Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to an X-ray inspection system for security screening applications of the type which are employed at aircraft terminals to determine if dangerous items are being carried in passenger luggage.  The system in accordance with the invention includes a detector station having a linear array of phototransistors, covered with a fluorescent screen, disposed on one side of the conveyor belt which carries the luggage past the detector station.  On the other side of the belt, and disposed in parallel arrangement with the array, is an X-ray head, and objects passing between the array and the source will alter the density of the rays emitted by the source so that an X-ray picture can be obtained, as well known in the art.  The inventive system uses such an array to eliminate the requirement for optical systems of present screen-ing apparatus.  The disclosure also teaches a mode for operating the array which eliminates difficulties due to wide ranging differences in the characteristics of the individual photo-transistors, and it also teaches a mode of operating each of the phototransistors to increase the outputs thereof.

Abstract: EDGE CONTROL FOR CALENDER COVERING INDUSTRIAL BELTING    Abstract of the Invention An apparatus for squaring or trimming the edges of the elastomeric (uncured) cover of an industrial belt. An edge sensor is disposed to track each of the edges of a bare or uncovered carcass forward of the calender nip in which the cover is applied. Rotating trim blades for trimming excess gum from the respective edges of the covered belt are moved laterally proportionally to the algebraic sum of the deviations of the edges of the carcass from their respective ideal lines. Thus, an adequate but not excessive amount of the cover gum is provided to cover the respective edges of the carcass of the belt.  The respective edge sensors are hydraulically connected with the trim blades for synchronized movement so as to maintain the described thickness of cover gum outwardly from the edges of the carcass.  me foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed descrip-tion.

Abstract: ATTACHABLE HANGER FOR CONTAINERS                 Inventor: David A. Winchell ABSTRACT OF THE DISCLOSURE     A one-piece hanger for a container comprises attachment means to a container and an  elongated, flexible hanger member secured at both ends to the attaching means to define a closed loop.  The elongated hanger member is positioned in generally longitudinal relationship to the attaching means and defines a pair of first flex sections positioned respectively adjacent the ends of the hanger mem-bers, and a pair of spaced second flex sections, positioned more remotely from the ends of the flexible hanger member.

Abstract: WASTEWATER FLOTATION Abstract of the Disclosure:        A flow of wastewater is adjusted to near zero streaming potential by injecting a combination of a mineral acid and a multivalent metal coagulant into the wastewater. The potential is measured in streaming detector units.  The thus adjusted flow enters a coagulation cell for contacting the flow with dense quantities of small bubbles to form an initial floc.  The flow then passes to a basin where a combined floc is separated and skimmed along the surface of the basin to a location generally above the entrance to the basin.  A supplemental supply of bubbles preferably is maintained below the surface of the skimmings at this location in order to decrease the water content of the skimmings.

Abstract: ABSTRACT      A method and apparatus for developing an electrographic-latent image on a pre-treated paper medium, by utilizing multiple rollers partially dipped in a liquid carrier.      A pre-treated paper medium comprised of a conductively treated paper base supporting a plastic dielectric coating on each of its sides, is positioned of a plurality of styli-which receive variable information in the form of electronic signals from a data processor, or other equipment and by selectively changing the plurality of styli generating a latent electrographic image of alphanumeric characters or paper which is retained by the coating.      The latent image is developed, i.e. made visible, by subjecting the paper medium to charged toning particles sus-pended in a liquid toning carrier.  Multiple rollers, one each at predetermined locations, are partially submerged in a liquid toning carrier and pick up sufficient toning so as to form a meniscus between the upper portions of each roller and the paper medium.  The image is then fixed i.e. made permanent by vaporizing the liquid carrier with heat.

Abstract: ABSTRACT OF THE INVENTION A method for sequential treatment of formation strata when treating fluid is pumped into a well at a matrix rate by temporarily closing perfora-tions in the well casing.  The perforations are closed by ball sealers injected into the well during the treatment.  The ball sealers are sized to plug the perforations and have a density less than the density of the treating fluid. The treating fluid is injected at a rate which transports the ball sealers to the perforations but which is sufficiently low to prevent formation fracture.
