IPC: B29C43/22
Filed: 1928-04-20
Abstract: 289,063. I. G. Farbenindustrie Akt.- Ges. April 22, 1927, [Convention date]. Processes.-Cellulose esters of the higher fatty acids, which are insoluble in the usual organic solvents, and the soluble cellulose esters of such acids such as are prepared by the process of Specification 283,181, [Class 2 (ii), Cellulose &c.], and also the mixed esters and ether-esters, are worked up into moulded articles and shaped masses, coatings, &c. without the use of solvents or plasticising-agents, by subjection to mechanical pressure at a raised temperature, for example, at 100-150‹ C., at which the cellulose derivative becomes plastic but lower than that at which the material is liquid. Films, rods, plates, insulating bodies, floorcloth and washable carpets and cloths may be so made; and for such uses the cellulose derivatives may be mixed with cork, wood meal, mineral colours, gypsum, heavy spar, higher fatty acids or their derivatives, wax, tar and asphalt, cellulose derivatives, natural and artificial resins, phosphoric acid esters, &c. For some uses the material may be strengthened by pressing into the mass during or after the pressing operation reinforcing material such as threads, woven fabric or wire gauze. In examples, the following materials are employed -cellulose laurate, elaidic ester of cellulose, the cellulose ester of the acid from cocoanut oil, cellulose acetate-stearate, and ethylcellulose laurate. The Specification as open to inspection under Sect. 91 (3) (a) refers to the addition of phosphoric acid esters. This subject-matter does not appear in the Specification as accepted.

Title: Pipeline
IPC: G01C22/02
Filed: 1971-04-29
Abstract: 1336246 Digital displacement measurement T D WILLIAMSON Inc 29 April 1971 [12 Oct 1970] 12219/71 Heading G4H [Also in Division F2] A pipe-line pig e.g. of the kind used for inspecting the interior of pipe-lines comprises a body 5 supported within the pipe-line by cups 6, (7) (Fig. 1, not shown) and has a wheel 8 mounted thereon for rolling contact with the pipe wall. A magnet 19 secured to the wheel operates a magnetic flux responsive reed switch 20 once per revolution thereby causing a signal to pass via a low pass filter to a flip-flop the output of which drives a recorder. The number of signals produced is therefore indicative of the distance travelled by the pig. As shown the wheel 8 is supported on arm 9 pivoted at 11 and spring I biased so as to move the wheel in to contact with the pipe wall. In order to prevent the arm 9 contacting the edge of an opening in the pipe wall the axis of rotation of the wheel is prevented from extending beyond the position of the wall, e.g. by a stop such as the edge of cup 6 or by suitable dimensioning of arm and wheel. The pig is driven by fluid pressure within the pipe acting on cups 6, (7) or alternatively the body may be enlarged to substantially fill the pipe. The body 5 may be hollow to accommodate instrumentation and a recorder and a plurality of wheels may be used to ensure that at least one wheel is always in contact with the pipe wall.

Abstract: A metallic pigment composition comprises an aluminium flake pigment, a volatile hydrocarbon solvent and a surface active agent soluble in the hydrocarbon solvent for promoting dispersion of the pigment and the solvent in an aqueous medium, the surface active agent having a water solubility not greater than 2% and having surface tension characteristics such that when made up as a 0,1% solution in mineral spirits the solution exhibits an interfacial tension of not more than 12 dynes per centimetre against water. Examples of suitable wetting agents include substituted 2-oxazoline compounds, substituted 2-imidazolines, and substituted 2-triazoles, containing an alkyl or alkenyl substituent having from 12 to 22 carbon atoms.  The composition may also contain a coupling agent soluble in both the water and oil phases of the emulsion, such as an alcohol; and an auxiliary emulsifying agent such as a fatty acid soap of a volatile base e.g. ammonium stearate.  The compositions may be used in the manufacture of emulsion paints in which the film-forming agent is rubber, acrylic resin, alkyd resin, vinyl acetate resin, or styrene-butadiene resin.  Examples are given of latex paints based on the pigment composition and containing polyvinyl acetate emulsion and ethylene glycol monobutyl ether; acrylic ester resin latex and isopropyl alcohol or hexylene glycol; an alicyclic ketone resin solution, spar varnish, and ethylene glycol monobutyl ether.ALSO:A metallic pigment composition comprises an aluminium flake pigment, a volatile hydrocarbon solvent and a surface active agent soluble in the hydrocarbon solvent for promoting dispersion of the pigment and the solvent in an aqueous medium, the surface active agent having a water solubility not greater than 2% and having surface tension characteristics such that when made up as a 0.1% solution in mineral spirits the solution exhibits an interfacial tension of not more than 12 dynes per centimeter against water.

A longitudinal passage (not shown) in the stator wall leads to the outlet port. Fig. 1 shows a pump with a grooved stator in which the grooves diminish in width and depth from the inlet 12 towards each end. The rotor is mounted on ball or roller bearings and is driven from a shaft 22 passing through a packing gland 21. Alternatively the rotor may be driven by electromotor similar to that shown in Fig. 3 (Cancelled).
