Title: Time-piece
IPC: G04C3/06
Filed: 1956-04-25
Abstract: 825,856. Clocks. BRANDT & FRERE S. A., O. L. April 25, 1956 [April 26, 1955], No 12632/56. Addition to 763,427. Class 139 In an electric timepiece the maintaining circuit of the balance 1, Fig 1, includes an electronic switch e.g. a transistor 12 connected as shown in Fig. 2 to a pick-up coil 14 and an impulsing coil 13 which co-operate with a magnet 9 on the balance 1. The transistor circuit operates as a blocking oscillator.

Title: A process for use in the production of crystalline boron phosphide
IPC: H01L21/00
Filed: 1963-03-29
Abstract: Crystalline boron phosphide is prepared by contacting phosphorus vapour with boron phosphide at a first region in a reaction system, passing the gas thereby formed to a second region in the system where crystalline boron phosphide is deposited from the gas phase, the temperature at the first region being at least 530 DEG  C., the temperature at the second region being lower than that of the first region, and the temperature difference between the two regions being at least 30 DEG  C.  The process may be carried out in an open, partially closed or completely closed reaction system.  If an open system is used, phosphorus vapour can be passed over the boron phosphide by means of an inert carrier gas, e.g. helium.  In a partially closed system, phosphorus vapour is drawn over the boron phosphide by means of pump suction.  Doping substances may be mixed with the phosphorus vapour or boron phosphide starting material to produce crystalline boron phosphide of a prescribed conductivity. The process may be repeated using different doping substances to produce boron phosphide monocrystals having layers of diffferent conductivity.  In an example, polycrystalline boron phosphide and red phosphorus were placed in separate alumina boats at each end of an open alumina tube.  The phosphorus was heated to 400 DEG  C. and the boron phosphide to 1500 DEG  C.  Helium was passed through the tube such that monocrystalline boron phosphide was deposited on the walls of the tube, see Fig. 1 (not shown).  The crystals were removed mechanically or by treatment of the tube walls with HF.

Welding.-In a machine for automatically butt - welding three co-linear parts of conductors 2, Fig. 1, such as miniature lead wires with intermediate parts 4 of material suitable for sealing in the base 1 of a radio valve, one end part 5 consisting of a cut-off length of wire stock is butt-welded to the intermediate part 4 consisting of a second cut-off length of different wire stock and the free end of the intermediate part is then butt-welded to a valve pin 3. Copper-clad nickel-iron alloy wire 7, Fig. 6, suitable for sealing in glass, is fed from a spool 8 by a reciprocating gripper 34 through a guide 10, to grippers 12 on a slide 14, cut to length by a knife 13 and carried by the slide 14 to a position between a butt-welding plunger 19 and a weld slide 41. The weld slide has conducting grippers 40 carrying a cut-off length of lead-wire 36 fed through a die 39 from a spool 35 by a reciprocating gripper 38. The wire is cut to length by a fixed knife 42 which engages the front face of the die 39 and which is reciprocated across the path of the wire. The parts are then buttwelded between the plunger 19 and weld slide 41 after which the grippers 12 automatically release the wire and the weld slide 41 is withdrawn, carrying the two welded parts in the grippers 40. A valve pin 9, Fig. 7, is then automatically fed into position between the welded parts and the welding plunger 19 by a second pair of grippers 15 on the slide 14 and is similarly welded. The grippers 40 then release the welded assembly and the weld slide 41 is further withdrawn, permitting the slide 14 to carry the assembly to an ejection station opposite a plunger 28, as it moves to repeat the series of operations. The valve pins 9 are fed to the grippers 15 from a hopper (not shown) in a slot, 26 in an arm 27 which is reciprocated over the top surface of a block 6 and passes over a " V " groove 25 into which the pins are successively dropped and from which they are successively pushed forward into the grippers 15 by the reciprocating plunger 28. All the slides and welding-current switches are actuated by cams on interconnected drive-shafts and the grippers for the wire are solenoid-actuated under the control of switches actuated by further cams on the drive-shafts.

