Abstract: A process for recovering in pure metal form substantially all lead from battery sludge is disclosed.  The battery sludge is desulfurized, leached with acid, and separated by filtration.  Lead is recovered from the filtrate by electrowinning.  The residue from the leaching and filtration is treated with concentrated sulfuric acid to cause the simultaneous occurring of the following reactions:     Cn(H2O)m + H2SO4  ?  nC + H2SO4.mH2O            (1) C + 2PbO2 + 2H2SO4  ?  2PbSO4 + CO2 + 2H2O      (2) up to the quantitative reduction of substantially all of the lead dioxide PbO2 and elimination of substantially all the organic substances Cn(H2O)m contained in the insoluble residue.  Lead sulfate from the above reaction is recycled to the desulfurization step.

Title: Absolute pressure transducer and method for making same

Abstract: Patent Case No. I1104362-U.S.        APPLICATION FOR                AN ABSOLUTE PRESSURE TRANSDUCER AND              METHOD FOR MAKING SAME   MILTON W. MATHIAS AND   DOUGLAS W. WILDA  ABSTRACT An absolute pressure transducer includes a hollow glass tube supporting across one end thereof a differential pressure responsive semiconductor plate having piezoresistive elements diffused therein and an evacuated sealed chamber within the tube exposed to the plate.  A method for making the transducer and providing the evacuated chamber within the tube adjacent to the plate includes the steps of mounting the plate across the end of the tube to form a first fluid-tight seal therewith, inserting a loose glass plug within the tube to define the chamber, exposing the interior of the tube to a vacuum, concurrently heating the tube in the vicinity of the plug to allow the heated tube wall to constrict around the plug in response to the internal vacuum and to fuse with the plug to form a second fluid-tight seal therewith and allowing the tube and plug to cool to trap the vacuum in the chamber.  A pressure transmitter uses the transducer with electrical connections to the piezoresistive elements in a fluid filled system for applying an external pressure to the plate to produce an output signal from the elements representative of the differential pressure between the evacuated chamber and the external pressure.

Abstract: TWIN-BELT CONTINUOUS CASTER WITH CONTAINMENT AND COOLING    OF THE EXITING CAST PRODUCT FOR ENABLING HIGH-SPEED         CASTING OF MOLTEN-CENTER PRODUCT                   ABSTRACT OF THE DISCLOSURE In continuously casting molten metal into cast product by a twin-belt machine, it is desirable to achieve dramatic increases in speed (linear feet per minute) at which cast product exits the machine, particularly in installations where steel cast product is intended to feed a downstream regular rolling mill (as distinct from a planetary mill) operating in tandem with the twin-belt caster. Such high-speed casting produces product with a relatively thin shell and molten interior, and the shell tends to bulge outwardly due to metallostatic head pressure of the molten center. A number of cooperative features enable high-speed, twin-belt casting: (1) Each casting belt is slidably supported adjacent to the caster exit pulley for bulge control and enhanced cooling of cast product. (2) Lateral skew steering of each belt provides an effective increase in moving mold length plus a continuity of heat transfer not obtained with prior art belt steering apparatus. (3) the exiting slab is contained and supported downstream from the casting machine to prevent bulging of he shell of the case product, and (4) spray cooling is incorporated in the exit containment apparatus for secondary cooling of cast product.

Abstract: FINISHING PROCESS FOR MAGNETICALLY ENCODABLE FILM WITH      DEDICATED MAGNETIC TRACKS         ABSTRACT          A virtually transparent magnetic layer is included as an additional layer in a color negative film.  Information exchange between various users of the film--such as the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film, each track being dedicated to the writing and reading of a predetermined set of related parameters.  The photofinisher-dedicated track locations fill the exposed image area of each frame.  The camera-dedicated tracks lie along the edges of the film between the film perforations, the perforations being widely spaced for this purpose.  The film finishing process of the invention responds to data on the dedicated magnetic tracks on the film to govern the film finishing process.

Abstract: The present invention relates to a method for finely-grinding minerals and similar material intended for use as filler material to a particle size appropriate for this purpose, with the aid of a mill which operates with agitated grinding medium and in which the material is ground in a substantially dry state. The invention is characterized by predetermining the stay time of the material being ground in the mill; maintaining the predetermined stay time partly by discharging ground material from the mill at a predetermined, essentially constant rate, and partly by adjusting the infeed of material to the mill in relation to the quantity of material discharged from the mill such that the amount of material present in the mill increases during the infeed of material thereto; and by interrupting the infeed of material to the mill over a predetermined short period of time when the material reaches a predetermined highest level in said mill. The invention also relates to an arrangement for carrying out the method. This arrangement is characterized in that it includes a first motor-driven device which functions to control the infeed of material, a mill for grinding with the aid of an agitated grinding medium, a perforated disc which functions to separate grinding medium from the ground material leaving the mill, a second motor-driven device which functions to maintain a substantially constant outfeed of ground material from the mill, and a level monitor which is mounted in the upper part of the mill and connected to the motor-driven infeed device. <IMAGE>
