Patent GB-551065-A (GB)
Title: Improvements in milling cutters and the like tools and in chucks or holders therefor
IPC: B23B31/20
Filed: 1941-12-30
Abstract: 551,065. Chucks. CLARKSON, F. H. Dec. 30, 1941, Nos. 16758/41 and 1568/42. [Class 83 (iii)] In mounting tools in chucks of the frictionalgrip split-collet type, any rotation of the tool relatively to the collet or chuck body operates to produce axial pressure on the collet to increase the grip on the tool and to counteract any tendency towards axial outward movement of the tool. In Fig. 1 the collet 4 is caused to grip the fluted end-mill 14 by the conical surface 5 of a ring 7 screwing on the body 2. The end of the tool shank is screwed at 10 and engages in a screwed collar 11 held against rotation on the body by a pin 12. If the tool tends to slip in the collet the collar 10 is forced downwardly on to the top of the collet thereby increasing the grip produced by the conical surface 5. At the same time the tool is forced axially inwards thus resisting any tendency of the flutes to cause the tool to be drawn out of the collet. In a modification the screw threads are formed in the collet itself which is held against rotation in the body by the pin 12. In another modification, Fig. 5, the screw-threads 15 engaging the screwed collar are formed on a separate member having a tang connection 16 with the tool shank. In another modification, Fig. 6, the screwed end 10 of the tool shank screws into a tapped hole 18 in the body and any slipping of the tool causes a collar 19 to force the collet inwards to increase the grip produced by the conical surface 5a of the body. In a further modification, Fig. 9, a stud 21 having right and left hand threads separated by a collar 23 has one thread screwing in the body and the other in the tool shank. If the tool shank slips relatively to the chuck body the collar 23 forces the collet outwardly to increase the grip. In a modification of the form shown in Fig. 6 a shoulder between the thread 10 and the shank engages a necked part of the collet to move the latter into the body portion. In a modification of this latter arrangement a stud 28, Fig. 11, screws into the body and into the tool shank and a shoulder 24 moves the collet inwardly if slipping occurs.

IPC: C08F2/00
Filed: 1972-04-12
Abstract: 1364353 Film-forming copolymer dispersions COOK PAINT & VARNISH CO 12 April 1972 [16 Aug 1971] 16882/72 Headings C3P and C3R Film-forming copolymer dispersions are prepared by copolymerizing at least two ethylenically unsaturated monomers, each of which is free from hydroxyl and carboxyl groups, in a liquid, aliphatic or cycloaliphatic saturated hydrocarbon having dissolved therein an alkylated amine-aldehyde condensate. It is stated that the copolymer formed is cross-linked with the condensate, thereby forming a stable dispersion. The amount of condensate is generally from 5-50%, and the amount of monomers 95-50%, of the total weight of condensate and monomers. Copolymerization is advantageously carried out by gradual addition of the monomers to a heated condensate solution and in the presence of an initiator such as azobis-isobutyronitrile, lauroyl peroxide, benzoyl peroxide or a hydroperoxide. Suitable monomers include alkyl acrylates and methacrylates, glycidyl methacrylate, styrene, α-methylstyrene and acrylonitrile. The condensate is preferably a melamineformaldehyde condensate etherified with an alcohol such as butanol or lauryl alcohol. The liquid hydrocarbon may optionally include a minor amount of an alkanol, e.g. butanol or lauryl alcohol, or 2-ethoxyethyl acetate. The compositions are useful for coating. In examples coatings are applied on metal and glass substrates.

Title: Method of construction of the masonry of industrial furnaces, particularly siemens-martin furnaces
IPC: C04B35/00
Filed: 1933-06-16
Abstract: 405,527. Furnace walls and roofs. OTTO & CO., GES. DR. C., 9, Christstrasse, Bochum, Germany. June 16,1933, No. 17233. Convention date, Jan. 14. [Class 51 (ii).] The masonry of industrial furnaces, particularly arches of Siemens-Martin furnaces, is constructed of bricks or blocks cemented together by mortar which, while having a chemical composition similar to that of the bricks, has a greater resistance to heat than either the bricks themselves or mortar having the same composition as the bricks. In the case of bricks consisting essentially of quartzite, the mortar is made from pure quartz sand, while with silica bricks, the mortar is made from the same raw material as the bricks with all softening constituents, e.g. alumina, removed except lime which serves for binding. A suitable composition for use with silica bricks is 30 parts of sand between 0.2 and 0.3 m.m. mesh, 70 parts of pulverulent quartz below 0.06 m.m. mesh, 4 parts of lime, and one-half part of sulphite cellulose waste liquor. The mortar joints have a minimum thickness of 3 m.m. and are preferably relatively thick, e.g. 10 m.m.
