Disclosed are solar cells employing slightly curved or nearly flat monocrystalline silicon ribbons. The ribbons are formed by cutting or slicing monocrystalline hollow tubes along their lengths, the tubes having been formed according to crystal growing processes disclosed in U.S. Pat. No. 3,591,348.

An extended surface area electrode for an electrochemical cell is provided by causing a bed of conducting particles to be expanded in the form of a fluidized bed by controlled upward flow of electrolyte through an electrode chamber containing current-carrying conducting means which makes contact with the fluidized bed.

There is disclosed a bipolar electrolytic cell comprising a row of spaced-apart electrodes which include at least one bipolar intermediate electrode. There are an inlet for the supply of electrolyte liquid and an outlet for the discharge of treated liquid, the cell being such that liquid can flow from the inlet to the outlet via a path in which it passes in succession through all the spaces between the electrodes in the row, in each case across the faces of the two electrodes on opposite sides o...

Electrochemical cells having a first central anode, a second anode in the form of a concentric annular ring disposed around the central anode, a cathode, also in the form of a concentric annular ring, positioned between the first and second anodes, but not in mechanical contact therewith, and an electrolytic solution between and in contact with the anodes and cathode. The central anode can be in the form of a cylindrical rod or, preferably, a concentric annular ring.

Method of treating virus disorders by administering 1,2-diphenyl-.alpha.,.beta.-diketone into the blood. Entry of this compound into the sick cells results in, because of the pH and redox-potential conditions in those cells, oxidation phenomena and deposition of an antiseptic substance in the sick cells, thereby causing cellular aging and necrosis.

In an electric cell having a solid electrolyte which bounds on one side a mpartment for liquid anode and on its opposite side a compartment for liquid cathode, the liquid anode compartment is made of very limited capacity. The bulk of the liquid anode required by the cell is held in a reservoir and fed to the liquid anode compartment by a capillary duct to provide a restricted feed which limits the flow of liquid anode therebetween. The reservoir may be disposed within the cell, or outside the c...

A method of making low cost photovoltaic cells on a large scale basis by means of a continuous process of coating sheet glass while the sheet glass moves in and has its under surface immersed in a tank of molten material, comprising forming the film of CdS microcrystals on the glass sheet, which has previously been coated with transparent SnO.sub.x to a thickness of about 0.3 to 0.6 microns. A water solution of a cadmium salt, a sulphur compound, and an aluminum containing soluble compound is in...

Transistor memory cells which may be operated in both the erasable "read only" and the "random access" modes. Each cell includes a plurality of MOS transistors interconnected to permit random access storage and at least two MNOS transistors. The latter may be set, one to one threshold level and the other to a second threshold level to represent read only storage of a logic 1, and the threshold levels may be reversed to represent read only storage of a logic 0. The MOS transistors may be randomly...

The invention relates to electrochemical cells whereof one electrode is of a particulate type which may comprise a fluidized bed electrode, a packed bed electrode or a circulating bed electrode, an electrolyte being passed through the particulate electrode possibly for fluidizing and/or circulating the particles of the electrode. Whereas in previous cells of this kind a diaphragm has been arranged between the particulate electrode and the counterelectrode of the cell, it has been discovered that...

Method of treating virus disorders by administering certain compounds, such as benzoyl peroxide, into the blood. Entry of these compounds into the sick cells results in, because of the pH and redox-potential conditions in those cells, oxidation phenomena and deposition of an antiseptic substance in the sick cells, thereby causing cellular aging and necrosis.
