Title: Improvements in method and apparatus for the electric transmission of pictures and views
IPC: H04N5/30
Filed: 1925-09-23
Abstract: 240,463. British Thomson-Houston Co., Ltd., (Assignees of Hoxie, C. A.). Sept. 23, 1924, [Convention date]. Controlling copying - telegraphs; oscillation generators.-In a picture or like transmission system in which light from successive small areas of the picture &c. to be transmitted is incident on a photo-electric cell, the light is interrupted to produce a wave of radio or other carrier frequency. In one arrangement, Fig. 1, a finely-toothed disc or a transparent disc with opaque radial lines, as shown at 32, is rotated rapidly in the path of the light falling on the cell 7. The cell is in a circuit from a battery 36 through a resistance 37, and the varying fall of potential across this resistance is amplified by a thermionic valve 38 of which the plate circuit is connected through a transformer 44 to the line wires 45 or to wireless transmitting apparatus. An alternating-current generator 47 driven by a motor 26 driving the image-exploring devices supplies a synchronizing current through a transformer 48. At the receiving station, Fig. 2, the current is delivered by wires 51 directly connected with the wires 45 or with wireless receiving apparatus, and is amplified by valves 52 and 70, of which the plate circuits are connected through transformers 53 and 69 with the electrodes of a discharge lamp 54 and with an electromotor 67 respectively. Tuning condensers 56 and 71 are bridged across the secondaries of the transformers 53 and 69 to separate the carrier and synchronizing frequencies respectively. The light from the lamp 54, varying in intensity in accordance with the lights and shades of the successive elemental areas of the original image, is used for reconstructing the picture. For interruption at a lower frequency a rotary disc with evenly-spaced apertures may replace the disc 32, and the synchronizing frequency may be similarly obtained. A stationary finely-ruled screen or a fine grating may be used in place of the rotary interrupter, or the required interruption of the light may be obtained by the use of a discharge lamp fed with alternating or pulsating current having the carrier wave frequency.

Title: Improved indicating and calculating apparatus
Inventor: HENRI BOUTILLON
IPC: G06C15/42
Filed: 1963-06-17
Abstract: 981,717. Counting-apparatus. ESTABLISSEMENTS BOUTILLON S.A. June 17, 1963 [July 13, 1962], No. 24067/63. Heading G4D. In zeroizing a counter transfer mechanism is moved so as to be disengaged by the gear of lower denomination while still being partially engaged with the gear of the higher denomination. The invention is applied to liquid, dispensing apparatus of known type in which unit price, volume and total price are indicated on both sides of a pump. Before a dispensing operation a crank is oscillated to drive a carriage 34, Fig. 5, to the right and then release it to return under spring action whereby pawls 46, 48, drive a pair of gear wheels such as 69 controlling opposed sets of counters through a quarter revolution. Gear 69, for example, rotates cam 72 and arms 107 through half a revolution. Cam 72 rocks lever 74 to rotate eccentric shaft 78 to disengage drive gears 18 from the counters. At the same time levers 90, Figs. 7, 12, are rocked to move transfer pinions 88 away from the numeral wheels, so that the eight-toothed Geneva-type side of a pinion 88, Fig. 10, is free from the lower denomination gear 86 but the sixtoothed side of the pinion 88 still meshes with the higher denomination gear 87, Fig. 9. Rollers on arms 107 then rock levers 97 whereby rollers 93 on spring-pressed arms 95 hit heart-shaped cams 92 to return the numeral wheels to zero position. If one of the rollers 93 should meet the point of a heart-cam exactly the spring-pressed arm 95 yields but lever 97 continues its movement until a nose 108 touches the cam 92 to move it from deadcentre position. French Specification 1,033,026 is referred to.

Title: Improvements in or relating to variable speed reduction gear mechanism
IPC: F16H37/08
Filed: 1933-08-31
Abstract: 422,288. Variable speed gearing. BENSON, M. B., 52, Vanderbilt Avenue, New York, U.S.A. Aug. 31, 1933, No. 24193. Convention date, April 24. [Class 80 (ii)] Variable-speed epicyclic gearing comprises a restraining-arm 12, pivoted externally of the gear-elements, for restraining the rotation of a gyratory pinion 10 on an eccentric 11 which gyrates the pinion inside an internally-toothed annulus 7. For varying the speed, the arm 12 is allowed to rotate at varying speeds, in the direction of the gearing-thrust, through variablegearing or by means of an independent-variablespeed electric motor. In Fig. 1, the eccentric 11 is secured to the driving shaft 1, and the annulus 7 to the driven shaft 2. The restraining-arm 12 is pivoted externally in a ring 20 and has a forked inner end embracing a second eccentric 14 integral with the eccentric 11, the arm having also a pin 15 engaging a radial slot in the gyratory pinion 10. When the ring 20 is stationary a reduced drive is transmitted and by allowing it to rotate at increasing speeds, the speed of the driven shaft 2 is further reduced. The ring 20 has worm-teeth 20' engaged by an irreversible worm 25, which is variably driven by a friction-disc 27, engaged by a roller 28, movable by screw-means 35 along a shaft 29, driven by a belt 33 from the driving shaft 1. The upper bearing 43 of the shaft 29 is spring-pressed, the lower being self-aligning. The operating-nut 36 is linked to an indicating- pointer. Alternatively the worm 25 may be driven by an independent motor, or, in the case of a bobbin drive in textile machinery, by means controlled automatically by the filling of the bobbins. To preserve uniformity of drive, the ratio of the throws of the eccentrics 14, 11 is equal to the ratio of the distances between the axis of the shaft 1 and the pivot 13 of the arm, and between the pivot 13 and the mean position of the pin-and-slot connection 15. In the modification shown in Fig. 5, a shaft 50 drives, through bevel-gearing 60, 59, a casing 55, in which the outer end 68 of the restraining- arm 67 is pivoted. The annulus 62 is again secured to the driven shaft 51, but control is effected through the double eccentric 65, 70 which forms self-locking means which causes the gearing to rotate solidly. To reduce the speed of the driven shaft, a shaft to which the double eccentric is secured, is variably braked by disc-and-roller gearing 82, 73 driven by the driving shaft 50. In the solid-drive position shown, the roller 73 lies out of contact with the recessed centre of the disc 82, which is spring-pressed upwardly to a limited extent. The speed-ratio may be caused to vary by electric or hydraulic means. Specification 408,426 is referred to.
