Title: An improved method of and apparatus for the heat-treatment of substances, and the recovery of decomposition products therefrom
IPC: C10B49/04
Filed: 1949-10-12
Abstract: 693,214. Carbonizing apparatus; retorts. STORRS, K. L. Oct. 12, 1949 [Oct. 15, 1948], No. 26185/49. Class 55(i) [Also in Group XXX] Decomposition products are recovered from substances under heat treatment in the absence of combustion-supporting fluid by subjecting the substance within a heating zone to a controlled temperature no greater than will release liquid products which are removed at different temperatures and delivered to recovery means at temperatures above those at which the products congeal but below their vaporizing points so that no condensers are required. Particulate bituminous coal is fed to the end of an elongated retort 10 from an elevator 53 and shoot 54. The retort comprises two overlapping base sections 11-1, 11-2, and a heat-insulating cover 12, the base sections being composed of heat resistant blocks 14 sloping sideways to permit gravity flow of liquids into a longitudinal discharge conduit 56 divided into sections 59. Wire mesh troughs 16 are positioned above the base and beneath electrical heating elements 23. To ensure rapid uniform heating of the particles, the base sections, to which the troughs are secured by their imperforate side plates 17 and upstanding transverse supports, are subjected to vertical vibration by means of eccentrics 27 driven by a motor 31 and connected through rods 41 to vibrating rods 38 secured at their ends in frames 34. Horizontalvibrating motion for conveying the particles is also imparted to the base assembly by similar frames 35:: by means of a mechanism 46. Both vertical and horizontal vibrations may be independently adjusted as to stroke and speed. The discharge conduit may be divided laterally as well as longitudinally to facilitate segregation of the products which tend to stratify. To obtain high temperatures coke, the char from a carbonization up to 750‹C is extruded into logs which are subjected to coking temperature in a second retort without vertical vibration. The retorts may be heated by gas, oil, or powdered coal and combustion products exhausted in the same direction or counter to the movement of the substance treated. In one embodiment liquid, e.g. petroleum, is heated in a shallow pan below electric heating elements in an oven having a sloping floor leading to an inclined recovery conduit having trapped discharge pipes at intervals for collecting liquids of varying density which stratify in the conduit.

Filed: 1924-11-03
Abstract: 243,147. Western Electric Co., Ltd., and Deloraine, E. M. Nov. 3, 1924. Thermionic generators.-A thermionic valve has two electrodes F1, F2 acting alternatively as anodes and cathodes, being kept hot by the electronic bombardment to which they are subjected while acting as anodes. Alternating current, say of 50 cycles per second, may be fed from a source D to the main electrodes. Current through the two grids G1, G2 is restricted by resistances R1 . R2. Only the grid nearer to the electrode F1 or F2 which is temporanly acting as cathode is effective. Reaction coils are arranged so that the valve generates oscillations. A bank of thermionic tubes may be similarly connected; or one or more groups of three or more tubes may be supplied with three or six-phase current. When the system is used in signalling, the anode bombardment must be kept constant during the " sending " and " marking " intervals.

Abstract: 976, 687. Electric selective signalling systems. STANDARD TELEPHONES & CABLE Ltd. July 4, 1963, No. 26459/63. Heading G4H. In a system for measuring an unknown voltage V on a logarithmic scale (e.g. in db's or nepers) the unknown voltage is registered on a first capacitor C 1  which is then sequentially discharged by charge sharing with a second smaller capacitor C 2 , the smaller capacitor C 2  being discharged between each charge sharing step, and the number of charge sharing steps n necessary to reduce the voltage across the first capacitor C 1  to below a reference voltage V r  is counted. It can then be shown that if k is the factor by which the voltage across the first capacitor is reduced at each charge sharing step, then log V/Vr = -n log k. Thus if, for example, -20 log k = 0.1, and the logarithms are to the base 10, then the number n is a measure of the unknown voltage V relative to the reference voltage V r  in steps of 0.1 db's. In order to measure A.C. voltages by this method rectification is necessary and a block diagram for this which also automatically attenuates the input to bring it into the desired range is described (Fig. 2 not shown).

Heading E1S. [Also in Divisions A6, B7 and G1] A cooling tower &c. is cast in shuttering raised by workmen in climbing staging, concrete &c. being raised by a tower crane in the centre of the structure, the shuttering being positioned by reference to the crane to determine the shape of the tower. The crane is stayed from the cast part of the tower by stays in the form of bights of ropes removable from the crane end. The shuttering is centred on the crane by means of a circular frame surrounding the crane up which it is moved on rollers and round which runs a carriage to which is fastened one end of a setting- out tape the other end of which is held against the shuttering. Mechanism for indicating the correction for the crane being off centre is provided (See Division G1). The ends of upper and lower stagings 59, 58 Fig. 12 from which the shuttering is positioned and removed are mounted on scaffoldings 150 mounted at intervals round the tower and having a lowermost platform 40 and supported on channels 41 secured by pulse 39 to the cast part of the tower. Each scaffolding has two channels back to back on each side of the tower wall and the bolts 39 pass between the channels. A safety cage is formed by hoops 51-53. The stagings are hung on chains so that they can be maintained horizontal. The stagings 59, 58 each comprise two telescopic parts 74, 75 Fig. 24 the total length of which is adjustable according to the circumference of the part of the tower being constructed. The outer telescoping part 75 is provided with transverse boards which are removed as the staging is shortened. Boards 85, 86 on brackets close the gap between the stagings and the tower wall. A series of ladders hung on hooks and chains from the tower wall provides access to the stagings from the ground and each has a safety cage and a platform 89, Fig. 36 having a manhole 96 in two corners of which are sockets 97, 98 for receiving the lower ends of the next higher ladder. The highest ladder entering the staging scaffolding is telescopic and has a telescopic cage. The shuttering panels are wooden and comprise plywood on a wooden frame and have tongue and groove edge arrangement or metal panels 114 Fig. 50 have a wooden backing piece 115. The panels are connected by walings which are connected to soldiers by hook bolts the bottom bolt being adjustable to allow for the slope of the tower. The walings comprise pairs of members between which pass ties which connect shuttering on each side of the wall. The scaffolding is raised at each stage by purchases on bolts in the tower wall. A workmens walkway Fig. 53 secured to the capping beam 39 of the tower is used for dismantling the scaffolding which with the shuttering is lowered to the ground by the tower crane.
