Abstract: METHOD FOR REMOVING HYDROGEN              SULFIDE FROM GAS STREAMS               Abstract of the Disclosure The problems of chemical consumption and undesirable formation of sulfur-containing salts inherent in conven-tional processes, such as the Stretford and Takahax processes, for the removal of hydrogen sulfide from gas streams are substantially reduced by the use of a novel, substantially quinone-free washing solution containing solubilized vanadium, thiocyanate ions, a carboxylate complexing agent and one or more water-soluble nonquinone aromatic compounds capable of solubilizing vanadium.          Hydrogen sulfide is removed from the hydrogen sulfide-containing gas stream (12) by contact with the washing solution (14).  The absorbed hydrogen sulfide is converted to elemental sulfur by reaction with the washing solution.          The sulfur is separated (36) and recovered.  The washing solution is oxidatively regenerated (24) before being recycled (30) to the absorber (10).

Abstract: ABSTRACT OF THE DISCLOSURE             A method and apparatus for forming a fibrous web between a pair of forming wires.  The apparatus includes an imperforate rotatable roll and a pair of liquid permeable forming wires which meet about a portion of the surface of the rotatable roll.  Means are provided for delivering a liquid suspension of fibers between the forming wires as the wires are being received about a portion of the rotatable roll.  The specific improvement of the present invention is centered around an arcuate imperforate roof conforming to the periphery of the rotatable roll along a limited part of the portion in which the twin wires are forming the sheet, with injection means for injecting pressurized air along the surface of the roof to form an air film therealong.  Collector means are provided at the end of the forming portion for collecting liquid expelled from the forming wires during their travel along the portion of the roll.

Abstract: ABSTRACT           An improved method for the production of ethanol from a fermentable carbohydrate such as glucose, fructose or sucrose using the bacterium Zymomonas mobilis which method involves continuously anaerobically culturing the bacterium in a culture medium containing the fermentable carbohydrate, continuously or periodically drawing off a portion of the culture medium and replacing that portion with fresh culture medium, separating from the removed portion of the culture medium cells of Zymomonas mobilis contained therein, returning those cells to the culture medium, and recovering the ethanol contained in the portion of the culture medium from which the cells have been removed.  It has been found that this method results in greatly improved ethanol production without the disadvantages which have been found when yeasts are continuously cultured.

Abstract: ABSTRACT OF THE DISCLOSURE A single-vented fuse tube has a bore lined with an arc-extinguishing material. A movable contact moves away from a stationary contact in the bore and toward and out of an exhaust opening. An arc established between the contacts causes de-ionizing arc-extinguishing gases to evolve from the bore. The gas is exhausted from the exhaust opening. The bore is mildly tapered-to about 1° to 3° of included angle-so that its greatest diameter is at the exhaust opening. The included angle and extent of the taper are sufficient to obviate stagnation of the gases evolved deep within the bore and clogging of the bore.

Abstract: JOURNAL AND END CLOSURE FOR TUBULAR VESSELS     ABSTRACT OF DISCLOSURE A journal and end closure for a tubular vessel particularly a shell supported tubular grinding mill.  The mill shell is conventional to the point of the journal.  The journal and end closure are formed by a pair of spaced apart cylindrical members and a T-shaped ring member, each secured to one another in an end-to-end relationship by welding.  An annular plate is secured by welding to the leg of the T-shaped ring member to form part of the end closure for the mill.  The T-shaped ring member is made from a material with controlled sulphur and impurity levels.  The two cylindrical sections are rolled so that the grain structure of the metal is generally parallel to the longitudinal axis of the tubular vessel.  The dimensions of the T-shaped member are selected to prevent high areas of stress from being concentrated at the junction of the T-shaped member with the two cylindrical members and the junction of the annular member with the leg of the T-shaped member.

Abstract: ANTI-LOCK DEVICE FOR REGULATING THE  BRAKE PRESSURE OF VEHICLE BRAKES            Abstract of the Disclosure An anti-lock device for the brakes of vehicles, particularly rail vehicles, regulates the applied braking force.  An evalua-tion circuit monitors the speed, acceleration and slip of at least one braked wheel and in response to the rotational behavior of the wheel generates instructions for the brake actuating element.          The evaluation circuit maintains the brake pressure constant during the initial phase upon the first application of brakes until the wheel acceleration falls below a predetermined negative threshold value.  The initial phase is terminated when the wheel acceleration falls below a further predetermined reference value which is lower than the first threshold value.  Upon termination of the initial phase, the brake pressure is again varied in a manner as known in the art.

Abstract: ABSTRACT            The high pressures in the combustion chambers of split cycle internal combustion engines require higher voltages to be applied to spark plugs than are utilised in conventional Otto cycle engines, with the result that the working life of the spark plugs is shortened.
