Abstract: 882,760. Cooling liquids. FLETCHER & CO. Ltd., GEORGE, and MURRAY, C. W. July 14, 1960, No. 24503/60. Class 29 In a liquid cooler particularly for crystallising massecuite, in which the liquid flows in countercurrent to the flow of cooling water through a series of hollow fins mounted on a common hollow rotatable shaft, the water is distributed to groups of fins in succession so that there is a steady increase in fin temperature throughout the length of the tank. As shown, the flow of water along segmented duct 17 or 18 is diverted by each plate 19 so that the water enters a pair of hollow fins 21, the outflow from the fins entering the other duct 18 or 17. The water flow path thus alternates between the ducts 17 and 18 until the last segment of duct 17 is reached. This communicates with a central return duct 24 along which the water flows to outlet pipe 16. The massecuite flows from inlet 12 to outlet 13. An assembly of tanks 11 may be arranged so that in adjacent tanks the flow of massecuite and cooling water are both reversed (Fig. 7, not shown). Each fin 21, Fig. 4, has an internal water circulating labyrinth 21B.

Title: Improvements in or relating to tunnel diodes
IPC: H01L27/00
Filed: 1965-06-11
Abstract: 1,103,025. Semi-conductor devices. SIEMENS & HALSKE A.G. 11 June, 1965 [12 June, 1964], No. 24697/65. Heading HlK. A semi-conductor device comprises a tunnel junction between two regions having main electrodes joined by an external coupling loop, and having an auxiliary electrode on one of the regions. The device is arranged so that it can be stabilized on the negative resistance part of its characteristic by applying a voltage to the auxiliary electrode so that the P.D. due to a current through the base resistance produces the bias voltage for the junction. This reduces the effective inductance of the device. As shown, Fig. 6, the device comprises a tunnel junction 3 formed in a mesa between alloyed electrode 2 and a base region 1. Electrode 5 is soldered on to the lower face of base region 1 and auxiliary electrode 6 is provided on the upper face of base region 1. The device is mounted in a rectangular waveguide 8 which forms a conductive path 9 between electrodes 2 and 5. A voltage source U 1  is connected between electrode 6 and waveguide 8, the resulting current through base region 1 producing a voltage drop which forms the effective bias supply for the tunnel junction. In an alternative arrangement, Fig. 3 (not shown), the waveguide is replaced by a conductive loop, having a low inductance, which may be a transmission line. The base region may be arranged to provide the required base resistance, which may be made voltage variable, by diffusing impurities into both faces of a high resistivity substrate (III), Fig. 7 (not shown), to form degenerate regions (I) and (II). Alternatively the base region may comprise a degenerate wafer (IV), Fig. 8 (not shown), on which is epitaxially deposited a high resistivity layer (V). Electrode 5 may make a rectifying contact with base region 1 and this may also form a tunnel junction.
