Title: Improvements in and relating to dough dividers
IPC: A21C5/04
Filed: 1949-05-12
Abstract: 659,147. Dough-dividers of the hopper-andplunger type. BAKER PERKINS, Ltd. May 12, 1949, No. 12669. Convention date, Dec. 28, 1948. [Class 87 (ii)] The sides of the dough-box 4, within which reciprocates the plunger 6, converge inwardly toward each other from the edges of the dough inlet 3, the box sides being curved in crosssection and joining each other to form a continuous curved wall. The plunger is of substantially the same cross-sectional shape as the box. As shown in Fig. 3, this shape is semicircular. The adaptor 8, disposed between the box and the measuring-head 34, is divided by a rib 39 into two channels which lead to two outlets 38 registering with bores 9 in the measuring head. The capacity of the box and adaptor when the plunger is at the end of its stroke may be at least as great and preferably greater than the amount expelled at each stroke, so that each piece of dough receives at least two compressions. The plunger is reciprocated by an electric motor 14 via speedreducer 15, belt 18, crank-shaft 17, rod 21, lever 23 and link 25. The lever 23 is pivoted at its lower end to a block 24 slidable on fixed rods 24c, the block being urged to the left by a compression spring 24a, the setting of which is regulated by means of a screw 24b. The reciprocating knife 5, which cuts off dough fed from the hopper 1 into the box, is operated by the crank-shaft 17 via rod 20, lever 22 (pivoted on block 24) and a link 26 having an adjustable lost-motion connection 27, 30, 31 with the lever, whereby the dough cut-off point may be varied. The dough-piece-receiving conveyer 13 is driven from the speed-reducer 15. The measuring head is driven from the crank-shaft by means of a link 19.

Title: Improvements relating to cartons or like containers
IPC: B65D3/10
Filed: 1933-05-02
Abstract: 419,148. Cartons or like containers. PAGE, J. E., 350, George Street, Sydney, Australia. May 2, 1933, No. 12800. [Classes 18, 66, and 125 (iii).] Cartons or like containers, preferably made chiefly of paper board or similar material and suitable for use in packaging ice cream, are adapted to be shipped in nested or compact knockdown condition and include a body member B, and a cover member for the upper end of the body member, said cover member C, comprising a relatively stiff rim portion 30, and an associated cover piece 34, the rim portion being adapted to be slipped on to the body portion and automatically retained thereon by the locking interengagement between the rim portion and the body member, and the cover piece being removable to permit access to the contents. The body portion B may be cylindrical, oval, or polygonal and is formed from a suitably shaped shaped blank 10 with an out-turned flange 11 at its upper end. The flange may be slit at intervals to form a number of depending tabs 13. Similarly the rebent bottom portion of the body is cut at 14 to provide tabs 15. The body blank is bent to shape and the overlapping edges secured by staples 16, thread stitching or other means. The body may have a number of vertical score lines 17 to permit it to collapse for lateral stacking as shown in Fig. 9. The bottom end member comprises a metal rim 20 with a side wall 21 and inwardly extending flanges 22, 24. A bottom piece 23 of strong paperboard rests on the flange 22. The bottom end of the body member is pushed into the rim 20, and the tongues 15 spring outwardly and engage under the lip 24, thus permanently securing the bottom member to the body, the lower end 18 of the body member forming a tight joint against the bottom piece 23. The cover member C is attached to the body member in a precisely similar manner but has a removable cover piece 34, the periphery of which is normally engaged under the bead 33 on the cover rim 30, but which has a small arcuate score 36 which may be punctured to provide a tab 37 by which the piece 34 may be removed to permit access to the contents. In a modification the tabs 15 at the bottom of the body member are turned alternately inwardly and outwardly, the out-turned tongue engaging as before under the rim 24, and an inset disc being inserted into the container to hold the inturned tongue between itself and the disc 23. The containers may be shipped with the bodies in nested condition, bottom and cover members being also nested as shown in Fig. 8, or in the case of a cylindrical container, the body members not being suitable for nesting may be collapsed and stacked laterally. The side wall portions 21 of the bottom end piece 20 may be inclined to conform to the shape of a conical body member, but the side walls 31 of the cover rim 30 are vertical and the lip 32 is consequently deeper thus affording a good finger grip for lifting the container.

Title: Improvements in or relating to electric transformers
IPC: H01F27/36
Filed: 1955-05-03
Abstract: 793,051. Transformers. HATFIELD, R. H. Aug. 3, 1956 [May 3, 1955], No. 12867/55. Class 38 (2). In a transformer comprising a primary winding a, b and two secondary windings c, e and d, e, joined together at e and wound in opposite directions electrostatic coupling between the primary winding and each of the two secondary windings is equalized by one or more interwinding electrostatic screens. Figs. 4a, 4b show that when the screen is a half-turn continuation of primary winding a, b (shown dotted), the voltages between the conductor formed by the last half-turn of winding a, band the screen, and the two secondary windings c, e, d, e (or their innermost turns), are in both cases zero for the first half of the secondary winding (or turn) and of a constant value x for the second half, as a result of the voltage induced in the screen. Thus interwinding capacity does not result in different charging currents to affect the terminal voltages of the secondary windings. Similar results are obtained when the screens are formed by half-turn continuations of the two secondary windings (Fig. 5, not shown), and by quarter-turn continuations of the primary winding and one secondary winding and a threequarter turn continuation of the other secondary winding. The windings may be copper tapes separated by polythene tape g and wound on the central limb f of a ferrite core.

