Title: Improvements in connection with the purification of water in tanks
IPC: C02F1/52
Filed: 1946-12-24
Abstract: 621,919. Purifying and softening water. CANDY. F. P. Dec. 24, 1946, No. 37799. [Class 46] Chemical reagents, and precipitates formed by previous treatment of water with chemical reagents, are mixed with the water to be treated before there is material dilution of the incoming water by water previously dealt with, the precipitates being added before the reaction between the reagents and the water takes place, the treated incoming water flows continuously upwards through a divided off inner portion of a tank so that precipitate of relatively major weight is accumulated and is maintained in suspension therein, then flows downwardly and thereafter upwardly through accumulated precipitate of relatively minor weight in suspension in the remaining and major outer portion of the tank, from the top of which the purified water flows away. As shown in. the Figure, raw water enters by a pipe 6, withdraws sludge from a tank 1 by means of a Venturi 6A and pipes 7, and the mixture then passes to a mixing vessel 5 into which chemical reagents (e.g. lime, or lime and soda), are fed through a pipe 9. It then passes through a pipe 8 to an inner divided-off portion 2, of the tank 1, which it enters tangentially at the bottom, and in which it flows upwards through the comparatively heavy sludge maintained in suspension therein. It overflows from the top of the receiver 1, passing down inside a deflector 3, to the bottom of the outer and major portion between the deflector 3 and the tank wall, where lighter sludge carried over from the receiver 2 is likewise maintained in suspension. The treated water overflows into a collecting channel 4. The receiver 2 may be cylindrical, and a decreasing velocity effect may be achieved in the major portion of the tank either by increasing the diameter of the top of the tank, or by increasing the diameter of the bottom of the deflector 3. For use in a purifying process by coagulation the mixer 5 is omitted, the feed pipe 9 for the chemical, e.g., sulphate of alumina, discharging directly into the bottom of the receiver 2. The vertical portions of the pipes 6 and 8 are also omitted, the water pipe 6 feeding directly into the bottom of the receiver 2, and a Venturi 6A being provided as before. Power driven means (e.g., mechanical agitators) may be used in either case to maintain the sludge in suspension. The tank may be circular in plan, or square or many-sided. The sludge may be added to the chemical reagent as well as, or in place of, adding it to the water.

Title: Polymers containing gem dithioether and gem diether and/or ether groups and process for the preparation thereof
IPC: C08G18/52
Filed: 1966-08-25
Abstract: Polymers having in their backbone consecutively alternate gem dithioether, gem diether and/or ether groups each separated one from another by divalent organic groups are prepared by reacting a mercaptoalcohol and a carbonyl compound in the ratio of mercaptan to carbonyl groups of 2:1 to 1:1 in the presence of a strong non-oxidizing acid having a pka of 2.5 or less and in the substantial absence of added water and separating out the polymeric reaction product formed thereby by removal of the water by-product.  The reaction proceeds by first forming a dihydroxy gem dithioether which then reacts with excess carbonyl compound to form a polymer containing alternate gem dithioether/gem diether groups which is then isolated by cautious removal of water and any solvent present or alternatively molecules of dihydroxy gem dithioether compound and/or the hydroxyl containing alternating gem dithioether-gem diether linked polymer may be joined together by forcible removal both of the water of reaction formed in the first step and the water formed by etherification of hydroxyl groups, at elevated temperature and in the presence of a strong non-oxidizing acid.  Suitable carbonyl compounds have the formula <FORM:1086977/C3/1> wherein R and R1 may be hydrogen or hydrocarbon groups containing 1 to 25 carbon atoms and are preferably formaldehyde, acetaldehyde, benzaldehyde, acetone or methyl ethyl ketone.

