Abstract: 1359482 Grooving sheet material R E ING- HAM & CO Ltd 19 April 1971 [6 March 1970] 10797/70 Heading B5L A machine for cutting Vee grooves in sheet material 4 comprises one or more cutting heads each of which is adapted to cut one or more grooves in a single pass of the material 4 through the machine. Each cutting head comprises a rotary cutter 1A, 1B or 1C an anvil means 2A, 2B or 2C which is fixed in co-operative relationship with the cutter so that material being cut is supported on the anvil means and the clearance between the cutter and the anvil means dictates the thickness of the membrane joining the sections of material on opposite sides of each groove, and a pressure means 3 which is vertically adjustable and resiliently presses the material into contact with the anvil during cutting. In one machine described, each cutter head is adjustably mounted on a pair of beams 19 extending transversely of the material feed direction and the cutter heads are spaced along the direction of feed. The material may be fed by pairs of rollers which may be angled so as to keep one edge of the material against a fence 14 whilst its other edge is trimmed by a circular saw 15. Alternatively the material is fed by a chain or endless belt against which it is held by a further resiliently urged endless belt. In this case the edges of the material may be bevelled by a rotary cutter or circular saw. The sheet material may be hardboard or chipboard which may be laminated with a vinyl sheet.

Abstract: 1,163,816. Aromatic polycarbonates, polyesters and poly(sulphone-ethers). GENERAL ELECTRIC CO. 8 March, 1967 [9 March, 1966], No. 10914/67. Heading C3R. In the manufacture of aromatic polycarbonates, polyesters and poly(sulphone-ethers) from dihydric phenols, products which are fireproof and of controlled molecular weight are obtained by effecting the reaction in the presence of a monohydric phenol having 2, 3, 4 or 5 halogen substituents or a salt of such a phenol and an alkali metal, an alkaline earth metal or magnesium. The polycarbonates are derived by reacting a dihydric phenol with a carbonyl halide or a bishalo-formate and in the examples are derived from bisphenol A and phosgene. The polyesters are derived by reacting a dihydric phenol with an acid halide of a dicarboxylic acid (e.g. isophthalic or terephthalic acid). The poly(sulphone-ethers) are derived by reacting a dialkali metal salt of a dihydric phenol and a dihalogenated diaryl sulphone.

Title: Pcm tdm telecommunications systems
IPC: H04Q11/04
Filed: 1974-03-13
Abstract: 1465076 Automatic exchange systems SIEMENS AG 13 March 1974 [30 March 1973] 11089/74 Heading H4K In a time-space-time, 4-wire switching system through which supervisory and synchronization data are switched during respective dedicated time slots in each frame, the crosspoint control words for the data switching are obtained directly from the exchange clock pulse train and not from a switching control store which is used for controlling switching of the PCM speech channels. As shown each 32-channel incoming highway Ak is terminated in an 8 bit serial register SP1 whose contents are parallel buffered in store SP2 before entry into a specific memory location of store KVS under control of a time slot counter LZ which is tied to the prevailing slot rate on the highway. The exchange clock AT steps a 64 place phase counter PAZ1 which addresses a time switching control store VHS. The latter contains the addresses of those compartments of KVS which must be read out during successive time slots into buffer store SP3. A space switching control store KHS is similarly addressed by PAZ so as to route the words in SP3 in serial format through a space switching network D and M to an input buffer SP4 on the outgoing side of the network. The words are then written into store GVS at the relevant location under control of the time control store VHS. Finally words are read out to the outgoing highway Ag at the exchange time slot rate under control of a 32 place phase counter PAZ. In contradistinction to the information (speech) words, data words in the 1st and 16th time slots of each frame are read-out from KVS, written into GVS and switched through to/from the relevant data processing equipment via D/M under direct control of the phase signals from counter PAZ1. The advantage of this is alleged to arise when the switching network is expanded since it is not then necessary to make any extra provision for extracting/inserting data into the bit streams.

Title: Apparatus for the closed circuit dry spinning of artificial or synthetic fibres
IPC: D01D5/04
Filed: 1958-04-09
Abstract: <PICT:0825344/IV (a)/1> A dry-spinning apparatus of the "closed circuit" type comprises a substantially vertical outer shell having a lateral opening at a level well spaced from both ends of the passage of a yarn and a drain at its lower end, a downwardly facing spinneret in the shell adjacent to its upper end, a tube within and substantially coaxial with the shell, its upper and lower ends being spaced from the upper and lower ends of the shell respectively and the tube being provided with an aperture at least sufficient for the free passage of a yarn opposite the lateral opening in the shell, means for heating a gas passing down the tube above the aperture, means for cooling a gas passing down the tube below the aperture, and yarn guide means so positioned that filaments formed in the apparatus may be drawn round it and out from the tube and shell through the said aperture and lateral opening after they have passed through the upper part of the tube.  The heating and cooling means may comprise jackets for the passage of heating and cooling fluids, and the heating means may also heat the annular space between the upper portion of the tube and the shell.  The aperture in the tube and the lateral opening in the shell may be approximately equidistant from the two ends of the shell.  As shown, a shell 1 terminates in a cone 2 and drain 3, and has mounted at its upper end a spinneret mounting 4 and spinneret 5.  Opposite the lateral opening 7 and tube aperture 6A is a yarn guide pin 6.  A tube having upper and lower portions 8, 9 is provided with heating and cooling jackets 10, 11 respectively. In operation, the drag of the filaments 12 draws air down through the heated upper tube portion 8, and the air takes up solvent vapour from the filaments. The filaments are drawn aside at guide pin 6, but the solvent-laden air continues under its own momentum to the cooled lower tube portion 9, where it is cooled and at least part of the solvent vapour condenses.  Condensate leaves via drain 3, and the air flows from the lower end of 9 into the annular space between the tube and the shell, is heated in the upper part of the annular space by jacket 10 and returns to the vicinity of the spinneret. Specification 605,612 and French Specification 658,700 are referred to.
