Abstract: The inventive concept is directed to shock free bulb socket that is inserted in an existing light bulb socket to forego any possible electric shock when there is no light bulb in the existing bulb socket and the electric switch happens to be in an “on” status. The insert socket is a housing that is placed over the existing socket and fastened thereto. The insert socket consists of a lower threaded segment that is threaded into the existing socket. There is an upper threaded segment that will receive the light bulb. When the light bulb is threaded into the upper segment it will encounter a plate there below and will cause the upper threaded segment to slide upwardly together with a bracket to which it is attached. There is a sliding hot prong and a sliding neutral prong which will make contact when the bracket moves upwardly and will convey electric current to the light bulb.
Abstract: An auxiliary power drive system is incorporated into a bicycle either as a retrofit or in initial construction. The power for the drive system is derived either from an electric motor or an internal combustion engine. The power developed by said motor or engine is delivered to the rear wheel of the bicycle by a flexible drive shaft which either drives a friction wheel operating on the tire of the rear wheel or to worm gear affixed to the rear wheel. The flexible drive shaft includes a friction clutch which discontinues the power of the drive shaft from driving the rear wheel when normal pedaling is resumed. The flexible drive shaft also includes a telescoping coupling to compensate any change in lengths of the drive shaft due to impacts on the rear wheel caused by the terrain the bicycle is riding on.
Abstract: A system for servicing a water well including a well pipe having a pump and a motor at a bottom thereof. The well head has a platform to support a winch thereon. Also supported on the platform is an upstanding mast having a return wheel at a top thereof. One end of a cable is attached to the winch and another end is attached to a top of the well pipe after having been trained over the return wheel at the top of the mast. Activating the motor on the winch will pull the well pipe from the deep well including the pump and the motor.
Abstract: There is a description of an apparatus that produces corrugated walls in a continuous manner. Prior to being fed into the apparatus there is a composite consisting of an outer layer of a woven or non-woven material having a layer of a cementitious material thereon. Two composites are combined in the apparatus with a layer of polyurethane there between. The apparatus has opposing molding tracts therein through which the composites are fed. The opposing molding tracts have a multiple of inflatable pockets thereon. The spaces between the pockets form the corrugations into which the composites are being pressed. At the end of the run of the molding tracts, the molded corrugated wall is then delivered to a roller run to be dried to its last extent.
Abstract: A demountable, wind-resistant sun shade canopy for shading childrens' play areas or other actively used areas. The canopy cover, being removably secured over a metal support structure, is comprised of vertical columns upon which are mounted at the upper end thereof respectively, uniquely configured bracket fittings, each bracket fitting providing secure mounting for a cantilever beam extending outwardly toward the perimeter of the area to be shaded, and providing secure mounting for a hip beam extending upward and toward the inner portion of the area to be shaded.
Abstract: Epoxy probe cards are modified by mounting passive and/or active electronic components on the insulating surface of the probe card and connecting those components to the probe wires with short, electrically conductive lines that are formed on the probe card surface by printed circuit techniques. Ordinary wire probes may be interspersed with coaxial probes and probes with electrically conducting tips bonded to electrically insulating shanks. An auxiliary printed circuit board containing additional electronic components may be included to accommodate especially sensitive test points. The resulting probe structure is intended to extend the frequency range of the well-developed epoxy probe card technology while retaining its ruggedness and low cost features.
Abstract: The invention is directed to a protective rod system which is installed on the bottom of a boat by a hinge assembly which installation is about midway between the length of the boat. The protective rod system is designed to prevent manatees from being hit by the propeller of the boat to avoid injury. The protective rod system is so designed that when in a deployed system, the protection to the manatee is in place or a retracted system whereby the bottom of the boat is substantially clear of any obstruction so that the boat can navigate in shallow waters. The protective rod system extends below and beyond the rotation circle of the propeller when activated or deployed.
Abstract: The invention pertains to an electric wire fish implement including fiberglass sections which are connected to each other to form an elongated implement which is used to introduce wires into inaccessible locations. The fiberglass sections are connected to each other by way of connectors at each end of the sections. The connectors are made of brass so that they can easily be attached to the fiberglass section ends by impressed dimples. one of the connectors is a female connector having a cylindrical recess therein. The other connector is made up in the same way but a threaded male stud is inserted therein and securely and permanently fastened therein. The male stud has a shore hardness considerably greater than the sleeve material. This stud helps to avoid breakage of the connection between the fiberglass sections when subjected to extreme or undesirable bends. There is also disclosed a way of quickly connecting or disconnecting various sections to or from each other, respectively.
Abstract: The invention pertains to an ironing system including an ironing board and an iron operated on a top surface of the ironing board in the process of ironing a fabric on the ironing board. Included in the system is a device for keeping the electric cord of the electric iron a distance above the ironing board so that the electric cord cannot interfere with a fabric that already has been ironed. The device also keeps the electric cord of the iron from being singed or burned by the hot sole of the iron. The device includes a tensioned coil spring through which the electric cord passes to the iron as it is kept in an elevated position. The coils of the tension coil spring are close and adjacent to each when the coil spring is in a rest position. A slight extension of the tension coil spring will induce a retracting force in the spring so that the electric cord will be withdrawn into the tension spring coil and away from the iron.
Abstract: A probe for testing integrated circuits at microwave frequencies employs a tapered coaxial transmission line to transform the impedance at the probe tips to the impedance of the test instruments. Mechanically resilient probe tip structures allow reliable probing of non-planar circuits and the elastic probe body allows large overprobing without damage to the test circuit. Novel insulator structures for the coaxial line allow easy and accurate assembly and high performance.
Abstract: A probe tip structure is disclosed which is obtained from a solid piece of material having a bore machined therein which extends from a first end where the probe tip is attached to a coaxial transmission line to a second end where contact points are machined therein. The inner conductor of the transmission line extends into the bore to the second end of the probe tip where another contact point is formed. All contact points are adapted to contact a device under test. A rigid insulating structure is placed within the bore of the probe tip to hold the inner conductor securely in a fixed position.
Abstract: The visual alignment aid for connecting the ball of the hitch on a towing vehicle to the socket on the tongue of the trailer is a device constructed of three components which are connected to each other by hinges. One of the components is a base component, a second one of the components has a convex mirror attached thereto and the third of the components has a means for attaching the device to the rear of a vehicle. All three components may assume an angulated position relative to each other and the vehicle to establish a correct line of vision between the driver and the ball and the socket. The three components can be arrested relative to each once a correct line of vision has been established. Color coding may be used on the arresting means to indicate the angulated positions. The same device could be used on a different type of vehicle and once a correct line of vision has been established for that different vehicle, a different color would be used to indicate the rotational positions.
