Title: An electrical system for a stepwise control of a plurality of drives
IPC: B60L15/32
Filed: 1959-02-26
Abstract: 892,894. Electric selective signalling systems. ELEKTRO-MECHANIK G.m.b.H. Feb. 26, 1959 [Feb. 27, 1958], No. 6692/59. Class 40 (1). In a system for controlling the position of a shaft driven by a motor 22, Fig. 1, each depression of a button 11 advances the shaft by one step and each depression of a button 12 backs the shaft by one step. A button 13 is also provided which returns to the shaft to its reference position in one single operation. The desired position of the output shaft is determined by counting, algebraically, the depressions of buttons 11, 12 on a counter 17 comprising relays A, B ... K. This counter being such that after one depression of button 11 the single relay pair A, B are picked-up, after two depressions the two pairs A, B and C, D are picked-up, and so on, and selecting, by the contacts of relays A, C, E ... J, a corresponding voltage from a potential divider chain of resistors I, II ... VI which is applied via a line 19 to a comparator 24. The other input of the comparator comes from a further and similar potential divider the tapping point being selected by a drum 21 driven by the output shaft. Lack of agreement of the two voltages applied to the comparator drives the motor either forwards or backwards via relays 25. In a modification the two potential dividers are replaced by an arrangement of contacts.

Abstract: 1485412 Gas turbine engine fuel systems ROLLS-ROYCE (1971) Ltd 27 Jan 1975 [15 Feb 1974] 7037/74 Heading F1G In a gas turbine engine fuel system comprising a variable displacement pump in duct means leading from a fuel reservoir to burners, further duct means for conveying fuel from the duct means downstream of the pump to an engine accessory, and means for preventing or permitting the passage of fuel to the accessory, the pump displacement is varied in accordance with a reference pressure in the duct means whereby the displacement is increased when the passage of fuel to the accessory causes the reference pressure to decrease below a predetermined level. Fuel is supplied to pilot burners 28 from a reservoir 10 via a backing pump 12 and a swash-plate pump 16. The pressure rise across the pump 16 is applied to a piston 58 in opposition to the action of a spring 66, the piston being connected via a lever 84 to the pump swash-plate which is normally in the position of minimum flow, any excess flow being spilled by a spill valve 44 which opens when the pump discharge pressure exceeds the required value. Demand for fuel as hydraulic fluid for operating the hydraulic rams 70 of the variable area jet nozzle 68 tends to cause a drop in pump discharge pressure, leading to a drop in any spill flow through the spill valve 44 and, at a predetermined value of the pressure rise across the pump 16, movement of the piston 58 to increase the pump flow, whereby change in pilot burner flow is minimized.

Filed: 1916-05-17
Abstract: 100,493. Barbet et fils et Cie, E. Sept. 5, 1913, [Convention datej. Hydrocarbons, distilling; column stills.-In the continuous distillation of heavy oils which have been used for washing coke-oven gases &c., the benzols are distilled by indirect heat and the vapours are fractionated, and the residues from which the benzols have been removed are treated with live steam in order to distil the naphthalene. The oils after passing through preheaters A, C, B enter a column D, where the benzols are distilled by means of steam coils arranged on the lower plates E. The oils freed from benzols then flow into a column F, where the naphthalene is distilled by an injection of superheated steam. The napthalene vapours are condensed to a liquid in a condenser C, which serves also as a preheater, and the residues pass to the preheater B, A. The benzol vapours are led to a rectifying- column H surmounted by an ordinary reflux device K, L. Carbon disulphide and like volatile impurities issue from the cooler L by a pipe 18, and benzol fractions (benzene, toluene, xylol, &c.) are collected from the column H by pipes 19, 20, 21, 22. The pipe 22 is provided with branches 23, 24, whereby the heaviest fraction may be returned to the still F or may be led to the pipe conveying liquid naphthalene from the condensers C, instead of being collected separately. The distilling-column D comprises, in addition to the lower plates E fitted with steam coils, a number of ordinary plates with hoods, and a top plate acting as a reservoir. The residual heavy oil issuing from the preheater A is cooled by direct contact with a counter-current of water in a cooler G filled with quartz.
