Abstract: A pickup truck cap having bendable plastic side panels having a bottom side located along a respective riser installed on each pickup truck cargo bed side wall. The side panels are each engaged by a curved respective guide located adjacent each end of each side panel to conform each side panel to curvature of an associated guide. An upper side of each side panel is received beneath a rectangular top assembly included in the cap. Either of side panels are movable upwardly to raise the bottom side thereof up from a respective riser to create an access opening beneath a raised side panel along each side of the cap. A pair of movable side panels can also be arranged to close off access through a cover installed on the cargo bed of a pickup truck.

Abstract: A base support assembly for the cargo bed of a pickup truck mounted on the truck including a pair of parallel side by side slotted side guide rails installed on a respective cargo bed sidewall and a pair of U-shaped end support frames each having a pair of legs pivotally mounted to each of the opposite ends of the side guide rails so as to able to be swung up to an erect position or lowered down position after the base support assembly is installed on the pickup truck cargo bed side walls. An elongated slotted top guide rail may be connected at either end to the top of each end support frame. The end frames can be collapsed into a support for a rigid tonneau cover by lowering the end support frames.

Abstract: A cap for the cargo bed of a pickup truck assembled on the truck including a base support frame comprised of a pair of parallel side by side slotted side guide rails and a hoop support frame pivotally mounted to each of the opposite ends of the side guide rails so as to able to be swung up to an erect position after the base support frame is installed on the pickup truck cargo bed side walls. An elongated slotted top guide rail is connected at either end to the top of each hoop support frame. Flexible side panels are inserted in respective slots on the side guide rails and top guide rail assuming a convex shape to cover the cargo bed. End panels close off either end of the cap, a rear panel may be hinged to the rear hoop support frame to be operable and may be transparent to provide a window. The hoop support frames and end panels may be adjustable in width to be matched to the cargo bed width.

Abstract: A machine that forms parallel snow skiing tracks, a container (48) mounted thereon, ejects water throught calibrated jets (16) by force from a small air pump (32) powered by a twelve volt utility battery (30), the water freezes on contact with the snow and renders the tracks glazed with ice, which greatly enhances the ability of the skies to glide in the tracks.

Abstract: A truck rack (10) for a bed (14) of a pickup truck (12) in which a pair of opposing front supports (18) and a pair of opposing rear supports (20) attach at respective lower ends to the bed of the pickup truck, with the rear supports (18) each having a leading edge and a trailing edge defined by opposing surfaces that taper from a transverse spacing to the respective leading and trailing edges and the front supports (20) each have a trailing edge defined by opposing surfaces that taper from a transverse spacing to the trailing edge of the front support, with a pair of opposing side rails (22) that attach to respective front and rear supports, and interconnect by forward, intermediate, and rear transverse members (28) extending between and attached to the opposing side rails.

Abstract: In a power source system, a method for providing color mixing in a high intensity discharge (HID) lamp comprises the steps of providing a swept frequency signal having a sweeping frequency ranging between a first lower frequency value and a second higher frequency value, within a specified period. An amplitude modulation signal is also provided having an adjustable frequency value and an adjustable modulation index. As a result the sweeping frequency signal is modulated by said amplitude modulation signal. The frequency of the amplitude modulation signal is adjusted until a maximum lamp voltage is detected. Thereafter, the system operates with a modulating frequency that yields the maximum lamp voltage so as to substantially eliminate color segregation in the lamp.

Abstract: A high pressure gas discharge lamp and the method of making same utilizing integrated circuit fabrication techniques. The lamp is manufactured from heat and pressure resistant planar substrates in which cavities are etched, by integrated circuit manufacturing techniques, so as to provide a cavity forming the gas discharge tube. Electrodes are deposited in the cavity. The cavity is filled with gas discharge materials such as mercury vapor, sodium vapor or metal halide. The substrates are bonded together and channels may be etched in the substrate so as to provide a means for connection to the electrodes. Lamps having ignition enhancing and hot restrike features, as well as single-sided electrodes, are disclosed.

Abstract: An arc tube for an electrodeless metal halide discharge lamp has an arc chamber fabricated from a material selected from the group consisting of magnesia-doped polycrystalline alumina, silicon dioxide doped polycrystalline alumina and monocrystalline alumina. The arc chamber is tubular and has at least one end and has a given outside diameter. At least one end cap closes the at least one end of the arc chamber, the end cap being formed from magnesia-doped polycrystalline alumina and comprising a substantially cup-shaped member having an inside diameter which is sealed to the outside diameter of the arc chamber by a shrink-fit.

Abstract: This invention teaches a novel high pressure electric discharge lamp which has the desired properties of high efficacy, good color rendering, and a warm color temperature. These desired properties are attained by utilizing as fills the rare earth iodides in conjunction with calcium halides and, or sodium halides. Efficient visible emission from the rare earth atomic and molecular fragments in the discharge is combined with the red emission from calcium monohalide to provide an efficient, warm source.
