Patent GB-655011-A (GB)
Title: Lubricating grease
Filed: 1948-10-12
Abstract: A liquid or semi-fluid lubricating composition, which acquires a grease-like consistency on mechanical working, comprises mineral lubricating oil and from 8 to 35 per cent, based on the total composition, of a mixture of alkali metal soaps of one or more fatty acids having 12-22 carbon atoms in the molecule and alkali metal salts of one or more carboxylic acids having 2-4 carbon atoms in the molecule.  The composition may also contain an anti-oxidant such as phenyl alpha- or beta-naphthylamine.  Other ingredients, which may be present, are extreme pressure compounds, oiliness agents, viscosity index improvers, tackiness agents and rust inhibitors.  The carboxylic acids having 2-4 carbon atoms in the molecule may be saturated acids, such as acetic, propionic or butyric acids, or unsaturated acids, such as acrylic, methacrylic or crotonic acids, the unsaturated acids being preferred.  The fatty acids having 12-22 carbon atoms in the molecule are preferably the partially hydrogenated fatty acids, especially those which are quite highly unsaturated.  The saponifying agent used in the preparation of the salts or soaps may be sodium hydroxide, potassium hydroxide or a mixture of the two, although other saponifying agents producing alkali metal soaps or salts may be used at least in part.  The C12-22 acids and the C2-4 acids may be saponified simultaneously after adding them to mineral oil, thereby producing the finished lubricating composition.  Thus, according to one process of preparing the lubricating composition, sodium hydroxide or potassium hydroxide or a mixture of both is added to a mixture of the oil, the C12-22 acids and the C2-4 acids and the product is heated with continual stirring to at least 450 DEG  F., whereupon the fine dispersion thus obtained of soaps and salts in the oil is cooled with stirring to between 200 DEG  and 250 DEG  F. and finally cooled without further working.  In the examples, lubricating compositions are described consisting of (1) mineral lubricating oil, sodium soaps of hydrogenated menhaden oil fatty acids, sodium acrylate and phenyl alpho-naphthylamine, and (2) mineral lubricating oil, sodium and potassium soaps of hydrogenated menhaden oil fatty acids, sodium and potassium acetates and phenyl alpha-naphthylamine.  For comparison purposes, a lubricating composition is described consisting of mineral lubricating oil, sodium soaps of partially hydrogenated menhaden oil fatty acids and phenyl alpha-naphthylamine.

Title: Preparation of vinyl esters of chemically stabilized rosins and polymers thereof
IPC: C08F18/04
Filed: 1950-11-03
Abstract: Vinyl esters of rosin acid which has been hydrogenated, dehydrogenated or disproportionated are prepared by contacting the treated rosin with acetylene in liquid phase under superatmospheric pressure and in the presence of a catalyst which is a carboxylate of zinc, cadmium or mercury.  The ester is separated from the reaction mixture which in addition to unreacted materials may include polymers of acetylene and of the vinyl esters, by distillation.  Carboxylates mentioned are acetate, stearate, benzoate or the salts of hydrogenated or dehydrogenated rosin.  The two latter salts may be formed in situ by dissolving the metal oxide in the appropriate acid. In one example p.-tert-butyl catechol was added to the reaction mixture as a polymerization inhibitor.  The term rosin acid includes wood rosin, gum rosin, acid fractions therefrom and tall oil.  The p products may be polymerized in presence of a peroxide catalyst, by heating or by ultra-violet radiation (if desired with addition of activators such as diacetyl or acetone).  The polymers are soluble in hydrocarbons or chlorinated hydrocarbons.  Peroxide catalysts mentioned are benzoyl and acetyl peroxide; dibenzal diperoxide; cumene hydroperoxide; di-(a .a -dimethyl benzyl) peroxide; di - tert. - butyl peroxide; tert. - butyl perbenzoate is also mentioned. Polymerization may be in bulk, in solution in an inert solvent or in aqueous emulsion.  The polymers may be obtained as amorphous powders by precipitation with ethyl alcohol from the reaction mixture.  They may be cooked with drying oils, e.g. tung oil to yield varnishes and enamels, dissolved in solvents to yield ink vehicles, used as parafin wax modifiers for water-proofing cardboard or combined with natural or synthetic rubbers such as neoprene or G.R-S. to make solvent-type adhesives.