Title: Anti-ozonants and use thereof in rubber compositions
IPC: C08K5/17
Filed: 1959-11-12
Abstract: Cracking of articles made of natural rubber and sulphur-vulcanizable and sulphur-vulcanized unsaturated synthetic rubbers is inhibited by incorporating into the rubber batch, from which the articles are prepared, an anti-ozonant in the form of a N,N1-dialkyl phenylenediamine hydrogenated in the benzene nucleus to an average extent equal to at least 40% of full hydrogenation of the nucleus, or a salt thereof.  Anti-ozonants of the type described are particularly suitable for white rubber articles; for they do not impart coloured stain to the rubber.  It is especially advantageous to utilize compounds in which the benzene nucleus is fully hydrogenated, i.e. the N,N1-dialkyl cyclohexylenediamines.  Among those specified are:-N-N1-di-2-isoheptyl-m-cyclohexylenediamine, N,N1-di-2-cyclohexyl-p-cyclohexylenediamine, and N,N1-di-3-octyl-o-cyclohexylenediamine.  The anti-ozonant is utilized in proportions in the range of 0,1 to 5% by weight of the rubber. The anti-ozonants also function to some extent as vulcanization-accelerators and anti-oxidants.  They also function as tackifiers so that, when used in compositions containing rubber and wax, excellent protection against ozone is provided without blooming out.ALSO:The invention comprises N,N1-dialkyl-cyclohexylenediamines and other N,N1-dialkyl-phenylenediamines which are hydrogenated in the benzene nucleus to an average extent equal to at least 40% of full hydrogenation of the nucleus, and salts thereof.  The compounds are prepared by hydrogenating a mixture of a nitroaniline, or dinitrobenzene, or phenylenediamine, and an alkyl or cycloalkyl ketone in the presence of Raney nickel catalyst or of rhodium metal deposited in carbon.  In an example, N,N1-di-2-isoheptyl-m-cyclohexylenediamine is obtained by hydrogenating a mixture of m-phenylenediamine, methyl isoamyl ketone and rhodium-on-carbon catalyst at a pressure of 300 to 500 p.s.i.g. and a temperature of 100 DEG -280 DEG F.  Among other cyclohexylenediamines referred to are:-N,N1-di-2-cyclohexyl - p - cyclohexylenediamine and N,N1-di-3-octyl-o-cyclohexylenediamine. Specified salts are the phthalates, benzoates, hydroxybenzoates, maleates, fumarates, sulphates, chlorides and nitrates.  The compounds are anti-ozonants for rubber (see Group IV(a)).

Abstract: 1,058,253. Telephone answering machines. SHIPTON ELECTRONICS Ltd. Oct. 15, 1963 [Oct. 15, 1962], No. 38933/62. Heading H4K. [Also in Division G5] In a telephone answering machine a magnetic tape or wire pre-recorded with an answer to an incoming telephone call is contained in a cassette which is readily removable from the machine, and incoming messages may be recorded on a separate magnetic tape in a separate cassette 7, Fig. 1 (not shown). Fig. 2 shows the part of the machine which receives the cassette (not shown). The cassette contains an endless tape which unwinds from the centre of a spool and rewinds on the periphery of the spool; the tape emerges from the cassette in two loops, one adapted to pass over the capstan 17 and the other adapted to contact the playback heads 18 and 19 under the influence of sprung felt pads mounted on the cassette. When the cassette is inserted, a recess in the cassette engages a pin 26 thereby pivoting a plate 21 and moving a pinch roller 20 mounted on the plate nearer to the tape and the capstan 17 which rotates continuously when the machine is switched on. When the machine detects an incoming call a solenoid 40 is energized and causes an arm 42 to pivot and engage plate 21, thereby moving the pinch roller 20 to engage the tape against the capstan 17. The tape may contain two tracks, one containing a pre-recorded answer and the other containing control signals. When the answer message finishes, the solenoid 40 is automatically de-energized and the tape drive stopped. If there is no cassette in the machine, the plate 21 is in the position shown and the arm 42 fails to engage it if the solenoid 40 is energized; also, with the plate in this position, a micro-switch 49 is closed so that if the machine is switched on a warning signal is given.
