Abstract: A surface mounted integrated (IC) device package or carrier is disclosed suitable for accommodating large terminal count IC devices in a small space. A carrier, preferably of plastic, is disclosed having notches or castillations in its sides. A first row of leads are positioned in the periphery of the package and a second row of leads are positioned in the notches, said notches formed a predetermined distance from the periphery of the package (e.g., 0.050"). Selected leads of the second row are alternated with said first row of leads. In the preferred embodiment, the first and second leads are separated by 0.025". Also in the preferred embodiment, the first and second row of leads extend over protuberances into depressions in the bottom of the package. Each of the depressions is separated by ribs from the other depressions such that the ends of the leads are disposed in the depressions and are prevented from substantial movement, thereby preventing contact with adjacent leads.

Abstract: A torque command proportional to accelerator position is provided at low speeds with a transition to a torque command dependent on accelerator pedal position that varies to provide constant horsepower at high speeds. The transition occurs between constant torque command and torque command providing constant power at decreasingly lower speeds with decreasing accelerator pedal position. The torque command provides the control input to a traction motor for an electric vehicle.

Abstract: A wind electric generator employs a freewheeling clutch and an induction generator having several synchronous speeds. By selecting the synchronous speed as a function of the ambient wind speed, the generator can be made to operate more efficiently and without overloading. The freewheeling clutch which connects the generator to the wind turbine prevents the generator from acting as a motor when connected to a power grid, and wasting energy in turning the wind turbine.

Abstract: In a developer station for an electrophotographic printing or copying machine, there is provided apparatus which affords effective intermixing of carrier and toner particles in the developer mix and which enables the developer mix to be removed from the station prior to replacement in an automatic and simplified fashion. Transport and developer rollers are mounted in the station for conducting developer mix from a supply chamber to communication with a charge image carrier. A pair of rotary screws are disposed in the station on one side of the rollers with conveyance directions opposite to one another for conducting developer mix back and forth through the station enabling fresh toner to blend into the developer mix and maintaining uniform mixing of toner and carrier particles of the mix.

Abstract: A device for introducing an anti-microphony sponge into an air-cored coil for television channel selectors, comprising an axially displaceable hollow mandrel with an end portion which comprises two diametrically oppositely situated slots. Two blocking members can be introduced into the slots, after which cutting means are displaceable in a direction transversely of the axis of the mandrel. After the introduction of a length of spongy material into the mandrel, an air-cored coil is arranged on the end portion of the mandrel, after which the blocking members are moved into the slots so that the length of spongy material is clamped on both sides of the air-cored coil. Subsequently, the mandrel is withdrawn from the coil and the length of spongy material is cut in the zone between the blocking means and the withdrawn mandrel so that a piece of spongy material is left behind in the air-cored coil.

Abstract: The cable comprises one or more layers of insulated conductors disposed in circumferentially spaced relation. At least one layer is surrounded by a flexible shield formed from a inner layer of metallic foil bonded to a layer of flexible plastic. A ground conductor in the form of an uninsulated metal wire or a semi-conductive wire is disposed in the conductor layer directly adjacent to the shield. The ground conductor and the insulated conductors all have approximately the same outside diameter. This promotes intimate contact between the ground conductor and the shield.The cable is used in modular conjunction with a connector which holds the cable in pressurized engagement within a cable receiving opening. The pressure produced by the connector insures that intimate contact between the ground conductor and the shield will be maintained. The connector is designed such that the pressure applied to the cable can be varied.

Abstract: The disclosure is directed to an electrophotographic copying apparatus with variable magnification which is arranged to accurately register or align a leading edge of an electrostatic latent image with a leading edge of a copy paper sheet even when various copying magnifications are required, while synchronizing adjustments for the purpose are facilitated for an efficient copying operation.

Abstract: A control to automatically adjust the air bleed screw on a pneumatic dashpot to alter the return speed of a scanning carriage. At the start of the carriage flyback, an end of scan position signal is generated and a second signal is generated when the carriage has reached the home position. These two signals conveyed to control logic determine the time period of the scan flyback. The time period of scan flyback is compared to an acceptable window or range of flyback time periods. If the scan flyback time period is outside the range of acceptable time periods, an adjust drive signal is conveyed to an adjust solenoid. The activation of the solenoid causes the solenoid armature to move a ratchet wheel into engagement with the pneumatic dashpot air bleed screw.

Abstract: A technique and assembly is disclosed which allows more effective heat dissipation in a printed circuit assembly. A heatsink plate is etched using the artwork or masks used to form the conductive strips and terminals on a conventional printed circuit board. The heatsink plate is secured over at least a portion of the surface of the printed circuit board by an adhesive and the resulting heatsink assembly is mounted adjacent to a thermally conductive bracket.

The clamp configuration is such as to allow slidable movement between similarly shaped wedges which produces proper formation of the thermally conductive path during clamping.The Government has rights to this invention pursuant to contract No.
