Abstract: INVENTION:  FUEL INJECTION SYSTEM WITH PRESSURE EXCURSION       START INHIBIT          INVENTOR:  EMILE DAVID LONG                      ABSTRACT OF THE DISCLOSURE           A fuel injection system for a spark ignition internal combustion engine employs at least one electrically energized injector. The injector connects to a fuel supply line which receives fuel from a source and is maintained at substantially constant pressure during engine operation by an engine powered fuel pressure booster.  The injector is energized by a variable width electric pulse generator controlled by a sensor measuring engine operating parameters.  A control circuit prevents the injector from providing fuel to the engine during start condi-tions until satisfactory pressure is obtained within the fuel line.  The control circuit receives the output of a pressure switch connected to the fuel line and provides a signal that inhibits energization of the injector when the fuel line pressure is below a predetermined value.

Abstract: ABSTRACT            The device for provisionally supporting a gallery or a tunnel which definitely shall be supported by support frames closed on all sides comprises a floor girder which serves as a part of the provisional frame as well as of the definite one. For the provisional support said floor girders are laid out separately near the mining face. Only U-shaped elements which are reduceable in profile are to be brought forward through the inner width of the positioned frames. These U-shaped elements may be connected with the said floor girders to form a complete provisional supporting frame closed on all sides. Such provisional support fulfills absolutely the safety requirements, and setting the definite frames may be carried out quickly and without long lasting interruptions of biasing the roof because the provisional floor girders remain usable as floor girders for the definite supporting frames, too. 1979/03/20 kr

Abstract: Case 78109 COLD-WATER-DISPERSIBLE LECITHIN CONCENTRATES ABSTRACT OF THE INVENTION Cold-water-dispersible lecithin concentrates are prepared by a homogeneous blend of lecithin and certain nonionic emulsifiers (e.g., polyoxyethylene mono- and diglycerides and polyoxyethylene derivatives of partial fatty acid esters and hexitol anhydrides). The concentrates readily disperse into cold water (e.g., under 5°C.) over a broad concen-tration range (e.g., 0.05-30%) to form low-viscosity and stable lecithin in water emulsions. Concentrates containing polyoxyethylene mono- and/or diglycerides are particularly effective emulsifiers for the lecithin concentrate.

Abstract: ABSTRACT OF THE DISCLOSURE             Either sulphur-containing raw materials or sulphur-containing fuels may be used in the calcination of mineral raw materials in a calcining furnace, with significant desul-phurization of the calcined material being achieved if, on the one hand, cooling air introduced into the cooling zone of the furnace is removed at the upper end of the cooling  zone thereof through exhaust ducts and if, on the other hand, the flue gases are free of oxygen and have a carbon monoxide content of 1 to 5% by volume.  In order to obtain this composi-tion of the flue gases, the combustion process can either be performed in the calcining zone of the calcining shaft of the furnace with a deficiency of air or a gaseous, liquid or solid fuel can be supplied by means of fuel tubes located at a transfer duct between the furnace shafts.

Abstract: ABSTRACT OF THE DISCLOSURE In the alkaline pulping of cellulose and particularly in the step wherein green liquor is converted to white liquor by causticizing or the addition of calcium hydroxide, it has been found that the addition of any of three specially selected organic phosphonate reagents, namely, nitrilotris (methylenephosphonic acid) (Dequest* 2000); 2-phosphonobutane-1,2,4-tricar-boxylic acid (Bayer*PBS-AM); and hexamethylenediaminetetrakis(methylene-phosphonic acid) (Nalco*7691/Dequest 2051), accelerates the speed of the reaction to the right.  These acid compounds and their soluble alkali metal and ammonium salts have proved effective in increasing the acceleration rate to the right of the causticizing reaction and the production of the titratable sodium hydroxide   These additives give up to a 2-4 % increase in causticizing conversion to NaOH when applied at .5 - 2 % active based on the theoretical yield of cal-cium carbonate and this has been observed above the usual percent conversion ranging from 85 - 90 %.  Other materials including other phosphonates such as l-hydroxyethylidenedisphosphonic acid (Dequest 2010) and sodium poly (.alpha.-hydroxy-acrylate) were not active or retarded activity as to acceleration.     * trademarks

Abstract: ABSTRACT OF THE DISCLOSURE            Seamless cans are drawn and ironed from steel sheet having a very thin coating of nickel on both sides.  The steel may be flat rolled blackplate and the nickel may be plated onto the steel by drawing a continuous strip or sheet of the steel through a conventional electroplating bath to deposit the very thin nickel coating.  The coated steel is cut into blanks which are drawn into cups, and the side wall of the cups are then ironed in the conventional manner to produce the desired thickness and height for the finished cans.  The nickel coated steel may be chemically treated to increase storage life of the material before drawing and ironing.  The drawn and ironed cans may also be chemically treated to enhance the adhesion of lacquer applied to the cans.
