Abstract: ABSTRACT         A regulated substrate bias voltage generating system for maintaining a minimum data retaining current through an associated MOS memory.  The negative sub-strate bias voltage is generated by a charge pump operating under the control of a two-phased output oscillator, the operation of which is enabled and disabled by the output signals from a MOS memory over-current sensor, a MOS memory under-current sensor, and a bias voltage level sensor.

Abstract: RECOVERY OF CHLORINE VALUES IN INTEGRATED PROCESS FOR OXYCHLO-RINATION AND COMBUSTION OF CHLO-RINATED HYDROCARBONS.          Abstract of the Disclosure In an integrated process for oxychlorination and combustion of chlorinated hydrocarbons, chlorinated hydro-carbons is burned to recover chlorine values essentially as hydrogen chloride.  Combustion effluent and off-gas from an oxychlorination reaction are simultaneously treated to recover anhydrous hydrogen chloride for use in the oxychlorination reaction.  In accordance with one embodiment, off-gas from the oxychlorination is employed in the combustion, prior to hydrogen chloride recovery in order to utilize any oxygen values therein.  The process has particular applicability to an oxychlorination reaction of the type wherein a molten salt containing the higher and lower valent chlorides of a multi-valent metal is contacted with hydrogen chloride and oxygen to recover hydrogen chloride by enriching the higher valent metal chloride content of the molten salt.

Abstract: APPLICATION OF INDICIA TO ARTICLES                   ABSTRACT OF THE DISCLOSURE     A compact and inexpensive decorator for transferring labels by heat and pressure from a carrier strip to articles such as bottles.  The decorator is designed as a unit, including infeed and outfeed conveyors, a turret for holding articles during label-ling and maintaining their shape by inflation, a deck bearing a transport for the carrier web and a device for impressing labels from the strip onto the articles, and a control module.  For round articles the turret includes interchangeable Index and Decorator cups, while for oval articles an easily removed turret base with article cutouts is used.  The deck may be adjusted in its height and angular orientation with respect to the turret to permit deco-ration of a wide variety of article faces.  The carrier web trans-port includes a capstan web drive for pulling the web, a double gate, and a dancer roll, which provide label-by-label advance of the web controlled by signals from a photoelectric web monitor and a container detector.  The double gate and dancer roll are included to avoid regions of slack or high tension in the web during inter-mittent advance.

Abstract: Abstract A process for economically converting carbo-metallic oils to lighter products.  The carbo-metallic oils contain 650°F plus material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalent of heavy metals content of at least about 4 parts per million.          This process comprises flowing the carbo-metallic oil to-gether with particulate cracking catalyst through a progres-sive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a pre-determined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400°F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.  The spent, coke-laden catalyst is separated from the stream of hydrocarbons formed by vaporized feed and re-sultant cracking products and regenerated in one or more regeneration beds in one or more regeneration zones by burn-ing the coke on the spent catalyst with oxygen.  The re-generated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil.  A portion of the catalyst is withdrawn from the cycle, passed through a magnetic field to separate the mass of catalyst into high activity catalyst and low activity catalyst, returning the high activity catalyst the cycle and disposing of the low activity catalyst.

Abstract: ABSTRACT      A system for quickly stopping the internal combus-tion engine of a powered implement having a deadman control normally biased toward a first position and actuable by the implement operator to a second position for normal implement operation and optionally to a third position for actuating an engine starting mechanism is disclosed.  The engine has a flywheel coupled thereto for rotation with the engine crankshaft and that flywheel is provided with an annular friction surface of generally cylindrical configuration disposed coaxial with the axis of rotation of the flywheel.  A braking member having a second friction surface is normally biased into engagement with the flywheel friction surface and coupled to a deadman control so that the two friction surfaces will be disengaged upon movement of the deadman control to a second or operational position by the implement operator.  An arrangement for disabling the engine ignition system upon release of the deadman control and prior to engagement of the friction surfaces is disclosed.  The brake is self-actuating in the sense that once the friction surfaces are engaged, continued flywheel rotation forces or wedges the two braking surfaces together with substantially greater force than the force causing initial contact between those two surfaces.

Water or another suitable rinse liquid is distributed over the operative surfaces of the collector electrodes by a liquid distribution arrangement comprising several tubular distributor members (60), each member includ-ing uniformly spaced, tubular overflow nozzles (62 and 63) that project vertically upwardly and that are individually adjustable to provide for uniform flow.  The end overflow nozzles (63) that are adjacent the respective inlets (64) have closed lower ends.  Each end nozzle further has a circular inlet aperture or bore (94) in its tubular wall, and each is oriented so that the aperture generally faces toward the associated distributor member inlet.  The construction and orientation of the end nozzles assures adequate flow from the turbulent flow region of the dis-tributor members, thereby avoiding dry spots and the resultant sparking that tends to occur at any dry spot.

For example, if the solvent were not pre-sent in the activator solution in proportions of at least 1 wt.%, the activator solution would not be homogenous.
