Title: Improvements in circuit arrangements for controlling the frequency of an oscillator
Inventor: LAX LADISLAV
IPC: H03J7/04
Filed: 1953-02-19
Abstract: 745,831. Automatic frequency-control systems. PYE, Ltd. Feb. 18, 1954 [Feb. 19,1953], No. 4674/53. Class 38 (4). For controlling the frequency of a non- sinusoidal oscillator 6 a discriminator comprising two band-pass filters 1, 4, is used, the first covering a frequency band 0-f outside, e.g. just below, the fundamental frequency f0 to which the oscillator 6 is to be tuned or a frequency f0 related to the correct oscillator frequency, and the second an adjacent frequency band including the frequency f0 extending, e.g., from just below #1 to #2. Further it is arranged that an output from the first filter 1 energizes a relay 2b, 2a (from the unenergized position shown) so that a motor 3 is energized from an A.C. source to drive a tuning condenser 6a of the oscillator to correct the frequency in one direction, and that no output from either filter 1, 4 produces a reversal of the motor 3 and correction of the tuning in the opposite direction, and that on an output being derived from only the second filter 4, opening relay 5a, the motor tuning control is stopped. The oscillator frequency may be beat with a constant frequency source 10a and/or frequencymultiplied or divided to derive a related frequency fr applied to both the.filters. Further, the output of filter 4, which disables the motor 3, may also be applied to a discriminator 8 along with an output from a standard source 7 tuned to the correct oscillator or related frequency fr so that an output is obtained applied to a reactance valve 9 for fine control of the oscillator frequency. A switch 5b ganged with the switch 5a ensures that the reactance valve is connected to the oscillator only during the range #1-#2 of the filter 4. Preferably f2 is less than twice #1 so that the output of filter 4 is sinusoidal.

Title: Improvements in or relating to the protection of aluminium and its alloys against corrosion
IPC: C23F11/10
Filed: 1954-02-17
Abstract: A method of preventing or minimizing corrosion or corrosion and rubbing on aluminium or aluminium alloy surfaces comprises applying to the surface, either simultaneously or separately, substances that together form a penetrated monolayer by sensitized adsorption A penetrated monolayer is a monomolecular layer of a weakly polar amphipathic substance which has adsorbed a more strongly polar amphipathic substance.  Sensitized adsorption is the adsorption of such a strongly polar substance (the sensitizer) by a metal surface to facilitate the subsequent adsorption by the surface of the weakly polar substance.  An amphipathic substance is one whose molecules contain a polar portion and a non-polar portion.  The surfaces, which may be anodized, are treated with the sensitizer, examples of which are aryl or alkyl sulphates, sulphonates, phosphates, or phosphonates or salts of fatty acids, and the second compound is an alkyl or aryl alcohol, or cholesterol.  The compounds may be applied to the surface simultaneously as an oil-water emulsion, e.g. sodium dodecyl sulphate in water and cholesterol in B.P. paraffin, or separately by successive treatments e.g. with a solution of lanoline in white spirit of B.P. paraffin and sodium alkyl sulphonate in water.  The surface may be stoved at 120 DEG F. between the lanoline and sulphonate treatments.  Various combinations of pairs of the above compounds are described with various degrees of heating between 74 DEG F. and 80 DEG C.  A specific sensitizer mentioned is sodium lauryl sulphate in water.

Filed: 1956-02-16
Abstract: Liquid detergent compositions comprise, by weight, (a) 2-30 per cent, preferably 5-15 per cent, of the benzyl ether of octylphenoxypolyethenoxyethanol containing 12-30, preferably 16, ethenoxy units, either (b) 1-10 per cent, preferably 3-7 per cent, of the sodium, potassium, or ammonium salt of methylene bis-(naphthalene sulphonic acid), or (c) 0.5-15 per cent, preferably 0.5-3 per cent, of the sodium, potassium, or ammonium salt of one or more fatty acids containing 12-18 carbon atoms, or both (b) and (c), and (d) water to make up 100 per cent.  The compositions may additionally contain up to 10 per cent, preferably 2-7 per cent, of tetrapotassium polyphosphate and up to 10 per cent, preferably 3-7 per cent, of one or more octylphenoxypolyethenoxyethanols containing 7-20, preferably 7.5-9.7, ethenoxy units.  The compositions are said to be of particular use in dishwashing machines.ALSO:The benzyl ethers of octylphenoxy-polyethenoxyethanols containing 12-30 ethenoxy groups are prepared by reacting the appropriate octylphenoxypolyethenoxyethanol in an atmosphere of nitrogen and in an inert solvent, such as benzene, toluene, or xylene, with benzyl chloride or bromide in the presence of a strong base, for example an alkali or alkaline-earth metal hydroxide or an alkali-metal lower alkoxide, at a temperature of 50-200 DEG  C., preferably 100-150 DEG C.  Details are given of the preparation of the ether containing 15 ethenoxy groups, wherein the appropriate condensate is mixed at 100 DEG  C. with sodium hydroxide in an atmosphere of nitrogen until all the hydroxide has dissolved.  Benzyl chloride is then gradually introduced, after which the reaction mixture is maintained at 100-110 DEG  C. for 3 hours.  Toluene and water are then added and the mixture boiled, after which it is allowed to separate into 2 layers. The upper layer is steam stripped to remove toluene, benzyl chloride, and benzyl alcohol, and the remaining required product dried at 100 DEG  C. and 2 mm. pressure, and finally filtered.

Abstract: 1343296 Branch pipe couplings; valves COMPAGNIE FRANCAISE DES PETROLES 19 April 1971 [3 March 1970] 4903/73 Divided out of 1343294 Headings F2G and F2V An injector for injecting fluid fire extinguishant into a stream of fluid fuel in a conduit, e.g. an oil-well head pipe, comprises needle valve member 25 urged by spring 31 on to seat 32, chamber 34 surrounding needle 25 upstream of seat 32 into which ducts 35 conduct the extinguishant tangentially to the walls, and an hydraulic circuit including piston 19 subject to the pressure in the conduit and operable to exert a force on needle 25 in the same direction as spring 31 and proportional to the conduit pressure. The injector 2 has threaded ring 13 screwed into recess 14 in a bore in tube 1. Cylindrical element 15 is mounted in ring 13 and leaves passage 16 for extinguishant introduced into chamber 6, seal 17 sealing off 16 from the interior of 1. Cylinder 15 houses element 18 having two bores, the first receiving end part 19a of piston 19, and the second a layer part 19b. Piston end 19c which is larger again moves in a bore in 15 containing hydraulic fluid. Seals 20, 21, isolate the hydraulic fluid from the fuel. Ducts 22, 23 supply the hydraulic fluid to chamber 24 behind valve needle 25, bolts 26, 27 with seals 29, 30 closing duct 23 and chamber 24 and permitting introduction and drainage of the fluid. Ducts 35 connect chamber 34 to passage 16 and extinguishant supply. If flame occurs in body 1 a pressure prevails therein whereas chamber 6 is not under pressure; piston 19 therefore communicates a proportional force to face 49 of valve 25, augmenting that applied by the spring, and member 25 bears harder on seat 32. If the extinguishant pressure in 6 increases while the oil pressure is constant, the pressure in chamber 34 exerts an opposing force on valve needle 25; when it exceeds that exerted by the spring and hydraulic fluid, valve 25 is lifted from seat 32 and the extinguishant flows into the oil conduit. The injector provides a spray jet with high axial impetus.
