Title: Improvements in and relating to electrical servo control systems
IPC: G06F7/68
Filed: 1961-05-09
Abstract: 946,706. Pulse frequency dividing circuits. WARNER & SWASEY CO. May 9, 1961 [July 25, 1960], No. 16826/61. Headings H3P and H3T. [Also in Division G4] A pulse-responsive servo system comprises a source of pulses, the frequency of which is reduced by a frequency divider giving an output of non-uniformly spaced pulses, the separation of which is made more uniform by means of a further frequency divider. As shown in Fig. 3, the output of a pulse generator 10 of frequency 4f is fed to a chain of valve or transistor bi-stable circuits 14a to 14j, each halving the frequency. The outputs of two or more of the bi-stable circuits are superimposed on line 80 under control of a series of AND gates 40 to 49 according to the data stored in a shift register 35. The required ratio of the frequency at line 80 to frequency 4f is fed as a series binary signal from a tape record into line 81 and stepped into the shift register 35 by pulses fed to line 82. It is shown that gates 41, 43 may be opened to provide an output frequency of <SP>5</SP>/ 16  Î 4f or gates 40, 42 may be opened to provide # Î 4f. The pulses in these trains are, however, not uniformly spaced in time, but if the pulses fed to the selected gates have a suitable phase relationship, regularly spaced pulses of frequencies <SP>5</SP>/ 16 f or <SP>3</SP>/ 8 f may be selected by means of a 4: 1 divider 16. Specifications 849,146 and 925,801 are referred to.

Abstract: 1,073,204. Bowden wire transmissions. MORSE INSTRUMENT CO. April 18, 1966 [Aug. 31, 1965], No. 16848/66. Heading B7E. [Also in Division F2] A device giving selective coarse or fine axial control of a Bowden cable core (12) comprises an externally threaded control shaft 26 connected to said core and slidable in a fixed sleeve 24, and a collar 41 movable on the sleeve 24 between a fine control position in which it holds a ball 39, housed in a radial bore of the sleeve 24, in engagement with the control shaft thread so that the control shaft may be screwed relative to the sleeve, and a coarse control position in which the ball 39 is received in a recess 50 of the collar 41 to allow non-rotary axial movement of the control shaft. The collar 41 is retained by a spring clip 58, and in the fine control position shown a wall 40 of the recess 50 is inclined at 7-12 degrees to the tangent 51 of the sleeve 24 at the radius along which the ball 39 moves, to allow the collar 41 to be forced into the coarse control position by a sharp axial blow on the control shaft 26, while remaining firm against vibration. A cylindrical block (28) secured to the end of the cable core (12) is rotatably housed in the end of the control shaft (26) (Fig. 2, not shown), a bearing sleeve (34) on said shaft end being slidable in a tube (19) carried by the sleeve 24, the casing (13) of the cable being secured to the tube (19).

Abstract: 938,553. Generating combustion products under pressure. ROLLS-ROYCE Ltd. May 1, 1962 [May 9, 1961], No. 16886/61. Class 51 (1). Reheat combustion apparatus for a gas turbine engine comprises a jet pipe within which is concentrically mounted an annular manifold, the arrangement being such that in operation a complete or a substantially complete annular stream of turbine exhaust gases flows across the surface of the manifold, means for maintaining the manifold substantially filled with a combustible mixture of air and fuel, the manifold being apertured to permit the combustible mixture to pass out of all parts of the manifold in substantially equal amounts, and combustion stabilizing means adapted to be supplied with the combustible mixture. The reheat equipment is mounted within heat shield 18 and jet pipe 17 and comprises annular manifolds 25 made up of series of sections 26 (Fig. 3), which do not communicate with each other, mounted within V-shaped annular stabilizing gutters 21. Each section 26 has two rings of angularly spaced apertures 27, each aperture 27 of one ring being disposed midway between adjacent apertures in the other ring and aligned with a slot 30 in the upstream wall 22 of the gutter 21, through which turbine exhaust gases flow. A stub pipe 31 open at its upstream end to the turbine exhaust gases communicates with each section 26. Fuel is supplied to pipes 31 through pipes 34 from annular manifold 32. Main fuel annular manifolds 35 are supplied with fuel through pipes 36, each manifold 35 having a ring of angularly spaced apertures 37. In a modification, Fig. 5 (not shown), the annular manifold 25 is mounted upstream of the gutter 21 and both are mounted within an annular member open at its upstream end to the flow of exhaust gases. In a further modification, Fig. 6, gutter sections 21b have flattened stub-pipes 31b communicating with manifold 25b. Fuel is injected on to splash-plates 45 by hypodermic injectors 46. The manifold apertures may have a diameter of 0.080 inch.

Title: Improvements in or relating to Electrical Signal Detection Circuits
IPC: H03K5/153
Filed: 1968-04-10
Abstract: 1,155,168. Transistor pulse circuit; pulse modulation systems. INTERNATIONAL BUSINESS MACHINES CORP. 10 April, 1968 [28 July, 1967], No. 17203/68. Headings H3T and H4L. A circuit for detecting the instant when pulses reach their peak voltage comprises a first circuit 2 (Fig. 5) for storing the peak valve of pulses, a parallel circuit 3, 4 for delaying the pulses and storing the peak valve of the delayed pulses and a comparator 5 which produces an output only when the two stored values are equal. As shown, the output of the comparator is used via transistors 24 to discharge the capacitor 22 of the peak detector 2 and via a variable delay circuit 6 to discharge the capacitor 42 of the peak detector 4, the variable delay being produced by a one shot circuit 65 followed by a circuit which differentiates the trailing edge of its output pulse. In Fig. 2 (not shown), 10 and 11 are the desired pulses and the rest are lower amplitude noise pulses. The output of the undelayed peak detector builds up as at B and the output of the delayed detector as at D. Just before 17 the two outputs are equal and the comparator produces an output 15 which resets the first output at 17 and subsequently the other at 19, equality during resetting being too brief to produce an output. The circuit may be preceded by a digitial switched filter to pass any input pulses corresponding to a desired code and by a self-clocking gate which opens in a region around the expected time of the signal (Figs. 3, 4 and 6, not shown). The circuit is applicable to pulse position modulated signals and the forward delay would be equal to the longest time before an information pulse is expected and the resetting delay less than half the frame period.

The wires are produced by inserting an ingot of Nb 42 wt. per cent Ti in a Cu or Al sheath, electron beam welding two covers to the sheath, and hot pressing and drawing. The resultant rod is cut into appropriate lengths and the Cu sheath removed, e.g. by cutting, the resulting superconductor wires being inserted into bores in a Cu block to which covers are welded. The block is then hot pressed to a rectangular cross-section and then reduced and shaped by multiple cold drawing. In a first arrangement, Fig. 4a, the wires 12 are provided with opposed longitudinal ribs having concave outer faces while the wires 13 are provided with opposed dovetail grooves. Wires of alternate types are assembled together and provided with Cu edge wires 14, 15 to form a strip which is drawn through a die having a rectangular aperture to deform the ribs so that they interlock with the grooves, Fig. 5 (not shown). In an alternative arrangement, Fig. 4b, the wires 17 have dovetail ribs and the wires 18 have rectangular grooves defined between wedge shaped shoulders. After assembling, the strip is rolled to deform the shoulders so that they interlock with the dovetail ribs.
