Title: Control and holding circuit for a relay matrix
IPC: H04Q3/00
Filed: 1974-06-26
Abstract: 1474785 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 26 June 1974 [27 June 1973] 28452/74 Heading H4K A switching network of relay switching matrices comprises electronic control and holding circuits common to a plurality of relays (e.g. a row or column) of a matrix. As described the circuits are fabricated as integrated circuits and eliminate a holding contact and isolating diode for each relay. Also since the holding current does not pass through the contacts of the relays it can be used for a path search without operating any relays and, once a holding path has been selected and set up, the current level on that path can be increased to operate the corresponding relays and cut through the speech path. The switching network comprises 2 Î 2 matrices of reed relay switches and the Figure shows two switching stages A and B. To select a path a marking potential UM is applied to the hold wire l of the B stage and marking potentials Um are applied at m to one control and holding circuit (shown as a rectangle) in each stage to test a path via that stage. Various transistor embodiments for this circuit are described incorporating thyristors which may be light sensitive and controlled by light emitting diodes or Hook flip-flops. The circuit in the B stage if associated with a free relay propagates the marking UM via terminal C and a link L to the stage A. Depending on the speed of marking or whether the marking potential is supplied by a current limited source the complete path may be selected before or without operation of any relay or the relays selected may be operated stage by stage. The paths are tested in random fashion until a free path is found any incomplete path being released.

IPC: G21B1/00
Filed: 1955-10-06
Abstract: 851,355. Nuclear reactors. METROPOLITAN VICKERS ELECTRICAL CO. Ltd. Dec. 19, 1956 [Oct. 6, 1955], No. 28518/55. Class 39(4). In a fusion reactor deuterium and tritium ions from an annular source IS are accelerated radially inwards by the field between poles P of an electromagnet Y, to produce fusion reactions with emission of heat and some neutrons. These neutrons react with Li<SP>6</SP> in the cylindrical walls W of the reactor to produce more tritium. The deuterium and tritium in the reaction space moderate the neutrons, increasing the Li (n, t) reaction. Natural or enriched lithium is used and may be in the form of lithium deuteride or lithium tritide. Liquid or gas coolant passes through a heat exchanger HE and steam from HE drives a turbine PM. In modifications the ions are accelerated in an electric field or by radio-frequency electromagnetic waves.

Title: Separation of glycerine and other lower polyhydric alcohols from the hydrogenolysis products of saccharides
IPC: C07C29/80
Filed: 1963-07-19
Abstract: 992,165. Separation of glycerine from the products of the hydrogenolysis of saccharides. ATLAS CHEMICAL INDUSTRIES Inc. July 19, 1963 [July 25, 1962], No. 28633/63. Heading BIB. Glycerine is separated from the products of the hydrogenolysis of saccharides by a threestage distillation process wherein the components of the hydrogenolysis product which boil at a lower temperature than glycerine are distilled over in a "Splitter" column, the bottoms fraction from the "Splitter" is fractionated in a "Tetritol Column" to obtain a heads fraction which contains substantially all the glycerine, and this fraction is then re-fractionated a "First Glycerine Column" and a "Second Glycerine Column" in order to obtain pure glycerine. The flow diagram relates to the treatment of a nickel-catalysed hydrogenolysis product of invert sugar which contains glycerine together with water, ethylene glycol, propylene glycol, 1,2- and 2,3-butanediol, 1,2,3- and 1,2,4-butanetriol, tetritols, and hexitols. The product is diluted with water, filtered, and then passed through an anion and a cation exchange medium to remove ionizable impurities. The product is next freed from water in a "Water Column", operated at a base-temperature of 230 ‹C. and a pressure slightly above atmospheric. The dehydrated product passes to the "Splitter". The top of this column and of the following columns are maintained at an absolute pressure of 100 mm. Hg. and a basetemperature of 230 ‹C., and sufficient open steam is fed into the bottom section of each column to effect distillation. The overhead fraction from the "Tetritol Column" is heated at 145 ‹C. with 0À1% of sulphuric acid for 4 hours at an absolute pressure of 10 mm. Hg., in order to convert polyols having boiling points near glycerine into compounds which can be more readily separated from glycerine. The acidified material is diluted with water to obtain a glycerine concentration of about 90%, and the diluted fraction is neutralized by passing it through an anion exchange medium. The heads fraction from the splitter may be fractionated at atmospheric pressure in order to separate a fraction containing propylene glycol and the butanediols from a fraction containing ethylene glycol. Specification 354,196 is referred to.

Abstract: 873,826. Photographic printing. AGFA A. G. Sept. 17, 1957 [Sept. 29, 1956], No. 29285/57. Class 40(3) In photographic copying apparatus in which printing material is exposed to printing light transmitted via the negative being copied, the gradation of the printing material is controlled by an auxiliary light source which illuminates the material directly during the printing process with an amount of light which is a function of the density variations of the photographic negative. Light from a lamp 3, Fig. 1, passes via a condenser 4, a photographic negative in holder 5 and an abjective lens 6 to a print holder 7. A semitransparent mirror 12 directs part of the light via a lens 18 and scanning disc 21 to a transluscent screen 17 and the image on the screen is brought to a focus on the cathode of a photomultiplier 19 by lens 19a. In addition, light from an auxiliary lamp 13 is directed by the mirror 12 to the prinr holder 7. The voltage generated by the photot multiplier is amplified by a logarithmic amplifie- 27, Fig. 2. The amplifier output, which is a function of the density range of the negative, is applied to a meter 32 having a pointer 36 which is deflected to engage one of the contacts 37, 38 in the supply circuit to a motor 35. The motor rotates the meter until its pointer takes up a position between the two contacts, and also rotates a potentiometer arm 43 to a position which is a function of the density variations. The potentiometer 44 forms part of a circuit supplying the auxiliary lamp 13. The D.C. component of the photomultiplier output is applied to a control circuit 48 which - determines the duration of the exposure of the printing material. During exposure the print is subjected to light via the negative and additional light from the source 13, after a predetermined time, controlled by a timer 47. A relay 46 opens the circuit to the auxiliary light source and after a further period determined by the exposure timing circuit a relay 49 opens the circuit to the printing lamp 3. In a further arrangement, Fig. 3 (not shown) the auxiliary lamp is controlled by a thyratron valve circuit.
