Abstract: 1,125,502. Skinning pigs. S. C. JOWETT. 30 June, 1967 [6 April, 1966], No. 15310/66. Heading A2U. In skinning the carcass of a pig, it is scalded and scraped, to remove surplus hair and bristles, at least one incision is made in the skin to allow a selected area of skin to be removed, an end or edge of said area is cut free from underlying fat, means are attached to the freed portion of skin, and a pulling force is applied, e.g. to said means, to peel the selected area of skin from the carcass. The carcass 1, Figs. 2 and 3, is hung head-downwards, by its hind legs 2, from a rail 3, and the head 9 is preferably anchored to the ground, or a floor, by a hook 10. After being stuck and bled, the carcass is scalded and scraped, an incision 4 is made around a selected area 5 of skin, and an edge of the lowest, V-shaped part 6 of the area 5 is cut free from underlying fat, and gripped, as by tongs or grips 7, and pulled, as by a rope or chain 8, to peel the area of skin 5 from the carcass. The cuts 4a forming the side edges of the part 6 may be at an angle of 45 degrees to each other. Preferably the carcass is skinned immediately after being scalded and scraped, i.e. when the temperature of the carcass is between 132 and 142‹F. Skinning may be effected before the carcass is eviscerated. Alternatively, the carcass is suspended head-upwards.

Abstract: 1,243,319. Oxirane compounds. SHELL ININTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 1 April, 1970 [2 April, 1969], No. 15372/70. Heading C2C. Olefinic compounds are reacted with organic hydroperoxides to give oxirane compounds, the reaction being carried out in the presence of a catalyst composition consisting of silica or an inorganic silicate having a surface of silanol groups which is insoluble in the reaction mixture. The olefinic compounds may be hydrocarbons or may be substituted, for instance, by halogen atoms or hydroxyl groups, e.g. ethvlene, propylene, isobutylene, hexene-3, octene-1, decene-1, butadiene, allyl alcohol, crotyl alcohol and allyl chloride. A solvent for the reactants, e.g. benzene, toluene, chlorobenzene, bromobenzene, o-dichlorobenzene, octane, decane or dodecane may be present. The hydroperoxide is converted during the oxidation of the olefinic compound to the corresponding alcohol. In the examples (a) 1-octene is treated with t-butyl hydroperoxide to give 1-octene oxide; (b) cyclohexene is treated with t-butyl hydroperoxide to give cyclohexene oxide; and (c) 4- cyanocyclo hexene is treated with t-butyl hydroperoxide to give 4-cyano cyclohexene oxide.

Abstract: 1335152 Treating exhaust gases O SHUFFMAN 5 April 1972 [5 April 1971] 15637/72 Heading F1B [Also in Divisions B1 and F4] Method of removing pollutants from waste combustion gases which comprises directing the combustion gases into direct contact with an ice surface supported by a heat exchanger subsurface which is maintained at a low temperature to cause moisture in the gases to condense and freeze on to the subsurface, the moisture contained in the gases to thereby form and maintain the ice surface, on which particulate pollutants are deposited and gaseous pollutants taken up, concomitant with the sloughing off from the ice surface of an aqueous sludge containing pollutants scavenged from the gases, the sludge being moved to a collecting zone and the residual gas being directed out of the zone. Fig. 1 shows the compressor 10, condenser 11, receiver 12, expansion valve 13 and evaporator 14 of a conventional refrigerating system which may be the air conditioning unit of a vehicle. Refrigerant from the receiver 12 can also be directed by line 16 to expansion valve 17 and hence to an evaporator coil 19 in an ice contact chamber 20. From the coil the refrigerant returns through a valve 22 to the compressor suction line. The ice contact chamber, Fig. 2, consists of a coiled tube 18 in a housing 20 which contains upper baffles 30 and lower baffles 31, the latter having openings in their lower edges defining a channel along which the sludge is moved by the exhaust gases into a collection chamber 26. The sludge accumulates in the bottom of the chamber and the residual gases pass upwards through a screen 39 and leave by an exit 40. The upper part of the chamber is cooled by a tube 25 through which refrigerant circulates. Sludge can be removed through a drain 38. Water which separates from the sludge is returned by a pump 49 to the exhaust line 28 of the engine and enters it at a point upstream of the normal muffler. Excess water is directed to a drain 53 via a valve 52. To bring the apparatus into operation quickly when the engine is started a tank of liquefied gas 8, Fig. 11 (not shown) may be provided and connected to the inlet of the coil in the ice contact chamber through a valve which is opened when the starter motor is operated or the ignition is switched on. The gas expands through the coil in the ice contact chamber and quickly cools it.

