Abstract: "RELEASABLE PUSH-TO CONNECT TUBE FITTING"                 ABSTRACT OF THE DISCLOSURE    A releasable push-to-connect tube fitting wherein a collet receiving the tube end is provided with longitudinally extending inner slots sized so as to limit constriction of the collet to maintain the outer diameter of the inner end of the collet greater than the minimum diameter of a confronting camming surface of a fitting body member for effectively positively retaining the collet in the body member upon assembly of the fitting elements.  The collet includes an enlarged outer end exposed exteriorly of the fitting body for use in releasing the tube from the fitting when desired.  The collet is retained in the body by constric-tive deformation of the body outer end portion after installation of the collet therein.   The constrictive deformation is effected by a suitable tool.  In one embodiment, the fitting body is adapted to be secured in a port element.  An eyelet may be provided for reception within the tube end to be connected to the fitting.  The collet may be selectively provided with a plurality of tube biting teeth or a helical tooth.

A series of substantially parallel,  projecting  ribs are optionally provided onto both surfaces of  said  core.  The  liners  are formed by cold- or hot-pressing to  fit  to said ribs in the case where ribs are provided  onto  the  core.  Alternatively,  parallel ribs are fixed to the  liners, in the case where the core has no ribs.          Said   liners  have  peripheral  projecting  flanges.  Planar electrode  screens are electrically connected to said ribs of said liners.

Abstract: ABSTRACT OF THE DISCLOSURE         An image processing apparatus comprises a character extraction unit for extracting an area whose density distribution characteristic meets a predetermined condition such as a binarization threshold and a size and a type of local filtering, from an input image of multiple gray levels, and extracts an object area as an output image from the input image by using the charac-teristic extraction unit.  Area designation means designates an area having a uniform density distribution and containing the object area, to the input image.          Condition determination means determines the condition for the characteristic extraction unit based on the density distribution characteristic of the input image in the designated area.  In an image processing expert system, the image characteristics of the object image and the background in the area designated by the area designation means are evaluated and analyzed and the inquiry in the form of message is effected to quantize the evaluation of the image characteristic.  As a result, the area extraction procedure can be easily executed by the interaction with an operator.

Abstract: ABSTRACT OF THE DISCLOSURE Facility for characterizing the weight, physical state  and  isotopic  content of radioactive waste bearing containers  is  provided.   Containers  are  supplied  to  a weighing station where the weight density of the contents may be determined.  A conveyor then takes the container to a turntable where the entire container is scanned for gamma radiation  to help determine  the  isotopic  content.   The gamma source located on the opposite of the turntable from the gamma scanner allows calibration of the gamma scanner and  compensation  for  attenuation  of  radiation  by  the container.  A conveyor then takes the waste container to a second turntable where it is x-rayed to detect vibrations in  free  liquids  within  the  container   A predetermined fraction of the containers is then directed to an active neutron analyzer  to  determine  the  characteristics  of neutrons emitted from the container.  The remaining frac-tion of drums bypasses the active neutron  analyzer.   In either case the drums are then removed from the character-ization station.  A calibration container containing waste of known isotopic  content may  also  be  included  in  the system and periodically pass through the system to properly calibrate all stations.

Abstract: ABSTRACT           The  communications  adapter  provides  an  interface  between automotive  vehicle  on-board  computer  and  a  test  computer  running diagnostic software.  Using a dual-ported random access memory,  the circuit receives serial data from the on-board computer, preprocesses that data into a standardized data format, and places the standardized data directly into the memory space of the test computer.  The dual-ported memory may be placed at a user selected address within the memory space of the test computer,  so that it will not conflict with the diagnostic program running on the test computer.   The invention is readily upgradable by uploading preprocessor software into random access memory, thereby making the invention upwardly compatible as new makes and models are introduced.

Abstract: The invention concerns a process and a device for automatic transfer of garments (3) to automatic folding machines (2), a conveyor coathanger (8) and a tow hook (11), specifically designed for this purpose, a device (25) for removing the coathangers and a device (38) for transferring the coathangers. The garments (3) are conveyed on a conveyor section (6) and are placed and held on the inclined work surface (4) of the automatic folding machine (2). In order to remove the supporting coathangers (8), the latter are displaced over a corresponding inclined section (10) of the conveyor device (1) in the direction of slope of the work surface. The conveyor coathanger (8) has arms (13) with closed ends designed as expanding springs. The expanding springs have a dead centre position beyond which they open or close automatically, depending on the direction of movement. The device (25) for removing the coathangers, in co-operation with the tow hook (11), ensures reliable removal and opening of the empty coathangers.

Abstract: The invention provides a process for the preparation of formic acid by hydrolyzing methyl formate with water at high temperature and pressure in the presence of a formic acid catalyst. Methanol is also formed. The reesterification of the reaction products to methyl formate (a reaction favored by high temperatures) is minimized by flashing the reaction product at relatively low pressure and temperature and thereafter distilling the residual liquid. Thus procedure separates the methyl alcohol from the formic acid with a minimum contact time and at a low temperature which does not favor the reesterification reaction. High purity formic acid may be obtained by subjecting the bottom from the vacuum distillation of further distillation. 
<??>In a preferred embodiment of the invention, prior to the main hydrolysis, the methyl formate is partially hydrolyzed to form the small amount of formic acid needed to accelerate the main hydrolysis step. Accordingly, the necessary formic acid catalyst is formed in situ, thus eliminating the need to add formic acid or to recycle product formic acid.
