Title: Improvements in or relating to pí¬n junction rectifiers
IPC: H01L21/00
Filed: 1957-03-15
Abstract: 847,524. PN junction rectifiers. GENERAL ELECTRIC CO. Ltd. March 13, 1958 [March 15, 1957], No. 81714/57. Class 37. A rectifier assembly comprises a PN junction rectifier formed by alloying an activator metal mass to a semiconductor body, mounted within an envelope made of two metal parts sealed together. The rectifier is mounted on one of the parts and a connecting member the crosssectional area of which is nowhere less than 5 % of the PN junction area extends through but is insulated from said part to make contact with the metal mass. In the manufacture of one embodiment (Fig. 4) superposed discs 37, 36, 35, 34 of N type germanium, solder, iron-nickelcobalt alloy and solder respectively are clamped by a split cylinder 42 between two halves of a graphite mould 38 on an offset boss 29 extending from the base of a flanged copper cup 28. The end of a J-shaped copper connector sealed through a glass bead in the base of the cup is disposed adjacent to the germanium disc. The assembly is mounted on a trolley 6 (Fig. 1) in an elongated quartz chamber 1 provided with heating coil 3 and cooling duct 4 which at equilibrium produce a temperature which gradually increases from 300 ‹C. at one end of the chamber to 500 ‹C. at the centre and then falls rapidly in the cooled region. The trolley is gradually moved to the centre of the chamber where its presence photoelectrically actuates a dispenser 14 to discharge a metered amount of molten indium at 400 ‹C. into the mould 38. The indium dissolves some of the germanium and when the assembly passes into the cooled end of the chamber the germanium recrystallises to form a PN junction, the residual indium solidifies to bond connector 32 to the germanium body and the solder to bond the germanium to boss 29 via disc 35. After removal of the assembly from the chamber and dismantling of the mould the enlarged flange of a second flanged copper cup otherwise externally similar to cup 27 is cold welded in dry nitrogen to the flange of cup 27 to form a sealed casing for the device. The device may be air cooled or, if the boss is formed with a water passage by flow of fluid therethrough. Specifications 787,389, 817,362, 831,085 and 831,086 are referred to.

Title: Improvements in or relating to data processing apparatus
Inventor: FREEDMAN ARYE LEIB
IPC: G06F13/26
Filed: 1961-03-09
Abstract: 983, 508. Data transfer arrangements for electronic computers. DECCA Ltd. June 8, 1962 [March 9, 1961], No. 8733/61. Heading G4A. Peripheral units 11-14 of a central computer 10 produce signals on lines 15-18 when they are ready for data transfer. When the computer 10 is able to effect this it resets all flip-flops 24-27 over line 28 and provides a pulse on line 23 which sets the flip-flops corresponding to the waiting units, and thus the pulse on line 23 will be diverted from the chain of gates 30-33 to the upper set of and gates by the first waiting unit. This informs the computor of the highest priority unit demanding data transfer (unit 11 having highest and 14 lowest priority). Fig. 2 (not shown) illustrates a modification in which the setting of any flip-flop re-sets all those of lower priority; the computor waits until this is done before acting on its 'transfer demand' input signals. Fig. 3 (not shown) shows a further modification in which 16 such flip-flops are notionally arranged in a square matrix of rows and columns; two separate circuits similar to that of Fig. 1 are provided for rows and columns so that the unit receives signals from one of four row lines and one of four column lines representing the address of the highest priority unit calling.

