Title: Improvements in or relating to the extraction of dust and fines from materials
IPC: B07B4/02
Filed: 1937-07-16
Abstract: 500,870. Pneumatic separating ; washing gases. NYBORG,T. G., and MINING ENGINEERING CO., Ltd. July 16, 1937, No. 19780. [Classes 23 and 117] [Also in Group XII] In the extraction of dust and fines from material such as coal, the material is traversed by a high velocity current of air or other gas so that dust and fines are taken into suspension, the dust &c. laden air is given a rotational movement to deposit the larger dust particles by centrifugal action and the air carrying the fine dust is given a vortical movement and is simultaneously sprayed by a liquid along the axis of the vortex to cause the fine particles to deposit as sludge. The air may be exhausted into the atmosphere or operate in a closed circuit. The apparatus described comprises a chamber 3, which may be provided with baffles over which the coal &c. falls from a feed hopper 2 to a discharge trough 5 which may form part of or lead to a coal washer. A fan 6, preferably of the centrifugal type, causes a high velocity air current to pass through the material in its passage through the chamber 3 and carry in suspension the dust and fine particles. The air is delivered with rotational movement into the annular space between an outer tube 8 and inner tube 9, with an intermediate baffle 10. A liquid spray 16 is mounted at the top of the tube 9. The larger particles deposited in the outer tube fall on to a collecting plate 12 and arc delivered by a weighted door 13, conduit 14 and conveyer 15. The air carrying the fine particles passes down the inner tube 9 with a whirling movement and the fine particles are caused to deposit as sludge by the liquid spray from the jet 16 and are delivered by the conduit 17, weighted door 18 and the conveyer 15. The cleaned air is returned to the chamber 3 by the passage 11.

Title: Amorphous linear copolyesters
IPC: B32B27/00
Filed: 1961-06-01
Abstract: An amorphous film, which may be readily heat-sealed to itself or laminated to another substrate (see Group VIII), is made from a copolyester of (a) terephthalic acid, (b) an alkylene glycol of formula HO(CH2)nOH, where n=2-10, and (c) a branched-chain glycol of formula HO-CH2-C(R)2-CH2-OH, where R is an alkyl group containing 1-4 carbon atoms, the alkylene terephthalate recurring units constituting from 20-75% of the recurring terephthalate units in the copolyester. The films may be made by extruding the copolyester through a plate die on to quench drum. In Example 15, the polyester and polyethylene terephthalate are extruded on to the same quench drum and the resulting film laminate stretched in two directions and heat set.  In Example 17, the copolyester is extruded through an annular die and the resulting tubing expanded with air which is sealed in the tubing between the die and the nip of a draw roll; the tubing is then drawn through a cooling zone where molecular orientation is effected by orientation and the film expanded to its final diameter.  Finally, the tube is flattened by passage through draw rolls and the film is split.  The copolyester may be made by (a) reacting terephthalic acid or an alkyl ester thereof with a mixture of the glycols to form a mixed ester which is thereafter polymerized, or (b) conducting two separate ester-forming reactions between terephthalic acid or an alkyl ester thereof and the alkylene glycol and terephthalic acid or an alkyl ester thereof and the branched-chain glycol, and thereafter mixing the two resulting esters and copolymerizing them.  The usual esterification or ester-interchange catalysts may be used. Examples describe the manufacture of copolyesters by reacting dimethyl terephthalate, ethylene glycol and either 2:2-dimethyl-1:3-propane diol or 2-methyl-2-ethyl-1:3-propane diol.  Specifications 578,079, 729,803, 731,023 and 773,778 are referred to.

Title: Process for improving cellulosic textile materials
IPC: D06M13/11
Filed: 1961-06-01
Abstract: Cellulosic textiles materials e.g. regenerated cellulose and cotton, are crease proofed and shrink proofed and may be fire-proofed by treating them with compounds or resin precondensates capable of being further condensed or hardened by the action of an acid or a substance yielding an acid and bringing about hardening on the material by the use as hardening agent of a polymer or co-polymer of vinyl-phosphoric acid and/or the monoesters, diesters, monoamides or diamides of such acid and/or a salt of such acid or of the corresponding monoesters or monoamides.  The compounds or resin precondensates may be the reaction products of urea, melamine, ethylene-urea or a triazinone with formaldehyde or ethers thereof, epoxy compounds, e.g. the reaction products of epichlorhydrin with polyhydric alcohols such as glycol, glycerine or pentaerythritol, compounds containing a plurality of ethyleneimine groups, e.g. trisaziridinyl phosphine oxide, polyaldehydes or polyacetals.  Suitable salts of the polyvinyl-phosphonic acid are the alkali and alkaline earth metal, amine and ammonium salts and suitable copolymers are copolymers of vinyl phosphonic acid or ester or amide or salt thereof and vinyl acetate or acrylic acid.  1-50% of hardening agent calculated on the weight of the compound or resin precondensate to be hardened may be used and hardening may be effected by heating to 90 DEG -160 DEG C. The treating composition may also contain other acids and acid yielding substances, e.g. formic, acetic, lactic and oxalic acids and salts thereof, ammonium chloride, ammonium nitrate, diammonium phosphate and zinc fluorborate, softeners, hydrophobizing agents, fungicidal or bactericidal substances, fillers and stiffening agents.

Title: Improvements relating to variable-area jet nozzles of turbojet engines
IPC: F02K1/12
Filed: 1959-06-10
Abstract: 871,265. Jet propulsion nozzles. GENERAL MOTORS CORPORATION. June 10, 1959 [June 25, 1958], No. 19857/59. Class 110 (3). The exhaust pipe of a turbo-jet engine is terminated by a variable cross - section convergentdivergent nozzle and cooling air is forced in by the ram pressure through apertures so as to flow over the external surfaces of the throat and exit and into the throat to flow over the inner surfaces of the exit flaps. As shown, the twenty-four throat flaps 28 and twenty-four exit flaps 37 are simultaneously rotatable about the hinges 41, 84 by the ring 33 which is positioned along the exhaust axis by the cylinders 34. To reduce drag, the fairing 22 is formed of flaps 38 pivoted at 127 and slidably coupled to 37 at 135. The ring 33 is connected to alternate flaps 28 by the arm 31 and cam 32 fixed to 33, and coupled also to alternate flaps 37 by rods 91. The slave flaps 28 are caused to move with the master flaps 28 by clips mounted in the slaves and engaging the adjacent master. The slave and master exit flaps 37 are moved together by a cam mounted on the carriage 89 and engaging with followers carried on each of the adjacent slave flaps 37. Movement of carriage downstream along track 88 by rod 91 thus rotates 37 about 84 to reduce the exit diameter and simultaneously operates the cam and follower mechanism to give the slave 37 flaps a similar displacement. Cooling is effected by air under ram pressure entering through apertures 63, 75, 141 in the fixed flange 39. Some passes between the fairing 22 and 37 and is discharged through annular gap 144 while the remainder flows through openings 142 to the outer surface of 28 which it leaves through gap 143 to form a layer over the inner surface of exit flaps 37. In an alternative form, not shown, the fairing flaps are positioned by one operating cylinder and the throat and exit flaps together by a second independent cylinder. The fairing flaps are coupled together, to produce variation of exit diameter, by a mechanism similar to that controlling the exit flaps in the first embodiment. Cooling is effected from ram air as in Fig. 3.
