Title: Improvements in or relating to conveyors
IPC: B65G25/00
Filed: 1924-10-15
Abstract: 223,578. McKee, W. Oct. 16, 1923, [Convention date]. Link-work.-In conveyers for conveying hot bars from a rolling mill &c. of the kind comprising a set of stationary bar-supporting members 17 between which is arranged a set of members 18 reciprocated vertically and horizontally, means are provided for regulating the intermittent movement of the material conveyed. The members 18, Fig. 1, are united by beams 19 each of which is pivotally connected at each end by a link 23, Fig. 2, to the shorter arm of a bell-crank lever 21. The upper end of the levers 21 are pivotaliy connected to rods 39 which are reciprocated by eccentrics 37 on a shaft 34 driven through reducing gearing by a motor 26. The beams 19 are also pivotally connected to a rod 53 which is slidably mounted in a bearing 62 pivoted in a pillar 61 and is pivoted to a block 51 slidably mounted in the link 50 of a Stephenson link motion, Fig. 3, mounted on the shaft 34. By varying the position of the link with respect to the block, the length of the horizontal axis of the elliptical path can be varied and the direction of feed reversed. In a modification the members 18 are divided transversely into two sets A, B, Fig. 1, driven from the same shaft 34, but connected by gearing, Fig. 9, which is so designed that the horizontal movement of set B is less than the corresponding movement of set A. Adjacent beams 19 of the two sets are connected by links 77 to bell-crank levers 79 which are geared together.

Abstract: 1,193,952. Foundry mould composition. BRITISH CAST IRON RESEARCH ASSOCIATION. 1 June, 1967 [2 June, 1966], No. 24627/66. Headings C3C and C3N. A foundry core or mould composition comprises: sand, primary and secondary bonding agents that react together to set the mixture, water, and a surface active agent. The surface active agent produces a foam which allows the mixture to flow during pouring, the foam having a limited life which is related to the reaction time of the bonding agents, so that the foam remains until after pouring but collapses before the bonding agents react together. The surface active agent may be an anionic octyl sulphate. The bonding agents may react so as to evolve a gas. The primary bonding agent may be sodium silicate, and the secondary bonding agent may be calcium silicide with or without dicalcium silicate: on reaction hydrogen is formed and the sand mass becomes permeable. Specification 1,086,241 is referred to.

Abstract: 847,053. Transformers; changing waveform. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 31, 1958 [Aug. 2, 1957], No. 24695/58. Class 38 (2). A transformer having its primary 10 (Fig. 1) and secondary 13 linking the centre limbs of two magnetic cores 1, 2, of rectangular hysteresis loop material, is provided with fine wire control windings 5 and 6 wound in opposition on the centre limbs 3, 4 of the cores. When an input of rectangular waveform is applied from source 21 (Fig. 2) to the primary, the duration of the output waves depends on the current in windings 5, 6 supplied by source 24 and hence on the voltage of source 24. The Specification states that the system may be used for the regulation of the voltage of transistor supplies by varying the duration of the signals which are to be rectified to produce the D.C. supply. The cores may be of ferrite or other material having a rectangular hysteresis loop and the transformer may be designed to match the impedance of the source 21 to that of load 23.

Title: Improvements in or relating to the deironing of chromium ores
IPC: C22B34/32
Filed: 1946-08-22
Abstract: A method for de-ironing chromium ore consists first in partially reducing the ore, for instance in an electric oven, by means of metallic chromium, e.g. in the form of ferro-chromium, preferably in the presence of a flux such as lime, separating from the overlying slag the metallic phase rich in iron, formed in the course of this operation, and then allowing said slag to freeze, thereafter crushing it and submitting it to a magnetic sorting operation to separate the metallic inclusions from the slag.  The ferro-chromium preferably contains 60 to 80 per cent chromium. The quantity of reducing agent employed in the reduction of the ore may be such that the ferro-chromium finally obtained after reduction contains more than 20 per cent chromium.  Ferro-chromium in which the chromium is greater than 95 per cent may be obtained by submitting the ore to the aforesaid treatment and then reducing the de-ironed ore with aluminium or carbon.  The deironed ore may be reduced in two stages by first causing silico-chromium with a silicon content of below 40 per cent to act upon it, with or without violent intermixing, in the presence of a base such as lime, and forming ferro-chromium having 95 per cent chromium, and then submitting preferably through violent intermixing the slag thus obtained to the action of silico-chromium having greater than 50 per cent silicon.  The latter is prepared by the action of quartz and carbon, e.g. in an electric oven, on part of the de-ironed ore to be reduced, the silico-chromium, poor in silicon, obtained in the course of this second stage, being used for treating the de-ironed ore in the first stage of the reduction operation upon another portion of de-ironed ore.

The stops consist of double-armed supports 122 mounted on the shaft 13 of the arms 29 in such a manner that they move laterally with the arms 29 without partaking of their swinging movement. To the supports 122 are fixed sheet holding-down devices which may consist of spring or gravity pressed pivoted triangular flaps 123, Fig. 3, or fixed angular pieces 124, Fig. 4, which enclose the sheet edges from above and are perforated to receive wires or rods 125 projecting over the corner of the top sheet. Or a brush with bristles touching the corner of the pile may be fixed to each support 122. The blast pipes 127 for loosening the edges of the pile may be arranged. on the supports 122, or on the arms 29. A blast may also be directed under the top sheet before it is held by the grippers 75. This blast is directed by a nozzle 131 integral with each gripper 75, or by means of similar nozzles mounted on the gripper carriages by the side of the grippers. The supply of air to the blast nozzles is controlled by a rotary valve which is intermittently rotated through quarters of a revolution by cams on a control disc similar to that described in Specification 274,453.

In the continuous polymerization of vinyl chloride alone or with a minor proportion of another monomer at low temperatures, i.e. not greater than the boiling point of the monomer under normal atmospheric pressure, in the presence of a catalyst comprising an organoboron compound and a fluidizing substance capable of keeping the reaction mass highly fluid even at high degrees of conversion, the separation of the polymer and recovery of unpolymerized monomer by contacting a continuous stream of the reaction mixture with a stream of washing water at a temperature of from 10 to 30 C. containing a small quantity of a substance capable of raising the pH of the water to at least 8, rapidly evaporating the unreacted monomer and fluidizing substance and simultaneously separating the polymer by centrifuging, and eliminating the last traces of catalyst from the evaporated monomer and fluidizing substance before recycling the monomer. Specifications 1,086,497 and 1,128,172 describe fluidizing substances. Substances which raise the pH may be an alkali or alkaline earth hydroxide or salt. The last traces of catalyst are preferably removed from the evaporated monomer and fluidizing substance by washing the mixture with a highly basic organic substance such as amine. The exemplified catalyst is triethyl boron, ethyl ether and cumene hydroperoxide, and the fluidizing substance ethyl chloride. The polymers dissolved in cyclohexanone may be spun into fibres.
