Abstract: ABSTRACT        Strip film of the conventional silver halide emulsion type is duplicated by optionally projecting the images onto a high speed electrophotographic film in a system comprising a flow type camera having the original film and the electrophotographic film traveling at the identical film speed. The first station for the electrophotographic film is a charging station, followed by the projection slit, a toning station and a toner fixing station.      The background density of the original film is measured by photometric means and compared with preset density standards, the resulting information being used to enhance the images produced on the electrophotographic film by varying the charge voltage level. Charge level will control the amount of toner which adheres for a given time of toning.

Abstract: Abstract A new part length rod is provided which may be used to not only control xenon induced power oscillations but also to contribute to shutdown reactivity when a rapid shutdown of the reactor is required.          The part length rod consists of a control rod with three regions.          The lower control region is a longer weaker active portion separated from an upper stronger shorter poison section by an intermetiate section which is a relative non-absorber of neutrons.  The combination of the longer weaker control section with the upper high worth poison section permits the part length rod of this invention to be scrammed into the core.  When a reactor shutdown is required but also permits the control rod to be used as a tool to control power distribution in both the axial and radial directions during normal operation.

Abstract: A FLOATING SKIMMER FOR CLEANING THE SURFACE OF A BODY OF LIQUID            Abstract of the Disclosure A floating skimmer, for cleaning the surface of the liquid around the skimmer, has an outer, annular shaped body with an inner cavity.  Flotation and ballast chambers in the outer body regulate the level of flotation of the weir, and a peripheral opening admits a flow of liquid into the central cavity.  The liquid is pumped out of the central cavity through a drain opening in the base plate.  A movable weir extends across the width of the inlet opening and regulates the quantity and velocity of liquid which flows through the opening and into the central cavity.  The outer edge of the weir is connected to the body by a hinge connection which permits the weir to articulate about that edge.  A float is mounted beneath the weir so that the weir floats on the liquid within the central cavity and with the back inner edge of the weir elevated.  This produces a cascade of liquid off the upper edge of the weir and a regulated skimming of the surface of the liquid by the cascade action.

A low-level pull-in comparator compares a signal proportional to armature current to a low-level reference potential and causes the field to be shunted when the armature current signal falls below the low-level reference potential. A high-level drop-out comparator compares a signal proportional to armature current to a second independent high-level reference potential and causes the full field to be applied when the armature current signal is greater than the high-level reference potential.  Prior to actuation, the pull-in compa-rator disables the drop-out comparator.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention involves a method of making a gas-impervious container for the hot isostatic compaction of particulate material into an article of intricate config-uration.  It comprises providing a removable pattern in the appropriate precompaction configuration of the article to be produced, forming a shell of vitreous frit on the pattern, heating the shell to effect vitrification thereof, and coating the vitreous shell with a layer of metallic material to form a gas-impervious metallic shell around the vitreous shell.  The pattern may be removed at any time after formation of the shell of vitreous frit.  The gas-impervious container thus produced is well-suited for use in hot isostatic compaction processes wherein dense articles of complex shape, such as gas turbine engine components, are produced from superalloy powders.
