Title: Improvements in fluid valves
IPC: F16K27/08
Filed: 1952-05-29
Abstract: 742,579. Screw-actuated slide valves. SMITH & SONS (NOTTINGHAM), Ltd., S., and BROWN, F. Aug. 28, 1953 [May 29, 1952], No. 13627/52. Class 135. A screw-actuated slide valve comprises a valve body 1, Fig. 1, closed at its lower end and having a bore 3 extending upwardly to an open mouth to receive a metal neck ring 119, resilient packing rings and a gland 18 which surround a valve-operating spindle 5 carrying telescopic valve parts 34, 35 urged apart by a spring into contact with hardened seating surfaces 25, 26 formed on the ends of inlet and outlet ducts 32, 33 welded to the valve body. The body 1 is formed with a flange 2 to which the gland 18 is secured and which supports pillars 7, 8 mounting a bridge-piece 11 having a screw-threaded bore engageable with a screw-threaded sleeve 13 which mounts a hand wheel 14 and cooperates with screw-threads 12 on the spindle 5. The screw-threads between the bridge-piece and the sleeve and those between the sleeve and the spindle are of opposite hand permitting controlled movement of the sleeve in the same direction as the spindle and comparatively quick operation of the valve. A cross-bar 16 engaging the pillars 7, 8 prevents rotation of the spindle 5. The valve is dismantled for servicing by removing the gland and bridge nuts rotating the hand wheel in a valve-closing direction to raise the bridge-piece 11 which is then supported on the pillars and then rotating the hand wheel in a valve-opening direction whence the valve, packing, &c. may be removed. Sight holes 39 drilled through the bridge-piece 11, sleeve 13 and spindle 5 ensure correct reassembly of the valve parts. A suitablyworded instruction plate may be fitted to the bridge-piece.

Title: Improvements in or relating to radio direction finding
IPC: G01S3/12
Filed: 1938-05-07
Abstract: 517,862. Directive wireless signalling. CLEVELAND, F. J. (Bendix Aviation Corporation). May 7, 1938, No. 13699. [Class 40 (v)] The pick-up voltage from a frame aerial 5 is fed to one grid, and that from a non-directional aerial 16 to the other grid of a dual valve 3, 4, and the combined output is fed to a common receiver 41, the arrangement being such that either an omni-directional, bilateral (figure-of-eight) or uni-lateral (cardioid) response is obtained according to the setting of control switches which render one or other of the sections 3, 4 of the combining valve ineffective. Switches 14, 15 control the tuning of the aerial 5 and are ganged with switches 23, 24 which short-circuit the anode resistance 21 and cathode resistance 33, respectively. A switch 19 regulates the phasing-resistance 17 of the aerial 16, and is ganged with a switch 30 controlling the grid-bias on the section 4 of the dual valve. A similar switch 29 serves to control the grid-bias on the section 3 of the same valve. In operation, a signal is first picked up on the non-directional aerial 16 alone, the " directional " section 3 of the valve being paralysed. The signal is next tuned in on the frame aerial 5 alone, and bearings are taken on this setting. Or the pick-up from both aerials can be combined and balanced to produce a cardioid curve to remove the 180‹ ambiguity. It is stated that quadrantal error can be allowed for by shifting the position of the indicator scale to give a zero reading on a transmitter known to be directly in the fore- and-aft line of the craft being navigated. A part of the indicator scale is masked, to avoid the 180‹ ambiguity, as described in the Specification 517,861.

Patent GB-688555-A (GB)
Title: Improvements in or relating to the preparation of acetals
IPC: C07C43/30
Filed: 1950-06-07
Abstract: Methyl or ethyl acetals of esters are prepared by reacting at a pressure of 1000 to 4000 lbs./sq.in. and at a temperature of 80 DEG to 200 DEG  C., a mixture of carbon monoxide, hydrogen, methanol or ethanol and an ester having the general formula RCOOR1, in which R represents a monovalent, aliphatic hydrocarbon radical of 2 to 21 carbon atoms containing one double bond as the sole unsaturation therein and R1 is a monovalent hydrocarbon which is free of non-benzenoid unsaturation and which contains 1 to 12 carbon atoms, in the presence of 0.001 to 0.05 mole per cent, based on the ester, of a dissolved cobalt catalyst consisting of cobalt carbonyl or organic carboxylic acid salts of cobalt which are free of non-benzenoid unsaturation and which are soluble in the said mixture and separating the resultant acetal from the reaction mixture.  The acetal-ester results from addition of a hydrogen atom to one carbon atom joined by the double bond and a group -CH(OCH3)2 or -CH(OC2H5)2 to the other carbon atom so joined. Preferably a carbon monoxide-hydrogen ratio of 2 : 1 to 1 : 2 is used while an excess of either the alcohol or olefinic ester may be present.  Inert solvents such as benzene or toluene may be employed.  The acetal-esters may be converted to the corresponding aldehydo-esters by splitting under acidic conditions.  In examples: (1) an equimolecular mixture of hydrogen and carbon-monoxide is fed into an autoclave containing ethyl acrylate, methanol and cobalt di-2-ethyl hexoate at 100 DEG  C. and 3000 lbs. pressure for one hour yielding ethyl-gamma, gamma-dimethoxy butyrate with ethyl gamma-oxybutyrate as impurity; (2) methyl methacrylate is similarly converted into methyl alpha - methyl - gamma, gamma - di - methoxy butyrate; (3) a mixture of methyl oleate, methanol and a solution of cobalt carbonyl in benzene is similarly reacted with carbon monoxide and hydrogen yielding a mixture of methyl 9-dimethoxy methyl stearate and methyl 10-dimethoxy methyl stearate; in these examples similar results are obtained by replacing methanol by ethanol.  Esters of crotonic, vinyl acetic, beta-ethyl acrylic, allyl acetic, hydrosorbic, isohydrosorbic, decenoic, undecylenic, myristolenic, palmitolenic, oleic, erucic and brassidic acids may also be used; the alcoholic radicals of such esters may be methyl, ethyl, isobutyl, tert.-amyl, 2-ethylhexyl, di-isobutyl, lauryl, benzyl and p-butylphenyl groups including their isomeric groups.  Further examples of cobalt salt catalysts are those of caproic, caprylic, capric, lauric, myristic, palmitic, margaric, stearic, arachidic, behenic, phenyl acetic, b -phenyl propionic, biphenylacetic, p-tert.-butyl phenyl acetic acid, p-ethyl phenyl propionic acid, naphthenic acids and the carboxylic acids described in Specifications 363,394, 413,728, 414,121 and 451,053.
