Abstract: 972,822. Hump yard systems. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Dec. 7, 1961 [Jan. 25, 1961], No. 2886/61. Heading B7N. [Also in Division H4] A radar transmit-receive arrangement used for determining the speed of cuts of rail vehicles in an automatic hump yard system and comprising klystron oscillator 1, waveguide hybrid 2, aerial 3, demodulator crystal 4 and monitor crystal 5 is tested during standby periods by applying audio frequency signals to the monitor crystal to disturb the hybrid impedance relationships and modulate at audio frequency the signal applied to the demodulator. The demodulator output signals check the functioning of the apparatus. Oscillator 6 provides two test signals of different frequency which are applied alternately to the monitor crystal circuit. The resulting demodulated signals are applied via an amplifier 7 and velocity meter 8, in which they are converted to steady velocity analogue signals, to a speed control unit 9 in which the signals are compared with a standby velocity analogue signal applied to terminal 10. The frequency of the test signals is such that the velocity analogue signals derived therefrom are respectively greater than the standby signal, when the speed control unit supplies an output to energize relay RA and less than the standby signal, when the control unit energizes relay RE. The alternate operation of relays RA and RE maintains an alarm relay B in its energized state.

Filed: 1973-01-19
Abstract: 1415257 Stays; latch devices GIRLING Ltd 20 Dec 1973 [19 Jan 1973] 2982/73 Headings E2A and E2F [Also in Division F2] A piston-cylinder gas spring for fitting between a vehicle body and a tailgate (not shown) is provided with a mechanical latch 4 which operates automatically as the spring nears its fully extended position (corresponding to the tail gate being open) to prevent substantial contraction of the spring should the gas leak away, the latch being manually releasable to allow contraction of the spring (and closing of the tail gate). The latch 4 has an annular portion 12 which fits over the cylinder 1, and resilient arms 13 with abutments 14. When the spring is in its contracted position, a dirt shield 3 is telescoped over the cylinder 1. When the spring is permitted to expand, the dirt shield 3 rides over the arms 13 until it is clear of them. The arms spring out and subsequent contraction of the spring is prevented by the dirt shield 3 engaging the abutments 14, when the spring is to be compressed, the arms 13 are pressed in manually. In Fig. 3 (n.s.), the dirt shield 3 is axially spaced from the abutments 14 of the latch when the gas spring is in its extended position. If the spring fails, the shield will sink till it contacts the abutments, giving a visual indication of failure.

Abstract: 1,216,362. Cutting and folding paper. CHANDLER & PRICE CO. 19 Jan., 1968 [23 Aug., 1967], No. 3071/68. Heading B8R. A cut and folded web is transferred from a drum 1 to a drum 3 with or without a further fold according to the setting of cam means controlling the operation of picker pins on the drums 1 and 3. A paper web P is folded longitudinally between rollers 35 and 36 and then transferred by serrated feed rollers 24 and 28 to a main drum 1. The web is carried past cutting cylinder 2 by picker pins 53 which engage the leading edge. The picker pins are controlled by a movable cam 63 co-operating with follower 61 such that they may be retracted either as the leading edge of the web is transferred to pins 84 on drum 3 without further folding or when the web is transferred to drum 3 by a transverse fold, brought about by blades 37 co-operating with jaws 77. When it is required that the web be transferred to drum 3 without a transverse fold the blades 37 are rendered inoperative and picker pin retracting cam 63 is in the full line position shown and when it is required that the web be transferred to drum 3 by a transverse fold blades 37 are rendered operative and cam 63 is brought to the dotted position (at 90 degrees to the full line position). Cam 95 is movable to effect operation of pins 84 when required (i.e. when there is no fold).

Title: Improvements relating to heilman type combers
IPC: D01G19/14
Filed: 1948-02-03
Abstract: 651,411. Combingmachines. WHITIN MACHINE WORKS. Feb. 3, 1948, No. 3107. Convention date, Nov. 30, 1946. [Class 120 (i)] A Heilmann type comber having a comb cylinder, a reciprocable nipper frame and a rock shaft, includes a front support for the nipper frame comprising a pivoted member movable about a fulcrum located on the comb cylinder side of the path of movement of the nipper frame, and a rear support for the nipper frame comprising a pivoted member movable about a fulcrum located on the side of the said path remote from the comb cylinder. As shown, the nipper frame 7 is supported at the front by rods 8, 9 (not shown), pivoted to the comber frame 10 at 11, and at the rear by depending crank members 16 secured to the rock shaft 1 which thus reciprocates the nipper frame. The oscillation of the rock shaft is utilized also to effect the opening and closing of the nippers. This is done by means of crank extension 23 which has pivoted to it a spring housing 27, the upper end of the spring 28 engages a cap 26 on the upper end of the stem 25, the lower end of which is pivotedly connected to the rear end of lever 17, which carries at its forward end the nipper knife 5. There is a similar mechanism at the other side of the frame. In the retracted position the spring urges the nipper knife 5 against the cushion plate 6. As the crank 16 oscillates to advance the nipper frame, the spring-closed position of the nippers will continue until the housing 27 engages the nut 29, and, in its further movement will rock lever 17 relative to the nipper frame thus causing the nipper knife to rise away from the cushion plate. The return movement of the rock shaft reverses the procedure. The top comb 30 is located in slots in the nipper frame 7 and is vertically adjustable by means of studs 33 which bear against the top of the cross member of the nipper frame.
