Title: A process for rendering textiles and ribbons, foils and the like which contain natural or regenerated cellulose, shrink-proof
Filed: 1938-09-01
Abstract: 518,872. Shrink-resisting treatments. HEBERLEIN & CO., AKT.-GES. Sept. 1, 1938, No. 25606. Convention date, Oct. 12, 1937. [Class 15 (ii)] Textiles, ribbons, foils, and the like containing natural or regenerated cellulose are treated with solutions of formaldehyde in concentrations of from 50 to 200 grams of 40 per cent. formaldehyde per litre in the presence of acid or acid yielding catalysts and after removal of excess liquid are heated to 90‹ C. to 160‹ C., the heating being continued until the material is proof against shrinkage but discontinued before it is substantially crease-proof or possesses any substantial resistance to swelling by strong swelling agents. Examples of catalysts which react acid under the conditions are aluminium thiocyanate, halides, or sulphate, ferric chloride, alum, acid salts of polybasic acids such as monosodium phosphate, ammonium chloride or thiocyanate, and acids which lie within the fibre-impairing limits such as malonic and succinic acids. In an example, a Vistra-muslin (the word "Vistra" being a Registered Trade Mark) is impregnated for 15 mins. with a solution of 200 gms. of commercial formalin and 40 ccs. of a 23 per cent. solution of aluminium thiocyanate per litre of impregnating liquid. The impregnated fabric is squeezed out and predried at 60‹ C., and then after-treated for 15 mins. at 125‹ C., washed, tentered and dried. The treated fabric shows no clearly recognisable crease-proof effect, and'is not resistant against 15 degreesBÚ caustic soda on 10 seconds immersion and drying, or against 54 degrees Be sulphuric acid on reacting therewith for 12 seconds. On a washing test, however, a contraction in length of only 0.7 per cent. and an increased in width of 0.9 per cent. were shown as compared with contractions in length and width of the original fabric under like conditions of 6.1 and 6.0 per centrespectively. Specifications 452,150 and 477,084 are referred to.

Abstract: 1384988 Radar-actuated tensioning device for vehicle safety belt DAIMLER-BENZ AG 30 May 1973 [3 June 1972] 25669/73 Heading A3V A restraining device, such as a safety belt 14, for an occupant of a vehicle is provided with an actuating device 8 for putting the restraining device under tension, the actuating device being triggered when risk of a collision of the vehicle is imminent by means of a signal emitted by a proximity-measuring device I operating on the radar principle. The proximity-measuring device comprises a transmitting element 2 and receiving element 3 connected to a signal comparison device 4 which measures the time between transmission of a signal and the reception thereof after reflection from an object with which there is risk of collision. When such risk is detected a pulse generator 6 opens a control valve 7 to allow a pressure medium from a pressure accumulator 10 to displace a piston 15 against the force of a spring 16 in a cylinder 11, thereby to tension the belt 14. The tightening of the belt is automatically stopped on attainment of a belt tension which is still just tolerabe to the wearer, and/or the valve 7 is controlled in dependence on the strength or frequency of pulses so that the belt is tightened e.g. with increasing speed. When the risk of collision recedes a pump 9 assists the spring 16 in restoring the original tension. The actuating device may be hydraulically or pneumatically operating or an electromagnetic or mechanical system such as a stressed spring may be used.

Title: Improvements in or relating to the preparation of compositions containing urea-formaldehyde condensation products
IPC: C08G12/12
Filed: 1936-09-28
Abstract: Reaction products of urea, thiourea and derivatives thereof with formaldehyde, which are still water-soluble, are dissolved or suspended in a primary or secondary monohydric alcoholic solvent and are heated in the presence of an acid catalyst and of an amount of formaldehyde sufficient to bring the total free and combined formaldehyde into excess of two molecular proportions to one of urea, the alcoholic solvent together with any water present or formed being simultaneously or subsequently distilled off and the heating being continued until the product is soluble in hydrocarbon solvents.  The reaction may be carried out in a vessel heated by a bath maintained between 120-140 DEG  C. and at atmospheric, or under increased or reduced pressure, according to the solvent.  The quantity of formaldehyde used depends upon the initial condensation product and upon the quantity and strength of acid employed.  Specified acids are hydrochloric, sulphuric, acetic, oxalic, lactic, phthalic and maleic. The alcoholic solvent, which may be added at once or in stages, preferably consists of an alcohol containing at least four carbon atoms and sparingly soluble in water, e.g. butyl alcohol; benzyl alcohol may be employed in conjunction with an alcohol of lower boiling point.  Natural and artificial resins, soluble in the alcoholic solvent, may be added at any suitable stage.  In a number of examples, dimethylol urea is worked up with paraformaldehyde in butyl alcohol.  Examples 12 and 13 include further additions, respectively, of ethylene glycol mono linoleate and linoleic diglyceride.  Examples 9-11 involve the use, respectively, of commercial amyl, octadecyl, and benzyl alcohols.  In example 5, urea and formalin, acidified with sodium acetate and boric acid, are first heated at 50 DEG  C., after which butyl alcohol and alcoholic hydrochloric acid are added and distillation effected first at 130 DEG  C., and then at 140 DEG  C.  Specification 442,054 is referred to.
