Disclosed is a closed-cell, non-crosslinked foam structure of a ratio of min or dimension to major dimension of 1/8 or less comprising a plurality of coalesced extruded strands or profiles of a foamed polyolefin composition having an average cell size of from 0.02 to 0.5 millimeters. The cross-sectional geometry of the foam structure substantially corresponds to the overall arrange- ment of the or...

A rubber composition for coating steel cords, comprising a raw material rubber and, compounded therein, a methylolmelamine derivative and a product of a reaction of a cobalt salt of an organic acid with a metaboric acid ester, and a rubber product reinforced with rubber-coated steel cords comprising steel cords coated with the rubber composition.

Stable aqueous microdispersions of finely divided polyamide resin particles and methods for the manufacture thereof are provided. The properties of these microdispersions are achieved by the addition thereto of an effective amount of a co-surfactant such as a lower alkyl alcohol. The provided microdispersions can be drawn into films which will form clear, continuous films at ambient or near-ambien...

For the application of a surface protecting layer of plastics onto heat transfer plates the plates are first assembled to a plate heat exchanger (1). After this a gaseous medium containing the plastic material, preferably in an evaporated state, is introduced into the plate interspaces. In a manner known per se the plastic material is caused to deposit onto the heat transfer plates in the plate in...

The invention concerns a process for cleaning exhaust air containing biodegradable contaminants which arc only slightly soluble in water. The contaminants are absorbed by a washing liquid containing activated sludge and at least one high boiling solvent for the contaminants and are decomposed by the activated sludge. The solvent and the activated sludge are separated from at least part of the rema...

2107123 9216165 PCTABS00016 A device which serves as an artificial pancreas comprises a hollow fiber (12) which is surrounded by islets of Langerhans (14) enclosed in a housing (22). The islets are suspended in a temperature sensitive matrix (25) which is sufficiently viscous to support islets at a temperature below about 45 ·C and sufficiently fluid to enable removal of islet suspension at a temp...

A rigid wall partition system which is vertically upwardly movable into storage position and vertically downwardly movable to form a continuous wall. The system comprises a plurality of panels secured to members which in turn are pivotally secured to spaced trains of single pantographs, contraction of the pantograph causing the panels to fold, in accordion fashion and expansion of the pantographs ...

The present invention is a unique antimicrobial composition which comprises an antimicrobial agent, a nonionic surfactant and an anionic surfactant. The composition is useful in providing antimicrobial effectiveness in surgical scrub applications with excellent mildness characteristics.

The invention relates to a process for preparing an alkane and/or alkanol by oxidizing an alkane with 3-30 C-atoms, us- ing oxygen, to form an alkyl hydroperoxide, followed by a decomposition of t he resulting alkyl hydroperoxide in the presence of a metal compound immobilized on a carrier, which carrier carries aliphatic o r aromatic amine groups or sulphide groups. The process is preferably app...

: Both the drying and also the removal of the water crystalization take place carefully in a respective fluidized bed apparatus (A, B) without any danger of overheating. This is achieved by a complete homogenous fluidization through indirectly heated hot gas. A substantial quantity of energy is transferred via heat exchanger systems (4 or 12) in the fluidized layer. These are heated by heat carryi...

Apparatus and method are described for controlling thickness of plastic films produced by the blown film process. The apparatus is an air cooling ring modified to include devices for locally modifying the temperature of the air discharged from the air ring onto the blown bubble. Local variations in the temperature of the cooling air applied to the surface of the bubble result in variations in the ...

A cellular telephone system includes a packet-switched digital data communication subsystem overlaying a circuitswitched (e.g., voice) communication subsystem, with voice and data services sharing the same voice channels. The voice communication subsystem provides voice services independently of the operation of the data communication subsystem. On the other hand, the data communication subsystem ...

A method and apparatus for the alignment of paper stacks in a printing press provides essentially uninterrupted printing through the transfer of supply of sheets of paper from a first stack of papers to a second stack of papers by reducing mechanical strain in the control and operation of the sheet feeder of the printing press.

The manufacturing method for semiconductor device comprises (A) forming gate oxide film, gate, gate side wall, source and drain region on a given area of semiconductor substrate, (B) coating thereon with a first oxide film and making a contact window, (C) successively depositing pad polysilicon and a second oxide film thereon, (D) etching pad polysilicon and the second oxi...
