Title: Mineral oil compositions
Inventor: AGIUS PETER JOSEPH VERMONT JAM
IPC: C08F22/04
Filed: 1956-07-27
Abstract: Lubricating and fuel oil compositions comprise a mineral oil and an oil-soluble copolymer derived from 1 to 10 parts (by weight) of maleic anhydride, 10 to 30 parts of an ester of a vinyl alcohol and a C2-12 monocarboxylic acid, and 50 to 90 parts by weight of an ester of fumaric or maleic acid and a C8-18 alcohol. The C8-18 alcohol is preferably a natural alcohol, e.g. palm kernel alcohol or lauryl alcohol.  The compositions may be oil concentrates of the polymers, which when present as about 5 per cent wt. of the final oil impart good pour point, viscosity index and detergency characteristics to the oil.  Optional additives mentioned are oil-soluble sulphonates, metal salts of alkyl phenol sulphides and E.P., anti-wear and anti-oxidant additives. Examples comprise a mineral oil having viscosities of 180 cs./100 DEG  F. and 12 cs./210 DEG  F. (V.I. = 104) and copolymers prepared from the following ingredients at 60 DEG C. under reflux for 24 hours using 2 per cent benzoyl peroxide as catalyst: (i) 75 parts (weight) lauryl fumarate, 19 parts vinyl acetate, 4 parts maleic anhydride, and 2 parts lauryl alcohol; and (ii) 79, 16, 3 and 2 parts respectively of the same monomers.  The Provisional Specification refers to the similar use of copolymers of maleic anhydride with one or more copolymerizable organic compounds. Examples of such compounds are vinyl esters of C3-20 acids e.g. of tiglic, acrylic, methacrylic, oleic or lauric acids; unsaturated hydrocarbons e.g. simple C3-10 mono olefines, polymerized olefines e.g. ethylene or alkylated styrene, and diolefines e.g. isoprene, ethers and acrylonitrile.  The use of the copolymers in animal or vegetable oils or synthetic lubricating oils such as complex esters and diesters is also mentioned.ALSO:Lubricating and fuel oil compositions comprise a mineral oil and an oil-soluble copolymer derived from 1 to 10 parts (by weight) of maleic anhydride; 10 to 30 parts of an ester of a vinyl alcohol and a C2-12 monocarboxylic acid; and 50 to 90 parts by weight of an ester of fumaric or maleic acid and a C8-18 alcohol.

Title: Improvements in turnstile antenna
IPC: H01Q21/26
Filed: 1944-11-23
Abstract: 583,731. Aerials; impedance networks. FARNSWORTH TELEVISION & RADIO CORPORATION.' Nov. 23, 1944, No. 23381. Convention date, Feb. 14. [Classes 40 (iii) and 40 (v)] A turnstile antenna, consisting of four equal length radiator elements located in the same plane at 90 degrees spacing, has a pair of quarter - wavelength transmission lines connected respectively between separate pairs of adjacent elements and means for matching each radiator element impedance to the characteristic impedance of the transmission lines, two opposite radiator elements being coupled in phase opposition to the conductor associated with the radio apparatus. In Fig. 1, the 4 radiators N, E, S, W, each a quarter-wavelength long, have quarter-wavelength transmission lines 15 and 16 connected between the inner ends of N and W, S and E. Condensers 11, 12, 13, 14, one side of each of which are grounded, are used to tune their respective radiators to resonance and adjustment of the effective length of the radiators, with corresponding adjustment of the condensers to maintain resonance, is then made to match the impedance to the radiators to that of the attached transmission lines. The outer sheaths of the transmission lines are earthed as shown. A full wavelength line AB, Fig. 2, is connected to the points A and B, Fig. 1, and a feed connection C attached to it at D such that AD is a quarterwavelength and BD three-quarters of a wavelength, whereby the radiators are excited in phase quadrature. It is stated that providing the radiators are all equally long, the length may be any desired value and in some cases inductive elements may then be required instead of condensers for tuning. An alternative form of phasing and feeding system utilising a balanced network of 2 condensers in series with an inductor may be used, Fig. 3 (not shown).

