Abstract: 682,388. Binding edges. SHIMWELL, O., and SHIMWELL, D. W. June 15, 1950. [July 14, 1949; Aug. 26, 1949; Sept. 27, 1949 ; Jan. 23, 1950] Nos. 18579/49, 22207/49, 24755/49 and 1688/50. Class 42 (i). [Also in Group IX] In weaving a succession of bags comprising two layers x, y of fabric interwoven at intervals to form seams, the seams also consist of two layers, so that when the bags are separated by cutting along the seams, the resulting flaps f can be turned back and stuck to the layers x, y. Adhesive may be applied to one or each side of the flaps; or nylon, polythene, or other thermosetting or thermoplastic weft threads may be incorporated in the seams. According to some of the Provisional Specifications, the flaps are not stuck on to the sides of the bags. The first Provisional Specification describes seams of single-ply fabric having adhesive applied to prevent unravelling after cutting. The fourth Provisional Specification describes two-layer seams having one layer of open weave so that a nozzle can be inserted to squirt adhesive between the layers, which are then pressed together and cut along the middle.

Title: Improvements in or relating to impulse circuits for railway axle-counting installations
IPC: B61L1/16
Filed: 1957-06-19
Abstract: 819,234. Counting-apparatus. SIEMENS HALSKE A.G. June 19, 1957 [June 20, 1956], No.19351/57. Class 106 (1). An impulse circuit for a railway axle-counting installation, for producing counting-in and counting-out impulses (at outputs 5, 6 respectively) from pairs of overlapping impulses produced by the successive actuation of switching means by the passing of each axle, includes first and second input terminals 3, 4 for the pairs of impulses, and first and second input gates 1, 2 and output gates 8, 7 each having one input connected to the associated input terminal, each input gate being arranged to pass an impulse only when the other input gate is blocked, and each output gate 7, 8 being arranged to pass an impulse only when the input gate 1, 2 respectively is changed over from the unblocked to the blocked condition. As shown, the input gates 1, 2 are cross-connected by inverting amplifiers 9, 10. A passing axle causes overlapping pulses a, b to be applied to inputs 3, 4; if the pulse a occurs first as indicated, it passes through the corresponding input gate 1 and thus closes via inverter 9 the other input gate 2 to the second pulse b. When the pulse a ends, the output of inverter 9 changes so as to apply a pulse via RC circuit 13, 11 at output gate 7 which is opened by the pulse b at 4 thus producing an output pulse at 5. If an axle passes in the opposite direction, so that pulse b occurs first, a pulse will similarly be produced at output 6. The circuit may comprise rectifier gates and transistor amplifiers (Fig. 2, not shown) or resistor/ rectifier gates and tetrode amplifiers (Fig. 3, not shown).

Classes 78 (iii) and 78 (iv). In a fork lift truck of the kind adapted to handle stacks of bricks, the lowest courses of which are placed between the fork tines, resilient blocks are secured to each tine so that on initial loading of said tine the blocks deform and grip the bricks. As shown in Fig. 2 (Prov.), the rubber block 25 is surrounded by a sleeve 24 which may be made of canvas or rubber and is secured to the tine 20 and guides 22. These guides engage slots 21 in the tine and have stops 23 which limit the amount of deformation of the block. In a modification (not shown) the block is dispensed with and the air in sleeve 24 constitutes the resilient member. In further modifications (also not shown), the sleeve 24 is bonded to a pair of dovetail section bars which respectively engage complementary slots in the tine and an upper bar which contacts the load, and the guides 21 can be dispensed with. The block and sleeve can have a circular, rectangular or substantially elliptical cross section. A modification of this arrangement, shown in Fig. 5 (Prov.), has a pair of block containing sleeves 31, 32 dovetailed to an upper bar 30 and a tine 20, a single guide member 22 being provided.
