Abstract: INTEGRAL FOLDABLE PACKAGE     Abstract of the Disclosure An integral package for a cassette type article com-prising a foldable member having first and second cover walls pivotally connected to a spine wall to form a book-like con-tainer, and having disposed between the cover walls a rec-tangular tubular compartment.  The compartment has a side panel provided with a slotted opening dimensioned for re-ceiving therein at least a portion of the article, and is disposed with respect to the spine wall for retaining the article in the compartment when the container is closed.          The foldable member also may have a flap portion integrally connected to one of the cover walls along a perforated edge to provide a support hanger which may be used to support the package in retail displays and may be readily removed when the package is stored, similar to a book on a shelf, for example.  The package may be enclosed in a shrink wrapping of clear plastic material, and has at least one open end portion whereby the presence of an article in the compartment may be ascertained without removing the wrapping and opening the book-like container.

Abstract: DEWATERING FINE COAL SLURRIES USING  TWO TYPES OF ORGANOPOLYSILOXANES                        ABSTRACT           Aqueous slurries of fine coal are dewatered by a process which comprises mixing a mixture of a water-soluble organopolysiloxane and a water-emulsifiable organopolysiloxane with the slurry, separating the slurry to recover the fine coal and further drying the fine coal, if desired. The use of a mixture of a water-soluble organopolysiloxane and a water-emulsifiable organopolysiloxane unexpectedly provides improved separating and/or improved drying or fine coal compared to a dewatering process that uses only one of the organopolysiloxanes.

Abstract: CONTROLLING TEMPERATURE OF A CRYOGENICALLY         REFRIGERATED PRODUCT                       ABSTRACT         The temperature of a product which is being chilled in a blender by introducing carbon dioxide in solid and gaseous form into the blender is controlled by sensing the power drawn by the drive motor coupled to the impeller.  The power drawn by the motor is sensed and analyzed and, upon reaching a pre-determined value, the introduction of CO2 into the blender is terminated.  As the product is chilled by contact with CO2 in the blender, the viscosity of the product will increase, which in turn, increases the power drawn by the motor.  Variations in line voltage supplied to the motor and changes of the initial temperature of the product being chilled do not affect the final temperature to which the product may be accurately chilled.

Abstract: METHOD AND APPARATUS FOR IDENTIFYING OBJECTS          ABSTRACT          Disclosed is a method and an apparatus for identi-fying objects, such as articles sold in a store, appearing in a random position and orientation and at random times on an image window.  On a surface facing the image window, each object has an identification in the form of a field which comprises on at least one data track contrasting indicia with at least one contrasting line pattern identifying the posi-tion and the orientation of the data track. The track also includes a pluraligh of parallel lines with variable spacing and/or line widths.  The image window is scanned line-by-line to generate a vinary video signal which corresponds to the scanned contrast sequence.  The length of the overlapping light and dark intervals of the video signal resulting from the scanning of the line pattern is measured and successively measured interval lengths are compared with each other and a comparison signal having a first amplitude is generated when the two interval lengths which are being compared have a predetermined ratio to each other which conforms to the spacing of corresponding pattern lines.  An identification signal is emitted when during each of a number of successive comparison steps, the number of which is determined by the contrasting line pattern, a reference signal having the first amplitude is generated.

Abstract: ABSTRACT OF THE DISCLOSURE           A support tube for a tubular structure, such as a vertical post for a railing, a ladder step, or the like, has at least at one end a curved recess for receiving a cross tube.  On the curved margin of the curved space, the wall of the supporting tube is bent to form a supporting flange.  This is made by, prior to cutting the supporting tube to desired length, drilling a hole through the tube at the point where it is cut, and drawing out the margins of the hole to form a collar projecting from the support tube.  The support tube is then cut off so as to divide the collar into support flanges, which remain on the ends of separate support tubes.

Abstract: Abstract of the Disclosure This invention concerns a device for automatic circula-tion in waste water pump stations.     The pump unit is provided with a valve directly at the pump housing to open a connection between the pump and the pump station.  By operation of the valve, circulation of the waste in the pump station is obtained.  The valve is arranged at the upper side of the pump housing and has an outlet which is oriented in a direction within 45° to either side of the direction directly opposite to the direction of flow of the waste at the location where the valve is connected.  Thus, the risk of clogging of the valve is minimized and flexible objects which may be entrained in the medium are prevented from becoming wrapped around any surfaces at that location.

Abstract: MEMBRANE PLASMAPHERESIS APPARATUS AND PROCESS              ABSTRACT OF THE DISCLOSURE         A membrane plasmapheresis system introduces a flow of whole blood subject to a predetermined inlet pressure into a fluid path across a membrane which is suited for filtering the plasma from the whole blood and across which a predetermined pressure drop occurs.  The plasma-poor blood is conducted from the membrane subject to a determinable plasma-poor blood pressure.  Likewise, plasma filtrate is conducted from the membrane subject to a determinable plasma-filtrate pressure.  The conduction of plasma filtrate is metered in response to the existent plasma-poor blood pressure to achieve and thereafter main-tain substantial equilibrium between the plasma poor blood pressure and the plasma filtrate pressure.  A substantial-ly constant transmembrane pressure can thereby be main-tained at a level below which hemolysis occurs.
