Title: Improvements in automatic telephone systems
IPC: H04Q3/00
Filed: 1937-11-11
Abstract: 505,506. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 11, 1937, No. 30998. Convention date, Nov. 14, 1936. [Class 40 (iv)] A switching arrangement comprises a number of pairs of electronic or other discharge paths U1, U2 connected in multiple to subscribers' lines AL and giving access to links FL which are also multipled to the discharge paths. According to the invention, line AL and link FL are connected over resistances rl, r2, r5, r6 to batteries E1, E2 of different voltages, the difference E1-E2 being less than the striking voltage of the paths. When subscriber A1 calls, the voltage dropped over resistances r1, r2 causes the paths to strike and busies the line, the link being busied by the voltage drop over r5, r6. Resistances shunted by condensers similar to those shown may be connected between points 5, 6 and subscribers' line to adjust the line resistance. In order to ensure that only a corresponding pair of paths shall strike, the striking voltages for different pairs may be graded, or the striking of one path U1 may bring about the striking of the other path U2. Numerical selection of a subscriber's line may be effected by application of marking potential over ML to grid electrodes with or without a change of voltage applied to the link. The line may be rung in the ordinary way or by causing the discharge tubes to oscillate.

IPC: G02B6/12
Filed: 1969-06-19
Abstract: 1,269,702. Superconductor devices. TEXAS INSTRUMENTS Inc. 19 June, 1969 [15 July, 1968], No. 31036/69. Heading H1K. Energy barriers capable of E.M. radiation emission defined between pairs of superconductors (Josephson junction) are interconnected by means of dielectric waveguides. As shown, Fig. 6a, an A.C. Josephson junction is produced by depositing a control conductor 22 on an insulating substrate (not shown), covering with an insulating layer 20, depositing a first superconductor gate strip 18, depositing a second insulating layer 24 of a photoresist which is exposed and developed to form a window 26, forming a tunnelling barrier layer 28 by glow discharge oxidation of the exposed portion of the superconductor, and depositing a second superconductor gate strip 30. When suitably biased the resulting Josephson junction emits radiation (far IR) which is coupled to other junctions on the substrate by means of a waveguide formed by suitably shaping the photoresist layer 24. When the radiation from a first junction is coupled to a second junction their frequencies are superimposed causing a frequency modulation which is manifested as a voltage modulation across the second junction so that high-speed computer elements may be constructed. The control conductor 22 enables a magnetic field to be applied to the junction to control the radiation frequency. The substrate may be of soda lime glass or a plastics material and the superconductor may be lead or another Type I or a Type II metal or a compound. Mention is made of lead nitride barriers produced by glow discharge. The Josephson junction may also comprise a superconducting bridge, a pressure contact or a granular film. A flexible substrate covered with photoresist may be connected mechanically or bonded chemically (e.g. using stearic acid) to the photoresist waveguide on the substrate to form an interconnection between arrays.

IPC: H04L25/14
Filed: 1966-07-12
Abstract: 1,190,367. Digital transmission systems. PLESSEY CO. Ltd. 7 July 1967 [12 July, 1966], No. 31191/66. Heading H4P. A telegraph transmitter includes means for dividing the input signals, having a given bitrate, into two signals each of which is at half the bit-rate and is transmitted on a separate channel. The receiver combines the channels to reproduce the original bit-rate signal. In the embodiment described single or double current bit-rate signals pass via a matching unit and control two multivibrators such that one oscillates during a Mark bit and the other during a Space bit. The multivibrator outputs are detected and control a bi-stable unit which provides complementary signals on two channels. These signals are differentiated to provide, respectively, a pulse at each Mark-Space transition and a pulse at each Space-Mark transition. The pulses pass to respective units which produce signals at half the bit-rate. These control two silicon controlled rectifiers whose outputs are transmitted. Each channel at the receiver is connected to a respective channel comprising in series a matching unit, an oscillator, a detector, a bi-stable unit, and a monostable unit. The outputs of the latter are combined in a driver stage which passes bit rate signals to a silicon controlled rectifier, giving the reconstructed signal. One of the monostable units is manually adjusted prior to data transmission to compensate for any difference in propagation time in the two transmission channels. To do this a 1: 1 Mark- Space ratio signal is transmitted and the monostable adjusted until a meter fed by the receiver output shows a desired reading.

Title: Purification of gases containing sulphur oxide products
IPC: B01D53/50
Filed: 1967-07-07
Abstract: 1,203,451. Purifying combustion gases. WEIR PUMPS Ltd. 7 July, 1967 [20 July, 1966; 8 Feb., 1967], No. 31385/67. Heading B1R. [Also in Division C1] In a process for purifying gases containing sulphur oxides, e.g. combustion gases, the gases are treated at a flow rate and temperature by injecting thereinto an amount of an alkaline substance such that the sulphur oxides are converted into a sulphite and/or bi-sulphite, the thus treated gases being then scrubbed to remove the sulphite and/or bisulphite without decomposition thereof. Ammonia is the preferred alkaline substance and the temperature of the gases when the alkaline substance is injected is between 10‹ and 180‹C., preferably 50‹ to 150‹C. The scrubbing agent may be water at a temperature of the order of 50‹C. The amount of alkaline substance added may be close to that stoichiometrically necessary to produce a sulphite or that necessary to produce a bi-sulphite. As shown in Figure 1 a gas at 150‹C is sprayed with an alkaline substance from nozzles 2 in a conduit 1 and is afterwards scrubbed in a vessel 4 by passage through a thin layer of liquid maintained on a perforated plate 7. Scrubbing liquid is supplied at 11 and withdrawn via overflow 14 and the sump 6. In a modified apparatus for carrying out the process a chamber may be interposed between the point of introduction of the alkaline substance and the scrubbing vessel. This intermediate chamber may contain heat-exchange elements and condensate collecting in the chamber may be reintroduced into the gas entering through conduit 1. Liquid drawn off from the layer of liquid on plate 7 may be mixed with such condensate.

Abstract: 1,011,401. Electric digital calculators. W. & T. AVERY Ltd. Sept. 5, 1962 [Sept. 8, 1961], No. 32257/61. Heading G4A. An automatic apparatus for taring a container prior to feeding into it the material to be weighed comprises an adding circuit to which are fed signals indicative of the tare weight of the container. To this circuit are fed further signals from counting circuits until their sum shows as zero, whereupon the counting circuits are stopped. The embodiment described uses a two-stage decimal arrangement A 1 , A 10 , and a two-stage decimal counter C 1 , C 10 . In use, counter C 1 , C 10  is set to zero and the container placed in the weighing machine which is coupled to a coded scale which co-operates with photoelectric means to provide binary signals indicative of the container's weight. These signals are fed to A 1 , A 10  at terminals B 1 , B 10 . A clock pulse train is now caused to pass via gate G to counter C 1 , C 10  which feeds a binary count to A 1 , A 10 . When the sum of the container's weight and the count on C 1 , C 10  reaches 100 both A 1  and A 10  will indicate zero on all terminals and the " carry" pulse causes gate G to be disabled. The count now stored in C 1 , C 10  is thus 100-(container weight). When material is added to the container the value indicated on A 1 , A 10  will be the true weight of the material.
