Abstract: ABSTRACT OF THE DISCLOSURE A cathode assembly for a plural cell electrolyzer is provided which comprises a rigid cathode support joined to a cathode by a first set of connecting members and to an anode in an adjacent cell by a second set of connecting members.  The cathode support and first set of connectors enable the cathode to maintain an essentially flat surface. The support and second set of connectors stabilize the cell frame and enable the anode likewise to maintain a flat sur-face.  Thus, the electrodes in a cell may be set accurately flat and parallel to minimize the interelectrode gap and the cell voltage drop due to the electrolyte path, and, con-sequently, to improve cell efficiency.

Abstract: 27-11-1979                 l                     PHN 9350 Abstract. "high-voltage generating device"     A high-voltage generating device which compri-ses a transformer whose secondary coil is subdivided into sections which are series-connected via diodes.           The beginning of the first section is connected to a point of fixed potential via a further diode. The beginning and the end of the first section are also con-nected to this point via capacitors. As a result, the voltage on a tapping lead which is connected, for example before the second section, has a value which amounts to from one to two times the voltage difference across a section, as desired.

Abstract: PROCESS AND APPARATUS FOR ENAMELLING THE INSIDE SURFACE  OF HOLLOW VESSELS     Abstract of the Disclosure A process of enameling the inside surface of hollow vessels, which have two openings at opposite points. In a hot-water reservoir to be enameled these openings are provided at both ends. One opening is connected to a vacuum pump and the other to a conduit which incorporates a valve and leads to an enamel slip reservoir. In a first step, a vacuum pump is operated to pre-evacuate the interior of the hollow vessel so that air is removed from the pores at the inside surface of the hollow vessel. In this step the valve in the slip conduit remains closed. When the vessel has been pre-evacuated to about 40 to 80 torrs absolute, the valve is opened so that slip flows suddenly into the hollow vessel and fills the pores while the evacuation is continued and slip is sucked into the hollow vessel until the slip emerges from the opening through which the hollow vessel is being evacuated.

Abstract: WAVEFORM DIGITIZER                       Abstract of the Disclosure A waveform digitizer particularly suitable for use in electronic test systems for analyzing and displaying analog signals is disclosed.   A digitally derived reference voltage is compared with the analog signal to be digitized during a series of comparison sequences. Simultaneously with the start of each comparison sequence a digital clock is started. Each time the analog signal rises above, or drops below, the reference voltage a decision change detector producesan enable pulse. Each time an enable pulse occurs, a data word, having a portionrelated to the value of the digitally derived reference voltage and a portion related to the digital clock value, is stored and/or used to control a display. At the end of the first comparison sequence (determined when the digital clock value reaches a predetermined level) the reference voltage is incremented and a second comparison sequence started These steps are repeated until the reference voltage reaches a predetermined level. The resulting set of digital words is a digitized equivalent of the waveform of the analog signal.

Abstract: ABSTRACT OF THE DISCLOSURE         In a process for producing sebacic acid from adipic acid comprising three steps, i.e. (1) half-esterification of adipic acid with methanol to yield monomethyl adipate, (2) electrolytic condensation of the monomethyl adipate to yield dimethyl sebacate, followed by separation and purification of the dimethyl sebacate and (3) hydrolysis of dimethyl sebacate to yield sebacic acid, the desired sebacic acid can be produced with easy recovery of an alkali metal salt of monomethyl adipate and easy separation of the dimethyl sebacate by removing the methanol from the electrolytic solution containing dimethyl sebacate after the electrolytic condensation after or at the same time that water is added to the electrolytic solution, separating the residual solution into oily and aqueous layers, obtaining dimethyl sebacate from the oil layer, recovering the alkali metal salt of monomethyl adipate as a monomethyl adipate solution from the aqueous layer with addition of monomethyl adipate to the aqueous layer before or after removal of water by evaporation from the aqueous layer, and recycling the monomethyl adipate solution to the electrolytic condensation step.

Abstract: Case No: 4843 ABSTRACT OF THE DISCLOSURE      This invention relates to an improved method of preparing a zeolite composition in which some or all of the cations have been exchanged for gallium ions.  The zeolite has a high silica to alumina ratio and is prepared by crystallisation from an aqueous solution containing a mixture of a source of silica, a source of alumina, and at least two other components selected from the group of alkali metal ions, ammonia and an organic nitrogen containing base.  The improvement lies in washing the crystallised zeolite with acidified and/or deionised water, calcining the washed product at an elevated temperature, contacting the calcined product with an acid, refluxing the acid treated zeolite with a solution of a gallium compound to produce a gallium exchange zeolite and washing the gallium exchanged zeolite with water to render it substantially free from any impregnated gallium or gallium compound.  The zeolite composition is useful as a catalyst for hydrocarbon conversion reactions.
