Title: Polymerisation Catalyst for Manufacture of Linear Homopolymers of Butadiene with a High Cis-1,4 Units Content.
Inventor: DAWANS FRANCOIS
IPC: C08F136/06
Filed: 1968-04-10
Abstract: 1,178,366. Polymerization catalyst for butadiene. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 10 April, 1968 [13 April, 1967; 15 Sept., 1967], No. 17326/68. Heading C3P. A polymerization catalyst for butadiene is made by reacting dodeca-2,6,10-triene-1,12-diyl nickel with trifluoroacetic acid and molecular oxygen in a proportion of less than 2 grammolecules per gram-atom of nickel and thereafter removing unreacted trifluoroacetic acid. The reaction with oxygen may take place prior to or simultaneously with, the reaction with trifluoroacetic acid. In a modification the nickel compound may be prepared in situ, i.e. by reacting a zerovalent nickel compound with butadiene in the proportion of 3 to 20 moles of butadiene per mole of nickel compound. The nickel compound may be bis-allyl Ni, bis-cyclooctadiene Ni, cyclododecatriene (1,5,9) Ni, or cyclooctatetraene Ni. The polymerization of butadiene may be carried out in bulk or in a liquid hydrocarbon, and the resulting homopolymer has a very high cis-1,4 configuration.

Abstract: 665,508. Motor vehicles. DOT CYCLE & MOTOR MANUFACTURING CO., Ltd., and WADE, B. S. Oct. 2, 1950 [July 2, 1949], No. 17532/49. Class 79(iii) In a motor vehicle having a steerable front wheel driven by a power unit which swivels therewith, the exhaust system comprises a first part which swivels with the first wheel and which is pivotally connected on the steering axis with a second part carried by the trailing part of the vehicle and terminating at the rear thereof. As shown, the power unit is mounted between a pair of vertical sheet metal members 20 which are secured'to the. steering column and turn therewith. Exhaust passes through the silencer 40 and through pipe 41 into a hollow cross member 28, Fig. 3, fixed to the bottom of the steering column 19, and through port 42 into the interior of the steering column. The latter is journalled by roller bearings 18 in the steering head 17 which is fixed to the front end of the tubular backbone 6. The steering column 19 has one or more holes 44 through which the exhaust passes into the space between column 19 and steering head 17 and thence into the backbone tube 6 and out at the rear. The bearings 18 are protected from the exhaust by packing 45, e.g. of graphited asbestos or steam packing. The tubular backbone may be replaced by a tubular U- shaped frame, the exhaust passing through both limbs thereof, or a pressed steel frame with appropriate cavities for the exhaust. A frameless vehicle would be provided with separate exhaust pipes. The arrangement may also be applied to a four-wheeled vehicle in which each of the front wheels has its own power unit which swivels with the wheel, the exhaust gases being taken through a hollow steering pin.

Abstract: 477,341. Discharge apparatus. PINTSCH AKT.-GES., J. June 25, 1936, No. 17673. Convention date, June 28, 1935. [Class 39 (i)] In an ultra-high-frequency valve of the kind comprising a chamber resonator closed on nearly all sides, the resonator is tunable. In one form the resonator is formed by the envelope 1 and by the conductor 2 connected to the grid 7. The resonator capacity is varied by movement of a plate 16, operated by a screw 17 and mounted on a flexible wallportion 19. In a modification, the outer wall is in two parts joined about the middle by a flexible portion and the internal conductor is in two parts, preferably such that one of them, the aerial 5, slides in a recess in the other. One part of the outer casing has a ring screwed on it and this ring bears against a shoulder on the other part, permitting micrometric adjustment. In a split anode magnetron the outer wall may be flexibly connected to the inner conductor, and a ring screwed on it may bear against the aerial counterpoise 6. For fine adjustment, the two parts of the outer wall may carry threads of slightly different pitch ; a cylinder engaging both threads then causes slight displacements on rotation.

Class 51(i) In a hopper bottom pulverized fuel fired furnace adapted to operate with evacuation of slag in molten form, a cyclone furnace is arranged to discharge gases through an opening at the bottom of the hopper bottom and through the hopper bottom into the pulverized fuel fired furnace. In the furnace shown, Fig. 1, the tube lined combustion chamber 1 arranged for corner firing in known manner by pulverized fuel and primary air nozzles 14 separated by a secondary air nozzle 15 located at each corner is closed below by a pyramid shaped hopper bottom 5 the walls 6 of which merge into the wall 7 of a tube lined cylindrical cyclone furnace chamber 8 suspended therefrom and coaxial with the chamber 1 and having a cone-shaped bottom 10 with slag outlet 11. If desired the chamber 8 may be shaped to widen upwardly in conical fashion. The outlet 11 leads to slag removal means having gas tight connection with the chamber 8 and including a trough 12 conveniently suspended either from the chamber 8 or directly from the bottom 5. The trough is partly filled with water in which a scraper conveyer 13 operates. The chamber 8 is provided with a primary air and fuel nozzle 16 and secondary air nozzle 17 all of which are so tangentially arranged as to produce a whirl in the same direction as that produced in chamber 1. When necessary the firing of chamber 1 may be discontinued the necessary combustion of fuel then being carried out by the cyclone furnace alone. When the latter is operating alone it may be used to light up the burners in chamber 1.
