PURPOSE:To obtain the titled extremely stable dispersion, homogeneously dispersible in various solvents even using no surfactant, by dispersing low-molecular weight fluorine-contg. resin powder of specific particle size in an organic solvent. CONSTITUTION:The objective dispersion can be obtained by dispersing (A) low-molecular weight fluorine-contg. resin powder with an average particle size of <=...

A process for the production of a mixture of a polymer and a fibrous material, which comprises agitating an aqueous solution of a coagulant for the polymer; adding an aqueous suspension of the fibrous material to the coagulant solution; adding the polymer, in aqueous latex form, to the coagulant solution; co-coagulating the polymer and the fibrous material; and recovering and drying the mixture of...

Foams are prepared from a linear low density polyethylene and, optionally, other olefinic polymers, such as a low density polyethylene using a chemical cross-linking agent. The resulting cross-linked polyethylene foams exhibit an excellent balance of properties at generally lower densities than foams prepared from low density polyethylene only.

The horizontal sync signal contained in the video signal from a video apparatus sometimes undergoes phase jump, resulting in failure of multiplexing of audio and video signals based on the horizontal sync signal. A sync signal switching circuit is adapted to produce a modified sync signal by switching the sync signal to a local sync signal upon occurrence of the phase jump, thereby assuring the mu...

The invention relates to a magnetic core for a transformer or the like, which core is made of different ferromagnetic materials. The core is a composite constructed of ferromagnetic circuits (22, 24) nested one within the other and comprising at least one circuit (22) formed of a grain-oriented electrical steel, and at least one circuit (24) formed of a ferromagnetic amorphous material. Prefe...

PURPOSE:To raise the safety of a slewing type working vehicle by a method in which pulse signals from a rotary encoder are measured by a counter circuit, and only when approximate values are obtained two times or more during the time of reading the measured values three times or more, the values are regarded as true ones and the working vehicle is automatically stopped. CONSTITUTION:A rotary encod...

PURPOSE:To form a water-proof coat with a durable uneven pattern by applying under coating and intermediate coating materials of specific silicon resin respectively on a building wall. CONSTITUTION:As under-coating materials, silicon modified organic resins which are reaction products between silane or silicon resin and general organic monomers or organic resins are used. These materials smooth th...

An osteofiller is characterized by using columnar sintered hydroxy-apatite having at least one capillary tube passed therethrough in the vertical direction.

Method of reconditioning a water well, in particular a drinking- water or process-water well, in which a certain mortar is pressed only near to the damaged point through the already existing water-ingress slots (18) into a filtering-gravel layer surrounding the well tube against the static pressure of the penetrating ground water.

1. A process for the production of mouldings, especially cushions, from at least two foams, especially polyurethane foams forming fluid reaction mixtures of different elasticity or hardness, wherein a first and at least a second reaction mixture are introduced into a mould cavity and are left to react out to form a moulding having zones (4, 5, 8) of different elasticity or hardness before the moul...

The invention relates to a process for decreasing the content of nitrate in ground water, artificial ground water, that is infiltrated surface water, or surface water flowing through an aquifer or through a basin or a filter containing naturally occurring filter material. Water containing denitrification organisms and/or substrate therefore is introduced intermittently through a number of injectio...
