Title: Improvements in or relating to sizing machines
Inventor: NORTON JOHN
IPC: D02H3/00
Filed: 1963-09-20
Abstract: Yarn is wound on to a beam at a varying tension which results in constant yarn density throughout the beam.  Yarn is supplied to the beam at a constant rate and the beam is driven by an infinitely variable gear which has a control shaft whose position varies with the gear and which is coupled to the slides of a potentiometer.  The tension in the yarn is measured by strain gauges whose output is amplified and fed to a comparator where a comparison is made with the output from the potentiometer.  In use, as the beam diameter increases the output from the strain gauges alters, is compared with the output of the potentiometer and the variable speed gear altered to reduce winding speed and tension.  However alteration of the variable speed gear also alters its control shaft which moves the slider of the potentiometer so that the comparison of outputs made is not the same as the first comparison but is a comparison which results in a lesser tension and a constant density.

Abstract: 1,166,544. Spring applied brake actuators. WESTINGHOUSE BREMSEN-UND APPARATEBAU G.m.b.H. 14 Aug., 1967 [26 Oct., 1966], No. 37290/67. Headings F2E and F2F. A " spring applied" brake actuator for vehicles having a piston 10 (Fig. 1) resiliently loaded by a spring 9 which urges the piston and thereby a piston-rod 14 into a brake applied position, and wherein fluid pressure can be applied via a port 13 to exert on the piston a force to overcome the spring 9 and move the piston to a " brake released" position, is characterized in that the piston is selectively coupled to the piston-rod by a locking device which when unlocked allows the brakes to be released manually should the fluid pressure source fail. The locking device includes a sleeve 1 which is slidable on a tube 2 integral with the piston 10, between stops 4 and 7 against a spring bias 3. A plurality of balls 6 are located in holes 5 in the tube 2 which balls are pressed by sleeve 1 into a groove or recess 15 in the piston-rod 14 when in the locked position (as shown on the right of the centre line). By withdrawing the sleeve 1 the balls are released (as shown on the left of the centre line) and the rod 14 can be moved to its " brakes released " position, while the piston is maintained by spring 9 in its " brakes applied position ". In a further embodiment, Fig. 3, the spring applied brake actuator is combined with an air pressure operated service brake actuator, which comprises a diaphragm 22 clamped to form with an end cover 21 a chamber 24 to which air pressure may be applied via a port 23. A chamber formed between diaphragm 22 and the piston 10 is vented to atmosphere at vent 20. The spring 9 in this case bears against a partition 18 as does a spring 28 which urges a diaphragm plate 25 against the diaphragm 22. The maximum length of movement of the service diaphragm is dimension " h " and since the length of groove 15 is greater than " h ", full service brake application can be made without affecting the position of tube 2 and piston 10. To make a spring applied brake application pressure is released from chamber 12 and the piston moves downwards carrying the balls with it until they engage in groove 15 to move the rod; the maximum movement of the piston being " h + x ". In this embodiment the locking device is surrounded by a dust seal 29.

Title: Binary trigger circuit employing single transistor
IPC: H01L29/00
Filed: 1954-12-24
Abstract: 790,404. Transistor two-stable state circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1954 [Dec. 31, 1953], No. 37382/54. Class 40 (6). In a circuit employing a transistor with an auxiliary emitter, input pulses from generator 15 are applied directly to the emitter 1e and over a gate 14 to the auxiliary emitter 1a, the gate being controlled by a connection 13 from the collector 1c. Assuming the transistor to be in the off condition, the collector potential is low and due to the connection 13 the anode of diode 14 is also low. The battery 12 supplies the auxiliary emitter 1a over the resistor 11 and maintains conduction through the base 1b and the potential divider 4, 5 and 6. Diode 14 is thus effectively biased off so that an input positive pulse from generator 15 passes directly to the emitter 1e causing the transistor to pass to the on state. Since the transistor is conducting, the collector potential rises and thus the anode of diode 14. The base 1b becomes negative with respect to earth taking the electrode 1a with it while the emitter 1e is maintained near earth potential by diode 10 conducting. The next positive input pulse passes through diode 14 to electrode 1a taking the base 1b positive, the pulse applied to the emitter 1e being ineffective since the transistor is substantially saturated. The transistor is now cut-off and the circuit restores to its original condition. A capacitor 19 provides a degree of memory, making the component values less critical. Specification 790,403 is referred to.
