Abstract: PRESSURE LIMITER                         Abstract A pressure limiter for a variable displacement pump of a hydrostatic transmission and which is remotely variable and operable to reduce pump stroke when a system pressure limit is exceeded to limit torque applied to an output shaft of the transmission.  The pressure limiter has a valve with a valve member which senses system pressure and when system pressure exceeds a certain value the valve member operates to direct system pressure to a servo cylinder for the variable displacement pump to move the swashplate of the pump in a destroking direction. The pressure limiter valve has a spring acting on the valve member in a direction opposite to the force of system pressure and a piston is associated with the spring.  A remotely set variable control pressure can be applied to the piston to vary the effective force of the spring and value of system pressure at which the pressure limiter valve will open to destroke the pump.  Alternate embodiments provide for an absence of control pressure either establishing a minimum or maximum setting at which system pressure will be operative to open the pressure limiter valve.

Abstract: ABSTRACT OF THE DISCLOSURE      A rotary processor comprising a rotatable element carrying at least two annular channels and a stationary element providing a coaxial closure surface spaced apart from the rotor surface by a close clearance and operationally arranged with the channels to provide at least first and second enclosed processing passages.          The first processing passage includes an inlet associa-ted with the stationary element for receiving viscous material to be processed in the passage.  The second processing passage has an outlet associated with the stationary element for discharging processed material from the passage.  Each passage includes a blocking member associated with the stationary element which provides an end wall surface for the passage.  The blocking members are arranged and adapted so that material fed to the passages can be carried forward by the rotatable channel walls to the end wall surfaces where movement of the carried forward material is blocked and the blocked material is collected for dis-charge from the passages.  A material transfer groove is formed in the closure surface of the stationary element and positioned near the end wall surface of the first passage to interconnect the first and second processing passages so that material blocked and collected in the first passage can be transferred to the second passage.  Additionally, the processor is operated under conditions which provide a significant pressure differential between the first and second passages.

Abstract: ABSTRACT      SELF-DRILLING SCREW AND METHOD AND MEANS               FOR MANUFACTURING SAME          A self-drilling  screw having  a head at one end and a forged  drilling  end  configuration  at  the  other.    The drilling end configuration comprises a pair of longitudi-nally extending flutes which are separated by land portions and which extend through a tapered tip end to form two cutting  edges.    The  forging operation  is performed  in such a way as to promote complete formation of the tip end  and  that  may  be  achieved  by  inhibiting  material flow away  from that  tip end or by promoting extrusion of material towards the tip end.  The drilling end portion of  the  screw  is  of  elliptical  cross  section having  a minor axis in the region of 60 to 80% of the major axis, and  a  fillet  is  formed in the base  of  each flute  at the  tip  end portion of  the  flute.   Each fillet has a flat  surface  arranged  generally  parallel  to  the  screw axis and  angularly  relative  to  the  adjacent  cutting edge  of  the  tip end.  At  least one  interruption,  which may be a depression of a projection  is formed on each of  a  plurality  of  side  surfaces  of  the  drilling  end portion.  Also,  each flute may comprise two end to end portions which extend at different angles to the longitud-inal axis of the screw.

Abstract: STEAM-METERING METHOD AND APPARATUS               ABSTRACT OF THE DISCLOSURE      A steam or the like supply system has two parallel legs of supply, a first leg designed for high-demand flows and for the metering thereof, and a second leg designed for low-demand flows and for the metering thereof.

Protective features in the controller assure against response to transient changes in demand and against interruption of a valve-changing operation until the programmed change has been fully implemented.

Abstract: A clamping sleeve for pipes consists of a rubber-elastic sealing ring     and a clamping ring     which on-circles the sealing ring and has clamping plates     which are directed radially outward, are located opposite one another and are penetrated by a centrally arranged clamping screw.      The clamping screw     is supported on the clamping plates by intermediate pieces,   of which one is arranged between the head     of the clamping screw and the clamping plate, whereas the other directly forms the nut for the clamping screw. The intermediate pieces have a cylindrical cross-section, so that they sit with a cylindrical surface against the adjacent clamping plate. Furthermore, the position of the intermediate pieces is fixed at the clamping plate     by stops.        The swivelling capacity of the intermediate pieces        rela-tive to the clamping plates     makes possible an inclined position of the clamping plates    relative to the clamping screw     and relative to one another.  In this way, despite the use of only one clamping screw, perfect seating of the clamping sleeve is also ensured when pipes to be connected to the clamping sleeve have different diameters within the tolerance range.

Abstract: A METHOD OF AND MEANS FOR PRODUCING A HELICAL BAND                  Abstract A helical band is produced by applying a layer of heat-settable material on to a rotating support to one side of the axis of rotation. Heat is applied to the layer, as by the support while it rotates, for a length of time sufficient for the material in the layer to set to a required extent to form the band. The band is removed before it comes into contact with the material being applied on the support. The band is preferably made of electrically-insulating material so that it can be wound helically round and bonded to a cylindrical rod of electrically-insulating material to form a helically flanged insulator for use in an overhead electric power transmission line, the flange-forming band defi-ning along the rod a helical leakage path of substantially uniform width.

Abstract: Abstract "Method and Apparatus for Making Sulfuric Acid"     In a system using the double absorption process for sulfuric acid manufacture, a single acid circulation system and a single cooler are employed.  Acid from the exit of the air drying tower and final absorber tower are mixed in a common reservoir, while acid from intermediate absorber tower is discharged to a separate reservoir.  Acid from the common reservoir is split between the intermediate and final absorber towers and product line.  Acid from the separate reservoir is cooled and split between the drying tower and intermediate absorber tower.  The circulation arrangement reduces the cooling to one relatively high temperature location and simplifies acid strength and level control.  Only half of the bulk of the circulating acid has to be cooled and the effect of seasonal fluctuating temperatures in the drying tower is minimized.

Peri-odically the concentration of the hydrogen peroxide is increased for a short time sufficiently to be toxic to the biota at or relatively adjacent to the site of introduction, thereby increasing the perme-ability of the formation at or adjacent to the site of introduction.
