Title: Improvements in voltage regulator devices
Inventor: JENNINGS ROBERT EDWIN
IPC: G05F1/14
Filed: 1954-04-14
Abstract: 775,742. Transformers. FOSTER TRANSFORMERS, Ltd., JENNINGS, R. E., and STEWART, 1. R. MAXWELL-. April 13, 1955 [April 14, 1954], No. 11012/54. Class 38(2). A voltage regulating device incorporating an on-load transformer tap-changing system comprises coarse and fine switches mechanically coupled through a reduction gear, the coarse switch co-operating with tappings on the transformer and the fine switch supplied from a further transformer and arranged to inject a variable voltage into the output circuit. A coarse switch comprises two contacts 18, 19 moving together over studs 11 ... 17 con. nected to tappings on a transformer winding T. The fine switch comprises a movable brush 5 associated with secondary windings 3, 4 of a toroidally wound transformer, the primary winding 2 of which is energized from a further transformer winding 20. The secondary windings 3, 4 are connected to the moving contacts 18, 19 of the coarse switch and the maximum voltage from each secondary winding is made equal to half that which exists between the tappings, or studs, of the main transformer winding T. Assuming an initial zero voltage position with both moving contacts 18, 19 on stud 11, then as the brush 5 is rotated over a winding 3 or 4 the voltage of the output circuit O will be increased up to half an increment when the brush 5 has moved half a revolution. At this point the contact 19 will move to stud 12 but the voltage of the output circuit O will remain at half an increment because the Winding 3 or 4 opposes the voltage derived from the main winding. Further rotation of the brush 5 now decreases the opposing voltage until when the brush 5 has completed one revolution the opposing voltage is zero and the voltage of the output circuit O will be one increment. Continued rotation of the brush 5 will still further increase the voltage of the output circuit. Apparatus according to the invention may be associated with that of Specification 775,741. The toroidally wound transformer 2, 3, 4 is. of circular outer configuration and has a contact moving around it in direct contact with the turns thereof and associated with a further contact co-operating with a slip-ring. Each secondary winding may be in two parts wound alternately one beside the other and each connected to its associated circuit through current limiting resistors. Specifications 607,347, 619,474, [Group XXXVII], 675,615 also are referred to.

Filed: 1933-04-13
Abstract: 416,519. Surfacing - rolls for metal, paper, &c. CRAVEN BROS. (MANCHESTER), Ltd., Vauxhall Works, Reddish, near Stockport, and WALLS, A. G., 295, Broadstone Road, Heaton Chapel, Stockport. April 13, 1933, No. 11071. [Class 60.] A finished surface is produced on a roll for rolling metal, paper, or other substances by a number of spaced narrow segmental laps h which are shaped to the surface of the roll and are reciprocated axially of it at a relatively high speed whilst the roll is rotated relatively slowly, so that the laps trace a zig-zag course on the surface of the roll, the laps being restrained from movements radially to the roll by a weight or spring exerting substantially constant pressure, and being positively restrained from any other movement. In the apparatus shown, the laps are mounted, with freedom to move vertically, in fingers g secured to a rod c which is reciprocated by a crank d and connecting rod e. They are pressed against the work by weights n suspended from bows m carrying pointed pegs k seated in recessed holes j, in the laps. The reciprocation of the rod c is greater in extent than the distances between the laps, but less than the width of a lap. The laps may be gradually or intermittently moved axially, for example by means of a right and left hand nut f in the connecting rod e ; or the roll itself may be moved axially. To prevent the laps traversing continuously the same path, the crank d is driven by a slipping belt drive. For cambered rolls, narrow laps with short axial reciprocation are employed. Another apparatus is described in which the bed of a grinding machine is extended so that the table carrying the roll may be moved to bring the roll to the lapping apparatus, which comprises superposed slides the upper of which carries the lap holders, and is movable to adjust the laps radially to suit the diameter of the roll, whilst the lower slide is reciprocated axially by an eccentric to reciprocate the laps on the roll. The laps are pressed against the roll by pegs similar to the pegs k, but which receive pressure from weighted levers.

Abstract: 835,293. Gas turbines; Jet-propulsion plant. NAPIER & SON Ltd., D. April 3, 1958 [April 4, 1957 (2); April 10, 1957], Nos. 11082/57, 11085/57 and 11816/57. Class 110(3). A propulsion engine for high-speed aircraft or missiles includes auxiliary mechanisms or systems employing liquid media in at least two separate closed circuits, each including a heatexchanger, the liquid fuel for the engine being passed through these heat-exchangers in series. Engine fuel from a tank 55 (see Fig. 2), after passing through a heat-exchanger 56 to cool parts of the associated aircraft, is pressurized by a pump 58 to raise its vaporization temperature before passing through heat-exchangers 59, 60 arranged respectively in a lubricating-oil circuit and a servomotor oil circuit. The lubricating oil is thus cooled to a lower temperature than the servomotor oil. The jet propulsion engine, Figs. 1A, 1B, comprises a compressor 15 coupled by a freewheel 28 to a turbine 30 fed from a rockettype combustion chamber 31, 32. The compressor feeds the combustion chamber 17 feeding the jet nozzle. This chamber 17 also receives the turbine exhaust and is provided with burners 18. At a predetermined Mach number sensed by a meter 34 the supply of fuel and hydrogen peroxide to the chamber 31, 32 is cut off, and the servomotors 43, 47 and 38 respectively close the flaps 41 and open the flaps 44 and the air by-pass valves 36. The servomotor 38 also feathers the compressor stator blades 39 so that the compressor can windmill and the engine function as a ram jet. The position of the bullet 20 is varied by a further servomotor 21. Specification 835,295 is referred to.

Title: Improvements in roller chain sprocket wheels
IPC: F16H55/30
Filed: 1941-09-03
Abstract: 551,756. Chain wheels. KLAUCKE, H. Sept. 3, 1941, No. 11273. [Class 80 (i)] Consists in a sprocket wheel, for use with roller chains having side plates, which will compensate for inequalities of pitch in certain links of the chain due to wear and ensure that the chain as a whole will operate on a true pitch circle. According to the invention, alternate teeth of the wheel are of conventional form, those between them being shorter and having their profile faces sloping at a greater angle to a normal, the conventional teeth being adapted to be straddled by the pin links and the blunter teeth by the roller links. Fig. 1 shows a wheel all the teeth 18 of which are of conventional form and in which, due to wear, the pin links 14 have become elongated in pitch causing an increase of the distance between the centres of the rollers 16 with the result that the rollers ride higher on the teeth. Wear does not have the same effect on the roller links 20 and therefore pin and roller link pitches have become unequal with the result that the forward roller of each roller link is caused to ride even higher on the teeth than the rear roller link and therefore the chain does not run on a true pitch circle. In Fig. 2 it is seen that the forward roller 26 does not even engage its tooth and carries no load at all. In Fig. 4 is shown the long conventional teeth 32 alternating with the shorter and blunter teeth 34 the latter being relatively broader at the base so that the rollers will, when new, seat therein. As the pitch of the pin links increases and the teeth and rollers wear, the chain as a whole runs on a larger pitch circle, but it is still a true circle. A method of obtaining the shape of the teeth 34 by plotting from successive roller positions on the teeth 32 is described with reference to Figs. 5, 6 (not shown).
