Abstract: ABSTRACT         The present invention relates to an improved container construction including a molded resilient plastic vessel having one open end and a molded resilient plastic cover removably and sealingly mountable on the open end of the vessel for containing materials, including liquids, in the vessel.  The molded resilient plastic vessel includes a right circular cylindrical wall having a bottom formed integral with the interior of the wall adjacent to one end leaving the opposite end of the wall open.  A handle assembly is formed integral with the ex-terior of the cylindrical wall adjacent to the open end. The handle assembly includes an arcuate handle having opposite ends formed integral with the cylindrical wall. The vessel includes a top seal defining the open end. The top seal includes a bead formed integral with the outer surface of the cylindrical wall and a top surface defining the open end of the vessel.  The bead has a side and a lower locking face.  The lower locking face is on the bead adjacent to the bottom.  The cover includes a substantially flat circular top having a cover seal formed integral with the outer periphery of the top.  The cover seal includes a ring wall formed integral with the outer periphery of the top.  An annular inner seal is formed integral with the top for engagement with the vessel.  An annular wall seal is formed integral with the interior surface of the ring wall and is sealingly engageable with the side of the bead of the top seal of the vessel.  The cover seal includes an annular bead formed integral with the lower locking face of the vessel top seal for holding the cover onto the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE    A blind riveting and sealing system for sealing circular openings in sheet type materials and for securing together plural sheets.  Each of the sheets to be secured together has an iden-tical size hole for accomodating the rivet of the invention in a force fit relationship.  Additionally, one of the sheets has a reduced diameter step in the rivet receiving hole to form a resi-lient annular locking flange.  The rivet of the invention has a necked down portion to form a beveled seat face.  This beveled seat face engages the resilient annular locking flange to lock the rivet in position and seal the circular openings in the sheets.

Abstract: ABSTRACT OF THE DISCLOSURE         A convertible aircraft engine, capable of turboshaft and/or turbofan modes of operation, is provided in a con-figuration that combines certain components to permit variation in bypass flow to match engine airflows with the mode of the engine operation. The provided components permit the engine to decrease the power requirements of the engine's forward fan when the engine is operated in the turboshaft mode. To permit a decrease in fan power requirements, the fan is split into an outer portion and an inner portion separated by a rotating shroud. Airflow into the fan's outer portion is controlled with a part span inlet  guide vane and an outlet guide vane. The guide vanes can be used to lessen the load on the outer portion of the fan while the inner portion continues to accelerate and compress a normal airflow into an engine compressor for supplying the engine's core. The power normally used to drive the fan outer portion is ued instead to power a transfer shaft in the turboshaft mode.

Abstract: METHOD FOR ELIMINATING MOTION INDUCED       FLICKER IN A VIDEO IMAGE                     ABSTRACT            In an image processing system, a method is shown for efficiently transmitting data representing picture information in fields subsequent to a first field and for suppressing motion induced flicker in the processed image.  Using previously processed first field data which is used to predict values for picture elements in subsequent fields, a gradient value is calculated which indicates relative picture activity.  A difference value for the picture elements in the subsequent fields is calculated and is limited in magnitude by the gradient value for each picture element. The limited difference value is encoded as a function of previous difference value and transmitted to a remote location for decoding and picture reconstruction and display.

Abstract: ABSTRACT OF THE DISCLOSURE In a high-speed, high-volume ventilation fan, a noise-attenuating housing structure includes a perforated inner casing contained within a solid-walled outer casing. Filling the space between the inner and outer casings is a porous, sound-absorbing material.  To prevent loss of downstream pressure, and therefore operational efficiency, due to leakages of air through the sound-absorbing material from the downstream side at the fan blades to the upstream side thereof, an annular anti-flow barrier is situated in the space between the inner and outer casings slightly down-stream of the fan blades.  The structure thus provides a high degree of noise attenuation without sacrificing opera-tional efficiency.

Abstract: PHD. 82.072             10 ABSTRACT:     Magneto-optical storage elements (light switch-ing elements) are formed on a carrier body (substrate) of comparatively small dimensions.  In accordance with the relevant application, different configurations of light switching elements can be cut from the substrate. In order to form a magneto-optical printer, the light switching elements LZ on the substrate T are combined so as to form groups M which are separated from one another by an equidistant space a.  Each group M is associated with a self-focusing lens LS so that the distances between all image points of a plurality of groups M on the record carrier Z are equal.  A magneto-optical line printer can be obtained by arranging several light switching masks S, each of which comprises several groups M, together with the necessary self-focusing lenses LS, in adjacent positions.

Abstract: ABSTRACT            There is described a method of and apparatus for monitoring the concentration of gas in a liquid.  The apparatus includes a semi-permeable diaphragm across the face of which the liquid flows.  Gas contained in the Liquid permeates through the diaphragm into a chamber and the pressure within the chamber is measured.  This pressure is representative of the concentration of gas in the liquid and permits control of the quantity of gas injected.  In particular there is described a method and apparatus for monitoring the concentration of two different gases which may be dissolved in a flowing liquid.

Abstract: Abstract of the Disclosure A connector as disclosed for connecting fluid passages through a flexible sheet material.  The connector is appropriate for use in connecting the coolant lines of a personal cooling garment through a waterproof immersion suit or a chemical proof outer garment.  The connector includes inside and outside connec-tor blocks with matching faces that sandwich the sheet material between them.  Fluid passages through the two blocks meet at respective ports in the matching faces and are joined by coupling sleeves extending through holes in the sheet material.  O-rings around the ports seal the holes through the sheet material.  A cap screw or the like secures the two blocks to one another.  The connector is equipped with valve male fittings and male lock components of a standard connector system that is now used for personal cooling garments.