Patent GB-888644-A (GB)
Title: Improvements in the production of cyclohexanol
Inventor: POEHLER GUENTER
Filed: 1960-01-26
Abstract: Cyclohexanol, together with mono- and dicyclohexylamine, is produced by mixing hydrogen (or a mixture of hydrogen and water-vapour) at at pressure above 60 atmospheres and preheated to 150 DEG C. to 300 DEG C., with a preheated liquid mixture of nitrobenzene and water, in such proportions that a mixing-temperature of 160 DEG C. to 250 DEG C. is established and the weight-ratio of nitrobenzene to water added in the liquidphase lies between 1 : 1 and 1 : 3, and then passing the mixture over a hydrogenationcatalyst at a hydrogen partial pressure of at least 30 atmospheres, the temperature in the catalyst-zone not being allowed to exceed 300 DEG C.  In order to obtain a product which contains mainly cyclohexanol, a large amount of water (within the specified limits) and a hydrogenwater mixture preheated to 250 DEG C. to 300 DEG C. are employed.  When a small amount of water is used, and the hydrogen is not preheated to such a high temperature, the product contains large proportions of mono- and dicyclohexylamine, besides cyclohexanol.  Suitable catalysts are the metals or compounds of the iron or platinum group, and the oxides or sulphides of the metals of the 5th and 6th groups of the Periodic System, possibly with copper and/or manganese compounds.  In an example, a 1 : 2 mixture of nitrobenzene and water, preheated to 180 DEG C. under a pressure of 200 atmospheres, and a stream of hydrogen, heated up to 250 DEG C. under pressure of 200 atmospheres, are introduced into the top of a vertical tube which contains annular filler bodies of iron in the upper section while the lower section contains granular catalyst comprising metallic nickel and metallic copper supported on silica.  The mixing-temperature is 190 DEG C.; and the temperature in the reaction chamber is 275 DEG C.  The gas speed is 0.35 metre per second with reference to the empty tube.  The effluent vapours are condensed.  The product consists of cyclohexanol (7.1%), monocyclohexylamine (19.2%) and dicyclohexylamine (9.7%).

Title: Oil soluble ester polymers and copolymers
IPC: C10M151/02
Filed: 1959-05-07
Abstract: The Specification comprises polymers or copolymers of an amino ester of the general formula where R1, R2, R3, R4 and R5 are hydrogen or alkyl groups, and at least one of R4 and R5 is an alkyl group.  The amino ester may be copolymerized with unsaturated esters, such as <FORM:0854658/IV(a)/1> mono-, or diesters of unsaturated dicarboxylic acids, e.g. a mixture of maleic and fumraic acids, esters of unsaturated fatty acids, esters of unsaturated alcohols such as vinyl acetate, which esters may contain alkoxy groups, styrene, acrylonitrile, or maleic anhydride.  The polymerization step may be effected by heat or increased pressure, without or with a catalyst such as azodiisobutyronitrile and in a solvent such as benzene, chloroform, carbon tetrachloride, paraffin or naphthenic oil.  A specified amino ester is dioctyl amino - maleate and this was preferably copolymerized at 75 DEG C. for 5 hours in the presence of benzoyl peroxide with the fumarate of natural C8 alcohols, the fumarate of natural C16 alcohols, and vinyl acetate. The products may be used as additives for lubricating oils, for stabilizing fuel oils, for flotation agents, dispersants for insecticides, additives for natural and synthetic rubber and dispersion agents for asphalt and linoleum.ALSO:Dioctyl amino-maleate which may be polymerised or copolymerised (see Group IV(a)) may be prepared by chlorinating maleic anhydride at 140 DEG C. in the presence of a catalyst, the substance thus obtained then hydrolysed and esterified at 120 DEG C. by a C8 aliphatic alcohol to produce a hydroxy-ester which may then be reacted with ammonia at 40 DEG C. and dehydrated at 120 DEG C. to obtain the amino ester: <FORM:0854658/IV(b)/1>ALSO:Polymers or copolymers of an amino ester of the general formula: <FORM:0854658/III/1> where R1, R2, R3, R4 and R5 are hydrogen or alkyl groups, and at least one of R4 and R5 is an alkyl group (see Group IV(a)) may be used as additives for mineral or synthetic lubricating oils or as additives for fuel oils.  Lubricating oil compositions containing the additives have improved detergency and antioxidant properties, higher viscosity index and lower pour point, while fuel oils are stabilized by the additives.  The amino esters may be copolymerized with one or more polymerizable organic compounds, such as unsaturated esters (e.g. vinyl acetate, mono- or di-esters of maleic or fumaric acid or esters of unsaturated fatty acids; these esters may carry substituents such as alkoxy groups), unsaturated hydrocarbons (e.g. styrene), unsaturated nitriles (e.g. acrylonitrile) and unsaturated dicarboxylic acid anhydrides (e.g. maleic anhydride).  Sulphurcontaining alkyl phenol salts of metals such as barium octyl phenol sulphide may also be added to the lubricating compositions.  In an example, a copolymer of fumarate of natural C8 alcohols, a fumarate of natural C16 alcohols, dioctyl amino-maleate and vinyl acetate was added to a paraffinic mineral oil, with or without P2S5-treated octyl phenol neutralized with baryta.
