A process for the treatment of a soft contact lens, to increase its resistance to the deposition thereon and diffusion and accumulation therein of substances which will promote its clouding and discoloration in use, and to improve its mechanical strength, includes treating a hydroxyl group-containing acrylic ester soft contact lens or replica with an organic acid anhydride for a sufficient period ...

A cross-country ski binding for cross-country ski shoes which have, at their front sole end, engagement elements which correspond with and engage into engagement elements of the ski binding, to provide a pivot connection. The ski binding has a U-shaped clip or stirrup member for securing the front sole end against lifting off the ski binding engagement elements, the legs of which clip are mounted ...

High strength and modulus articles of polyvinyl alcohol are obtained by thermoreversible gelation of a polyvinylalcohol solution, extraction of solvent using a mixture of a lower alcohol or ketone and water, followed by high stretching. Pref. a mixture of 5-80 vol.% of acetone and 95-20 vol.% of water is used as extractant. With this process extraction times of only 3-10 minutes are needed.

Stable suspensions of water-soluble polymers in a nonsolvent hydrocarbon medium, their preparation and their use for improving the assisted recovery of oil are described. These suspensions consist of at least one aliphatic or aromatic liquid hydrocarbon which is not a solvent for water-soluble polymers, into which there are introduced (per 100 parts by weight of the said liquid hydrocarbon) from 0...

Process for the preparation of a combined mixture based on silica and a polymer with a view to an application for reinforcing elastomers. The process is of the type in which a silica derivative is introduced into an emulsion of natural or synthetic elastomer latex and is characterised in that the silica derivative is first of all mixed with a first latex based on a compound of a vinylaromatic mono...

An article surveillance system includes a structure responsive to a first pulsed inductive magnetic field, periodically derived by a power line activated generator. The structure derives a second pulsed inductive magnetic field having a predetermined occurrence time relative to the occurrence time of the first magnetic field. A receiver for the second magnetic field is power line activated. The oc...

PURPOSE:To synchronize efficiently a digital signal of an optional bit rate by dividing a signal into a synchronizing part and an asynchronizing part and coding the asynchronizing part only into a code corresponding to 1, 0 and Empty and synthesizing the result with the synchronizing part. CONSTITUTION:An original signal S0 is fed to an input terminal (a) of a buffer memory 1. A written signal is ...

Miniaturized current sensing transformers are electrically and mechanically attached to the printed wiring board carrying the electronic trip unit circuit within molded case circuit breakers. Electrical contacts extending from the current sensing transformers project through openings in the wiring board to springingly engage metal posts extending from the printed wiring board surface. Notched post...
