Title: Improvements in or relating to aviation jet propulsion engines
IPC: F02C7/22
Filed: 1958-03-28
Abstract: 842,286. Automatic control systems for gas turbines. SHEPHERD, G. R. (Westinghouse Electric International Co.). March 28, 1958, No. 10026/58. Class 38 (4). [Also in Group XXVI] In a gas turbine jet-propulsion plant in which additional fuel is burnt in the turbine exhaust gases before entering the propulsion nozzle, the additional fuel is controlled by primary control means combined with secondary control means including a valve which modifies the fuel flow in response to changes in the temperature drop between the temperatures just upstream and just downstream of the additional fuel injecting means. A gas turbine jet-propulsion engine 10 has an after-burner or reheat chamber 20 to which fuel is supplied by nozzles 27 attached to fuel manifolds 25, 26. A flame-holder 28 is provided downstream of the nozzles 27. The fuel supply to the nozzles 27 is controlled by a unit 33 which, as shown, meters the fuel supply in response to changes of compressor discharge pressure but which may be any engine operating condition. A by-pass conduit 36 has a control valve 37 which is regulated by a control unit 41 in response to the difference in temperature between the temperature-sensitive elements 39, 40. The element 40 detects the temperature of the turbine exhaust gases before they are modified in the after-burner and is arranged in the gas flow before the manifolds 25, 26. The element 39 is disposed between the fuel nozzles 27 and flame-holder 28 and the exact position is not critical but it should be sufficiently spaced from the nozzles 27 to ensure that substantially all the fuel is vaporized. In a typical arrangement the element is spaced 10 to 20 inches downstream of the nozzles 27. In a modification, Fig. 2 (not shown), the primary fuel is controlled so as to maintain the turbine exhaust gas temperature constant. The by-pass valve is then only controlled by the temperaturesensitive element 39.

Title: New or improved current sensitive switches and electric appliances embodying such switches
Inventor: BACON JAMES LAURENCE
IPC: H01H83/12
Filed: 1957-03-28
Abstract: 818,805. Thermal switches. MORPHY. RICHARDS Ltd. March 28, 1958 [March 28, 1957], No. 10175/57. Class 38 (5). In a switch similar to that of Specification 727,022, the slow response member is arranged eventually to prevent movement of a part controlled by the fast response member between positions in which that part permits and prevents the slow response member to connect the ancillary circuit to the supply. As shown, the slow response member is a bi-metal 2 secured at its right-hand end to a member 4 carrying a contact 7 and mounted by a leaf spring 5 which biases the left-hand end of the bi-metal against the base 1. The member 2 carries a heater 24 connected to a terminal 25 and to a member 10 carrying by means of a leaf spring 11 a lever 12 to which is fixed one end of a hot wire 14, the other end of which is adjustably mounted at 15. When a low voltage is applied, the bi-metal 2 arches downwardly, thereby engaging contact 7 with a fixed contact 8 to energize the ancillary heater. The bimetal 2 and member 4 carry opposed lugs 20, 22 which when the contacts 7, 8 close are moved sufficiently close together to prevent the lever 12 from passing therebetween. If, however, a high voltage is applied, the hot wire 14 rapidly moves the lever 12 to the right, Fig. 3, before the contacts 7, 8 can engage, thereby preventing the members 2, 4 from moving close enough together to close them. Whether or not contacts 7, 8 close, the bi-metal eventually bends sufficiently to close contacts 26, 27 to short out the hot wire and the heater 24, the heat from the sole plate of an iron with which the switch may be used, being sufficient to maintain the bimetal flexed.

Abstract: 1,135,836. Stress computer. MACHINNOELEKTROTECHNITCHESKI INSTITUT. 9 March, 1966, No. 10439/66. Heading G4G. An apparatus for measuring the magnitudes and directions of the principal stresses at a point of the surface of a body stressed by static or dynamic loading comprises plural modulators M 1 , M 2 , M 3  which convert strain signals, received from electric strain gauges operating at the point in the body, into corresponding sinusoidal amplitude-modulated signals, the latter being applied to a combination of selectively interconnected analogue containing units A, B, C, D, E, F and G. These units are such that input signals x, y applied to them produce functions a i x + b i y from units A and E; c i x - d i y from units B, C and D; (x<SP>2</SP> + y<SP>2</SP>)<SP>¢</SP> from unit F, and arc tg (x/y} from unit G, where a i , b i , c i , d i  are constants which may be varied as appropriate. The strain gauges may be arranged in standard rectangular or delta rosettes producing strain signals E 1 , E 2 , E 3 , applied to the circuits of Figs. 3(a), 3(b) or alternatively in a T-delta rosette which produces a further strain signal E 4  and requires a further modulator (M 4 ) (Fig. 3 (c), not shown).

Title: Improvements in and relating to the electrical purification of gases
IPC: B03C3/30
Filed: 1929-04-05
Abstract: 309,149. Bartling, F., (Assignee of Lawaczeck, F.). April 5, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 6, 1929]. Gases and vapours, treating electrically.-In apparatus for separating dust &c. from gases, the gas is caused to follow a high velocity, for example twenty metres per second, in a relatively thin layer (a few inches thick) between smooth substantially parallel stationary or moving electrodes the collecting surfaces of which are kept clean owing to the velocity of the current. In order to prevent separated dust &c. from being retained with the purified gas owing to the velocity of flow, the purified gas is caused to change direction abruptly or catchment devices are provided to collect the layer of gas in contiguity to the collecting electrode an'd separate it from the bulk of the purified gas. Friction of the flowing gases may produce the necessary electric charge. In the arrangement shown in Fig. 1, gas to be purified is delivered by a pipe 3 into a space 9 between an electrically charged collecting electrode 2 and a rotating disc 1 in which are openings 4 through which purified gas passes to the outlet 5. The dust falls from the edge of the electrode into a hopper 6 when it is discharged by a rotatable valve 7. The disc 1 may be non-rotatable and may act as an emitting electrode. In the apparatus shown in Fig. 3 the gas passes between electrodes 27 and the purified part thereof issues through flared catchment nozzle 19 into pipes 20. The layers of gas in contiguity to the electrodes are received in slots 22 and pass into conduits 23 whence the gas may be returned to the apparatus for the treatment. The dust collected in the electrodes falls into hopper.
