Title: Improvements in or relating to pressure-sensitive adhesive tape, and method of producing same
IPC: C09J7/21
Filed: 1946-10-01
Abstract: Coating compositions comprise an alcohol-soluble urea-, thiourea- or melamine-aldehydemonohydric alcohol resin and a plasticizer therefor such as a castor oil-modified alkyd resin or heavy-bodied castor oil; optionally, ethyl cellulose, polyvinyl butyral, dipentamethylene thiuram tetrasulphide, fillers, e.g. zinc oxide, volatile solvents such as xylol, butanol, ethyl alcohol, pigments or dyes may be incorporated in the compositions. When the coating compositions are applied to fibrous sheet materials, the sheet material may be impregnated with a composition comprising one or more of the following resins: rosin, ester gum, polymerized rosin, zinc abietate, limed rosin, hydrogenated rosin, pentaerythritol abietate, coumarone-indene, hydrogenated coumarone - indene, depolymerized butadienestyrene copolymer, together with vulcanizing agents and accelerators such as zinc oxide, dipentamethylene or pentamethylene thiuram tetrasulphide, oil-soluble phenol-aldehyde resins, alkyl phenol sulphide dispersed in oleum spirits and tetramethyl-thiuram-disulphide.  The depolymerized butadiene-styrene copolymers may be made by mixing the copolymer with p-hydroxy-phenyl-morpholine, zinc oxide and zinc xylyl mercaptan, and heating the mixture with steam under pressure.  If desired, the zinc xylyl mercaptan may be replaced by phenol hydrazine.  The castor oil-modified alkyd resin may be made by heating together (1) ethylene glycol, glycerine, castor oil and an addition product of a terpene and maleic anhydride; (2) ethylene glycol, phthalic anhydride, glycerine and castor oil.  The compositions are used in the preparation of pressure-sensitive adhesive tapes.

IPC: F24D5/10
Filed: 1929-09-30
Abstract: 333,786. Carrier-Ross Engineering Co., Ltd., and Ward, S. Sept.30, 1929. Forced ventilation; ventilating conduits, arrangements and adaptations of.-In a method of exhausting moisture laden air from an enclosure such as a laundry or from dyeing or paper-making machinery, heat is radiated to the air in the enclosure to raise it above dew point temperature, and warm dry air is mixed with the air being exhausted in such quantity as to prevent condensation in the system. Warm dry air from a heater 11 is forced by a fan 9 along a duct 3 formed over a slot 7 in an outer plate 1, and passes between the plate 1 and an inner plate. 2 suspended from the supply duct 3 by angle members 8. This warm air heats the plate 2 which in turn radiates heat to the air in the enclosure. Ducts 4 of scroll form extend along each side of the plate 1 and are connected by a breeches piece 13 to a fan 14 which exhausts air from the enclosure by way of slots 6 formed between the ducts 4 and depending side walls 5. Before entering the slots 6, the moist air heated by radiation is mixed with the warm dry air in the space B. The apparatus may be in the form of a hood over a single machine or over the whole room; or, alternatively the ceiling and walls of the enclosure may form the outer plate and the depending walls. In a further modification the outer and inner plates may be vertical and the ceiling and floor of the enclosure then take the place of the side walls.

Abstract: 447,474. Producing electric oscillations. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and KEALL, O. E., 32, Rainsford Avenue, Chelmsford, Essex. Oct. 19, 1934, No. 30050. [Class 40 (v)] To double a frequency constituted by a modulation of a carrier wave, the wave is passed in parallel through two channels, one including a detector and the other not, the detected output being modulated on the output from the other channel in phase opposition with the modulation already present in that channel. As shown, one channel includes an amplifier C2, detector D1, and a valve E2, forming part of a series modulator E1, E2. The other channel comprises an amplifier B2, and the valve E1 of the modulator. The output of the valve E1 comprises the original carrier modulated by twice the original modulation frequency. It can be utilized as a modulated carrier and applied to further similar stages, or it may be rectified at F and the doubled frequency utilized. The system may be used to control the frequency of a number of broadcast transmitters from a centrallysituated master-frequency oscillator controlled by a tuning-fork or similar device.
