Title: Continuous Casting
Inventor: PRITCHARD WILLIAM HENRY
IPC: B22D11/07
Filed: 1966-05-06
Abstract: 1,176,139. Continuous casting; mould linings. ASHMORE, BENSON, PEASE & CO. Ltd. 1 Aug., 1967 [6 May, 1966], No. 20139/66. Heading B3F. In a continuous casting mould, a layer 15, of metal particles welded together and 5-40 thousandths of an inch thick, is built up on the mould surface, at least at the meniscus level of the metal to be cast, by spraying the surface with liquid metal. The layer 15 and mould walls 12 may both be of copper. The layer is applied to dress a mould surface eroded in use or to the surface of a new mould. The layer is porous and permits the flow of oil from passages 16 through porous plugs 18 into the mould interior as a lubricant. This may initially be converted to graphite and close the surface pores but as the graphite burns more oil enters. The mould may be curved but as shown it is formed by planar walls 12 secured together (and water-cooled).

Abstract: 1,214,714. Alpha-sulpho fatty acids. PROCTER & GAMBLE Ltd. 28 April, 1969 [29 April, 1968], No. 20219/68. Heading C2C. [Also in Division C5] Monosodium C 10-22  fatty alpha-sulpho carboxylic acids are obtained by a process comprising: (a) mixing solutions (in a substantially inert solvent) of sulphur trioxide and appropriate fatty acid such that the sulphur trioxide is in molar excess; (b) maintaining the mixture at a temperature up to the boiling point of the mixture for a time sufficient for substantially complete reaction; (c) thereafter partially neutralizing the mixture by mixing it with an aqueous solution of caustic soda, the concentration of the caustic soda solution and the temperature during the neutralization being such that any disodium alpha-sulphocarboxylate formed during neutralization is not precipitated and ensuring that the final pH of the solution is in the range 2À5 to 4À5; (d) separating the solvent from the neutralized solution; (e) cooling the thus concentrated mixture to precipitate the crystalline monosodium compound; and (f) separating the precipitated crystals and washing these with water. A fatty acid of which at least 90% by weight is stearic or palmitic acid or a mixture thereof, e.g. commercial stearic acid or acids from hardened tallow, may be especially utilized in the process. The sulphonation of stearic acid affords a product comprising the corresponding monosodium alphasulpho-carboxylic acid and a small amount of disodium alpha - sulphocarboxylate, residual moisture, stearic acid and volatile matter.

Title: Improvements in and relating to vibratory tools
Inventor: BRADFIELD GEOFFREY
IPC: G10K7/00
Filed: 1953-07-21
Abstract: 798,903. Percussive drills. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 21, 1954 [July 21, 1953], No. 20226/53. Class 124. [Also in Group XXXVIII] A liquid operated siren is used to drive a percussive drill. The rotor 11 of a siren is mounted on a motor driven shaft 12. The stator consists of a substantially conical apron 15 secured by radial members 13 to the outer casing 16. Liquid is pumped to the rotor through a duct 24 and an annular chamber 28 and is returned to the pump through the shaft 12 and a duct 25. The vibrations in the liquid are transmitted to a coupling 18 of metal or of tungsten carbide on which is mounted a tool 19. The coupling is mounted at a velocity node by means of a diaphragm 21, the diaphragm itself being resonant at the operating frequency with a velocity antinode at the centre and a velocity node at the edges. Fig. 4 shows a cross-section of an alternative diaphragm which resonates as a quarter-wave element. The chamber 28 resonates at the operating frequency with a pressure antinode at the rotor end and a pressure node at the right hand end. The chamber 28 communicates with the duct 24 through a constriction 27 which is at or near a velocity antinode. The space between the apron 15 and the casing 16 also resonates at the operating frequency. In a modification shown in the provisional drawing, impeller blades 2 are provided on the shaft 1 to form an internal centrifugal pump which circulates liquid within the siren. The coupling 10 has a length of one wave-length and is mounted between diaphragms at pressure antinodes. In another arrangement, Fig. 5, the stator of the siren is carried by an extension 57 of the shank 55 of the drill so that torsional vibrations are transmitted directly from the stator to the drill by a solid medium. In another arrangement, Fig. 7 (not shown), producing torsional vibrations, the liquid flow through the siren is radial instead of axial. The circulating pump is not shown in Fig. 5, but it may be either internal or external. The liquid may be water, or oil, or other liquid of low viscosity.

Patent GB-377809-A (GB)
Title: Improvements in or relating to the manufacture of thermoplastic materials or articles comprising a cellulose derivative
IPC: C08L1/12
Filed: 1931-07-15
Abstract: A method of producing a plastic composition consists in associating together a cellulose derivative and a resin to form a homogeneous mass, reducing this mass to a very fine powder and then mixing it with a plastifier and, if desired, a filler, such as silica flour, in the absence of volatile solvent, until a homogeneous mixture is obtained.  The mixture may then be worked on hot rolls or in a kneading machine to plastify the cellulose derivative or be used directly as a moulding powder.  The preliminary association of the cellulose derivative and the resin may be carried out by admixing the two in a heated state, or by adding a solution of the resin in a nonsolvent, such as benzene or alcohol, of the cellulose derivative thereto and drying.  The resin used may be natural such as acaroid, rosin, or copal or artificial preferably of the permanently thermoplastic type such as glycol phthalate, vinyl polymers, and sulphonamide resins derived from aromatic hydrocarbons containing a methylene group. An example of a suitable composition, in parts by weight, is red acaroid resin 15, cellulose acetate 15, plastifier 12, amyl stearate 0,5, filler 56, carbon black 1, dye 0,5.
