Filed: 1959-04-29
Abstract: An ethylene polymerization catalyst comprises an organo-aluminium compound AlR3(R=alkyl, e.g. Et, Pr or i-Bu) and a vanadyl salt of a carboxylic acid, in the preferred molar ratio of 1-10 : 1, particularly 3 : 1.  The vanadyl group is attached to two carboxyl groups which may be derived from two molecules of (the same or different) mono- or di-carboxylic acid, or from a single molecule of dicarboxylic acid; the preferred types of such acids are alkyl or alkenyl monocarboxylic acids having at least 2 C atoms, alkylene dicarboxylic acids with at least 1 C atom separating the carboxyl groups, and phenyl mono- and phenylene di-carboxylic acids. Specified vanadyl salts are the acetate, propionate, 2-ethylhexanoate, 2-ethylbutyrate, adipate, benzoate and maleate. The acetate is prepared from V2O5 with acetic acid and anhydride, while the other vanadyl salts are prepared from the acetate and the appropriate carboxylic acid; experimental details are given of the preparation of vanadyl acetate, adipate and benzoate.  The catalyst composition is used as a dispersion or solution in an inert hydrocarbon liquid such as heptane, octane, benzene or toluene.ALSO:Vanadyl salts of carboxylic acids, wherein the vanadyl group is attached to two carboxyl groups which may be derived from two molecules or one or two mono- or dicarboxylic acids or from a single molecule of dicarboxylic acid, are prepared by reacting V2O5 with acetic acid and acetic anhyddride yielding vanadyl acetate which may be reacted with an appropriate carboxylic acid or acids to obtain a different desired vanadyl carboxylate.  Propionic, 2-ethyl hexanoic, 2-ethyl butyric, adipic, benzoic and maleic acids are mentioned.

Title: A self-adjusting mechanism for hydraulic wheel brakes
IPC: F16D65/54
Filed: 1944-07-31
Abstract: 576,814. Linkwork. TAYLOR, A. G. July 31, 1944, No. 14609. [Class 80 (iii)] Also in Group XXXIV] In a self-adjusting mechanism for taking up wear in a hydraulically operated brake, each piston moves axially with respect to an internal rigid member which is not affected by the fluid pressure, and an element within the piston having a degree of free movement relative thereto is adapted to engage successive abutments on the rigid member as wear occurs, to limit the degree of retractive movement of the piston. In the form illustrated, a rod 15 having teeth 16 at each end is disposed coaxially with respect to the pistons 11, the latter of which are each formed with a compartment housing a split ring 18. The axial length of the compartment is such as to permit of a limited free movement of the split ring. As wear takes place, the split rings engage with the successive abutments 16, the extent of movement of the rings being limited by flanges 17 at the ends of the rod. In a modification, Fig. 2, not shown, axial movement of the rod 15 is prevented by a stop member in the cylinder casing located between flanges on a central collar of the rod. In a further modification the split rings are replaced by U-shaped springs, the parallel limbs of which'engage the abutments on the axial rod.

Abstract: 1,157,784. Heat shrinkable plastics tubing. DOW CORNING CORP. 28 March, 1968 [18 April, 1967], No. 14872/68. Heading B5A. Apparatus for expanding polymeric tubing comprises a mould pipe 21 of internal diameter equal to the desired external diameter of the pipe, a supply of tubing 13 of length greater than that of the mould pipe, a gas-tight chamber 11 confining the supply of tubing, means 19 for clamping the tubing at the outlet from the mould pipe 21, a gland at the outlet of the gas-tight chamber for radially confining the tubing, means 27 for supplying gas under pressure to the inside of the tubing and means 16 for supplying gas to the gas-tight chamber 11 to prevent excessive expansion of the tubing in the gas-tight container. The tubing 13 is either wound on a reel 12 or coiled inside the gas-tight chamber 11. It emerges through a gland, against which it is sealed by the greater pressure inside tube 13 than outside, and passes through tube 17 into the mould pipe 21. In operation the tubing is clamped at the outlet end 19 of the mould pipe and the tubing is filled with gas from a high pressure source 14. Valve 16 is adjusted so that the pressure difference across the tube in chamber 11 is at least 0À7 Kg/Km<SP>2</SP> but is not high enough to distort the tube. Steam is then passed around the mould pipe 21 and the contained tubing expands under the internal air pressure to fill the mould pipe. The tubing is then cooled by a flowing cold water through the mould pipe and becomes rigid in the expanded position. The gas supply from 14 is then cut off, the clamp opened, the tubing wound on to reel 24 by one length of the mould pipe and the process repeated. The tubing formed is heat shrinkable. The process cycle may be controlled automatically.

Title: Improvements in mechanism for inserting and removing plug doors of horizontal coking chambers or coke ovens
IPC: C10B25/14
Filed: 1920-06-01
Abstract: 159,788. Wilputte, L. June 1, 1920. Operating and controlling doors electrically, and by toothed gear, screw-and-nut, and lever mechanism.-An apparatus for handling the door O of a horizontal coke oven comprises a lever E pivoted on an axis B<1> parallel and adjacent to the lower edge of the door and adapted to engage the upper end of the door at O<2> and the lower end at M. Thus, on retraction of the lever E the lower edge of the door is lifted and its upper edge pulled forward, so freeing the door from the retort mouth, after which the whole device is withdrawn to carry the door to the rear. The apparatus is mounted on the usual pushermachine carriage R on a horizontally movable rack-operated bar A and the lever E is connected to this bar through the intermediary of a cushion connection comprising a member B hung on the bar A by swing links C, CA and pressed toward the door by a spring D. After the bar A is moved into the approximately correct position, the lever E is actuated, by means of the motor F<4>, gearing F<2>, and connecting rod E<1>, to position the hook G under the hook plate O<2>, after which engagement is effected by means of screw gearing I attached to the rear end of the lever G. The lever G also actuates the locking bar O<4> by means of a connecting lever L<1>, so that, when the lever G is engaged with the plate O<2>, the bar O<1> is raised from the usual slots Q<3> on the door frame leaving the door free to be removed in the manner described above. A buffer M on the lower end of the lever E prevents the door from swinging. In a modification, Fig. 9, more especially suitable for the " coke " side, the lever EA is carried by a double link AA suspended from the coke guide carriage at a point A<20> well above the door, and the necessary relative movements of the lever EA and link AA are obtained by a pair of specially situated and proportioned cranks F<12> and F<10> on a rocking shaft FA. A cushion device consists of a coiled spring Z forming a driving connection between the crankshaft FA and the arc F<14>.
