Abstract: In drawing glass filaments from a crucible 1 including at least one row of extrusion nipples 2 having an aperture through which molten glass flows to form an inverted cone 17 whose apex becomes the filament, the filaments then being collected together and drawn out to form a thread (6), the extrusion nipples 2 are cooled by cooling fluid through at least one pair of pipes 9, 10; 9a, 10a for cooling the or each row, the pipes being substantially parallel to each other and to the row of nipples 2, the fluid <PICT:1079099/C1/1> <PICT:1079099/C1/2> flowing through one pipe 9, 9c in one direction and through the other pipe 10, 10a in the other direction whereby the cores 17 of molten glass are kept at substantially the same temperature. Each pair of flattened pipes 9, 10 as shown may be welded together, or formed from stamped out sheet metal and are connected at one end 12, the other ends leading respectively into pipes 14, 15 extending across one end of the crucible 1 for connection to sources of, e.g. distilled water.

IPC: A63H3/46
Filed: 1928-07-03
Abstract: 314,677. Harris & Sheldon, Ltd., and Richards, R. G. July 3, 1928. Lay figures.-In a bayonet joint connection, particularly for detachable parts of a lay-figure, accidental separation of the parts is prevented by a resilient tongue or blade on one part which is brought into engagement with a bearing plate &c. on the other part by relative rotation of the parts. In the construction shown a blade spring 23, tangentially secured to the spigot member 2, is adapted to frictionally engage a bearing plate 21, secured in a longitudinal slot 20 in the socket member 1, when the spigot member is rotated to bring a stud 5 thereon behind a shoulder formed by a recess 4 leading from a longitudinal groove 3 through which the stud 5 is inserted in the usual manner of a bayonet joint. In a modification a blade spring is secured in a longitudinal groove in the socket member and is engaged by a plate secured to the spigot when the spigot is rotated to lock the parts, the arrangement being such that the spring is depressed when the parts are turned to effect their disengagement.

Title: Improvements in or relating to grinding, crushing, pulverising and like mills
IPC: B02C13/13
Filed: 1934-06-29
Abstract: 425,271. Impact pulverizers; separators. LESTRINGUES, L. L., 239<bis>, Rue Lafayette, Paris. June 29, 1934, No. 19306. Convention date, June 29, 1933. [Classes 59 and 117] In a beater mill provided with air vanes on one or both sides of the wheel carrying the beaters, the air vanes supply the whole of the air for carrying off the ground products and do not come in contact with ground material. The material to be ground is fed to the mill by an airtight feeding device. As shown in Figs. 1, 2, the pulverizer comprises one or more discs 8 provided with pivoted hammers, and on each side of the discs a fan is provided, the blades of which are adjustable. Air or hot gas supplied through inlet 13 is led to the fans through ducts 14 and is discharged with pulverized material through duct 19 to a classifier 28 where it impinges on a pivoted deflector 20 which diverts part of the gases across the classifier in the direction of the outlet 23 and the remaining part over the deflector to an adjustable plate 21. The outlet 23 is provided with adjustable flaps 25 pivoted to a telescopic tube 22. The coarse material separated out is conveyed by a screw 30 and pivoted flap 39 to the pulverizing chamber. Pulverized material from the outlet 23 may supply burners and if low grade fuel is being pulverized means is provided to start up with high grade fuel. This fuel is inserted through a door 34 into an intermediate chamber 33 of the hopper, the inlet from the hopper being closed by a door 32. A pivoted door 37, from the intermediate chamber 33, permits the fuel to pass to a mill feeder 4. After the burners have started, the door 34 is closed and the door 32 opened so that low grade fuel is fed to the mill. The pivoted door 37 in the closed position may actuate an alarm or stop the mill motor. The disc 8, Fig. 4, may be secured to a boss 81 mounted on a sleeve 43 or boss integral with the side wall by ball &c. bearings 42. The sleeve is secured to the side wall by a nut and the driving shaft 6 passes through the sleeve and is secured to a flange 8<111> bolted to the hub. Sleeves 50, 51, secured to the casing and door 2, partially enclose the hub and cause cooling air, entering through holes 52, 53, to circulate around the hub bearing. In a modification, the bearing is mounted on a stub axle fixed to the door whilst the cap 49 is driven by the motor through a sleeve.

Title: Stabilization of alumina by contact of hydrous alumina with carbon dioxide
Inventor: KEITH KARL DONALD
IPC: C01F7/34
Filed: 1959-06-08
Abstract: Hydrous alumina comprising alumina monohydrate, obtained by precipitation from an aqueous solution of an aluminium compound, is stabilized, and peptization is prevented, by contacting an aqueous suspension of the alumina with carbon dioxide, or by washing the alumina with water containing carbon dioxide.  The stabilization prevents the alumina monohydrate being converted to alumina trihydrate.  The hydrous alumina may contain 65 to 95% by weight of alumina trihydrate.  In examples aluminium chloride solution is reacted with ammonia solution to precipitate alumina, which is washed with water containing carbon dioxide, slurried in water and the water saturated with carbon dioxide; a catalyst is prepared by impregnating alumina hydrate with H2PtCl6, reacting it with hydrogen sulphide, and forming it into pellets, which are calcined.  Specification 832,200 is referred to.
