A cell comprising one or more stands in which crop containers are arranged in a plurality of layers one above the other and light sources are arranged between the containers, whereby between a light source (or light sources) and a container located above said light source(s) there is arranged a plate of insulating material, at least the side of the plate facing light source(s) being reflecting.

A cell is provided in which a flat plate portion of a collector portion is prevented from making contact with a positive or negative electrode in a power generating element to cause a short circuit, the application area of a material can be widened, and edge portions of an electrode plate can be surely connected and fixed to a collector. In a collector portion of a negative or positive collector, press holds of a gap (groove) which opens on the side of a basal portion are formed by bending back ...

A patient population of cells in a tissue sample is treated with a solution containing radioactive gallium to allow the gallium to be absorbed by the cells. The cells are examined to determine amounts of radioactive material absorbed by the cells by passage of the solution through a cell counter and scintillation counter. Outputs of the counters are correlated to produce signals indicative of the gallium absorption of each cell. The amount of gallium absorption by a cell is a function of maligna...

There is disclosed a novel cell separator made of a grafted membrane comprising a polyethylene film which is graft-copolymerized with a monomer having an ion exchange group, characterized in that said membrane has an area which is not grafted at all or an area of low degree grafting. By making use of this membrane, a small size and thin cell having excellent performance as well as satisfactory mechanical strength can be produced at low cost with great advantages.

A point contact solar cell structure and method of manufacturing which provides metal contact from positive and negative bus bars to alternating n-wells and p-wells in a solar cell crystal. The solar cell spans two side-by-side metal bus bars. On the bottom surface of the cell crystal two side-by-side perforated metal layers contact wells of only one conductivity type. Holes in the perforated metal layers are located beneath wells of the opposite conductivity type. An insulated junction between ...

A galvanic cell is disclosed comprising spaced cathodic and anodic electrodes and an electrolyte having an organic aprotic solvent and a soluble solute such as a Lewis acid. At least one of the electrodes has a conductive support member comprising a metal selected from the group consisting of aluminum, magnesium and beryllium.

A unitary cell assembly comprises a plurality of regular, six sided, rectilinear and contiguous hollow cells, each cell having an opening at each vertex thereof, the openings of adjacent cells being adjacent thus providing intercommunication between adjacent cells for the passage of a fluid therebetween. In a preferred form, the cells are cubic. The cell walls are preferably disposed at an angle with respect to the horizontal and verticle for several uses. For example, for use as an oyster cultc...

A load cell consisting basically of three structural regions concentrically arranged, a central or hub region adapted to receive loading from a first direction, an outer tubular region adapted to receive opposite and equal loading and a web or diaphragm region interconnecting the central and outer regions, and wherein strain gauges are placed on the surface of the web region and respond to bending strain produced in the web region by load so applied.

A fluid-filled amplifier cell for laser generation comprises an elongated housing wherein at least one end contains, within the cell, a window supported at the Brewster angle and wherein such end is plugged with a mirror.

An improvement in the operation of chlorate cells is described in which the product liquor flow from one or a plurality of electrolytic alkali metal chlorate cells is fed to a collection zone provided with a baffling arrangement such that hydrogen gas disengaging from the cell liquor does so under a liquid seal that separates it from the gases in the cell liquor outlet. The liquid seal for disengaging hydrogen from the liquor insures that there is no direct communication between the gases being ...
