Patent GB-645086-A (GB)
Title: Aliphatic olefins and cyclic process for manufacture thereof
IPC: C07C2/18
Filed: 1948-03-23
Abstract: In the preparation of polymeric olefins boiling above about 325 DEG F. and below about 520 DEG  F. by contacting propylene with an acid polymerization catalyst in a polymerization zone, separating a lighter olefinic fraction boiling below said polymeric olefins, recycling said lighter fraction to the polymerization zone, and recovering said polymeric olefins boiling above 325 DEG  F., decline in conversion rate to said higher boiling polymers is inhibited by rejecting a fraction comprising saturated hydrocarbons formed in said polymerization zone. Saturated hydrocarbons may be removed from the entire product or part thereof, such as the recycle stream.  Thus part of said stream may be bled out.  More selectively, saturated hydrocarbons are removed by liquid phase solvent extraction or unsaturated hydrocarbons are separated from them by adsorption on silica gel or the like.  Alternatively, C5 and lighter saturated hydrocarbons are removed by fractionating the product, and C6 and above are recycled and suppress additional formation thereof.  Part of the C5 may be recycled also.  Preferably the process is applied to the interpolymerization of propylene with an acyclic C6 to C11 olefin with a phosphoric acid catalyst as in Specification 638,514, and operating conditions are otherwise as described in the said Specification as is the conversion of the olefins to alkyl sulphonates, alcohols, phenyl alkanes and alkyl phenols.  Diolefins may be eliminated before conversion to monophenyl alkanes by silica gel adsorption or the mixture used to form mono- and di-phenyl alkanes which are then separated by distillation.  Results of measurements of infra-red absorption which indicate the structure of the polypropylene products are given.

Title: Improvements in and relating to electromagnetic switches for lighting installations of vehicles especially of automobiles
IPC: H02J7/14
Filed: 1950-04-06
Abstract: 667,517. Electromagnetic switches. BOSCH GES., R. April 6, 1950. [April 9, 1948] No. 8694/50. Class 38 (v). [Also in Group XXXV] In a lighting system for vehicles wherein the lamps are supplied with current, when the vehicle is in motion, from an A.C. generator, an electromagnetic switch, adapted to switch the lighting from the generator to the battery and vice versa, has a 'current' winding 36 and a 'voltage' winding 37 which act conjointly and substantially without opposition on the armature 31. The generator has a winding 11 for charging the battery 13 through a rectifier 12 and a winding 10 which, when the vehicle is in motion, energizes the windings 36 and 37 in series so that the armature 31 is attracted, whereupon if the lighting switch 15 is closed, current also passes from the winding 36 through contacts 33, 32 and the armature to the lamps. The magnetic circuits of the coils 36, 37 are substantially independent of each other and the fluxes are in phase with each other when the lighting circuit is not closed. Falling away of the armature at the zero point is, however, prevented by the short-circuited windings 39. When the lighting circuit is closed, the flux of winding 37 is displaced in phase by about 90 degrees relative to flux of winding 36 and there is no resultant zero force on the armature.
