Abstract: 896,109. Reactors. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT VORM: ROESSLER. Sept. 5, 1960 [Sept. 4, 1959], No. 30567/60. Class 39(4). In a reactor in which the fuel and/or breeder material is in the form of small elements, e.g. balls, the elements are guided along a unical spiral path through the core so as to traverse the different zones of neutron flux and hence all the elements become exposed to the same flux. As shown in Fig. 2 the reactor comprises four spiral tubes 21.. 24 nested inside one another, the elements of fuel and/or breeding material passing through the tubes. The tubes are filled with a heat transfer liquid and situated in a liquid-filled core (Figs. 3, 4, not shown). Either liquid may be a sodium-potassium or bismuth-lead alloy, an organic compound or water. The tubes are in heat exchange relationship with the core liquid which may serve both as coolant and moderator. Movement of the elements is obtained by discharging one or more from the lower ends of the tubes and introducing a corresponding number at the top ends. If the density of the elements is less than that of the liquid in the tubes the elements are discharged from the upper ends and introduced at the lower ends.

Title: A Method and Apparatus for Manufacturing Wire and the like
IPC: B22D11/06
Filed: 1967-07-04
Abstract: 1,160,934. Continuous casting machines. BATTELLE DEVELOPMENT CORP. 4 July, 1967 [6 July, 1966], No. 30633/67. Heading B3F. [Also in Divisions F4, G1 and G3] In the continuous casting of products such as metallic wire or strip, molten material M is fed from a reservoir 1 through a pipe 7 and nozzle 10 under constant pressure and temperature conditions to form a convex meniscus at the orifice of the nozzle which is continually wiped away by the upward moving surface of a cooled constant temperature drum 16 on which the material soldifies. At the start of casting a meniscus is formed at the nozzle 10 and the reservoir 1, mounted in a chamber 2 resting on an adjustable support 6, is adjusted vertically and/or horizontally until the moving surface of the drum 16 touches the meniscus and starts to form the continuous product. The chamber 2 includes electrical heaters 5 and 9, thermocouples 14 and 15, and control devices 12 and 13 for keeping the molten material in the reservoir 1 and the pipe 7 at a constant temperature above its melting point. Constant pressure at the nozzle 10 is achieved by either controlling the level of the molten material above the level of the nozzle 10 or by varying the pressure in the chamber 2, e.g. starting at a pressure less than atmospheric and gradually raising it. To keep the level of the molten material constant a piston 29 is gradually lowered into the reservoir 1, or alternatively a bar (43), (Fig. 2, not shown), of the same material as being cast is gradually lowered into the molten material and melted thereby. Detecting electrodes 38, 39 switch off, by means of relay 37, the motor 30 lowering the piston 29 or bar 43 when the level of molten material rises to a predetermined level. The rotating drum 16 is kept at a constant temperature by providing a coolant flow therethrough of water from a bath 18 containing a cold water coil 19, an electric heating element 20 and a thermocouple 26 that keep the water temperature constant. The cast product solidifies on the drum 16 and appropriate take-off means, e.g. roll systems, may be used to separate the product from the drum. The speed of rotation of the drum may be adjusted to control the solidification of the cast product. The shape of the cast product is determined by the shape of the nozzle 10 and a rolling operation may be carried out on the drum 16, by means of a separate roller, to flatten or reduce the thickness of the east product. The drum 16 is cleaned by a wiper 36. Inert gas, e.g. argon, may be provided in the chamber 2. The method of casting may be used to produce aluminium fibres by rotating the drum 16 at high speeds, and for casting materials such as brittle intermetallic compounds or metallic oxides.

Abstract: 1418709 Data processing systems HONEYWELL INFORMATION SYSTEMS Inc 27 June 1973 [27 June 1972] 30658/73 Heading G4A A data processing system comprises a data processor 10, a plurality of devices 50 and logic circuitry in each of the devices for determining the highest priority device ready to make an interrupt request and transmitting the address of this device to the processor. As described when the processor is ready to receive interrupts a request enable signal is provided on line 18 to enable gates 32 in the devices so that an interrupt request signal is generated on line 16 of the bus 11 by any device in which bi-stable 30 is set indicating an interrupt request. A priority network ensures that only gate 40 in the highest priority device requesting access is enabled to transmit the device address since an OR gate in each device, e.g. OR gate 46.3 is disabled if a higher priority device, e.g. device 50.1 or 50.2 requests access. A strobe pulse enters the device address into register 80 at the processor, an interrupt base memory address being added in adder 60 to provide an address for accessing the interrupt service routine associated with the interrupting device. The strobe pulse also resets via gate 38 the bi-stable 30 in the service device. The devices 50 may be magnetic tapes, discs or drums, teletypewriters, line printers, card readers or card punchers.

