Abstract: A combined fuel vapor injector and igniter system for internal combustion engines and method of operating the engine therewith in which liquid fuel enters an injector-igniter device, is vaporized using the engine''s heat of combustion, and exits in vapor form into the engine combustion chamber where it mixes with air or an air-fuel mixture which has entered through an intake valve, or port, and the resulting air-fuel mixture is ignited. The system assures reliable ignition, so that engines may be run at leaner than stoichiometric air-fuel ratios to take advantage of increased fuel economy, and reduced emissions of the oxides of nitrogen, hydrocarbons and carbon monoxide. Power output equalization is attained between cylinders.

Abstract: Method and apparatus for scrambling and unscrambling television video and audio signals in a subscription television system in which program selections of subscribers are known at a central transmitting site, and control signals encoded into vertical blanking intervals of the video signals are addressed to receivers authorized to receive unscrambled transmissions, to selectively control unscrambling at those receivers. In an unscrambler at each subscriber''s receiver, the control signals are decoded, and, if addressed to the particular subscriber''s receiver, operate to enable or disable the unscrambler, or to frequently vary its mode of operation, thereby greatly increasing the security of the system and deterring viewing of scrambled transmissions. Video scrambling and unscrambling are effected by inversion of selected horizontal lines of a transmitted television picture, and possible modes of scrambling and unscrambling include inversion of alternate groups of equal numbers of lines, inversion or non-inversion selected on a lineby-line basis, with an appropriate control signal being transmitted with each line, and inversion or non-inversion in a preselected sequence, as determined by synchronized logic at the receivers and the transmitting site.

Abstract: The optical stabilization of the paired ocular paths of a binocular against accidental angular motion is disclosed. Each ocular path of the disclosed binocular includes an objective, an eye piece, and a mirror array for relaying the optical path to the viewer. The mirror arrays for each ocular path are arranged to impinge on opposite sides of a movable and stabilizing back to back reflective element. The movable back to back reflective element is pivoted about at least one axis substantially normal to the viewing axis of the binocular. Movement of the back to back reflective element provides precisely equal stabilization of each of the light paths. A first mirror array is disclosed wherein a periscope for one light path and a corner cube for the opposite light path each impinge their light on opposite sides of a fluid cell mounted mirror. A second mirror array is disclosed wherein side-by-side mirror arrangements similar in effect to Porro prisms for each ocular path have corresponding stabilizer mirror pairs mounted for identical stabilizing movement.

Abstract: A method is described for recovering metal and sulfate values from electrolyte solutions which are withdrawn from the in-place electrolysis of sulfide ore bodies positioned beneath the earth''s surface. The electrolysis of such ore bodies produces finely divided metals, metal ions and sulfate ions. The particular metal ions present in the electrolyte is dependent upon the type of sulfide ore body being electrolyzed and the conditions of the electrolysis. The present process provides a means for continuously or periodically withdrawing electrolyte and finely divided metals from the electrolysis, separating the metal values both as solids and as ions in solution, recovering the useful products therefrom, readjusting the electrolyte to the desired conditions of pH and ion concentration and returning the readjusted electrolyte to the electrolysis.

Abstract: An apparatus for blow molding hollow, plastic articles to provide a finished base in the molding step is disclosed. A plastic parison is received between separable mold halves, each mold half having a top mold component and a bottom mold component. The bottom mold component is additionally movable along the center axis of the article. Also provided is a tailgripping assembly which is also movable along the center axis of the article and which grips the tail of the parison when the mold halves are in the closed position. The tail-gripping assembly is connected to a power source to provide such axial movement. Engaging means are provided for the tail-gripping means to engage the bottom mold component during movement of the former to impart movement to the latter while the mold halves are in a closed position. When the mold halves are closed the tail-gripping assembly grips the tail of the parison and then moves downwardly to separate the tail from the article and to also engage the bottom mold component. The engaged bottom mold components are pulled away from the article. Upon opening of the mold halves the tailless article is free to fall from the mold as the bottom mold component has been pulled away from the article thus removing bottom support therefor.
