Title: Improvements in or relating to pull-cord operated devices, particularly electric switches
IPC: H01H17/26
Filed: 1949-12-22
Abstract: 665,978. Actuation of switches. KING, D. M. Nov. 8, 1950. [Dec. 22, 1949] No. 32834/49. Class 38 (v). [Also in Group XXIII] In switches and other devices mounted in an elevated position and having a rocker arm operated one way by pulling one cord and the other way by pulling another cord, the cords 18, 19 are attached respectively to two members 11, 10 forming part of a handle and slidable relatively to each other but urged into the position shown by a spring 12, relative movement from this position being prevented at will by depressing a catch 15. In the position shown the cord 18 extends up taut to the rocker but the cord 19 is slack. To move the switch into its other position, the catch 15 is pressed in and the handle pulled causing the cord 18 to operate the rocker and the slack in the cord 19 to be taken up. To move the switch back again, the catch 15 is released and the handle moved still further downwards, the cord 19 effecting the return movement of the rocker while the plunger 11 slides up the tube 10 straining the spring 12. On releasing the handle, the spring 12 pulls up the tube 10 and the parts resume their original positions.

Title: A plate-type nuclear fuel element
Inventor: LORIN CHRISTIAN
IPC: G21C19/10
Filed: 1967-07-18
Abstract: 1,137,597. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 18 July, 1967 [26 July, 1966], No. 32891/67. Heading G6C. A plate - type fuel element comprises a series of fuel plates 24 held by two sides 14, 15 of a support which are hinged on pivots 16, 17 perpendicular to the fuel plates so that they can be swung clear of the plates. The pivots 16, 17 are rigidly connected to two bars 18 (only one shown) associated with two crosspieces 20, 21 formed with regularly spaced grooves in which the fuel plates 24 fit. The fuel plates 24 also fit in grooves in the sides 14, 15. The fuel element is suspended inside a case 7 by means of flanges 28, 29 at the upper ends of the sides 14, 15 which fit over the upper ends of the sides 12, 13 of the case. The fuel plates 24 are made from a suitable thickness of a fuel material, such as UO 2 , and surrounded by a metal cladding, generally of Al or Al alloy. A rod 6 by means of which the fuel element is handled is rigidly connected to the flanges 28, 29 by means of a collar 30. Lateral arms 32 are welded to the collar 30 at one end and to a tubular sleeve 33 at the other. A rod 34 mounted inside and secured to the sleeve 33 extends upwards so that the element can be grasped. A hollow rod 35 slides along the rod 34 and includes a slanting projection 36 which abuts the ends 37, 38 of two levers 39, 40 hinged on pivots 41, 42 borne by the supporting arms 32. Lateral pins 43, 44 on the lower ends of the levers 39, 40 engage passages 45, 46 passing through the sides 14, 15 of the support and also the sides 12, 13 of the case 7. In order to release the support from the ease 7, the rod 35 is caused to slide slightly downwards along the rod 34, comprising a spring 47 between the sleeve 33 and the lower end of the rod 35. The projection 36 turns the levers 39, 40 on their pivots 41, 42 so that the pins 43, 44 are drawn inwards. The fuel element can then be raised by means of the rod 34, whereupon the levers 39, 40 are returned to their original position by the return of the rod 35 and by the action of a spring 50 bearing on two shoulders 51, 52 on the levers. The fuel element is dismantled by removing the collar 30 and rotating the sides 14, 15 of the support about their pivots 16, 17. The case 7 comprises a spigot 8 terminating at its lower end in a tubular extension 8a fitting into a core support grid of, for example, a swimming pool reactor. Water flows up through a bore 8b in the spigot 8 to cool the fuel plates 24.

Title: Method of producing electric wiring arrangement
IPC: H05K3/10
Filed: 1971-07-14
Abstract: 1400394 Printed circuits; capacitors LUCAS INDUSTRIES Ltd 5 July 1972 [14 July 1971] 32931/71 Headings H1M and H1R Printed circuit cross-overs and capacitors are made by forming channels in the substrate, filling the channels with conductive material, applying a layer of insulating material to the conductive material and adjacent portions of the base and applying a pattern of conductive material to the substrate and the insulating material so as to complete the printed circuit, one conductor being conductively connected to the material in the channels and another conductor extending over the insulating material. A vitreous enamelled metal substrate 10, Fig. 2, has a layer of copper 14 sputtered on and thickened by electroplating. Apertures are etched in the copper where the channels are to be and the channels 11 are formed by sputter etching the copper layer being thick enough for at least some to survive the sputter etching. The whole surface is then covered by sputtering with a 200 A.U. layer 15 of nickel-chrome alloy and a 9000 A.U. layer 16 of nickel. The copper layer 14 is then etched with ferric chloride or ammonium persulphate to leave only the nickel-chrome and nickel layers in the channel. A silicon dioxide layer 19, Fig. 6, is then sputtered over the filled channel using a copper masking technique similar to that used for the channel. Finally, a nickel-chrome layer 20 and a 2000-3000 A.U. gold layer 21 are sputtered overall and the circuit defined by etching. The gold layer is etched from regions which are to act as resistors. In a modified method, Figs. 10-17 (not shown) the copper masks for sputter-etching the channels and sputtering on the conductors in the channel and the insulating layer are made by sputtering on to the substrate a copper layer applying a thin resist where the operation is to take place and building up the copper layer electrolytically so that when the resist is removed the mask has an overhang which gently tapers the edges of the sputtered regions.