Title: Improvements relating to circuit arrangements employing semi-conductor diodes
Inventor: STIRLING HAROLD JAMES
IPC: H04Q3/52
Filed: 1960-09-07
Abstract: 994,458. Semi-conductor gating circuits; automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 24, 1961 [Sept. 7, 1960; April 27, 1961], Nos. 30831/60 and 15290/61. Headings H3T and H4K. In a gating circuit using a semi - conductor breakdown device such as a PNPN diode or triode, a rectifier is connected in series with the signal channel and is provided with current bias circuits at each electrode so as to be normally conducting but, when the signal is of such a magnitude that it would otherwise reduce the current to a value below the holding current of the breakdown device, the rectifier becomes non- conducting whereby the holding current is maintained by the path next to the breakdown device. Fig. 4 shows a coordinate switching system in which a telephone channel sp1 is connected through transformer T1, PNPN diode A, limiter circuit BC, PNPN diode P and transformer T2 to an output circuit SP2. The circuit is set to this condition by applying opposite polarity pulses to terminals ts1 and ts1<SP>1</SP> (switch +Vm being made) and to ts2 and ts2<SP>1</SP> so as to cause breakdown of the PNPN diodes, rectifiers being connected to these terminals to prevent the switching pulses being shunted to earth. Further rectifiers, Rsa, Rsb are connected in series with the signal path and biased through circuits such as L2, L1 to be normally conductive. If the amplitude of the signal current is such that the current through PNPN diodes would be reduced below the holding current, the rectifiers Rfa and Rfb become nonconducting and sufficient current is supplied through inductors L1 and L2<SP>1</SP> to maintain the diodes conducting. The inductors could be replaced by the emitter collector path of a transistor arranged as a constant current device so that the operation would be independent of the resistance of the external circuit (Fig. 6, not shown). Double Zener diodes ZD1 and ZD2 are coupled across the input and output transformers to limit the amplitude of the signal. These may each be replaced by a pair of biased rectifiers or series current limiters (Figs. 3b and c, not shown). Inductors 1c and 1d overcome the delay in operation of the Zener diodes ZD1 and ZD2 and inductors La and Lb compensate for delay in operation of the rectifiers Rfa, Rfb due to hole storage. A switch in the path from the battery plus vm. is operated when the path is ascertained to be the one that is to be selected. A further co-ordinate switching arrangement may be located between the switching devices and the terminal elements in which case the vertical control lines of the circuit shown may be connected to the horizontal control line of the additional arrangement, the voltage pulses appearing at the emitters of the diodes in a further arrangement serving as the required switching on pulses for these diodes. In Figs. 2 and 5 (not shown) PNPN triodes replace the PNPN diodes. Specification 994,460 is referred to.

Abstract: 424,948. Retractive switches. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. Oct. 27, 1934, No. 30859. Convention date, Nov. 1, 1933. [Class 38 (v)] A switch for controlling a direction indicator of a vehicle is combined with a press button switch for controlling the horn and arranged at the centre of the steering wheel. The operating handle of the direction indicator switch comprises an insulating disc 6 fastened to a plate 9 which is guided in a plate 10 fixed inside a casing 4 arranged in a recess 2 in the hub of the steering wheel 3. The plate 9 has a friction drive on to a wheel 11 of a gear train and is so arranged that when the disc 6 is turned to the left or right corresponding contacts, (not shown), are engaged and the disc 6 is returned by a spring, (not shown); and delayed by the gear train. The use of a disc instead of an operating lever avoids a conspicuous off position and thus avoids confusion when using the switch when the steering wheel is turned. In the middle of the disc 6 is a press button 7 carrrying a contact 15 which when depressed against the action of a spring 16, engages a contact 14, held in a rubber ring 12, to complete the horn circuit.
