Title: Device for delivering liquids
IPC: G01F11/38
Filed: 1959-10-07
Abstract: 910,169. Dispensing measured quantities of liquid. JAGENBERG-WERKE A.G. Oct. 7, 1959 [Oct. 8, 1958], No. 34002/59. Class 106 (5). A device for dispensing measured quantitites of liquid comprises a measuring vessel 1 which has a single opening 3 for the inflow and outflow of liquid and is movable to register this opening with either an inflow port 9 or outflow port 10, and a retaining device for holding the vessel with the opening 3 and outflow port 10 in register against the action of a force tending to move the vessel to the position in which the opening 3 registers with the inflow port 9. The vessel 1 is secured to a plate 2 mounted for rotary movement on a corner plate 8 so that the opening 3 in the plate 2 can be alternately registered with the ports 9, 10 which are provided in the plate 8. With the vessel 1 in the position shown, liquid is fed in under pressure through the inlets 3, 9, thereby lifting a piston 4 until an air vent 5 is closed by a projection 6 on the piston. A container 21 to be filled from the vessel 1 is then brought on a support 22 into position beneath the vessel 1 which is then rotated by a handle 12 against the action of a spring 13 until the openings 3, 10 are in register and a spring- loaded pawl 16 coacts with an abutment 14 to hold the vessel in this position. Liquid is then discharged into the container 21 by the action of the piston 4 which finally rests on a sealing ring 7 to close the opening 3. The support 22 with the filled container is then withdrawn from the filling position and, in such movement, a roller 20 on the support actuates a lever 18 to release the pawl 16 and to permit the spring 13 to return the vessel 1 to its initial position.

Title: Improvements in or relating to processes for refining metals and alloys
IPC: C21C5/52
Filed: 1935-12-13
Abstract: 472,038. Refining metals and alloys. TRIGGS, W. W. (Buffalo Electric Furnace Corporation) Dec. 13, 1935, No. 34592. [Classes 72 and 82 (i)] A process for refining metals or metalbearing material consists in supplying to a molten bath 16 of the material, an oxidizing reagent consisting of a metal and a metallic oxide heated within a substantially hollow electrode 14 to a temperature above the melting point of the metal to induce an oxidizing action between the reagent and an oxidizable undesirable constituent of the bath to remove such constituent. The reagent is formed in the heated zone of the electrode by supplying thereto a mixture of a metallic oxide and a reducing agent insufficient in quantity for reducing the whole of the oxide, the mixture being heated to a temperature above that at which reduction takes place and above the melting point of the reduced metal. The reducing agent may be carbon whereby an atmosphere of carbon monoxide is maintained in the furnace. The reagent is fed through the cores in the form of briquettes c and drops into the bath as liquid. Substances may be added to the reagent to accelerate or retard its flow and correctives may be introduced either through the electrodes or directly into the bath for maintaining the slag 19 in a permeable condition for the reagent and also to supply an oxide thereto to avoid removal of the metal oxide from the reagent. The reagent should be heated to a temperature of from 400 to 600‹ F. above the melting point of the metal to ensure solution or dispersion of the oxide in the metal. The undesirable constituents of the bath to be removed by oxidation may be carbon, sulphur, phosphorus or manganese. In the making and refining of alloys containing for example iron, chromium, manganese or nickel, oxides of the metals may be introduced through the electrodes. Silicon may be a constituent of the alloy. Examples are given of methods of preparing low carbon ferromanganese, stainless steel, and carbon-free iron.

Abstract: 489,371. Resilient mountings. PIRON, E. H. Dec. 22, 1936, No. 35184. [Class 108 (iii)] A spring device comprises concentric loadimposing and loadreceiving members, e.g. a shaft 1 and base 4, having rubber or like material therebetween adapted to store energy in shear upon relative axial movement of the members, the shear strain remaining substantially constant throughout the material. A constant shear strain may be obtained by varying the axial length with the radius, if the material has a constant shear modulus of elasticity, or by modifying the elastic qualities of the material, or by varying both the axial length and the modulus of elasticity. As shown in Fig. 1, the spring comprises alternate metal cylinders 3.. 3d and rubber cylinders 2 .. 2c bonded together and arranged around the shaft 1 between a stop 9 thereon and the base 4, each rubber cylinder decreasing in height from its inner to its outer surface and the mean height of the cylinders decreasing outwardly of the spring, while the rubber decreases in hardness from the inner cylinder outwardly. The spring is built in segments, preferably semi-cylinders, the metal portions subtending an angle less than 180 and the rubber portions being provided with end projections such as ovals 6, Fig. 2, buttons 7, or rectangles 8 which, when the segments are assembled and compressed, spread between the adjacent opposite edges of the metal segments. In another construction, in order to vary the load-deflection curve of the device in accordance with given requirements, the metal cylinders have end flanges adapted to abut successively stepped portions of a fixed plate which replaces the stop 9, Fig. 1, thus successively rendering inoperative the corresponding rubber cylinders. The metal cylinders may be perforated to permit joining of adjacent rubber cylinders during manufacture.
