Title: Process and apparatus for manufacturing blended yarns from  synthetic polymers
IPC: D01D5/08
Filed: 1971-04-19
Abstract: 1348923 Multicolour hetero yarns VICKERSZIMMER A G PLANUNG UND BAU VON INDUSTRIEANLAGEN 19 April 1971 [15 April 1970] 24530/71 Heading B5B [Also in Division D1] Blended, multicolour yarns comprising filaments of two or more fibre-forming polymers, preferably polyesters and polyamides, are prepared in a process which comprises melt extruding two or more polymers, one of which is dyed, simultaneously through spinnerets, each of which is associated with a single polymer, to form at least two groups of filaments which are solidified and guided in a single plane so that filaments of different colours alternate and lie next to one another and thereafter joining the groups of filaments into a multifilament yarn which is then wound up by conventional winding means. At least one of fibre-forming polymers may contain a delustrant and/or may exhibit higher thermal shrinkage than the other component polymers, when the multifilament yarns produced by the process combine not only filaments of different colours but also of varying lustre and/or, after suitable heat treatment may be yarns of high-bulk or loop yarns. Between formation of the yarn and wind-up the multifilament may be given a spin-finish, drawn and textured. In apparatus suitable for preparing the multicolour blended yarns two polymer streams are fed from separate tanks 1 and 2 to spinnerets 6 and 7 in spinning beam 5 and extruded as two separate groups 8 and 9 of filaments which are solidified and pass through a guide 10 in which filaments of group 8 alternate with those of group 9 (Fig. 2, not shown). The groups 8 and 9 are combined on roll 11 to form a multifilament and fed to draw rolls 13, 14 via roll 12 which applies a spin finish to the yarn. After drawing the multifilament passes through texturing zone 15 where it is optionally crimped and is then wound up on bobbin 16. Blended yarns of different counts useful in the preparation of fleece-covers, cut-pile carpets and boucle goods may be prepared by using spinnerets in which the orifices have different diameters, the colour effect of the blended yarn being further affected if the orifices have different cross-sectional shapes.

Title: Method of dehydrating gypsum
Inventor: RUEHLE RICHARD RALPH
IPC: C04B11/02
Filed: 1958-08-05
Abstract: In the dehydration of gypsum to the hemihydrate in a sealable indirectly heated vessel, the vessel is alternately sealed for at least three minutes and then vented, until the desired dehydration has occurred.  Venting is generally effected at 30 to 40 p.s.i.g. and temperatures at about 300 DEG F.; the vessel is preferably resealed before the temperature drops below 212 DEG F. and the product is finally dried by heating to 320 to 340 DEG F.  The apparatus employed is the same as that disclosed in Specifications 866,126, 897,923 and 897,925.  As shown in Figs. 1 and 2, a drum 7 is supported by and rotated with an axial pipe 21 which rests on rollers 5 carried by support 2.  Inside the drum the tube 21 carries a concertinalike arrangement of annular dished members 26 peripherally joined to form a series of chambers communicating with the interior of pipe 21 through perforations 25.  A gas burner 22 delivers a blast of hot combustion products into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26. The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the container, by means of pipes 30.  Tubes 8 are provided with exhaust passages 31 having a terminal elbow whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhaust 31 in contact with the exterior of the drum 7.  Gypsum is fed to the drum through removable closures such as 11 and the steam formed by dehydration is vented through valves 13.  As shown in Fig. 2 the valves 13 are operated by a lever 16 which abuts a valve-operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.

[Class 29] The evaporator 15 of a compression system is defrosted by hot gas supplied direct from the compressor 1, the gas being condensed in the evaporator during defrosting and the liquid passing to a heat storing element 5, 18 normally heated by the hot gases, where it is evaporated and flows back to the compressor. The defrosting may be automatically controlled by electric timing apparatus. In normal operation, the gas from the compressor 1 passes through a pipe 4 into a coil 8 immersed in a solution of alcohol or ethylene-glycol in an insulated vessel 5 and thence through a condenser 9, receiver 11 and expansion valve 13 to the evaporator 15, returning by pipe 17, tank 18 and pipe 3 to the compressor. When a solenoid valve 30 is opened by the timing mechanism the hot gases pass by pipe 25 coil 27 beneath a drip tray 47 and pipe 29 tothe evaporator. Condensed liquid refrigerant passes through pipe 17 to the hot tank 18 where it flashes into vapour and returns to the compressor. The coil 27 prevents freezing of the drip water. A pipe 51 of small bore returns any oil from the bottom of the tank 18 to the compressor.

Title: Film-forming organic materials
IPC: B29C48/08
Filed: 1949-09-30
Abstract: The tendency of certain organic, film-forming compositions to corrode metal processing apparatus is removed by adding 0.05 to 3 per cent, by weight of the film-forming material, of a hydroxy compound having a carbon to carbon triple bond.  Examples of such compounds are acetylene alcohols and hydroxyalkylation products thereof, e.g. propargylic alcohol, 1,4-butindiol, and their hydroxyethyl ethers and poly-hydroxyethylation products.  The corrosive constituent may be the film-forming material itself or another material such as ammonium nitrite, in the form of a mixture of sodium nitrite and an ammonium salt, used for expanding the composition into porous shapes.  The film-forming materials include polymers and interpolymers of vinyl chloride, vinylidene chloride, vinyl esters and acrylic esters; and cellulose esters, e.g. the acetate.  Plasticizers, e.g. dibutyl and dioctyl phthalate, may be included.

Title: Photographic emulsions
IPC: G03C1/053
Filed: 1945-10-04
Abstract: The preparation of interpolymers of acrylic or an a -substituted acrylic acid and an acrylic acid or a -substituted acrylic acid amide is described for use in photographic emulsions comprising a light-sensitive material dispersed in a thermal-reversible gel containing gelatine and the interpolymer. Terpolymers may be used by including acrylic acid esters or vinyl esters in the interpolymerization mixture, and alcohol groups may be introduced into the terpolymers prepared from vinyl esters by hydrolysing or partially hydrolysing the terpolymer formed. Preferably, the interpolymer components contain polar substituents, specified are hydroxyl, amino, amide, formyl, carboxyl and nitrile groups.  The interpolymerization is preferably carried out in aqueous emulsion at a pH of 4-9 in the presence of an oxidizing catalyst.  Products containing carboxyl groups may be partially esterified with ethylene glycol or glycerol.  The gel may be hardened by addition of aluminium and chromium ions and its permeability to water increased by addition of polyvinyl alcohol.  Examples are given of the interpolymerization of methacrylic acid and methacrylamide with or without the addition of methyl acrylate.  Specification 626,626 is referred to.
