Title: Improvements in tools for securing clamping devices around hose or other flexible pipes for fixing the same to connections and the like, and for similar purposes
IPC: B25B25/00
Filed: 1923-08-07
Abstract: 224,008. Riordan, J. P. P., and Murray, W. Aug. 7, 1923. Wire strainers.-A tool for tightening wires, or metal bands, on flexible tubing for securing it to a pipe connection, or the like, or for clamping a repairing patch around a pipe, comprises a pair of levers 1, 2 pivoted at 3, the lever 2 being extended to form a notched end 4. The notch 5 engages the bight 18, Fig. 5, of wire loops 17 which are passed around the pipe &c. through the bight and into holes on a slot 12 in a rotatable member 8 mounted in bearings in plates 7 secured to the lever 1. The sides of the lever 1 are curved at 6 to assist in the mounting of the member 8, and a distance piece 13 is used to space the sides of the lever 1 and from a bearing surface for the wire or band. The member 8 is formed with a tail piece 9 which engages the lever 2, and as the levers 1, 2 are moved together from the position shown in Fig. 1. the member 8 is rotated and thus bends the end of the wire 7 and holds them firmly in position, further movement of the levers 1, 2 towards each other acting to strain the wire owing to the movement of the member 8 away from the notch 5 in engagement with the bight 18. After the levers 1, 2 are brought together, thev are given a counter-clockwise movement to bend the loops over the bight 18, and the ends 17 are cut off after removal of the notch 5 from the bight, by means of a notch 15 and shearing edge 16. If a band is used bevelled cutting edges 21 are employed. The tool may be formed with a head for hammering down the ends of the wire against the pipe 19, as shown in Fig. 5.

Title: Improved cellular phenolic resin
IPC: C08J9/14
Filed: 1952-08-12
Abstract: Low density resin foams of uniform texture are made by adding an aliphatic ether, having a boiling point not in excess of 150 DEG  C., in an amount of 0.5 to 10 per cent by weight of the resin and an acid selected from hydrochloric, sulphuric, nitric, and water-soluble aromatic sulphonic acids, to a heat-hardenable liquid A-stage monohydric phenol-formaldehyde condensate containing less than 10 per cent by weight of water.  The ether may be mixed with the condensate before the acid is added, or preferably the acid and ether are mixed together and then added to the condensate.  Ageing of the acid-ether mixture at room temperature for 24 to 28 hours results in a firm uniform foamed structure.  Phosphoric acid may be added in an amount equal to the specified acids which are used in amounts of 1 to 2 per cent by weight of the neutral mixture of the resin and ether.  Ethers specified are dimethyl, diethyl, diisopropyl, n-butyl, methyl-tertiary butyl, isopropyl-tertiary butyl, methyl-isopropyl and methyl-ethyl ethers.  The liquid condensates specified are the alkaline catalysed reaction products of 1.3 to 1.6 mols. of formaldehyde with 1 mol. of a monohydric phenol, e.g. phenol, m-cresol, m-xylenol or a mixture of phenol and o-cresol. Catalysts specified are sodium, potassium, barium and ammonium hydroxides, magnesium oxide, diethylamine and ethylene diamine. In examples, liquid condensates made from phenol and formalin in the presence of (1) barium hydroxide, and (2) caustic soda, are foamed by rapidly mixing with polyethylene ether of sorbitan monopalmitate, hydrochloric acid, sodium bicarbonate and diethyl ether.  Other foams are made by using other ethers, a different acid, other esters or by omitting the bicarbonate.  U.S.A. Specification 2,446,429 is referred to.

