Title: Improvements in or relating to the production of aqueous dispersions of partially condensed hydrophilic urea-formaldehyde/alcohol resins
Inventor: BERRY WILLIAM
IPC: C08G12/42
Filed: 1949-04-07
Abstract: Aqueous dispersions of partially condensed urea- or thiourea-formaldehyde-aliphatic alcohol resins, the colloidal particles of which carry a positive charge, are prepared by partially condensing by heating in an aqueous acid medium an ether of a methylol-urea or methylol-thiourea and a water-miscible alcohol and adding to the aqueous medium a water-soluble cation-active compound, the molecule of which comprises a quaternary ammonium or phosphonium or ternary sulphonium group and, attached directly to the N, P or S atom, an alkyl straight-chain group containing at least 8 carbon atoms or a branched chain group containing at least 12 carbon atoms. The "onium" compound should have a surface tension in 0.5 per cent aqueous solution less than 50 degrees/cm. and may be added before, during or after the condensation.  Specified alcohols are methanol, ethanol, propanol, isopropanol, ethylene, propylene and diethylene glycols and glycerol.  The resin constituents may be condensed by refluxing urea or thiourea, formaldehyde and the alcohol in the molar ratio 1 : 2 to 3 : 0.3 to 1, for 1-4 hours in aqueous solution adjusted to pH 5.0 with acetic acid and with a small quantity of sodium acetate as a buffer.  After refluxing the resin dispersion is cooled and neutralized to pH 7, e.g. with aqueous caustic soda.  In examples dispersions were made from the following materials: (1) urea, formalin, ethanol and cetyl trimethyl ammonium bromide; (2) thiourea, formalin, glycerol and cetyl pyridinium bromide; (3) urea, formalin, propanol, cetyl trimethyl ammonium bromide; (4) urea, formalin, ethylene glycol, cetyl trimethyl ammonium bromide, the last being added during the condensation; (5) as in (4) but with the addition of the "onium" compound after the condensation but before cooling; (6) urea, formalin and ethanol, cetyl ethyl methyl sulphonium bromide being added during the condensation; (7) urea, formalin, ethylene glycol, cetyl triethyl phosphorium bromide.  The dispersions of the invention may be used in the production of moisture-proof film as described in Specification 677,183.

Title: Carry or Borrow System for Arithmetic Computations
Inventor: BOOKER ROBERT KENNETH
IPC: G06F7/506
Filed: 1967-03-01
Abstract: 1,164,010. Arithmetic carry and borrow means. NORTH AMERICAN AVIATION Inc. 1 March, 1967 [7 June, 1966], No. 9740/67. Heading G4A. Carry or borrow information in an arithmetic operation is produced by logic groups each comprising at least two logic orders representing consecutive operand bit positions, alternate groups producing the information in true form and the other groups producing it in inverse form, the information being produced from the last logic order in each group without incurring bit time delays in propagating through preceding orders in the group. Fig. 1 shows carry generation for a parallel adder, the addend and augend being A, M. The gates shown are NAND gates, and junctions between gate outputs perform an ANDing function. The carries from two successive orders are generated simultaneously, both being in true form in even-numbered pairs of orders and both being in inverse form in odd-numbered pairs of orders. The Figure is self-explanatory, it being noted that the carry C o  into the carry generating means 20 for orders 1 and 2, for example, is applied directly to gating means 20a, 20b relating to each of the orders, and the gating means for order 2 receives directly the addend and augend bits for order 1 as well as those for order 2. The adder with carry means may be converted into a subtractor with borrow means by reversing the connections from the augend (now minuend) register. NAND gates may be provided to allow the connections to be made in either way selectively. NOR gates may replace the NAND gates. Use in multiplication and division is mentioned.

The shoot is preferably of a size to form a manhole and is closable by a heat-insulated plug 8 with handle 6 and' by an outer cover 7. The melted ice water is preferably circulated by a pump X and spray 30 over the ice, and a meter V for the ice water is located between the tank and a waste pipe 21 so that the quantity of ice delivered to the tank may be ascertained without weighing the solid ice. The liquid circulated to the cooling elements is led through the outer conduit of a concentric tube heatexchanger U located at the bottom of the tank, and water from a town main S is circulated through a branch circuit T and the inner tube of the heat interchanger. In cold weather, the tank is filled with water to form a reserve of cold and the circulating liquid is cooled merely by the water from the main. The pipes F, G conveying the liquid to and from the cooling elements extend partly in a vertical direction at 17 in the ice-tank, and circulation is effected by a pump O in pipe G. Warm liquid returned from the elements may be recirculated with the cooled liquid when the temperature in the elements is too low. Each local circuit of cooling-liquid is provided with an automatic vent valve K at the top, and a filling and vent device L is located at the highest point of the circuit.

