Abstract: 1,025,368. Hot-water boilers. RADIATION Ltd. June 1, 1964 [May 24, 1963], No. 20898/63. Heading F4A. In a gas or oil-fired circulator of the kind described in Specification 737,283, the water body has tank connections 7, 8 leading into water chambers 4, 6 which communicate with the heating chamber through openings 3, 5, the chambers 4, 6 being interconnected by a passageway 11 having a restricting throat 12 and containing the thermostat (not shown) which controls the burner operation. For tanks with a single opening for the circulator a pipe carrying hot water to the top of the tank is screwed into the opening 3, the connection 8 is blanked off and the circulator is secured to the opening by the connection 7. In operation, water flows in through the connection 7, downwardly in the passageway 11 and up through the heating chamber to discharge to the top of the tank through said pipe. For tanks with two openings both connections 7 and 8 are used. In this case, water enters the circulator through connection 8, passes into the heating chamber through opening 5 and returns to the tank through opening 3 and the connection 7, the restriction 12 substantially preventing water flow between the chambers 4, 6 through the passageway 11.

Abstract: 773,744. Applying liquids to webs. KUSTERS, E. July 20, 1955'[July 29, 1954; Jan. 5, 1955], No. 21061/55. Class 140. Apparatus for the treatment of textile fabric and like fabrics with liquids wherein the surface of a drum or roller round which the fabric passes in a liquid receptacle is either covered with a porous or absorbent material, capable of taking up liquid, and is resilient and formed to allow the liquid to pass therethrough to the interior of the drum or roller and the drum or roller is mounted eccentrically whereby so it rotates, vibratory movement is imparted thereto thereby ensuring a flow of liquid relative to the fabric backwards and forwards from one surface to the other of the fabric as it travels with the drum or roller so that all parts of the fabric are thoroughly soaked with the liquid. Textile material is passed round a drum 1 having a porous or absorbent resilient cover 2 eccentrically mounted to rotate on a shaft 3 in a trough 4 of treating liquid. The drum is either frictionally driven or is driven through .suitable gearing. The material is pressed against the surface of the drum by balls 9 floating on the treating liquid and retained in position by plates 10, and by heavy balls 5 in a container 6 retained at the ends by partitions. A roller 8 exerts pressure on the drum before the material passes under the balls 5. In a modification, the drum is surrounded by rollers mounted on axes and alternately pressed into the porous coating and released therefrom by the vibratory movement of the drum. The leading in roller may be driven using the same drive as that for the exit roller external to the drum, the material being pressed by a further roller. In a further modification the drum is formed of a wire mesh sleeve mounted by supports on a hollow shaft eccentically mounted.

Title: Improvements in motor control systems of magnetic tape transports
IPC: G11B15/58
Filed: 1968-05-03
Abstract: 1,215,205. Automatic control systems. POTTER INSTRUMENT CO. Inc. May 3, 1968 [June 8, 1967], No.21144/68. Heading G3R. In a magnetic tape transport whose reels 12, 14 and capstan 18 are respectively controlled by a known buffer loop control system comprising members 26, 28, 34, 38 and by a motor control system generally similar to that described in copending Specification 1,215,204, the control system for the reels is modified so that during a rewind operation the reel motors 36, 42 are respectively controlled by the upper senser 26 in the file buffer 22 and by the lower senser 28 in the machine buffer 24. The arrangement is such that the motors 36, 42 are rotated anti-clockwise at normal speed when the loops in buffers 22, 24 are respectively greater than or less than predetermined lengths dependent on the senser positions and are individually electrodynamically braked when the respective loop length condition is not fulfilled. A rewind signal applied at terminals 59 disenables AND gates 25, 27, 29, 31 to prevent normal clockwise and anti-clockwise control of the motors 36, 42 and enables AND gates 62, 66 to respectively apply the signal from the upper senser 26 of buffer 22 to the anti-clockwise control circuit 57 and the signal from the lower senser 28 of buffer 24 to the anti-clockwise control circuit 63. Thus the motor 36 is driven anti-clockwise or electro-dynamically braked according to whether the loop in buffer 22 is below or above the senser 26 and the motor 42 is driven anti-clockwise or electro-dynamically braked according to whether the loop in the buffer 24 is above or below the senser 28. The modification is applicable to systems wherein it is difficult to increase the speed of the reels during rewind, e.g. the driving motors 36, 42 have permanent magnet fields.

