Abstract: 371,880. Purifying alloys. BAILEY, R. W., 20, Grange Avenue, Hale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 26, 1931, No. 2571. [Classes 72 and 82 (i).] In pouring molten metal into a mould the orifice of the ladle &c. 2 has a sleeve 5 through which the stream 3 of metal passes and to which neutral or reducing gas is supplied by a pipe 6. The sleeve may be discontinuous and connected by open-work 13, Fig. 4, or provided with one or more windows 8, Fig. 2, for inspection. The sleeve may be telescopic and be adjusted so that its end is just above the rising metal or it may have a lower thin-walled section which is melted by the rising metal. In this case the sleeve 5, Fig. 5, may be made of, or be coated with, slag forming material or be made of the same metal as that being cast, or of a metal which it is desired to add so as to form an alloy or act as a deoxidizer &c. Holes 15 for the escape of the gas or an adjustable muff 14 or both may be provided. If a muff only is used it is also supplied with gas. The sleeve may be vertically corrugated and strengthened internally or externally or both by rings or helices attached by spot welding or otherwise. The gas escaping from the sleeve and muff protect the surface of the metal in mould 1 from oxidation.

Title: A process for the production of bubble-free bodies from synthetic materials
IPC: C08J7/16
Filed: 1944-02-11
Abstract: Producing bubble-free structures by wetting high molecular polymerization or condensation products with a minimum (e.g. 5 to 15 per cent) of low molecular materials capable of being polymerized or condensed, and wherein the materials in the wetted condition are immediately compressed to expel the air, and the resultant mass is converted into a solid form by polymerizing or condensing the low molecular materials.  The high and/or low molecular materials may be loaded with fillers, e.g. carbon black, or colouring materials or softening agents.  In the examples: (1) polymethyl methacrylate is wetted with methyl methacrylate containing benzoyl peroxide, compressed in a mould and polymerized; (2) polymethyl methacrylate is sprayed with a dilute solution of benzoyl peroxide, dried, mixed with methyl methacrylate and treated as in (1), the methyl methacrylate may have been stabilised with divalent products; (3) as in (1) or (2), using instead of methyl methacrylate, partially polymerized methyl methacrylate which may be stabilised with hydroquinone; (4) phenolformaldehyde resin is wetted with the pre-condensed products and treated as in (2).  An accelerator, e.g. solutions of hydrochloric acid gas in glycerine is added; (5) phenol resins are wetted with solutions of hexamethylene tetramine in phenol (particularly mixtures of meta-and para-cresol) and treated as in (4); and (6) thin plates of aminoplast are wetted with vinyl acetate or with a methacrylic ester compressed and polymerized into a solid block by heating.

Abstract: 701,481. Roller mills. MIAG MUHLENBAU UND INDUSTRIE GES. Feb. 6, 1952 [Feb. 7, 1951], No. 3122/52. Class 59 In a roller mill comprising feed rollers associated with a feed gate and having automatic or non-automatic devices for engaging and disengaging the grinding rollers, for coupling and uncoupling the drive to the feed rollers, for adjusting the feed gate, and for varying the speed of the feed rollers, means are provided to actuate these devices selectively so that they operate individually or simultaneously, in dependence on or independently of one another. In the form shown, the grinding roller 4 is arranged diagonally of the grinding roller 1 and is adjustable relatively thereto by means of lever bearings 7 connected to adjusting rods 8 which are supported by eccentrics 9 of a rotatable shaft 10. One of the feed' rollers 11 is driven from the shaft 13 by means of a chain wheel drive 14 and drives the other feed roller at a different speed through gear wheels 15, 16, 17. The shaft 13 is driven from the roller 1 by means of a belt drive 18 acting through a friction wheel drive 19, 20 and an intermediate drive 21. To disengage the drive to the feed rollers, one wheel of the chain drive 14 is loosely mounted on the shaft 13 and carries one half 22 of a clutch which is engageable by the other half 23 fixed on the shaft 13. A servomotor 24 is provided which comprises means 28 for engaging and disengaging the clutch 22, 23, means 29 for actuating the pivotally-mounted feed gate 12 or the friction wheel drive 19, 20, and means 30 for actuating the shaft 10. The means 29 is connected by a linkage 31 to a pivotally-mounted twoarmed lever 32 having adjustably mounted on one arm thereof an adjustable rod 34 for actuating the feed gate 12 and having adjustably mounted on the other arm thereof an adjustable rod 37 which, through a pivotally-mounted lever 38, actuates one part 19 of the friction wheel drive. By suitably adjusting the points of connection of the rods 34, 37 with the lever 32 there may take place either an adjustment of the feed gate 12 or an adjustment of the speed of the feed rollers. The feed rollers and grinding rollers are automatically effective by means of the servo-motor in dependence upon the supply of material to be ground. The friction wheel drive 19, 20 may be replaced by exchangeable gears, Fig. 2 (not shown), in which case the rod 37 and lever 38 are omitted. The servomotor means for actuating the shaft 10 and clutch 22, 23 may be replaced by manual means, Fig. 3 (not shown).