Title: Improvements in phosphorus recovery
IPC: C01B25/02
Filed: 1953-05-11
Abstract: <PICT:0743019/III/1> Phosphorus is recovered from calcium phosphate-bearing material by preheating, by means of combustion heat, to 1200-1300 DEG C. a charge comprising calcium phosphate-bearing material, silica and solid carbonaceous material, placing the charge, without substantial dissipation of heat absorbed during preheating, on the surface of a molten slag bath, maintaining the slag bath by means of combined electric arc resistance and slag resistance heating at a temperature sufficiently high to provide substantially all the heat required to reduce the phosphorus of the calcium phosphate, with vaporization of phosphorus, and to melt calcium silicate, and collecting vaporized phosphorus.  A finely divided mixture of calcium phosphate, silica, and coal or coke is fed by hopper 22 to rotary inclined kiln 20 where the mixture is preheated.  The resulting sintered granules pass through hopper 23 to hoppers 16 provided in electric furnace 10, which has refactory hearth, walls, and roof 12, 13, 15, and electrodes 11, with sealing in the roof opening.  The portion of wall adjacent the feed hoppers slopes at an angle equivalent to the angle of repose of the charge and is preferably stepped.  The vaporized phosphorus and CO pass by conduit 19 to condenser 14 where water sprays 26 condense the phosphorus, while remaining CO is passed by pipe 27 to kiln 20, wherein it is burnt with air added at 28 to provide the necessary heat.  To maintain the necessary temperature, e.g. 1550 DEG C., the molten slag bath should never be less than 3 inches deep, and the electrodes should be positioned (by automatic adjustment) to from 1/2 inch above to 2 inches below the molten slag surface. In addition the bed depth of the charge is a maximum of 15 inches immediately adjacent the electrodes to prevent pressure build-up of released gases, and the arc should be not longer than 1/2 inch.  The kiln may be replaced by a travelling hearth furnace.

Title: Process for the production of film consisting essentially of a tetrafluoroethylene polymer
IPC: B29C67/04
Filed: 1945-05-25
Abstract: A process for the production of films comprises pressing a powdered polymer of tetrafluorethylene into a preform, baking the preform at a temperature of 327-500 DEG  C., cooling, separating a self-sustaining film therefrom, heating the film to 327-500 DEG  C. and quenching the film in an inert liquid at a temperature below 250 DEG  C.  The film thus formed may be subjected to pressure between rolls such that it has 40-80 per cent of its original thickness. The process is applicable to tetrafluorethylene interpolymers.  In the formation of the preform, the finely-divided polymer is subjected to pressures of 50-10,000 lbs. per sq. inch.  Fillers such as mica or barium titanate may be incorporated.  Water at or below room temperature is the preferred quenching agent.  In one example, a ring is pressed from micropulverized polytetrafluorethylene at 1000 lbs. per sq. inch pressure, baked for two hours at 360 DEG  C. and cooled in air.  A tape 0.007 inches thick shaved from the ring is passed through molten heat transfer salt (a eutectic mixture of sodium nitrate and nitrite) at 360-400 DEG  C. and quenched in cold water and rolled to 75 per cent its original thickness.  Films produced as above have properties suitable for electric insulation.  Specification 589,714 (as open to inspection under Sect. 91) is referred to.ALSO:A powdered tetrafluorethylene polymer is pressed into a preform and baked at 327 DEG -500 DEG C. to form a blank from which films or tapes are cut. The powdered polymer may be moulded at pressures of 50-10,000 lbs. per sq. inch.  The film or tape is heated to 327 DEG  to 500 DEG C. and then quenched in an inert liquid at a temperature below 250 DEG C.  The powder may be wetted with a liquid such as ethanol prior to pressing but any such liquid should be removed prior to the baking step.  Powdered mica or metal titanates may be incorporated with the polymer.  In an example, micropulverized polytetrafluorethylene is pressed into the form of a ring under pressure of 1,000 lbs. per sq. inch.  The ring preform is baked for 2 hours at 360 DEG C. and cooled in air.  It is then mounted on a mandrel on a lathe and a tape is shaved from the ring.  The tape is passed through a molten heat-transfer salt e.g., a eutectic mixture of sodium nitrate and sodium nitrite, at 360 DEG -400 DEG C., and then quenched in water.
