Abstract: Golf practice apparatus is described in which a tethered ball is suspended below a support portion. This may be a right-angled stake or a vertical wood portion on a flat wooden base portion. Two electrical contact members are mounted above the golf ball so that when the golf ball is struck by a player, if the ball is hit squarely it will strike one of the contact members so that it makes contact with the other member. An electrical circuit is thus completed to activate a buzzer or a visual indication. If the ball is not hit squarely, then no indication is given.

Abstract: Apparatus and method for preparing fragments from tire casings in which an umbrelal type tire casing support is provided and an electric motor is utilized to rotate the tire casings so that a cutter can be utilized to convert the tire casing into fragment portions, the cutter being mounted for slidable movement towards and away from the tire casing.

Abstract: An apparatus and method for testing a shock absorber system when in place in a vehicle's wheel suspension assembly includes a plate member which is moved up and down to cause a wheel of a vehicle thereon to move up and down. The plate member is moved by operation of a motor to permit visible and audible examination. The test is continued beyond the point at which an inefficient shock absorber would exhibit visible and audible wheel bounce and rotation.

Abstract: A puzzle game or toy is disclosed comprising two spherical shells made of hard plastic or metal material and having over their surface a multiplicity of circular holes cut therein in a random pattern, the holes being of equal diameter with the exception of one hole having a slightly larger diameter. The second spherical shell has an inner diameter slightly larger than the diameter of the first spherical shell and mounted over the first shell such that the two shells are freely rotatable relative to each other. A spherical ball of metal or plastic is positioned inside the two spherical shells and is of a diameter such that it will pass through the two large holes but none of the other holes.

Abstract: A railroad switch, snow deflecting apparatus is described in which air is fed through conduits to primary nozzles for directing air along the rails and towards the switch points to a position adjacent the apex of the switch. Secondary nozzles are spaced from the primary nozzles and behind the switch points so as to direct air along and between movable rails of the railway switch, and in the same direction as air from the primary nozzles to maintain the railway switch operationally free of snow.

Abstract: A plug or poppet valve is positioned in relation to an opening for controlling flow through the opening, with a flange positioned over the side opening and having a portion extending into the interior of the housing towards the plug or poppet, said flange and its extended portion having a circular cross-section opening therethrough, said opening having an interior pre-determined pitch thread over a lower portion of its length.

Abstract: A control switch system for a railway switch heater with an environment probe near the switch and controlling switching on and off of the switch heater in a predetermined mode.

Abstract: A liquid conductivity measuring circuit with power-save features is described for use with a four electrode conductivity cell having two potential electrodes and two current electrodes positioned in the cell in spaced relation in a particular sequence with a first operational amplifier having its output connected and its inputs connected via an isolating capacitor and a buffer amplifier and a voltage setting resistance to a source of square-wave voltage, a second operational amplifier having its inputs connected to ground and via an isolating capacitor and its output connected to a reference resistance such as to control the current through the reference resistor to maintain one electrode at a constant potential, readout means being adapted to measure, on initiation of a single or small number of square-wave voltage cycles in a period short enough that no significant change of polarization of the potential electrodes can occur, the voltage between the positive and the negative half cycles or the change from z

Abstract: An ash remover having a cover movably secured to a main body. The cover of the ash remover is movable between an open and a closed position by means of a handle connected to the cover and protruding through the top of the main body remote from the cover.

Abstract: There is described a method and an apparatus for depositing oxide, such as zinc oxide, on a substrate by R.F. magnetron sputtering. The oxide deposit is "switched" from a non-conducting to a highly conducting material by a second discharge caused by a voltage applied to a screen grid immediately in front of the substrate, or is rendered conducting by a heating step.

Abstract: In the art of motor fuel carburetion where conventional carburetors are employed to mix and prepare the fuel/air mixture for introduction into the combustion chamber of internal combustion engines, and particularly where gasoline is used as fuel, the liquid fuel is sucked, or aspirated out of the provided discharge opening by the current of intake air as it flows past this opening, thereby presumably mixing and preparing the fuel/air charge.In this invention the method of mixing liquid fuel with air employs a liquid fuel delivery spray valve which is so located as to spray liquid fuel upon an electrically heated metal plate which instantly converts the fuel from its liquid state into vapor form; a water delivery spray valve which is so located in similar fashion as the fuel delivery valve described above, to moderate the explosive violence of high octane fuel in the combustion chamber of internal combustion engines; and an electrically heated porous screen to atomize the fuel/air/steam mixture charge.

Abstract: Apparatus for determining the wet bulb globe temperature (WBGT) index of the surroundings constructed from a copper globe having a blackened exterior surface and provided with a fabric cover, which may entirely surround the globe or may be in strips or strands extending over the surface of the globe, with a source of water to maintain the fabric cover at least partially wet. A temperature sensing device, which may conveniently be a glass thermometer, as its sensing portion located at the center of the globe whereby a measurement of the wet bulb globe index of the surroundings can be obtained.

Abstract: An anemometer includng a transistor in a transistor circuit with suitable voltages applied thereto and a semiconductor diode connected through resistors across the transistor. An output voltage is obtained, representative of the velocity of the wind incident on the anemometer, by taking the difference between the forward voltage drop across the base-emitter junction of the transistor and the voltage drop across the semiconductor diode.