Patent GB-372491-A (GB)
Title: Improvements in or relating to stand-by steam power plants
IPC: F01K3/02
Filed: 1931-03-21
Abstract: 372,491. Power-generating systems. RUTHSACCUMULATOR AKTIEBOLAG, 1A, Eriksbergsgatan, Stockholm. March 21, 1931, No. 8802. Convention date, April 5, 1930. [Class 122 (iii).] Comprises a stand-by, steam power plant with an accumulator and a boiler k which, after interruption in the main-power supply, starts with accumulator steam, and, after the starting of the stand-by boiler k, runs with boiler steam. The power-generating unit has a number of inlets connected to the live-steam pipe and to the accumulator steam pipe. On starting the steam production from the boiler, the lower stages of the power-generating unit are out off so that live steam is utilized in the stage or stages adapted to its pressure which is higher than the accumulator steam pressure. In the plant shown in Fig. 3, a steam chamber f is arranged between the overflow valve u and the pipe l. When the boiler has reached its full pressure, the valve u opens and the vessel f is filled with pressure steam. On opening the cut-off valve v by hand, the sudden supply of steam causes the closure of the lower turbine stages and the accumulator non-return valve. In the plant shown in Fig. 4, boiler steam is supplied to the turbine between the branch for the low-pressure stages and the first stage inlet. When valve u opens stage 1 is supplied with boiler steam. As the turbine speed increases, the lower stages are cut out and thus the accumulator supply. In a further modification, when the boiler commences to give steam, this passes through a supplementary turbine or stage prior to joining up to the accumulator main-turbine connection. The governor cuts off the lower stages so that the steam from the supplementary turbine or stage can only enter the first stage. The accumulator is cut off by a non-return valve. The Specification as open to inspection under Sect. 91 (3) (a) comprises a modification wherein a nozzle-regulated turbine is used. When an interruption occurs the governor opens the turbine stages 1, 2, 3 one after another to the accumulator; the steam passing non-return valves to these stages. Pressure-controlled valves in the boiler-steam supply, opened one after the other, supply the stages as they are opened by a pressure-responsive governor, the speed governor closing the lower stages as the speed increases. The pressure governor may affect the speed governor. This subject-matter does not appear in the Specification as accepted.

Title: Process and apparatus for making sheet glass
IPC: C03B15/18
Filed: 1925-04-03
Abstract: 235,146. Pittsburgh Plate Glass Co., (Assignees of Slingluff, H. G.). June 5, 1924, [Convention date]. Drawing.-Relates to a process of drawing sheet glass in a continuous strip and consists in preventing the sheet from becoming narrower, as the draw proceeds, by applying a shielding, heatabsorbing device above the portion of the glass from which the edge is drawn, and causing the edge of the sheet to adhere to this device during the draw. The sheet 6 is drawn upwards by suitable mechanism from a mass of glass 2, Fig. 2, contained in the forehearth 16 of a tank. The shielding device consists of a dished metal plate 14 provided with a radial slot 15, Fig. 3. The member is supported close to, but preferably not in contact with, the surface of that part of the metal 2 from which the edge of the sheet is drawn. In use, the members 14 are heated and placed in positions such that the edges of the sheet are drawn through the slots 15. The edges of the sheet adhere to the members, as shown in Fig. 3, and are retained in position during the draw. The temperature of the members 14 is maintained by heat radiated from the mass of glass, and the presence of the heated members tends to maintain an even temperature in the portions of the metal from which the edges of the sheet are drawn. The member may be flat or may be arranged with its concave side downwards. In some cases, the member may be arranged with its undersurface in contact with the glass.

Abstract: 526,608. Clocks. SIEMENS BROS. & CO., Ltd. , MILLER, W. A., and HENSLER, B. A. March 22, 1939, No. 9054. [Class 139] [Also in Groups XXXV and XXXVII] A motor comprising field coils M1, M2 energized in succession from a D.C. source, under the control of a commutator device m1, m2, operated by the motor, is operated at constant speed by connecting the field coils also to the contacts ac of a relay energized from an A.C. source of constant frequency. The relay ac is effective to cause energization of both field coils once during each half-cycle of the A.C. supply. For this purpose a rectifier MR is connected across the coil of the relay ac. A circuit R.K. may give smoother stepping operation of the motor. In a modification, Fig. 2, the relay ac operates in synchronism with the A.C. supply and its contacts merely make and break a circuit connecting one field in parallel with the other. The application of the invention to an instrument for measuring the time of response of a valve or the durations of an earth impulse is described with reference to Fig. 3 (not shown). The motor drives contact banks of a switch, and is started up at the commencement of the time interval to be measured and stopped at the end thereof. In this position of the switch corresponding lamps indicating the time interval are lit. Specifications 385,692 and 405,436, [both in Group XXXVII], are referred to. Specification 388,173, [Group XXXV], also is referred to.
