Patent GB-446427-A (GB)
Abstract: 446,427. Knitting. LACEY, W., c /o Trent Engineering Co., Ltd., Wilford Crescent East, Nottingham, WIGFIELD, G., 142, Eltham Road, West Bridgford, Nottinghamshire, and WIGFIELD, S., 59, Loughborough Avenue, Sneinton Dale, and CUCKSON, H. W., 28, Elm Avenue, both in Nottingham. Oct. 30, 1934, No. 31054. [Class 74 (ii)] Striping thread fingers A having their free ends normally disposed below the feeding position, are raised in order to feed the rib needles E, by cams G acting on noses A<2> on the fingers, and, after release by the cams, are retained in the operative position for a time against the action of springs N, by means of catches M, independent mechanism being provided for tripping the catches, so that a distinct interval elapses between the raising of one finger and the lowering of the one previously in action. The whole thread feed assembly is mounted on a bracket C carried on the rotating cylinder needle or sinker cam ring. The cams G are formed as circular plates, one to each thread finger, and have partly severed peripheral parts G<1>, some of which may be broken off leaving the others as cam lifts. A striker plate L may be raised to an operative position by the action of a pattern chain and wheel, so that, each time the thread feed assembly rotates past it, a stud L<1> engages a star wheel K, and rotates the cams to the extent of one portion G<1>, through bevel and other gearing J, J, J<1>, J<2>. A cam incline P, subsequently raises a plunger O, to cause a pin N<2> carried thereby simultaneously to trip all catches M, and so lower that thread finger which is no longer supported by its cam. Thus, if a new thread has been substituted for an old, the two will have been knitted in together during the interval between the movement of cams G, and the action of cam incline P. Movable thread cutting and thread trapping blades Q<1> and Q<3> (not shown) are actuated twice at each thread change to sever and trap the old thread and sever the new thread from the trapper. This is effected by an arm V which follows the suitably contoured inner edge of the plate L, the arm V rotating a shaft S and hence actuating the blades through arm R and link T. The thread is guided to the needles E by a hook-shaped part D<1> on the latch guard.

Abstract: 1,201,646. Signal correlation in photomultiplier. INTERNATIONAL STANDARD ELECTRIC CORP. Oct.2, 1967 [Oct.4, 1966] No.44796/67. Heading G1A. [Also in Division H5] A modulated or varying optical signal is supplied to a photo-multiplier having a photo-cathode at one end, a control grid adjacent and parallel to the photo-cathode and an electron multiplier at the other end, and an electrical signal is applied to the control grid to produce an output which may bear a relation to relative frequencies or phase of the two signals. In a laser target-distance measuring device a laser beam having a time varying flux (pulse or sine wave) is reflected by the target on to the photo-cathode and a portion of the laser beam is converted locally to an electrical signal and applied through a variable delay circuit to the control grid. The delay necessary to give maximum output from the electron multiplier is indicative of target distance. In a second target distance measuring arrangement Fig.2 1500M/C oscillations from a oscillator 38 are applied directly to modulate a light source 14 and through a mixer 40 reducing the frequency to 1490M/C to the photo-multiplier control grid 22. The output in this arrangement is the difference frequency 10m/cs and a distance signal is obtained from it by a phase comparison with the output from 10M/C oscillator 34, and an ambiguity removal circuit 36. In a further application of the photo-multiplier device to determining the luminescent decay time of a phosphor, the phosphor is coated on the face plate of a cathode ray tube and the activitating tube pulse-triggers a second pulse generator which gates the photo-multiplier and this samples the luminescence at intervals. The output is indicated and the entire rise and decay may be recorded.

Abstract: 1522506 Helicopter warning system UNITED TECHNOLOGIES CORP 30 Oct 1975 [18 March 1975] 44871/75 Heading B7W A system for warning the pilot of a helicopter during landing that ground contact of the tail is imminent produces signals which are indicative of the helicopter's pitch angle and altitude, and sums these signals to provide a combined signal which is compared with a predetermined value indicative of ground contact. A visual and/or audio alarm signal is energized only when the voltages and phase of the altitude and pitch signals are equal and opposite. The summer 30 is biased by the output of a rate-ofdescent amplifier 26 so that the altitude signal is shifted upwardly as a function of the rate of descent of the helicopter. An altitude cut-off 28 is provided to prevent the actuation of the warning signal when the helicopter is above a predetermined altitude. An inhibit logic circuit (21) ensures that the warning signal is never actuated when the pitch is below a predetermined angle.
