Abstract: 126,791. Chapman, G. J., Lewis, R. A., and Indented Bar & Concrete Engineering Co. May 15, 1918. Bodies. - A reinforced-concrete wagon or like vehicle is constructed by arranging a skeleton framework of rods forming the side, end, and central beams of the floor, the vertical ribs of the sides, and, where provided, the longitudinal and transverse beams of the roof, thus forming a series of rectangular openings, into which are placed a number of reinforced-concrete panels having projecting wires or strips to engage with the rods of the skeleton framework, the panels being secured in place by further concrete which is run into moulds so as to joint adjacent panels and at the same time to complete the beams and ribs of the wagon &c. Figs. 1 and 3 illustrate the floor of a wagon in which the skeleton framework comprises rods 5, 6 forming the side beams 1, rods 7 forming the end beams 2, rods 4<a> forming the longitudinal central beams 4, and rods 9 forming the transverse beams 3. The panels 11 which are arranged in the openings are made by arranging wires 11<a>, Fig. 11, across slits 12<a> in a mould 12, Fig. 13, and then running in concrete, the projecting portions of the wires being subsequently bent round the rods 4<a>, 5, 6, 7, 9 of the skeleton framework. The panels are joined and the beams formed in concrete by a series of moulds 14, Fig. 10, which are held between boards 18 supporting the panels, and into which concrete is run so as to embed the rods 4<a> of the skeleton framework. In a similar manner the longitudinal rods 11<a>, Fig. 12, and the vertical rods 22a and 22<b>, Fig. 8, of the sides are integral with or are hooked or bent round the rods 5, 6 of the floor; and the sides completed by the panels and subsequent moulding. In the case of an open wagon a top flange may be formed on the sides by running concrete into a mould formed of boards 18, 19 so as to embed wires 16, 17. In the case of a covered wagon the roof would be formed similarly to the floor and sides.

Filed: 1965-02-26
Abstract: 1,034,459. Gating circuits; telephone systems. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1965, No. 8353/65. Headings H3T and H4K. A speech gate between time-division multiplex highways comprises a transistor VT2, the base switching circuit of which, normally biased to cut-off over diodes D1, D2, has a catching diode D4 so that when a switching pulse is applied to the base the transistor only just conducts. By this means the voltage swing on the base is restricted with consequent reduction of charge-discharge currents of stray capacitance of the highways. The resistor R3 limits highway current and damps oscillation. The circuit may employ a PNP transistor, as shown, or an NPN transistor. The gates are arranged in a matrix to give selective access between one set of highways and another.

Abstract: 492,892. Feeding separate like articles in succession. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) March 23, 1937, No. 8451. [Class 117] [Also in Group VII] A machine for rendering leather sole-blanks flexible comprises a pair of endless chains carrying gripping devices which drag each blank in turn between opposed bending rollers. Automatic feeding devices feed the blanks in timed relation to the travel of the chains. A pile of blanks S is inserted in a magazine M while this is tilted about a pivot 200 so that its front wall 204 is horizontal and a gravity follower 212 is retracted. The front wall has a slot for the ejection of the lowest blank, which slot is normally closed by a spring gate 218 with a bevelled lower edge pushed up by an advancing sole. Below the magazine is a guide 228 for a slide 230 itself carrying two slides 232, 234, the first linked to a cam-actuated arm 252 and the second carrying a pawl 262 projecting through a slot in the bottom of the magazine to engage the rear edge of the lowest blank, and yieldable counterclockwise against a spring. The slide 230 is urged towards a stop 242 by a spring 240, but has a stop 243 engaged by the slide 232. The slide 234 co-operates with a stop 256 on the slide 230 and also carries a roll 272, carried in a cage 274 having apartprojectingto the left of the slide and urged to the left by a spring. The roll co-operates with an inclined surface above it. The slide 234 is urged to the left by a spring 270. As the slide 232 moves to the left, the slide 230 moves to the stop 240 and the cage 274 is then engaged by the slide 232 to free the roll 272 and move the pawl 262 beyond the end of the lowest work-piece in the magazine. On the feeding movement of the slide 232, the slide 234 follows until it is stopped by the pawl 262 engaging the work-piece, at which point the slide 232 leaves the cage 272 and the slide 234 is locked to the slide 230. When the slide 232 reaches the stop 243, all three slides move to the left together, to feed the work-piece to the jaws 44, 46. The jaw 46 is opened to release the work by a fixed cam 55.