Title: Improvements relating to Charging of Storage Batteries
Inventor: COOK FREDERICK JOHN
IPC: H02J7/00
Filed: 1967-07-18
Abstract: 1,197,086. Overcharge protection for batteries. CATYLATORS Ltd. 13 May, 1968 [18 July, 1967], No. 33033/67. Heading H2H. A battery charging circuit comprises a temperature sensitive bridge having two fixed ratio arms, a third arm having a first thermistor T1 and an arm including a second thermistor T2 and a resistor R3, the thermistors being influenced by the temperature of a battery, one diagonal of the bridge circuit being connected to a source of constant D.C. current and the other diagonal to a means through which the battery is charged. Thermistor T1 has a higher resistance than that of thermistor T2 at the same temperature, and T1 may be exposed to hydrogen gas evolved from the battery. The thermistors will be equally effected by ambient temperature hence providing compensation for this effect. After connection of a supply and a battery to the circuit thermistor T1 will heat up more than thermistor T2 hence its resistance will fall more than that of the latter, thus the bridge circuit passes to an out-of-balance condition giving an output of the polarity indicated hence charging the battery. Hydrogen evolved from the battery on the gassing will cool the thermistor T1 returning the bridge towards a condition of balance which reduces the charging current. In low temperature ambient conditions the resistances of thermistors T1, T2 will be too high hence Zener diodes Z1 Z2 provide a bypass so the output voltage at terminals 2 temporarily reverses in sign until the resistance of thermistor T1 falls. If the battery temperature should become sufficiently high the output from the bridge will be zero. Terminals 2 are connected to a device controlling charging current.

Abstract: 811,289. Electric selective signalling systems. CONSOLIDATED ELECTRODYNAMICS CORPORATION. Oct. 24,1957, No. 33172/57. Class 40 (1). A digital-to-analogue converter comprises a plurality of series circuits, Fig. 1, each circuit including a resistor 26 and a Zener diode 28 connected in series across a voltage source, a plurality of resistors 30 respectively connecting the series junction 24 between the resistor and diode of each of the series circuits to a common output terminal, a plurality of switching means (transistors 18) connected in shut across each of the diodes and input means (cathode followers 12) responsive to received binary digital information (from a store 10) for selectively setting each of the switching means to one of two impedance conditions depending upon the binary digits received, whereby the respective switching means provide a high or low shunting impedance across the respective diodes. Each transistor switch can be in a low impedance state, when the potential of point 24 is substantially Ov., or in a high impedance state when the potential of the point 24 is at a level determined by the break-down voltage (i.e. the Zener voltage) of the Zener diode 28, and this potential is maintained constant, irrespective of the current drawn through resistor 30, by the voltage stabilizing property of the Zener diode. Thus by suitable weighting the resistors 30 a voltage can be obtained which is an analogue of the digital input.

Title: Improvements in or relating to wire gauging apparatus
Inventor: HARRIS PETER MICHAEL
IPC: G01B11/08
Filed: 1954-11-18
Abstract: 761,739. Photo-electric gauges. KOLSTERBRANDES, Ltd. Nov. 18, 1954, No. 33388/54. Class 40 (3). In a comparison method of testing the diameter of a wire the illumination of a photo-cell is reduced by inserting the wire under test between it and a light source while the illumination of another is obstructed by a photographic wedge. As shown, the wire CW under test passes continuously between light source LS and photo-cell V6 while an optical wedge of known type is situated in the light path to another cell V5. The outputs of the two cells are compared and a meter indicates deviation of the diameter of the wire from a valve corresponding to the wedge setting. The wedge setting is determined by replacing the test wire by a standard wire and adjusting the wedge until the meter reading is zero. The meter is of the centre zero type so that deviations of the test wire each side of the correct value may be indicated. The apparatus may be used for indicating the thickness of coating on wires. Circuits.-Photo-cells V5, V6 are connected in series with each other and with a stabilized D.C. supply. The junction of the cells is connected to the grid of an electrometer pentode V4 the anode, cathode and screen potential of which are derived from a potential divider R6, R7, R8, R9. A resistor R10 constitutes the anode load of the valve. The anode of the electrometer is connected to one control grid of a double triode V3; the screen to the other grid. The cathodes of the double triode are coupled and a milliammeter M1 is connected between the anodes. The unit is so arranged that with equal illumination of the two cells the electrometer current is such that anode and screen potentials are the same. Hence the two grids of the double triode are at the same potential and the ammeter indicates zero. The potentials at the anodes of the double triode may be used to control the manufacture of the wire.