Abstract: 756,600. Centrifugal separators. YARROW & CO., Ltd. April 5, 1955 [April 5, 1954], No. 9942/54. Class 23. In an oil cleaning plant comprising a centrifugal separator 4, a pump 5 having an output corresponding to the separator capacity for maximum separating efficiency, and a pump 5a having an output at least equal to that of the pump 5, the pump 5 is in the feed line to the separator and the pump 5a is arranged to be either connected in parallel with the pump 5 or to be connected in the discharge line of the separator. An oil tank 1 is connected to the separator by a feed line a, a<SP>1</SP>, a<SP>2</SP> and by a return line a<SP>3</SP>, a<SP>4</SP>, the pumps being connected by branch lines to the lines a, a<SP>1</SP>. Multi-way valves 7a, 7b permit the pump 5a to be isolated from the feed line and be connected to the discharge line. When the valves 7a, 7b are set so that both pumps feed the separator, the rate of flow is controlled by a valve 19a in a by-pass 19 and a heater 9 may be connected to the separator feed line. When the valves 7a, 7b are set so that the pump 5a is connected to the separator discharge line and valves v<SP>1</SP>, v<SP>2</SP>, v<SP>3</SP>, v<SP>4</SP>, v<SP>10</SP> are closed, the pump 5 feeds the separator and the pump 5a delivers clean oil from the separator through a line a<SP>3</SP>, b<SP>4</SP>, 12a, 11b, 11a to a tank 11 at a higher level than the separator. The plant may be used to clean oil from a tank 13, the valves v<SP>7</SP>, 7a, 7b being adjusted and the valves v<SP>1</SP>, v<SP>2</SP>, v<SP>3</SP>, v<SP>4</SP>, being closed so that the pump 5a feeds clean oil from the separator to a tank 12 at a higher level than the tank 13. By further adjustment of valves the pump 5 may deliver oil from a turbo-generator T to the separator, and the pump 5a may return the cleaned oil from the separator to the generator. A solenoid operated valve 18, which may be connected with the electrical circuit of the separator motor 14, prevents flow of oil to the separator when the separator is not running.

Title: Improvements in or relating to the production of alumina hydrate compositions
IPC: B01J37/02
Filed: 1956-03-29
Abstract: The alumina base in a reforming catalyst as claimed in the parent Specification comprises also a platinum group metal (platinum, rhodium, palladium or iridium), is prepared by mixing at a pH of 7-9.5 and a temperature of 70-160 DEG  F. an aqueous aluminium salt (e.g. chloride, sulphate or nitrate) with aqueous ammonium hydroxide, separating and washing the precipitate at a pH of at least 7, to form alumina trihydrates and dehydrating the trihydrate composition.  The aged composition comprises the crystalline trihydrates Gibbsite, Randomite and Bayerite together with Boehmite and amorphous alumina; to obtain a preferred composition containing 65-95% trihydrate alumina the washed precipitate may be aged at 70-170 DEG  F.; seeding with the desired trihydrate form accelerates conversion.  The reactants may be continuously mixed as flowing streams in a pipe, pump or small mixing vessel, and in this case reaction is rapid so that seeding is not practical; it is preferred to maintain a constant ammonium salt concentration during precipitation and to stir the resultant slurry before filtration.  In the first example, the filtered slurry is washed at 70-80 DEG  F., reslurried in water and the pH adjusted to 9 with ammonia, washed and filtered and the process repeated.  The final filter cake is aged by standing at room temperature.  The filter cake is dispersed in water and an ammonium fluoride solution added.  Thereafter chloroplatinic acid solution and hydrogen sulphide solution are successively added with stirring.  The slurry is dried at 120 DEG  C., mixed with an organic die lubricant, heated at 900-935 DEG  F. with a mixture of air and nitrogen, the air being slowly increased, and finally with air at 900 DEG  F.  In the second example the precipitate is obtained from aluminium chloride (prepared from aluminium metal and hydrochloric acid) by reaction with ammonium hydroxide in a pipe in which the flowing streams are reacted for 1 second before discharge when the mixed stream impinges on the walls of the vessel or the surface of the slurry therein.  The treatment of the product is similar to that in the first example, except that the ammonium fluoride is omitted and the impregnated composition is spray-dried, and thereafter mixed with a number of similar but impregnated samples, and the mixture moistened, worked in a dough beater, extruded and broken to form pellets which are dried at 110 DEG  C. and calcined at about 480 DEG  C. first in nitrogen and then in air.
