Title: Process for avoiding precipitates in ice colour padding solutions
IPC: D06P1/12
Filed: 1950-02-09
Abstract: The invention comprises polyalkylenepolyaminoalkyl carboxylic acids of the general formula R2N-(alkylene-NR)n-alkylene-NR2 in which at least one R is an alkyl carboxylic acid residue and the others are hydrogen or two of them together form an alkylene group, n is such that the compounds contain at least 20 alkyleneamine groups in the molecule, and the proportion of nitrogen atoms to alkyl carboxylic acid groups is from about 3.4 to about 5 to 1.  They are prepared by acting with ammonia on alkylene halides, removing the lower molecular amines by distillation, if desired, treating the polyalkylenepolyamines obtained with more alkylene carboxylic acid groups, e.g. by the action of a monohalogenalkyl carboxylic acid salt or (in the case of introducing an acetic acid group) by the action of formaldehyde and hydrocyanic acid, followed by saponification.  The intermediate polyalkylene polyamines may also be prepared by polymerizing ethyleneimine.  Examples are given of the preparation of polyethylenepolyglycine from ammonia, ethylene chloride and sodium monochloracetate; the preparation of polyethylenepolyaminopropionic acid and polyhydroxypropylenepolyglycine (from glycerol dichlorohydrin) also are referred to.ALSO:The formation of precipitates in ice colour padding solutions is avoided by adding to the padding solution a small amount of a polyalkylenepolyaminoalkyl carboxylic acid.  The polyalkylenepolyaminoalkyl carboxylic acid may have the general formula R2N-(alkylene-NR)n-alkylene-NR2 in which at least one R is an alkyl carboxylic acid residue and the others are hydrogen or two of them together form an alkylene group, n is such that the compounds contain at least 20 alkyleneamine groups in the molecule, and the proportion of nitrogen atoms to alkyl carboxylic acid groups is from about 3.4 to about 5 to 1.

IPC: F16H61/02
Filed: 1949-02-09
Abstract: 668,385. Variable-speed gearing. HOBBS TRANSMISSION, Ltd. May 9, 1950 [Feb. 9, 1949], No. 3519/49. Class 80 (ii). In variable-speed gearing in which friction clutches and/or brakes are actuated by pressure fluid under control of a selector valve movable into different positions for different speeds means are provided whereby the operating pressure is varied for certain of the friction devices. As shown a selector valve member 6 controls the supply of pressure fluid through passages 7, 8 and 9, 10 to operate respectively friction clutches and re-action brakes of an epicyclic gear. Pressure fluid supplied from pumps driven from the input and output shafts of the gear is delivered through passages 143, 145 to a bore 13 of the valve 6 where it is controlled by a piston valve 31 co-operating with either of escape ports 26 or 15 to regulate the pressure supplied through ports 16, 17 or 18 to the brake operating passages 9, 10 according to the selected position of the valve 6. The pressure fluid escaping past valve 31 passes to a chamber 27 where it is further regulated by another valve 28 controlling a passage 30 to exhaust to provide a constant pressure supply for operating the clutches through grooves 20, 21, 22, 23 in the valve 6 which grooves are all in communication with the chamber 27 through passages (not shown) and which align successively with the clutch operating passages 7, 8. Exhaust grooves 33, 34, 35, 37, 38 relieve the brake or clutch operating devices of pressure as required and a ball detent 24 locates the valve member 6 in positions giving three speeds, neutral and reverse by engaging recesses 25 therein. In a modified arrangement providing for four forward speeds the control valve 31 is arranged separately from the valve 6 in its own bore and has a reduced stem to reduce its effective area and allow better spring control. The openings and grooves in the valve 6 are arranged so that it can be operated from a lever working in a gate. In this case also the valve controlling the clutch operating pressure is interconnected with the engine throttle so that a clutch pressure in accordance with the throttle opening, and hence engine torque, is obtained. In a further arrangement for a gear having five forward speeds the control valve 31 for the reaction brake pressure is housed within the selector valve as in Fig. 1 and both the valve 31 and control valve 28 for the clutch operating pressure are provided with reduced stems with balancing pressure acting on the rear of each valve.

Title: Method and system for distilling water
IPC: C02F5/04
Filed: 1966-01-26
Abstract: Water, e.g. sea water, which is to be distilled is first treated with a water-soluble polyphosphate and then heated, after which an acid (or a salt which forms acid on hydrolysis) is added to the water before it is introduced into the still, e.g. a vapour-compression still provided with a de-aerator.  Suitable polyphosphates are:-tetrasodium pyrophosphate, sodium tripolyphosphate, and sodium hexametaphosphate.  In the case of sea water, 0.5 to 10 parts of polyphosphate are added per million parts of feed water.  After addition of the polyphosphate, the feed water is divided into two streams, one of which is heated by passing it in heat-exchange with the distillate, while the other stream is heated in heat-exchange with the brine blowdown.  The two streams, which leave the heat-exchangers at a temperature of about 190 DEG F., are then reunited, and the acid substance is added. Suitable acid substances are:-sulphuric, hydrochloric, phosphoric, nitric, sulphamic and citric acids, sodium bisulphate, ferric chloride, and aluminium sulphate.  The acidified acid is then passed, via a de-aerator, into the still.  The pH of the brine withdrawn from the still is continuously checked by an instrument which automatically controls the acid addition to the feed to maintain the brine at a pH of 7.0 to 7.4.  The pH of the distillate may be adjusted, as desired, with acid or alkali.  The distillate may also be treated with chlorine-water.
