Abstract: 1536114 Doppler beacon OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 8 July 1977 [9 July 1976] 28870/77 Heading H4A An aerial system, for simulating a Doppler navigational beacon of the type having dipole pairs a1, a1<SP>1</SP> &c. which are commutated to give the effect of rotation, comprises dipole pairs 1,1<SP>1</SP> &c. the two dipoles of each pair being spaced in a common direction. The spacing differs from pair to pair and is given by the projection of points a1, a2 &c. of circle 106 on to a plane. The pairs are commutated such that the spacing effectively varies as a sinusoidal function of time, the power fed to the dipoles being weighted proportionally to the spacing. The two dipoles of a pair are fed #/4 out of phase. Random positioning of the centres 1<SP>11</SP>, 2<SP>11</SP> &c. of the pairs enables an aircraft receiver to discriminate against multi-path interference by a signal correlation technique.

Title: Manufacture of cyclohexylamines
Filed: 1926-11-18
Abstract: 261,764. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). Nov. 19, 1925, [Convention date]. Cyclohexylamines are produced by subjecting primary or secondary amines to reaction with halogen cyclohexanes, preferably in the presence of a catalyst or an acid binding agent. In examples, (1) bromocyclohexane (1 mol.) or chlorocyclohexane and aniline (2 mols.) are boiled together with a little copper. On cooling, acidification with hydrochloric acid precipitates the hydrochloride of monocyclohexylaniline. Toluidine, naphthylamine, chloraniline, monomethylaniline, diphenylamine, and carbazole may be used in a similar manner. By using 2 molecular proportions of bromocyclohexane with the addition of 1 molecular proportion of sodium acetate, a dicyclohexylaniline can be produced : (2) Bromocyclohexane is introduced drop by drop into heated aniline, and on cooling, aniline hydrobromide separates and is filtered, the filtrate giving cyclohexylaniline when made alkaline with aqueous alkali : (3) o-Bromomethylcyclohexane is introduced into aniline, the product being methylcyclohexylaniline : (4) Bromocyclohexane is introduced into heated monoethylaniline. the product being cyclahexylethylaniline, and the methyl derivative may be obtained in the same way using metlylaniline : (5) A mixture of alpha-aminoanthraquinone, bromocyclohexane, nitrobenzene and a little copper powder is heated, a dark condensation product separates which dissolves in concentrated sulphuric acid and, on pouring this solution into water, the new product is precipitated as brown flakes; #-aminoanthraquinone, 1:4- aminonhloavanthraquinone, a diaminoanthraquinone or the like may be used similarly.

Title: Improved combination of reciprocating engine and exhaust steam turbine
IPC: F01D15/02
Filed: 1928-10-11
Abstract: 298,613. Wach, H. Oct. 12, 1927, [Convention date]. Addition to 264,359. Stop-gear; driving arrangements for screw propellers.-Relates to reciprocating engines coupled with exhaust steam turbines, the latter having releasable couplings and consists in modifying the interacting controls of the parent Specification, (a) by inserting a valve in the oil pressure system which is operated by the exhaust steam valve and in turn controls the fluid coupling, and (b) by inserting a governor device in the oil-pressure system which modifies the vacuum in the condenser, and closes the exhaust steam valve. As shown, the control 16 of the reciprocating steam engine is in position for reverse running ard has moved the oil distributing-valve 3 so that the oil pump 8 passes oil through the pressure line 12 above the steam valve 1 to force it down into the position whereby steam is cut off from the turbine and directed to the condenser. Downward movement of the valve 1 results in the valve 5 being raised whereby pressure oil passes through the pipe 10 to the back of the regulating-plungers 6 while the other side is opened to the discharge pipe 11 and the resultant movement of the plungers 6 opens the discharge outlets 7 of the fluid coupling 2 whereby the turbine drive is disconnected. On the speed of the turbine becoming excessive, the member 17 actuates a trip on the valve 18 whereby the latter is raised by its spring and connects the pressure oil by the pipes 20, 14, direct with the reservoir and the pressure of the oil is reduced so that the exhaust steam valve 1 is now closed by its spring and the turbine is shut off. At the same time, a valve at the bottom of the valve 18 controls an air supply through the pipe 22 and valve 19 to the condenser to modify its vacuum. In a modification, rotary control valves are used in place of the plunger velves in the oil system.

Patent GB-603927-A (GB)
Title: Improvements in primary galvanic cells
IPC: H01M50/463
Filed: 1945-11-06
Abstract: A film for use in dry batteries consists of an alkyl cellulose or vinyl polymer one or both surfaces of which have been rendered insoluble.  Alternatively the soluble film may be backed by an insoluble film, a film of alkyl cellulose ether such as methyl cellulose, for example, being backed by a film of regenerated cellulose.  A methyl cellulose film may be made insoluble by the addition of polybasic acids, aliphatic or aromatic carboxylic acids or phenol carboxylic acids or by means of citric, phthalic, tartaric and malic acids, or tannic acids such as gallic or digallic acid.  A film made from soluble methyl cellulose may be prepared by treating one surface with a tannic acid solution which may be poured, sprayed or wiped on the surface.  An insoluble diaphragm may be prepared from a methyl cellulose solution containing tannic or citric acid. Substances other than methyl cellulose may be used such as hydroxyethyl cellulose, salts of the cellulose ethers of glycollic acid such as sodium carboxymethyl cellulose, polyvinyl alcohol, polyvinyl partial acetals or partially hydrolyzed polyvinyl acetate and they may be rendered insoluble by treatment with aldehydes such as glyoxal and formaldehyde, aldehyde resins such as phenol formaldehyde, amide condensation products such as urea, and isocyanates.  Films of sodium carboxymethyl cellulose and polyvinyl alcohol may be rendered insoluble by heat.

The -steam passage from the boiler includes a filtering portion F containing wire gauze or braid, throttling portions H and the distributing portions J. The throttling portions H are formed .solely in the cover plate and are of smaller crosssection than the portions J so as to build up back pressure in the boiler to control the flow of water into the boiler. Water drips into the boiler C from a reservoir (not shown) and a baffle E prevents droplets being thrown out of the boiler. The boiler has a deeper portion C<SP>2</SP> which is the same depth as the filtering portion F.

A gas centrifuge for the separation of isotopes comprises a rotatable drum 8 disposed in a casing 7 to provide a clearance 18, an aperture 15 in the drum for the supply of the gases, outlets 11 permitting separated fractions to pass independently into the clearance, and means for minimising mixing of the separated fractions with each other and with the supply of gas. Gas from a container 6 is fed to a first separator which discharges heavier and lighter fractions to a container 5 and a second separator respectively. The second separator discharges heavier and lighter fractions to the first and third separators respectively. The third separator discharges the lighter fraction to a collector 4, and the heavier fraction to the second separator. In the first separator the clearance between the fractions is connected to the low pressure part of the drum, in the second separator pumps 21 are embodied at either end of the drum, and in the third separator the clearance at the ends of the drum is decreased. In modifications each separator may be replaced by separators in parallel, and the separators may be contained in a common housing.
