Abstract: 1490597 Windscreen wipers WYNSTRUMENTS Ltd 13 Feb 1976 [5 Sept 1975] 36554/75 Heading A4F [Also in Division E2]  A window or windscreen wiper driven by an endless flat drive belt 3 rotatable around pulleys 4, 5 is coupled to the belt by a device comprising an element 20 connectable at pivot 19 to a link 17 and having a part-cylindrical surface 23, and a clamp part 25 which extends through an aperture 24 so as to define a slot 28 with the surface 23 in which the belt is clamped. As shown the clamp part 25 has limbs 27'to compress the width of the belt so that the device does not foul the pulleys 4, 5. Portions 29, 30 of resilient material, if positioned in the slot 28, spread local pressure on the belt 3 and prevent chafing of the belt. As shown the link 17 is pivotally attached to a carriage 7 for the wiper 13-16, the carriage being guided by rollers 8, 10 so that as the belt rotates around the pulleys 4, 5 the wiper blade 16 moves rectilinearly to and fro.

Title: Recovery of polymer from solution
IPC: C08F10/00
Filed: 1955-10-31
Abstract: Linear polyolefins are recovered from solution in a saturated hydrocarbon by vaporizing a substantial portion of solvent at a temperature above the melting point of the polymer, followed by vaporizing most of the unvaporized solvent at a temperature below the melting point of the polymer, and then heating and mixing the solid residue at a temperature greater than the melting point to remove the remaining solvent.  The first two vaporization steps may be carried out in vacuum flash tanks as is illustrated in a continuous flow process described with reference to the drawing accompanying the Specification.  The polymers and the production and applications thereof may be as disclosed in Specifications 790,195 and 804,641, and in addition the process is said to be applicable to the recovery of polyisobutylene, halogenated polyethylene and hydrogenated polybutadiene.  Solvents specified are cyclopentane, cyclohexane, methylcyclopentane, methylcyclohexane, hexane, heptanes, octane, nonane and trimethylpentane and the use of other solvents is also described. Recovered solvent may be combined and recycled to the polymerization process.

A magnetic core structure comprises magnetic laminations supported by a non-magnetic metal support, the parts having been annealed at the same time. As shown (Fig. 2) a non-magnetic metal ring 10 is provided with an outer groove into which a metal tape 13 is wound. Windings such as 15 may be provided on the core and the device may be used as a magnetic amplifier or a storage element. The Specification discloses a table of dimensions suitable for the core structure. The magnetic tape may be of 50-50 nickel iron, 4-79 Moly Permalloy, or ferrite and may have a thickness of “ or # mil. and is coated with insulating material before being wound. The support 10 may be stainless steel, specified alloys or titanium and is chosen so as not to contaminate the tape during annealing.
