A process for controlling bead size in the manufacture of expandable styrene polymers by suspension polymerization, wherein, referred to the aqueous phase, a concentration of ions of calcium, aluminum, metals of the 1st, 2nd, or 6th through 8th side groups of the period table of elements of 3x1031 5 to 3x10-2% by mass is established, these metal ions being present as cations in the higher oxidatio...

A process for controlling bead size in the production of expandable styrene polymers by suspension polymerization is carried out by adding protective colloids to the aqueous phase before polymerization begins, such protective colloids being used which are homogeneously soluble in water over the entire temperature range from 25 DEG to 125 DEG C. and in which the concentration range being employed...

A surface-grinding device, with a mounting support which can be fastened to a work bench or the like, a vertical grinding disc (4), and a guide table (8) which is equipped with a guide stop (10) pivotable on the table surface and lockable in the respective oblique position, is to be designed in such a way that the full surface of the grinding disc (4) can be utilised when grinding a workpiece whil...

To obtain better quality plastisol processing powders, VC homo and copolymer dispersions produced by emulsion or microsuspension polymerisation are subjected for a period of 1-60 minutes to an electric field characterised by the conditions grad E = 600-1000 N/As and dl/dA = 1-10 mA/cm<2>. Less than 35% of the solid is precipitated on the electrodes and is treated separately, the remaining latex be...

Inertial measurement of the angular rotation and translational motion of a structure can be provided by a pair of vibrating accelerometers 10, 12 aligned in a side-by-side arrangement with their force sensing axes A<1>z, A<2>z in the same plane and vibrated to and away from each other in that plane along an axis normal to their force sensing axes.

In a lighter for solid fuels, such as coal, wood or the like, consisting of a framework of foam plastic and a fuel of low volatility, in particular petroleum, bonded thereto, the proportion of petroleum is reduced, if the framework consists of foamed polystyrene, in order to reduce the production cost without impairing the lighting behaviour and the formation of embers.

Apparatus for dispersing polymer powders, such as shown by the figure, comprising a funnel (1) with central filling inlet (2) in whose upper portion at least one tangential liquid inlet (3) is arranged, a funnel outlet tube (4) with annular nozzle (5) and a downstream jet pump (6), and process for dissolving polymer powders, characterised in that the polymer powder is dispersed in the apparatus de...

In repairing articles of natural rubber or elastomer predominantly of natural rubber with cured polymer or prepolymer (polyurethane/polyurea), adhering advantages are obtained especially at elevated temperatures when the damaged area is treated with halogen-containing oxidant dissolved in 1,2-dichloroethane instead of other solvents.

The invention relates to a coating composition for the preparation of the base coat of a multilayer enamel consisting of at least one base and one transparent protective coat, the said coating composition containing binders based on organic resins, metallic pigments, organic solvents and, if appropriate, other pigments as well as customary additives and auxiliaries. The coating composition contain...

The glass parts comprise oxidic glass and have at least one surface layer which is at most 300 ANGSTROM thick and has a composition with a substoichiometric amount of network-forming and/or network-modifying ions compared with the oxygen ions. The film used to join the glass parts comprises polyethylene, has a thickness of from 5 to 100 mu m and has been modified on the surface by treatment wit...

The present invention is a data processing system which has plural operation units which can execute plural instructions in parallel. The system also has plural instruction control units each of which comprises at least two stages, one for reading source operands from a local storage, and another for writing a resultant operand into the local storage. Each instruction control unit is provided with...

A composite filler obtained by precuring the acrylate or methacrylate of a polyhydric alcohol having at least three ethylenically unsaturated groups in the molecule thereof by using a free-radical initiator in the presence of an inorganic filler, followed by grinding the resultant prepolymer is described. This composite filler remarkably improves the stiffness and hardness of organic resins and ru...

Irradiation device, especially for whole-body irradiation of individuals, essentially with UV-A radiation. The irradiation unit is formed by an independent, self-supporting structural unit having two essentially shell-shaped outer parts, one of which is permeable to radiation while the other is impermeable. Tubular emitters are arranged between the shells in parallel to and at a specific distance ...

The coupler allows the electrical heating wires for a motor vehicle window also to be used as a radio aerial. The coupler separates the HF signal from the heating current. The DC heating current is applied via an inductive HF-decoupling circuit to the heating wires (3) in the window. The HF signal passes via an LC filter and DC-decoupling capacitor to an HF output terminal. Various configurations ...
