Title: Control mechanism for motor vehicles
IPC: B60K23/02
Filed: 1932-07-20
Abstract: 386,573. Controlling motor vehicles. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. July 20, 1932, No. 20516. Convention date, July 20, 1931. [Class 79 (v).] In a control system in which the accelerator pedal controls a clutch servo-motor, the accelerator pedal can be rotated in either direction from its neutral position to open the throttle, but in only one of these directions is the clutch servo-motor controlled. Thus, if the vehicle is coasting at high speed with the throttle closed and the clutch consequently disengaged, the accelerator can be operated in one direction to open the throttle and speed up the engine without engaging the clutch until the engine speed is approximately the same as that of the driven part of the clutch shaft ; after which the accelerator can be operated in the other direction and the clutch engaged without shock whilst the two parts of the clutch are rotating at the same speed. In the construction shown the accelerator pedal 46 is connected by a link 42 to a floating lever 56 connected at its ends by links 48, 50 to two arms 60, 62 freely pivoted on the shaft 75 of the throttle valve 68. The arms 60, 62 are normally held against stops 76, 78 by springs 72, 74, and are provided with curved arms 64, 66 adapted to actuate the valve 68 which is normally closed by a spring (not shown). If the pedal 46 is rotated in the usual clockwise direction the link 42 presses the arm 60 against its stop and the lever 56 turns about the pivot 52, so that the link 50 is pushed to rock the arm 62 and open the throttle valve by means of the arm 66. If the pedal is rotated counterclockwise the link 42 is in tension and pulls the arm 62 against its stop, so that the lever 56 turns about pivot 54 and the link 48 is pulled to rotate the arm 60 and open the throttle by means of the arm 64. Thus, the throttle is opened whichever way the pedal is rocked from the neutral position shown. The link 42 is connected by an arm 40, spring 80, and link 38 to a valve 20 adapted to connect a clutchoperating cylinder 12 either to the engine induction pipe 26 or to the atmosphere, to disengage or engage the clutch (not shown). When the pedal 46 is rotated clockwise the link 42 pushes the link 38 and operates the valve 20 to cause the clutch to engage, but when the pedal is rotated counterclockwise the valve member of 20 is already as far to the left as it can go and the spring 80 is merely extended by the pull on the link 42. The clutch-operating cylinder 12 is connected to the usual clutch pedal 10.

Title: Signal seeking radio receiver
IPC: H03J7/26
Filed: 1969-04-23
Abstract: 1,262,161. Radio receivers; automatic frequency control; transistor circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 23 April, 1969, No. 20656/69. Headings H3A, H3Q and H3T. In a signal seeking radio receiver tuned by varacter diodes in response to a voltage developed across a capacitor C, a first circuit T 1  is arranged to charge the capacitor and a second circuit T 2  is arranged to discharge the capacitor, both these circuits are arranged to operate simultaneously to maintain the charge on the capacitor C constant in response to a control signal U D  obtained from a received signal so as to maintain the receiver tuned to a desired first station and a switching arrangement S, K is operable both to interrupt the control signal and to change the charge on the capacitor, as selected, so cause the receiver to commence seeking in either direction, as selected, so that the receiver can tune directly to a next adjacent station of shorter or longer wavelength than the first station. To start a signal seeking process the contact K is temporarily closed and the timing direction of the signal seeking process is selected by switch S which in the position shown would cause discharge of the capacitor C. When the discriminator voltage at A becomes negative this causes transistor T 4  to switch ON which increases the current through transistor T 1  and decreases the current through transistor T 2  so as to stop discharge of the capacitor such that the capacitor voltage is adjusted to a constant value by the discriminator voltage U D  to ensure that the receiver remains sharply tuned. With the switch S, which may be an electronic switch, in its other position the discharge current through T 2 , R 2 , R 3  is made less than the charge current through T 1 , R 1  so that when a signal seeking process is initiated the capacitor C is charged. When a signal is received a positive voltage from the discriminator at A causes transistor T 3  to turn ON which decreases and increases the currents through the transistors T 1 , T 2  to stop charging of the capacitor C. The transistors T 1  and T 2  act as constant current sources to provide linear charge and discharge of the capacitor C. Forward biased diodes D 1 , D 2  compensate for temperature and stabilize the base-emitter voltages of the transistors T 3 , T 4 .

Title: Device for controlling the pressure medium of power-operated speed-changing mechanism
IPC: F16H61/02
Filed: 1935-07-22
Abstract: 458,694. Controlling change speed gearing. MAYBACH-MOTORENBAU GES. Friedrichshafen, Germany. July 22, 1935, No. 20837. Convention date, Aug. 8, 1934. [Class 80 (ii)] Relates to preselective servo fluid controlling - means for change-speed gearing, especially for vehicles, the compressed-air arrangements being preferred on account of their small size and weight. Preselection is effected from a handle 5, and the executive stroke in the servo cylinder selected is effected by depressing or by releasing the accelerator 11, by one or the other indifferently according to whether the vehicle is at rest or in motion. There are a number of ducts 38 leading to servo cylinders, not shown, and according to the selective operation by a selector 7 of one of a set of valves 8, pressure air (or suction) is admitted from a reservoir 1 eventually to the selected duct 38. In order that pressure air may reach the passage 10 of a valve 8 which has been selected and moved left, a master valve 32 has to be opened. This is done by a push rod 29 when pressure air is admitted at 26 to the left of a piston 27. The air reaches the passage 26 as a waist 24 in a poppet valve 23 passes over the end of a main pressure duct 2 one way or the other indifferently as to whether it is caused by a depression or by a release of the accelerator pedal 11. Air reaches the executive cylinder from another main duct 3 when the master valve 32 has been opened. There is described with reference to Figs. 2, 3 and 4 (not shown), a much more complicated arrangement embodying the two-position connector valve 97 of Fig. 2 in Specification 458,693. Besides the selector valve 81 shown in that Figure there are distributer valves 148 and 168 operated by the pressure air itself. This arrangement is especially applicable to change-speed gearing having claw clutches with repelling teeth as described in Specification 298,186, [Class 80 (ii)]. The same references by number are made in aid of the description as are used in Specification 458,693. Specification 369,864 also is referred to.

Filed: 1972-05-04
Abstract: 1320289 Fuel injection systems GENERAL MOTORS CORP 4 May 1972 [24 May 1971] 20843/72 Heading G1N In an I. C. engine intermittent fuel injection system, the inductance of an inductor, energized with a current having a linearly varying magnitude, is varied in response to the rate of change of an adjustable throttle member so as to develop across the inductor a throttle voltage having an amplitude proportional to the inductance, the amount of fuel delivered being regulated in response to the throttle voltage. As shown, injection valve energizing pulses are provided by a monostable circuit 92, the duration of the pulses being determined by the inductance of a transformer 94 in dependence upon the intake manifold vacuum, and by the magnitude of a bias voltage at a junction 118. The bias voltage is varied in dependence upon the throttle voltage provided by circuitry within a transient power controller 146, Fig.3 (not shown). Basically, this controller includes a throttle voltage generator responsive to the output pulses of the monostable circuit to develop the throttle voltage, and a bias voltage modifier which compares the throttle voltage with a reference voltage, which is preferably dependent upon engine speed, to develop a compensation current for determining the bias voltage. As shown in Fig. 4, the variable inductor 152 has a movable core 156 which is moved in response to throttle member movement (linkage 148) via a dashpot device 160. In this manner movement of the throttle member causes an initial displacement of the core and hence a value of inductance which is proportional to the rate of change of throttle member movement, the core thereafter returning gradually to its initial position.
