Abstract: ELECTROLYTIC CELL Abstract of the Disclosure An electrolytic cell is provided which is particularly suitable for the production of oxy-halogen compounds such as sodium chlorate by the electrolysis of an alkali metal halide such as sodium chloride.  A removable casing divides the cell into a separate cell chamber and a cooling and concent-ration chamber outside of said casing; means are provided for the circulation of the electrolytic solution between the cooling and concentration chamber and the cell chamber, but there is a substantial seal against the passage of gas from one to the other.  Gas such as hydrogen is separately removed from the interior of the casing, a gas sweep is provided across the surface of the electrolyte in the cooling and concentration chamber to cool the electrolyte and evaporate part of it so as to concentrate it.  In accordance with this invention, such can be accomplished without danger of explosion.  The removable casing achieves the desired separa-tion into the cell chamber and cooling and concentration chamber while not restricting convenient access to the cells.

Granted: 1979-10-02
Abstract: FLYWHEEL TREE FELLER AND BUNCHER          Abstract of the Invention A flywheel tree feller is slidably mounted in a base and comprises a combination drive and saw chain peripherally engaging and driving a circular saw bar sprocket in flywheel rotation with no relative rotational motion therebetween.  The circular saw bar sprocket is the outer flywheel race of a ball bearing, the inner stationary race of which is supported semi-peripherally to eliminate a center hub and supporting axle thereby cross-cutting for more than the full radius of the flywheel race, rather than a lesser chord, and thus to fell larger trees.  A pusher for biasing a cut tree from falling in the direction of the flywheel feller is mounted on the base and also a pair of reaction grapples for loosely closing around a tree to hold the base against reaction displacement by the operating forces of flywheel feller and pusher.  A dual bunching assembly is mountable in place of the pusher and comprises upper and lower sets of grapples pivoted for opening and closing the upper set for additionally swinging normal to the plane of their opening and closing thereby allowing the dropping of trees without shock to the base and for picking up felled trees.  A ball race is mounted on the rear of the buncher assembly with its plane normal to the opening and closing plane of the grapples for tilting the base and buncher assembly sideways for cutting and bunching on a slope.  A back platform of the buncher assembly defines a sharp edge for cutting brush and small diameter trees and catching and holding them, and bunching them over the top when the buncher assembly and base is rotated at least more than ninety degrees downward and forward.

Abstract: PRINTER               Abstract of the Disclosure A printer responds to channel commands including coded data received over a channel from a data processing unit by printing characters represented by the coded data using an electrophotographic printing arrangement.  The coded data received by the printer is first translated into corresponding graphic codes or addresses by a translate table employing a predetermined translation code, following which the addresses are used to locate sets of character image bits stored within a plurality of character generator modules.  Each set of character image bits is used to modulate a laser scan of a printing drum to effect printing of desired characters.  Both the translate table and the character generator modules are program alterable, and the data stored therein can be loaded directly from or changed in response to data and instructions from the data processing unit.  In addition the locations of the addresses stored in the translate table can be changed to accommodate a new code for the incoming data, and the same address can be stored in more than one location in the translate table so that the same character can be printed in response to different codes of the incoming data.  New graphic characters to be added or substituted in the character generator modules are communicated over the channel in a form which includes a code identifying the particular character generator module and locations therein at which a set of character image bits is to be stored and graphic character data which is converted and reformated into the desired set of character image bits.  Pages of graphic codes can have minor changes made therein during printing to print multiple copies of various forms.  Modification data for each copy and which is communicated to the printer from the data processing unit is employed, as necessary, to modify the graphic codes of each given page on a line-by-line basis, as each different copy of the page is printed.
