Abstract: DYNAMIC RANDOM ACCESS MEMORY            ABSTRACT OF THE DISCLOSURE     A dynamic random access memory (10) receives a memory address of a row decoder (14) which charges a selected row line (18).  When the row line (18) is charged an access transistor (24) in a memory cell (22) is rendered conductive to connect a storage capacitor (26) to a bit line (30).  The bit lines (30, 38) are previously set at an equilibration voltage. The voltage on the bit line (30) is driven slightly above the equilibration voltage if a high voltage state had been stored in the capacitor (26) or the voltage on the bit line is driven slightly below the equilibration voltage if a low voltage state had been stored on the capacitor (26).  A sense amplifier (44) is connected to the bit lines (30, 38) and upon receipt of a latch signal (L) drives the one of the bit lines (30, 38) having the lower voltage to a low voltage state.  A pull-up circuit (60) drives the voltage on the remaining bit line of the pair to a high voltage state, restoring the memory storage capacitor (26) to its initial state. After the row line (18) is now discharged trapping the original data state in the. storage capacitor (26), precharge transistors (50, 52) then connect together the bit lines (30, 38) through a latch node (46) to share charge between the bit lines (30, 38) and drive the bit lines (30, 38) to the equilibration voltage.

Abstract: ABSTRACT OF THE DISCLOSURE        A heat-insulating window pane comprises at least one cavity which has no communication with the external faces of the pane.  The cavity is evacuated to a gas pressure below 0.1 mbar. There are bridging members in the cavity.  These bridging members extend transversely of the pane.  The pane is easy to handle and its transparency properties are good because the cavity extends approximately to the marginal por-tions of the pane and occupies less than 20% of the total volume of the pane.  The total area of the bridging members in a lengthwise section through the glass covers less than 10% of the area of the pane.  The pane is relatively cheap to produce and does not constitute a risk of implosion because of the low volume of the cavity.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to a collapsible container comprising a bottom wall, and four side walls.  The upper portion of each side wall is pivotable about a horizontal pivot axis between an erect condition, wherein it extends substantially normal to the bottom wall, and a collapsed condition. The pivot axis of each side wall is at a different height than the pivot axes of the side walls adjacent to it so that in their collapsed condition the side walls lie substantially parallel to the bottom wall.  Fastening means secure the side walls when in the erect condition to form a continuous enclosure around and above the edges of the bottom wall.  Each wall is formed of plastics material.  Each side wall is of a planar construction and is constructed of two spaced confronting panels interconnected around their edges.  Means brace central areas of the two panels of each wall in fixed relation to each other.

Abstract: ABSTRACT OF THE DISCLOSURE             An apparatus for volumetrically dosing particulate matter, such as tea to be loaded into bags, comprises a housing whose lower part is kept filled through a hopper with the mass of particles above the top of a dosing drum which is intermittently rotatable just above the housing bottom about a generally vertical axis and has several outwardly open, angularly equispaced through-going peripheral notches of constant horizontal cross-section. A discharge compartment of the housing accommodates a segment of the drum, including two of its notches, and has an entrance gate closely hugging the drum surfaces that only the particles occupying a notch can reach that compartment. A first plunger then enters an incoming notch from above and expels a predetermined fraction of its contents into an underlying trough from which the resulting overflow is recirculated by a screw conveyor to the interior of the housing outside the metering compartment; after  a partial rotation of the drum, a second plunger enters the same notch from above and ejects its remaining contents into a discharge spout aligned therewith.

Abstract: ABSTRACT A raster scanner with linear scanning array, a scanning slit permitting the array to view a document image one line at a time, and document transport for transporting documents past the scanning slit. To accommodate the disparity between scanning rates and user data rates, a relatively small buffer stores lines of pixels output by the array pending user demand. Intermittent operation of the scanner in response to buffer pixel demands is effected through starting and stopping of the document trans-port. A control is provided to prevent uneven spacing of scan lines resulting from scanning stopped documents or documents in the process of being accelerated or decelerated to and from scanning speed by the document transport.

Abstract: Abstract of the Disclosure A continuous method and apparatus for the effi-cient production of gaseous chlorine dioxide by the reaction between gaseous sulfur dioxide and an aqueous solution of a metallic chlorate.  The chlorate solution and a highly concentrated sulfur dioxide gas are introduced  into a packed columnar chamber at closely adjacent locations at the bottom of the chamber so as to flood the chamber and maximize both the contact area and contact time of the two reactants. Throughout the reaction the chamber is sub-jected to high vacuum imposed by an eductor which exhausts the chlorine dioxide gas and spent reactants.  For use of the chlorine dioxide to produce potable water or treat foodstuffs, the chlorine dioxide and spent reactants are exhausted from the chamber separately by respective eductors substantially balanced with respect to each other to impose comparable vacuums upon the chamber.  Because of the high efficiency of the reaction, substantial heat is generated therefrom which is absorbed by a coolant flowing through a jacket surrounding the chamber. The flow rate of the coolant and flow rate of the reactants into the chamber are proportional due to the dependency of the reactant flow rate on the coolant flow rate.
