Title: Process for the manufacture of ammonium tungstate from reduced alkaline earth metal tungstates
Inventor: KASSERRA HANS P
IPC: C01G41/00
Filed: 1976-01-29
Granted: 1979-12-18
Abstract: ABSTRACT OF THE DISCLOSURE           A process for the manufacture of a tungstate salt, especially ammonium tungstate, is disclosed.  In the process a reduced alkaline earth metal tungstate is contacted with an aqueous solution of a compound having a cation selected from the ammonium ion and/or alkali metal cations and at least one anion selected from hydroxide, carbonate, bicarbonate, oxalate and phosphate.  At least one of the anions is an anion from which an insoluble compound of the alkaline earth metal is derived,  the anion being in a concentration such that the insoluble compound is less soluble in the solution than the alkaline earth metal tungstate,  The solution also contains an oxidizing agent, e.g. oxygen, hydrogen peroxide and per-oxides of alkali metals.  me process may be used in the separation of tungsten from scheelite, or ores convertible thereto.

Abstract: ABSTRACT OF THE DISCLOSURE           The hydraulic actuated power tool includes a barrel having an internal, annular bulkhead separating the barrel into two cylinder chambers. A single piston shaft having two pistons thereon operates within the cylinders of the barrel. One of the pistons is located intermediate the shaft ends and the other is positioned at the terminal end of the piston rod. This latter piston serves as the back wall for the rear cylinder chamber. The piston shaft is ported so that in the power stroke both pistons are being urged rearward, whereas in the return stroke only the for-ward piston is being acted upon. The porting includes a transverse port extending across the piston shaft and a longitudinal port connecting midway of the transverse port and extending along the piston shaft and terminating in a bifurcated passageway which extends through the forward piston. A floating front wall makes up the end wall of the forward cylinder. The rear piston is attached at the terminal end of the piston shaft through a split retainer ring.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method and a device for causing ignition in a gas planing process, for removing work-piece defects in a steel rolling mill.  The method is based on applying heat to a workpiece by means of a movable heat source, which has a point effect so that the heated or molten portion of the workpiece forms a strip which extends perpendicularly to the flow direction of the planing oxygen.  The device for carrying out the method comprises one or more planing burners and one or more movable ignition means so connected to the burner that the ignition means can move relative to the planing burner both in parallel with and perpendicularly to the planing direction and at the same time carry out the function of a heat source of point shape, which preheats a strip-shaped zone on the surface of the workpiece and/or in addition to said preheating adds molten metal to said zone.

Abstract: BENDING GLASS SHEETS                        Abstract of the Disclosure Method and apparatus for bending glass sheets using a relatively lightweight, low cost bending mold of the outline type comprising a plurality of closely spaced shaping rails, each being rigid along its longitudinal dimension and its transverse vertical dimension and less rigid in its transverse horizontal dimension and mounted for micrometer adjustment in an essentially horizontal direction only to accommodate the mold to slight changes in mold outline.  Only one set of molds constructed according to the present invention is needed to bend glass sheets of slightly different outlines to a desired shape for insertion in windshield receiving frames of automobiles of slightly different sizes. In the method of this invention, glass sheets are supported on such molds at a plane of support that is at a slight oblique angle downward in the downstream direction of glass sheet movement through a bending lehr in order to avoid slippage of glass sheets relative to the mold when the latter starts suddenly and to provide a more uniform heating pattern across the width of glass sheets conveyed transversely through a bending lehr provided with overhead heaters.
