Title: Improvements in or relating to arrangements for automatically and continuously measuring the noise factor of an electric device
IPC: G01R29/26
Filed: 1954-09-30
Abstract: 758,994. Noise voltage measurement. INGENIORSFIRMAN MAGNETIC AKTIEBOLAG. Sept. 30, 1954 [Nov. 25, 1953], No. 28257/54. Class 37. Apparatus for measuring the inherent noise level of an electric signal transmission device comprises a comparison source of standard noise voltage controlled by a pulse generator through a pulse selector suppressing alternate pulses of the output thereof to supply a train of noise pulses separated by double pulse width intervals to the device under test, whose output is connected to a mixing device together with the direct output of the pulse generator to produce a train of noise pulses separated by single pulse width intervals and representing alternately the input noise + the inherent noise of the device and the inherent noise only, which train is rectified in a quadratic detector and separated into two respective component unidirectional voltage pulse-trains with double pulse width intervals which energize separate coils of a quotient meter indicating the noise factor of the device, defined as A pulse generator 2 develops a train of voltage pulses (a+b) having equal pulse and space widths, which is divided in a pulse selector 3 into two trains of pulses (a) and (b) having space width three times the pulse width and relatively displaced by two pulse widths. Train (a) is amplified to modulate a standardized source of noise voltage 5 to feed correspondingly spaced noise pulses into amplifier 1, whose output, comprising pulses of (amplifier noise + input noise) separated by pulses of (amplifier noise only) of three times the width, is supplied to a mixer 6 together with the pulse train (a+ b) from generator 2 whereby there is produced a train of alternate pulses comprising (amplifier + input noise) and (amplifier noise), separated by spaces of width equal to that of the alternate pulses. This noise pulse train is rectified in quadratic detector 7 to a train of corresponding alternately spaced direct voltage pulses which is separated by amplifiers 8, 9 gated respectively by pulse trains (a) and (b) from pulse selector 3, into trains of direct voltage pulses spaced by three pulse widths and of amplitudes respectively proportional to (amplifier + input noise) and to (amplifier noise) which energize the coils of a quotient meter 10 indicating the noise factor of the amplifier.

Title: Improvements relating to railway block signalling
Inventor: ROBERTS CHARLES GEORGE
IPC: B61L23/24
Filed: 1959-08-19
Abstract: 954,295. Block signalling systems. TYER & CO. Ltd. July 29, 1960 [Aug. 19, 1959], No. 28314/59. Heading B7N. In a block instrument signalling system using tokens for controlling traffic over a single line route, means are provided for preventing the extraction of a token from the instrument at the departure end of the block when standing currents from an extraneous source are present on the control wires connecting the instruments at the departure and arrival ends of the block. Assume a train has to be passed from a departure point A to an arrival point B, the operator at point A operates switch PA and applies battery XA1 to the control lines joining the instruments at the ends of the block. Relay ZB1 picks up and operates relay BB and the instrument at B indicates " line blocked." The operator at B, operates switch PB if he can accept the train, whereby relay ZB1 releases and relay CB picks up to hold BB. Indicator 1A at point A now indicates no current and the operator at A releases PA. The operator at B releases switch PB, relay BB releases but CB remains energized and the instrument displays " Train coming from A." The operator at B again operates switch PB whereby via a front contact of relay CB and a back contact of relay BB battery XB2 is applied to line and picks up both relay ZA1 and relay ZA2 at point A. Pick up of these relays energizes relays BA and DA and on release of switch PB at B relay BA releases but relay DA is held by a latch circuit including a front contact of relay PA and a back contact of BA. An electromagnetic device ML at point A is now energized to release a token, after which the instrument at A registers "Train going to B." In the event of extraneous current appearing on the control lines either relay ZB1 picks up to prevent the setting up of the " Train coming from A," condition or ZA1 picks up to prevent the establishment of a latch circuit for relay DA.

Abstract: 321,037. Holt, W. Oct. 4, 1928. Vacuum tubes. - In filaments of thermionic valves &c. which are formed from flat ribbon or strip, microphonic noises due to the vibration of the filament are prevented by giving the ribbon. a partial twist, or a number of turns, so that it assumes a helical form. The strip is passed axially through the grid, attached at the lower end to the lead-in wire, twisted through two complete turns and its upper end welded to the usual spring arm or support. In place of a flat strip, a ribbon of any non-circular cross section having unequal axes may be employed.

Abstract: 861,901. Alkali chloride electrolysis cells. BADISCHE ANILIN- & SODA-FABRIK A.G. Aug. 20, 1959 [Aug. 26, 1958], No. 28457/59. Class 41. In an electrolytic cell containing a vertical cathode carrier plate adapted to receive liquid mercury as a fluid cathode flowing downwards on a vertical surface of said plate, a porous electrically non-conducting screening means is provided adjacent to the vertical surface of the plate for controlling the downward flow of mercury, said screening means having a plurality of openings sufficiently large to permit passage therethrough of an electrolytic solution but sufficiently small to hold flowing mercury against the plate. The screen may be a web, net or fabric of polyvinyl chloride, polyvinylidene chloride or copolymers of vinyl chloride and vinylidene chloride. As shown, the carrier plate 1 which may be of iron may be in the centre of the cell 5 with a screen 3 on each side to separate the mercury cathode 2 from the anode 4 of graphite lumps or granules. Mercury flowing down the centre plate collects in channel 9 and is pumped to the decomposer 7, where the amalgam formed in the cell is decomposed, and thence recirculated to the top of the cell. The cathode carrier plate may be wider at the bottom than the top to ensure adherence of the mercury. If, in order to reduce the flow of mercury, a screen is used having such small meshes that they may become clogged with mercury, a coarse-meshed screen is used in addition to ensure insulation of anode from cathode.

Abstract: 1,247,147. Data processing; data storage. INTERNATIONAL BUSINESS MACHINES CORP. 15 June, 1970 [30 June, 1969], No. 28783/70. Headings G4A and G4C. A data processing system includes an addressable data store and dataoutputregistertherefor, means for automatically resetting the data output register, each store read out cycle and means for selectively inhibiting the resetting means. A word from a read-only control store is placed in a register having a first portion feeding a utilizing system and a second portion containing an address, a GO bit and an OR bit. The register can also be fed from the utilizing system or a keyboard. The store is addressed by the address in the register or from the utilizing system or from a keyboard. The store is cycled to read out a word in response to a start key or a read signal from the utilizing system or if the GO bit in the register is 1. Whenever the store is cycled the register is reset in preparation to receive the word read out, and can also be reset by a reset key, but each of these reset operations is inhibited with respect to the first portion of the register if a control latch is set. The sequence of operations in each store cycle includes, in order: (a) resetting of the register, partially inhibited or not, (b) entry of the read-out word into the register, (c) resetting of the control latch, (d) setting of the control latch if the OR bit in the register is 1. The register ORs its input with its present contents so that the OR bit being 1 causes successive entries to be ORed together. The store could alternatively be a writable control store or any other form of store.
