Title: Manufacture of resinous materials
IPC: C08G12/04
Filed: 1940-07-12
Abstract: 544,477. Lubricating compositions. DU PONT DE NEMOURS & CO., E. I., JACOBSON, R. A.. and MIGHTON, C. J. July 12, 1940, No. 11622. [Class 91] [Also in Groups IV and VIII] Resinous materials are obtained by condensing with formaldehyde a symmetrical nitrile of the general formula NCCXX<SP>1</SP>NHRNHCXX<SP>1</SP>CN. in which X and X' are alkyl radicals or hydrogen and'R is a polymethylene chain which, if of an even number of carbon atoms, may be centrally divided by -NH- or -N(CXX<SP>1</SP>CN)-. The products may be used as corrosion and sludge inhibitors for lubricating oils. Their properties may be modified by varying the molar ratio of formaldehyde and by conducting the re-action in the presence of other materials capable of re-acting with formaldehyde, e.g. phenols, amines, ureas, proteins, guanidine, or carboxylic or sulphonic acid amides. Examples are given of the preparation of resins from the following nitriles-1:6-di (α-cyanoisopropylamino)hexane, 1:10-di (a-cyanoisopropylamino)decane, 1:6-di- (cyanomethylamino) hexane, N-di(6-α-cyanoisopropylaminohexyl)-α-cyanoisopropylamine, 1 : 4- di (a-cyanoisopropylamino)butane, di-(2-α-cyanoisopropylaminoethyl)amine, N-di (2-α-cyanoisopropylaminoethyl)-α-cyanoisopropylamine, 1:2- di (α-cyanoisopropylamino) ethane and 1 : 6-di (α- cyano-α-ethylethylamino)hexane. Further examples of suitable nitriles are given.

Abstract: 1414044 Process and fibrous compositions therefor TAC CONSTRUCTION MATERIALS Ltd 25 Feb 1974 [9 March 1973] 11632/73 Addition 1148685 Heading C3N A process for coating a surface by spraying a mixture of fibre, a powder binder and water on to the surface is characterized in that the fibre is all mineral wool predominantly in the form of tufts, the binder is an "hydraulic binder" (not being a high-alumina cement) and the spray includes a non-mineral oil, i.e. vegetable oil or animal/fish oil. The expression "hydraulic binder" is defined as meaning both binders capable of setting by chemical reaction with water and inorganic binders capable of setting by purely mechanical means, i.e. by elimination of water on drying. The binder may be Portland cement including mixtures thereof with pulverized fuel ash, super-sulphated cement, magnesium oxychloride, magnesium oxysulphate, hydraulic lime, gypsum, clay, sodium silicate or potassium silicate. The composition to be sprayed may also contain a surface active agent, a cellulose ether or a fire-retardant compound, e.g. an organic phosphate.

Title: Improvements in or relating to hair driers
IPC: A45D20/22
Filed: 1953-04-27
Abstract: 748,606. Hair dryers. LECLABART, J., and HILTENBRAND, C. April 27, 1953 [April 30, 1952], No. 11633/53. Class 81(2). A hair drying machine comprises a helmet having a large number of small perforations through which jets of heated air pass from a motor driven impeller which is mounted together with an air-heating device within the main casing of the machine and in the vicinity of the helmet, the impeller being provided with an intake manifold formed with spiral-shaped passages. The helmet comprises two perforated walls 1, 3, the outer wall being secured at its lower edge to a partition 8 the upper edge of which supports a casing containing heating elements 18, a stator 19a and fans 19 which are driven by an electric motor 23. An annular space 12 outside the partition 8 and the casing is bounded by an outer casing 10 of the machine. The fans 19 draw air through holes 30 in the top of the machine from the apex of the helmet and from the annular space 12, through a mainfold 20 having spiral vanes and thence through the fans 19 and stator 19a so that it is forced over heating elements 18 and through holes 37 to a space 36 between the cylindrical partition 8 and the helmet. The air then passes through the helmet to the hair to be dried. Air is withdrawn from the lower part of the helmet through holes 2a which communicate with the annular space 12 so that the air may be recirculated. Both air drawn into the apparatus and recirculated air pass through a filter 25. The machine is mounted on a support 41, Fig. 4, and may be tilted by a lever 35 which has a handle 42 and passes through sleeve 40 attached to the casing 10. In a modification, Fig. 4, the annular space 12 and filter 25 are omitted, only one fan 45 is provided and the lower edge of the perforated helmet which has only one wall 1 is provided with an inwardly extending channel 39 which has perforations 2b, 2c on its upper side at the front of the helmet and on its lower side at the rear of the helmet so that air leaving the helmet is blown away from the face but on the nape of the neck. In another construction, Fig. 11 (not shown) air for recirculation is withdrawn by fans only through the apex of the helmet. In a further construction, Fig. 12 (not shown) air is recirculated after being withdrawn from the lower edge of the helmet through ducts located outside the front and back of the outer casing 10. In the last two constructions, Figs. 11 and 12 (not shown), the helmet, which is single-walled, is of transparent synthetic material and is integral with an outer part of the casing.

