Abstract: 1,176,358. Semi-conductor devices. CSFCOMPAGNIE GENERALE TELEGRAPHIE SANS FIL. 26 July, 1967 [10 Aug., 1966], No. 34410/67. Heading H1K. [Also in Division H4] A capacity matrix for use as a television pickup device comprises an array of light-sensitive metal-oxide-semi-conductor capacitors having their metal parts connected together in columns and their semi-conductor parts connected together in rows. The matrix may be formed in a single N-type Si wafer 3 having an oxide coating 2, contact to the semi-conductor parts of devices lying in each row being made by a diffused N+ strip 401, 402 &c. The metal electrodes of each device, e.g. 111, 112, may be joined by a strip 501. In an alternative arrangement a single device has two electrodes (41, 42), Fig. 7 (not shown), attached to the semiconductor body (3), one at each edge of the oxide coating (2). Fig. 3 (not shown), illustrates the preferred circuit using the matrix. A delay line (LR) receives pulses from a generator (GA), and delivers them in timed relationship to the metal electrodes of the devices lying in successive columns of the matrix. The semi-conductor electrodes of the devices in each row are connected to a load resistor (e.g. R 1 ), and thence to one input of a switch (c), which feeds the outputs from the various rows cyclically to an amplifier (A). The magnitude of the current pulse through each load resistor (e.g. R 1 ) resulting from the application of the voltage pulse to the metal electrode of one of the devices connected thereto (e.g. D 11 ) is influenced by the intensity of light falling on the device, and the amplifier (A) therefore receives a series of pulses related to the pattern of light falling on the matrix. An optical image forming means (1000), Fig. 14 (not shown), is arranged in front of the matrix (1001) to complete a television camera.

Title: Improvements in or relating to lighter-than-air aircraft
IPC: B64B1/58
Filed: 1927-12-19
Abstract: 309,969. Airship Guarantee Co., Ltd., Burney, C. D., and Bird, A. L. Dec. 19, 1927. Divided application. Aerostats.-An airship has compartmented or separate bags for lifting gas, and a fuel gas containing less than approximately 50 per cent of free hydrogen which is burnt in: the engines in conjunction with oil fuel so as to maintain the static equilibrium of the airship or to ensure any required variation of buoyancy as the fuel is consumed. The gas and oil may be used in different engines or in the same engine and in the latter case the gas and air after spark ignition serve to ignite the atomized oil fuel which may be thereby induced through a carburettor jet during tha suction stroke or forcibly injected into the cylinder at the end of the compression stroke or at the beginning of or during the firing stroke. The fuel gas under pressure may be used as in an injector to atomize the oil especially when kerosene or mixtures of kerosene and Diesel oil are used. The engines are started on gas and air only after which the gas is reduced and the oil added. The induction pipe may be electrically heated. Kerosene, paraffin or Diesel oil may be used as liquid fuel and the gas may be of a density varying from 50 per cent to 80 per cent of that of air and contain methane, ethylene and higher gaseous members of these series, or coal gas, producer or water gas may be used. A suitable gas for example is that produced by the Pintsch process. The gaseous fuel is carried in the lower parts of the hydrogen gas bags and separated therefrom by a flexible partition C or contained in separate bags beneath the hydrogen bags. In either case the fuel gas is subjected to the expansion pressure of the hydrogen, and blow off valves E with vertical trunks E<1> are provided on both bags. In general, only fuel gas is lost on expansion and on the operation of manoeuvring valves. Strengthening bands on the lower bags are adapted to engage an axial girder D should the hydrogen bag become accidentally deflated. The engines are arranged at a higher level than the fuel gas bags which are gravity fed from perforated pipes arranged at the upper sides of the bags. The engines may be arranged in the fins as described in Specification 259,264.

Title: Solenoid pilot operated valve
IPC: H01F7/16
Filed: 1967-07-28
Abstract: 1,138,017. Valves. ITT INDUSTRIES Inc. 28 July, 1967 [4 Aug., 1966], No. 34816/67. Heading F2V. In a pilot-operated valve, energization of coil 42 moves pilot armature 54 to the right to abut main armature 48, this movement being transmitted by pin 58 to pilot 30 to unseat the latter against spring 52 to connect pilot chamber 20 to outlet 14 via passage 26 in main valve 18. Fluid from inlet 12 that had previously passed into chamber 20 via passage 22 to urge the pilot and main valves to their closed positions is thus exhausted and inlet pressure acting on annular surface 18a opens the main valve against spring 50 and seats armature 48 against the end wall of housing 30. The armature 48 is then retained in this position by the flux generated by coil 42. De-energization of the latter allows the pilot valve to seat and the pressure build-up in chamber 20, together with spring 50, seats the main valve.

