Title: Machine and method for producing knit-goods with a pile or loop-pile surface
IPC: D04B15/32
Filed: 1974-08-22
Abstract: 1479368 Knitting machines; knitted pile fabrics SULZER MORAT GmbH 22 Aug 1974 [31 Aug 1973] 36996/74 Headings D1C and D1K Each feed of a circular knitting machine adapted to produce pile fabric comprises a patterning mechanism 11 for selecting needles 17 to be lifted (on to a cam 13) to take up a pile thread or pile fibres, a feed point 39 for a ground thread and an adjustable knocking- over cam segment 15 such that for knitting a patterned pile fabric respective pile fibres or threads of different colours are fed at successive feeds to the various selected needles (non- selected needles passing at each feed along a miss 25 or tuck cam track) and the cam segments 15 of all but the last feed are raised to inoperative positions while that of the last feed occupies the knit position shown so that all needles take up ground thread and knit at this feed only, thereby avoiding the formation of bare patches having ground fabric only. Each segment 15 is mounted on a slide 51 urged upwards, together with a slide 57 carrying a guide cam segment 45, by a spring 61. A cam 63 engages the slide 51, being held in place against spring 85, 86 force by a lever engaging in a space 77, and controls stitch length in accordance with a setting means 65 provided with a dial 67. Removal of the lever frees the slide for movement to the inoperative position under the action of the spring 61 and of a further lever. As well as setting the cam segments 15 to inoperative position, the ground yarn feeders may be moved to inoperative position at the appropriate feeds. As shown in Fig. 5 cam segments 105 controlling sinkers 99 are moved to inoperative positions (broken lines) by deflector levers 101 at such feeds of the machine. The cams segments 15, 45, 105 may be automatically controlled by electromagnets or piston-cylinder devices.

Title: Improved vehicle brake
IPC: F16D65/08
Filed: 1959-11-02
Abstract: 862,358. Internal shoe-drum brakes. GENERAL MOTORS CORPORATION. Nov. 2, 1959 [Nov. 28, 1958], No. 37097/59. Class 103 (1). In a vehical self-energising brake in which the lining of the secondary brake shoe 20 have a coefficient of friction less than that of the primary brake shoe 15, the leather shoe has lining elements the coefficient of friction of which increases in the direction of rotation of the drum, i.e. the coefficient of friction for the set 41 is greater than that for the set 36. The brake linings consist mainly of sintered ferrous friction material, preferably having between 20% and 30% by weight of graphite. The effect on the noise level of the greater engagement pressure of the secondary brake shoe is counteracted by its lower coefficient of friction. Conversely the lower potential braking power of the primary shoe, due to its lower engagement pressure is counteracted by the higher coefficient of friction of its lining. In this way the optimum braking power for a given noise level is obtainable. Specifications 807,776 and 807,909 are referred to.

Title: A method of accurately mounting the wheelsets in the frame of a railway vehicle bogie
IPC: B61F5/32
Filed: 1965-08-31
Abstract: 1,124,790. Mounting axles; axle box guides. MASCHINENFABRIK AUGSBURG-NURNBURG A.G. 31 Aug., 1965 [29 Aug., 1964], No. 37249/65. Heading B7L. Relates to a method of accurately mounting a wheel-set in correct alignment on a railway vehicle bogie 1 in which each axle bearing casing 22, Fig. 1, is connected through rubber joints 25 and fore and aft longitudinally extending leaf spring links 19 to the frame of the bogie 1 and a helical or rubber spring 17 is interposed directly between the top of the casing 22 and the frame 1. The spring 17 is first prestressed by means of a nut 18, Fig. 4, engaging a threaded portion of a guide device 12. The latter comprises a flange 13 welded to the bogie side frame 2 and having a depending sleeve 11 to receive an upstanding tube 16 whose upper end is threaded to receive the nut 18. The tube 16 is welded to a plate 15 to be mounted on the casing 22 and subsequently securable thereto by a bolt 40 passing through the tube 16 and engaging an internally threaded boss 23 on the casing 22. The frame 1 and the prestressed spring 17 are then lowered onto the casing 22 and secured thereto by the bolt 40, elongated transversely extending serrations 26 on the outer ends of the links 19 at this time slidingly engaging complementary serrations 8 on plates 7 welded to brackets 4, 5, depending from the side frame 2.

Title: Electronic musical instruments
IPC: G10H1/22
Filed: 1966-08-22
Abstract: 1,114,500. Gating circuits. WURLITZER CO. 22 Aug., 1966 [30 Aug., 1966], No. 37555/66. Heading H3P. [Also in Division G5] A latching circuit in a key-controlled instrument comprises gas tubes biased for bi-stable operation and so connected that closure of a key or pedal switch sets a corresponding gas tube and resets any previously fired gas tube. In the electrophonic organ shown neon bulbs 58 are biased for bi-stable operation by a potential divider 70. When any one of switches 86 operated by the keys or pedals is closed, the corresponding neon bulb 58 is connected directly to the top of the potential divider 70. This switches to conduction a corresponding diode 34, thus gating a corresponding tone from a square wave generator 28 to a common line 36 leading to the amplifier 44. The conduction of the switched neon bulb causes a surge through a capacitor 84, dropping the potential at a tap 74 and thus at 68 so as to momentarily reduce the potential on line 64 to a level at which any previously fired neon is cut off. Immediately following closure of a switch 86, a corresponding switch 90 closes applying a potential through a line 106 to the amplifier which responds to gate the tone signals to a loud-speaker 46. A capacitor 108 temporarily supplies a sustaining potential when the switches are released. Thus each tone is sounded for a predetermined period or until another key is depressed. In a modification (Fig. 4, not shown), A.C. tone generators are employed and the gating signal to the amplifier is supplied through a diode controlled by a normally conducting pair of neon bulbs connected to the diode by a transistor operating as an amplifier inverter, the surge through the capacitor 84 being used to cut off the neons. In a further modification (Fig. 3, not shown) a transistor switch responsive to the output on line 36 connects a charging potential to a storage capacitor which provides the gating potential.
