Abstract: 830,450. Glass manufacture. OWENS-ILLINOIS GLASS CO. Dec. 12, 1956, No. 37903/56. Class 56. During its passage through the forehearth 13 from the furnace 10 to the delivery point 14 molten glass is homogenised by being subjected, inter alia, to the action of stirrers 26 which produce coaxial vortex flow from the surface of the glass. The invention is described with special reference to the mixing with the molten glass of a coloured frit from a supply 16, but it is of general application. The molten glass is first subjected to the action of rotary screw stirrers 24 and then to gas from bubblers 25, after which it passes under a vertically adjustable skimmer dam 29 and, after treatment by the stirrers 26, passes over a dam 31 and is treated further by other rotary screw stirrers 27. In the form shown in Fig. 1 the stirrers 24 and 26 and the dam 29 operate in a well 28, but this may be omitted. Two constructions of stirrers 26, which are made of metal, are shown in Figs. 12 and 14 ; that in Fig. 12 comprises a hollow shaft 50 ending at its lower end in a hollow loop 55. A concentric tube 59 is mounted within the stirrer so that cooling fluid may be circulated therein. In Fig. 14 the hollow shaft 70 communicates at its lower end with a hollow transverse member 71, both hollow members containing a cooling-fluid pipe 72, 73.

Title: Methods and apparatus for pack annealing or cooling heated workpieces
IPC: B21B43/00
Filed: 1962-10-10
Abstract: <PICT:1011748/C6-C7/1> In a method for pack annealing or cooling heated workpieces, the latter are sequentially stacked on edge to form a pack which is advanced through the annealing zone, the leading workpiece being successively separated from the pack and moved over a cooling bed. While traversing the annealing zone the workpieces are supported at a plurality of points on their lower edges, the points of contact being moved as the pack progresses to avoid localized chilling. As shown in Fig. 1, lengths of material, arriving in sequence at zone A, are stacked on edge on rolls 80 the axes of which are at an angle to the direction of movement of the workpieces, and the pack is caused to advance through annealing zone B by intermittent rotation of rolls 80; the latter have frusto-conical end portions 82 by means of which the leading member of the pack is accelerated, being thereby separated and transferred to rotating rolls 155 forming cooling zone C.  As shown in Fig. 2, which represents one unit of a number in parallel, workpieces 160 arrive on rolls 23, and are lifted by elevator 20 to stepped platform, down which they progress by the intermittent action of rack 33 to join pack 16, being held in position by retaining arm 43.  The front of the pack is <PICT:1011748/C6-C7/2> initially supported by chain-mounted dog 120, which when a stable pack has formed is traversed to support the rear end thereof when the supply of workpieces has ceased.

Abstract: 849,158. Refrigerating. HEAT-X Inc. Dec. 20, 1956 [Dec. 20, 1955], No. 38871/56. Class 29 In a compression system the expansion valve 18 is controlled by a thermal element 50 responsive to the temperature of vapour from evaporator 20 after it has been heated by hot liquid refrigerant in exchanger B. The setting is such that saturated refrigerant leaves the evaporator, super-heating taking place in exchanger B. The vapour is further heated by hot liquid in exchanger A. At low loads, the resulting low pressure condition allows opening of a valve 53 which admits hot gas from the compressor exhaust to the inlet of exchanger B where it mixes with the cold vapour to increase the suction pressure. To avoid the effects of pressure drop across the evaporator, the environment of bulb 50 and valve 18 are connected by a pressure-equalizing conduit 52.

Title: Improvements relating to the making of ceramic masses
IPC: C04B33/02
Filed: 1930-12-31
Abstract: In mixing ceramic masses binding material in the form of a cloud of dust or mist is incorporated with the foundation material.  The binding material may be transformed into the cloud of dust or mist with the use of gas or gas and liquid.  The binding material is reduced to a state of colloidal fineness by grinding either in the dry state or with liquid.  The mist may be sprayed into the foundation material by nozzles, whereby the grains of the material become coated with a thin skin of the binder.  The foundation material may be chamotte, corundum, quartzite, magnesite, chromite or the like.  The binding agent may be of the same or a different material.  The binding material may contain liquefying media, such as alkalies, ammonia, and humic acid; mineralizors, such as phosphoric acid, boric acid, hydrochloric acid, tungstic acid, and other acids, salts and bases; catalyzors, such as iron, fluorspar, cryolite, bauxite, and alumina; and fluxes, such as alkalies, alkali silicate, sulphates, borates or nitrates, and carbonates of the alkaline earths.  In addition organic materials of high molecular weight such as dextrin, albumen, oils, soap, tar, mucin, and the like may be incorporated in the binding material to reduce the friction between the particles so that a dense produce may be obtained on moulding under pressure.  Furthermore additional materials which are to react with the mass may be added by converting them into a mist with a liquid which may itself react chemically with the mass.  For example to clay, chamotte, zirconium, zirconia or the like is added in the form of a mist a mineral glue made from aluminium phosphate and phosphoric acid, sulphite waste or dextrin, and molasses or the like; and dust-like Thomas meal or aluminium phosphate in the form of a cloud.  The non-plastic mixed mass is moulded by pressure with or without heating.  Large refractory pieces may be made by striking or stamping in non-vibrating moulds stiffened by T or U irons.  In working with coarsegrained masses the mass is scattered below the stamper for each blow in a layer only one grain thick.  To smooth the shaped pieces they are dipped in a solution of an electrolyte or a liquid which disperses the binding agent.  The surface of the shaped piece may be covered with a skin of the foundation material which is applied as a colloidal solution.  Specification 264,192, [Class 22, Cements &c.], is referred to.
