Novel compositions of silicone/polyether block copolymers are provided which are useful as surfactants in several classes of polyurethane foam production. While conventional copolymers have a polysiloxane backbone with pendant polyethers, the surfactants of the present invention are the reverse with siloxane pendants on a polyether chain. These novel non-hydrolyzable polysiloxane polyoxyalkylene c...

A circuit is described for applying a potential to an electrode of a biosensing test cell, which electrode, when properly inserted in a female connector, is contacted by a pair spaced apart contacts. The circuit includes a source of excitation potential and an operational amplifier having one input connected to the source of excitation potential. A switching circuit is coupled between the operatio...

The addition of additives, in particular colourants, to polyesters such as polyethyleneterephthalate is achieved by dissolving or dispersing the additive into an ester of an alcohol and a substantially straight chained fatty acid having from C14-C22 carbon atoms. The advent of a liquid colourant has particular advantages to the food packaging industry. The preferred carrier is the ester of oleic a...

A polymeric film has a polyester substrate layer and an adherent layer of an acrylic resin and a phthalate ester. The adherent layer preferably contains an additional cross-linking agent. The adherent layer exhibits improved adhesion to the substrate and to a range of subsequently applied layers, such as inks and lacquers, vinyl chloride polymer.

A steerable rotary drilling tool includes a drill bit mounted on the lower end of a housing by a drive shaft having an articulative coupling that allows the bit's rotation axis to be inclined relative to the rotation axis of the housing, an eccentric weight in the housing that maintains the bit axis pointed in only one direction in space as the bit is turned by the housing, and a clutch system tha...

L'émulsion aqueuse de polyorganosiloxane, notamment pour l'enduction de matières textiles ou analogues, qui comprend une formule organopolysiloxane précurseur de l'élastomère comprenant un polydiorganosiloxane, de préférence une charge minérale, un catalyseur et éventuellement un réticulant, en l'absence de tensio-actif dans cette formule, se caractérise par le fait que la formule organopolysiloxa...

A press-through foil (2) for press-through packaging (1) is formed from a plastic mixture made up of such plastics that, in the melt and in the foil formed therefrom, they form at least two phases, that is non-homogeneities, so that the tensile strength and impact resistance are reduced. A packaged product can be appropriately easily pressed through this foil, but is completely sealed prior to tha...

A membrane comprising a non-porous separation layer o a polymer blend of a first polymer selected from cellulose esters and a second polymer selected from polyvinylpyrrolidone (PVP), copolymers of vinylpyrrolidone and vinylacetate (VP-co-VA), polyethylene glycol (PEG), N,N-dialkylated polyacrylic amides (DPAA) and cellulose esters other than said first polymer. The membranes are used for removing ...

Polymer and wood composite structural members are manufactured by extruding and injection moulding a composition comprising polyvinyl chloride, wood fibre and optionally a concentration of an intentionally added waste stream. Such structural members have strength, workability, fastener retention, resistance to rot and insect attack, and thermal properties sufficient to constitute an advanced compo...
