubricous material, filled with a solid, lubricous resin; and it is bonded to a nozzle member either with the filler resin or with some other bonding agent. The side of the bearing seal that is bonded to the nozzle member may be reinforced with fibers having high tensile strength, woven into the lubricous fibers, or with a thin sheet of metal.
