A water soluble or swellable polymer gel is dispersed into a liquid phase to form a fluid composition and is worked while in that composition. The liquid phase is an aqueous solution of an equilibrating agent that substantially prevents aggregation of the particles or dissolution of the polymer during the working. The working may be, for instance, milling, extraction of impurities, extraction of w...

Addition-crosslinking compositions based on polysiloxane, containing a) an organopolysiloxane containing two or more vinyl groups in the molecule, b) an organopolysiloxane containing no reactive groups, c) an organohydridopolysiloxane as crosslinking agent, d) a catalyst for accelerating the addition reaction, e) optionally inorganic fillers, f) optionally organic st...

Multifilament superconductor strands of less than 1 mm diameter able to carry alternating current are stranded to a pitch of between 7 and 3 diameters, at a temperature above 200 DEG C. and a speed between 30 and 5,000 rpm.

A retention article for retaining closely-spaced terminals in a connector housing is formed having a stiff water-like article of thermoplastic material and elastomeric material therearound, with a plurality of holes extending therethrough. A pair of arcuate, partly converging wall sections partly surround each hole of said water-like article and extend forwardly from a planar section thereof havin...

The string tensioner wheel is supported by an arm which is so arranged that it can move in different directions to reach each required point on the racquet frame.

The present invention concerns a float device which prevents the fish from "escaping" after being hooked. The float device includes a means which is triggered when a fish moves on the hook or, to be more exact, jerks its head on the hook. The means causes the hook to be pulled slightly upwards, thereby fastening in the upper jaw of the fish. This has been made possible by arranging pins 9 on the s...

All the components of the ventilation unit are housed in a rectangular casing and include an inlet fan (12), exhaust fan (13), heater battery (16) and, if required, a filter unit. Exterior fresh air is supplied to the room and vitiated air is extracted from an intake at ceiling level. - The vitiated air is passed through one section (15'') of a regenerative heat exchanger (15) whose mass is thus h...
