Title: Zone melting apparatus
IPC: C30B13/30
Filed: 1958-04-22
Abstract: <PICT:0844813/III/1> <PICT:0844813/III/2> In a method of zone-refining a rod of semiconductor material 10 (Fig. 1) by passing a molten zone along the rod, the molten zone 38 is produced by an induction coil 36 and is displaced upwards with respect to the coil 36 (see Fig. 2), whereby the induction field about the coil exerts a levitational force upon the zone permitting the treatment of a rod of greater diameter than if the molten zone is held in position by surface tension alone.  The molten zone is displaced by decreasing the heat flux through the upper liquid-solid interface by heating the upper part of the rod 10 with a heater coil 40, and by increasing the heat flux through the lower liquid-solid interface by cooling the lower part of the rod with a water-cooled jacket 50.  The same effect is obtained if direct current is passed through the rod so that Peltier heat is generated at the upper interface and absorbed at the lower interface, or if the molten zone is moved so that heat of crystallization is released at the upper interface and heat of fusion is consumed at the lower interface.

Abstract: 1,244,284. Moulding cushions. MARLEY TILE CO. Ltd. 4 March, 1970 [11 March, 1969], No. 12826/69. Heading B5A. [Also in Division A4] A method of producing moulded foamed plastics cushions comprises dividing a mould into two compartments by a sheet of air-permeable material compatible with the foamed material, through which gases can escape from the mould during foaming, and allowing foamed plastics forming compositions to expand in the compartments, whereby an article comprising a layer of air permeable material sandwiched between cushion portions of foamed plastics, is produced. The air permeable layer is held around its periphery between a base and closure member of the mould to form the compartments. Equal amounts of foamed plastics forming compositions are introduced into the compartments and the mould is shaped to form cushion portions of equal size and with bevelled portions on either side of the air-permeable sheet. The compositions may be polyurethane foam forming composition, polyurethane polyether or polyester foam forming composition, or a composition based on vinyl chloride homopolymers or copolymers of a polyethylene. The air permeable material is formed of air permeable paper, polyester, polyvinyl chloride material or open cell foamed polyurethane, from 0À25 to 0À5 inch thick, and preferably 0À375 inch thick.

Title: Improvements relating to automatic telephone systems
IPC: H04Q3/62
Filed: 1940-08-12
Abstract: 540,201. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., CHRISTIAN, D. A., and HENSLER, B. A. Aug. 12, 1940, No. 12886. [Class 40 (iv)] In a system in which privileged subscribers are provided with keys for setting up frequently wanted calls over individual selectors without passing over the normal selecting apparatus, the talking circuit is switched through at the selector when both subscribers have removed their receivers, provision being made for ringing the calling as well as the wanted subscriber. If the wanted line is busy, the privileged caller may receive incoming calls while the connection remains in a waiting condition, or he may elect by keyoperation to break in or to cancel the connection. Momentary actuation of one of the keys MK operates one or more of relays X-Z in series with BD. Release relay B energizes, switching the line over to the individual selector and connecting up start relay S, whereupon the selector moves to the position marked by X-Z. Ten markings are provided, and if the selector is required to give access to more than 10 subscribers, an additional key-controlled relay V is provided to switch in a second marking wiper when necessary. When the selector is set, TA, TB disconnect S, BD and the marking relays. If the wanted subscriber is idle, test relay H pulls up, lighting lamp GL, and ringing current of a distinctive character is applied over TR, which responds on reply and connects up feed relay D, whereupon the calling subscriber is rung over F, which on reply completes the talking circuit and connects up feed relay A. Release relay B is held jointly by A and D. Should the calling subscriber remove his receiver first, F is connected up by A and his ringing is prevented. If the wanted subscriber is busy, BL pulls up on the relapse of S, lighting lamp RL and removing the busy marking applied by B to the calling line. Should an incoming call now be received, cut-off relay K connects the line to the final selector multiple and prevents the operation of H until the call is finished. To break in, the privileged caller actuates key RWK to connect up RW which brings about the operation of F, TR, H. Actuation of cancel key CK causes the operation of CO which disconnects B. If another selecting key is actuated, the operation of BD shunts out BL and B falls back momentarily, after which the fresh call is set up. Specification 355,927 is referred to.

Filed: 1924-05-26
Abstract: 235,702. English Electric Co., Ltd., and Bolton, R. A. R. May 26, 1924. Systems depending on the use of two or more machines.-A dynamo-electric machine in a condition for operating is automatically selected for starting from a group which may include machines not in such a condition. A moving contact travels over a series of contacts 2 - - 5 each of which is connected to an automatic starting means. Associated with each machine is a circuit including one o: a series of solenoids 11 - - 14 controlling stops 6 - - 9 in the path of the member 1 carrying the moving contact. The stop corresponding to a machine is thus placed in the path of the member, under manual or automatic control, when the machine is in condition for service; such control may include a switch on an automatic starter for the machine, a centrifugal switch, or a relay energized by the load current of the machine. The contacts 2 - - 5 may be in a straight line, an arc, or a circle and the moving member may be actuated by a solenoid or a torque motor and through a rack, a ratchet, or a direct coupling; the biassing spring 21 may be omitted. The automatic starting-gears include retarding-devices which prevent starting until the moving member has rested for a period upon any contact. In the example given the selecting device is under the control of a switch 27 controlled by conditions demanding an increase in the number of machines in service. Low voltage in the line, for example, may cause a solenoid 28 to permit closure of this switch, whereupon solenoid 22 is energized and the switch member 1 moved from its rest position 20 over contacts 2, 3-the machines controlled .thereby being in service or out of commission and their stops 6, 7 being therefore retracted-and held over the contact 4 by the stop 8 till the corresponding machine has started up and the line conditions have caused switch 27 to open. The member 1 then returns to its rest position and the stop 8 is retracted. The stops 6 - - 9 may themselvesserve as the switch contacts.

A circuit for controlling the operating and release limits of a relay comprises a resonant input circuit such as L1, Cl coupled to a relay 4 via an amplifier and rectifier and a feedback circuit including a non-linear resistance such as diode 8 inductively coupled to the resonant circuit so as to influence its impedance. As shown, the diode 8 is normally biased conductively by the source 6 so that the circuit L1, Cl is damped. When the input voltage E exceeds a value E2, the rectified voltage across the resistor 5 overcomes that of the source 6 and a rapid increase in output occurs, energizing the relay 4, which will remain energized until the input falls to El. The operating and release voltages may be varied together by variation of the bias voltage 6. The operating voltage may be increased by adding resistance to the diode circuit. Variations in the operating and release voltages with temperature may be minimized by replacing the source 6 by a thermistor fed from a voltage divider.
