Abstract: A B S T R A C T           A rotary pulp screening device of the vertical type is disclosed having a high screening efficiency and high capacity.  The screen provides a streamline flow of pulpstock, and  aims to supply a fairly constant flow of pulp through the screen from top to bottom, thus utilizing the full height of the screen.  The screening device includes a cylindrical housing with a vertical cylindrical screen therein, a rotary impeller mounted for rotation within the screen, the impeller having a body whose top is substantially level with the disc ring and bottom is adjacent the lower end of the cylindrical screen, the body having a shape with circular axial cross section from the top to the bottom, whose diameter increases from the top to the bottom thus leaving a larger annular space at the top, and impeller blades radiating from at least a portion of the body of the impeller and extending to within a short distance from the screen for the height of the screen. The improvement comprises at least one substantially frusto-conical shaped baffle concentric with the body of the impeller, extending down from the top of the screen-adapted to divide flow of pulp stock entering the screen-ing device, and direct the divided flows to different vertical locations on the pulp screen.

Abstract: ABSTRACT         An improved means for directing the flow of blood and blood foam onto a heat exchanger in a bubble blood oxygenator is disclosed.  An extended skirt extends from the plate where venous blood and oxygen are mixed to the top of the heat exchanger of the blood oxygenator.  Blood and blood foam flow uniformly over the mixing plate and evenly onto the heat exchanger.  Full utilization of the heat exchanger may thereby be more easily achieved.

Abstract: METAL FORMING LUBRICANT AND METHOD OF USE THEREOF               ABSTRACT         The present invention relates to a lubricant for use in the drawing and ironing of black plate steel during the manufacture of enclosed containers such as cans.  In particular, the lubricant is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body.  The lubricant comprises an aqueous solution of an active component, such as a major portion of molybdenum disulfide, together with minor amounts of waxes and other materials.          In performing the method of the present invention, a lubricant system is employed.  The lubricant system comprises a dual lubricant coating.  The first, or outside, coating is applied to that portion of the black plate steel which ulti-mately becomes the outside surface of the can body.  The outside coating is applied, such as by spraying or qravure or offset printing, at a rate of about 25 to about 200 milligrams per square foot of steel surface.  This coating is dried, as through the use of a heat source, such as infrared heat or hot air. second, or inside, coating is applied to that portion of the black plate steel which ultimately becomes the inside surface of the can body.  The inside coating may also be applied to the surface of the black plate steel in a manner similar to that used for the application of the outside coating.  After the can body is produced, the outside and inside lubricants must be totally removed.  Such removal may be achieved by washing the can bodies in an alkaline solution (pH about 7.5 to 11.5) having a temperature of about 140° to about 160° F.

Abstract: ABSTRACT OF THE DISCLOSURE              "IMPROVEMENTS IN AND RELATING TO BOILERS                     OR TANKS FOR HOT WATER"    A hot water tank particularly for a beverage brewing apparatus of the infusion type in which the hot water tank has a water draw-off tap at a position between the top and bottom of the tank and a thermostat above the outlet in the tank to the tap and a control means connected to the thermostat such that water may only be drawn off through the tap when the temperature of water above the tap outlet is at least as high as a pre-determined temperature.  The controller ensures that the user cannot draw water from the tank until the temperature of the water reaches the predetermined temperature.  A water supply to the tank bottom ensures that the tank is kept full of water and in the case of the brewing apparatus this ensures feeding of hot water to an infusion spray head.  Preferably the tap is prevented from being enabled to draw off water whilst infusion is taking place due to the provision of a control valve in the connection between the tap and the water tank.

Abstract: PROCESS FOR THE PREPARATION OF OVERBASED MAGNESIUM SULFONATES           Abstract of the Disclosure A process for the preparation of overbased oil soluble magnesium sulfonates comprises contacting an acidic gas at a temperature between about 50°F up to the reflux tempera-ture of the mixture, with a mixture consisting essentially of a sulfonic acid or salt thereof, a volatile aliphatic or aromatic or chlorinated hydrocarbon solvent, a non-volatile diluent oil, a light magnesium oxide, water, methanol and combination of promoters, wherein the first promoter is one selected from an oil soluble naphthenic acid and an oil soluble carboxylic acid or salt thereof; and a second promoter being one selected from:          (a)   wherein X is one of H, OH, NH2, CO2H, OCOCH3 and SH, and Y is one of H, CH3 and CH2CH3, wherein the second promoter is less oil soluble than the first promoter; and (b)  a water soluble C1-C6 carboxylic acid.         The volatile components are stripped from the reac-tion mixture after absorption of the acidic gas is completed, to give a highly commercially desirable overbased magnesium sulfonate.  Relatively small amounts of about 1.0 to 1.5% of the combined promoters produce overbased magnesium sulfonates of exceptionally high alkalinity value up to 500 or more, with minimum sediment.  These overbased magnesium sulfonates are useful as oil additives.

Abstract: ABSTRACT OF THE DISCLOSURE      In  a   resistive-sensor  type indicator  having  a resistive sensor whose resistance changes according to a quantity to be measured and an indicator for indicating a sensor  output  voltage  developed  across  the  resistive sensor,   when  the  resistive  sensor  is  open  due  to disconnection or malconnection of the resistive sensor, the indicator indicates a maximum reading, thus resulting in a problem such that the user cannot recognize the abnormal state.  To overcome this problem, a novel trouble detecting circuit is additionally incorporated in the indicator.  The circuit comprises a comparator for outputting an abnormal signal when the sensor voltage exceeds a reference voltage and  a  transistor  for  grounding the resistive sensor  in response to the abnormal signal.  Therefore, the indicator indicates a minimum reading  in case of resistive sensor trouble.

Abstract: Articles (specifically continuous filament) are vacuum coated with boron or boron-carbon by heating the substrate (preferably electrically) to 700-900 degrees C, pref. 750-850 degrees C, at a pressure of 10-25, pref. 13-22, Torr and admitting a gaseous hydrocarbon-substd. borane, pref. ethyldeca- or triethylborane. The coating appears non-crystalline by X-ray diffraction. In an alternative process, diborane is used and the substrate is heated at 550-1000 degrees C. Material to be coated can be a filament of silica, optionally carbon coated, or tungsten. The process yields extremely strong lightweight filaments for use as reinforcement in ultra high strength composites, and combines the strength of amorphous boron with the low density of SiO2 etc.
