IPC: D06M13/425
Filed: 1972-03-20
Abstract: 1372445 Durable press garment COTTON INCORPORATED 20 March 1972 13001/72 Heading DIP A cellulosic fibre-containing garment has wrinkle resistance, and crease and overall shape retention i.e. durable press properties imparted to it by a process comprising (a) pressing the garment to impart at least one crease to it and remove wrinkles from it, and supporting the garment in its pressed condition (b) impregnating the supported garment while maintaining its pressed condition, with a liquid impregnant containing heat curable constituents to give the garment wrinkle resistance, crease retention and overall shape retention properties upon subsequent curing as in step (d), (c) drying the impregnated garment while supporting it in its pressed condition without curing the impregnant, and (d) curing the impregnant by heating the impregnated garment to a temperature of 150‹-350‹F while supporting it in its pressed condition for a time sufficient to give the garment the above mentioned properties. The garment may be made from a knit, woven or non-woven fabric and may comprise cotton, viscose or cuprammonium, rayon, linen, and hemp or blends of these with each other or with wool, polyamides, polyesters, acrylics, polyolefins, p.v.c., polyvinylidene chloride, p.v.a. and cellulose acetate. The blends preferably contain at least 15% cellulosic fibre. The impregnating liquid exemplified is aqueous dihydroxy dimethylol ethylene urea containing a zinc nitrate hexahydrate catalyst and a non ionic surfactant, optionally together with a polyethylene emulsion as a softening agent. Other suitable conventional agents e.g. formaldehyde urea or melamine formaldehyde precondensates, triazones, polyacetals, epoxides, sulphones, carbamates and trisazoidinyl phosphine oxide, which also imparts flame resistance may be used. The impregnant may be applied by spraying the garment while supported on e.g. a clothes hanger, or by spraying, pouring or spongeing while the garment is supported on a flat surface. The drying of the garment is preferably carried out at room temperatures (20- 30‹C), pressures and humidities, until the fabric moisture content is below 15% and is preferably in the range 3-8% on the weight of the fabric. The curing step may be effected by placing the garments in a heating chamber. Between steps (c) and (d) the garment may be re-pressed with an iron having a temperature of 150-250‹F (65-120‹C) to improve the definition of the creases and eliminate wrinkles, the ironing time being such as to avoid curing the agent, e.g. less than 10 seconds.

Abstract: 1,220,998. Free-flowing washing powders. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. 19 March, 1968 [25 March, 1967], No. 13176/68. Heading C5D. A process for the production of a free-flowing washing powder mixture comprises (a) spraying into a free-fall zone an active-oxygen compound (e.g. alkali metal perborate) which can be fused in its own water of crystallization, the compound being sprayed in the form of a melt and the melt optionally containing additional water over and above the water of crystallization, and (b) blowing into the resultant spray cone a solution, suspension or powder containing washactive substances (i.e. surfactants), washing auxiliaries (i.e. substances which, although not surfactants, take part in or assist the washing action, for example silicates, polyphosphates, soda and cellulose glycolates) and optionally other additives. A granulate is removed from the end of the free-fall zone and may subsequently be dried. According to a modification of the process, all or part of the wash-active substances are mixed with the melt of activeoxygen compound prior to spraying. In the case of alkali metal perborate melts, 0À5-5% by weight (based on the perborate) of watersoluble compounds of magnesium, cadmium or zinc (e.g. magnesium chloride) may be added as stabilizer and the perborate melt may have been formed by reaction between metaborate and hydrogen peroxide. In examples, the preparation of washing powders containing such ingredients as sodium perborate, sodium silicate, sodium sulphate, sodium pyrophosphate, sodium tripolyphosphate and alkyl sulphate or alkyl benzene sulphonate surfactants is described.

IPC: F42B22/10
Abstract: 131,927. Seng, J. A. June 13, 1916. Mines, marine. - Relates to mines provided with a watertight chamber containing a soluble plug to which water is admitted through a valve for releasing the anchoring-mechanism or the firing- device after a given time, and consists mainly in the provision of means for preventing the opening of the valve if the soluble plug is prematurely removed. In the form shown in Fig. 1, the pawl b, which normally locks the mooring-drum a, is pulled by a spring h when a pin i is dissolved by water admitted into the water-tight anchor d by a cock e, which ie opened when the mine is laid. If the pin i is accidentally dissolved or broken before the mine is laid, the pawl b enters notches in a stop k fixed to the anchor and in an arm j attached to the cock e, thus preventing the opening of the cock. In a modification shown in Fig. 2, the pawl b is pushed by the stem o of a spring piston m when a pin p holding this is dissolved by water admitted into the water-tight piston chamber l through a cock c. If the pin p is prematurely destroyed, a projection q on the piston stem o enters a notch r in the cock, and prevents the opening of the cock.

Abstract: 1469624 Radar INTERNATIONAL STANDARD ELECTRIC CORP 1 April 1975 [8 April 1974] 13198/75 Heading H4D To detect a moving intruder over a substantially rectangular area (actually elliptical), a transmitter Figs. 1a, 4b is sited at one end of the area whilst the receiver is sited at the other end, the transmitter producing an r.f. signal, e.g. at 915 MHz, bi-phase coded (Figs. 1c, 1d) at a clock period Tb, e.g. 10 n.secs. such that at the receiver the maximum path difference #R MAX  between the direct transmitter/receiver path 108, 109 via the reflecting intruder on the edge of the elliptical area is just less than Tb.c. A crosscorrelation between the direct or reference received signal and the reflection derived signal thus gives a response varying with the path difference or range, e.g. as in Fig. 1e. The crosscorrelation is performed in a mixer 111 and an alarm is given if the response reaches a threshold of - 20 dB equivalent to AR MAX , e.g. 18 feet, the system being made proof against fixed objects by means of a doppler filter 113. Adaption of the system to a different shaped or sized area merely necessitates changing the clock frequency (control 112).
