Abstract: 982,406. Ionization manometers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 12, 1961 [July 15, 1960], No. 25237/61. Heading H1D. An ionization manometer comprises an ioncollector wire 11 stretched within a helical wire anode 7 on the outer side of which a filament cathode 5 is arranged, the diameter of the collector wire 11 being less than 10 microns. The circuit provides in operation an anodecathode voltage of not more than one fifth the anode-collector voltage. The anode and collector voltages are preferably chosen so that the collector current tends to become independent of the anode-collector voltage, which is preferably less than 500V, the collector being earthed, and the anode-cathode voltage being stabilized. As shown, the V-shaped filament 5 is stretched between three leads 4 and the end turns of the helical wire anode are progressively reduced to counteract the escape of ions. The tungsten wire collector has a diameter of 4Á and is stretched by a spring 10, glass tubes 16 shielding the connections to leads 9. The envelope has a conductive tin-oxide coating 15 which may be directly connected to the cathode. Electrode dimensions are given. Anode and collector voltages of + 55V and - 250V respectively result in low X-ray emission and enable pressures down to about 10<SP>-13</SP> mm. to be measured.

Title: Improvements in or relating to electric negative resistances
IPC: H01C7/10
Filed: 1930-08-27
Abstract: 368,770. Generating and amplifying oscillations. HABANN, E., 44, Stargarderstrasse, Berlin. Aug. 27, 1930, No. 25594. Convention date, April 3. Addition to 367,790. [Class 40 (v).] A powdered resistance having a negativeresistance characteristic as claimed in the parent Specification and suitable for amplifying or generating electric oscillations, has incorporated with it a catalytic substance which is capable of absorbing the medium which the contact substance adsorbs, or it may be placed in a medium which is strongly adsorbed by the contact, the medium being preferably at superatmospheric pressure, or both these measures may be taken together. An oxide melt consisting of zinc oxide and 3 per cent by weight of copper oxide associated with an iron wire or a sulphide mixture associated with a molybdenum wire may be placed in an oxygen atmosphere at superatmospheric pressure. Suitable catalysts for use with oxygen are charcoal, cuprous oxide, osmium, vanadium, and the oxides of vanadium, osmium, manganese, cobalt, nickel, tungsten, and chromium. Platinum, preferably in the form of platinum black, may be employed either as a coating on one or both of the electrodes, or incorporated in the powdered contact substance. To prevent the formation of conductive bridges by coherer action, neutral nonconducting powder as referred to in the parent Specification (e.g. finely divided aluminium or antimony oxide) may be mixed with the platinum black, the mixture then being added to the powdered contact substance. Preferably, however, a nonconducting contact substance such as cerium or thorium oxide is employed. As described in the parent Specification, powdered metal may be added to the negative resistance powder. Powdered alloy of a metal having a good negative resistance with a metal that regenerates well may be employed, or a powder of the firstmentioned metal provided with a coating of the second-mentioned metal. The degree of compression is adjusted to the optimum value for regeneration, the thickness of the layer of powder, usually below one millimetre, being chosen to give the best development of the negative characteristic. The electrodes should be of a refractory metal. The resistance of the powder is broken down at such a small current intensity that it just remains conducting. Specification 368,270 also is referred to. Reference has been directed by the Comptroller to Specification 103,046, [Class 37, Electricity, Measuring &c.].