Title: Improvements in and relating to the stretching of synthetic filaments and filamentary yarns
IPC: D01F6/60
Filed: 1940-07-15
Abstract: 543,466. Stretching synthetic filaments. DU PONT DE NEMOURS & CO., E. I. July 15, 1940, No. 11711. Convention date, July 14, 1939. [Classes 120 (ii) and 120 (iii)] [Also in Group IV] Synthetic yarns and filaments, e.g. of a synthetic linear polyamide, which are capable of being elongated at least 150 per cent. of their original length are permanently and uniformly elongated by cold drawing or stretching the yarn or filament in contact with the surface of a non - rotatable snubbing pin around which the yarn or filament is wrapped at least one complete turn and on which the draw point is located while restricting the movement of the draw point on the surface so as to produce a uniformly drawn yarn or filament; the movement of the draw point is preferably restricted to a zone not greater than 2 inch along the path of travel of the yarn or filament. As shown the yarn is fed by a roller 21 to a drawing roller 27 the yarn being led around the rollers and separating rollers 23, 25 several times to prevent slipping of the yarn, the shifting of the draw point being prevented by and localised on the non-rotatable snubbing pin 24 about which the yarn is passed one or several turns so that the tension developed in the yarn at the pin will preferably be at least half of the tension required in the drawing operation; the drawing zone may be given a sustained shift by giving the pin a rectilinear circular or elliprical motion, the speed of the pin not exceeding 2 per cent. of the linear speed of the undrawn yarn. The pin is preferably made of agate but other smooth materials or alloys may be used and the diameter should not greatly exceed 2 inch. The rollers 21, 27 may be of the same diameter driven at different speeds or they may be of different diameter to give the different peripheral speeds necessary to give the proper drawing rates and the rollers may be arranged on the same shaft. Specifications 461,236 and 461,237, [both in Group IV] and U.S.A. Specification 2,071,250 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use of tension devices e.g. convex sheets or plates, in place of the snubbing pins and the application to staple length filaments and yarns. This subject-matter does not appear in the Specification as accepted.

The blades 2 are connected to a plate 3 formed with apertures 5 to prevent heat accumulation and also to a sleeve 4 joined to the plate 3. The sleeve 4 contains a heating element (not shown) in the bore 6 thereof. The surfaces 7 comprise wedge-shaped extensions of increased height. A U-shape frame is pivotally mounted on the die 1 under the action of compression springs 9. Screw-threaded bolts 10 limit the pivoting movement of the frame 8 in which cooling apertures 11 are provided. In use, an article G is pushed with a wrapper E through a folding tube 12 so that the wrapper E is folded to U-shape around the article. A pusher 13 folds down a first flap and the frame 8 folds down a second flap. As the pusher 13 retracts, the die 1 moves upwardly against the springs 9 and contacts and seals the wrapper E. After sealing, the die 1 is withdrawn, firstly, in a direction opposite to the feed direction of the articles G and then transversely to this direction. To prevent the wrapper E adhering to the frame 8, the latter is covered with a strip of polytetrafluoroethylene or of glass impregnated with polytetrafluoroethylene. Preferably, when the sheets to be sealed have been stretched, the lengthwise direction of each blade 2 extends in the direction in which the sheets have been stretched.
