Abstract: Halogen is produced by electrolyzing an aqueous halide in a specially designed cell. The cell comprises an analyte chamber and a catholyte chamber separated by a permeable membrane or diaphragm, notably an ion exchange (generally cation exchange) polymer. At least one electrode comprises at least two sections. One section comprises a gas and electrolyte permeable layer, sheet or mat having a catalytic surtace, i.e. one having a low overvoltage, (low hydrogen overvoltage if the cathode and low halogen overvoltage if the anode). This layer is spaced from themembrane by a second portion comprising an electroconductive resiliently compressible layer or mat, which is in contact with the membrane on one side thereof, the other side thereof being in contact with the main cathode. This second or spacer section advantageously has an electrode surface having a higher overvoltage than the first electrode surface. Preferably the cathode has the above construction. Upon electrolysis of alkali metal chloride or other halide in such a cell and with a cathode of the type described above, a low voltage is obtained even at high current densities and the cathode efficiency is high.

Granted: 1990-04-12
Abstract: The production of tension-proof, liquid impermeable, flexible bands which are preferably utilized for presses to dewater fiber material webs and are subjected therein to substantial tensile stresses between a press-shoe and a press-roll as the same glide across the press-shoe which is effected by means of penetration of a flowable mixture of a prepolymer with a cross linking agent onto the reinforcing band, preferably formed of fabric and receiving the tension forces in a direction longitudinally of the press band. Penetration most effectively occurs through covering the fabric band by pouring thereover of the flowable mixture as the band is in stretched condition and is moved.
Patent DE-3486463-D1 (DE)
Inventor: EASTMAN JAY M
IPC: G06K7/00
Filed: 1984-08-17
Granted: 1998-02-05
Abstract: An optical device for detecting bar codes (markings or patterns which symbolize data such as the name and vendor of a product) are detected by an optical device which serves as a bar code scanner. A laser diode and associated optics provides an invisible beam. A visible marker beam coincident with the laser beam is generated by a lamp and associated optics and directed coaxial with the laser beam so as to enable the laser beam to be scanned across the bar code by moving a housing in which the laser and the lamp and their associated optics are disposed. Also contained in the housing is a photodetector on which scattered light from the code is incident after passing through a collection lens located at an outlet port for the beams. An aperture is positioned between the collection lens and the detector. The location and size of the aperture and the focal length of the lens are related such that the illumination by the reflected light of the detector is substantially constant and the output signal from the detector which represents the bar code is also constant amplitude over a wide depth of focus in front of the beam port. Unwanted reflections (gloss over the bar code) are rejected by selecting the polarization of the reflections opposite to the polarization of the laser beam, as by the use of a polarizing beam splitter. A spectral beam splitter is used near the detector to select the scattered laser light for the photodetector which generates electrical signals corresponding to the bar code.
