Title: Electronic Speed and Distance Indicator System
Inventor: BATES TREVOR
IPC: G01P3/48
Filed: 1967-11-30
Abstract: 1,187,420. Selective signalling. GENERAL MOTORS Ltd. 28 Nov., 1968 [30 Nov., 1967], No. 54490/67. Heading G4H. [Also in Division G1] The speed of a motor vehicle is measured by an 8-pole magnet mounted on the output shaft of the vehicle, associated with a reed switch which is thus closed eight times per revolution, each closure short-circuiting a capacitor C1 (Fig. 1) through diode D1. When the switch is open, capacitor C1 is charged to the battery voltage via R1, T1, T2, the charging pulse, of constant amplitude and duration, being amplified by transistors T1, T2 and fed to a coil L1, mounted perpendicularly to a coil L2 fed with a constant current, whereby a magnetic pointer (not shown) lines itself up with the direction of the resultant flux which is indicative of the average current through coil L1 and therefore proportional to the pulse frequency and the vehicle speed. The pulses fed to coil L1 are also used to charge a capacitor C2. After say 200 pulses the charge on C2 discharges through a uni-junction transistor T3 to feed a pulse to coil L3 of a stepping motor coupled to an odometer pointer.

Title: Improvements in or relating to the reflex copying of prints
Inventor: LOPREST FRANK JAMES
IPC: G03G5/028
Filed: 1967-12-19
Abstract: 1,207,367. 367. Thermographic processes and apparatus. GAF CORP. Dec. 19, 1967, [Dec.30, 1966], No. 57696/67. Headings G2A and G2C. A thermographic process comprises image-wise reflex exposing to heat a two-composent diazotype material containing a substance which releases water on heating, placing the material between two electrodes with the exposed layer in contact with the cathode, passing a current to electrolyse the water and produce alkali at the cathode which causes image-wise coupling of the diazonium compound and the coupler. The developed material may be fixed by uniform exposure to ultraviolet light. Specified substances which release water on heating are the hydrated salts of lithium metaborate, sodium sulphate, sodium dihydrogen phosphate, borax, sodium alginate and sugar. The invention also comprises a thermographic exposure and development apparatus for the above material comprising a source of infrared radiation, means for exposing the material to the source and means for passing an electrical current through the material using two electrodes and a source of electrical current. The infraradiation source is preferably in a rotating cylinder. As shown, the heat sensitive material C containing diazoium compound, azo coupler and a substance which releases water on heating (either one which contains water of crystallisation or a hygroscopic substance) and original D are placed in slot 9 and are passed round rotating cylinder N containing an infrared source 17 so that material C is reflex exposed. The material C and original D are held in contact with the cylinder by an endless belt 12 and after exposure the original D is separated from the material C by means 20. The material C, bearing a latent water image, passes between rollers 25 and 26, acting as anode and cathode respectively, so that the water is electrolysed and hydrogen is released at cathode 26 creating an alkaline environment and allowing coupling to occur. The material C is now uniformly exposed to ultraviolet light 27 to decompose the remaining diazonium compound and fix the image.

Abstract: 1354630 Setting electric watcher DAINI SEIKOSHA KK 19 Dec 1972 [27 Dec 1971] 58555/72 Heading G3T Upon pulling out a setting stem 16b of a tuning fork watch, the electricity supply is disconnected, thus stopping the oscillation of the tuning fork 2, and the gear train between the tuning fork and the seconds hand is prevented from moving; upon pushing in the stem the supply is reconnected, the gear train is released and an impulse is imported to the tuning fork to restart oscillation. In normal use magnetic blocks 2a, 2b on the tuning fork are driven by a coil 6 of a circuit block 4 which is powered by a battery 15 via a switch comprising a pin 21 and a spring 20. When the stem 16b is pulled out, a setting lever (not shown) rotates a lever 18 so that an insulating portion 18b moves spring 20 away from pin 21 thus opening the switch. At the same time the movement of the end 16a of the stem permits a lever 22 to rotate under the action of a spring 24 to engage a third wheel 12 and prevent rotation thereof. Wheel 12 is part of a gear train comprising an index wheel 8, driven by a rod 7 fixed to the tuning fork, and wheels 10, 11, 12 and 13, the last of which drives the seconds hand. When the stem is pushed in, a spring 25 mounted on lever 22 impacts on a projection 2c of the tuning fork which thus immediately begins to execute full oscillations.
