Title: Process for the production of condensation products of formaldehyde with urea
Inventor: WOOD FREDERICK CHARLES
IPC: D06M15/423
Filed: 1956-03-09
Abstract: Aqueous solutions containing urea, formaldehyde, a crystalloidal precondensate of urea and formaldehyde and up to 10% by weight (based on the total weight of free and combined urea) of a polyethylene polyamine of general formula NH2(CH2CH2NH)xH when x is at least 2, are useful for textile-finishing operations.  Suitable polyamines are diethylene triamine, triethylene tetramine and tetraethylene pentamine.  The preferred mol ratio of formaldehyde to urea used is 1,0 to 3,5.  The solutions may be made by reaction of the ingredients without applied heat at a pH of 7-9 or by heating the mixed ingredients for a time less than is required for formation of an insoluble precipitate.  If desired the formaldehyde and polyamine may be reacted together before addition of the urea.  For treating textiles the solutions are used with acid or potentially acid catalysts, e.g. as described in Specification 827,645.  The textiles are then dried and heated to insolubilise the ureaformaldehyde resin. Many examples are given of the preparation of aqueous solutions and their use for treating textiles.ALSO:Textile materials are finished by impregnating them with an aqueous solution (see Group IV(a)) of urea, formaldehyde, a crystalloidal precondensate of urea and formaldehyde and not more than 10% by weight (based on the free and combined urea) of a polyethylene polyamine of general formula NH2(CH2CH2NH)xH, where x is an integer with a value of at least 2, and then heating the impregnated material with an acid condensation catalyst, preferably of the type described in Specification 827,645. The solutions may be used for improved crease resistance, to fix embossed or glazed effects, or to produce delustre.  The fabrics may also be treated with a polysiloxane.  A number of examples are given of the treatment of viscose rayon fabric, cellulosic fabric and satin.

Abstract: 1,177,205. Shift register. ASSOCIATED SEMI-CONDUCTOR MFRS. Ltd. 15 Feb., 1968, No. 7456/68. Heading G4C. [Also in Division H3] An output or inter-stage coupling of a shift register in the form of two chips of an integrated four-phase logic system comprises four MOST's connected as in Fig. 3, the input signal at 8 being applied to MOST 9. This signal is stored in the gate capacitance of the MOST and will be negative if a p-channel enhancement type is used. As shown, MOST 9 is on one chip and MOST's 10-12 are on the other, but MOST 10 could be on the first chip. During phase, 3 both the input 8 and the output at C are driven negative. Between the end of phase 3 and the end of phase 4, point 8 will assume a potential depending on the logic output of the preceding stage. If a "1" is present, this potential will be negative, keeping MOST 9 on and earthing the gate of MOST 11, so that C remains negative to give a "1" output. Noise on the connecting lead L will have no effect as this lead is at earth potential. If a "0" is present at 8 during phase 4, MOST 9 is turned off, and in the subsequent phase 1 the clock pulse turns on MOST's 10 and 11 and discharges C to earth to give the required "0" output. Noise on the lead L can only result in the "0" at C appearing earlier and will not give a false logic indication. The MOST's can be of the n-channel enhancement type with reversal of voltage polarities.

Abstract: 1305813 Fluid regulation JOHNSON SERVICE CO 17 Feb 1970 [3 March 1969] 7596/70 Heading G3H [Also in Division G4] A fluidic device, which can function either as an amplifier or as a logic device giving an AND or a NOR function, comprises two opposing and impacting main streams 3 and 4 which issue from respective nozzles 1 and 2, two primary control streams 16 and 17 which issue from respective nozzles 11 and 12 and which intersect the main stream 3, and two secondary control streams 22 and 23 which issue from respective nozzles 20 and 21 and which intersect the primary control streams 16 and 17 only. In the absence of pressure in the primary and secondary stream-issuing nozzles, the main streams 3 and 4 impact at 9 as a result of which a pressure signal is conveyed, through an output chamber 7, to a load 10. Should a stream issue from either or both of nozzles 11 and 12, this impact position 9 will move to the left as seen in Figs. 2, and so result in a lowering or complete cut off of the signal to the load 10. If  both the primary streams 16, 17 are issuing and only one of the secondary streams 22, 23 is issuing, the load signal will remain cut-off. Should however, both secondary streams 22, 23 issue and so deflect the two primary streams 16, 17 from interaction with the main streams 3, then the signal to load 10 will rise. In a modification, Fig. 7 (not shown), the corresponding primary and secondary stream-issuing nozzles may be staggered along the axis of the main stream. Furthermore, additional primary and secondary streams may be provided.
