Title: Explosion turbine
IPC: F02C5/12
Filed: 1952-12-19
Abstract: 759,846. Gas turbine plant. SCHILLING ESTATE CO. Dec. 19, 1952 [Dec. 24, 1951], No. 32275/52. Class 110(3) A gas turbine plant adapted for use as a generator of hot combustion gases under pressure comprising a number of explosion chambers disposed around the lower half of the turbine casing with their axes parallel to the axis of the turbine rotor shaft has the chambers united together so as to form blocks, preferably in groups of two. The invention is described with reference to a gas turbine plant of the type described and claimed in Specifications 759,840 and 759,841. The turbine rotor 1 having two rows of blades 4, 5 is enclosed in a housing 6, combustion gases are fed to the blades 4, 5 by four explosion combustion chambers 7, 8, 9, 10, in the manner described in the above mentioned Specifications through discharge valves 18, 27, 40. The chambers 7, 8 are formed into one block and the chambers 9, 10 into another. The plane of symmetry of each block makes an angle of approximately 45 degrees to the horizontal plane. The turbine housing 6 is split on the horizontal plane but the end cover plates 13, bearings 14 and labyrinth packings are made in one piece. The casing is held together by bolts 42 enclosed in a tube 41 which are, after tightening hard soldered. The gases from the explosion chambers pass through passages 21 to the nozzles 18, 27. The seats of these valves are arranged in a plane perpendicular to the radius of the turbine housing 6. The air charging valves 36 each contain a fuel injection valve 37. The valves 18, 27, 40 of each block of chambers are actuated by control shafts 46, Fig. 4 which lie in the plane of symmetry of each block. A bush 47 carying an operating cam 51 is mounted on each shaft 46 and its angular position can be adjusted relative thereto by means of a. bolt 52 having square end 50 acting through an arm 48, pins 49 and helical slots 50a, 50b. The cam 51 actuates the pilot valve of a servomotor used to open the valves. The control shafts 46 are driven from a, main control shaft which extends transversly of the engine below the blocks 7, 8, and 9, 10 through shafts and bevel gearing. The main control shaft is driven by an electric motor and is provided with cams for actuating the fuel pumps and the pilot valves of the servomotors controlling the air inlet valves 36. Ignition devices are driven from the main control shaft through gearing. Casings around the main control shaft, the shafts 46 and shafts controlling the air inlet valves form with the explosion chamber blocks 7, 8 and 9, 10 a rigid assembly so that an separate frame is unnecessary. The whole plant is supported from the combustion chambers 7 and 9. A form of gas outlet valve which makes it possible to assemble the parts outside the turbine casing as a unit is also described. Specification 759,845 also is referred to.

Title: Antihistamine salts
Filed: 1952-12-19
Abstract: Antihistaminic salts are prepared by reacting gentisic acid with an N-aminoalkylphenothiazine substituted in the amino group. A solvent such as alcohol is used, and double decomposition may be effected between the hydrochloride of the N-aminoalkyl-phenothiazine and the gentisic acid sodium salt.  An example describes the preparation of the gentisic salt of N-diethylaminoethyl-phenothiazine.

Title: An Arrangement for the Production of a Programmed Tape by the Optical Scanning of a Graphically Represented Original
IPC: D03C3/20
Filed: 1967-07-13
Abstract: 1,190,093. Programmed electric control. FRANZ MORAT G.m.b.H. July 13, 1967 [July 21, 1966; Dec.27, 1966], No.32330/67. Heading G3N. A control tape for a knitting or other machine e.g. weaving loom is produced from an original by colour recognition circuits which generate light pulses to record the information on photographic film strip. An original is prepared by inserting on a 2 x 2 m/m grid, colours e.g. red, green, blue appropriate to the needles to be selected each of which colours are sensed by photo-cells or photo-transistors sensitive only to that colour. If no colour is inserted, the base surface of the original (normally white) causes all the photo- . cells to give through co-incidence circuits a signal corresponding to the base colour on which the pattern is to be produced. Black may be inserted to give no signals, which condition may control one or more operations of the machine. The signals are passed to a circuit Fig.3 (not shown) one for each colour which produces identical pulses which are fed a terminal e.g. 65 for red and passed through a reversing Schmitt trigger circuit e.g. 68 and an amplifier 76 to a line 77 to which may be connected a light pulse generator to record the information in the film. If signals are present on all terminals 65-67 an AND gate 91 through amplifier 95 passes a signal to line 96 and through resistors 103, 104 &c. and reversing amplifiers 105 to inhibit the signals from reaching lines 77, 81, 85. If signals appear on two terminals e.g. 65, 66 this represents a spurious condition and no signal output is given as the signal on say terminal 65 into resistor 75 is opposed by the signal on terminal 66 reversed in amplifier 105, with the opposite condition applying with respect to the input to resistor 79. A gate 97 gives for each pulse on lines 77 &c. an output on terminal 200 which is fed through terminals (129 &c.) Fig. 5 (not shown) and compared with a reference pulse on terminal (126). In the absence of an output on terminals (129 &c.) the generation of light pulses is inhibited and a hold signal is given to arrest the scanning device to enable the fault to be corrected. For machines requiring operation of circuits other than that of the colour recognized, a colour converter furnishes signals other than the one indicated on the pattern e.g. a signal on terminal 65 provides outputs on terminals 122-124 but not on terminal 125. Magnetic or punched tapes may be used in place of photographic film. Other numbers or arrangements of colours may be employed.

Title: Improved source of radioactive energy, and method of producing the same
IPC: G21G4/06
Filed: 1955-11-11
Abstract: A source of radioactive energy consists of a solid shaped body made by compressing carbon, active carbon, or graphite impregnated with radioactive material.  The carbon may be mixed with powdered vitreous or ceramic material or metals, e.g. porous aluminium granules, or metal oxides.  The compressed body may be sintered after impregnation with, e.g., cobalt 60, caesium 137 or other isotopes.  The treated carbon body may be coated to render it impervious to gases and liquids, or it may be partly cased with a shielding layer, e.g. of zirconium metal.  The radioactive substance may be in the form of a liquid or gas, when the carbon body is impregnated in vacuo.  After impregnation the body may be treated, e.g. with acid, whereby the activity is concentrated in the core.

Title: Manufacture of carbonyl compounds by oxidation of olefines
IPC: C07C51/25
Filed: 1960-09-26
Abstract: Carbonyl compounds are obtained by oxidising an olefine with oxygen or a gas containing free oxygen and a liquid aqueous catalyst containing a redox system in the reaction and/or regeneration zone in a co-current, the total drop in pressure being distributed along the reaction and/or regeneration zone so that the pressure is not substantially reduced in the initial part of the zone or zones, but is reduced in the direction of flow after the partial pressure of the starting materials is reduced.  The usual noble metal catalysts and redox systems are used and the process is applied to the conversion of (1) ethylene into acetic acid and acetaldehyde; (2) propylene to acetone and propionaldehyde; (3) butylene to methyl ethyl ketone and n- or isobutyraldehyde; (4) butadiene to di acetyl and croton aldehyde. Mixtures of olefines can be treated, and either or both of the reactants can be diluted.  Specifications 898,790, 900,829, 922,694 and 938,836 are referred to.
