Title: Apparatus for the continuous mixing of solid substances with thermoplastic binding agents
IPC: B01F7/04
Filed: 1959-08-24
Abstract: 854,273. Mixing. SCHREINER, H. Aug. 24. 1959 [Aug. 22, 1958], No. 28867/59. Class 86 Apparatus for the continuous mixing of solid materials with thermoplastic binding agents, e.g. stones, gravel or sand with bitumin for road surfaces, or fine coal and comminuted ores and binders for briquetting, comprises a trough 1 having a dry mixing zone A followed by a zone B for mixing with the liquefied binder and then by a discharge zone C, two parallel groups of co-axial shafts 4.7, 11 passing through all the zones and carrying mixing and conveying members 6, 9, 12, the individual shaft members of each group of shafts being rotatable as regards speed and direction independently of any of the other shaft members. The independent drives to the shafts 4, 7, 11 are through toothed wheels 5, 8, 13. The dry solid materials are introduced at 2. mixed by members 12 and passed to the zone B where, in the arrangement shown, the members 9 rotate oppositely to throw the materials upwards to be sprayed at 15 by hot binder. When a briquetting mixture is being made. steam or water is fed into the zone B. The adjustability of the rotational speeds permits the apparatus to be used for various materials and proportions thereof

Title: Apparatus for the hot-stretching of filaments
Inventor: BEAUMONT ALBERT GORDON
IPC: D01D10/04
Filed: 1962-07-27
Abstract: 1,043,236. Hot-stretching filaments. COURTAULDS Ltd. July 26, 1963 [July 27, 1962], No. 28898/62. Heading B5B. Apparatus for hot-stretching artificial filaments comprises a steam-jacketed metal tube and one or more orifices in the tube wall, located within the steam jacket and connecting the interior of the tube with the jacket space. In one embodiment (not shown), a tube 7, through which a filament bundle passes while being stretched, is surrounded by a steam jacket 10 having steam inlet 11 and combined steam outlet and trap 12. Steam contacts the filaments through spaced orifices 9 in the wall of tube 7. The ends of tube 7 are constricted by coaxial narrow tubes 8 of a diameter 3-10 times that of the filament bundle. In a further embodiment (not shown), the entire length of the tube 7 is of a diameter 3-10 times the diameter of the filament bundle. Alternatively, the ends of the tube may be constricted by movable throttle plates. In operation, a bundle of filaments, e.g. acrylic polymers or cellulose acetate, is drawn through the tube 7 from bottom to top whilst undergoing stretch. Steam supplied to the jacket 10 enters orifices 9 and contacts the filaments. Since the only surface within the tube at a lower temperature than the steam is that of the filaments, loss of heat by condensation of the steam on the walls of the tube is avoided.

Class 46 A replaceable filter unit comprises a pleated filter body of resin-impregnated paper arranged in tubular form and with the pleats extending substantially radially, end discs of resin-impregnated paper closing off opposite ends of the body, the discs being bonded, by a thermosetting resin adhesive similar to the resin impregnating the filter body, to opposite end edges of the pleats, and having turned-down rims bonded by thermosetting resin adhesive to folds of the pleats. Paper impregnated with phenol formaldehyde resin solution is formed into a tubular body with pleats 12, Fig. 2, extending radially and surrounded by a perforated cover 16. An upper end disc 18 and a lower 19 (not shown) each having a central hole of smaller diameter than the hole 13 extending through the body are coated on one side with a phenol formaldehyde resin cement layer 22. The upper and lower end edges of the pleats 12 are also coated with the same cement and the discs then applied thereto with heat and pressure. Pressure is simultaneously applied to the outer edges 26 of the discs (which extend beyond the periphery of the body) and to the inner edges 24 to turn them down over and secure them to the pleat folds 17 and 15 respectively as shown in Fig. 2. The hole 13 has within it a helical coil 14 (not shown) extending from top to bottom of the unit between the inner rims of the discs against which coil bear the inner longitudinal folds 15 of the pleats.
