Abstract: A fast forward cartridge tape player includes the conventional cartridge receiving cavity and cylindrical capstan. The capstan is rotatably driven about its vertically positioned longitudinal axis by a motor actuated flywheel, and it is located to forcibly engage the cartridge pressure roller on cartridge insertion into the cavity. Crescents, having a concave face, a convex face, and a vertical dimension are positioned to rotate about the capstan. The concave face encircles greater than 180.degree. of the capstan circumference while revealing a substantial arc on the capstan surface. The convex face is of predetermined curvature providing a desired fast forward speed/normal speed ratio. The vertical dimension of each crescent is fixed to allow each crescent access to the pressure roller. In the normal mode play a means decouples capstan rotation from the crescents and aligns the crescents to allow the pressure roller access to the revealed capstan surface.

Abstract: A reversible continuous loop cartridge includes a conventional front accessible pressure roller drive. A first pulley is affixed to, and rotatable with the roller. A second pulley is coupled through a one way clutch to the cartridge hub. An O ring interlocks the two pulleys, whose diameters are in a predetermined ratio. When driven in the forward direction the roller, and pulley rotate but the clutch decouples the hub whereby the tape is driven in the well known manner. When reversely driven the clutch engages such that the roller, pulleys, and hub rotate. The hub drive assures proper reverse operation of the continuous loop tape.A fast forward cartridge tape player includes the conventional cartridge receiving cavity and cylindrical capstan. The capstan is rotatably driven about its vertically positioned longitudinal axis by a motor actuated flywheel, and it is located to forcibly engage the cartridge pressure roller on cartridge insertion into the cavity.

Abstract: A rotor for the high voltage distribution system of an internal combustion engine, the contact member of the rotor being movable relative to the rotor shaft for a desired advance-retard characteristic. The rotor itself does not move relative to the rotor shaft. The device is for use with electronic ignition systems and one function is to replace the mechanical advance provided in conventional breaker point type distributors by the centrifugal weights which rotate the entire cam and rotor assembly. A range of characteristics responsive to engine velocity and/or acceleration is provided for within the basic design.

Abstract: A manually operable lever feeds a selected fuel to the engine. A cam having lobes made of a magnetic material is affixed to a shaft driven off the engine. Each of a plurality of reluctance pickups is predeterminedly positioned to form a magnetic circuit with the lobes at given engine angular positions. A mechanically operable switch feeds a selected pickup output to a triggerable ignition system. Linkage connects the switch to the manual lever.

Abstract: Multiple resistance elements are mounted in parallel pairs around the inside curved wall of the assembly housing. Multiple cylindrical contacts in a planetary arrangement are rotated by a friction drive surface mounted on the control shaft. Each cylindrical contact rolls on one pair of resistance elements. The cylindrical contacts, by being movable shunts between the parallel strips, provide ganged multiple potentiometer or rheostat capability. No terminal is connected to any moving part. The diameter of the drive surface and the diameter of the cylindrical contacts determine the possible number of resistance elements per assembly. Shaft rotation for full range variation, thus vernier capability, is determined by the ratio of the drive surface diameter to the inside diameter of the housing.

Abstract: A semicircular thrust arm has an anvil at one end and a rotatably mounted idler wheel at the other. The arm is pivotally mounted at its central portion in a predetermined tape player locale. A pushbutton activated lever mounts on the player and is aligned to forcibly engage the anvil on pushbutton depression. Anvil engagement causes the arm to rotate and forces the idler wheel into the cartridge pressure roller-player capstan interface whereby capstan rotation couples through the idler to the pressure roller. The idler thus reverses the rotatable drive to the pressure roller thereby reversing tape direction.The rate of tape drive is controlled by selecting a particular ratio of idler wheel diameter to pressure roller diameter. The pressure roller consists of two cylinders fixed to rotate on a common shaft. The first cylinder is of selected diameter for normal tape speeds and the second cylinder, which is engaged by the idler, has a smaller diameter for increased speeds.

Abstract: Apparatus for switching a silicon controlled rectifier (SCR) into an off state and maintaining it there is disclosed. The apparatus uses a diode and an inductor in series with the cathode of the SCR. The voltage developed across the diode is negatively applied across the gate to cathode electrodes to maintain the SCR in an off condition. The diode voltage is applied to the SCR electrodes by a switching transistor. An alternator regulator system which uses the SCR control apparatus is also disclosed.
