The thermocouple consists of a plate 5, e.g. of constantan, either soldered at 4 to the duct which may be of the same material, or integral with it, and a copper connector 6 soldered to its remote end 7. The connector is taken through the air-gap and soldered at 8 to the other side of the duct. Instead of being of resistive metal, the duct 1 may be of insulating material, e.g. ceramic, in which case current electrodes 4, 8 are arranged as inserts, e.g. by diffusion through the ceramic. The connector 6 is termally insulated from the plate 5, e.g. by an air space 15 or insulating material. Connectors as 6 may pass above and below the duct, or may be replaced by conductors passing through open or closed slots in one or both pole-faces, or by loops passing on either side of the poles.
Patent GB-1073626-A (GB)
Title: Process for the production of chlorine
IPC: C01B7/04
Filed: 1964-06-23
Abstract: Chlorine is produced by reacting NH4Cl vapour or HCl in countercurrent contact with granular MgO in a zone wherein there is a temperature gradient from a low temperature of at least 350 DEG  C. to a high temperature of at most 600 DEG  C., in the direction of MgO transfer to produce a product comprising MgCl2, and oxidizing said product with an oxygen-containing gas to produce chlorine, the granular MgO thus formed being recycled to the chlorination stage. The chlorination of MgO may be carried out in one or more fluidized beds or in a longitudinal or vertical moving bed, the reaction temperature being controlled by jackets through which suitable cooling, heat-insulating or heating media pass and by the direct introduction of MgO into a high temperature zone.  The first stage of the chlorination of MgO, to MgOHCl, may be effected in a zone at 350 DEG  to 420 DEG  C. and the final stage, in which MgOHCl is converted to MgCl2, at 500 DEG  to 550 DEG  C.  The NH4Cl or HCl employed may be diluted with inert gas, e.g. N2. For instance, a mixture of NH4Cl vapour and inert gas may be obtained by blowing an inert gas into a heated fluidized bed of ammonium chloride crystals and silicate, silica sand or alumina.  The MgCl2 produced in the chlorination stage is oxidized with O2 or air in a fluidized or moving bed.

Title: Numerical control system for multiple slide machine tool
IPC: G05B19/19
Filed: 1971-04-19
Abstract: 1307470 Numerical control of machine tools BENDIX CORP 19 April 1971 [13 April 1970] 26150/71 Heading G3N In a numerical control system for simultaneously controlling the motion of a plurality of independently movable members of a machine tool from a single information source, e.g. for a vertical turret lathe, Fig.1, having independently movable heads 16, 18 supporting respective cutters to act on a single workpiece 14, the cutter being programmed on a single punched tape. Commands for the two heads are arranged in blocks, each block being prefixed by a code designating to which head the following information is addressed, so that the control operates to ensure that the cutters will not attempt to occupy the same space at the same time. Means are provided to inhibit the reading of such following command information until all previous commands to heads have been completed. Two cutters can be addressed by the same codes, e.g. a single code can be used to indentify the feedrate command to first and second cutters and the cutter it is addressed to is determined by the identification code which prefixes the block in which the command is contained. Codings for both cutterheads 16, 18 on a tape 30, are read by a reader 32. A decoder 34 determines the address of the coded information and routes it either to an X-Y controller 36 which provides signals to a pair of servomotor units 40, 42 which respectively effect horizontal (X) and vertical (Y) motions of head 16, or to a U-W controller 38. The controller likewise controls servomotor units 44, 46 which effect horizontal motions of head 18 along complementary axis U and W. Feedback transducers in the servo units send signals to respective controllers 36, 38, indicative of the amount of movement effected by the servomotors. Certain decoded signals are also fed to start/ stop control 39 to halt the tape reader until the control 39 receives signals from the controllers 36, 38 indicating that the X-Y or U-W servos have completed their last command motions. Subsequent command signals are then read, decoded and fed to that controller. Signals representing cutting mode (e.g. linear or circular) and feedrate for each controller are stored by that controller until the next signals of that type are read. (For Figures see next page)

Title: Automatic brake adjusting mechanism
IPC: F16D65/54
Filed: 1962-07-09
Abstract: 993,868. Brake adjusting devices. F. A. E. PORSCHE. July 9, 1962 [July 13, 1961], No. 26193/62. Heading F2E. An automatic adjusting mechanism for calliper-type disc brakes comprises a friction ring 24 slidably mounted on a guide bolt 18 secured to a brake-operating cylinder wall 28 of the brake calliper housing 7, 8 and contacting frictionally the walls of an inner bore 17 of the brake applying piston 14 acting on friction members 9, 10 of the brake, in which the return path of the friction ring 24 is larger than the brake clearance to permit displacement of the disc 3 when cornering the vehicle, the return path of the piston being opposed by the action of an equalization spring member 27. A supporting ring 26 is retained between a collar 25 on the guide bolt 18 and an abutment member 29, the clearance s denoting the normal brake lining clearance and the distance a denoting the clearance provided to allow for disc displacement when the vehicle is being cornered. If the deviation of the position of the brake disc 3 is larger than the play s, then the friction ring 24 abuts against the supporting ring 26 against the force of the equalization spring 27 in the direction of the abutment thereof. The distance a between the supporting ring 26 and the abutment member 29, which is decreased during this operation, is so dimensioned that it corresponds to the maximum possible brake disc variation or deviation. The opposite acting piston arranged within the brake calliper half 7 remains unaffected by this displacement operation and remains stationary. After the vehicle has been driven through the curve and moves along approximately straight road section, the brake disc 3 returns to the normal position. Fig. 2 shows the brake released condition when the brake disc distorts to the full line position shown and where the linings are badly worn.
