Patent GB-976712-A (GB)
Title: Resinous condensation products
Inventor: HENSHALL ALBERT EWART
IPC: D06M13/137
Filed: 1961-12-27
Abstract: Acetal condensation products are obtained by reacting a water-soluble or water-dispersible formaldehyde resin precondensate with a water-soluble or water-dispersible polyacetal derived from an aldehyde containing less than 10 C atoms and a polyethenoxy compound containing at least 2-OH groups.  The precondensates are derived by interaction of H.CHO with a compound containing the group -CNH2 or the group <FORM:0976712/C3/1> where X is O, S or NH, e.g. urea/formaldehyde and melamine/formaldehyde condensates, dimethylol urea, trimethylolmelamine, hexmethylol melamine, dimethylolethylene urea, 1:3-dimethylol -5- -(b -hydroxyethyl)-hexahydrotriazin-2-one, the dimethylol derivative of glyoxal monoureide, the tetramethylol derivative of glyoxal diureide, the corresponding ethyl ethers and water-soluble or water-dispersible condensation products.  The polyacetals used may be made by known methods, e.g. as described in U.S.A. Specification 2,968,581, from aldehydes, e.g. formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde and glyoxal, and polyethenoxy compounds such as polyoxyethylene glycols, ethylene oxide condensates of glycerol and their monoesters with fatty acids, ethylene oxide condensates of primary amines and their derived quaternary ammonium salts, and ethylene oxide condensates of triethanolamine.  The reaction between the precondensate and polyacetal, usually in amount of from 0.1 to 5 pts. of the former per part (by wt.) of the latter, is effected by heating, preferably in the presence of an acid-reacting catalyst, e.g. ammonium chloride, ammonium thiocyanate or zinc nitrate. Examples 1, 4, 5 and 6 describe the preparation of the polyacetals and Examples 2, 3, 7 and 8 describe the preparation of the polyacetal condensation products in situ on synthetic fibres (see Division D1).ALSO:Antistatic properties are conferred on textile materials by forming an actual condensation product in situ, e.g. by impregnating the textile material with an aqueous solution or dispersion of the corresponding reactants and an acid-reacting catalyst, drying and baking, e.g. at 100 DEG  to 210 DEG C., the impregnated material to insolubilize the resin.  The actual condensation product is made from a water-soluble or-dispensible formaldehyde resin pre-condensate (viz. an aminoplast pre-condensate) and a water soluble or-dispersible polyacetal derived from an aldehyde containing less than 10 C atoms and a polyethenoxy compound containing at least 2-OH groups (see Division C3).  Examples 2, 3, 4 and 8 describe the above treatment of polyethylene terephthalate and nylon continuous filament fabrics.  U.S.A. Specification 2,968,581 is referred to.

Circuit 150 (Fig. 7, not shown) cyclically increases and then decreases the received frequency such as by  100 kHz by varying the up/down count of a counter 40 which has been set to the stored frequency representation in the memory 50. If no signal is received within the pullin range of the AFT circuit (Fig. 5, not shown) then circuit 160 (Fig. 8, not shown) is operated to cyclically vary the frequency by a larger amount such as  3 MHz by further up/down control of the counter 40. If a frequency is tuned to which is within the pull-in range of the AFT circuit the count of counter 40 is brought to that frequency under control of the AFT circuit. The modified count of the counter is then written into the memory 50 by operation of write circuit 60. If a channel selected by memory 50 has a tuning deviation within the pull-in range which is connected by the AFT circuit 120 by more than a predetermined amount determined by a counter 134 a signal Pm from a memory rewrite circuit 130 operates write circuit 60 to write in the corrected count of the counter 40 into the memory. The read/write operations of the memory 50, the coarse and fine adjustment of the counter 40 by switches 31C and 31F and the pulse width modulator 91 which functions as a D/A converter operate in a similar manner to Specification 1,518,712. AFT is inhibited by a circuit 140 when the power supply is turned on and during channel selection.
