An impregnation-printed molded article comprises an article molded of a composition consisting of a thermoplastic polyester resin (A) and, in mixture therewith, a thermoplastic polymer compound (B) containing as a polymer skelton component unit at least one kind of material from the group consisting of butadienes, styrenes, acrylonitriles, and acrylates, said molded article being impregnation-printed.

A support material for cell impregnation is provided. The support material is fabricated from a semiabsorbable composite yarn comprising a nonabsorbable, elastic core yarn and an absorbable, relatively inelastic sheath yarn. A prosthetic device may be formed from the support material. The support material is impregnated with living cells followed by incorporation into the tissue structure of a host organism. The support material impregnated with cells may be cultured in vitro to increase the num...

A capacitor in which the capacitive element is impregnated and encapsulated by a composition having a softening point above the normal operating temperature of the capacitor and below the temperature that would occur following a failure of the capacitive element (or in another aspect below the temperature at which the polypropylene film of a polypropylene film capacitor shrinks). In other aspects the composition is a blend of polybutene and polyethylene; and a method of impregnating a capacitor ...

A method for the impregnation of wood to prevent attack by harmful agents such as decay fungi or mould fungi and bacteria by the application of an aqueous solution of an alkali lignin modified into a water-soluble form. Impregnation takes place in two stages, these being an initial stage in which the aqueous solution containing the lignin still in its water-soluble form and with a pH not exceeding 10 is applied to the timber, and a second stage in which the lignin is fixed as a water-insoluble f...

The present invention is directed to a process for preparing a cathode active material consisting of a single phase of mixed metal oxide, such as a single phase silver vanadium oxide. The synthesis technique involves first heating the starting materials to melt a decomposable starting constituent. This first heating temperature is held for a period of time sufficient to enable the decomposable starting constituent to melt and completely flow throughout and within the other starting materials. Th...

An improved method for preparing carbon-impregnated graphite bodies is provided comprising pulsing the graphite bodies between a vacuum atmosphere and a pressurized hydrocarbon atmosphere at elevated temperatures. The resulting graphite bodies, which are impregnated with pyrolytic carbon deposits, have helium permeabilities of less than 1 .times. 10.sup.-.sup.11 cm.sup.2 /sec.

A method to impregnate wood with a preservative, fire-retarding, stabilizing or the like wood treating agent, comprising compressing the wood across its grain for a short period of time, allowing the wood to recover from the compression and impregnating the wood with the agent while varying the pressure conditions of the wood environment.

A bundle of corrugated boards, having the fluted channels of the boards in substantially unidirectional alignment throughout the bundle are continuously advanced through an apparatus which comprises means for supporting the bundle, means for applying a compressive force against the outer surfaces of the bundle to maintain surfaces of adjoining boards in the bundle in tight abutment as the bundle advances, with at least a portion of the compression means forming the walls of a trough in the zone ...

The present invention relates to a digester and a method for continuously cooking kraft pulp in a single-vessel system (1), preferably a single-vessel hydraulic digester, with chips (2) being fed in at a first end (3) of the digester (1), white liquor (4) being added at at least one position at or near the said first end (3), the chips being impregnated in a cocurrent impregnation zone (5), the chips being cooked in a cooking zone (6) downstream of the impregnation zone, hot black liquor (7) bei...

The invention relates To a process for the impregnation of electrical capacitors which includes performing the impregnation of the coil winding with a dielectric fluid, eliminating the excess of the dielectric fluid, filling the casing containing the impregnated coil winding with a gelable composition and the dielectric fluid for impregnating the coil winding and gelling the gelable composition.
