Abstract: 458,924. Toothed gearing; positive driving bands and pulleys. BARBER, W. E., and WATTS, H. A., Royal Aircraft Establishment, South Farnborough, Hampshire. May 25, 1935, No. 15325. [Class 80 (i)] Gear members for meshing with a flexible cable with a helical thread comprise two relatively fixed parts, one of which is toothed, slotted, or otherwise form to mesh with the threads at the side of the cable. In the form shown in Figs. 2 and 3, both of the relatively fixed parts 1, 2 are slotted to engage the cable. In a modification, not shown, only one part is slotted. In the form shown in Figs. 5 and 6, the arm 17 is slotted to engage one side of the cable, which runs in a guide 19a while the part 22 passes behind the guide 19 to keep the arm 17 in mesh. The cable may act as a positivedriving band or as a worm. In the form shown in Fig. 2, the teeth 7, 8 of the two parts 1, 2 of the wheel are oppositely inclined. The parts 1, 2 are adjustably secured to a central disc 4 by screws 28 and slots 27. Fixed cover plates 11, 12 carrying guide-pieces 9, 10 are provided for the cable. Two gear-wheels on a common spindle may transmit drive from one cable to another. A cable may also engage a rack with one or more slotted parts similar to those of the gear-wheel described above. Specification 380,204 is referred to.

Title: Television systems and synchronising means therefor
IPC: H04N5/06
Filed: 1940-10-16
Abstract: 542,258. Television. STANDARD TELEPHONES & CABLES, Ltd. Oct. 16, 1940, No. 15336. Convention date, Oct. 19, 1939. [Class 40 (iii)] A television transmitter is adapted to generate a composite synchronizing signal comprising usual unidirectional pulses at line frequency and pulses of high frequency waves at frame frequency. As shown in Fig. 1, unidirectional pulses 24 from a conventional synchronizing generator 10 are fed to a frequency multiplier 11 yielding pulsations 13 at 529-2 k.c. This high frequency 13 is supplied to an amplifier 15 unblocked by pulses 16 at frame frequency from the generator 10, so that the output of this amplifier is a series of pulses 12, each constituted by a short train of high frequency. These pulses 12 and the usual line pulses 14 from the generator 10 are mixed by means of the two valves 35, 3'6 and fed through a cathode load-stage of low impedance 41 to the transmitter 20, which receives the video signal from a cathode-ray tube 29 synchronized and blanked by pulses from the common generator 10. The high frequency train at frame frequency produced by this circuit extends on both sides of the axis and may be clipped by a valve circuit, Fig. 3 (not shown), the negative peaks being first clipped by one valve 42 and the opposite peaks by a subsequent valve 43. A receiver for this television signal is described in Specification 550,631. The Specification as open to inspection under Sect. 91 describes also a receiver circuit generally similar to that described in Specification 542,259 but different in details therefrom. This subjectmatter does not appear in the Specification as accepted.

Abstract: 760,631. Gas turbine plant; Jet propulsion plant. SHEPHERD, G. R. (Westinghouse Electric International Co.). May 26, 1954, No. 15493/54. Claes 110(3). [Also in Group XXIX] A system for controlling the fuel supply to a jet propulsion gas turbine engine 10 during acceleration so as to avoid stalling of the compressor or overheating of the engine comprises an acceleration control valve 47 arranged in the fuel supply pipe between the pump 25 and the combustion apparatus 13 and controlled by a pressure-responsive element such as the evacuated bellows 56, which may be subjected alternatively to the compressor inlet pressure through a pipe 60a or the compressor outlet pressure through a pipe 60b, the change from one pressure to the other being effected by a changeover valve 65 which is opened automatically to expose the pressure-responsive element to the compressor delivery pressure when the engine speed exceeds a predetermined value. An hydraulic actuator 19 for the variable area exhaust nozzle 17 of the engine is operated simultaneously with the change-over valve 65, the nozzle area being reduced to its minimum value when the change-over valve is open. The change-over valve 65 is closed by the energization of a coil 66 in circuit with a coil 20 controlling the actuator 19 and a switch 102, 103 controlled by the speed-responsive mechanism 29. The latter comprises a ported sleeve 76 driven from the engine and within the sleeve a piston valve element 77 position by centrifugal weights 75. The valve element 77 controls the admission pressurised fuel through a control pressure pipe 84 to a piston 91 connected to the movable element 103 of the switch and to an overspeed valve 36 in the fuel supply. At high speeds the pipe 84 is vented through a port 85 and a pipe 43. The valve 36 is arranged in a throttle device 31 also containing a throttle valve 37 having a metering port 40 and a bypass port 42. The valve 37 is operated by an element 38. The acceleration control valve 47 is of the double-seated type and is operated against a spring 53 by a stem 58 connected to the bellows 56. Under the influence of compressor inlet pressure some of the fuel is diverted past the lower valve seat 48 and a passage 49 to the return pipe 43 but when the changeover valve 65 is open, the compressor delivery pressure contracts the bellows 56 and the valve 47 closes on its lower seat 48 so as to allow the fuel to pass entirely to the combustion apparatus 13.

Abstract: 1,059,924. Centrifugally moulding polylactams. POLYMER CORPORATION. April 20, 1964 [April 23, 1963], No. 16275/64. Heading B5A. A method of making a polylactam article, in particular a pipe, comprises feeding a reactive mixture of a lactam, a catalyst and a promoter into a centrifugal mould, applying a centrifugal force by first slowly rocking or rotating the mould, and then, after a rise in viscosity of the mixture has taken place due to polymerization, increasing the speed of rotation. In the embodiment shown, the mixture is fed into a mould 25 from a mixing tank 10 via a fitting 31. The mixture is heated to its polymerization initiation temperature in tank 10 and mould 25 is preferably heated to a similar or slightly higher temperature. The initial rocking or slow rotation of mould 25 is continued until the viscosity of the mixture has risen to a predetermined value, measurable in terms of temperature by means of a thermocouple 40 since the polymerization process is exothermic, and the speed of rotation of the mould is increased e.g. to 1200 r.p.m. Tank 10 may be dispensed with, in which case the mixture may be formed and heated in mould 25. The article is removed from mould 25 by detachment of ends 26, 27 therefrom. Amongst mixture-forming materials mentioned are higher lactams such as epsilon-caprolactam and cyclic hexamethylene adipamide, anionic polymerization catalysts such as alkali and alkaline earth metals or their hydrides, boro-hydrides, oxides, hydroxides, carbonates or Grignard reagent compounds and promoters such as organic isocyanates or N-substituted imides.
