Title: Modified polyamide yarns
IPC: C08G69/02
Filed: 1964-02-11
Abstract: Polyamide yarns of enhanced affinity to acid dyestuffs contain 0.1 to 25 wt. per cent of structural units <FORM:1021319/C3/1> wherein R is a cycloalkyl or C1- 4 alkyl radical and x and y are integers from 2 to 12.  They may be obtained by incorporating amine salts <FORM:1021319/C3/2> with the polyamide forming starting materials such as lactams, e.g. pyrrolidone, piperidone, caprolactam and their C-alkylated derivatives, or diamines and dicarboxylic acids, e.g. ethylene and tetra-, penta-, hexa-, octa- and deca-methylene diamines and alkylene dicarboxylic acids.ALSO:N,N1 - Dialkyl - N,N1 - di - gamma - aminopropyl alkylene diamines are prepared by the action of acrylonitrile on N,N1-di-alkyl alkylene diamines followed by hydrogenation of the product.  The resulting tetranures may be reacted with di-carboxylic acids to give salts. In examples: (1) N,N1 - dimethyl - N,N1 -di-gamma-aminopropyl ethylene diamine is prepared by reacting N,N1-dimethyl ethylene diamine with acrylonitrile and then hydrogenating the product; the tetramine is subsequently reacted with adipic acid to form a salt; (4) N,N1 - diisobutyl - N,N1 - di - gamma - aminopropyl hexamethylene diamine is similarly prepared from N,N1-diisobutyl hexamethylene diamine and converted to the adipate.

IPC: C07C51/43
Filed: 1917-04-24
Abstract: 115,080. Callimachi, M. T., Count. April 24, 1917. Salicylic acid.-Crude salicylic acid is purified by volatilizing it, mixing the vapours with a heated inert gas, such as dry air, nitrogen, carbon dioxide, or carbon monoxide, and cooling the mixture to such a temperature that the salicylic acid is condensed, and phenol and other impurities remain as vapours. The mixture of vapours and gas may be passed in series through condensers of decreasing temperature to obtain crystals of different size. The condensation may be brought about by increasing the pressure as well as by decreasing the temperature. In an example, salicylic acid is heated to about 170‹ C. in a vessel provided with a stirrer, and a current of air heated to 170‹ C. is passed through. The mixture of air and vapours is passed through a series of condensers kept respectively at about 130‹ C, 95‹ C, and 40‹ C.

Abstract: 1276624 Temperature responsive switches GENERAL ELECTRIC CO Ltd 19 April 1971 [11 Feb 1970] 6616/70 Heading H1N An electric kettle or the like is provided with a thermostat sensitive to boiling and with means for selecting "on-shot" or cycling operation and further means sensitive to a temperature above the boiling point to prevent over-heating. A fluid filled bulb (not shown) senses steam in the kettle expanding a bellows 21 when the water boils. By push rods 33, 35 the bellows acts on a movable contact 26 to open the circuit to the heating element (not shown). A snap acting blade 27 coupled to the push rods increases the speed of contact movement. A cam, 37, is movable to adjust the position of a lug 39 and determine whether the snap acting blade is self resetting for cycling operation or has to be manually reset, by the cam 37 or by a separate push-button (not shown), for "one-shot" operation. A snap acting bimetal 23 sensitive to the temperature of the heating element and operating at a temperature above the boiling point also acts, through a push rod 34, on the snap acting blade 27 to open the contacts 24, 25 if the kettle should boil dry. When the bimetal 23 has cooled it must be manually reset by a pushbutton (not shown) or by an extension of cam 37 (not shown). In an alternative embodiment (Fig. 1, not shown) the bellows and snap acting bimetal act directly upon the movable contact blade which may or may not be snap acting and which carries a small iron mass. A permanent magnet is movable into alignment with the mass so that when the contacts open the magnet retains them open. Normal cycling operation is restored by moving the magnet away. The magnet is mounted on a pivoted arm which also carries a cam for resetting the bimetal. The bulb and bellows 21 may be replaced by a second bimetal. In an alternative arrangement (not shown) the two thermal elements operate separate series connected contacts.
