Abstract: Coloured copolymers used in the sizing of textile materials comprise (a) 72 parts of ethyl acrylate, 10 parts of acrylamide, 7 parts of acrylic acid, 5 parts of methyl methacrylate and 6 parts of a dye having the formula <FORM:1072878/C3/1> which has been neutralized with caustic soda solution or (b) 70 parts of ethyl acrylate, 7 parts of methyl acrylate, 10 parts of acrylamide, 7 parts of acrylic acid and 6 parts of a dye having the formula <FORM:1072878/C3/2> which has been neutralized with caustic soda solution, the parts being by weight.ALSO:Yarns, filaments and threads of all types, e.g. of viscose rayon, cellulose acetate, polyesters, cotton, wool, polypropylene or polyacrylonitrile, are sized with a water-soluble film forming addition polymer which is combined with a dye by a covalent bond. Solubility in water is defined as the ability to form true or colloidal solutions with water.  The coloured polymers which may subsequently be removed by washing may be water-soluble copolymers of olefinically unsaturated polymerisable colourless compounds and dyes bearing vinyl groups or water-soluble homopolymers or copolymers of olefinically unsaturated polymerisable colourless compounds which by virtue of reactive groups are combined with dyes which bear reactive groups.  Water soluble copolymers prepared from (a) azo dyes or anthraquinone dyes which bear a vinyl group, of which numerous examples are given, as the coloured monomers, (b) water soluble monomers, e.g. acrylic, methacrylic, maleic or fumaric acids or their alkali metal or ammonium salts or amides, N-vinyl pyrrolidone, vinyl ethers, and 2-vinyl pyridine, N-vinyl-imidazole and 2-aminoethyl acrylate and salts and quaternisation products thereof, and optionally (c) monomers which form water-insoluble homopolymers, e.g. esters of acrylic, methacrylic, maleic or fumaric acid, acrylonitrile, vinyl esters, p  vinyl or vinylidene chloride, styrene, butadiene, ethylene and propylene, may be used, the proportion of coloured monomer preferably being 1-8% by weight. Alternatively the coloured polymer may be prepared from a polymer formed from monomers which bear reactive groups which do not react under the conditions of the polymerisation, e.g. monomers having methylolamide groups and lower ethers thereof such as N-methylol acrylamide, and dyes bearing complementary reactive groups, e.g. carbamoyl groups or chlorine atoms, examples of which are given.  The term "dye" is intended to include compounds which are exclusively or mainly absorbent and fluorescent in ultra-violet light.

Abstract: 1,009,394. Space-charge wave tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 2, 1962 [Oct. 4, 1961], No. 37354/62. Heading H1D. In an electron-beam tube for parametric amplification the electron gun, which has a plurality of anodes, is arranged to retard the electron beam when subjected to a magnetic focusing field of different strength from that in the region of beam-couplers and thereby to expand the beam cross-section within the gun to reduce noise. The effect is achieved by applying particular voltages to the six anodes of the gun and examples are given in the Specification. The gun may be of conventional construction, employing Brillouin focusing, otherwise the necessary change in magnetic field is achieved by surrounding the cathode 51 with a ring 65 of ferromagnetic material, supported between ceramic spacers. The tube is of quadruple type of known construction, the signal couplers comprising parallel plates (Fig. 1, not shown) or cavities. It is stated that the noise suppression obtained is effective for both the fast and slow waves.

A hydraulic vibrator comprises a reciprocating piston 17 controlling inlet and outlet parts 13, 14 in the cylinder 11, the connections to the working chambers 24, 25 being reversed as the piston passes its mid stroke position, and the effect of the pressure change in the chambers being delayed by accummulators connected to the chambers, so that the piston overshoots its mid stroke position and reciprocation is maintained. As shown, the accummulators comprise chambers on either side of a shuttle 32 which engages fixed stop 33 or adjustable stop 34 according to which working chamber is pressurized. Stop 34 is adjusted to adjust the frequency and hence amplitude of reciprocation. An adjustable restrictor also may be provided in the high pressure pipe 15 to control the frequency. The high and low pressure connections 15, 16 may be provided in the piston instead of the cylinder, passages 26, 27 then being in the cylinder.

Abstract: 1446721 Utilizing underground strata W B HARRIS R R DAVISON and W D MORSE 15 Aug 1974 [15 Aug 1973] 38655/73 Heading F4U A method for collecting and storing hot or cold water in underground strata during summer and winter months, respectively, and making the same available for heating during winter months or for cooling during summer months, comprises the steps of heating or cooling the water, passing the hot or cold water to the underground strata for storage, removing the hot or cold water from the strata as required, removing the heat or cold from the water, and returning the warm or cool water back to the underground strata. Preferably, the water is returned to a single underground statum or aquifer in two separate zones, recirculation ducts 8, 20 being provided. For cooling a building in summer, a pond 1 is preferably the winter source of cold water. For heating a building in winter, a solar heater 10 is provided for heating the water during the summer months. However on fine winder days, the solar heater may be utilized to add heat to the water in the system. In this instance, the warm water returning from the building is directed to the heater 10 via a pipe-line 17 for partial reheating before being returned to the warm zone 15 by means of a pipe-line 18. On particularly sunny winter days the water might be sufficiently reheated to be recycled directly by piping 19 to the buildings rather than using the stored hot water.
