Abstract: Apparatus and methods for coating particulates to suppress dust and/or modify the behavior of the particulate, spray the coating onto the particulate as it moves along inclined surfaces within the coater apparatus. The coating is sprayed generally as a mist and the particulates remain free-flowing throughout the apparatus and when discharged therefrom. Apparatus using a single spray step and subsequent transfer coating steps to effect particulate-to-particulate transfer of coating achieve at least about 75% coating of the particulate. Embodiments of the apparatus with dual spray steps and without the subsequent transfer coating steps are capable of achieving at least 85% coating of particulates with a single pass through the apparatus.

Abstract: The invention concerns a kit for preventing or treating oxidative stress in humans or animals by means of therapeutically active hydrogen molecules. The hydrogen molecules are formed by reacting a base metal with aqueous acids or bases and by reacting a saline hydride with water or aqueous acids.

Abstract: A pump for pumping fluid down a well bore in a rock formation comprises: intake and discharge passages; a pumping chamber with a plunger therein; intake and discharge valve assemblies in the intake passage and the discharge passages. At least one valve assembly has a valve body movable into sealing contact with the valve seat by fluid pressure in the pumping chamber. The valve seat may have a cylindrical outer surface for mating reception in said intake passage, and a shoulder with a radially-projecting surface biased against a wall for sealing. A cushioning member may be interposed between the valve body and the valve seat. A seal may be interposed between said valve body and said valve seat, and configured so that between 35% and 60% of a sealing surface of said valve seat contacts the valve body.

Abstract: Described are methods for electrical treatment of biological cells, in particular using electrical field pulses, involving the steps: arrangement of the cells (1) on apertures (2) of a solid planar carrier element (3) which divides a measuring chamber (10) into two compartments (11, 12); and temporary formation of an electrical treatment field which permeates the cells, wherein an alternating-current impedance measurement takes place on the carrier element (3), and from the result of the alternating-current impedance measurement, a degree of coverage of the carrier element and/or healing of the cells after electrical treatment are/is acquired. Also described are devices for implementing the methods.

Abstract: A chamber for treating cells contained in a suspension in an electric field, the chamber having a vessel for holding the suspension and at least two electrodes with electrode surfaces that face each other. The suspension may be placed between the electrode surfaces and the electrodes are connectable to different poles of a source of voltage to generate an electric field between the electrode surfaces. The electrodes are laminate and continuous and are configured to generate a non-uniform field. Moreover, the electrodes have electrode surfaces made of electrically conductive material, wherein the electrode surface of at least one of the two electrodes is shaped such that a non-uniform field with several maxima distributed over the electrode surface may be generated between the two electrodes.

Abstract: A method of modifying antigen-presenting cells is described, in which antigens of diseased cells or their cell components are transferred to the antigen-presenting cells, the antigen-presenting cells being brought into contact with the diseased cells or their cell components on a solid-phase substrate or in a suspension through introduction into a shared suspension and exertion of external forces, membrane components having antigens without cell nuclei of the diseased cells or their cell components being transferred to the antigen-presenting cells and subsequently a separation of the modified cells from the solid-phase substrate or from the suspension being performed.