Title: Improvements in or relating to a flow meter
IPC: G01F1/22
Filed: 1947-07-29
Abstract: 637,019. Flow-metors; fluid-pressure servo-control systems; valves actuated by magnets. PENN INDUSTRIAL INSTRUMENT CORPORATION. July 29, 1947, No. 20504. Convention date, Sept. 12, 1944. [Classes 69 (i) and 135] . A flow-meter comprises a member provided with a magnet and displaceable in accordance with the flow of a fluid, a magnetic element movable with the first member and forming in conjunction with another element a variable resistance to the flow of a second fluid and means producing a pressure which is a function of the resistance to flow provided by the magnetic element, the pressure being in excess of the pressure appearing at the variable resistance. As shown, applied to a rotameter, a venturi tube 2 has fixed therein a tapered glass tube 24 surrounded by a parallel-sided non- magnetic tube 22. A float 20 carrying a magnet slidingly fits the tube 22 and a steel ball 28 is moved within the tapered tube 24 by the movement of the float 20 and provides a resistance to the flow of air entering the tube 24 through a line 40, capillary tube 42, thimble 36 and passage 44, the lower end 34 of the tube 24 being in free communication with a tube 32 and the upper end with the atmosphere. The tube 32 is in communication with one side of a diaphragm 56, Fig. 4, the magnified movement of which is transmitted to a double piston 64 and 66 by a rod 60. Movement of the piston 66 allows more or less air to pass from an air supply PS, through passages 76, 74, 72 and 70. A pressure gauge 84 in line 70 which communicates with the capillary tube 42 is then an indication of the flow of fluid through the venturi. In a modification of the indicating means, Fig. 5 (not shown), the air supply may be fed through a constant-pressure regulating valve. In further modifications, Figs. 6 and 7, (not shown), disturbing effects due to supply pressure fluctuations may be avoided by the use of a plurality of diaphragm chambers, one of which has a floating control operated by the supply pressure.

Title: New water-soluble dyestuffs and textile colouration process
Inventor: HADDOCK NORMAN HULTON
IPC: C09B69/00
Filed: 1960-06-15
Abstract: Potassium 4-sulphophthalimide is made by heating potassium 4-sulphophthalate with urea in chlorobenzene at between 150 DEG  and 155 DEG C. for four hours.ALSO:The invention comprises water-soluble dyes of the general formula:-  <FORM:0914249/IV (b)/1> where D is the residue of an organic dyestuff devoid of sulphonic and carboxylic acid groups, m is 1 or 2, n is an integer from 1 to 4, the nucleus A may be substituted by halogen atoms and the sulpho-phthalimido methyl groups are each attached directly to an aromatic ring of radical D. Organic dyestuff residues may be of the monoazo, triphendioxazine, thioindigoid, polycyclic quinone, e.g. isodibenzanthrone, or phthalocyanine series.  The dyes are made by condensing an organic dyestuff free from sulphonic and carboxylic acid groups with paraformaldehyde and a phthalimide of the formula:-  <FORM:0914249/IV (b)/2> or an N-methylol or N-chlormethyl derivative thereof in a sulphuric acid medium.  Examples are given.  On heating the water-soluble dyes in aqueous solution with hydrazine hydrate, insoluble pigments are obtained.  The dyes colour textile materials of cellulose fibres by a dyeing process by applying a dyestuff of the above formula to the textile from a boiling aqueous dyebath with the addition of sodium sulphate or chloride and then immersing the material in aqueous hydrazine, which may also contain inorganic salts, possibly at elevated temperature, or by a printing process by applying a printing past containing an aqueous solution of the dyestuff and an unstable salt of hydrazine such as the carbonate, bicarbonate, sulphite, borate or trichloroacetate and, if desired, an acid-binder such as triethanolamine, adjuvants such as thiodiglycol and urea and thickening agents such as methyl cellulose, starch, locust bean gum and sodium alginate, followed by steaming or heating.

Title: A method of and means for indicating the progress of the combustion phenomena in furnaces
IPC: F23N5/00
Filed: 1930-07-11
Abstract: 358,578. Indicators for furnaces. JUNKERS-THERMO-TECHNIK GES. and HARTUNG, C. A., 66, Biilowstrasse, Berlin. July 11, 1930, No. 21014. [Class 51 (i).] The excess or lack of air for combustion in furnaces is instantaneously indicated by measuring the temperature in the flue or in the combustion chamber at a point at which combustion is complete and additionally influencing the temperature measuring instrument in accordance with the speed of combustion i.e. the rate of supply of fuel or of the flow of gases through the furnace. The temperature is measured by a resistance thermometer a connected to a bridge circuit c across which is connected a galvanometer b. A manometer d measuring the flow of flue gases contains a weakly conductive liquid and has in one limb two metal plates e, f connected through a battery to the bridge circuit, the plates being more or less deeply immersed according to the flow of gases. If the rate of combustion increases and the proper amount of excess air is maintained the temperature increases but the resistance between the plates e, f is also increased so that the galvanometer reading remains substantially constant. Too much excess air lowers the galvanometer reading due to both the drop in temperature and the increased resistance inserted by the manometer. Lack of air causes the manometer to cut out resistance, increasing the deflection of the galvanometer, but if combustion is incomplete the consequent reduction of temperature overcomes the effect of the manometer and the deflection is lowered. A thermocouple may be employed for measuring the temperature.
