A method for catheter tipping includes applying to a catheter blank a layer of a noncuring aminoalkyl terminated polysiloxane lubricant, mounting the lubricated blank on a mandrel and advancing the mandrel-catheter assembly into a heated die so that the die causes the heated tip of the blank to assume the shape of the die. The catheter may then be cut beyond the shaped tip and easily removed from ...

An incision opening expansion holder for use surgical operation, especially for inosculation comprising an outer tube being capable of inserting into the lumen of a vein graft, an inner tube slidably inserting into the outer tube and a grip being fixed to one end of the inner tube, the inner tube has a plurality of short wires, the bases of which are fixed to the other end of the inner tube and ea...

Inspection of a circuit board (10) to detect missing and misaligned active and passive surface-mounted components (12) and (14), respectively, is accomplished by first illuminating the board with top light to enhance the image of the passive components. The circuit board is then displaced, relative to a linescan camera (28) trained on the board, so that the camera captures the image of successive ...

An apparatus for determining if a received binary word corresponds to the true or complement version of a stored binary word includes means for serially multiplexing the bits of each binary word to the inputs of an exclusive OR gate. The exclusive-OR gate generates a logical high signal each time a mismatch occurs. These signals are applied directly to an error counter and, after inversion, to a m...

A crosslinkable polymer composition comprises an olefin copolymer or graft copolymer with hydrolysable silane groups and a silanol condensation catalyst, as well as a silane compound with at least one hydrolysable organic group. The polymer composition is characterised in that the silane compound has a compatibility with the polymer composition of at least 0.035 mole hydrolysable groups per 100 g ...

Expanded styrene acrylonitrile polymer particles are provided which give good resiliency over an extended period of time.

In the manufacture of thermoplastically processable starch, an additive is essentially mixed with native or natural starch and the mixture is caused to melt by the application of heat and mechanical energy. The additive is a substance which lowers the melting point of the starch so that the melting point of the starch together with this additive lies below the decomposition temperature of the star...

A process for dispersing one or more powdered ignition resistant or flame retardant additives into carbonate polymers which comprises the steps of preparing a base concentrate having from 5 to 50 weight per cent of said additives by blending said additives with a carbonate polymer having a melt flow rate of from 3 to 20, pelletizing said base concentrate having said ignition resistant additive dis...

Polystyrene foam particles having a density of 10 to 30 kg/m<3> are obtained when styrene polymers containing 0.7 to 3 mol/kg of a blowing agent mixture comprising 60 to 90 mol% of water and 10 to 40 mol% of a C4- to C5-hydrocarbon are foamed using microwaves.

Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into a precipitating solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized. The beads may a...

It is sometimes desirable to cure rubber compositions utilizing non-sulfur curing agents. The subject invention reveals rubber compositions which can be cured without utilizing sulfur or sulfur containing compounds. The subject invention more specifically discloses a rubber composition which can be crosslinked by heating which is comprised of (1) at least one rubber having pendant blocked isocyana...

Aqueous emulsions of curable silicone compositions provide cured coatings having improved gloss and/or water-repellancy and/or adhesive release if formulated to contain polyvinylalcohol having a degree of hydrolysis of 90 mol% or more. The extent of improvement is directly related to the degree of hydrolysis of the PVA. PVA having an average degree of hydrolysis of from 94 to 99 mol% is particular...
