Title: Fluid control device for sensing rate of rotation
IPC: G01C19/14
Filed: 1963-02-06
Abstract: 1,037,531. Pure fluid amplifiers. R. E. BOWLES. Feb. 6,1963 [Feb. 6, 1962], No. 4934/63. Heading G3H. [Also in Division G1] A fluid vortex amplifier for measuring angular rate of rotation comprises a vortex chamber 23, Fig. 2 formed from plates 14,16 and an annular plate 17. A porous wall 18 is arranged in the chamber and fluid is supplied to the gap 22 between the members 17,18 and normally passes through the wall 18 as a radial flow to axial outlets 26, 27. When the amplifier rotates, vertical flow is induced in the chamber and an Archimedes type screw 29 directs more fluid to one of the outlets 26, 27 than the other depending upon the direction of flow. The pressure differential in the outlets is a measure of the rate of rotation and there pressures are fed as control signals to a fluid amplifier whose outputs are connected to opposed bellows which carry an indicator as in Fig. 5 (not shown). In a modification, tangential jets may be applied to the chamber to control the output and to eliminate the delay caused by the time of travel of the fluid through the chamber. Figs. 8-10 and 19-21 (not shown) show alternative scoop arrangements which may be used in place of the Archimedes screw. Fig. 15 shows one form of amplifier which while providing a differential pressure at the outlets 138,142 in response to rate of rotation as above, also provides an integral of this value by pressure pick off passages 146-154 which produce values of the static pressure at radial spaced positions in the vortex chamber. The signals may be combined with the rate signals if required as control signals of the fluid amplifier. In a modification, the top and bottom walls of the vortex chamber are porous and provide an average pressure of the pressure differences across the chamber. In a further modification Fig. 18 (not shown) the annular porous wall has orifices to direct a jet to the central outlets which is equivalent to the integral signal above while the jet is also affected by the remaining flow through the porous wall to provide a combined rate and integral output signal.

Title: Method for preshrinking crystalline vinylidene chloride copolymer film
IPC: B29D7/00
Filed: 1952-03-03
Abstract: Film of oriented crystalline vinylidene chloride copolymer is treated to prevent heat shrinking by passing it over four smooth rollers, at least the second and third of which are independently heated to a temperature between 200 DEG  F. and 265 DEG  F., the temperature of the first roller being below 185 DEG  F. and that of the fourth roller up to 240 DEG  F. but below that of the second and third rollers, and the total contact time between the film and the heated surfaces being between 1.5 and 20 seconds.  The film is maintained under sufficient tension to keep it wrinkle-free but insufficient to stretch it.  As the film shrinks during treatment, the third and fourth rollers may be driven at speeds down to 85 per cent. of those of the first and second rollers.  After the treatment, the film has a shrinkage of less than 5 per cent. in either major dimension when subjected to a temperature of 212 DEG  F. for 10 minutes.

Title: Aryl phosphates
IPC: C07F9/12
Filed: 1961-02-15
Abstract: The invention comprises an aryl phosphate having a kinematic viscosity of at least 300 SUS at 100 DEG F. and consisting of a phosphoric acid ester of a phenolic mixture, e.g. a cresylic acid, at least 40% by weight of which is 2, 4-dimethyl phenol and/or 2, 5-dimethyl phenol and/or 3, 4-dimethyl phenol, the dimethyl phenol or dimethyl phenol present exceeding by at least 40% by weight of the phenolic mixture the amount of any meta- and para-cresols present. Other phenols which may be present in the phenolic mixture used to form the aryl phosphates are o-cresol, 2-, 3- and 4-ethyl phenols, 2, 3-, 3, 5-, and 2,6-dimethyl phenols, 2, 4, 6- and 2, 3, 6-trimethyl phenols and other 9 carbon phenols The aryl phosphates may be obtained by reacting the phenolic mixture at elevated temperature with a suitable ester-forming phosphorus compound e.g. a phosphoryl halide such as phosphorus oxychloride, phosphorus pentachloride or phosphorus pentoxide.  A 5 to 8% weight excess of the phenolic mixture above that required for the reaction is generally employed and when phosphorus oxychloride is used the reaction mixture is preferably heated slowly to a maximum temperature of about 195 DEG C. in the presence of a small amount of metal halide catalyst e.g. aluminium chloride or magnesium chloride for 6 to 10 hours.  The aryl phosphate may be recovered by extracting the crude product with weak aqueous alkali to remove acidity and excess phenols followed by treatment with an oxidizing agent to remove the oxidizable impurities. Alternatively the aryl phosphate may be recovered by distilling the crude product at reduced pressure to separate a main portion which is then extracted with weak aqueous alkali and treated with an oxidizing agent e.g. potassium permanganate.  The products are useful as hydraulic fluids, as lubricants, and as plasticizers for thermoplastic materials e.g. polyvinyl chloride and cellulosic plastics (see Division C3).ALSO:A thermoplastic material, e.g. polyvinyl chloride or a cellulose ester such as cellulose acetate, propionate, acetate propionate or acetate butyrate or a cellulose ether such as ethyl cellulose is plasticized with an aryl phosphate having a kinematic viscosity of at least 300 SUS at 100 DEG F. and consisting of a phosphoric acid ester of a phenolic mixture, e.g. a cresylic acid, at least 40% by weight of which is 2, 4-dimethyl phenol and/or 2, 5-dimethyl phenol and/or 3, 4-dimethyl phenol, the dimethyl phenol or dimethyl phenols present exceeding by at least 40% by weight of the phenolic mixture the amount of any meta- and para-cresols present (see Division C2).  Other plasticizers may also be present.

Title: Apparatus for the cavitation treatment of liquids
IPC: B01F5/10
Filed: 1952-03-04
Abstract: Apparatus for the cavitation treatment of liquids comprises a vessel 2 containing a rapidly-revolving rotor 4 provided on its circumference with a ring of separated nozzles 32 through which liquid is sprayed in separate jets against a circumferential stator 6 having a plurality of centrifugal passageways, and is characterised in that the stator comprises a plurality of blades arranged so that each of the blades is slidingly contacted on only one side by the jets, and that the plane of said side is substantially vertical to the plane of rotation of the rotor and at an angle to the direction <PICT:0702811/III/1> of impact of the jets.  The blades are caused to vibrate by the impingement of the jets, and the liquid flows as a film over the surface of the blades and is dissipated into small particles; the liquid becomes charged with the gas present between the rotor and the stator.  The effect may be intensified by roughening the surface of the blades, e.g. by sand-blasting.  Liquid is continuously sucked from the vessel 2 through tube 5, connected to the rotor and provided with a stirrer 7, and returned to the vessel. Pump 8 circulates liquid through pipe 10, filter 21, pipe 10a, mixer 13, and nozzle 12, back to the vessel 2; nozzle 12 also serves for starting the circulation through the rotor.  Fresh components are introduced at 22, 23, 24, and the product is removed at 14, passing through a settling tank 16 from which separated fractions may be returned to the main circuit at 31. The rotor may be provided internally with rows of pins and staggered plates to prevent centrifugal separation of the components; alternatively a narow tapering duct may lead to each nozzle.  Emulsification and dispersion may be effected and reactions between liquids, liquids and gases, and liquids and solids (e.g. catalysts) may be initiated.
