Title: Process for the manufacture of ª--olefine polymers
IPC: C01G23/02
Filed: 1958-04-28
Abstract: C3-8 a -olefins such as propylene, butene-1, 3-methylbutene-1 or styrene are polymerized to products of more than 90% isotactic content, by use of a solid catalyst prepared by reacting an alkyl aluminium halide with TiCl4 in a reaction medium in the range of - 20 to + 40 DEG  C. and in molar ratio of 0,5 to 2:1 and then heating the catalyst at 40-150 DEG  C., which catalyst is activated with an organoaluminium compound, preferably an alkyl aluminium halide.  The catalyst may be separated from the reaction medium and washed with an inert solvent, before or after the heat treatment; or the latter may be carried out by washing the catalyst with inert solvent at a raised temperature. Optically, the heat treatment is effected in presence of diphenyl ether, tetrahydrofurane, dioxane, sodium chloride or an organoaluminium compound.

Title: Improvements in barometric pressure sensitive systems
Filed: 1941-10-24
Abstract: 617,953. Automatic control systems. SPERRY GYROSCOPE CO., Inc. Oct. 24, 1941, No. 13718. Convention date, Oct. 30, 1940. [Class 38 (iv)] A barometric bellows used to control the altitude of an aircraft is opened to the atmosphere upon excessive pressure difference and is compensated for temperature changes. Before use, both ends of the bellows 1 are free to move and bimetallic strip 3 moves the left-hand end so as to keep contact 7 centralised between pick-up contacts 8, 9 carried by bimetallic strip 11. Closure of switch 32 brings the bellows into action by energizing coil 28 to cause arms 30, 31 to grip tube 6<SP>1</SP> and fix lefthand end of bellows and also close port 27 so as to seal the bellows. Thereafter reversible motor 15 causes contacts 8, 9 to follow movement of contact 7 and drives shaft 23 which is connected to an automatic elevator control as in Specification 416,813. Excessive movements of the bellows causes cam 35 to open contacts 37 and thus de-energize coil 28. In one modification the motor 15 effects the repeat-back action by moving the support of the strip 3, and in another modification by altering the volume of another bellows pneumatically connected with the bellows 1. Temperature compensation can also be effected by further bellows operated by a bimetallic strip. A dash-pot can delay closing of port between the inside and outside of the bellows and the operation of a clutch between the motor and the elevator controlled until the motor has had time to centralise the contacts. Specification 416,813, [Group XX], is referred to.

Filed: 1925-05-27
Abstract: 234,818. Kalle & Co. Akt.-Ges. May 28, 1924, [Convention date]. Plates, films, and papers. - Instead of using diazo anhydrides as described in Specification 210,862, sensitive layers are formed by using azo dyestuff coupling components in conjunction with diazo compounds not coupling per se in an acid or neutral condition with the coupling component either in the light or in the dark, the sensitizing solution being in an acid or neutral condition. On exposure to light the diazo compound is decomposed and on development with alkali, coupling between the non affected diazo compound and the coupling component takes place. Positives are accordingly directly reproduced from positives. The developing alkali may be gaseous (i.e. ammonia). Metallic salts may be added or metallic salts of either or both components may be used. Diazo compounds mentioned are the amino-diazo compounds, for instance, the diazo compounds from p-diamines and their derivatives, such as from aminodiphenylamines (e.g. phenyliminoquinonediazide or from o-dialkylaminoaniline and its sulphonic acid, also the diazonium salts of carbazole and fluorene.
