Title: Improvements in water-insolubilized natural and synthetic polymers and method for producing same
IPC: C08B37/00
Filed: 1963-05-13
Abstract: A process for decreasing the solubility in water of non-amylaceous, non-proteinaceous, water-soluble polymeric materials comprises heating said polymeric material in the presence of an aqueous solution of ammonium zirconyl carbonate (AZC) having a pH from 5 to 10 to liberate ammonia from the AZC, the polymeric material being capable of forming coordinate or covalent bonds with zirconium or of forming a zirconium carboxylate salt with the thermal decomposition product of the AZC. The process can be effected with the polymeric material in the form of a film, filament or web, or coated on a substrate, e.g. paper. When coated on a substrate, the polymeric material is applied from an aqueous solution which may also contain some or all of the AZC used.  Pigments may be included in these coating compositions, e.g. clay, calcium carbonate, titanium dioxide, blanc fine or satin white; other additives such as defoamers and dyes may also be included.  The insolubilization of the polymeric material is catalysed by the presence of ammonium chloride. Examples of suitable polymeric materials are cellulose derivatives, e.g. cellulose ethers; natural gums and plysaccharides, e.g. Guar, Locust Bean, Tamarind seed, Corn Hull and Karaya gums, and Irish moss or carrageen; synthetic polysaccharides, e.g. fermentation products of sucrose; maleic copolymers, e.g. styrenemaleic anhydride copolymers in the half-amide half-ammonium salt form or containing ester and carboxylic acid side groups, and vinyl methyl ether-maleic acid copolymers; polyacrylamide and methylolated polyacrylamide; potassium salts of polymeric acids, e.g. polyacrylate; polyvinyl alcohol and alkali-soluble polyvinyl acetate; polyvinyl-pyrrolidone.ALSO:Paper is coated with an aqueous solution having a pH from 5 to 10 and containing a polymeric material, clay pigment and ammonium zirconyl carbonate (AZC), and then heated to about 180 DEG C. for 1 1/2 minutes to dry and insolubilize the coating.  In a modification, the AZC is omitted from the polymer solution and is applied afterwards to the paper in a separate aqueous solution, and the paper is then heated as described above.  The clay pigment can be replaced by calcium carbonate, titanium dioxide, blanc fixe or satin white.  As polymeric material there are used cellulose ethers, natural gums and polysaccharides, a synthetic polysaccharide obtained by fermentation of sucrose, modified styrene-maleic anhydride copolymers, polyacrylamides, polymeric acids in potassium salt form, polyvinyl alcohol, vinyl acetate copolymer and polyvinyl pyrrolidone.

Title: Signal selector device
IPC: H04L15/26
Filed: 1958-06-13
Abstract: 845,157. Alarm signalling systems. INTERNATIONAL MARINE RADIO CO. Ltd. June 13, 1958 [June 14, 1957], No. 19006/58. Class 40 (1). In a device adapted to respond to an alarm signal consisting of a given number of " dashes," whose length can vary between predetermined limits, separated by intervals of a predetermined maximum length, means for setting the minimum length of acceptable dashes comprises two monostable flip-flops T1, T2 which control a third monostable flip-flop T3 maintaining a first gate G1 open during the interval corresponding to the difference between minimum and maximum dash lengths so that a dash ending during the time the gate is open gives an output to trigger a monostable flip-flop T4, setting the interval of maximum length between acceptable dashes, the output also being supplied to a register REG where it is counted, the flip-flop T4 controlling a gate G2 to prevent the register being reset during a time equal to the predetermined maximum interval after the receipt of an acceptable dash. An acceptable dash is to be from 3.5 to 6 seconds in duration and the flip-flops T1 and T2 accordingly measure 3.5 seconds; 0.25 second in the first and 3.25 seconds in the second. As T2 returns to its stable state, the flip-flop T3 is triggered to its unstable state and remains in it for 2.5 seconds, holding gate G1 open so that when the dash signal at A ends, a pulse can pass to set flip-flop T4. Reset circuits R1, R2 and R3 respond to the termination of the dash to reset their associated flip-flops if they are not already reset. The flip-flop T4 remains in its unstable position for 1.5 seconds, the interval of a maximum space. While T4 is in its unstable state, gate G2 is closed and when it resets, a signal passes to register 10. When three or more acceptable dashes have been recorded, an output from the register actuates an alarm. Gate G2 resets the register whenever no dash has arrived for the period of 1.5 secs., the absence of a dash signal then producing a resetting signal. The register comprises a pair of flip-flops connected to count up to four, connections being made to actuate the alarm when a count of three or four is registered. Each flip-flop may have a neon lamp which is lit when the flip-flop is in the unstable condition. Specification 765,934 is referred to.

Title: Improvements relating to the manufacture of sponge rubber
IPC: C08J9/04
Filed: 1927-07-19
Abstract: 284,938. Near, R. J. July 19, 1927. Flexible tubes.-In the manufacture of spongerubber articles, for example, tubes, a vulcanized skin is first formed on the surface of a mass of dough prior to the generation of gas within the mass, and the whole mass is then hot-vulcanized. The formation of the skin enables hot vulcanization to take place without a mould and takes advantage of the fact that a mass expanding under surface restraint assumes a substantially-regular spherical, cylindrical or D-formation. A continuous length of cord may be formed by extruding dough in the form of a rod, passing the rod through a cold vulcanizer, coating the surface vulcanized rod with powdered chalk to prevent adhesion and winding spirally without a mould for the hot-vulcanization process. A tube is similarly formed by using a flexible core, e.g. a previously-formed cord.
