Patent SE-7606267-L (SE)
Inventor: ARONSON R R
IPC: H01M50/77
Filed: 1976-06-03
Abstract: A battery preferably for use as a power source in an electrical vehicle includes a plurality of envelope separators for reducing the concentration of waste products at the surface of the battery plates. The envelope separators comprise two thin sheets of microporous material which are bonded together at their edges and placed between each of the plates of the battery. The envelope separators while being nonconductive are highly porous thereby allowing electrical current to pass from one plate to the other through the separators in the electrolytic solution of the battery. The electrolyte is pumped into each envelope separator under pressure and is forced out through the pores or small holes in the sides of the envelope to flush water, gas and loose particles of active material away from the plates of the battery. By forcing the electrolyte against the plates of the battery, the concentration or specific gravity of the electrolyte at the surface of the plates is increased, thereby increasing battery efficiency.

A method for the determination of the quantity and type of a first biologically active component in a sample which is added to a well in a liquid-saturated, porous matrix covering a thin layer of a second biologically active component bound to the solid surface of a carrier. A third biologically active component included in the matrix is capable of reacting biospecifically with the first biologically active component when the sample is allowed to diffuse or migrate electrophoretically in the matrix forming a zone containing a precipitate of the first and third biologically active components. This precipitate will absorb with biospecificity to the second biologically active component, bound to the solid surface of the carrier and is visualized in a suitable manner on the surface after removal of the porous matrix, e.g., as a change in the surface tension angle observed with the aid of vapor condensation on the surface. The second and third biologically active components or the second and first biologically active components may be identical as long as the remaining component is capable of reacting with both of the others. All three biologically active components may be antigens and antibodies. The carrier is suitably made of plastic material.

Abstract: The system is formed by station nodes connected to one another via transmissions at each end of which is a special voltage adjustment unit of the converter type which adjusts the transmission voltage to that of the station. The adjustment unit in each case has an inbuilt switch function of the thyristor type. The system provides a mains structure with independent station nodes and transmissions. Each individual transmission can be connected for an optimal voltage level, and given an individual adjustment which from a voltage viewpoint does not affect the other transmissions in the system.