Title: Device for the control of the measure of transmission in telephone systems, amplifying systems or the like
IPC: H04B3/20
Filed: 1928-09-06
Abstract: 322,517. Hahn, W., and Warncke, H. Sept. 6, 1928. Repeating and amplifying systems.-The gain of an amplifier is automatically adjusted by a magnetically controlled thermionic valve, the current in the control-winding of the valve being dependent on the signal current in-coming to the amplifier. The invention is described in connection with echo-suppressing arrangements for telephonic repeaters. In the two-way repeater shown in Fig. 1, the path for transmission east comprises windings of transformers U1, U1<1> in series with a battery Q1 and magnetically controlled valve M1, normally forming a low resistance circuit. From the secondary of transformer U1<1>, the speech currents pass through one or more amplifiers VI and are fed into line L2 by the transformer N1. The path in the reverse direction is similar, and rectifiers G1, G2 for supplying current to the controlling windings W1, W2 of the valves M1, M2 are fed with speech current by balancing transformers A1, A2, networks B1, B2 being inserted as shown to balance the transformers N2, N1. During transmission east, the secondary of transformer A1 is unaffected, but induced current in the secondary of A2 is rectified by G2 and the resulting current in winding W2 increases the resistance of the valve M2 and blocks the return path over transformer U2<1>. In the modification shown in Fig. 2, the valve M1, controlled by the winding W1, is provided with a control grid S, and also functions as an amplifying valve. In a modification of the arrangement shown in Fig. 2, the magnetically controlled amplifying valves V1, V2, Fig. 3, in each path are controlled by windings W1, W2 in the output of rectifier G1, and additional windings R1, R2 supplied with adjustable current from the battery P are used to control the normal condition of the valves. The current in windings R1, R2 may be adjusted so that, when speech currents are not passing, the gain of valves V1, V2 is small. Speech currents incoming from east over D2 pass through V2 and a rectified portion thereof is fed over windings W1, W2 in such a direction as to increase the gain of V2 and decrease that of V1. In a further modification, the rectifier supplying current to the windings W1, W2 may be arranged on the input side of V1 and so that speech currents incoming from west increase the gain of VI and decrease that of V2. In order to avoid effects due to variation of the energy level of incoming currents, the windings W1, W2 may be fed with rectified current from a valve operating at its saturation point.

Title: Data processing apparatus
IPC: G06F11/20
Filed: 1969-05-20
Abstract: 1,263,969. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 20 May, 1969 [3 Sept., 1968], No. 25657/69. Heading G4A. In data processing apparatus, selectors normally connect a plurality of logic units with an input, an output, and each other, failure of one of the logic units causing the selectors to bypass it and utilize a spare logic unit. Fig. 1 shows a byte ALU (arithmetic and logical unit) which receives input transformed from parity-checked form to 2-wire form, and utilizes the latter form for checking its operations, its output being transformed back to parity-checked form. The possible operations are addition, subtraction, shifting and logical operations e.g. AND, OR, EQUALS, EXCL-OR. P and Q are input registers, a register T generates functions of two variables, a register G performs pass through, complement, 2-bit endaround right shift or all zero output, a register S performs EXCL-OR, a register C contains carry circuitry, a one-bit register YC is a carry buffer and is used for communication with other byte ALUS, and a function register F contains a function code. To permit operation despite faults, a spare function register F<SP>1</SP> and a status register ST are provided, register YC has triplemodular-redundancy, and one (or more) spare bit positions are provided in registers P, Q, T, G, C, S. The ALU is constructed in part from a plurality of logic planes, each consisting of a corresponding bit position from each of registers P, Q, T, G, C, S with the interconnections of Fig. 1 plus an input to C from the next lower order plane (if any) and an output connected to this input in the next higher order plane (if any). However, if a (non-spare) plane is faulty, the status register is set to control gates so that the bit inputs to P and Q at the faulty plane and higher order planes are all displaced one plane to high order so that the faulty plane is not used and the first of the spare planes is brought into use (the spare planes being adjacent the high order end of the sequence of non-spare planes). Similarly the output connections are displaced, and the faulty plane is by-passed in the connections between planes. Similarly if more than one non-spare plane is faulty (assuming a sufficient number of spare planes). The status register also has a bit position to gate one of the function registers F, F<SP>1</SP> to the logic planes according to which if any of the function registers is faulty, the gates for this being provided once for each plane separately. Each plane could alternatively handle a plurality of bit positions.
