Abstract: 865,632. Make-and-break switches, mechanical; pressure actuation of switches. KELVIN & HUGHES Ltd. June 18, 1957 [June 28, 1956], No. 20044/56. Class 38 (5). [Also in Group XXXV] A cycling switch in which the on/off ratio (used to adjust fuel and air supply to a boiler, see Group XXXV) depends on steam pressure and steam flow is shown in Fig. 2, in which steam pressure acts on a bellows 34 and so on a beam 35 pivoted at 36 against the action of spring 37, and steam flow determines the position of a lever 47 pivoted at 48 through the action of a cam 49 on a conventional flow-meter shaft. Pivots 39, 46 on the beam 35 and lever 47 respectively therefore set the mean position of a lever 40 in accordance with the pressure and flow, and a cam 44 on the shaft of a constantspeed motor 45 superimposes an oscillatory motion on this mean position through the action of lever 43 pivoted to 47 at 46 and to 40 at 42. A tilting mercury switch 41 thus closes for periods of time dependent on boiler demandi.e. increasing with low pressure and/or high flow. For water-heater control, temperatures may be converted into pressures by a temperature sensing bulb (mercury or gas).

Abstract: 756,947. Lathe details. BATIGNOLLES CHATILLON, [formerly COMPAGNIE GENERALE DE CONSTRUCTION DE LOCOMOTIVES BATIGNALLES - CHATILLON July 21, 1953 [Nov. 5, 1952], No. 20230/53. Class 83 (3). The cycle of movement of a tool-carriage 10, Fig. 1, of a machine tool, e.g. a lathe, which cycle consists of the rapid approach, operative feed of the tool into the work, and rapid withdrawal, is effected by a piston 13, Fig. 3, operated by hydraulic-fluid under the control of a valve 22, Fig. 5. The fluid is supplied by pump 30 to cylinder-space 32 via line 33, and to cylinder-space 39 via line 40 and bore 41 in the piston, the pressure in space 39 being controlled by the valve which, when the solenoid 26 is energized, is pressed down by spring 24 to open port 42 and connect line 40 to the fluid reservoir 31 via line 43. The piston then causes the carriage to approach the work and is stopped when the valve abuts a part 21 of a rack 18 slidable endwise in the carriage-support 1. The rack meshes with a pinion 19 on a shaft 44 engaging a worm-wheel 47 through a free-wheel 45, and wheel 47 meshes with worm-shaft 49, the device holding the rack stationary when shaft 49 is stationary. Rotation of the shaft is controlled by solenoid 58 and in one direction, the free-wheel is released permitting spring 24 to lower the valve and the rack, whereby the tool is fed into the work. At the required depth the carriage actuates contacts to de-energize the coil 26, whereupon the piston causes rapid withdrawal of the carriage which carries with it the rack. The feeding-speed of the tool into the work is variable by varying the speed of shaft 49, and the direction of rotation of the shaft is reversible to raise the tool. Support 1 is mounted on bars 2a, 2b and clamped in the required position. Shaft 49 is driven from the headstock spindle 54 via pulleys 53, 57 and change-speed gears 60, 61.

Title: Improvements in and relating to film driving mechanism for sound recording or reproducing apparatus
IPC: G03B31/02
Filed: 1928-07-13
Abstract: 295,379. British Thomson-Houston Co., Ltd., (Assignees of Hoxie, C. A.). Aug, 12, 1927, [Convention date]. Film-feeding mechanism; optical apparatus.- Relates to sound-recording or reproducing apparatus wherein a film is driven by sprocket mechanism and a friction-drum device (or " belttype drive ") acting in conjunction. According to the invention, the film is fed towards and away from the friction drive device by a single sprocket-wheel, the belt-type drive operating at a substantially constant speed, whilst the speed of the sprocket-drive is automatically controlled in accordance with the position of a movable member controlled by the relative lengths of film approaching and leaving the belt-type drive. By this means the rates a,t which the film is fed by the two driving-devices are maintained slibstantially equal. In the reproducing apparatus shown, the film 1 in passing from a reel 2 to a reel 3 engages opposite sides of a sprocket-wheel 4, which feeds the film over a belt-type driving member consisting of a drum 24, within which a photo-electric cell 55 is arranged to receive light passing through a slit 51 and through the film. Between the sprocket- 4 and the drum 24, a carriage 14, mounted to travel on a track 16, carries two rollers 17, 18 over which the film passes, these rollers being so spaced that the film forms oppositely disposed loops 19, 20. A pair of levers 7, connected by a spring, each carry two rollers holding the film against the sprocket 4, and rollers 21, 22 are mounted on fixed pivots as shown. Two electro-motors are provided, the main one 27, driving the sprocket 4 and the reels 2, 3 through suitable means such as the belt arrangement shown. The drum 24 is driven by a small motor 38 having a speed regulator which keeps it running at a constant speed. The shafts of both motors may be connected together at starting a clutch 46, controlled by a centrifugal device 47, being provided on a countershaft 45 for this purpose. The arrangement is such that the two motor shafts are uncoupled just before normal running speed is reached. The motor 27 has a shunt field 32, rheostats 33, 34 controlling the field current. Coarse adjustment of the speed of the motor 27 is obtained by hand operation of the rheostat 33, while the fine regulation is automatically pro-. duced by the rheostat 34, of which the moving contact 35 is carried by the carriage 14. Any variation in speed of the sprocket 4 results in a movement towards the right or left of the carriage. 14, thus increasing or decreasing the resistance in the field circuit of the motor 27. In a modification, the rheostat 34 is replaced by a pivoted-arm contact-device which controls the resistance in the field circuit through a series of relays. For recording sound, the film-driving apparatus shown may be used in conjunction with apparatus such as is described in Specification 180.236.
