Title: A fuel control system for a gas turbine engine
IPC: F02C9/32
Filed: 1970-04-17
Abstract: 1300832 Automatic control systems MOTOREN-UND TURBINEN-UNION MUNCHEN GmbH 17 April 1970 [17 April 1969] 18570/70 Heading G3R [Also in Division F2] An engine comprises compressor 1, combustion chamber 2, and compressor-turbine 3 which is coupled to a pump 9 for delivering fuel to a nozzle 17<SP>1</SP>, the fuel-flow being regulated between maximum and minimum values by a solenoid valve 21 associated with restrictors 14, 15. The coil 24 of the solenoid is connected to a pulse-width controller 27 which functions as an amplifier and comparator and receives signals representing various parameters related to the operation of the turbine. The signals t<SP>1</SP>4, t4, correspond to the actual and nominal values of turbine outlet temperature, while the signals n<SP>1</SP> and n relate to actual and nominal values of the engine speed; and the signal t1 represents compressor intake temperature.  In one arrangement, Fig.2 the fuel enters the chamber 64 of a combined injection and metering element 60 through bores 80, 81, from where it passes into the combustion chamber through slots 74, 75, and orifice 77. The magnet coil 70 is energized by current pulses to enter recess 68 to its fullest extent when maximum fuel-flow is desired. The metering element 71 has a hollow piston 72 co-operating with a stop 85, lifting of the piston being opposed by spring 86 located in recess 69 of magnet core 65. In a further embodiment, the fuel injection mechanism comprises a piston which acts as the armature of a solenoid and co-operates with adjustable stops to define the positions for maximum and minimum fuel flow. A cylindrical housing contains a bush associated with a nozzle and featuring the variable fuel flow slots, Fig.3 (not shown). In another modification, the fuel metering device comprises two coils operating a pistontype armature whose stroke is limited by a pair of cores, one of which is axially adjustable from the exterior of the housing, Fig.4 (not shown). A spool moving in a cylinder has one end forming a pole core protruding into a magnet, the spool being shifted against the action of a biasing spring by energization of a coil. A washer embraces the spool and co-operates with limit stops. A recess in the spool is adapted to form a chamber having mutually off-set openings formed in the side wall of the cylinder. A regulating valve maintains the differential pressure across the metering device, Fig. 8 (not shown).

Title: Hydraulic drive of machine for winding and unwinding flexible filamentary bodies
Inventor: KHAIZERUK EVGENY MEFODIEVICH
IPC: B65H59/38
Filed: 1965-05-03
Abstract: 1,110,013. Tension control means. KIEVSKY ZAVOD "STROIDORMASH". 3 May, 1965, No. 18582/65. Heading DID. The tension in the thread 12 is hydraulically controlled. The spool 11 is rotated by a hydraulic motor 10 fed by a variable capacity pump 1. The pump 1 is initially set at minimum output by a spring biassed piston 3 in a cylinder 2. When the pump 1 is started up it feeds liquid via one of the valves 24, 25 and the cylinder 23 to the cylinder 2 to displace the piston 3 against its spring and so increase the output of the pump 1 to a value that will start up the motor 10 and initiate winding of the thread 12 onto the spool 11. The thread 12 passes under a roller 13 coupled to a housing 14. The housing 14 is biassed downwardly by a spring 15. Acting on the housing 14 in a piston 19 in a cylinder 17. If the tension in the thread 12 increases it raises the roller 13 and thus the housing 14. This permits the piston 19 to rise and the liquid then flows from the cylinder 2 to the cylinder 17 and thus the spring biassed piston 3 is able to move to a setting giving a reduced output of the pump I. This reduces the speed of the motor 10 and thus reduces the tension in the thread 12. If, for some reason, the tension should continue to rise the resulting upward movement of the housing 14 causes a cam 21 to displace a valve assembly in the cylinder 23 in a manner venting line 20 drain line 26 thus reducing still further the pressure on the piston 3. The setting of the cam 21 on the housing 14 is adjustable.

Title: Improvements in or relating to intermittent film feed mechanism for cinematographic projectors
IPC: G03B1/22
Filed: 1956-06-15
Abstract: 812,020. Kinematograph apparatus. SVENSKA AKTIEBOLAGET GASACCUMULATOR. June 15, 1956 [June 15, 1955], No. 18590/56. Class 97(1) In intermittent film feed mechanism a claw reciprocator in the feed direction is engaged with the film only during selected reciprocations, the engagement being controlled by two mutually opposed spring forces one of which is rendered inoperative periodically. As shown in Fig. 1, a ratchet type claw 2 is reciprocated in the direction of film feed and urged downwardly towards the film by a spring not shown. It is also urged upwardly by a stronger spring 4 which engages a finger 2a projecting from the claw so that the claw only engages the film when the spring 4 is depressed by a release lever 8 carried by a shaft 7. For this purpose the shaft 7 also carries a lever 9 operated by lobes 11a of one of a number of rotating cam discs 11. The assembly of discs 11, or the shaft 7, is axially movable to bring a selected disc into co-operation with the lever 9, different discs carrying different numbers of lobes corresponding to different film feed frequencies. Two claws 2 may be provided for feeding the film in opposite directions and the speed change mechanism is then arranged to select which claw is to be operative by causing the release lever 8 to act on the appropriate spring 4. To prevent damage of the lever 9 by pressure against lobes of the adjacent cam disc when the frequency adjustment is operated the sides of the lobes are chamfered or the adjustment mechanism includes pre-loaded springs which prevent the application of excessive force. There is also described a device attachable to the projector to engage the frequency adjustment lever and prodvide for remote operation thereof through a flexible cable. The various frame frequencies provided by the cam discs 11 may include a "zero" frequency. The film winding system shown in Fig. 2 may be provided to accommodate the differing film speeds involved. Each of the spools 20, 22 is capable of being coupled to a motor through a clutch 24, 25 to be driven in a direction to wind film on to the spool Between each spool and the intermittent feed mechanism 21 the film passes over a jockey roller 28b or 29b carried on pivoted arm 28, 29 spring urged in a direction to increase the film loops. Movement of either arm due to increase in the film loop produces, through a screw, relative axial movement of the members of the appropriate clutch to cause it to drive the spool to decrease the loop. Similarly, decrease in the loop releases the clutch,
