Title: Improvements in devices for testing spark plugs
IPC: H01T13/58
Filed: 1946-02-26
Abstract: 615,551. Testing sparking-plugs. TRIGGS, W. W. (Mallory & Co., Inc., P. R.). Feb. 26, 1946, No. 6012. [Class 7 (iv)] A device for testing sparking-plugs for gas tightness comprises a cylinder having a head in which an opening is formed adapted to receive a sparking-plug and a piston movable therein for building up an air pressure for testing the plug, a crank operable by a lever being provided for actuating the piston to build up a predetermined pressure in the cylinder and latching means being provided for latching the lever in actuated position. As shown, a sparking- plug 13, held in a head 11 of a cylinder 10 by a clamp 22, 30, 35, is tested for gas tightness by the pressure created by a single stroke of a plunger 50. The plunger has a sealing washer 49 and above this washer a layer of liquid such as oil is located. The liquid enables the clearance volume to be reduced to a minimum and thus increases the compression ratio. The plunger is operated by a hand lever 56 through the medium of a crank 53 and connecting-rod 51. The lever 56 is carried by a bracket 55 secured to a shaft 54 which also drives the crank 53. The bracket also carries a latch 61 which enables the lever to be fixed in various positions. The latch can be released by depressing a rod 65 which passes through the lever 56. The deflection of the lever 56 when holding the plunger against the pressure in the cylinder 10 can be used to indicate the magnitude of pressure and for this purpose the lever carries a graduated scale 80 which co-operates with a pointer 82 carried by the bracket 55. In a modification, a lever such as 22 is held by a pair of toggle levers, one of which acts on it through the medium of a compression coil spring.

Abstract: 1,208,571. Fuel Injection electrical control systems for I.C. engines. ASSOCIATED ENG. Ltd. Feb.1, 1968 [Feb. 8, 1967], No.6101/67. Heading G1N. A fuel injection control system for vehicle I. C. engines includes a discriminator circuit, Fig. 1, which produces an output voltage having a desired characteristic in relation to engine speed (e. g. as shown Fig. 2 or as in Figs. 3a to 3l (not shown). The discriminator output voltage is used as a component of a control voltage fed to a control pulse generating circuit, not described (e. g. voltage V 1  in circuit Fig. 2 of Specification 1, 107, 989), the duration of pulses from which controls the duration of injection period. The discriminator includes a mono-stable multi-vibrator TR 1 , TR 2  which is triggered to its unstable state by pulses from a distributer D occurring at a rate proportional to engine speed. The multi-vibrator produces output pulses of constant width independent upon the rate of triggering, which pulses are integrated in integrating circuits one of which comprising TR 3  RV 2 , C6 produces an output at low engine speeds and the other of which comprising TR 4 , RV, C5 produces an output at high engine speeds. The integrator outputs voltages at the emitters of TR 3 , TR 4  are linearly proportional to engine speed and are combined at amplifier TR 5  to produce the output characteristic of the discriminator circuit which appears at the emitter of TR6. Either the high speed integrator or low speed integrator may be omitted.

Title: Improvements in devices for controlling transmissions with variable speed, particularly in the case of motor cars
Filed: 1931-02-26
Abstract: 369,361. Controlling variable-speed gearing. FLEISCHEL, G., Bleneau, Yonne, France. Feb. 26, 1931, No. 6105. Addition to 356,139. [Class 80 (ii).] According to the parent Specification, variable-speed gearing for a vehicle is operated automatically by engine suction at 31, Fig. 2, through a " main control lever 14 " which through an electrical relay and cams effects the speed-changing and engine clutch operation. In this invention, the action on the lever 14 is regulated by a roller 97 movable between one lever, in this case the lever 14, and another lever 95 so that the leverage of one lever decreases as that of the other increases. The roller 97 is moved by an auxiliary pressure device, in the arrangement shown, further engine suction at 31a. The main suction diaphragm 31 acts on the lever 95 through a linkage comprising a stabilizer 18. Astabilizing plunger 18 is pressed into a notch 17 by a spring 35 and part 34 of the linkage. A modification is described comprising two of these oppositely-directed lever pairs in which the auxiliary pressure device includes water from the engine cooling system. In this modification, the stabilizer is a lever carrying two bowls which come into action alternatively at two different leverages, and regulation is imposed by a multiple camshaft. The auxiliary pressure fluid may be derived from the lubricating system. A device comprising a sliding multiple cam plate is described operated by the relay electric motor. In Fig. 4 is shown an arrangement in which multiple cam grooves are formed in a drum 317 which encircles the change gearing 319 and is angularly displaced to effect changes by the relay motor 324.

Title: Improvements in the reception of wireless signals
IPC: H04B1/12
Filed: 1922-03-01
Abstract: 198,428. Round, H. J. March 1, 1922. Atmospherics, eliminating or limiting.-For the purpose of eliminating atmospheric disturbances, a receiving system comprises four aerials A, B, C, D, forming two pairs A, B and C, D. The aerial A is tuned to the signal frequency whilst the aerial C is tuned to some other frequency, the difference in tuning between A and B being made the same as that between C and D. Tuned circuits E, F, J and G, H, L are so connected to a final detector circuit N that beat currents between atmospheric received by the aerials A and B are balanced out against those received on the pair C and D. Signal impulses, however, do not balance out in the final circuit. By comparing simultaneous records of the energy received by one aerial against currents recorded in the final detecting circuit, it is possible to ascertain (a) the required signal, (b) whether or not atmospheric impulses have occurred, and (c) whether such atmospherics coincide with the signal marking times or with the spacing intervals. Instead of using four separate aerials, two aerials each having two natural periods of oscillation, or one aerial having four differently-tuned or two doubleperiod circuits may be used. The signal energy may be trasnmitted on two different wave-lengths which create an audible beat frequency. Further, the four aerials may be impulsed locally by means of a buzzer P so as to provide " artificial " atmospherics of a strength that can conveniently be balanced out, leaving the signals free to be recorded in the final circuit.
