Title: Improvements in and relating to radio repeaters
IPC: H04B7/155
Filed: 1950-03-06
Abstract: 679,154. Radio signalling valve gating circuits. BRITISH COMMUNICATIONS CORPORATION, Ltd., and HEFTMAN, T. S. June 6, 1951 [March 6, 1950], No. 5632/50. Classes 40 (v) and 40 (vi). In a radio repeater system, the receiver 11, Fig. 1, and transmitter 12 of the repeater station are tuned to the same frequency and are rendered inoperative alternately, a device 16 being adapted to store signals received while the receiver is operative and to apply the stored signal to the transmitter during its operative interval. A frequency-changer 13 supplied by the receiver 11 and a local oscillator 14 feeds I.F. signals of a few hundred kc/s. into a delay line 16, the output of the line being fed into a second frequency changer 17 supplied from the local oscillator 14 so as to restore the frequency of the transmitter to that of the receiver. The output of the line 16 also feeds a switch device 18 which when signals exceed a predetermined amplitude appear in the line, switches off the receiver and switches on the transmitter so as to relay the signals in the line until the output ceases and the receiver and transmitter are again switched on and off respectively. The switch-devices 18, Fig. 2, comprise a pair of diodes 19, 20 reversely connected to the delay line 16. The diode 19 is biased by a battery 23 to render the receiver pentode 24 normally conducting but to prevent charging of the condenser 21 in response to noise. The diode 20 is rendered normally non-conducting by a battery 27 and the transmitter valve 28 which is connected to the frequency changer 17 through a resistor 29 is made normally non-conducting by a biasing battery 30. When signals in the delay line 16 exceed the bias on the diodes, the condensers 21, 25 are charged, the former rendering the valve 24 non-conducting and the latter opposing the bias provided by source 30 to render the valve 28 conducting. The delay-device may take the form of a column of mercury, the received signals being applied at one end through a piezo-electric crystal and picked up at the other end by a further crystal. The switching device 18 also may be in the form of a switch driven continuously.

Title: Wet-type separator for gas purification systems
Inventor: REITHER K
IPC: B01D47/06
Filed: 1972-02-08
Abstract: 1386861 Scrubbing gases KUNSTSTOFFTECHNIK GmbH & CO VERTRIEBS K G 8 Feb 1972 [10 Feb 1971] 5819/72 Heading B1R Gas-cleaning apparatus comprises a cylindrical casing having a gas inlet at or near one end, a plurality of axially-spaced nozzle banks in the casing to spray the gas with a liquid from an external supply, one of the nozzle banks being located near the inlet and pointing in the same direction as the gas flow, and the subsequent bank or banks located downstream of the first and directed countercurrent to the gas flow, a drain for discharge of the scrubbing liquid from the casing, a gas outlet at the other end of the casing, and two axially-spaced transverse partition walls of gas-permeable packing material, one being arranged between the first two nozzle banks, and the other downstream of the second nozzle bank.  In Figs. 1-4 and 6 the apparatus is constructed for horizontal gas passage, and in Fig. 5 for vertical passage. Fig. 1 shows wettype separator 1, reducer 2, droplet separator 3, connecting pipe 4, radial fan 5 with outlet pipe 6, scrubbing agent container 9 with circulation pump 10 and supply pipe 11. The internal structure of 1 is shown in Figs. 2-4. Casing 42, Fig. 2, has flanged inlet 20 and flanged outlet 33 to which the flanged inlet 34 of reducer 2 is bolted, and is divided into three compartments by gas-permeable partitions 24, 25. The compartments each contain one of nozzle banks 21, 22, 23, the first being directed to spray in the direction of gas flow, and the latter two in countercurrent. At the surface of each partition 24, 25 the scrubbing agent is separated from the gas flow and runs down into sump 15 via openings 35, 36 or 37, 38 respectively in the casing wall. Pipe 41 drains sump 15 into container 9 via connection 15, and extends upwardly in 15 to a level above the lower edges of downwardly directed walls 39, 40, which thereby prevent the gas flow bypassing 24, 25. Each nozzle bank is formed with a delivery spider having longer pipes 51 and nozzles 52, and one with shorter pipes 57 and nozzles 58. The Fig. 3 section illustrates spider 51, 52 only, for simplicity. Each nozzle bank. is transversely removable from the casing via tube 43 and may be observed through socket 56. After removal of nozzle banks 21, 22, 23 partition walls 24, 25 are longitudinally removable from the casing, which is provided with stationary retainer ring 26 and loose retainer rings 27, 28, 29 and 32 for this purpose. As in Fig. 1, the purified gas flow from separator 1 enters droplet separator 3 for removal of the remaining entrained scrubbing- agent, and the latter to container 9 via sump 18 and line 19. Sump 15 below separator 1 also returns scrubbing agent to 9. From 9 the scrubbing agent is pumped to the nozzle banks behind closure plates 12, 13, 14. The clean air discharged from 3 through pipe 4 to fan 5 leaves outlet pipe 6 through connection 8. In Fig. 5, the apparatus is slightly modified for vertical gas flow.

