Title: Telephone switches and monitoring circuit therefor
IPC: H04M3/08
Filed: 1964-11-18
Abstract: 1,068,630. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Nov. 18, 1964 [Nov. 26, 1963], No. 46908/64. Heading H4K. The performance of the selectors at a stepby-step exchange is monitored by equipment attached to the first selector which records each step, vertical and rotary, taken by the selectors in response to a negative pulse generated by the release of the relevant magnet. It is customary to provide protection networks 22, 24 and 23, 24 to dissipate the stored energy when the vertical and rotary magnets are disconnected. To effect the monitoring function, these networks are connected by way of capacitor 16 and diode 15 to the tip wire of the incoming line. The monitoring equipment, partly shown at 38, is associated with a first selector by a seizure control circuit 31 which opens the relevant gate 30 and identifies the selector by a signal on wire 28. Both the positive dial pulses and the negative stepping pulses from the magnets are present on the tip wire 6, as indicated in Fig. 4B. A detector 36 responds only to the former and repeats them over wire 37 to a register, while the latter are transmitted over a diode 32, capacitor 34 and wire 12 to a second register. The dial pulses are compared with the corresponding stepping pulses, and if they do not match a signal is sent to a control circuit. A signal is also sent if no stepping pulses resulting from rotary hunting are received. In either event a tape punch comes into operation, the first selector is identified, and the dial digits and stepping digits are recorded, thus enabling the defective selector to be located. An " all trunks busy " condition may be detected by the receipt of the maximum number of pulses arising from rotary stepping. A dial pulse analyzer may be incorporated to check that any trouble is not due merely to distortion of the incoming pulses. The operations of line finders may be monitored in a similar way to enable a calling line to be identified.

Title: An electric circuit arrangement for remote supervision of heating plants
IPC: G08B25/00
Filed: 1964-11-20
Abstract: 1,093,076. Supervising circuits. A. V. HILLBERG. Nov. 20, 1964 [Nov. 22, 1963], No. 47396/64. Heading G4H. A supervising circuit comprises a number of resistors 10-13 adapted to be connected into or disconnected from a closed electric circuit depending upon the state of equipment to be supervised and a contlrol unit adapted to give an alarm when the total resistance of the circuit rises or falls below predetermined levels. The resistors 10-13 are short-circuited by contacts 14-17 under certain conditions. At the central station the lines are normally connected to relay coil 22. The contact of this relay is normally balanced between contacts 27 by the attraction of coil 23. An adjustable resistor 18 facilitates the balancing. If the current in coil 22 changes owing to a change of resistance in the circuit A the contact moves and lights a lamp 26. The operator at the central station then transfers contacts to apply an ohmmeter or bridge 28 to the circuit to measure the resistance. The resistors may all have different values so that the value of circuit resistance indicates which of the resistors 10- 13 has been cut-out or put into the circuit. Upper and lower threshold indications may be given by separate relays. In another form the threshold relays are replaced by Schmitt triggers, each comprising a pair of transistors. In outputs of the triggers are connected to enable a transistor multivibrator circuit which causes a lamp to flash when either predetermined level has been passed. The circuit may be used to indicate liquid level, the resistors being connected in turn in a series circuit as the level changes. An alarm is given if upper or lower limits are passed and the ohmmeter may be used at any time to measure the level. The current for the resistors 10-13 passes through a diode 59. Another chain of resistors 60, 61 is connected in parallel with the first through an oppositely poled diode 64. The resistance of this chain can be measured by the ohmmeter 28 in the same way as the first, upon reversing the polarity of the ohmmeter.

The tape (9, Fig. 4, not shown) may be wound on the main insulation (7) or on a carrier (8) or on an insulating sleeve which is then folded round the insulation; or the voltage control arrangement may be a separate unit with terminals.

Abstract: 1367919 Fuel elements KERNFORSCHUNG mbH GES FUER 15 Oct 1971 [17 Nov 1970] 47990/71 Addition to 1205350 Heading G6C A fuel element has a pressure-equalizing double-walled cartridge 11 located in a cavity 10 within the fuel element cladding 1, above a porous pellet 9 which separates the cavity 10 from the fuel 2. The cartridge 11 forms a doublewalled cup, the inner wall of which is open in the region of its lower end. A fission gas plenum 4 between the inner walls of the cup is closed at the top by a lid 13 penetrated by a sealed filling tube 16 and by a tube 14 containing a liquid metal plug 15 which melts at reactor operating temperatures. Within the double walls of the cartridge 11 is a vapour plenum 5 filled with water 7 and vapour 6 and sealed off from the fission gas plenum 4 by a sealing plug 8. The plug 8 consists of bismuth which is liquid at reactor operating temperatures. During reactor operation, pressure is transmitted from the cavity 10 through the tube 14, through the now liquid plug 15, into the fission gas plenum 4 and from here through the liquid sealing plug 8 and into the vapour plenum 5. As the fission gas pressure in plenum 4 rises, so the pressure in plenum 5 rises until the vapour 6 has reached the state of dry saturation. From now on, the pressure in plenums 4, 5 and thus also in cavity 10 remains constant with further increases in the quantity of fission gas, because the vapour starts to condense and the volume this makes available can accommodate the fission gas. Only after all the vapour has condensed does the pressure rise again. For safety resaons, several small cartridges may be arranged one behind the other instead of using a single large cartridge.

The most preferred starting material is soya bean oil and the preferred extraction solvent is acetone. The invention is described with reference to a flow diagram included with the Provisional Specification (not shown). The example describes the epoxidation of soya bean oil.