Title: Process of reacting carbohydrates and polyhydric alcohols derived therefrom with various reagents
IPC: C07H13/06
Filed: 1956-08-07
Abstract: At least one hydroxy group of a carbohydrate or polyhydric alcohol derived therefrom is reacted with a reagent reactive with said hydroxy group in an inert solvent selected from 2-pyrrolidone and N-methyl-2-pyrrolidone (for numerous specified reagents see Group IV (b)).  In examples: (2) octastearyl sucrose is used together with dioctyl phthalate to plasticise polyvinyl chloride; (5) sucrose is reacted with maleic anhydride in N-methyl-2-pyrrolidone to give a high molecular weight compound of probable formula <FORM:0806935/IV (a)/1> which may be further reacted through the double bond with polymerizable vinyl compounds such as styrene; (8) sucrose is reacted with 1,4-dichloro-2-butyne in 2-pyrrolidone to give a product of general formula <FORM:0806935/IV (a)/2> which may be further reacted with polyamines through the unsaturated bond; (14) inulin is reacted with maleic anhydride in N-methyl-2-pyrolidone to give a high molecular weight compound of probable formula <FORM:0806935/IV (a)/3>ALSO:At least one hydroxy group of a carbohydrate or polyhydric alcohol derived therefrom is reacted with a reagent reactive with said hydroxy group in an inert solvent selected from 2-pyrrolidone and N-methyl-2-pyrrolidone.  The method may be used for esterifying the hydroxy compound with organic or inorganic acids (many specified), acid anhydrides or acid halides or by alcoholysis; nitrous anhydride gives nitrous esters; phosphorus oxychloride gives phosphates; zinc chloramine gives amines.  The action of phosphorus tri- or penta-halides gives halo-derivatives from which may be obtained: nitriles by reaction with KCN; thio alcohols by reaction with KSH; phosphates by reaction with silver phosphate and amines by reaction with ammonia.  Reaction with an alkali metal such as Na, K or Li gives carbohydralates or alcoholates which may be recovered by evaporation or precipitation with dioxan; these metal derivatives may be reacted with halides, including those prepared by the process of the invention, to give ethers.  Numerous mono-, di-, tri- and poly-saccharides and carbohydrate alcohols are mentioned as suitable. In examples: (1) and (10) sodium sucrosate and sodium glucosate respectively are prepared by reacting the sugar with sodium metal dissolved in N-methyl-2-pyrrolidone; (2) and (6) octastearyl sucrose, (3) tetrastearyl sucrose, (11) octastearyl rhamnose, and (12) tetrastearyl threose are prepared by the action of stearyl chloride on the sugar in solution in one or other pyrrolidone; (4) sucrose and (13) raffinose are reacted with acetic anhydride in N-methyl-2-pyrrolidone to give, probably, sucrose and raffinose tetra-acetates; (7) a partially chlorinated sucrose is prepared by the action of sulphuryl chloride on sucrose in N-methyl-2-pyrrolidone; (9) alcoholysis is effected between sucrose and cottonseed oil in the presence of sodium methylate in N-methyl-2-pyrrolidone.

Title: A method of and an apparatus for removing condensable vapour from a container
IPC: F28B1/00
Filed: 1959-07-17
Abstract: A container 1, in which moist articles are <PICT:0923072/III/1> to be dried, is connected via rotary pump 6 and by-pass 7 to a condenser-assembly 11, comprising two coils 12 and 13, which is joined by pipe 19 to pump 22.  Coil 12 is cooled by passing cold water through it.  Coil 13 is maintained at low temperature by refrigerating machine 18.  When the perforated holder 2 in container 1 has been charged with the articles to be dried, pump 22 is started-up, and valve 8 in by-pass 7 is the open-position. The water-vapour, evolved from the moist articles, passes through by-pass 7 and is condensed on coil 12 until the vapour pressure has decreased to the vapour-pressure of water at the temperature of coil 12.  But when coil 12 ceases to be effective, coil 13 is brought into operation.  Finally, when coil 13 ceases to effect condensation, valve 8 is closed and pump 6 is operated so as to increase the pressure of the water-vapour flowing to the condenser-assembly.  The entry and exit temperatures of the cooling water flowing through coil 12 may be continuously determined by contact thermometers and, with the aid of a relay, the refrigerating machine may be started up as soon as the temperature-difference drops below a given value.