Patent GB-1110702-A (GB)
Title: Method and apparatus for manufacturing oil black
Inventor: RUBLE THEODORE ALLEN
IPC: C09C1/50
Filed: 1965-06-25
Abstract: In the furnace process for the manufacture of carbon black a carbon-black-producing hydrocarbon feedstock is introduced into a turbulent burning mixture of fuel gas and air at one end of an elongated reaction zone to produce a reaction zone effluent of carbon black suspended in by-product combination and dissociation gases from which the carbon black is subsequently removed, and wherein, before said feedstock is so introduced, it is subjected to a vapour stripping operation by passing a gas through the feedstock, said gas and the vapour derived from the feedstock being used as said fuel gas. Oil black feedstock is introduced into the flash tank 10 through conduit 12 after having been preheated to permit easy stripping of volatile material.  The feedstock is introduced to raise the level of liquid in the flash tank to the level of flow 22.  A metered flow of lean combustible gas is then introduced to flask tank 10 through 14 and 16.  The gas may be preheated to from 500 DEG  F. to 2000 DEG  F. Fuel gas from the flash tank 10 then passes through the discharge pipe 26 into a preheat coil 62 of the carbon black reactor 30.  Heavy ends of the raw liquid feedstock from flash 10 is drawn through 32. Atomized vapour strip feedstock is injected from the spray head 72, air is introduced to the annulus 76 so as to provide a concentric flow of air around the spray head 72 and directing the atomized feedstock axially down the centre of the inner metallic reactor tube 50. Air which has been introduced into the annulus between 50 and 44 downstream in the reactor is mixed with the inert fuel gas in the chamber 46.  The mixture is ignited as it flows into the inner reaction tube 50 so as to form an annular sheet of flame and hot combustion products surrounding the atomized axially injected feedstock. Effluent gases take the form of an oil black aerosol. The product is isolated in the usual way.  The vapour stripping medium may be natural gas or synthesis gas.  By-product combustion and dissociation gases may be recycled as the vapour stripping medium.

Patent GB-1026666-A (GB)
Title: Insulated container
IPC: B65D88/12
Filed: 1963-07-10
Abstract: 1,026,666. Tank wagons. UNION TANK CAR CO. July 10, 1963 [Aug. 21, 1962], No. 27301/63. Heading B7L. [Also in Division B5] An insulated container such as a railway tank car is made by positioning inner and outer shells in spaced relation, sealing off portions of the inter-shell space and charging said portions with foamable and hardenable material. As shown, an inner shell 15, which may be relatively flimsy, e.g. of thin stainless steel, glass-lined steel or plastics material, is bound at intervals. with tubular bands 25, e.g. of polythene, held in place by circumferential wire ties. An outer shell 16, of heavy gauge steel, aluminium or other strong material and made in several sections (three, a central and two end sections are shown) is fitted over the inner shell and supports it by internal blocks 32. To apply the insulation the ends 26 of the tubular bands 25 are drawn through apertures 30 in the outer casing (the wire ties being withdrawn), and the bands are then filled with foamable material, or inflated, to seal off the inter-casing space into compartments, the latter being then filled with foamable material through apertures 45 or by using the apertures 20, the foam being allowed to harden. The operations may be carried out in any order provided each space is sealed before filling, but is preferably carried out from one end, the spaces being sealed, and then filled, in succession. The size of the spaces is selected such that the appropriate quantity of foamable material can just be introduced within the pre-foaming time of the material. The inner shell 15 may be rigidified before introducing the foamable material around it by filling with water or other liquid or with air under pressure, or this shell may be made of rubber or other inflatable material, being enclosed in the outer shell in collapsed state and then inflated and so held until after the surrounding foam has set. During the process of the invention the assembly is heated to a temperature, e.g. 120 F., above that likely to be encountered in use, for example by introducing steam into the inner shell where this is unfilled. The completed tank as shown is stated to be structurally strong enough for use as such (mounted on axle trucks) as a railway tank car without the need of an underframe.

Title: Improvements in or relating to breeches for guns
IPC: F41A3/04
Filed: 1946-09-12
Abstract: 616,629. Ordnance. VICKERS-ARMSTRONGS, Ltd., HESELTINE, J. C. W., and BARRETT, R. H. Sept. 12, 1946, Nos. 27452 and 37296. [Class 92 (ii)] The breech mechanism of a gun is carried by a breech ring 1 which is mounted on a barrel ring 2 for eccentric rotation with respect to the barrel 3 for opening and closing the breech, the extent of rotation of the ring being normally limited by the engagement of a pivoted stop catch, Fig. 8, with fixed stops 45, 46, but the arrangement being such that the catch may be moved clear of the stop 46 so that the breech ring may be further rotated and removed from the barrel ring as by unscrewing. The stop catch shown is pivoted at 41 and has two arms 40a, 40b of which arm 40b is urged inwards by a spring 43 to bring a projection 40c on the arm into the path of the two stops. Finger pressure on a part 40d of arm 40a enables the projection to move clear of the stop 46. The breech ring is rotated between its open and closed position by a handle 9 fitted with a spring-controlled pivoted lever for actuating a locking plunger. When the breech ring is rotated from the closed position shown to the open position, a roller 14d, Fig. 2, on a threearmed cocking lever engages with a cam 22 on the barrel ring. This causes the lever to pivot, an arm 14c compressing a main spring 15 and arm 14a retracting the striker assembly 13. Coacting with the striker assembly is a trigger sear 17 which slides in an aperture 25 in the breech ring and which is actuated by a firing plunger 50 in the barrel ring. A safety lever 19 pivoted on a stud 28 can be moved to either of two positions, in one of which its arm locks the cocking lever against rotation for firing. The breech ring also carries a pivoted spring- controlled lever 30 formed with a cam surface such that when the breech ring is moved to the, open position this cam will engage with a roller on an extension arm of the pivoted extractors.