Filed: 1927-12-30
Abstract: 283,154. Telefonaktiebolaget L. M. Ericsson. Jan. 5, 1927, [Convention date]. Automatic exchange selectors.-In a selector in which the contacts to be operated are arranged in a vertical row, the group selecting movement of a shaft results in the clutching of a sleeve thereto, and the desired contacts are then operated upon rotation of the sleeve by means of helically arranged pins thereon. One form is identical with that shown in Figs. 1, 3 of Specification 293,153. In another form (Figs. 4, 7), the sleeves 15 are selectively coupled to the shaft 16 by the rotation of an auxiliary shaft 36 carrying staggered pins 38.

Title: Crosspoint network for a time division multiplex telecommunication system
IPC: G11C15/02
Filed: 1960-10-14
Abstract: 904,233. Electric selectors. STANDARD TELEPHONES & CABLES Ltd. Oct. 14, 1960 [Oct. 20, 1959], No. 35318/60. Class 40 (4). To reduce the cross-talk in a cross-point matrix the row and column conductors comprise microstrip lines. The arrangement is applied to a time division multiplex exchange in which the cross-points have symmetrical junction transistors as switching elements. As shown in Fig. 4, the microstrip lines are sandwich lines with earth conductors C facing inwardly and line conductors A facing outwards. Separate transistors T and T<SP>1</SP> connect the C and A conductors at each cross-point. The sandwiches are supported at their ends in a matrix frame. As shown in Fig. 5, the earth conductors C may be printed on opposite sides of a baseboard and be covered by a thin strip of dielectric on which the line conductors A are deposited. At each cross-point the conductors have off-shoots with which the transistors T, T<SP>1</SP> connect, the off-shoots on one side of the baseboard connecting with the other by means of pins passing through the board. As seen in Fig. 7, the earth conductors C may be sheets common to the line conductors A of each coordinate direction, the sheets being separated by a baseboard P and the line conductors A being disposed on dielectric layers B. The baseboard P may be a conductor or an insulator, in which latter ease the earth sheets are connected at their edges, and the single transistor has access to the far line conductor at each cross-point through an eperture in the assembly for passage of a transistor lead or by means of an insulated pin passing through the assembly. If the baseboard P is an insulator the line conductors A may be inside the assembly adjacent the baseboard and the earth sheets, facing outwardly, screen the matrix. In this event the baseboard sandwiches a central conducting sheet which acts as a screen between the two co-ordinate sets of line conductors. The assembly may be produced by successively printing conducting surfaces or strips and depositing dielectric layers on a baseboard in which event the arrangement of Fig. 8 is preferred with a central conductive baseboard C providing an earth conductor common to both co-ordinate sets of line conductors A. Residual cross-talk may be attenuated by building up the assembly on an apertured baseboard so that the final assembly has interstices between the overlapping co-ordinate sets of line conductors and iron wire may be wrapped round the microstrip lines or ferrite rods may be placed in the interstices. Specification 765,681 is referred to.

Filed: 1938-12-05
Abstract: 522,267. Electric follow-up control systems. BRAHAM, G. W. Dec. 5, 1938, No. 35338. [Class 40 (i)] [Also in Groups XXXV and XXXVII] A motor, Fig. 1, is supplied from a D.C. source through a contact assembly comprising flexible levers 9-12 carrying contacts 13. The contact assembly is continuously vibrated by means of an eccentric 5 so that A.C. is applied to the motor, and by means of a member 22, the levers 10, 11 carrying the intermediate contacts 13 may be displaced in either direction, and consequently the duration of applied potential in one direction may differ from that in the other direction to give forward or reverse operation of the motor. In a follow-up system, Fig. 4, the member 22 is displaced by a handle 36 and differential gear 40, 41, while the motor 16 transmits movement to the planet wheels of the differential through machines 43, 44, to.restore the member 22 to its mid-position when the receiver and transmitter are in positional agreement. Stops 54, 55 limit movement of the member 22 and when a stop is engaged the machines 43, 44 are de-energized to facilitate movement of the handle 36. The de-energization is effected by a relay 50 controlled by a contact 47 or 49 operated by a machine 56 coupled with the motor 16 and connected to a machine 37 operated by the handle. The contact 47 or 49 is engaged when the positional disagreement between the transmitter and receiver exceeds a predetermined amount. While the relay 50 is energized the member 22 is held at its limited position by a coil 52 or 53.
