    Abstract: In cleaning plate-shaped objects a tub is filled with a cleaning liquid and contains a plurality of troughs mounting brushes for cleaning the objects. At least some of the brushes are arranged in pairs, with each brush of a pair rotating in the opposite direction. The plate-shaped objects are conveyed across and above the tub and the brushes are arranged so that the periphery of each brush extends above the top of the tub and contacts the objects to clean them. By rotating each brush of a pair in opposite directions, a meniscus of cleaning liquid is formed between them that contacts the objects and aids in cleaning them.

    Abstract translation: 在清洁板状物体时，桶中装有清洁液体，并且包含多个用于清洁物体的刷子的槽。 至少一些刷子成对布置，每对刷子沿相反方向旋转。 板状物体被输送到桶的上方和上方，并且刷子被布置成使得每个刷子的周边在桶的顶部上方延伸并接触物体以将其清洁。 通过以相反的方向旋转一对刷子，在它们之间形成清洁液体的弯月面，这些弯液面与物体接触并有助于清洁它们。

    CPC classification number: C21D8/005

    Abstract: The toughness of a martensitic, air-hardening steel is increased by a novel combination of steps practiced in the course of hot working a billet of the steel. After a partial reduction of the billet the billet is reheated to a temperature at which carbides are dissolved, whereupon the reheated billet is worked to final dimension under conditions to bring about a complete recrystallization in the workpiece, after which the reduced workpiece is cooled so rapidly that precipitation of carbides in the austenite grain boundaries is substantially avoided.

    Abstract: A coating doctor blade having a chamfered face is produced by the steps of forming into a roll a hardened and tempered metal band blank, edge-grinding the blank in the roll, winding off the blank, planing a chamfer surface on one side surface of the blank by moving the blank, in a single pass in the longitudinal direction of the blank, over a single hard metal bit thereby providing a chamfered surface free from scratches and grooves detrimental to the evenness of a coating spread by the resulting doctor blade, and dividing the so-chamfered blank into doctor blades of suitable lengths.

    Abstract: AN APPARATUS FOR REMOVING GREASE, OIL AND FAT FROM ARTICLES CONSISTS OF MEANS FOR BOILING A SOLVENT SO THAT THE VAPOR FILLS A CHAMBER IN WHICH THE COOL ARTICLES ARE PLACED. THE ARTICLES ARE SITUATED IN A ROTATABLE CYLINDER WHICH MOVES THE ARTICLES DOWN INTO THE VAPOR ZONE AND UP FROM THE VAPOR ZONE. THE CYLINDER IS OF SUCH A SIZE THAT IT NEARLY FILLS THE CROSS SECTIONAL AREA OF THE APPARATUS, THUS REDUCING THE LOSS OF SOLVENT FROM THE VAPOR ZONE.
