IPC: C08K5/17
Filed: 1943-12-09
Abstract: The tensile strength of a vinyl chloride-vinylidene chloride copolymer (10-25 per cent vinylidene chloride) is increased by incorporating an amine and a heat-hardenable phenolformaldehyde type resin therewith and then subjecting the composition to heat. Preferred amines are polyalkylene polyamines such as hexamethylenetetramine.  Other amines specified are monomethyl-propylene diamine, m-phenylene diamine, di-3-amino propyl methylamine, sym.-dicyclohexyl-di-propylene triamine, mono - hexadecylamine, triethylamine, di - 3 - amino propyl ether, morpholine, piperidine, piperazine and dibenzyl amine. Phenol-formaldehyde type resins specified are cresol-formaldehyde, phenol - formaldehyde, xylenol - formaldehyde, resorcinol - formaldehyde, and phenol-furfural. The preferred temperature of heating is from 240 DEG  to 360 DEG  F. and preferred proportions are 1 to 10 per cent by weight of the amine and 2-10 per cent by weight of the phenol resin, based on the copolymer.  The heat treatment is generally continued until there is an increase in tensile strength of at least 50 per cent over that of the untreated copolymer.  An acid acceptor such as magnesium oxide, sodium carbonate and magnesium carbonate may also be present as may a plasticiser such as dibutyl sebacate, methoxy ethyl oleate, dioctyl phthalate, or tributyl phosphate. An example of the treatment using mixtures of vinyl chloride-vinylidene chloride copolymer, dibutyl sebacate, magnesium oxide, cresolformaldehyde and hexamethylene tetramine is given.

Title: Improvements in or relating to power assisted remote control systems
IPC: B64C13/00
Filed: 1947-07-30
Abstract: 634,334. Fluid-pressure servomotor-control systems. AUTOMOTIVE PRODUCTS CO., Ltd., and BRADBURY, F. J. July 30, 1947, No. 20682. [Class 135] A power assisted remote control system of the kind in which an operated member, e.g. an aircraft control surface connected at 16 to a movable cylinder 15 of a hydraulic motor device having a fixed piston 13, follows the movement of an operating member, e.g. a pilot's control connected to a link 23 itself connected through a floating lever 22 to a piston valve 18, so that actuation of the valve causes movement of the cylinder 15 which movement is transmitted by the floating lever back to the value to provide follow-up action, has annular liquid passages 35, 36 formed on the valve and provided with tapered portions to give a progressive increase in cross-section of the passages away from a cylindrical land 34 whereby the rate of flow of liquid to and from the motor device is limited so as to avoid " judder ". The angle of the tapered portions is such that the effective area upon which pressure liquid acts to operate the motor device bears a ratio to the change in the valve opening for a given axial movement thereof, this ratio being between 0.40 P.K. and 0.60 P.K. for a movement of the valve of 0.010 inch, where P represents the liquid pressure in p.s.i. and K the ratio of the relative displacement between the valve 18 and its housing to the relative displacement between the cylinder 15 and its piston 13 if the link 23 is held stationary. The system is supplied from a reservoir 28 feeding a pump 43 which delivers pressure liquid via a cut-out valve 44 to an accumulator 11 whence the liquid passes to a port 42 which is permanently in communication with the left-hand end of the cylinder 15. An exhaust port 41 is connected to the reservoir whilst a port 32, controlled by the valve, communicates with the right-hand end of the cylinder, a greater area being exposed to liquid pressure at this end of the cylinder than at the other end, so that movement of the cylinder is effected by admitting or exhausting pressure liquid to or from the right-hand end.

Abstract: 121,484. Cozette, R. J. P. E. Dec. 11, 1917, [Convention date]. Spray carburettors.-In a carburettor more especially applicable to aviation motors, the main or pure air supply is led first through a controlling valve and then through an unobstructed mixing chamber of Venturi or double cone formation into which a rich mixture is introduced at the narrowest section through a peripheral series of inlets, the said valve serving also to admit air to a series of nozzles which may be brought into action by a second valve actuated from the first. The nozzles, one of which is shown at 22, Fig. 2, are situated in a chamber 21 adjacent the float chamber 5 and deliver into conduits 11, Fig. 4, which communicate through holes 13 with the Venturi passages 2. The outlets 12, 18 from the nozzle choke tubes are controlled by a ported extension 10 of a manually-actuated valve 9 which admits air to the nozzle chamber 21 and to the Venturi passages 2 to dilute the mixture. The valve 9 is held in place by a spider 19 and is actuated by a lever 31. A second lever 34 has in its boss 33 an air hole 32, and by adjusting this lever the time at which air may be admitted through the tube 30, Fig. 4, to provide an altitude correction may be varied. The Venturi passages 2 are jacketed at 15. The float levers are positively connected to the float 6. The float chamber communicates through a hole 28 with the chamber 21, excess fuel in which may be drained away at 29. Fuel enters at 3 and is filtered at 4. One of the mixing chambers 2 is omitted when the carburettor supplies a single cylinder or several cylinders arranged in a single line.
