Abstract: Abstract Cerium sulfadiazine and compositions containing a cerium sulfadiazine, particularly cerous sulfadiazine [Ce(SD)3] wherein SD represents the sulfadiazine moiety, have been found to be useful in the treatment of burns.          Cerous sulfadiazine is prepared by reacting an aqueous solution of sodium sulfadiazine with an aqueous solution of a cerous salt, such as cerous nitrate or cerous chloride.          The resulting cerous sulfadiazine is formed as a white precipitate.  The precipitated cerous sulfadiazine, such as made by reacting cerous nitrate with sodium sulfadiazine, upon washing and drying has a melting point of 248-255°C.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus and method for forming hollow articles from plasticized materials are disclosed.  A preform is partially formed under substantially no pressure on a preform core by introducing the core into a void-free charge of plasti-cized material that is placed in a preform cavity from a source of the plasticized material.  After the preform core and preform cavity have moved together to define a preform mold space, the charge of plasticized material is subjected to a pressure forming step to form a completely packed pre-form on the core.  The preform is then blow-molded in a blow cavity by introducing blowing gas into the preform through the preform core.  Neck mold structure that strips and releases the formed article from the core is also dis-closed.

Abstract: ABSTRACT OF THE DISCLOSURE           In a process for the carbothermal reduction of alumina, carbon and alumina are supplied to a molten reaction bed in a hearth in the floor of a reactor.  The reaction bed is supplied with energy by contact with plasma or with plasma effluents.  For this purpose the reaction bed itself may form the counter-electrode for a plasma gun orbiting about the vertical axis of the reactor or there may be an intermediate counter-electrode.          In either case the hearth is preferably electroconductive to provide current path from the material in the reaction bed.          Some or all of the feed material entering the reaction bed may enter the upper end of the reactor and descend through the plasma.  At least part of the carbon may be in the form of coarse lumps which are fed to the reactor via an entry duct in counter-current relation to evolved carbon monoxide which preheats and partially scrubs it.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates to a scale system which employs a microcomputer forming an integral part of the analog to digital conversion means in which the microcomputer controls the sequence of operations for performing the conversion, accumulates and stores digital data derived during the conversion of the analog signal and combines and processes that data to provide the digital output data resulting from the conversion, all in addition to performing other scale functions.  The invention relates to an improved multicapacity weighing and computing digital scale having a triple slope analog-to-digital conversion means.  The analog weight signal is integrated for a time interval which is fixed for a given scale capacity range which would generate substantially the same integrator output level in response to a full capacity weight signal for the selected scale capacity as would be generated by a full capacity weight for all other scale capacities.          In accordance with the invention, the time interval during which the first reference DC source is integrated is extended beyond the detection of the crossover of the integrator output with its reference level.  The invention also provides an improved weight filtering arrangement which enables the full advantage of the improved converter to be obtained.

Abstract: DRILLING MUD LEVEL MEASUREMENT                    ABSTRACT OF THE DISCLOSURE          An accurate measurement of the level of drilling mud in a mud pit is provided using an ultrasonic transducer that includes ambient temperature correction.  A cylindrical metal shroud open at the bottom is positioned around the transducer.  A series of vent holes are located along the upper area of the shroud to allow the convection of ambient air.  A series of Nylon screws extend through the shroud close to the transducer to limit lateral move-ment of the transducer within the shroud.  As the shroud and trans-ducer become heated by sunlight, ambient air is circulated from the surface of the drilling mud upward to the transducer through the space between the transducer and the sidewalls of the shroud and out through the vent holes.  The chimney effect thus produced insures that the temperature correction accurately represents the temperature of the ambient air between the drilling mud and transducer.   1a
