Title: False-twisting apparatus for producing crimped filament yarns
IPC: D02G1/08
Filed: 1976-06-23
Abstract: A method and an apparatus for producing crimped filament yarns, said apparatus comprising at least one first twister member and at least one second twister member, each of said twister members having a work surface made of a synthetic rubber having a relatively small friction coefficient therebetween. These twister members are arranged so that their work surfaces cross each other at a selectable angle in contact relationship to provide at least one crossing zone for nipping therebetween at least one thermoplastic filament yarn which is fed to twist this filament yarn between the contacting work surfaces successively and at the same time to urge this filament to discharge from this crossing zone successively as the twister members are driven. This method and apparatus allow filament yarns to be imparted desired false-twisting effect, practically without being damaged and without causing uneven twists, at a high operation rate of 800 - 1000 meters per minute.

Filed: 1924-07-17
Abstract: 246,078. Dehn, F. B., (Rudd, Manufacturing Co., E. G.). July 17, 1924. Latches, swinging, for automobile doors, are pivoted on a base plate and operated by a follower through a slide pivoted to the latch and sliding on the base plate, the slide being out of contact with the base plate except for a short portion of its length. The latch 17 is pivoted at 16 on the base plate 10 and is operated by a slide 19 having a cranked part 24 pivoted at 26 to the latch. The slide is cut away at 20 forming a hole through which passes the spindle 34 carrying the follower-boss 38, arms 39 on which engage shoulders 40 on the slide to move it to withdraw the latch. A spring 28 keeps the follower spindle in normal position and a spring 27 acts on the slide to keep the latch shot. The slide is guided by a lug 21 sliding in a slot 22 in the base plate. The thickened part 23 of the slide is the only part of it which is in contact with the base plate. The upper face of the part 23 slides under the bridge-piece 30 on which rests the spacing member 32 attached at its other end to the outside panel of the door.

Filed: 1965-06-22
Abstract: 1,160,223. Thermographic transfer processes. GEVAERT-AGFA N. V. June 22, 1966 [June 22, 1965], No.26468/65. Heading G2C. A thermographic transfer process i.e. which a heat-sensitive transfer sheet is imagewise heated to remove or convert some of the heatsensitive material therein and then contacting with a receptor sheet containing a reactant which reacts with the heat-sensitive material and transferring the remaining reactant by means of heat or a liquid produce a colour charge on the receptor sheet. The transfer sheet preferably contains light-absorbing, sheet-generating substances so that on imagewise flash-exposure to visible light the sheet becomes heated imagewise. Specified heat-sensitive material with their reactants are: (a) compounds splitting off sulphur e.g. dithioexamide, thioacetamide and p-phenylenedithiourea (with organic salts of copper, silver, lead or nickel) (b) organic acid (with pH indicators), (c) benzoylperoxide or tetrachloroquinone (with organic compounds which change colour on oxidation (d) azo couplers (with diazomium salts); (e) phenyl-pyrazolidinones (with silver and gold salts, triazdium and tetrazolium compounds (f) 8-hydroxy- 1, 2, 3, 4-tetrahydroquinoline or phenols and naptholm), (with organic salts of iron, copper, silver or cobalt; (g) N, N-dimethylbenzamide or N-methylacetamide (with 5-bromo-aminothiazoles; (h) nitroso compounds (with aromatic hydroxy corresponds; (i) triazenes (with azo couplers); (j) aromatic amines and hydroxyamines (with silver, mercury or cadmium salts, nitroso or diazonium compounds) (k) aromatic nitro compounds (with iron salts, and (m) compounds which release amines on heating (with diazonium salt and a coupler or pH indicators). In the examples, the heat, sensitive material and carbon black or silver are dispersed in a binder and applied to a support. The transfer material is either directly or reflex flash-exposed using a xenon gas discharge lamp to evaporate the heat-sensitive material in the areas corresponding to the background of the original. The transfer material is contacted with the receptor sheet containing the reactant and heated to produce a positive coloured image on the receptor sheet. Alternatively the exposed transfer material may be moistened with water and contacted with a receptor sheet to produce a coloured image on the receptor sheet.

Title: Improvements in the preparation of cement raw materials
IPC: B03D1/02
Filed: 1938-09-12
Abstract: 515,609. Concentrating ores ; cements. SMIDTH & CO. AKTIESELSKABET, F. L. Sept. 12, 1938, No. 26612. Convention date, Sept. 10, 1937. Drawings to Specification. [Class 82 (ii)] [Also in Group V] To render them more suitable for use in cement manufacture, calcium carbonate ores such as argillaceous limestones, chalks, and marls, are subjected to froth flotation with a collecting agent which will effect a concentration of siliceous minerals in the froth. A suitable collecting agent is one which gives in solution a positively charged surface-active ion containing an aliphatic hydrocarbon radical of at least 8 carbon atoms, e.g., a quaternary ammonium compound, preferably one with a hydrocarbon group of 12-18 carbon atoms or a salt of an aliphatic amine such as dodecylamine hydrochloride or a mixture of the hydrochlorides of the higher amines corresponding to the fatty acids of coconut oil. The reagent is used in conjunction with a frother, e.g., cresylic acid or a mixture of alcohols obtained, with methanol, from the catalytic hydrogenation of carbon oxides. The whole or part of the ore from which it is desired to remove some of the siliceous minerals may be subjected to the froth flotation, for example, the ore may be ground and classified and either the coarse, the intermediates, or the fines treated by flotation. The flotation tailings, which are enriched in calcite, may then be combined in any desired proportions with the untreated portions, additional correctives such as free silica being added if required to give a suitable mixture for the cement. When treating a carbonaceous calcite ore, the carbon may either be removed by a preliminary flotation or it may be depressed during the flotation of the siliceous minerals by the addition of a lignin sulphonate, as described in Specification 515,592, lignin sulphonates, with or without alkali, may also be used, as described in Specification 515,601, to deflocculate the pulp before the. preliminary classification or prior to flotation the siliceous concentrate may be cleaned without further addition of reagents, the cleaner tailings being normally returned with or without regrinding, to the conditioning step preceding the rougher flotation. The volume of air admitted to the flotation cells is preferably below normal. The amount of collecting agent which is preferably introduced by stages, is controlled according to the nature of the minerals it is desired to remove, the agents having preferential affinity for micas, feldspars, silica, iron oxides, and calcite, in that order. Flow sheets are given illustrating the treatment of an argillaceous limestone to reduce the quantity of alumina and combined silica ; the various products obtained, which may include flotation concentrates, rougher tailings, cleaner tailings, and unticated ore, being combined as desired to produce the final cement raw material. Specification 463,261 and U.S.A. Specification 2,132,902 also are referred to.
