IPC: B22D11/00
Filed: 1952-03-17
Abstract: 729,555. Continuous - casting machines. BRENNAN, J. B. March 17, 1952, No. 6846/52- Class 83 (1). A method of casting and bonding molten metal on a strip 6 consists in passing the strip through an enclosing die having an orifice 8 for the metal in a heated zone, one of the die surfaces being movable to drive the strip. The molten metal is fed from a crucible 1 to a constant-head crucible 2 heated to a constant temperature by high-frequency coils 7. The metal flows to a die opening 8 heated to a constant temperature by coils 7a. A steel strip 6 is cleaned by reducing gas-flames 15 and fed by magnetic belts 9 to the die 14 where it is heated to 1950-2000‹ F. A continuous belt, a large hollow roll, or synchronized rolls may replace the belts 9. Cooling coils 18 chill the strip 6 after the metal has been deposited thereon. Either the die 17 or the belt 9 is recessed to accommodate the strip. The die 14 may be removable and adjustable in width and thickness. The strip coil 6 and the apparatus may be enclosed in a deoxidizing atmosphere. The die parts may be of graphite. In a modification, the base strip 43, Fig. 2, is passed over a hollow roll 40, which may be grooved or flanged and made of graphite, anodized aluminium, carbon, quartz, metal or ceramic material, and which is driven by rolls 50. The apparatus may be used in conjunction with the apparatus disclosed in Specification 688,598.

Title: Improvements in or relating to centrifugal machines for separating solids and liquids
IPC: B04B1/20
Filed: 1930-03-03
Abstract: 344,658. Centrifugal machines. DUPUIS, F., 118, Rue de Montignies, Charleroi, and ATELIERS J. HANREZ, SOC. ANON., Monceau-sur-Sambre, both in Belgium. March 3, 1930, No. 6921. [Class 23.] Density separators; discharging.-A centrifugal drum for separating solids and liquids has a cover with discharge ports for the clarified liquid, and for the solid matter; the ports for the solid matter are normally closed and are opened by the pressure of the solid matter forced upwards by a worm within the drum. The sleeve 2 on the stationary tube 1 is supported in ball bearings and carries arms 6 with bars 7 to which the worm 5 is attached. The drum 8 is carried on the spindle 10 and is provided with an exterior worm 13. The cover 16 of the drum has ports 24 communicating with the conduits 25 for the clarified liquid. Ports 21 are also provided in the cover near the periphery of the drum and are normally closed by lids 22. The machine is driven by a belt on the pulley 28 ; the worm 5 is driven through bevel gearing 31 and the drum 8 is driven at a different speed from that of the worm 5 through bevel gearing 33, 35, 37. The liquid for treatment passes through the tube 1 to the bottom of the drum 8, and then rises during the separating process. The clear liquid passes out by the ports 24 and conduits 25 to the collecting chamber 26 from which it is drawn by the pipe 27. The solids pass into the ports 21 and remain there under pressure produced by the action of the worm 5. This tends to expel additional liquid from the accumulated solids until the pressure increases sufficiently to raise the lids 22. The solids are then projected against the stationary casing 14 and travel down the worm 13 to discharge openings 15. In a modification the lids 22 are replaced by spring-controlled slides which normally hold the ports 21 closed. In another modification where the discharge ports for solids are arranged below the upper end of the separating vessel, the upper part of the worm 5 is directed in the opposite direction to the lower part. Vanes may be attached to the exterior of the drum 8 to keep the casing walls free from solid deposits.

Title: Improvements in or relating to exothermic compositions
Inventor: ANDREW ALFRED TRESHAM
IPC: C22B5/06
Filed: 1958-03-05
Abstract: A composition for use in the production of castings, ingots &c., from molten metal consists of aluminium or a comparable reducing agent, a quantity of oxidizing agent stoichiometrically insufficient to combine with all the reducing agent present, and a small proportion of a fluoride, the composition having a bulk density below 1.25 and being in the form of a highly porous mass or in a form which on heating is converted to a highly porous mass.  The low bulk density may be obtained preferably by incorporating in the composition a highly porous filler material such as granulated coke, sawdust or granulated furnace aggregate of density below 1, but an alternative is to incorporate in the composition a readily hardenable binder, such as a synthetic resin of, for example, the phenol-formaldehyde, urea-formaldehyde, melamine-formaldehyde or epoxy types, with possibly a suitable catalyst for curing, and aerating the mixture either mechanically or by generation of gas within the mass, e.g. by the decomposition of a bicarbonate or ammonium nitrate.  A polyurethane foam may also be used as the binder.  Another method of obtaining low bulk density consists of including in the composition a material of low melting point such as natural or synthetic resin or wax, or a solid material which volatilizes at low temperature such as naphthaline or hexamine, compacting the composition to the desired shape and then stoving at a temperature not exceeding 200 DEG C. Specifications 627,678, 769,719, 772,273, 774,490, 774,491 and 775,380 are referred to.

Title: Improvements relating to coin sorting machines
IPC: G07D3/06
Filed: 1932-03-11
Abstract: 388,220. Coin-sorting apparatus. BYRNE, E. L. W., 329, High Holborn, London.-(Brandt Automatic Cashier Co. ; Watertown, Wisconsin, U.S.A.) March 11, 1932, No. 7338. [Class 116.] A coin-sorting machine comprises a rotating selector disc which delivers coins one at a time to a distributer situated thereunder and rotating in synchronism therewith, under which is situated a sorting member having apertures of varying widths. In the embodiment shown in vertical section in Fig. 1 and in plan and partly in section in Fig. 2, a tilted hopper, having a cylindrical wall 1 and a slanting bottom wall 2, has mounted within it a distributer 3 and a selector disc 4 directly attached by screws or other members to the upper end of the distributer so as to form a unitary structure therewith. Between the distributer and the outer portion of the selector disc is a ring 5 seated upon a shoulder 6 in the hopper and held in position by the removable portion 7 of the hopper which is attached to an outer ring 8 by means of tie bolts 9 extending through notches in this ring and in the ears of the hopper. The hopper is provided around its lowermost side with an upwardly projecting portion 10 which carries an annular slide 11 held in contact with the inner sides of the hopper by a spring 12 which has its ends fastened to the slide and is hooked beneath a projecting member 13 carried by the hopper extension 10, the slide thus being able to move upward if coins crowd below it. The lower face of the slide is bevelled so that coins thrown into the hopper are presented to the selector disc in a flat manner, and are carried round in notches 15 in the outer edge thereof. A spring-urged finger 16 prevents the coins from being lodged in pairs in the notches, and also removes crooked coins. In its upper portion the ring 5 is provided with an aperture 19, above which is a guard-plate 18 to prevent coins other than those carried in the notches from falling through the aperture. As shown in Fig. 6, which is an edge view of the distributer and associated parts, coins carried in the notches 15 on arriving at the aperture 19 fall through it into the pockets 20 of the distributor 3, in which, on account of the inclination of the upper portion of the trailing sides of the pockets, they assume a vertical position and are carried around the channel-like ring 24, shown in perspective in Fig. 7, until in the lowest portion thereof they reach the stepped cut-outs 25. Here the coins drop through the appropriately sized openings and pass through slots or shoots in the sorting head 27 into the coin-receiving trays 29. For driving the machine there is provided a relatively large fibre gear 31 which is urged by leaf springs 33 against a metal washer 32 adjacent to the distributer, thus providing a yielding drive which permits relative sliding under abnormal conditions. The gear 31 is driven by gearing from an electric motor 39.
