Title: Manufacture of new polyamides
IPC: C08G69/26
Filed: 1946-12-13
Abstract: Equimolecular proportions of 1 : 6-diamino-6-methyl-heptane and an aliphatic dicarboxylic acid are heated together to give a polyamide. Amide forming derivatives or low molecular weight polymers or the preformed salt may be used.  The reactants are heated until filaments formed from a melt of the polyamide can be cold-drawn into fibres. The acids include oxalic; glutaric; adipic; pimelic; suberic; azelaic; sebacic; brassylic; tetradecanedioic; octadecanedioic; p-phenylenediacetic; hexahydroterephthalic and 1 : 3-cyclopentane dicarboxylic acids. The heating, which is usually at from 200 DEG  to 300 DEG  C. in the presence or absence of solvent or catalyst and preferably in the absence of air or oxygen, is performed under conditions allowing the removal of water, e.g. under reduced pressure, at least during later stages.  A mono-functional amide-forming reactant may be used to stop the reaction at any stage as described in Specification 495,790.  The products are soluble in methanol and ethanol and may be made into films forming strongly adhesive bonds to glass, metals and similar surfaces.  Solutions in water-miscible organic solvents on mixing with water provide stable aqueous dispersions.  In an example, a solution of 1 : 6-diamino-6-methylheptane in ethanol is added to an ethanol solution of adipic acid, the white crystalline salt separating out on standing.  The salt is heated for 3 hours at 220 DEG  C. in a closed vessel, which after cooling is opened and heated at 255 DEG  C. for 1 hour at atmospheric pressure and then for 12 hours at 0.3 mms. pressure.  The product, which has an intrinsic viscosity of 0.74, softens at 100 DEG  C. and can be spun at 165 DEG  C. to filaments which may be cold-drawn.ALSO:1 : 6-Di-amino-6-methyl heptane is converted into an aliphatic dicarboxylic acid salt by interacting equimolecular proportions of the amine and adipic acid in ethanolic solutions, the salt crystallizing out on standing.  Reference is made to the formation of salts of the amine with other aliphatic dicarboxylic acids, e.g. oxalic, glutaric, pimelic, suberic, azelaic, sebacic, brassylic, tetradecanedioic, octadecanedioic, p-phenylene diacetic, hexahydro-terephthalic and 1 : 3-cyclo-pentane dicarboxylic acids.  The salts are starting materials for the production of polymeric amides (see Group IV (a).

Title: Method and apparatus for testing internal combustion engines
IPC: F02P17/04
Filed: 1972-08-09
Abstract: 1379070 Digital measurements SCANS ASSOCIATES Inc 9 Aug 1972 [22 Nov 1971] 37172/72 Headings G1U U12A6 U12B9 and U12B6 The timing angle of an internal combustion engine is calculated from (a) the time between the occurrence of the spark (or an event having a known temporal relationship to it) and the top dead centre position of the piston (or a position with a known temporal relationship to this), and (b) the time for a predetermined number of revolutions of the crank-shaft. The times (a) and (b) are measured by counting clockpulses from an oscillator. An arithmetic unit performs the calculation, doing division by repeated addition of the negativized divisor until a change of sign, and multiplication (by a constant) by repeated addition. The timing angle is displayed, as are the R.P.M. (also calculated by the arithmetic unit). If the R.P.M. does not fall within certain limits, the timing angle display is inhibited, but if it does, the timing angle is compared with limits and if it falls outside them, a servo-mechanism adjusts the distributer in one direction or the other and the measurement repeats. A test switch feeds standard values in to test the system. Another switch controls the number of revolutions of the crank-shaft over which time (b) is measured.

A method of producing cold-cured polyurethane foam sheeting, in particular for flooring materials, as described in Specification 1,048,267, comprises feeding a polyurethane foam-forming composition between conveyers 1, 2 which move at substantially the same speed and allowing the composition to expand therebetween, the resultant foam having a density in the range from 4-12 lb./cu. ft. and a load-bearing capacity in the range of from 1À0-12À0 lb./sq. in. at 25% compression, 2À5-30À0 lb./sq. in. at 50% compression and 13À0 to 138À0 lb./sq. in. at 75% compression. The conveyers are preferably of stainless steel and the upper one is vertically adjustable, the moulding space 6 being defined laterally by plates having gas outlets 7, Fig. 2 (not shown). The foam-forming composition is fed from a horizontally reciprocable dispenser 10, having a fan-shaped nozzle 12, on to a backing material 8, made of, e.g. paper, P.V.C. or woven fabric, and is evenly spread on the backing layer by the action of roll 4. Paper or the like sheeting 9 is fed in contact with the upper conveyer 2 to prevent the foam sticking thereto and the paper may contain a release agent, e.g. silicone, so that if desired, it may be stripped from the final product. Final curing may be effected using a radiant heater 14 and the product is cut by a guillotine 15. Also the edges of the sheeting may be trimmed. In a second embodiment, Fig. 4 (not shown), particularly intended for the production of polyurethane foam sheeting without a backing, the lower conveyer 1 extends under dispenser 10 and both conveyers are coated with a release agent, e.g. a wax solvent, using sprays 19, 20. The constituents of the polyurethane foam-forming composition and of the backing layer are given in the above-mentioned Specification.
