Title: Seaming process

Filed: 1974-04-16
Abstract: 1441067 Seaming non-metallic sheet material IMPERIAL CHEMICAL INDUSTRIES Ltd 21 March 1975 [16 April 1974] 16446/74 Heading B5K Two thermoplastic polymeric sheets are seamed together by causing the sheets to converge and directing towards the line of convergence at least one focused beam of energy from a laser. The sheets may be films or knitted woven or non-woven fabrics containing thermoplastic continuous filaments or staple fibres, e.g. crimped polyester fibres. During seaming, the sheets may be held stationary relative to each other and to the laser beam or there may be a stepwise or continuous relative movement between the laser beam and the sheets. If the laser beam is movable, its position relative to the sheets may be controlled by a programmer e.g. a punched tape or a magnetic tape. The sheets may be brought together by passing them bwtween two plates, around two bars or between two moving belts. The laser beam, which is preferably pulsed or chopped, may be oscillated over a narrow width to produce a seam comprising two or more rows of weld points. After seaming, the fabric may pass into a laser cutting device controlled by the same programmer which controls the seaming laser. As shown, apparatus for seaming together two fabrics to produce garments comprises fabric supply rolls 1, 2 and driven nip rolls 3, 4 to bring the fabrics together. Two pulsed laser beams 5, 6 are traversed along the nip 7 be tween the rolls 3, 4, the speed of the rolls 3, 4 and the positions of the beams 5, 7 being controlled by a computer. The seams form shoulder seams 10 and side seams 9 of a dress which is subsequently cut-out.

Title: Data handling systems
IPC: H03M13/00
Filed: 1974-04-18
Abstract: 1432535 Error detection and correction INTERNATIONAL BUSINESS MACHINES CORP 18 April 1974 [29 May 1973] 16971/74 Heading G4A An encoder/decoder comprises a plurality of  identical modules 0-7, Fig. 6, each receiving a respective byte B0-B7 of an input code word and generating a respective check bit C0-C7 which is a function of a corresponding code group of information bits selected from the code word. Fig. 4 shows one partition of the parity check matrix on which the encoder/ decoder is based, the partitions all being identical except that they are cyclically shifted relative to each other, i.e. row 1 in the partition shown becomes row 2 in the next partition for bits 8-15, C2 and so on. The basic partition may also be chosen so that each information bit is assigned to the minimum number of code groups (rows) and so that the partition contains the maximum number of all zero rows, so that the number of input/output pins per module and the inherent circuit delays can be minimized. The basic module is shown in Fig. 5 and comprises first logic (mod 2 gates 20-24) for generating first parity signals P(i), W(i) for each of the partial code groups (rows) to which the information bits B of the byte input to that module contribute. These first parity signals are combined by further logic (mod 2 gates 40, 41) in the various modules to produce the check bits C0-C7, the connections between the modules being as shown in Figs. 5 and 6 to effect the cyclic permutation of the partitions of the parity check matrix. As an example, outputs W 2  (3) to W 2  (7) of module 2 are connected to input terminal 35, 34, 33, 32, 31 respectively of modules 3, 4, 5, 6, 7 and inputs on terminals 31-35 are received from modules 5-7, 0, 1. Each module produces the parity bit P for its respective byte and is unsable in a memory store cycle to generate the respective check bit C0-C7 and in a memory fetch cycle to combine the stored check bits with the parity signals generated from the stored information bits to generate a syndrome bit S0-S7. The syndrome bits are used in a conventional manner to indicate the presence of a single or double error and to locate single errors for correction, e.g. by inversion in exclusive OR gates.

Abstract: 152,728. Parsons, Sir C. A., Bennett, E., and Rowe, H. July 9, 1919. Arc lamps.-In a search-light or other projector, non-radiant heat is abstracted so as to minimize heating of the mirror and allow of the use of large currents. For this purpose the arc may be surrounded wholly or partly by a water-jacket, which also cuts off radiant heat from the projector barrel. As shown in Fig. 1, the jacket a surrounds the arc except for a gap allowing passage of the positive carbon-holder. A chimney g may pass through the jacket, and escape of the fumes may be aided by suction or by forcing air into the barrel. Pipes e, f leading from the jacket terminate at different levels in a tank c. One pipe may open into a sump at the lower part of the jacket. If the jacket completely surrounds the are, its lower part is of V or other shape preventing the collection of steam. The aperture of the jacket may be of funnel shape.

Abstract: 1387941 Making superconducting coils UNION CARBIDE CORP 14 April 1972 [16 April 1971] 17212/72 Heading B3A [Also in Division H1] A method of fabricating a superconducting coil 30, Fig. 3, from a flat strip of electrically conductive tape 10 comprises cleaning one side of the tape to provide a substantially oxide-free surface, roughening the surface to a roughness of at least 125 micro-inches root mean square, passing the roughened side of the tape at a predetermined speed beneath a high velocity, high thermal content arc plasma 18, Fig. 1, of metallic particles to form a superconductive coating in direct contact with the roughened surface, cooling the underside of the tape as the tape is passed through the arc plasma, laying electrical insulation upon the coating to form a multi-layer composite structure, and winding the structure about a mandrel to form the desired coil configuration. The tape supplied from a reel 12 may be of copper, aluminium or silver or a composite of copper backed with stainless steel, and is roughened'by an abrasive wheel 16, although other techniques may be used, before coating with metallic particles using an arc torch 20. Superconducting materils used in the torch are mixed Nb, Sn powders; V, Si powders; Nb, Al powders; prealloyed V 3 Ga, Nb 3 Sn, NbTi, V 3 Si, or Nb 3 Al. The tape may be cooled using a water-cooled wheel 22 or a jet of carbon dioxide. The tape is then passed over a dispenser wheel 24 which applies a thin coating of a fast drying liquid ceramic as an insulator for electrically isolating each turn of the tape, except ends of the tape which may be joined, as it is wound on to a take-up reel 14. Alternatively, an insulating layer may be superimposed upon the superconducting coating from a separate spool (not shown). Insulating materials that can be used include silica or high temperature glass cloth tape, liquid ceramic suspensions and high temperature enamels. A solenoid may be formed from a plurality of such coils 30 by welding together inner and outer ends of adjacent coils at joints 32 using TIG welding and then coating the weld with superconducting layers by passing under torch 20. The solenoid assembly can then be heat treated in a furnace to increase the superconducting properties of the coating. Alternatively, the coils may be heat treated separately before being joined. The coils are highly stabilized, i.e. capable of carrying superconducting currents up to the critical current level of a test sample without degradation, and are substantially unaffected by rate of coil charging.
