Abstract: 1,166,306. Electric selective signalling systems. GENERAL SIGNAL CORP. 18 Oct., 1967 [20 Oct., 1966], No. 47495/67. Heading G4H. [Also in Division H3] Signals of the kind in which each n-bit signal has a fixed number of bits of one state are checked by a circuit which indicates any signal not having that fixed number. Received serial data in two out of five code is stored at 11 and passed in parallel form to resistors 19, 17 so that the potential at the base of Q 2  varies with the number of Mark bits in the signal. Transistor Q 1  is D.C. biased so that Q 2  is saturated or cut off if the base potential of Q 2  is not equal to that corresponding to two Mark bits in the signal. Q 1 , Q 2  are held inoperative by Q 3  until the end of a signal. If the signal is correct Q 1 , Q 2  pass an alternating signal, from unit 14, which is rectified at 22 and energizes relays IR-5R in accordance with the signal stored at 11. The alternating signal will not be passed to the rectifier if either Q 1  or Q 2  fails.

Filed: 1971-10-18
Abstract: 1363709 Operating hatch covers MACGREGOR INTERNATIONAL S A 18 Oct 1971 [16 Oct 1970] 48278/71 Heading E2M The initial lateral movement of a hatch cover 1 from its closed position is achieved by the engagement of a driven pinion 13 with a short rack 7 which is mounted on the outside of the cover. Only after this initial movement is the normal internal rack 5 engaged by a driven pinion 14. The arrangement allows the internal rack to terminate short of the cover packing 4 so that the two do not interfere with each other. After the initial movement, the rack 7 is free of the pinion 13 and of a cooperating roller 16 so that a spring (10), Fig. 5 (not shown), can pivot the rack about a pin 8 to lie against the cover. On return movement of the cover, the rack 7 is extended by its cooperation with its roller and pinion. The teeth of the rack 7 are vertically extended at its outer end, Fig. 5 (not shown), so that when the cover is lowered in its closed position to its sealing position, the pinion 13 remains in engagement with the rack. As illustrated, the pinions 13 and 14 are driven in train from a single motor 12, but in a modification (not shown) they may be driven by different motors.

In a shuttleless loom for weaving fabric having weft omitted at intervals, e.g. to form warp fringes between successive terry towels, a control mechanism employing a perforated tape puts out of action the weft stop motion and the weft presenter which depresses the weft into the path of the weft inserting needle. The fringe is thereby produced without interrupting the drive of the weft inserters or the cloth take-up. The weft inserters may be mounted on flexible tapes as described in Specification 693485, and the control mechanism may be as described in Specification 1081060.

The plates 25 carry trunnions engaging bearings carried by adjustable members 41a so as to lie in the same vertical plane as the lower edge of adjustable sealing scraper 33. The platform 15 can be tilted about the trunnions by hydraulic cylinders 23 so that the charging plate 31 is tilted while the distance between scraper 33 and plate 31 remains constant. A number of charging plates may be arranged across the width of a glass furnace, the supply shoots 13 being controlled by independent gates 14. The plate 31 is driven from a motor 45 by an eccentric linkage 51, 52, 53, and the shaft 50 of the eccentric drive carries a cam operating changeover valves so that the inclination of the plate 31 is charged during its cycle, so that the acting of its water-cooled lip 32 and the distribution of material is controlled. In a modification, the reciprocating charge plate 60 is mounted on a frame reciprocably mounted on a tiltable platform. The charge plate 60 has slotted lugs 73 at its rear corners engaging rollers 74 on the frame, and is swivelled with respect to the frame by pressure cylinders 80. The front of the plate 60 has wear plates 87 resting on heat resistant balls 85 housed in extensions of the frame. The operation of the cylinders 80 and hence the transverse movement of the charging plate is controlled by a cam on the shaft of the eccentric drive for the frame.
