In order to improve the flame protection effect without substantially impairing the mechanical properties of the articles covered with the flame protection agent, the flame protection agent is provided with a compound in a proportion by weight of 7.5 to 30% which contains at least one sulfo group or sulfonium ion. This compound is preferably a water soluble ammonium salt. As binder there is used a...

A process is disclosed for producing free-flowing pellets of ethylene terephthalate oligomer. In the process a molten ethylene terephthalate oligomer having an intrinsic viscosity of from about 0.08 to 0.15 is forced through a plurality of orifices of an orifice plate under pressure into an inert gas zone to form jets of the oligomer which dissociate into spherical droplets under the influence of ...

An improved coupled yeast-enzyme coimmobilisate is disclosed which results from the coupling in a jacketlike manner of one or more enzymes to the living fermentable cells of a yeast. The cells are normally partially or entirely dehydrated and subsequently rohydrated by means of an aqueous enzyme solution. An enzyme precipatating solution which does not inactivate the fermentative action of the yea...

A hydrodynamic brake apparatus having multiple stage rotor and stator assemblies housed within a main body. A shaft is journaled to the main body and connected to the rotors, so that power input to the shaft is dissipated by the reaction of the hydraulic fluid contained within the main body. An impeller connected to the shaft forces fluid to flow outwardly to the outer marginal end thereof where t...

Forming polystyrene foam by extruding polystyrene, nucleating agent, physical blowing agent, and water where the physical blowing agent and water are injected into extruder to provide blowing system. The product produced has small cells at junction points between membranes of the foam.

Fibers prepared by spinning, drawing and drying dilute solutions of ultrahigh molecular weight polyethylene or polypropylene are modified by including in the dilute solution a polymeric additive. The polyethylene fibers so prepared have melting points above 140 DEG C. and exhibit improved adherence to matrices, resistance to fibrillation and other advantageous properties. Additives include lower ...

A rubber composition having improved green strength is made by mixing chemically similar blends together and forming a heterogeneous blend. Generally, one of the blends called a minor fraction has a smaller amount of the primary components therein such as rubber and carbon black.

A method in the manufacture of steam-cured light-weight aerated concrete having hydrophobic properties, comprising preparing an aqueous expandable and solidifiable slurry, one or more hydraulic binders and one or more silica-containing materials casting the slurry in a mould; expanding and solidifying, and optionally cutting the solidified slurry; and steam-curing the resultant light-weight aerate...

A method and apparatus for coating a hollow article with at least two coating materials, said method comprising the steps of applying a first coating material to the article and drying or partially curing at least the surface of the first coating before the application of the second material. Thereafter the two coatings may be fully cured together or alternatively the second coating material may b...

A polycrystalline silicon field plate underlies a polycrystalline silicon resistor and is heavily doped so that it is virtually a conductor while an aluminum field plate overlies the polycrystalline silicon resistor. Electrical potentials are applied to the polycrystalline field plate and the aluminum field plate, the potentials being selected so that an electric field is created at the boundary b...

Capacitors or dual layer metalization interconnects are formed in an integrated circuit utilizing two layers of polycrystalline silicon (22, 24) separated by a thin insulation region (23). The insulation region formed between the two polycrystalline silicon regions has substantially fewer defects than the insulation regions used in prior art techniques due to the use of a unique process wherein th...
