Title: Improvements in slubbing frames, intermediate frames and roving frames and other similar machines used in "preparing" cotton and other fibrous materials
IPC: D01H1/16
Filed: 1923-10-10
Abstract: 231,707. Platt Bros. & Co., Ltd., and Hall, H. P. Oct. 10, 1923. Guards.-In a slubbing, intermediate, or roving frame the spindle or bobbin rails are formed of sections of sheet metal bent or rolled into shape of troughs or channel opening upwards, and attachments or supports for the spindles, &c. and the shafts and gear for driving the spindles are secured to the sections so that these parts are enclosed and guarded. Guards similarly constructed may be applied to spindle &c. rails of ordinary construction, and covers of sheet metal are applied to enclose completely the parts carried by the rail. In one construction sections of metal plate bent into channel shape with front and back walls b, c, Fig. 2, and bottoms d are secured together by angle pieces or metal straps applied inside or outside. The ends are closed by plates or by the box containing the gears or by part of the machine frame so that the whole comprises an oil tight channel. At intervals a channel shaped cross-bar p is riveted in place by flanges q, r. The bars p carry at intervals brackets 27 with arms 32 to support covers made in sections, adapted to fit into rabbets formed on the arms 32. The cover is in three parts, the front and rear parts h<1>, h<3>, at their lower corners being notched to rest in projections 33 on the arms 32 and the centre portion h<2> being rectangular in shape and overlapping or being overlapped by the other portions. In another construction the cross bars 39, Fig. 11, have bolted to them pedestals 43 to carry top covers 44. Front and rear covers 45 are provided with projections 46, 48 to engage the edges of the front and rear walls b, c and the edges of the top cover 44. The longitudinal bar supported by the cross-bar of channel shape may itself be, of channel shape and have bolted to it brackets to support the various parts. In a further construction two longitudinal bars 62, Fig. 15, of channel shape are bolted to the cross-bars 61 and the front and rear walls b, c. The bars 62 carry at intervals arched cross-bars 67 on which are supported the three-part cover plates 691, 693, 692. The sheet metal trough-shaped member may be applied to rails 70, Fig. 8, of ordinary construction so as to enclose all the gearing immediately associated with the driving of the spindles &c. Angle-pieces 72, 73 bolted to the rail carry the shet metal cover or guard 71. Brackets 75 bolted to the upper part of the rail carry the top covers. The top covers may be made of wood. The edges of the various sheet metal parts may be bent to lie in a plane parallel to the plane and the main portion to stiffen them.

Title: Process for the production of boron hydride hydrocarbon compounds
IPC: C07F5/02
Filed: 1959-07-22
Abstract: Boron hydride hydrocarbons of the formula (Rn BH3-n)m wherein R stands for an aliphatic, cycloaliphatic or aromatic hydrocarbon radical, n is 1 or 2 and m is 1 or 2, are produced by reacting a boron trialkyl, boron tricycloalkyl or a boron triaryl with at least one borohydride of an alkali metal or alkaline earth metal and with at least one boron halide or addition product of a boron halide with an aliphatic or cycloaliphatic ether, in an inert atmosphere, for example nitrogen or argon.  Solvents such as tetrahydrofuran and diethylene glycol dimethyl ether may be used or the reaction may be accomplished in the absence of solvents.  It is preferred to use reaction temperatures of 30-60 DEG C. but the reaction may be completed by boiling under reflux.  Suitable boron hydrocarbons are boron trimethyl, triethyl, tripropyl, tricyclohexyl, triphenyl, tritolyl and tri (ethylphenyl).  Instead of the free boron halides, the addition products with ethers such as dimethyl ether, diethyl ether, tetrahydrofuran or diethylene-glycol-dimethyl ether, may be used.

Abstract: 601,486. Testing physical properties of threads, cords, wires, &c. COURTAULDS. Ltd., and BERRY, J. K. Oct. 3, 1945, No. 25670. [Class 106 (ii)] Apparatus for subjecting fibres, threads, cords, wires, &c. to repeated tensile stresses comprises two members 1, 2, rotated in synchronism, which hold the ends of the cords &c. 5 so that the latter are tensioned, the member 2 being inclined relatively to the member 1 so that each cord 5 is stretched and relaxed during each rotation of the members, and means such as a screw micrometer 11 for adjusting the distance between the members 1, 2 during operation of the apparatus whereby any permanent extension of the cords 5 can be taken up and measured. The members 1, 2 are circular plates provided with clamps 3. 4, respectively, to grip the cords. Each clamp 3 comprises a steel wing-nut and a wrought iron bolt, and the circular plate 1 is of aluminium, this arrangement ensuring an increase in clamping pressure with rise of temperature. Each clamp 4 is mounted for self-alignment on ballbearings. The member 1 is mounted on a shaft 6 supported in a pedestal 9 and driven by belt and pulley means housed partly within the pedestal. The micrometer 11 can be operated to slide an inner shaft 10 (not shown) within the shaft 6, the member 1 being secured to the shaft 10 by a pin which passes through a slot in the shaft 6. The member 2 is mounted on and rotated by a shaft 17 linked by a universal joint to the driving shaft 6. The shaft 17 is carried by a bearing in a pedestal 19 journalled in a step bearing in the base-plate 22. The. pedestal 19 can be swung to incline the member 2 by means of a weight 23 acting on an arm 26 secured to the bearing shaft of the pedestal, this shaft also having secured thereto a pointer 27 co-operating with a scale 28. The clamps 3, 4 may be replaced by knurled'screws with curved washers, and the members 1, 2 may be covered with a material which becomes tacky at high temperatures, whereby the cords 5 are firmly gripped. The apparatus may be enclosed in a casing provided with electric heaters, and thermostatic control of the heaters enable tests at predetermined temperatures to be conducted. The apparatus can be used for testing textile cords for use in motor vehicle tyres.

Title: Epoxidation process
IPC: C07D301/16
Filed: 1966-06-09
Abstract: Unsaturated compounds containing an epoxidizable ethylenic group are epoxidized using a two-phase liquid system comprising an aqueous phase containing an aliphatic peracid generated in situ from an aliphatic acid and hydrogen peroxide in the presence of an acidic catalyst and an immiscible organic phase containing the unsaturated compound in an inert water-immiscible solvent, in which a single discrete fresh or continuously renewed interface is maintained between the aqueous and organic phases during the epoxidation.  The fresh or renewed interface may be obtained, for example, by mild agitation or by rocking the reactor.  The peracid is preferably obtained by reacting hydrogen peroxide with a C1-C6 aliphatic carboxylic acid in the presence of a strong acid catalyst, e.g. sulphuric acid.  In the examples: (a) 1-tetradecene; (b) a C11-C15 1-olefin fraction; (c) a C18-C20 1-olefin fraction; (d) a C15-C18 1-olefin fraction; and (e) 1-hexadecene are epoxidized.
