Abstract: A solar energy collector and tracker has at least one north-south oriented torsion tube supporting an array of flat rectangular solar panels. At least one pier, supported in the earth, has pivot member in which the torsion tube is journalled. A linear actuator has a body portion mounted on a footing separate from the pier footing and supported in the earth at a distance spaced from pier, and has a rod coupled to a torque arm on the torsion tube. The actuator can be horizontally or vertically oriented. The torsion tube is generally square cross section. The torsion tube may be formed of two or more sections joined end to end. In such case, one of the sections may have one end swaged to fit tightly into the end of a next successive section to form a tight, secure coupling between sections. The pivot member can have four plastic resin inserts within a cylindrical journal on respective sides of the square torsion tube.

Abstract: A device for relieving leg cramps, which is comprised of a shaft, a handle at a proximal end of the shaft, and a stirrup attaching to a distal end of the shaft. The device is comprised of rigid, lightweight, plastic tubing and is detachable and portable for the safety, comfort and convenience of the user. While lying in a supine position, e.g. in bed, a user experiencing a leg cramp (or charley horse) extends the affected leg, places the stirrup of the device over the toes so that the cushion covering the transverse bar bears against the sole of the foot. The user then pulls the handle proximally to pull the foot upwards and hyper-extend the cramped muscles until the cramp is relieved. Assistance of another person is rendered unnecessary.

Abstract: A vehicle sticker for monitoring a time-period associated with a motor vehicle, comprises an electronic timer, first and second indicator devices, and some mechanism for affixing the sticker to the vehicle. The timer is configured to time the time-period associated with the vehicle and to generate an "impending expiration" signal and an "expiration" signal. The first indicator device is coupled to the timer, and is configured to indicate an "impending expiration" or a "renewal" warning in response to the impending expiration signal. The second indicator device is also coupled to the timer, and is configured to indicate the expiration of the time-period in response to the expiration signal. The affixing mechanism must hold the sticker on the vehicle, in such a position that the impending expiration indication is directed to someone inside the vehicle and the expiration indication is directed to someone outside the vehicle.

Abstract: Wave curb for the cow stand of a diagonal or herringone milking parlor is formed of an elongated sheet metal strip. The side edges are each bent over about 180 degrees to form unitary beads on the side edges. The strip is bent in alternate curves in the longitudinal direction so as to form a succession of alternate arcuate bights, preferably with a wavelength of about 36 to 42 inches. Preferably, the strip is stainless steel or galvanized steel, and has a finished length of about 36 to 144 inches. The sheet metal workpiece is inserted into a wave curb bending apparatus which simultaneously forms a first pair of opposite arcuate bights. Then the workpiece is moved longitudinally in the wave curb bending apparatus; and a second pair of opposite arcuate bights is formed in the sheet metal workpiece.

Abstract: This invention relates to the provision of a paint mask in the form of a stick which is housed in a lip balm or stick deodorant type of dispenser. The invention provides for the supply of a paint mask in the form of a stick constructed for immediate and convenient use by application to the surface of glass or other base to be protected from inadvertent paint. Such an application is especially suited for painting window frames and mullions while prohibiting paint to affix itself to the glass. The invention provides for the direct application of a paint mask coating onto the material to be protected, which coating does not permit paint to adhere to the underlying surface. The present invention's ease and accuracy in application and absence of any required period for drying or setting-up overcomes the disadvantages present in spraying, squeezing, rolling and brushing liquid paint masks.

Abstract: Wood flooring panel is made of a plurality of parallel longitudinal wood slats situated side by side, with the slats being of the same length but staggered in their longitudinal positions. A tambour backing is adhesively secured to a back side of the slats to hold the slats together as a panel. The tambour backing is made of a material that is inextensible in the longitudinal and lateral directions, but flexible to permit bending at joints defined between said wood slats. There are clips or tabs affixed onto the back surfaces of the respective slats at the front ends. These extend about a half-inch beyond the forward ends of the respective slats. The tambour can be secured with a hot melt adhesive. The clips can be formed of rectangles of fish paper. The clips prevent the flooring adhesive from coming between the front ends of the slats of one panel slats and the rear ends of the next panel slats. The clips also help align the ends of the corresponding slats or fingers of the two panels.

Abstract: A method of administering a Generally Accepted As Safe (GRAS) indium compound, preferably indium sulfate mixed with distilled water, comprises preferably spraying 1 to 27 mg of indium sulfate into the mouth on arising in the morning and without eating or drinking for at least 10 minutes thereafter.

Abstract: The present invention is a passive filter for controlling the return path loss in a communication system having a forward path and return path. The filter comprises first and second terminals, a passive filter network, and a compensation circuit. The passive filter network is coupled to the first and second terminals and to ground. The filter network has a first passband which passes signals in the forward path and a second passband which passes signals in the return path. The filter network includes a passive attenuator network which attenuates signals in the return path by a predetermined amount as the signals pass through the second passband. The compensation circuit is coupled to the passive filter network, and is configured to compensate for expected perturbations in the frequency response of the second passband of the filter network.

Abstract: A ceiling or overhead air conditioner unit is configured to fit into a standard space, e.g., two-foot by four-foot, in a dropped ceiling. The unit can be a self-contained air conditioning unit with HEPA filter, or an air conditioner attachment adapted to fit onto a blower and filter assembly. The positions of the condenser air intake and outlet can be field-selected at either the end, the top, or the side, e.g., using a movable plate. The evaporator return inlet can similarly be field-selected at the top, side, or end. The return bypass inlet can be field-selected at the side or top. The room air intake can be connected by a duct either to outside air or to an intake air grille in the ceiling. The air conditioning attachment unit that fits an existing or available ceiling mounted filter and blower assembly has its condenser section on one side of the unit, and its evaporator section at the other side, guiding conditioned air into a centrally situated cool air plenum.

Abstract: A tremolo locking device for an electric guitar or similar stringed instrument has a lower part that is fastened to the guitar body and an upper part that can be pivoted by use of the guitarist's fingers into or out of engagement with an edge of the tremolo base plate. The upper part can have a threaded barrel member into which a knurled screw is adjustable to establish a gap or recess that engages the base plate.
