Abstract: 851,048. Semi-conductor devices. ENGLISH ELECTRIC CO. Ltd. March 21,1957 [March 22, 1956], No. 8974/56. Class 37 In a rectifier unit comprising an element of the extended area rectifying contact type, each element is located between two members with which cooling fluid, flowing through passages in the unit, is in heat-transfer relation. As shown, a rectifying element, comprising a base electrode (not shown) and a disc 17 of n-type germanium on one surface of which is disposed a partly diffused disc 18 of indium, is clamped between the end faces of copper members 15, 16, which are located within tubular brass sleeves 10, 11, respectively, and which have portions of their curved surfaces rebated to form with sleeves 10, 11, annular spaces 19, 20, which intercommunicate via brazed outlet pipes 25, 26 and a flexible pipe 27. Member 15 has a tapped hole 21 and member 16 has a complementary integral projecting threaded stud 22 which has a common blind axial bore 23 with member 16. The hole 21 and the bore 23 communicate at their ends nearer the rectifying element with the annular spaces 19, 20, via radial passages 24. The rectifying element is sealed within a glass tube 12 held between metal cups 13, 14, on sleeves 10, 11. In operation, a number of units may be connected in series, the threaded stud 22 of one unit being screwed into the tapped hole 21 of the next, and cooling fluid, usually water, is fed into bore 23 of the lowest unit, an outlet pipe being connected to the hole 21 in the uppermost unit. It is stated that it may be possible to omit the base electrode and to solder the germanium disc directly to member 16. The Provisional Specification states that the flexible pipe 27 is made of conductive rubber or a similar substance and acts as an equalising resistor to assist the even distribution of reverse potential across each of a number of series connected units; alternatively, the pipe may be made of an insulator such as rubber, polythene, or polyvinylchloride, with a spiral of resistance wire within or without the pipe. The last joint made during construction of the unit is that between cup 13 or 14 and the corresponding sleeve cooling fluid being passed therethrough while the cup is heated, as by induction, so that when it cools pressure is exerted on the element. Specifications 851,043 and 851,047 are referred to.

Title: Improvements in or relating to speed indicators for motor vehicles
IPC: G01P3/16
Filed: 1934-03-29
Abstract: 424,104. Speedometers and odometers. KIENZLE TAXAMETER UND APPARATE AKT.-GES., Villingen, Schwarzwald, Germany. March 29, 1934, Nos. 9784, 9785, and 9786. Convention dates, Dec. 14, 1933, Dec. 30, 1933, and Dec. 30, 1933. [Class 106 (iii)] The speed of a motor vehicle is indicated, a maximum speed indication or alarm is given, odomoters, both non-adjustable and trip, are operated, and records of the polar diagram type are made of the instantaneous speed, average speed and running times, by means of an apparatus in which the front part or cover 1, Fig. 5, is hinged to the back part 3, Fig. 2, and carries a trip odometer and a record card secured to a disc rotated by a clock, the rest of the mechanism being carried by the back part. The main vertical driving shaft 6 rotates through gearing 7, 8, the shaft 9 of a centrifugal speed indicator in which a rack 16 is adjusted longitudinally along the shaft according to the speed. The rack 16 operates gear members mounted on the axis 18 so as to adjust the pointer 22 over the dial. One of these gear members adjusts vertically a slide 36 carrying a spring arm 33 with a stylus 31 which traces on the record card a record of the speed at any time. To warn the driver when a predetermined speed is attained, the dial is illuminated or some change in the character of the illumination, such as a colour change, is brought about by a disc which is mounted on the axis 18 and closes a spring contact 25 so as to complete or vary circuits through lamps behind the dial. This disc 28, Fig. 3, is adjustably mounted on a gear member associated with the speed indicator and is formed with a wedge-shaped part b which directly actuates the spring contact 25 at a given speed. An audible signal may be given. The disc may be reversed so that the part b is disengaged from the contact 25 when a given speed is attained. The running time or rest and motion record is made by a stylus 44 carried by a spring arm on a lever 41 pivoted at 40 and carrying a weight 39 which vibrates between stops 42, 43 when the vehicle is in motion. A thick line is then traced on the rotating record card. A record of running distance against time is made by a stylus 49 in the form of a zig-zag line on the rotating card, the stylus being carried by the end of a lever which is oscillated by a cam driven from the main driving shaft 6 through a train of gearing. An odometer 45 is also driven from the shaft 6 through the same gearing. The trip odometer carried by the cover 1 is driven, when the cover is closed, by an Oldhams coupling and a coupling member 52 geared to the main driving shaft 6. The shaft 6 may be driven from the side or rear through worm or bevel gearing enclosed in an additional casing bolted to the main casing.
