Patent NL-204426-A (NL)
IPC: C09K23/00
Abstract: Dyeable films, fibres and fabrics are made by treating with a strong oxidizing agent, preferably in an acid medium and at an elevated temperature, a shaped article made from a polyacrylonitrile or copolymer of acrylonitrile substituted by a group containing bivalent sulphur (see Group IV (a)).  The introduction of the bivalent sulphur group may be effected on polymers whilst in shaped form and this method of operation may be used to produce locally oxidized structures, e.g. a fabric made from fibres of a copolymer of acrylonitrile containing halogen alkyl agroups is printed with a thiourea or thiocyanate in the presence of thickening agents such as methyl or carboxymethyl cellulose and then reacted by heating, followed by treatment with an oxidizing agent; alternatively a fabric made of an acrylonitrile polymer containing bivalent sulphur groups may be oxidized locally by means of an oxidizing agent in the presence of a resistant or thickening agent such as sodium polystyrene sulphonate.  The products of the process show affinity for dyestuffs, particularly basic dyestuffs such as Astra Cyanine B, a triphenylmethane dyestuff.ALSO:Dyeable shaped structures are made by treating with a strong oxidizing agent, preferably in an acid medium and at an elevated temperature, and prior to or after a shaping process, a polyacrylonitrile or copolymer of acrylonitrile substituted by a group containing bivalent sulphur which is either linked directly to a saturated carbon atom of the chain or is linked to the chain by another saturated carbon atom and in which group another carbon atom, adjacent to the sulphur, is linked by more than one valency to another sulphur atom or to oxygen or nitrogen.  The sulphur containing groups may be incorporated in the polymer molecules (a) by copolymerizing acrylonitrile with vinyl thioacetate in a dioxane solution with azodiisobutyronitrile as a catalyst, or (b) by causing polyacrylonitrile or copolymers of acrylonitrile to react with compounds such as sodium and ammonium thiocyanates, sodium alkyl xanthates, alkali thio- or dithio-carbamates, ethylene thiourea, N-butyl ethylene thiourea and mercaptobenzothiazole; preferred polymers are copolymers of acrylonitrile with monomers containing reactive groups such as vinyl chlorethyl ether, chloracrylonitrile, chlorethyl methacrylate, hydroxyethyl acrylamide benzene sulphonate, bromobutyl acrylamide and vinyl chloroacetate, and, optionally, other monomers such as methyl acrylamide, vinyl acetate and vinyl pyrrolidone may also be present.  Specified oxidizing agents are chlorine or bromine in the presence of water, hypochlorous or hypobromous acid, benzoyl peroxide peracetic or perbenzoic acid, N-chlorurethane and N-chloroxazolidone, the action of which may be accelerated by means of oxygen carriers such as anthraquinone or anthraquinone sulphonic acid.  The oxidation reaction is preferably carried out on the polymeric material in the form of fibres or films which may then be dyed, particularly with basic dyestuffs.

Title: Spray system for cooling liq. bodies - by forcing air through liq. spray chimney
IPC: B05B17/08
Filed: 1976-10-25
Abstract: A novel liq. spray system for cooling a body of liq. comprises a press. nozzle for producing from the surface of a liq. a liq. spray chimney of inverted frusto-conical shape. The liq. spray chimney encloses a mechanically generated air draft produced by a fan having an exhaust outlet positioned within the frusto-conical spray trajectory configuration. The system is used for cooling water in a river or tank heated by the hot discharge from nuclear or fossil-fuel powered electricity generators. Cooling is not dependent upon natural wind conditions to produce the air velocities necessary for efficient cooling. Liq. loss from the system is reduced because the droplets in the liq. spray chimney are sufficiently large not to be entrained and carried away in the air draught.

Patent NL-7806675-A (NL)
IPC: F16K1/22
Filed: 1978-06-20
Abstract: An installation control valve, for example for use in a fire fighting sprinkler installation, comprises a pivotal butterfly valve disc co-operable with a movable stop, which in one position abuts the valve disc to retain the valve closed against pressure forces acting thereon. A retaining mechanism is releasably held to resist stop movement and so prevent valve disc opening but is operable under a predetermined condition to permit stop movement from said one position to a second position. When the stop is in the second position, unequal pressure forces on either side of the valve disc cause same to move thereby opening the valve.

Abstract: In a process of manufacturing screen material a metal matrix is subjected to an electrolytic metal deposition by using an electrolytic bath containing a brightener, the liquid of the bath being forced to flow through apertures in the cathode toward the anode. The metal deposits grow substantially perpendicular to the lands of the matrix and so form a screen having apertures of approximately the same size as the apertures of the original matrix. The screen can be removed from the matrix by previously coating the latter with a separating agent such as beeswax. An installation for performing the process of the invention comprises a perforated cathode as matrix being fixed to cathode fixing means, a perforated anode being fixed to anode fixing means and a pump for providing a forced flow of liquid through the apertures of the cathode toward the anode.

Title: Supply circuit for electric razor motor - has bridge supplying three parallel branches ensuring for wide range of AC inputs
IPC: H02M3/135
Filed: 1985-11-15
Abstract: The a.c. input (1,2) is fed via a switch (3) and a first capacitor (4) and resistor (5) to a rectifier bridge (6). The bridge output (7,8) is fed to three parallel branches: one contains a 'crowbar' thyristor (9), one contains a Zener diode voltage detector (10,11) and the third contains a blocking diode (12) in series with the motor (13). As the bridge output rises, a capacitor (14) is charged via the blocking diode (12) and a PNP transistor.
