Filed: 1964-08-31
Abstract: <PICT:1107142/C1/1> In apparatus for use in the production of flat glass by the "float" technique, the outlet end wall 3 of the "float" tank is a refractory wall faced on the outside with a metal plate 15 which forms one wall of a cooling box 16 having an inlet provided with means for supplying a cooling medium under pressure to the box 16, an outlet for discharging the medium from the box and baffles in the box to constrain the cooling medium to flow against the metal plate 15 through a tortuous path in the box between the inlet and the outlet.  Preferably, the box 16 is divided into two parts by a central vertical partition 19.  Each half has an inlet 22, 23 for the cooling medium near the partition, an outlet at the bottom of the box near its outer end and baffles 24, 25 defining the tortuous path between inlet and outlet.  The cooling medium is preferably a reducing atmosphere (e.g. an inert gas containing 5% of hydrogen) which is discharged from the box 16 directly into a chamber enclosing a roller 6 arranged to take up the ribbon of glass from the "float" tank, a plenum of protective atmosphere being maintained in this chamber and being augmented by the discharged atmosphere.  The metal plate 15 is made of heat resistant stainless steel and is maintained at a temperature 200 DEG  C. below that of the molten metal in the "float" tank. The cooling medium is supplied at a rate of 500 c.f.h.

Title: Improvements in indexing mechanism for machine tools
IPC: B23Q16/02
Filed: 1958-11-10
Abstract: 861,771. Broaching; machine-tool details. CINCINNATI MILLING MACHINE CO. Nov. 10, 1958 [Nov. 13, 1957], No. 35979/58. Class 83 (3). Indexing mechanism for a rotary member in a machine tool comprises a worm-wheel secured to the member, a drive-shaft having a driveworm mounted thereon and engaged with the worm-wheel to rotate the member, a second worm engaging the worm-wheel and rotatable with the drive-worm, locking mechanism to terminate rotation of the drive-shaft after a predetermined rotation, and actuating mechanism to shift the second worm longitudinally after rotation of the drive shaft is terminated. The indexing part 36, Fig. 3, of the table is supported on a vertical stub-piece 25 by an anti-friction bearing 28. A worm-wheel 82 is secured to the indexing-part and is engaged by two worms 74, 87, Fig. 2, arranged at right angles in the stationary part 16 of the table, and adapted to rotate in unison by connecting bevel gears. A fluid motor 107 drives the worm-shafts and also a train of gears 81, 110, 111 to rotate a control shaft 112. The shaft 86 of the second worm is in two parts, that part carrying the worm telescoping into the driven part with a splined connection. This enables a fluid-operated wedge 183 to move the worm 87 axially to take up backlash between the two worms and the table when the table reaches an indexed position determined by a latch 230, Fig. 7, and a stepped cam 115 on the control shaft 112. A further cam 116 on the same control shaft operates a valve to slow down the motor prior to the latch 230 engaging. Three sets of clamping levers 59, Fig. 3, are arranged in the base for the table. These are moved, to clamp a rim 39 secured to the table, by buttons 60 moved upwardly by fluid-pressure pistons and wedges. Broaching.-The indexing-table carries a workpiece 19, Fig. 3, clamped by a spider 51 and nut 53, and is described as applied to a broaching-machine 15, Fig. 1. The table is carried on a slide 14 moving at right angles to the broach 20, which moves on a slide 17 from left to right for the cutting operation. All the operations are automatic once the machine has been started, and the controls comprise electrically operated fluid-pressure valves. The table may be indexed rapidly through a number of positions when setting up, and the indexing angle may be varied by changing the ratio of the gear train 81, 111, Fig. 2.

