Title: Improvements relating to the manufacture of olefin polymers
IPC: B01J27/06
Filed: 1957-08-08
Abstract: A polymerization catalyst comprises solid particles of a lower halide of titanium or zirconium partially embedded in a solid carrier.  The carrier may be sodium aluminium chloride, thallium oxide, iron chloride, gallium chloride, elemental sulphur, or an alloy such as solder, type metal or Wood's metal.  The polymerization is carried out in an inert, liquid hydrocarbon reaction medium containing a catalyst activator such as an alkyl derivative of aluminium, zinc, beryllium, chromium, magnesium, lead, lithium, sodium, or potassium, or a metal hydride, a metal borohydride, or an alkyl metal halide. In an example propylene is polymerized in n-heptane containing aluminium triisobutyl using a catalyst obtained by melting sodium aluminium chloride, dispersing particles of titanium trichloride on the surface of the melt, and then rapidly cooling so that the particles are partially embedded in the surface.  In another example, sodium aluminium chloride is melted, titanium trichloride is mixed with the melt, which is cooled, crushed, and dispersed in iso-octane, and propylene is passed in.ALSO:Gaseous olefins, such as ethylene, propylene or mixtures thereof, are polymerized in the presence of a catalyst comprising solid particles of a lower halide of titanium or zirconium partially embedded in a solid carrier.  The carrier may be sodium aluminium chloride, thallium oxide, iron chloride, gallium chloride, elemental sulphur, or an alloy such as solder, type metal or Wood's metal.  The polymerization is carried out in an inert, liquid hydrocarbon reaction medium containing a catalyst activator such as an alkyl derivative of aluminium, zinc, beryllium, chromium, magnesium, lead, lithium, sodium, or potassium, or a metal hydride, a metal borohydride, or an alkyl metal halide.  The olefin is polymerized at a temperature between 0 DEG  and 170 DEG  C., and at a pressure between atmospheric and 5,000 p.s.i.g.  In an example, propylene is polymerized in n-heptane containing aluminium triisobutyl using a catalyst obtained by melting sodium aluminium chloride, dispersing particles of titanium trichloride on the surface of the melt, and then rapidly cooling so that the particles are partially embedded in the surface.  In another example sodium aluminium chloride is melted, titanium trichloride is mixed with the melt, which is cooled, crushed, and dispersed in isooctane, and propylene is passed in. Olefin/diluent solution may flow over a fixed bed of catalyst or the catalyst may otherwise be dispersed in the solution.  The polymers obtained may be removed from the surface of the catalyst by scraping and washing with heptane, or by dissolving the catalyst and carrier in a suitable solvent, e.g. water or inorganic acid such as HCl, followed by separating the polymer and washing same with methanol.

This causes an excess pressure in the artificial kidney which sets off an alarm signal of the control units.

Abstract: The invention comprises dyestuffs of formula <FORM:0818008/IV (c)/1> where X is H or -N=N-R1 and R and R1 are residues of diazo components of the benzene, naphthalene or stilbene series. This may be made by coupling the copper coupler of an appropriate naphthalene-azo-naphthalene dyestuff with the desired diazo component.  The copper complex of the naphthalenic starting material may be made by reacting 2-diazo-1-hydroxy - 5 - o - benzene - sulphonyloxnaphthol - 7 - sulphonic acid with an appropriate ammoniacal copper salt solution and saponifying the product.  When the products are derived from diazo components containing complex-forming groups such as the salicylic acid grouping and those in o-position to a diazo group, they may be metallized in substance or on the fibre.  Indicated diazo components and anilines, o-aminobenzenecarboxylic acids, 1-amino - 2 - methoxybenzenes, naphthylamines, 4-aminoazobenzene sulphonic acids and 4-amino - 41 - nitrostilbene - 2,21 - disulphonic acids.

Abstract: 485,449. Endless - belt conveyers for feeding bottle - washing machines. EBBEDAL, N. J. O. J. Sept. 22, 1937, No. 25718. [Class 78 (i)] A method of supplying bottles to washing machines of the kind in which the bottles are moved along while inserted in cells disposed side-by-side in wide washing conveyers which are moved step-by-step and to which a number of bottles corresponding to the width of the conveyer are supplied whenever the conveyer stops, is characterized in that the bottles are supplied to the washing conveyer from several conveyers, each of which delivers, for each step, only that fractional part of the number of bottles to be delivered, which corresponds to the number of conveyers. In the embodiment shown, the bottles, after being deposited on a table formed by chain conveyers, are divided into two streams by a V- shaped member and fed forward by conveyers 4. They are then transferred by discs 17 to conveyers 18, 19 disposed at right-angles to the washing conveyer 24 opposite one end thereof. These conveyers each convey one half of the bottles to be supplied to the conveyer 24 at each step, the conveyer 18 extending to the centre of this conveyer and the conveyer 19 extending along its entire width. The bottles are then discharged in rows into cells 37 of a cradle mounted on a pivot 36, by a slide 26 which is reciprocated on guides 27 by arms 28 actuated through an arm 30 by a cam 31. This slide consists of bars 32, 33 fitted with bottle-removing plates 34, 35. The cradle is tipped towards the conveyer 24 through a linkage 44, 45 actuated by a cam 47, and the bottles, lying on their sides, are pushed into the cells 25 of the conveyer 24 by arms 41 striking them at one end.

Abstract: 646,272. Control of two motors. ROTAX, Ltd. Oct. 4, 1948, No. 25784. [Class 38(iii)] When one of the motors a, b, runs faster than the other, it is brought to rest until proper co-ordination has been restored by continued movement of the other motor. As shown, the motors have oppositelywound series field windings c, d and e, f. Motor a drives contacts j, k, which are mounted at a fixed angle and co-operate with a stationary commutator comprising continuous rings g, h, and segmental ring i. Motor b drives contacts p, q, of a similar commutator, the two sets of segmental rings being inter-connected. During operation, the armature and the effective field winding of each motor is connected in series with contacts on the two commutators, and, when the motors rotate in step, the contacts j, p, and k, q, occupy corresponding positions. If, for example, the contact sdriven by the motor a advance relatively by 120 degrees in the clockwise direction, that motor is stopped, since its circuit is broken at the commutator operated by the motor b, until the difference between the angular positions of the sets of motor-driven contacts is removed. A selector switch t provides reversible action. The motors may be adapted to operate a pair of control flaps on an aircraft in unison.
