Abstract: 443,484. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. May 28, 1934, No. 15779. Convention date, May 27, 1933. [Class 39 (i)] In a method of protecting Braun tubes which are to be fitted into closed apparatus, the tube immediately after manufacture is fitted into a container having a front wall of glass, preferably shot-proof, and so constructed that in the case of collapse of the tube no glass splinters are flung out, and the tube is transported and fitted into television or other apparatus together with the container. Preferably the arrangement is such that the tube cannot be released from the container without damage to the container or tube. Injury to unskilled persons tampering with the tube is thus avoided. In the example shown, a metallic container is composed of two cylindrical portions 2, 3 in which the Braun tube is supported by bearing pads 7, 8, and an annular pad 4 which rests against a bearing ring 5 secured to the container. A glass front 6 is pressed against the bearing ring by a ring 11 which is either removably connected by a screwed or bayonet joint or is permanently welded to the container. Air-holes 10, covered with wire mesh, are provided to allow entry of air if the tube is broken. A rubber pad may be provided between the glass 6 and the ring 11. Circuit connecting means project from the end of the container, as shown. The container may be of magnetic material, such as sheet iron of ¢-1 mm. thickness, to screen off external magnetic fields. The container may alternatively be shaped to the form of the tube.

Abstract: 1167054 Cooling cables SIEMENS A G 6 April 1967 [6 April 1966 19 April 1966] 15838/67 Headings H1A and A4D An electrical transmission cable comprises a  conductor surrounded by thermal insulation, including an evacuable cavity, in turn surrounded by electrical insulation. As shown in Fig. 1, a tubular, ultra-pure aluminium conductor 1 has a cavity 2 for the passage of a coolant, such as gaseous helium. Thermal insulation is provided by the evacuable cavity between composite plastics corrugated tubes 3, 4, which have a mirror finish on the sides adjacent the cavity and which are spaced apart by helically extending plastics strips 5. The outer surface of tube 4 has a semi-conducting coating 6, such as metallized or carbon-loaded paper, connected to conductor 1 and electrical insulation inside protective jacket 8. The outer tube 4 may be of metal, or both tubes may consist of helically wound metal strips sealed with plastics tape Figs. 4a, 4b (not shown). The low temperature conductor may be built of a large number of insulated individual cores whose radial positions vary along the length of the conductor Fig. 3 (not shown). In a super-conducting cable Fig. 2 (not shown) the conductor comprises a steel tube (9)  insulated from a super-conductive coating (10) and the cable is disposed inside a pressure tube (11) with oil under pressure passing through the gap between insulation 7 and tube (11). In another embodiment, shown in Fig. 5, the cable is subdivided into tubular component elements 21, each having a large number of cores, and cooling channels 22. A helium-tight plastics tube 23 with glass fibre tape reinforcement 24 surrounds elements 21 and prevents leakage of gas into the evacuable cavity 25. The electrical insulating tube 26 has semi-conducting layers 27, 28 and a protective jacket 29 surrounds tube 26. The individual conductors of component cables 21 may be disposed around a metal tube (30), Fig. 6 (not shown), or cables 21 may be disposed around a single elliptical metal tube (31), Fig. 7 (not shown).

Title: Improvements in or relating to the cooling of air and gases for the purpose of condensing vapours therefrom
IPC: F25D21/04
Filed: 1927-06-22
Abstract: 294,354. Frõnkl, M. June 22, 1927. Cooling gases, tubular apparatus for; rime, removing.- In apparatus for drying air for blast furnaces and other gases by refrigerating, reversible cold regenerator chambers e<1>, e<11> are arranged in front of and behind the evaporator of a refrigerating machine and are adapted to be changed over so that each chamber in turn takes up cold from the dried gas and then returns this cold to the incoming moist gas. The regenerator chambers may be filled with metal strips, and after one chamber has been heated to atmospheric temperature by the incoming gas, further gas is admitted in order to dry off the condensed moisture and avoid moistening the dried gas on reversal. Compressed ammonia gas passes alternately at h<1> or h<11> into one or the other of the devices a/b or b/a which act alternately as condenser and evaporator. From the condenser b/a, the liquefied ammonia passes through a throttle valve d into the evaporator a/b. The moist air, entering at f<1>, flows through the regenerator chamber e<1>, where some of the moisture condenses and freezes on the metal strips, and passes by pipe 1<1> to the evaporator a/b where the rest of the moisture is removed. The dried air then passes by pipe 2<11> to the regenerator chamber e<11> where it lowers the temperature of the strips and leaves at f<11>. When the chamber e<1> has attained atmospheric temperature and has been dried, the air valves are reversed by a compressed air or electrical timing device g<1> so that the moist air enters the chamber e<11> and the dried air leaves through the chamber e<1>. The change-over for the evaporator and condenser, by a timing device g<11>, takes place earlier than reversal of the air valves to allow time for the cooling off of the condenser and the freezing of the residual moisture. Melted rime and moisture is withdrawn at k<1>, k<11>, p<1>, p<11>. In a modification, the refrigeration is continuous in an evaporator in two parts alternately sprayed with brine or lye for removal of rime, the part undergoing spraying being that part adjacent to the discharging regenerator cham. ber. The brine or lye is concentrated and reused.