Filed: 1960-06-16
Abstract: Filamentary materials are made by meltspinning synthetic linear fibre-forming polymers such as polyamides, polyureas and polyurethanes having in at least 50% of the recurring units of the main polymer chain a structural unit of the formula:- <FORM:0898889/IV (a)/1> where X is oxygen or sulphur and having from 55 to 160 gram equivalents of amine end groups per 106 grams of polymer, in which there has been dissolved, prior to extrusion, at least 0,05% by weight, based on the weight of the polymer, of one or more of the following phosphorus compounds:-  <FORM:0898889/IV (a)/2> and a compound of the formula:-  <FORM:0898889/IV (a)/3> where R is an alkyl, cycloalkyl, alkenyl, aryl, aralkyl or aralkenyl group, n is a whole number equal to the valency of the metal, Z is hydrogen or an alkyl, cycloalkyl, alkenyl, aryl, aralkyl or aralkenyl group, or an alkyl substituted ammonium group, or R and Z together are an alkylene group when joined to form a ring structure.  Preferably the polymer is a polyamide having in at least 90% of the recurring units of the main polymer chain a structural unit of the formula:- <FORM:0898889/IV (a)/4> or <FORM:0898889/IV (a)/5> wherein X is oxygen or sulphur, A is a divalent organic radical and each B is a monovalent organic radical or hydrogen, and contains from 60 to 120 gram equivalents of amine end groups per 106 grams of polymer and at least 0,2%, based on the weight of the polymer, of the phosphorus compound(s).  Preferred phosphorus compounds are sodium phenyl phosphinate and sodium 2,5-dimethylphenyl phosphinate.  A long list of other suitable phosphorus compounds is given.  The desired concentration of amine end groups in the polymer may be obtained by adding an appropriate amount of a primary or secondary amine or polyamine, e.g. methylamine, ethylamine, n-propylamine, isopropylamine, hexamethylene diamine, piperazine, N-aminopentylpiperazine, N,N1-diaminopentyl-piperazine and N-aminopropyl-morpholine or, in the case of a polyamide derived from a diamine and a diacid, by using a slight excess of the diamine reactant.  The polymer may also contain at least 0,2% by weight, preferably 1-5%, of a finely divided delusterant, e.g. titanium dioxide, barium sulphate or aluminium oxide, and the light-stability of the extruded polymer may be improved by the addition of manganous hypophosphite (e.g. 0,02%).  After spinning, the phosphorus compound may be removed from the yarn by scouring with a suitable solvent, e.g. water containing soap or detergent.  Yarns obtained by the process of the invention are deeply and uniformly dyeable at a higher rate than conventional yarns, and spinning may be carried out for long periods without interruptions due to the formation of drips on the spinneret.  U.S.A. Specification 2,648,695 is referred to.

Filed: 1929-07-11
Abstract: 315,324. Westinghouse Lamp Co., (Assignees of Fredenburgh, M. N.). July 11, 1928, [Convention date]. Vacuum tubes.-In the formation of oxide coated cathodes, a mixture of crystalline barium and/or strontium and calcium carbonates is formed by simultaneous precipitation from a solution of salts of these elements, such as nitrates, by the addition of a soluble carbonate, the amount of the calcium salt being greater than 0.5, and preferably 10-20 per cent of the total anhydrous salts. During precipitation, the temperature is maintained above 85C. to produce rhombic crystals of the carbonates, and preferably a solution of normal ammonium carbonate is employed as the precipitant. In an example, 66.2 grammes of anhydrous barium nitrate, 43 of anhydrous strontium nitrate and 47.2 of calcium nitrate containing four molecules of water of crystallisation are dissolved in 960 c.c. of distilled water. To this solution, heated above 90C., is added 200 c.c. of a solution heated to 30C. and made up of normal ammonium carbonate 1100 grammes, ammonium hydrate, specific gravity 0.9, 470 c.c. and distilled water 1987 c.c., the addition being made at a constant rate over a period of one minute to limit the variation in particle size of the precipitate. After settling, the precipitate is decanted, washed with hot water until free from nitrates, excess moisture being removed by vacuum, and dried at 110C. The composition of the dry precipitate is 50 per cent barium carbonate, 30 per cent strontium carbonate and 20 per cent calcium carbonate. A suspension for coating a cathode filament in the manner described in Specification 240,252, is prepared by mixing 95 grammes of the coarse crystalline mixture, prepared as described above, with 50 c.c. of water and adding up to 5 per cent by weight of barium nitrate, or barium nitrite, and grinding the mixture in a ball mill. The coated filament is dried in a current of carbon dioxide at 700 to 900C. Specification 229,654 also is referred to.
