Abstract: 1,160,880. R.f. power measurement. WAYNE KERR CO. Ltd. March 15, 1968 [March 15, 1967], No. 12219/67. Heading G1U. R.f. power in a transmission line or waveguide is measured by dissipating at least part of it in a terminating load to the line or guide and detecting the resulting rise in temperature. The load incorporates a film of insulating material 20 having on its surface facing the direction from which the power is incident conductive material 22, 23 forming a resistive load. On the other surface of the insulating material thermo-electric strips 24, 25; 26, 27 forming thermoelectric junctions for measuring the temperature of the films are arranged and these strips have impedance substantially greater than the conductive material. To measure power in a coaxial line of impedance say 50 ohm, the line is terminated by a unit 10 in which a connector 12 to the inner of the coax is flared out into a cone 14, having an impedance of 49À5 ohm, in which the greater part of the power is dissipated. The termination is continued by an inner metal tube 16 separated from an outer one 17 by a thin layer of PTFE to provide a low impedance thermally isolating section between the cone and the insulating disc 20, which is of mica. The conductive areas 22, 23 are of goldcopper alloy and present an impedance of about 0À5 ohm to finally match the coax line. The thermocouples are of antimony and bismuth telluride and have impedances of the order of 500 ohms. They have gold contacts 30-33 at their ends and are covered by a protective material e.g. silicon dioxide.

Abstract: 985,326. Washing granular materials. KLOCKNER - HUMBOLDT - DEUTZ A. G. March 30, 1962 [March 30, 1961], No. 12276/62. Heading B2H. A method of regulating the withdrawal of pulp from two or more thickeners 1, 2 and 3 is characterized by the pulp being withdrawn from each thickener in two separate component streams, the flow of one component stream from each thickener being regulated depending on the density of the pulp in the associated thickener and of the other component stream being regulated depending on the sum of the flow from all the thickeners. A device for carrying out this method comprises a density measuring device 18, 19, 20 which controls the flow of the first component stream 1a, 2a, 3a through setting members 12, 14, 16 into a tank 10 in which is a volume measuring device 21 which regulates the flow of the second component streams 1b, 2b, 3b by means of setting members 13, 15, 17. All the setting members, 12 to 17, consist of a slide or other valve, a control head and a motor which sets the valve and are constructed to give a minimum flow of the component streams, 1a to 3b, independently of regulation. The density devices 18, 19, 20 and the volume device 21 consist of dip-tubes through which compressed air flows. An optical or acoustic signal may give warning of high levels in the tank 10. An alternative arrangement illustrated in Fig. 2 (not shown) withdraws the two component streams from each tank through a Y-tube attached to a single outlet instead of from two separate outlets as in Fig. 1.

Abstract: 1,254,279. Loading and trimming loose bulk material. ASSOCIATED BRITISH MALTSTERS Ltd. 5 May, 1969 [14 March, 1968], No. 12425/68. Heading B8E. Loose bulk material is loaded into a container 11, Fig. 1, by an open-bottomed screw conveyer 12 which moves to and fro along the container, is fed with material by a hopper 22 and a further screw conveyer 19, and has adjustable scrapers 16, 17 which level the material as the conveyer 12 moves over the container. The hopper 22 is fed from spouts 23, Fig. 2, which are opened by levers 25 and a cam 24. With the conveyer 12 at one end of the container, material is fed in until the full width of the container has been supplied. At this point the material coming along the conveyer raises a flap valve 18 and operates a switch which moves the conveyer step-wise to the next position along the container. The valve 18 may be placed other than at the end of the conveyer. As the conveyer moves step-wise along the length of the container the latter is filled up to a level determined by the bottom of the scraper 17. On the return run the conveyer moves and feeds material continuously and the scraper 16 smooths off the material at its final level. The vertically displaceable levers 25 may be replaced by swinging arms which are displaced to open the spouts.
