A unit for converting felled timber into shorter lengths comprises a carrier 2 for a portable chain or band saw mounted upon a support 5 and displaceable about axes arranged substantially at right angles to one another. The carrier consists of two parts 7, 8 which are joined at one side by a hinge 9 and at the other side by a screw 10 and is provided with brackets 34 for supporting the saw. The carrier is mounted for pivotal movement about a horizontal axis on an arm 12 which, in turn, is mounted for pivotal movement about a vertical post 6, the arm being supported by a collar which is adjustable vertically on the arm. A stop 3 limits rotation of the carrier about the arm to 180 degrees. The post 6 is upstanding from the support 5 which comprises a pair of members 16, 17 secured at their intersection, the members forming four legs, three of which have adjustable feet. The support is provided with a stop 19 adjacent a vertically disposed roller 20 against which the timber is urged as it is fed over a horizontal roller 21 inclined to the direction of travel of the timber. The unit also has separate rollers 22 mounted on bases 24 for feeding the timber on to the roller 21, a pivoted lever 18 being provided to lift the timber on to roller 21 if necessary. Each of the rollers has a ramp 25 for rolling the timber on to the rollers. A measuring rack 23 is connectible by links 26 to the support 5 and has a frame which is supported on feet 35 and is provided with a number of rollers 27. The timber is fed between fences 31 on the rack to a position determined by an adjustable stop 28 in the form of a roller 30. In use, the saw is mounted in the carrier and is swung about the arm 12 and the post 6 to an inoperative position while the timber is rolled up the ramps 25 on to the rollers 22 from which it is passed over roller 21, which urges it towards the roller 20 and stop 19 until it abuts the stop 28. The saw is then swung about the post to a position above the timber and then swung about the arm 12 to cut the timber. The saw may be used to cut other material such as boards made of sawdust and chips compounded with resin, synthetic resin material, such as expanded polyurethane or polypropylene, or copper or brass tubing.

Title: Improvements in or relating to processes for the preparation of esters of acrylic and methacrylic acids
Inventor: EDWARDS ERIC DESCAMP
IPC: C07C69/54
Filed: 1955-09-28
Abstract: Monomeric esters of acrylic or methacrylic acid with higher alcohols containing at least 9 carbon atoms are prepared by reacting together the higher alcohol with a methyl or ethyl ester of acrylic or methacrylic acid, which ester may contain an amount of polymerization inhibitor sufficient only to prevent its polymerization at ambient temperature, in the presence of an acidic esterification catalyst containing hexavalent sulphur and a quinone having an oxidation potential of not less than 0.4 volts, the quinone being present in an amount of from 0.03 gms. to 0.20 gms. per gm. mol. of the ester, stripping the reaction mixture free of unchanged methyl or ethyl ester, neutralizing the products, drying if necessary, and then filtering off separated solids.  Specified quinones are p-benzo quinone, p-toluquinone, duroquinone, phenanthrene quinone, dipheno quinone, trichloro quinone, chloranil, o-xylo quinone, 1 : 4-naphtho quinone, quinhydrone and 4 : 7-hydrindene quinone.  Specified acid catalysts are sulphuric acid, alkane-sulphonic acids, benzene sulphonic acid, p-toluene sulphonic acid and sulpho salicylic acid. The reaction is preferably effected by continuously distilling off an azeotrope of liberated methyl or ethyl alcohol and methyl or ethyl ester and passing it into the base of a column containing an upper layer of the starting ester on a lower aqueous layer and withdrawing ester from the upper layer for continuous recycling to the reactor; the aqueous layer preferably contains sodium chloride or other dissolved inorganic salt and a small amount of a polymerization inhibitor, which may be other than a quinone, e.g. toluene.  During the reaction air may be blown through or over the reaction mixture. Examples illustrate the preparation of lauryl and 3 : 5 : 5-trimethyl hexyl methacrylates and the acrylic and methacrylic esters of a mixture of cetyl and stearyl alcohols from methyl or ethyl acrylate or methacrylate which in some instances contains 0.1% hydroquinone. Comparative experiments are described using hydroquinone or anthraquinone. Other higher alcohols specified are straight chain primary alcohols containing more than 18 carbon atoms, cycloaliphatic alcohols and wool wax alcohols.  The acrylates and methacrylates of the higher alcohols may be polymerized.  According to the Provisional Specification, the alcoholysis may be effected with higher alcohols containing at least 4 carbon atoms, such as n-butyl, n-hexyl, n-octyl, 2-ethyl hexyl, n-decyl and myristyl alcohols using an amount of the quinone which is sufficient to prevent polymerization during the alcoholysis but insufficient to necessitate its removal by special treatment.  Specification 686,624 is referred to.

Patent GB-642751-A (GB)
Title: Continuous bleaching of glyceride oils
IPC: C11B3/00
Filed: 1947-10-16
Abstract: The customary continuous process of refining glyceride oils by alkali treatment, centrifuging, washing, drying and bleaching with fuller's earth or other bleaching clay is modified by bleaching the water-washed oil in the undried state and subsequently removing the moisture either from the oil-earth mixture prior to filtering, or from the filtered oil, by vacuum drying.  More effective decolouration is thereby secured.  According to an example, alkali-refined cottonseed oil issuing at about 130 DEG  F. from the foots removing centrifuges is agitated for a short time in a closed chamber with 15 per cent of water and the mixture fed through another centrifuge to remove the aqueous phase containing dissolved soap and other impurities.  The wet oil is then continuously mixed with a slurry of bleaching clay and previously-refined oil, vigorously agitated and heated to 175 DEG  F. The wet oil-earth mixture passes to a flash tank or drying chamber under reduced pressure where the water vapour is drawn off, and finally passes to a rotary or other filter for removal of the bleaching earth.  The heating of the wet oil prior to flash drying may be done before the addition of the bleaching clay, and the filtration of the bleached oil may be done before the flash-drying step.  The process is applicable to all alkali-refined glyceride fats including lard, tallow, palm oil, coconut oil, cottonseed oil, peanut oil, soybean oil, whale oil, herring oil and sardine oil.
