A process for treating plastisol-type vinyl chloride resins having small particle size and relatively little capability for absorbing plasticizers such that the plastisol absorbing capabilities of the resins are improved. The preferred process is the treatment of the particles with water at a temperature which is not less than about 150 DEG F (65.6 DEG C) for a period of time sufficient to cause t...

The present invention relates to polyvinyl chloride resin particles which are colored with cationic dyestuffs, to a process of making them, and to plastisols produced therefrom. Resin particles are preferably heated in a solvent medium which preferably is water or comprises water, the solvent medium being suitable to dissolve the cationic dyestuff. The dye penetrates and dyes the particles. Partic...

1. A method of coating insulations against heat or cold having a basis of hard polyurethane foams, to improve the fire behaviour of the insulations, where the insulations are coated in a first process stage, with a dispersion-bonded, solvent-free, non-porous and elastic coating medium, which seals off the foam and contains inorganic pigments, fillers and/or fibres with various flame-inhibiting add...

A phenol derivative of the formula NU-A-X-R1 wherein NU is a defined bis-phenolic nucleus including a hydroxyphenyl-hydroxynaphthyl; hydroxyphenyl-hydroxyindanyl, hydroxyphenyl-hydroxybenzothienyl or di-hydroxyphenyl-ethylene or vinylene nucleus; wherein A is alkylene, alkenylene or alkynylene which may be interrupted by phenylene or other linkages, wherein R1 is hydrogen, or alkyl, alkenyl, cyclo...

Compounds of the formula I wherein C1 and N4 are in trans configuration to each other, wherein R and Y are defined herein below, as bases and pharmaceutically acceptable acid addition salts thereof, processes for their preparation and pharmaceutical preparations and methods of treatment employing such compounds. The compounds are useful for treatment of disorders in the central nervous ...

A device for effect regulation of an after-warming apparatus (1) which is designed to receive a flow of pre-treated air from a central pumping unit (2) and to separate and distribute after-warmed extra air flow to different rooms (8). The after-warming apparatus (1) has a manoeuvring device (6) for manual regulation of the heat supply, between, on the one hand, the apparatus's heat control (5) for...

The present invention is related to a pharmaceutical product preferably in medical bandage form, for the controlled release of a therapeutically active agent or several such agents to the skin. The pharmaceutical product of the invention consists of an impermeable backing layer, a particularly composed supersaturated reservoir layer for the therapeutically active agent connected therewith and comp...

Improved antithrombogenicity results when heparin is attached to a polymeric surface activated by treatment with a plasma. The surface thus activated is rendered receptive to the binding of a surface active agent. The surface active agent in turn reacts with heparin to provide a polymeric surface of exceptional antithrombogenicity when contacted with blood for an extended period of time.

The machine has a wheeled chassis containing a shaft which is open at top and bottom. The chassis contains blades (13) disposed on a rotary spindle (10) and extended away from it by centrifugal force so as to cut away the silage underneath. The latter is projected against a wall (30) of the shaft and out through the top opening (8) of the shaft.

Oxypulp from the oxytower is diluted with recovered oxylye to achieve a suspension of 60kg oxypulp per m3. The oxylye residue diffuses out from the fibrous mass to the surrounding liquid during a process interuption of at least 5 mins, without liquid exchange. The suspension is stirred for 30-90 mins. Weak oxylye leaves the treated oxypulp which is then washed. The diffusion stage is operated unti...

The conveyor belt 1 consists of a rough belt 5, on whose top side there are vulcanised dogs 7 situated transverse to the lengthwise direction of the belt. The dogs are moulded in a cover layer 11 of crude rubber, which is vulcanised on the surface of the rough belt 5 in the entire width of the belt 1. The dogs are placed in a region around the centre of the conveyor belt 1 that is slightly broader...

New intermediates and processes for preparing 6-halo-7,8-dihydroxy-1-(p-hydroxyphenyl)-2,3,4,5-tetrahydro-1H-3-benza zepines involve the reaction of a p-methoxyphenylglyoxal, lower alkyl hemimercaptal with a 2-chloro-3,4-dimethoxyphenethylamine, followed by a borohydride reduction.
