Title: Arrangement for the evaluation of telegraphic signals of a binary code
IPC: H04L17/30
Filed: 1958-10-24
Abstract: 855,363. Type-printing telegraphy. VIERLING, O. Oct. 24, 1958 [Oct. 24, 1957], No. 34057/58. Class 40(3). In a teleprinter receiving circuit for response to equal length code combinations of signal elements comprising a control device having a number of bistable stages switchable in succession so that at any time one stage is in a condition different from that of all the other stages, in combination with electronic switches comprising elements connected together in series to form a chain circuit, and with the number of elements in successive stages progressively doubled to form a selective path to a recording member, the control device is a ring counter of which the successive stages control an equal number of storage devices serving to control the several elements of the successive stages of the chain circuit and these storage devices can be operated by the incoming signal elements solely when the associated stage of the ring counter is in a switched condition different from that of all the other stages of the ring counter. The incoming signal S is applied to a circuit 1 which reverses the polarity of the negative pulses to form a train of unidirectional pulses S<SP>1</SP> stepping a ring counter R having successive stages 2, 3, 4 which prime bistable storage circuits 5, 6, 7 to which incoming signal S is applied. The initial pulse, positive or negative, produces a corresponding pulse from the circuit 5 when primed by the stage 2, and the positive or negative pulse is passed by diode 9 or 10 respectively. The second pulse is passed from circuit 6 to two pairs of diodes 11, 12 and 13, 14 and a path is selectively built up to one of the four diode pairs 15, 16-21, 22 to which the positive or negative pulse from the circuit 7 is passed via resistors 7a-7d to select one of the diodes of the selected pair and to prepare a circuit to one of the terminals 24-31 leading to a printer magnet. The circuit is completed via conductor 33 to an oscillator Q to produce an operating pulse by a circuit 32 operated after a slight delay by the operation of the stage 4 of the ring counter R. The operation of the actuated element is arranged to provide a pulse to restore the counter stages 2, 3, 4 and the bistable circuits 5, 6, 7 to their normal conditions. If the receiving arrangement is combined with a keyboard transmitter the ring counter R may be utilized to transmit pulses to line in accordance with inputs to the circuits 5, 6 ,7 selectively determined by the operation of a key of the keyboard. The system shown may be extended to deal with a 7-unit code in which the seventh impulse is used as a check signal indicating an odd or even number of marks in the 6-unit signal code combination.

Abstract: 1396251 Coiled web; apparatus for coiling a web WINDMOLLER & HOLSCHER 18 July 1973 [29 Aug 1972] 34209/73 Heading B8C In a coiled web 1 of flattened paper, or plastics, bags or sacks connected end-to-end along transverse lines 4 of weakness provided in the web a relatively weak adhesive 9 is applied, on the side of the web facing the interior of the coil to the trailing end, as viewed in the direction of coiling, of at least the outermost bag, or sack, in the coil. As shown in Figs. 1 and 2, each bag is formed by a weld seam 5 which is located respectively in advance of, or trailing, the corresponding transverse line of weakness 4, in the unwinding direction of the roll 1, so that, when a bag is torn off the end of the roll, the adhesive dabs 9 are disposed respectively adjacent the mouth, or base of the bag. Each bag may have side folds, or gussets; and the adhesive is preferably pressuresensitive. Wider bags, e.g. waste disposal bags, can be folded about one, or more, longitudinal fold lines so as not to cover the adhesive dabs 9, the preferred method being shown in Fig. 3, whereby marginal portions 10, 11 are folded inwards to define a gap S between them and to expose, and slightly overlap, the adhesive 15. In an apparatus for forming a roll of web shown in Fig. 3, a flattened tubular web is unwound by feed rolls 25, 26 from a reel 21 and passes successively through perforating rolls 23, 23<SP>1</SP> and a welding station 28 which includes a plurality of welding jaws 29, 29<SP>1</SP> which are mounted to co-operate on the adjacent vertical runs of a pair of conveyer arrangements, not shown, the speed of the outer return runs of which can be adjusted according to the speed of the web and the desired interval between adjacent weld seams. An adhesive roller 39 and tray 38 is located next to the welding station to transfer adhesive to pads 37 carried by the jaws 29. The web is pulled from the welding station 28 by the rolls 33, 34 of a feeding device 32 which has a fine speed control drive 35 to adjust the tension of the web, and which protects the web from tension applied further downstream by the feeding rolls 57 of a web-coiling machine 14. On leaving the feeding station 32 the web is passed over a trapezium-shaped oblique plate 42 on which the web marginal portions are folded downwardly as shown in Fig. 3. The web then passes over guide rolls 51, 52 leading to one, or other, of two alternately operable mandrels 61, 62, a web tensioning roll 59, being loaded by a weight 58. Each mandrel 61, 62 comprises a cluster of rods which can be projected through the front of the machine, and withdrawn again.
