Title: Improvements in or relating to moulding processes
IPC: B29C39/24
Filed: 1929-09-12
Abstract: 319,689. Monge, H. J. A. Sept. 26, 1928, [Convention date]. Casting - apparatus; moulding resins - Hot viscous masses, e.g. condensation products, are fed into moulds through a lower orifice under the pressure of a heated liquid of lower specific gravity. For example, in producing rods or sticks, a number of tubular moulds are disposed vertically within a tank with their lower openings in proximity to the bottom of the tank; the appropriate quantity of casting material is then poured into the tank and, after heating the bottom of the tank an appropriate quantity of heated liquid of lower density, such as vaseline oil or other liquid hydrocarbon, is poured in causing the casting material to rise in the moulds to the desired height. To facilitate separation of the cast articles from excess material, liquid of greater density, e.g. mercury, may be poured into the tank after filling the moulds. According to a modification, the moulds are mounted in a suitable vessel adapted to receive the casting- material, the vessel and moulds being progressively lowered into a vat containing the liquid.

Class 25 A terminal for a flue outlet pipe and for like purposes comprises a tube open at one end for attachment to the flue and with a cap or closure at its other end, and with its wall formed with a plurality of lengthwise disposed equi-distantly spaced slots each occupying a predominating portion of the axial dimension of the tube, the: internal cross sectional area of the tube and the dimensions of the slots being so chosen that, in the use of the terminal with external air currents or wind pressure substantially normal to the axis of the tube the total face area of the slots exposed to negative pressure is approximately equal to the face area of the slots exposed to positive pressure plus the cross-sectional internal area of the tube. The terminal comprises tube 1 closed at the top by an inverted dish shaped cap 2 and formed at the bottom as a concentric cylindrical enlargement 4 forming a skirt for connection to a flue pipe.;A plurality. (twenty-four) of radial ;outlet slots 5 is formed in the tube wall each of the slots being of a width which is from one-third to one-half of the depth of the slot measured radially. When the terminal is made from a mouldable material such as asbestos cement the tube may be made thick enough to ensure adequate width for each slot in relation to its depth but when sheet metal is employed in order to avoid making the slots excessively narrow they may be formed by slitting the metal along the tube and turning inwardly or outwardly, preferably inwardly, parts of the metal lying laterally of the slits and welding to the radial webs thus formed narrow metal strips. In the terminal shown the total surface area of eighteen slots is substantially equal to the internal cross-sectional area of the terminal plus the total surface area of the other six slots. When the terminal is of a mouldable material the slots are so cut in the formed tube that lower draining surfaces are provided.

Title: Apparatus for measuring the degree of beating of pulp flowing through a conduit

Filed: 1971-06-16
Abstract: 1311072 Testing pulp KALLEREGULATORER AB 16 June 1971 [17 June 1970] 28254/71 Headings D2A and A8B In an apparatus for measuring the degree of heating of cellulose or mechanical pulp flowing through a pipe 3, a sample of pulp is introduced into test cylinder 7 over a strainer plate 20, a fluid pressure applied over the pulp and the rate of passage of water through the strainer plate measured. To fill the cylinder 7, piston 11 is caused to move upwardly from cylinder 9 and pushes disc 19 upwardly by means of hollow rod 18. After moving a short distance, disc 19 abuts strainer plate 20 mounted on hollow tube 21 which is a sliding fit in rod 18. Thereafter, disc 19, strainer plate 20 and plate 29 mounted on the upper end of tube 21 move upwardly and a cover plate 30 is also moved upwardly by plate 29 against springs 33 to place cylinder 7 in communication with conduit 3 Fig. 2 (not shown). Valve 17 is then opened to supply air under pressure to the space above plate 29, and piston 11 is caused to move downwardly, so that the moving parts take up the positions shown in Fig. 1, with the air pressure from conduit 15 being applied over the pulp. The water squeezed from the pulp passes to a vessel 39 where its volume or level after a predetermined time is measured. Water may be supplied through conduit 15 instead of air to pressurize the pulp Fig. 3 (not shown), the measurement then effectively being of the rate of diffusion of water through a fibre cake formed initially at the strainer disc. After a measurement rinse water, possibly mixed with compressed air, is supplied through conduit 27 and passes-out of conduit 37.

