Abstract: HEATED PRESS PLATE FOR CONVEYOR BELT REPAIR AND CONSTRUCTION                                 Abstract A press plate of rectangular or rhombic plan used in apparatus for repair of conveyor belts or for making them continuous by joining the ends.  The basic structure consists of a framework, a heated plate on the side to which material to be pressed is applied, an outside cover plate and a heating system having area heating elements in the form of tube-type heating elements and/or resistance heater plates of specified heat output.  The framework comprises an outer framework of four outer framing elements of equal cross-section and a plurality of tranverse equal cross-section inner framing members parallel to and equidistant from one another and parallel to two opposite sides of the outer framework.  The heating elements are arranged in the spaces between the inner framing members and spaced from the outer framing elements.  To achieve the most uniform possible temperature  distribution and to insure uniformity when several press plate units are combined to form a press plate assembly, the heated plate is divided in plan view into center heating zones (MH), transverse-edge heating zones (QH), corner heating zones (EH), and longitudinal-edge heating zones (LH).  The center heating zones (MH) are of rectangular or parallelogram shape in plan view and include one of the inner frame members running centrally longitudinally, and define a basic heating area for the heated plate.  Their corners extend to the area of the outer framing elements.  The longitudinal-edge heating zones (LH) are parallel to the inner frame members and include an outer frame element.  The transverse-edge heating zones (QH) and the corner heating zones (EH) complete the heated plate.  The specific volumes of material in all the heating zones (MH, LH, QH, EH) are equal.  The heating elements in the spaces between the inner frame members are each shared equally between two adjacent center heating zones (MH).  Those arranged in the spaces between the inner frame members and the adjacent longitudinal outer frame element are shared between the respective centre heating zone and the adjacent longitudinal side zone.  The heating elements in the center zones (MH), in the transverse-edge zones (QH), in the longitudinal side-edge zones (LH), and the corner zones (EH) have equal specific heat outputs.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns a pulp grinder in which feed devices force the wood against the grinder stone and in which there is an elevated level of water in the grinding zone. Sealing devices or plates extend between the walls of the wood-supply chutes or pusher chambers and the grinder stone to keep the water level high only in the grinding zone.  The sealing plates are adjustable for controlling the liquid level in the grinding zone.

Abstract: ABSTRACT:              A device for forming an image of an object by means of ultrasonic beans, comprising an  array of elec-troacoustic transducers, means for connecting a selected group of transducers to a delay unit which is arranged to delay the electric a signal generated by each transducer of the group by a predetermined  period of time and to sum the delayed signals in order to form a resultant signal which is an electrical representation on of the acoustic signals originating from a selected distance or from a selected direction. The delay unit is formed by a tapped delay line, whose taps serve as inputs for the signals originating from the various transducers and whose output is connected to a signal processing device for the further processing of the resultant signal. A delay unit of this kind is simple and inexpensive and can be be readily exchanged if other delays are desired.

Abstract: RECOVERY OF MOLYBDENUM AS AN AQUEOUS SOLUTION     ABSTRACT OF THE DISCLOSURE        The process of separating components of a crude reaction mixture obtained from a molybdenum-catalyzed hydroperoxide epoxidation of an olefin wherein the product epoxide and an alcohol corresponding to the hydroperoxide used are removed from the reaction mixture leaving a spent catalyst solution and sub-jecting the spent catalyst solution to a liquid-to-liquid solvent exaction to separate dissolved molybdenum values, is improved by solvent extracting the spent catalyst solution with an extract-ing medium consisting essentially of water and a water immiscible organic solvent to form a two phase system and then separating the molybdenum-rich aqueous phase extract from the organic phase extract.  The molybdenum-rich aqueous phase extract may be treated to recover the molybdenum as a solid or the extract may be treated to obtain an active molybdenum catalyst suitable for reuse as a catalyst in a hydroperoxide epoxidation reaction.

Upper and lower arrays (70,72) of the gas jet pumps are disclosed as being usable sepa-rately or in cooperation with each other in one embodiment to maintain temperature uniformity and glass sheet planarity.  Each array includes an as-sociated conduit support (74,76) that mounts the gas jet pumps thereof in a spaced relationship transverse to the direction of conveyance either above or below the conveyor rolls.  In another em-bodiment, the compressed gas supplied to the gas jet pumps (24) is heated to provide the primary source fox heating the furnace.  One gas jet pump utilized comprises a simple jet opening, while another pump comprises a restricted opening and a contoured surface along which the primary gas flow is guided, and a further pump includes a de-flector that initially guides the primary gas flow from a restricted opening along the contoured surface.

Abstract: Abstract of the Disclosure To a suspension of rare-earth phosphors and sulfidic or selenidic phos-phors there is added about 1 to 2% of the amount of hypohalide which would be necessary to convert the entire sulfidic or selenidic chalcogenide phosphor into a soluble sulfate and/or selenate.  When acidifying the dispersion to which hypo-halide has been added, to a pH value of preferably between 1.5 and 2, there is caused a sedimentation of elementary sulphur and/or selenium which becomes atta-ched to the sulfidic and/or selenidic phosphor solids, thus causing these phos-phor solids to sediment.  The supernatant suspension containing the rare-earth phosphor is then decanted, and the rare-earth phosphor is reclaimed from the sus-pension.  The disclosed reclaiming process is particularly suitable for decontam-inating phosphor mixtures as resulting in the course of manufacturing color tele-vision cathode-ray tubes.