The Figure shows a resistance-capacity coupled amplifier of the type employing valves of high magnification and high anode resistance of the order of megohms, in which separate filters 18, 19 and 20, 21 are provided for the valves 7, S. As the anode currents of the valves 7, 8 are small since these are voltage amplifiers the voltage drop in the resistances 18, 20 will be of the order of 3 volts. A filter of known type may be connected between the supply and terminals 1, 2 if necessary and each of the separate filters may supply more than one valve.

Abstract: 854,543. Sorting letters. THRISSELL ENGINEERING CO. Ltd. April 27, 1959 [April 29, 1958], No. 13577/58. Class 78 (1). In a letter-sorting machine a device is provided for determining whether a letter has sufficient flexibility to pass through the machine without becoming jammed. The device comprises a series of rollers 4 ... 9 between which the letter passes if it can assume an arcuate shape. The rollers 4, 6, 8 rotate on fixed axes, but the axes on which the rollers 5, 7, 9 rotate are mounted on springs 11, 12, 13 secured to an arm 14 pivoted at 15. If a letter cannot assume the arcuate shape, it causes displacement of the rollers 5, 7, 9 and a micro-switch 16 to be operated by a spring 17 to switch off the motor driving the rollers and also to give a visual or audible signal. When the cam 18 is rotated by an attendant, the arm 14 is lowered and the letter can be removed. The letter is taken from a pile by a suction device 3 and conveyed to a position to be engaged by the rollers 4, 5.

Abstract: 1299435 Battery-charging systems ALKALINE BATTERIES Ltd 11 March 1970 [14 March 1969] 13601/69 Heading H2H A method of charging electric storage battery cells comprises passing a charging current through the cell and periodically reversing the direction of the current through the cell, the reversals being produced automatically and each charge period and each discharge period being of predetermined duration. The circuit for charging the battery 52 from a D.C. source 50 consists of an A.C. source 30, a bridge rectifier 32, a voltage regulator including a Zener diode 36 a unijunction transistor 10 in a circuit for timing the battery charging period and a unijunction transistor 20 in a circuit for timing the battery discharging period. Initially relay coils 17, 27, 40 have their contacts 17/1-17/3, 27/1, 27/2, 40/1-40/4 in the positions shown and the battery 52 is charged by the source 50 as a capacitor 13 charges, a switch 45 being closed. When the capacitor voltage reaches the threshold voltage of the transistor 10, the relay coil 17 is energised thus closing the contact 17/2 to initiate the charging of a capacitor 23 and closing the contact 17/3 to energize the relay 40 thereby closing the contacts 40/3, 40/4 and reversing the connections of the battery 52 to the D.C. source to commence discharging the battery. When the voltage across the capacitor 23 reaches the threshold voltage of the transistor 20, the relay 27 is energized thus opening the contacts 27/1, 27/2 to de-energize the relay 17. The relay 40 and the battery discharging time circuit are therefore also de-energized and the contacts 40/1, 40/2 are closed to re-connect the battery 52 for a charging period.

[Also in Group XIII] In an air heater, in which a mixture of fuel and air, drawn into a combustion chamber 13 periodically through a non-return valve assembly 33, is fired in that chamber by the high temperature of the latter and a flame tube 14 receives the resultant hot gases, a fan 18 impelled by a turbine 47 driven by the gases from the flame tube directs a stream of air, uncontaminated by the combustion gases, over the combustion chamber through an air tube 10 which surrounds it. The outlet 17 for the hot gases is outside the air tube 10. In the form shown, the non-return valve assembly comprises saucer-shaped valves 33 fitting in holes in a plate 32, upward movement of the valves being limited by metal gauze 34. Initially, a current of air supplied by a hand-driven fan 39 is mixed with fuel from a reservoir 26, enters the combustion chamber 13 past the valves 33, and is fired by a sparking plug 43 energized by a magneto 42 which is also hand-driven. The explosion closes the valves 33, which re-open when the gases have flowed along the tube 14, so that a further mixture can enter. When the walls of the chamber 13 are hot enough, operation of the fan 39 and magneto 42 is stopped. The heater may be mounted on skids carrying rubber-tyred wheels.