Title: Improvements in or relating to means for tensioning rods and the like
Inventor: WOOLCOCK STANLEY RICHARD
IPC: E04G21/12
Filed: 1953-03-03
Abstract: 746,033. Reinforced concrete. UDALLS PRESTRESSED CONCRETE, Ltd. Feb. 24, 1954 [March 3, 1953], No. 5884/53. Class 20(4). In the pre-tensioning of reinforcements for concrete, the rods 13, 14 are tensioned individually by a jack 37 the ram of which is aligned with or is integral with a compression tube 36 having diametrically opposed slots 40 into which project the ends 41 of pivoted claw arms 42 which engage a gripper device 24 on the wire 13 being tensioned. The tension is held by a second gripping device 22 which abuts against a steel plate 17 accommodated in a recess in the end of the beam or like structure 11 being prestressed. A packing plate 18 of metal, hardwood or the like takes up irregularities in the end face of the beam. The plate 18 has a central aperture 20 for the passage of the rods, and the plate 17 is apertured according to the pattern of reinforcement required. The gripper 22 comprises an outer sleeve with a conical bore which receives tapered half members 27 with serrated biting faces. The gripper 22 is moved into contact with the plate 17 when the tension has been applied to the rod, by a key 55 which is insertable through slots 38 in the sleeve 36 and engages a spacer 23. When the jack is to be disengaged, the key is replaced by a wedge which is driven through the slots 38. If, when the jack has been released, it is necessary to increase the tension in the rod, the tension is re-applied to the rod and a U-shaped shim inserted between the sleeve 22 and the plate 17, the end of the tube 36, or an adapter therefor, being made U-shape to permit .this. The gripper 24 is made similarly to the gripper 22, except that the serrated half-members are pressed down the taper by a coil spring. The tension applied to the rod can be read from a pressure gauge 52 and/or a suitably located scale 53. The claws 41 are kept in engagement with the gripper 24 by a slidable band 49, tapers 50 on the arms 42 being provided. Fig. 1 shows the device used for post-tensioning, the passage 12 for the rods being ultimately filled with grout through the duct 58. The rods are cut off beyond the grippers 22 and the spacer 23 and gripper 24 are recovered for re-use. The end of the tube 36 may be fluted to give clearance to adjacent reinforcement rods, and, in certain positions, a curved adapter 70 may separate the tube 36 and the plate 17, the adapter being slotted at 57 to facilitate manipulation of the gripper 22. This permits the device to be used out of alignment with the beam. Fig. 10 shows an arrangement for pre-tensioning, the mould 59 being separated from the gripper 22 by a box-like structure 60. The wires are stressed as before by a jack 37 which is removed when the tension is held by the gripper 22. When the concrete is sufficiently set to hold the tension of the rods, the latter are severed, preferably by an oxy-acetylene flame to minimise the damage to the bond between concrete and rods by a sudden shock of release.

Filed: 1954-03-02
Abstract: 758,039. Weighing-apparatus. NEIKE, R. H. March 1, 1955 [March 2, 1954], No 6108/54. Class 143 Household or other scales comprise two springs of different rating for weighing in "light" and "heavy" ranges, the weighing being automatically transferred to the "heavy" range when the adjustable upper limit of the "light" range is reached. The scale-pan is supported on a stem 15, Fig. 2, fixed to a rectangular frame 16, the latter being mounted on parallel links 17 for movement relative to a casing 11, The lower member 23 of frame 16 is attached to the lower end of a light coil spring 22 having its upper end attached to one end of a bellcrank 19 pivoted to the casing. Depression of the scale-pan against the action of spring 22 causes a rack 24 on frame 16 to turn a pinion 25, thus moving a pointer 13 over the "light" range of markings on a dial 12. The other end of bell-crank 19 coacts with a screw 27, Fig. 3, for adjustment of spring 22 to zeroize the pointer. If the depression of frame 16 is sufficient to cause the pointer to register the upper limit of the "light" range, a forked member 31 on frame-member 23 coacts with a nut 32 on a threaded rod 30 attached to the lower end of a heavy spring 28, the latter having its upper end fixed to the casing through a nut 36 on a threaded rod 29. Further depression of frame 16 due to heavier loads in the scale-pan is against the action of both springs, and the pointer moves over the "heavy" range of markings on the dial. Nuts 32. 36 allow adjustment of the point at which the heavy spring becomes operable, and the latter may be initially tensioned by a weight 34. The springs may be mounted ore above the other. Fig. 4 (not shown), and the springs may be of leaf rather than coil construction. A modified form of scale is described, Fig. 5 (not shown), in which the components are somewhat differently arranged.
