Patent GB-862270-A (GB)
Title: Improvements in or relating to data-storage and data-processing devices
Inventor: BEZDEL WINCENTY
IPC: H04Q3/00
Filed: 1957-11-08
Abstract: 862,270. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 8, 1957, No. 34885/57. Class 40 (4). Means for allocating time-positions in a time-division multiplex transmission system to a calling line comprises a co-ordinate array of cells in which each row is allocated to a timeposition. While a time-position is not in use the associated row is arranged to store a number which is cyclically varied according to the numbers of the lines, variation of the number ceasing when a calling line is encountered. The co-ordinate array makes up a store and may be arranged as a coordinate arrangement of toroids, a perforated ferrite plate, or a number of columns of delay lines or stepping pattern registers. The store has a row of storage cells for each time-position in a 100-division multiplex system. Each row has two groups of digit cells 1-5 and 6-10 and a group of three control cells. The rows are read one by one in a recurring cycle under the control of a pulse generator and distributer. Assume a number 9 has been read from a row and there is no entry in the control cells (read cycle 1, Fig. 10). This number energizes the appropriate column circuits in the group 1-10, Fig. 1. Unity is added by the control gates so that the number 10 is recorded in the digit cells together with an entry a in the control cells. When the row is scanned for the second time the numbers 10 and a are read. The entry a enables the access gates so that the digits 1 and 0 operate a cell in a co-ordinately-arranged access selector whereby a pulse is delivered to a test gate GT10, of the type described in Specification 824,222 associated with the line 10. If the line is idle no pulse P is delivered and the number 10 is rerecorded with no entry in the control cells. When the row is scanned for the third time the number 11 is entered together with entry a in the control cells. The process continues with the time-position represented by the row being effered to all lines in turn during alternate cycles. If, however, the line 10 is engaged when tested in the second cycle the associated test gate GT10 delivers a pulse P which operates the control gates of Fig. 1 so that the same number 10 is re-recorded with a different entry b in the control cells. These entries are re-recorded at each scan until a comparator is available and receives the digit 10. The entry b is then replaced by c. During one complete cycle the number 10 is compared with the numbers read out from the other rows whose time-positions have been allocated. If identity is found the comparator (Figs. 7 and 8, not shown) is released and the time-position is offered to other lines. If the cycle is completed without identity being found the comparator is released and entry c is replaced by d. The entries 10 and d are then read and re-recorded for the duration of the call on the line 10. Specification 862,271 also is referred to.

Filed: 1920-12-14
Abstract: 181,038. Debay, G. C. Dec. 14, 1920. Endless chain machines.-A machine for making cored blocks from plastic material comprises an endless conveyer or chain 10 mounted on sprocket-wheels 11, 12 and having secured thereto mould-members 13. These comprise a bottom 14 and a side member which is formed in three sections 15, 16 17 having registering openings 22, the sections 16, 17 being hinged at 18 to the section 15. Core-bars 23 are pivotally secured at one end to pedestals 26, and are supported at their other ends in the openings 22 in the moulds; the bars have a varying crosssection, as shown in Fig. 6, the full-sized portions 23b fitting closely the openings 22. Plastic material is fed to the moulds, as these are carried along by the conveyer, from a trough 28, the material being delivered by a spiral 28a to a vertical receptacle 29, and from the receptacle, which is divided vertically by a partition 33, by two spirals 34. A roller 41 is provided to bear upon the material as it passes from the receptacle 29, and end walls 30 form, with the mouldmembers, the complete moulds. The material is fed into the moulds at a point of the core-bars where these have a small cross-section. As the moulds move, the increasing cross-section of the bar compresses the material outwardly into the mould and also forms openings of the desired size in the blocks. As the mould-members turn down, after removal of the blocks, into the lower run of the conveyer the sections 16, 17 fall to the position shown in Figs. 1 and 3 to enable the core-bars to enter the mould-members. The sections 16, 17 are closed down by engagement with guides 45. In a modification, the sprocketwheels have flat faces, and the lower rear edge of each mould-member is hinged to the forward edge of the following member, so that as the members pass around the wheels, the bottom pieces of the members engage with the flat faces.

Title: Method for the manufacture of Flexible Sheet Material
Inventor: COWX CYRIL
IPC: D04H5/04
Filed: 1965-08-20
Abstract: 1,192,351. Laminates. DUNLOP CO. Ltd. 9 Aug., 1966 [20 Aug., 1965], No. 35778/65. Addition to 989,433. Heading B5N. [Also in Division D1] A leather-like sheet material is manufactured by forming a mat of crimped continuous filaments, consolidating the mat in the presence of material affording a bonding agent, and pressing the mat of crimped continuous filaments into contact with an openwork net fabric during or subsequent to consolidation of the mat, the crimped continuous filaments having been subjected to tension and allowed to relax before the mat was consolidated. The mat of crimped continuous filaments may be formed by (a) plying together at least two separate layers of crimped continuous filaments which have been collected under tension; (b) collecting under tension, preferably substantially parallel, crimped continuous filaments to the desired depth which upon relaxation provide a mat of crimped filaments; or (c) drawing off a creel or beam an assembly of tensioned crimped continuous filaments to the desired depth, which are then relaxed to form a mat. The crimped continuous filaments may take the form of a stretch yarn treated by a torque twisting process, an edge crimped twistless yarn, or a chemically crimped yarn. Specified filaments are those made of nylon, polyethylene terephthalate, polyacrylonitrile, polyolefines, rayon and natural silk. The bonding agent may be a thermoplastic resinous or elastomeric binder preferably flexible at room temperature. It may be of a composite nature, i.e. there may be a first bonding composition which bonds the fibres simply at their crossing points and a second composition which extends more generally around the filaments. Specified elastomeric binders are polyurethane rubber, natural rubber, butyl rubber, rubbery styrene-butadiene copolymers, butadieneacrylonitrile copolymers and polychloroprene rubber. Polyolefines, e.g. polyethylene, are specified as suitable resinous binders. The binder(s) may contain curing agents and plasticizers. The consolidated mat may have a layer of polypropylene staple fibres needled to one or both faces thereof as described in Specification 1,042,028. Another form of consolidated mat may be as described in Specification 1,105,484. Preferably, the bonding agent is at least partially cured prior to pressing the mat into contact with the open-work net fabric. This fabric may be of metal, e.g. steel, or a synthetic plastic material, e.g. polyethylene, and may have a diamond or rectangular, e.g. square, mesh structure. The pressing of the mat with the net fabric can be carried out at room temperature or at an elevated temperature. It may be carried out in a press, the plates of which may, if desired, be heated and the time of contact is from 5-20 seconds, preferably 10 seconds. Only one or both faces of the mat may be pressed with the net fabric. A face of the mat may be buffed prior to pressing with the net fabric and after the mat has been pressed with the net fabric and consolidated it may be dyed.