Title: Apparatus for decoding graphic-display information
Inventor: PITTEWAY MICHAEL LLOYD VICTOR
IPC: G09G1/10
Filed: 1968-07-29
Abstract: 1,244,659. Cathode-ray tube displays. NATIONAL RESEARCH DEVELOPMENT CORP. 17 July, 1969 [29 July, 1968], No. 36172/68. Heading H4T. In an arrangement for displaying curves (including straight lines) by orthogonal deflections of the beam of a cathode-ray tube (or the pen of an incremental plotter) the curves being specified by first and second items of information specifying respectively, in which of a plurality of sectors the curve or portion thereof is to be displayed and in which of a plurality of directions elemental straight lines making up the curve are to lie, decoding apparatus is provided comprising sector-selection means which in response to the first item of information provides output signals specifying elemental lines in the selected sector, the directions of such lines being as specified by the second item. Thus by employing a plurality of sectors (Fig. 3) in each of which the direction of the elemental lines may be parallel to either of the defining bounding lines, the accuracy with which curves are produced is increased in comparison with systems utilizing only two directions, e.g. parallel to the horizontal or at 45 degrees thereto (Fig. 2 not shown). In the operation of the present invention the complete code for one curve (which may be a portion of a larger curve) comprises: an initial bit-"beam-on"; ten bits specifying the X co-ordinate and ten bits specifying the Y coordinate of the start position of the curve; eight bits, N, specifying the number of elemental lines which make up the curve; three bits W, X, Y, specifying the sector (in this ease, octant); a number of bits m specifying the direction of each of the elemental lines and one bit c specifying whether or not the next curve starts, at the end of the curve just specified. Information coded in this manner for all the curves is deposited in a file 10 (Fig. 1) and when a display is required such information is sent, e.g. by a telephone line, to a recycling buffer-store 11 which may be a delay line from which it is supplied to the decoding apparatus (logic Hardware) 12. The flow chart of Fig. 5 indicates the requirements for the logic hardware (Fig. 6, not shown) which operates by testing (30, 31, 32) the first m bit against the w, x and y bits to provide the required change in the X, Y co-ordinates necessary to trace the first elemental line in the required direction. The number N is then decreased by 1, (37) and if the remainder is zero the beam is switched off. If not zero, the next m bit is tested against the w, x and y bits and this cycle continues until N becomes equal to zero. After each cycle the c bit is tested and if this is "1" the next curve continues from the co-ordinate portion of the end of the previous curve. If not zero the system waits for the next beam "ON" bit. Fig. 4 shows a curved character "S" produced by the system.

The discharge device 8 extinguishes itself after a predetermined interval and restores the circuits to their condition of rest. A variable impedance 10 is connected in series with the tube 8. The controlled apparatus 9 may be a relay which operates when the voltage drop across it has fallen to a predetermined value, and before the extinction of the arc occurs ; and a plurality of relays having different drop-out voltages may be operated in succession in this way. The tube 8 may have one or more control electrodes, which may be connected with the switch 3 ; the latter may then be of small current-carrying capacity. The invention may be applied to circuit-breakers for preventing overloading of circuits.

Title: Manufacture of artificial fibres from viscose
IPC: D01F2/08
Filed: 1929-11-29
Abstract: Viscose silk of high tensile strength, for example, 3,5-5 grams per denier, is obtained with the use of a coagulation bath containing 30-55 per cent sulphuric acid and more than 20 per cent of a bisulphate, for example, ammonium or sodium bisulphate.  The bath may contain other sulphates and bisulphates, such as zinc, magnesium and aluminium sulphates, and also the usual additions such as glucose, glycerine, and aniline sulphate.  It is advantageous to apply to the threads additional stretch either in the coagulation bath, or between the coagulation bath and the collecting device, or at both places. The strength of the threads is higher the finer the individual titre; with titres below one denier, additional stretching is necessary. Ripened or unripened viscose may be used, and it is advantageous if the viscose is prepared from unripened alkali-cellulose; further it is an advantage to arrange that the viscose shall be of high viscosity, either by rinsing the cellulose content or by taking precautions to avoid degradation during its manufacture.  The viscose may contain less than 5 per cent of alkali, or quantities larger than this.  Specifications 10094/06, [Class 2, Acids and salts, Organic &c.], 274,521, 281,351 and 317,608, [all in Class 2 (ii), Cellulose &c.], are referred to.
