Abstract: 749,019. Point contact transistors. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 25, 1954 [Sept. 2, 1953], No. 24273/53. Class 37. An hermetically sealed transistor comprises emitter and collector electrodes 7, 8 mounted on or forming extensions of a pair of leads 2, 3 passing through a metal disc 1 via glass to metal seals 4, 5, the ends of the electrodes being bent over towards the disc to contact a flake 9 of semi-conductor material, e.g. Ge, mounted on a metal base 10 located between the leads and supported from the disc, and a metal cup 12 the rim of which is sealed by welding or soldering to the disc in a region 13 beyond the seals. The base 10 is formed with a plane face adjacent the upstanding arm of L-shaped member 11 the base of which is secured to the disc. After assembly of the electrodes the pressure of the electrodes on the flake is adjusted by adjustment of the vertical position of base 10 by means of a jig. Base 10 is then resistance welded to member 11, its heat capacity preventing a rise of temperature harmful to the flake. The cup 12 is then resistance welded at its flange to a ridge 13 at the edge of the disc, the remoteness of this point from flake 9 preventing harmful rise of temperature thereof. In an alternative arrangement, Fig. 4, the wafer is mounted on the central part of a zig-zag strip 14 to the underside of which base 16 is secured. Adjustment of electrode pressure is made in this case by horizontal movement of the feet 16. The electrodes 7, 8 may be in the form of ribbons cut from sheet material.

Aug. 14, 1930, No. 24384. Convention date, Aug. 16, 1929. [Class 39 (i).] A compass, particularly for aircraft, indicates direction by the deflection in the earth's magnetic field of slow-speed cathode rays, i.e. rays corresponding to a voltage of the order of 100 to 150 volts. A cathode-ray tube similar to a Braun tube, but without deflection plates, is arranged with its axis RR horizontal. If the aircraft is flying in the direction of the horizontal component Hh, i.e. towards the north, the cathode ray is shown at the point N of the fluorescent screen. An easterly course is indicated by the ray at the point 0 of the fluorescent screen. A windrose may be arranged on the fluorescent screen. A contact rim with separate insulated contacts may be arranged in the interior of the tube, the cathode ray closing a relay circuit through the corresponding contact and thereby lighting a small signalling lamp. These lamps may be arranged in a circle so as to reproduce the windrose at a distant point. The cathode-ray tube may be mounted in gimbals to maintain its axis vertical.
