A vehicle hydraulic transmission comprises a pump 2 supplying a motor 3 through flow and return lines 6, 7 and provides braking on overrun due to the action of a valve 13 which closes the return line 7 on overrun so that the return flow occurs through a by-pass line 18, 26 provided with a restriction 20 which is adjusted in accordance with the position of a brake pedal. The by-pass also incorporates a radiator 24. The valve 13 is subject to the pressure in the flow line 6 which is applied to a chamber 15 to urge the valve downwardly towards its open position against the force of a spring 21 and the pressure in the return line which is applied to a chamber 16. On overrun the fall of pressure in line 6 and rise in line 7 causes valve 13 to close the return line 7. The flow and return lines incorporate a reversing valve 30. In a modification the valve chamber 16 is subjected to an independent source of pressure. In a second modification (Fig. 8) a pump 205 for the vehicle servo system also selectively supplies the valve chamber 15 or 16 under the control of a valve 200 actuated by an accelerator pedal 203, the other valve chamber being opened to exhaust, the arrangement being such that the valve chamber 15 is pressurized if the accelerator pedal is depressed so that the valve 13 is open and the chamber 16 is pressurized when the pedal is released so that the valve 13 is closed and braking is provided.

Title: Improvements in feeler control devices for controlling feed movements in machine tools
IPC: B23Q35/34
Filed: 1935-09-30
Abstract: 460,791. Electric control systems. SIEMENS - SCHUCKERTWERKE AKT.- GES. Sept. 30, 1935, No. 26987. Convention date, Oct. 2, 1934. [Class 40 (i)] In a feeler control device for controlling the feed motions between the cutter and work in machine tools, and particularly adaptable for copying-lathes and copying milling-machines a nozzle bolometer of known form is operated by the feeler and is utilized to produce electric control impulses for controlling the feed motions. As applied to a copying-lathe or milling-machine, the feeler 1 which contacts with the pattern is mounted by means of a semi-spherical part 2 in a casing 3 attached to a base 19 which may be secured to the sliderest &c. of the machine. A ball 4 at the rear end of the feeler engages a spherical recess 5 in a lever 20 pivoted at 6 on a bracket 21 secured to the base 19. A second arm 10 on the lever 20 carries a shutter 11 for co-operating with two nozzles 12, 13 of a nozzle bolometer, which consists of two heated branches of a temperature-sensitive electric bridge circuit which are normally cooled by two currents of air from the nozzles, the air currents being of equal amount in the neutral or zero condition of the apparatus. Oscillation of the lever 20 by pressure of the pattern on the feeler causes the shutter 11 to obstruct one or other of the nozzles by a variable amount, thus cutting down one of the air currents and varying the resistance of the corresponding branch of the bridge. The electric impulses so produced are used to operate an electric discharge rectifier having one or more control electrodes, which in turn controls the feed mechanism, such as magnetic couplings. A spring 8 biasses the lever 20 in a clockwise direction and stops 15, 16 limit the movements of the shutter 11. Damping means for the control may be provided to reduce the frequency with which changes of feed are effected. The arm 10 and shutter may be adjusted relatively to the lever 20 by means of a slot and screw 18.

Patent GB-274344-A (GB)
Abstract: 274,344. Pilgrim, G. J. M. Dec. 9, 1926. Adding and subtracting apparatus; connections to typewriters.- In a calculating typewriter such as that described in Specification 260,894 having a number of column totalizers bcd and a line totalizer e adapted by its condition, to control the keys, the parts are modified to adapt the machine for dealing with computations relating to consecutive numbers such as those borne by coupons, and to this end mechanism is arranged to lock the keys at the beginning of an operation unless the line totalizer stands at unity. As is usual, the keyboardlocking lever o is retained in its effective position by the projection p<2> of the totalizer carriage p and also by the lever controlled by the latch h. To type and calculate the inclusive number of coupons lying between two numbers, unity has first to be entered on the totalizer e and for this purpose the totalizer is shifted fully to the left by manipulation of a bell-crank lever v to bring the units wheel into actuating position. The end v<1> of this lever is thus brought against one arm of a lever x<3> pivoted at x<2>, the other arm bearing against a collar i<1> on the link i<1>. The latch h is therefore rocked to release the lever j which consequently moves lever o into locking position and retains it there. The totalizer e having been actuated by the depression of the key lever is then returned to its normal position and if it stands at the comb m<1>, Fig. 6, has rocked counterclockwise owing to the receiving-pinion n of the counter being mutilated at zero except in the units denomination where the pinion is mutilated at 1. This rocking of the comb has shifted the end k of lever k<1> into the plane of the lever j<1> and consequently when the totalizer e is restored by the operator to normal position this lever j<1> is rocked by the end k and is re-latched, the lever o being thus freed to unlock the keys as soon as the totalizer moves forward. Unless therefore the totalizer has been properly cleared and then actuated to register 1 the lever j<1> is not re-latched and the lever o continues to lock the keys.
