C-7638 MEMBRANE-ELECTRODE PACK ALKALI CHLORINE CELL A novel commercial chlor-alkali electrolytic cell which has a pack of less than about 25 interleaved parallel planar electrode frames and substantially horizontal conductor rods. The pack is at least half and preferably twice as tall as it is thick.

An electrical storage cell of the reduction oxidation (REDOX) type is divided into anode and cathode compartments by a membrane, each compartment having a circulating fluid containing an ion couple for producing an electric potential at respective solid inert electrodes disposed therein. The anode electrode is plated with one layer of copper, silver or gold and another layer of lead or cadmium. Th...

There is disclosed a method of using an exhaust gas catalyst for treatment of exhaust gases developed by burning a hydrocarbon based fuel in an internal combustion engine. These exhaust gases contain varying amounts of unburned hydrocarbons, carbon monoxide and oxides of nitrogen depending upon the operating conditions of the internal combustion engine. This specification teaches use of an improve...

A vacuum circuit interrupter including axial magnetic field generating means, and arc contact structure comprising means for spacially modulating the axial magnetic field over the area of the contact. This contact structure produces adjacent regions of different magnetic field strength over the contact area, whereby a plurality of spaced apart low arc voltage, stable parallel arc current paths are...

The roots of human hairs of a patient are devitalized using high intensity, short duration pulses of light having wavelengths with respect to which the skin of the patient is non-absorbative and the hair of the patient is relatively absorbative. A narrow, focused beam of the light is aimed at the epidermis of the patient adjacent the hair such that an extension of the beam intersects the hair root...
