Abstract: 1,022,258. Gas turbine plant. J. LUCAS (INDUSTRIES) Ltd. Feb. 6, 1964 [Feb. 22, 1963], No. 7198/63. Heading F1G. [Also in Division G3] A gas turbine engine comprises a low-pressure compressor 11 coupled to a turbine 12 by a shaft 13, and a high-pressure compressor 14 coupled to a turbine 15 by a shaft 16 which surrounds the shaft 13. The fuel to burner nozzles 18 is supplied from a reservoir 47 by a swash-plate pump 22, driven from shaft 13 through bevel gears 19, 21. The swash-plate of the pump is positioned by a servo-mechanism 23 responsive to the pressure in a spill-line 31, having a restriction 56, controlled by a valve unit 28. A spindle 27 of the unit 28 is positioned by a fly-weight governor 26 driven from the shaft 13 through bevel gears 19, 24. Movement of the spindle increases the spill flow with increased speed of the shaft 13 by moving a slot 34 so as to connect the spill-line 31 with one or more passages 35 communicating with the delivery from the pump through line 49. The speed of the shafts 13, 16 are sensed by devices 44, 45, the outputs of which are compared in a device 46 to derive an error signal in line 54, representative of the deviation from a desired proportionality between the shaft speeds, which, through a motor 43 and a wormdrive 40, 41, rotates a cam 38 which alters the stressing of a spring 36 opposing movement of the spindle 27. When the shaft 16 reaches a speed proportionally in excess of the shaft 13, the cam 39 is rotated to modify the effect of the governor, so as to restore the proportionality, by reducing the speed of the shaft 13 at which the governor causes a reduction in the fuel flow to the burner nozzles.

Abstract: 1,142,932. Digital data transmission. BUCHUNGSMASCHINENWERK KARL - MARXSTADT VEB. 18 Feb., 1966, No. 7267/66. Heading G4H. The contents of a store 1, Fig. 1, are read out to a mechanical unit, e.g. a printer, by reading out successive storage locations repeatedly by continuous cyclic interrogation, comparing each character in turn with signals representing the angular position of the printing mechanism, and upon agreement, sending a pulse to energize the magnet 71-84 of the printing mechanism corresponding to the storage location being interrogated. The storage locations are selected in turn by a counter 2 which also enables a corresponding gate 31-44 so that when the comparator 20 indicates agreement the associated magnet is energized through an amplifier 51-64 Each location of the store when read out sets a combination of triggers in a register 10, producing signals on mark and space leads A1, #A1 &c. After reading out, the character is reentered in the store. The printing unit produces a signal on one of ten leads indicating the position of the printing member. As soon as agreement is reached the printing member is retained in the appropriate position and the counter 2 is stepped on to the next location. The magnets 71-84 remain energized by a holding circuit. The comparator comprises eight AND gates to which the signals from the store and the printer are applied in appropriate combinations so that when agreement is reached no gate gives an output. Two printers may be connected to the same store working asynchronously. In the form of Fig. 4 (not shown) the printer, e.g. a typewriter which indicates the denomination (and storage location) to be printed. When the location counter (2) indicates the same location the comparator (20A) enables a re-coding circuit (30A) re-coding the corresponding character from the store to energize one of the printing magnets (50A-59A). Instead of a printer the recording device may be a paper tape punch, the recoder (30A) being adapted to give an output in the punched tape code.
