Abstract: ABSTRACT OF THE DISCLOSURE           Powder conveying apparatus for conveying powder paint from a container to a device for applying the powder paint com-prises two flow constrictors defining vertical powder flow passages in vertical axial alignment and axially spaced apart from one another to define an annular gap between opposed ends of the flow constrictors.  A powder inlet opening communicating with the lowermost end of one of the flow constrictors is pro-vided at the underside of the apparatus and in axial alignment with the flow passages.  A vertical powder outlet passage com-municates with the other flow passage whereby the powder inlet opening, the flow passages and the powder outlet passage provide a straight-through vertical flow path.  A compressed gas supply passage communicates with the annular gap for supplying com-pressed gas through the latter, whereby powder is drawn in through the powder inlet opening and entrained along the flow path, and the flow constrictors are relatively adjustable to adjust the size of the annular gap and thereby to adjust the rate of flow of the powder through the apparatus.  A vibrator is provided for vibrating the apparatus to improve the powder flow therethrough, the compressed gas supply passage communica-ting with the annular gap through the vibrator, whereby the compressed gas both operates the vibrator and entrains the powder.  At least one fixedly open by-pass passage communicates with the compressed gas supply passage and the powder outlet and by-passes the annular gap and the second powder flow con-strictor.

Abstract: ABSTRACT       A purification process for the removal of contaminants from raw or waste waters by combined biological-chemical degradation of such contaminants comprises adding a finely divided mineral or mixture of minerals to the active micro-organisms kept in the reaction system and contacting the incoming waste waters with the formed active sludge.  The added mineral or minerals which are essentially insoluble in water and non toxic to the micro-organisms increase the density of the formed active sludge.  Through dissociation of the mineral, the ions assist in precipitating ionic species present in the processed waste water and in controlling the pH therein.  The yield of the simultaneously occuring biochemical and chemical reactions is thereby enhanced.      Apparatus is disclosed in which the process may be conducted.

Abstract: ABSTRACT             A gauge for monitoring the height of liquid contained in a storage tank or the like, comprising a channel-like structure having a first elongate probe element constituted as a circuit board having a conductive strip running for a substantial length therealong, an additional upright probe element also constituted as a circuit board, coextensive with the first and also having a conductive strip running for a substantial length therealong, and an elongate member disposed along the boards and constituting a spacer for maintaining the conductive strips of each of the elements in substantially parallel relation.  Means are provided for mechanically con-necting the boards to the spacer, with both probe elements be-ing adapted for immersion in the liquid being gauged.  In ad-dition, means are provided for impressing a voltage on the con-ductive strip of one probe element, and additional means for de-tecting voltage induced or sensed on the conductive strip of the other probe element, the latter voltage being a function of the immersion of the elements in the liquid being gauged.  By the invention there is no dielectric material in the area be-tween the conductive strips.  The advantage of the present con-struction over prior devices is that the likelihood of debris and residue in the tank bridging the gap between the strips is greatly minimized, since there is complete access of the fluid to those portions of each board which carry the strips.  Improved performance and accuracy over extended periods of use thereby result.

Abstract: PROCESS FOR THE DIRECT PRODUCTION OF STEEL               ABSTRACT OF THE DISCLOSURE           A process for the direct production of steel from particulate iron oxides or concentrates including two major steps in which in Step (1) the iron oxides are converted to iron carbide and in Step (2) steel is produced directly from the carbide in the basic oxygen furnace or the electric furnace.          In the production of the carbide the oxides are reduced and carburized in a single operation using a mixture of hydrogen as a reducing agent and carbon bearing substances such as propane primarily as carburizing agents.  Iron carbide thus produced is introduced as all or part of the charge into a basic oxygen furnace to produce steel directly without the blast furnace step.  In order to make the steel making process auto-thermal, heat is supplied either by using the hot iron carbide from Step (1) or preheating the iron carbide or by including sufficient fuel in the iron carbide to supply the required heat by combustion.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification discloses a method and apparatus for laboratory testing of carburetors to determine the mass air flow rate and mass fuel flow rate through the carbutetor at any desired test point by providing, in addition to the normally required systems, an improved manifold vacuum control sys-tem for producing a predetermined air flow at a given manifold vacuum, and an improved hood pressure control system which en-ables carburetor testing to take place at test points which cor-respond to different altitudes in which the carburetor may be used.  In addition, by providing that these systems be computer controlled, the three-mode controllers normally associated with producing air flow and controlling hood pressure are replaced by a computer which provides output control signals correspond-ing to that which would be provided by three-mode controllers where the values of rate, reset and proportion are continuously and automatically changed to the optimum value for each test point.  In this way it is now possible to perform the laboratory carburetor test completely automatically at many test points in the carburetors operating range more quickly, accurately and reliably, whether or not testing is required at sea level or at any altitude within practible limits.
