Title: Balanced phase modulator
IPC: H03C5/00
Filed: 1961-03-22
Abstract: 910,638. Phase and frequency modulation. HUGHES AIRCRAFT CO. March 22, 1961 [April 18, 1960], No. 10520/61. Class 40 (5). A phase-modulated wave of relatively large phase swing is produced by vectorially combining a carrier with a smaller amplitude signal carrier of different but adjacent frequency, e.g. a single sideband wave, so that the carrier is of opposite phase in each case but the signal bearing carriers are in phase, then taking as output the sum of unequal portions of the vector combinations. As shown, S.S.B. waves and carrier of greater amplitude are vectorially combined in tertiary transformers 12, 13 respectively, then amplified by transistors, limited between fixed amplitudes by diodes 33-37 and applied to a potentiometer 40 with off-centre tapping 41 producing an output of added unequal portions of the limited vector resultants. An R-C output network may convert the output to frequency modulation.

Title: Improvements relating to chill stability and foam adherence of beer
IPC: C12H1/14
Filed: 1965-03-12
Abstract: The chill stability and foam adherence properties of beer which is preserved against microbial growth with a heptyl para-hydroxybenzoate or an alkali (e.g. sodium) or alkaline earth metal salt thereof, is improved by adding to and intimately admixing with the beer (1) propylene glycol alginate and (2) a cobalt salt or a composition, designated FS-26W, composed approximately of 70% zinc sulphate heptahydrate, 2.5% calcium di-sodium ethylenediamine tetra-acetic acid, 2.5% glycine and 25% gum arabic (powder); this composition FS-26W may be varied slightly without materially altering its properties.  The cobalt salt, which should furnish cobaltous ions in solution, is exemplified by cobaltous chloride, cobaltous nitrate, cobaltous citrate, cobaltous sulphate and cobaltous acetate.  It is preferred to add the addition (1) and (2) from a single stock solution directly into the beer stream following the final filtration, and to add the preservative benzoate as a solution in ethanol to the beer stream following the final filtration. Alternatively, all three additions may be made simultaneously from a combined stock solution.  The following ranges of proportions for the additives are disclosed, expressed in parts by weight per million parts by volume of the treated beer: 5-20 parts of the benzoate, 20-500 parts of the alginate and 0.1 - 10 parts of the cobalt salt or 40-120 parts of the composition FS-26W.  Lager beer treated according to the procedure of the various Examples contained 12 p.p.m. of benzoate, 20 or 40 p.p.m. of the alginate, and either 0.5 or 1.2 p.p.m. of cobalt or 60 or 120 p.p.m. of composition FS-26W.

Patent GB-1030792-A (GB)
Title: Improvements in or relating to tocopherols and sterols
IPC: C07D311/70
Filed: 1963-03-19
Abstract: In a process for separating tocopherols and sterols from a mixture also containing higher fatty acids, sterol esters and glycerides (e.g. deodorizer sludge), (1) the mixture is extracted with a polar liquid solvent and a non-polar liquid solvent in a volumetric ratio such that there is obtained a first polar liquid solution rich in higher fatty acids but poor in tocopherols, sterols, sterol esters and glycerides, and a first non-polar liquid solution immiscible with the first polar liquid solution and poor in higher fatty acids but rich in tocopherols, sterols, sterol esters and glycerides, and (2) the components of the first non-polar liquid solution are extracted with a polar liquid solvent and a non-polar liquid solvent in a volumetric ratio such that there is obtained a second polar liquid solution rich in tocopherols and sterols but poor in sterol esters and glycerides, and a second non-polar liquid solution immiscible with the second polar liquid solution and poor in tocopherols and sterols but rich in sterol esters and glycerides.  The initial material may be reacted with an alkali metal hydroxide to convert the higher fatty acids to their salts.  The second polar liquid solution may be concentrated and cooled to crystallize out the sterols.  In an example, the polar solvent in both steps is 96% by volume of methanol and 4% by volume of water, and the non-polar solvent in both steps is hexane. Other polar solvents mentioned are acetone, acetonitrile dimethylformamide, furfural and dimethylsulphoxide, and other non-polar solvents mentioned are benzene and carbon disulphide.

Abstract: 1448531 Pneumatic tyre manufacture GOODYEAR TIRE & RUBBER CO 11 March 1974 [6 April 1973] 10765/74 Heading B7C [Also in Divisions B4-B5] A pneumatic tyre is manufactured by placing a carcass ply, bead cores, a breaker ply and other components on a cylindrical drum, the bead cores being spaced by a distance such that, on shaping the tyre blank to the toroidal form in a mould, the cords of the carcass ply which lie at an angle of 75-90 degrees to the mid-circumferential plane, will be tensioned so as to resist axial compression of that ply beneath the breaker ply; the carcass ply at least in the shoulder regions being partially cured by electron radiation of between 1 and 5 megarads prior to application to the drum. The illustrated tyre includes two polyester cord, carcass plies 16, 18 and two folded, rayon cord breaker plies 20, 22, and the carcass plies are subjected to radiation over a distance W corresponding to the distance W<SP>1</SP> in the completed tyre. Radiation of each carcass ply from the side which in the completed tyre will be radially inwardly results in a maximum dose within the elastomer and little or no curing of the other side. Only one of the carcass plies may be subjected to electron radiation, or the plies may each be radiated from the side which will be radially outwardly in the finished tyre or from both sides.

Title: Improvements relating to the production of organic fertilisers
IPC: C05F9/04
Filed: 1937-04-19
Abstract: Dehydrated humus fertilizers containing in soluble form one or more plant nutrients such as nitrogen, phosphoric acid and/or potash are obtained by adding to an organic base material, such as town or house refuse, a predetermined quantity of one or more inorganic materials capable of providing the required percentage of the one or more plant nutrients and fermenting the mixture within a closed chamber by the action of introduced aerobic thermophile bacteria, until the mass has become dehydrated and sufficiently converted to produce a humus fertilizer containing in close combination the desired excess of the one or more plant nutrients in soluble form, artificial aeration of the mass being carried out during the fermentation and undue acidity being prevented by the addition of inorganic alkaline material.  If desired, a preliminary fermentation by means of anaerobic bacteria may also be employed.  Suitable inorganic materials are nitro-chalk, nitro-lime, sodium nitrate, sulphate of ammonia, superphosphates, basic slag, kainit, potash, &c.  If the inorganic materials are soluble they may be dissolved in a bacteria infested liquid, such liquid being sprayed upon the organic base material, or the dry inorganic materials may be mixed with the organic base material.
