Abstract: 1,057,359. Controlling hydraulic couplings. DIESELMOTORENWERK SCHONEBECK VEB. Aug. 24, 1965, No. 36415/65. Headings F2C and F2D. Filling and emptying of an hydraulic coupling driving an engine cooling fan is controlled by a valve actuated by temperature responsive means having thermally expansible fluid, the valve being biased by a spring towards a position such that, in the event of leakage of the thermally expansible fluid, the hydraulic coupling is filled. As shown, a valve 4 has a groove 5 registering with bores 2 when the temperature responsive means is defective so that the coupling is filled, the groove 5 registering with bores 3 to fill the coupling at a predetermined engine temperature when the temperature responsive means is functioning correctly. When the engine is cold and the temperature responsive means is functioning correctly the valve position may either be such that the coupling is empty, or be such that the bores 2 are open and close as soon as the engine begins to warm up. As a modification the valve may have a pair of grooves selectively registerable with a single pair of inlet and outlet bores.

Title: Apparatus for checking the ignition timing of an internal combustion engine
Inventor: WEIDNER RALPH JUNIOR
IPC: F02P17/04
Filed: 1957-11-25
Abstract: 831,671. Electric tests. ALLEN ELECTRIC & EQUIPMENT CO. Nov. 25, 1957, No. 36639/57. Class 37. A device for checking ignition timing comprises a pair of thyratrons the first of which is triggered by a pulse derived from the ignition circuit and which triggers the second after an adjustable time delay to flash a stroboscopic lamp. When the delay is adjusted so that conventional timing marks on a fixed and moving part of the engine appear in alignment a measure is obtained of the amount by which the spark is advanced. As shown, a pulse derived from a clip attached to a sparking plug sets up oscillations in a circuit consisting of inductance 69 and the cable capacitance. The positive component of the oscillations trigger thyratron 56. The change in potential at the cathode of the thyratron allows condenser 49 to discharge through variable resistor 51 until after a period determined by the setting of this resistor, thyratron 33 triggers allowing condenser 52 to discharge through it and through transformer primary 34 the secondary of which controls flash tube 21. The potential increase on line 43 cuts off thyratron 56. The flashing of the tube is arranged to illuminate a mark on the flywheel or other rotating part of the engine and resistor 51 is adjusted until this mark coincides with a fixed mark. Meter 58 in the anode circuit of thyratron 56 indicates the average current through the thyratron and may be calibrated in terms of ignition advance. Meter 41 in the anode circuit of thyratron 33 passes current during conduction of thyratron 41 and charging of capacitor 52 in each cycle and may be calibrated in terms of engine speed. Rectifier 42 prevents discharge of capacitor 52 prior to firing of thyratron 33 which would make the engine speed reading vary with ignition advance. Various modifications are proposed (Figs. 5 and 8, not shown) in which one or more of the rectifier speed meter, and the flashing transformer are in the cathode circuit of thyratron 33 and the ignition advance indicating meter is in the cathode circuit of thyratron 56. Specification 741,028 is referred to.

Title: Current multiplication transistor
IPC: H01L29/00
Filed: 1954-12-20
Abstract: 790,855. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1954 [Dec. 23, 1953], No. 36728/54. Class 37. A transistor of the current multiplication type comprises a semi-conductive body, a base electrode, two emitter electrodes and two collector electrodes in which one emitter is substantially nearer one collector than the other collector and the second emitter is spaced substantially equal distances from both collectors. In the Figure a point contact transistor has two emitters 3e, 4e and two collectors 5c, 6c. Only one of the collectors (6c) serves as the output electrode. The first or signal input emitter 4e is located very near the output collector 6c and the second emitter 3e is located midway between the two collectors 5c, 6c. The Figure uses N-type material 1 and initially most of the holes from emitter 3e flow to the collector 5c so that only a small hole current flows through to collector 6c. When holes start to flow from emitter 4e they are attracted to collector 6c so that the electron current from collector 6c increases. This increased electron current increases the electric field of collector 6c to attract more of the holes from emitter 3e and the increased flow of holes further amplifies the electron flow from collector 6c. The body 1 may be P-type with consequent reversal of current direction and polarities. Specification 790,403 is referred to.

[Class 106 (i).] In a machine such as that described in Specification 259,267, [Class 106 (i), Calculating &c.], wherein the numeral keys are locked against use when the line totalizer actuator passes beyond the lowest denomination the keys are locked and unlocked twice during the operation of the transfer-restoring means. The actuator 13, Fig. 1, is coupled to a rack 23 geared by pinions and a shaft 27 with another rack 24 to which is pivoted at 411 a lever 29 controlled by a spring 32 which thus urges the rack 24 to the left and the rack 23 to the right. During the letter-spacing movements of the carriage 1 the rack 24 is held fast by engagement with a stationary column stop 33, of a lug 40 on the lever 29 but when the lowest denomination of the line totalizer has been reached and passed a cam 38 on the carriage depresses the lever to clear the stop. The rack 23 cannot however return under the action of spring 32 to restore the actuator 13 to its highest denominational position owing to the action of a latch as described below. The numeral keys are controlled by the usual crowding locks 19, Figs. 6 and 10, the end one of which however is divided as shown at 21, 22 to receive and be spread by a finger 50 pivoted on a lever 48. As the carriage travels beyond the lowest denomination a cam 44 on the rack 23 raises a lever 45 and thereby the lever 48 so as to spread the lock 21, 22 and prevent further use of the keys. The locking condition is maintained by a slide 52, Fig. 8, which can now enter a notch in the rack 23. To unlock the keys and rack the transfer-restoring key 17 must be depressed so as to lower the slide by means of a pin 54 mounted on the key. During both the down and up strokes of this key a lever 56 having a cam slot 57 is rocked by the pin 54 to draw the end of a rod 60 beneath a projection 62 so as to raise the lever 45 into locking position. The line totalizer may be moved still farther to the right in which position it is locked by a key 64 engaging another notch in the rack 23 the numeral keys now being unlocked. Upon depression of the key 64 the carriage and rack return again one step to the right and the numeral keys are again locked.
