Title: Improvements in furnace regulators
IPC: F23N1/02
Filed: 1927-08-17
Abstract: 276,977. Roucka., E. Sept. 1, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Regulating combustion.-In a furnace regulator employing a servo-motor, and in which the primary value which operates the regulator, such as the drop in steam pressure, varies as the square of the load, an " approximately quadratically acting return gear " is employed to control the movements of the piston of the servo-motor. In the regulator shown, a change in the boiler pressure acting on a diaphragm 2 unbalances a lever 4 which operates the valve 28 of a servomotor 30 the piston 32 of which controls the fuel, air, or feed water supplies, or the flue gases. Attached to the piston 32 is an arm 33 which, through pivoted links 34, 36, moves a roller 16 along an horizontal track 18. The roller 16 forms the pivot of a lever 12 connected to an arm 14 on the lever 4 and balanced by a spring 20, the movement of the roller causing a re-balancing of the system when the piston 32 has taken up a position corresponding to the boiler pressure. In order to provide for any desired relation between the movements of the roller 16 and piston 32 a roller 40 pivoted on the links 34, 36 is forced by a spring 44 into contact with an exchangeable or variable curved guide surface 42. The system is stated to provide an accurate " quadratic variation " or a slightly deviating one, according to the shape given to the curved guide 42.

Title: Improvements in willows and like machines for opening cotton, wool, and like fibres
IPC: D01G9/00
Filed: 1934-07-25
Abstract: 424,543. Opening cotton, wool, &c. GREENHALGH, R., and GREENHALGH, J., Vulcan Ironworks, Oldham. July 25, 1934, No. 21723. [Class 120 (i)] In a willow or like machine for opening cotton, wool, &c., the fibres, after passing through feed regulating rollers, are caused to pass over a breaker rail l extending across the machine immediately above the grid k and thereby caused to lie in the path of the projections or teeth n<1> on the beating drum n. The rail is provided on its inner face with projecting studs or teeth m with which the projections n<1> may mesh, and is adjustable towards and from the drum n. The material is fed to the machine from the lattice a by a system of rollers c, d, i, j in association with the lattice roller b. The bottom feed roller c may be plain, grooved, or fluted, while the grooved or plain roller d is mounted in sliding bearings e spring pressed at g. The ribbed or spiked feeding roller i is similarly mounted in spring-pressed bearings h and the ribbed or vaned roller j is carried on links j<1>. The rollers c, d, i, j are driven by gear wheels from the lattice roller b or by other suitable means and the material on the lattice a is fed forward to the roller j by the rollers h, c, d which prevent the material being drawn in too quickly. The roller j directs the material downwards over the breaker rail l and after passing over the edge of the rail it is opened by the rapidly moving teeth n<1>. If desired, the rail may be solid instead of hollow and of other section than rectangular, while the teeth m may be omitted. The arrangement of feeding rollers described in Specification 396,176 may alternatively be adopted.

Title: Improvements in or relating to the control of internal combustion engines
IPC: F02D1/00
Filed: 1924-09-15
Abstract: 235,756. Vickers, Ltd., and Rabbidge, W. F. Sept. 15, 1924. Regulating.-The action of the governor in adjusting the fuel-injection valve is varied according to the speed for which the governor is set, The range of adjustment of the moment and duration of opening of the valve being reduced as the speed for which the governor is set is less. In the form shown in Fig. 1, the governor E is set by means of a hand wheel F operating rack-and-pinion gear f<1>. At the same time, worm gearing G, by means of a link g', varies the leverage of a bell crank J through which the governor adjusts the eccentric pivot c of the fuel-injection valve by means of links e, j<1>, H. In a modification, the governor actuates the bell crank J through a servomotor. In both of these forms, the action of the governor on the usual fuel-pump control gear K is not altered by the hand setting of the governor. In the form shown in Fig. 3, however, in which the setting of the governor varies the leverage through which the governor acts on the servomotor to adjust both valve and pump, compensating-means is provided to maintain the control of the pump the same for all settings of the governor. The governor E actuates the valve l<3> of the servomotor L<1> through linkages e, p<3>, P and a lever O, the leverage of which is varied by the setting- gear F, f<2> and an arm g<2> which moves the rod g<3> of the servomotor valve along a slot o<2> in the lever O. The servomotor is provided with hunting gear which ensures a movement of its piston proportional to the valve movement. The servomotor piston adjusts the valve gear C by connections m\ m<2>, m<3>, J<1>, H, and the fuel-pump control K<1> by connections m<1>, m, k<1>, k<2>. The compensation for the fuel-pump control is obtained by connecting an arm g<4> on the setting- gear to the link m so as to adjust this along a slot k in the lever k<1> in the sense which counteracts the adjustment in the slot o<2>.

Title: Improvements relating to electrical relays
IPC: H01H51/22
Filed: 1947-08-08
Abstract: 625,541. Electromagnetic switches. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Aug. 8, 1947, No. 21857. Convention date. March 21, 1942. [Class 38(v)] A polar relay, the polarized armature 9 of which moves one way or the other according to the direction of current in a winding 15 on a core 1, has a neutral armature 4 responsive to the presence or absence of current in the winding 15 and a permanent magnet 5, 6 connected, intermediate its ends, with the core 1. When the direction of current in the winding 15 is reversed, e.g. by a pole changer P, the flux in the core 1 will pass through zero causing the release of the armature 4 which is pivoted at 4a on the pole 3 of the core 1. Owing to the air gap between the parts 2, 4 the pole 3 now becomes strongly of south polarity, as does the armature 9 pivoted at 9a to it so that the armature 9 is respectively attracted and repelled by poles 11, 10 of the permanent magnet and tilts into its other position operating contacts 14. With the rise of current in the winding 15 after passing zero, the armature 4 picks up again. An additional winding 18 may also be arranged as shown. This normally assists winding 15 but when the current in winding 15 is reversed, it opposes it so that armature 4 is released. Armature a then operates as before but also operates a pole changer that reverses current in winding 18 so that this now assists winding 15 and armature 4 picks up. Should armature 9 not reverse armature 4 will remain released.
