Abstract: Abstract of the Disclosure Disclosed is a multi-stage hydrogen water isotopic exchange column suitable for use in producing heavy water.  It comprises, at each stage, an overlying vapor-and-water contact bed, an underlying catalyst bed and an element for collecting the water dripping from the overlying contact bed and guiding to and sprinkling the water on the upper-surface of the vapor-and-water con-tact bed of the lower adjacent stage.  The vapor-and-water contact bed consists of a closely compacted fine network structure, and the water dripping from an overlying contact bed is transferred through the catalyst bed via a water channel and is sprinkled over the upper-surface of the vapor-and-water contact bed of the lower adjacent stage.  With this arrangement a multi-stage exchange column according to this invention is guaranteed little amount of gas pressure loss and elimination of water splashing which otherwise would be caused by increasing the flow rate of hydrogen gas.

Abstract: PRINTING APPARATUS     Abstract of the Disclosure An improved, low cost, high speed, impact printing apparatus usable as a typewriter or as a machine printer is disclosed which includes a carriage translatable along a page through a rack and gear assembly and having an electronically controlled printing unit oriented to reveal the line of write and give constant printing charac-teristics independent of carriage speed.  The printing unit includes a thin, lightweight, cir-cular, bidirectionally shiftable, distensible synthetic resin band having printing characters thereon, along with a single, spring-powered impression hammer for selectively engaging and distending the band toward the page in order to print a selected character.  Printing and letter-spacing are concurrently initiated and accom-plished using only a single, windable, energy-storing mainspring and a mechanical energy trans-mission assembly coupling the rack and gear as-sembly and printer in parallel.  The transmission assembly includes gearing for withdrawing a limited, predetermined amount of motive energy from the mainspring for each printing cycle, and for distributing such energy to achieve band spin and character selection, hammer cocking, and letterspacing translation of the carriage; after the variable amount of energy required for actual printing is determined (by the required band spin to achieve character selection) remaining with-drawn energy for the printing cycle is preferably (Docket No. 16989) used for increasing carriage speed, so that print-ing can occur at a variable but statistically very high speed (on the order of fifty characters per second or greater).  During tab spacing, the character band and drive rotate and act as an airfoil governor to prevent attainment of undue, potentially destructive carriage translation speeds.  Initiation and control of letterspacing, printing and tab spacing functions are achieved through appropriate logic circuitry coupling the keyboard or other input to a pair of solenoids, with mechanical linkages between the solenoid pair and transmission assembly.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to apparatus for use in printing devices for the deposit of sheet-type recording media transported across a platen into a deposit tray area disposed above the platen.  Deposit of the sheets is carried out by means of transport or delivery rollers which seize each sheet after it has passed through a printing area adjacent the platen and lift the sheet over a lower edge of the deposit tray for stacking.  A pivotally mounted common carrier bracket is provided to carry a support wall which forms the lower edge surface of the deposit tray and the transport roller means.  The support wall has a stripper surface formed along one end thereof containing bias means for resiliently pressing the recording medium into driving engagement against the transport rollers.  The other end of the support wall is formed with intake guide surfaces for leading sheets into engagement with the intake side of the platen.  The carrier bracket is pivotally rotatable so as to enable an operator easy access to the sheet feed path and the platen.