Title: Polymerisation process
Inventor: FANSHAWE RALPH SANTORRE
IPC: C08F36/00
Filed: 1964-07-09
Abstract: A cross-linked polymer of 2,4-pentadienoic acid is produced by heating the acid above its melting-point.  Up to 19 times its own weight of another ethylenically unsaturated material may be copolymerized with the acid, the said material being selected from the esters, salts and amide of 2,4-pentadienoic acid; alkenyl halides; alkenyl monocarboxylic acids; esters, amides and nitriles of the said alkenyl monocarboxylic acids; alkenyl esters of fatty acids; aralkenes and dienes.  Polymerization is carried out in bulk or in a liquid medium which may be a solvent or non-solvent for the acid and may be a copolymerizable monomer.  Additives such as dyes, pigments, stabilizers and fillers may be incorporated in the polymerizable mixture and moulded objects produced therefrom. In other embodiments the polymerizable mixture is applied to a substrate and polymerized to form a coating; or is used to bond two surfaces together; or is mixed with glass fibres and blended with a plastic, e.g. polymethyl methacrylate or polyvinyl chloride, during or after heating the mixture, in which case methyl methacrylate is a suitable comonomer with the 2,4-pentadienoic acid.  In examples the acid, alone or together with methyl acrylate' ethyl acrylate, methyl methacrylate, n-butyl methacrylate, styrene or vinyl acetate is polymerized between surfaces of metal, leather, wood, glass or synthetic polymer.

Title: Improvements in or relating to machines for rolling paste or dough
IPC: A21C1/08
Filed: 1935-05-25
Abstract: 457,382. Rolling dough. MORETON, W., Shandon, London Road, Leicester. May 25, 1935, No. 28403/36. Divided out of 457,334. [Class 87 (ii)] Relates to paste or dough rolling machines of the kind in which the dough is passed to and fro between reducing rollers, and consists in means for progressively reducing in an automatic manner the operative spacing of the reducing rollers between successive passages of the dough. The reducing rollers 1, 2 are connected by mangle gearing and the lower roller is provided with an operating handle 5, while the upper roller is mounted in verticallymovable bearings 3 controlled by weights 16 or springs tending to raise the roller 2. Each time the direction of rotation of the handle 5 is reversed, a shaft 21 carrying snail-form eccentrics is turned to depress the bearings 3 of the roller 2. In the position shown, if the handle 5 is rotated in an anticlockwise direction, a projection 37 will engage a spring-pressed lever 38 and thereby move a slide 34 to the right. A roller 40 on the slide acts on a cam-surface 41<a> of a spring-pressed lever 41 which is rocked, and through connections 42, 43 rocks a ratchet lever for turning the cam-shaft 21 and thereby reducing the space between the rollers 1, 2. When the direction of rotation of the handle 5 is reversed, the projection 37 acts on another spring-pressed lever 38 on the slide 34, whereby the slide is moved to the left into the position shown, and again rocks the lever 41 to operate the ratchet mechanism. A hand wheel may be provided on the shaft 21 for determining the initial setting of the rollers 1, 2. The snail cams on the shaft 21 are provided with low parts so that, after the minimum spacing of the rollers 1, 2 has been reached, the weights 16 raise the upper roller 2 clear of the dough. The mechanism may be used in conjunction with the arrangements described in Specification 457,334 for effecting the reversal of the paste carrying means and for ensuring that the means for carrying the paste from the reducing rollers travel at a greater rate than that of the means for feeding the paste to the rollers.
