IPC: F02K3/00
Abstract: 1,050,708. Speed governors. ROLLS-ROYCE Ltd. April 2, 1965, No.14176/65. Heading G3B. [Also in Division F1] A proportional governor controlling spill fuel flow in accordance with the rotational speed of a gas turbine has a droop speed characteristic providing a substantially constant degree of stability at varying conditions of load and speed due to the provision in a spill valve 64 of parts 74 of varying cross-section and of a cam connection 101, 102 between the turbine speed control and the governor loading spring 91. Three flyweights 60 act on the spill valve through a thrust block 63 and are driven by a shaft 56 which also rotates the spill valve through epicyclic gearing 66, 67, 70 to prevent sticking. Fuel leaves the valve by way of parts 75 and an annular passage 76 leading to the fuel reservoir and also passes through parts 82, 83 to a space 84 and through parts 85 to a space at the left hand side of a piston 80 to provide pressure balancing. The cam connection 101, 102 rotates a spring abutment plate 87 about a bearing 86 to alter both the leverage and compression of the spring 91 with manual changes in speed setting. A non- return valve 72 is provided in the fuel supply line to the governor which may be driven through a gear-box from the three turbines of a ground effect aircraft having three fixed pitch lift fans and three variable pitch propulsion propellers. Each turbine has a low pressure compressor and turbine mounted on a shaft coaxial with a hollow shaft carrying a high pressure compressor and turbine; separate governors control the top speeds of the shafts by operation through a common ram of a bleed valve for the low pressure compressor. A fuel supply unit for each turbine receives its supply from a fuel pump, a filter, a backing pump and a heater and may be controlled by speed, compressor pressure and temperature.

Abstract: 1,052,531. Making book covers. SMYTH EUROPEA S.p.A. Jan. 3, 1964 [May 10, 1963], No. 334/64. Heading B6A. [Also in Division F2] A machine for manufacturing book covers including means for feeding a lining sheet past a gluing roller and depositing it on a platform and a vertical shaft carrying at least one suction head which is rotated to transfer paper board lengths and a back portion from a squaring station to the platform, is characterized in that vibrations set up in the shaft driving rotation are dampened by an hydraulic brake which sets up a torque to oppose rotation of the shaft. The shaft 41 carries two arms 79 supporting suction heads 82. The shaft is rotatable about a vertical axis and is moved axially in upper and lower holders 52 and 42 (not shown) by a camoperated bell-crank lever 48. A sleeve 57 loosely mounted on the shaft 41 is rotatably mounted in the upper holder 52. The lower end of the sleeve extends below the holder 52 and carries a gear-wheel 63 which co-operates with a reciprocating rack 64. A cross-member 72, keyed to the shaft 41, supports a peg 73. When the shaft is fully lifted, the peg engages one of a pair of apertures 74 in the gear-wheel 63, whereby the shaft is intermittently rotated through 180 degrees in one direction only by the rack 64. The hydraulic brake comprises a chamber 58 between the holder 52, sleeve 57 and lugs 61 and 62. The chamber is oil-filled and in a circuit with non-return valves 92 and 97, and a throttle valve 96. The sleeve carries a vane 59 so that movement in a clockwise sense forces the oil in direction 103 past non-return valve 97 and throttle valve 96, while movement in the opposite sense forces the oil in direction 102 past non-return valve 92. Movement of the oil in direction 102 encounters a lower resistance and corresponds to the interval when the shaft is disengaged from the gear wheel.

Abstract: 1,053,389. Frequency discriminators. AGA A.B. Dec. 31, 1963 [Jan. 25, 1963]. No. 51319/63. Heading H3A. A method of determining the frequency of a signal comprises deriving a phase quadrature signal from the signal, differentiating the two signals, multiplying in modulators each signal by the differential of the other and finally sub- - tracting the modulation products to produce a voltage proportional to the frequency of the signal. The signal whose frequency is to be measured may be used directly, Fig. 1 (not shown), or alternatively it may be heterodyned with a standard frequency and the measurement made on the beat frequency, Fig. 2 (not shown). For low frequency signals, the signal and quadrature signal are modulated on to a carrier frequency, Fig. 3 (not shown).

The stops are required to consist of at least one inwardly extending integral projection 54 on the outer tube 36 spaced from the inner end thereof, and the outwardly flared inner end 56 of the inner tube 42. The inner end of the outer tube 36.is of reduced diameter to form (Fig. 3, not shown) or retain a bearing for the inner tube 42. The tubes may be held in any position by releasing a helical torsion spring 66 housed in the annular space between the tubes into frictional engagement with the inner tube 42. One end 68 of the torsion spring is anchored to the outer tube 36, and the other 70 passes through a slot (72, Fig. 5, not shown) in the outer tube 36 and through an opening (74) in a sleeve 76 which surrounds the outer tube. Thus, rotation of the sleeve 76 in one direction unwinds the torsion spring 66 which releases its frictional grip on the inner tube and allows compression and extension of the unit.

The mould has two side halves 9 and 10, a top section 11 and a slipper portion 12. It is assembled and placed on a slide track 19 and moved into a cradle 21 where the sections are clamped together by pneumatic, hydraulic or mechanical means (Fig. 2). It may then be tilted about a pivot 24 into the position shown in Fig. 5 (also Fig. 4, not shown), where the front wall 5a is upwardly-presented. The slipper portion 12 has a core 12a and plug 17 provided with a pipe inlet for the slip 23. The top section is provided with a central portion 13 which has an opening 15 for an outlet pipe 22 inserted just below the flushing-rim portion of the cast basin. A plurality of such mould and cradle assemblies may be connected to a common slip feed pipe which pumps slip into the mould until filled and then out through the pipe 22 into a common discharge 28. When the casting has formed the slip discharges through the pipe 23 and air enters through pipe 22 at point 22a. If necessary the mould may be tipped right back and the plug 14 removed to complete the discharge of surplus slip. The mould is then turned upright and dissembled, the central top portion being removed with the unwanted layer of casting formed on it and the cast basin being removed on the slipper portion. The process may be automatically controlled by timers-no details being given.
