Abstract: Abstract of the Disclosure A feathering valve system for modulating the fluid inflow to a selected one of first and second spool ends of a spool valve assembly.  A controller is electrically coupled to first and second solenoid operated pilot valve assemblies for selectively (13 maintaining the pilot valve assemblies in a valve closed state without bleed flow through the pilot orifices or (2) supplying a predetermined value electrical signal to either, but not both, of the valve assemblies for actuating one of the assemblies to an open position related to the value of the signal.  Fluid under a substantially constant pilot pressure is applied under the poppets of both valve assemblies.  Fluid flow is taken from above the poppet of an actuated valve assembly to a respective spool end whereby the spool moves to a position which is a function of the actuating signal value.

Abstract: INCINERATION METHOD AND APPARATUS                 Abstract of the Disclosure A method and apparatus for incineration of com-bustible material including the processing of sewage sludge from wastewater treating plants and the initial activation and regeneration of activated carbon granules or powder used for absorption in wastewater treatment and the like.  The method is carried out by supporting the combustible material in an enclosure, directing infrared radiation on the material, and controlling the atmosphere in the enclosure around the material for purposes of controlling the oxidation process initiated by the heat from the infrared radiation.  In a more specific form the method includes a step of counter-flowing combustion gases over the combustible material to supplement the infrared heat.  The combustion chamber of the enclosure is operated at a slight vacuum to minimize escape of noxious odors.  In practicing the method with sewage sludge, the sludge is first pre-dried and fragmented before intro-ducing it into the enclosure.  In the enclosure the sludge is burned by the combined heat of the infrared and counter-flowing combustion gases to incinerate all combustible material in the sludge.  When applied to carbon particles, the method comprises the burning of bonding agents and other foreign matter present in the carbon when the carbon is initially activated, and when the method is applied to regeneration or reactivation of the carbon, the contaminants on and within the carbon resulting from the adsorption process are burned from the carbon with the atmosphere controlled to prevent oxidation of the carbon itself.

Abstract: ABSTRACT OF THE DISCLOSURE     Polyacetal scrap materials may be reclaimed and degradation of the polymer and undesirable loss of elongation avoided, by intimately admixing with the material about 2% by weight of a polysiloxane fluid.      Polyacetal resins such as may be prepared by polymeriz-ation of formaldehyde with from 0.1 to 15 mol. % of a cyclic ether, i.e. ethylene oxide, after reduction by usual machining processes to scrap, may be coarsely ground to between 1/8 and 3/16 inch in greatest dimension, mixed with a silicone fluid, and extruded as by a Werner-Pfleiderer or other extruder at operating temperature of extrusion die about 205°C to form strands; these are immediately cooled in water, chopped and dried to form molding stock.  An optimum proportion of a polysiloxane fluid which preserves  elongation up to 56% and tensile strength nearly 8,000 psi is 2%; a lesser proportion preserves higher strength but lowers elongation, and higher proportions lower both tensile strength and elongation. One suitable polysiloxane has a viscosity about 30,000 centistokes.

Abstract: ANTI-VIBRATION THREAD INSERT     ABSTRACT OF THE DISCLOSURE:         A locking thread insert is wound from wire which is drawn to a generally diamond-shaped cross-section. The wound wire is coiled to a predetermined diameter preferably slightly larger than the diameter of a threaded hole in a female member in which the insert is to be disposed. The threaded screw is free-running in the insert until a predetermined magnitude of loading is encountered at which time a locking and anti-vibration interaction occurs between the crest of the male thread on the screw and the insert. The crest of the male thread is radially compressed when moved axially and circumferentially so as to positively resist loosening under vibration.          The interaction between the insert and screw also positively seats and locks the insert in the female member.

Abstract: ABSTRACT OF THE DISCLOSURE                A system for forming zigzag wire binder material in a continuous strip, storing the strip as it leaves the forming station, and severing lengths as needed at an adjacent station at which the binder lengths are inserted in books. The invention permits the binder strip forming mechanism and the binder cutting and inserting unit to be at a single location because the storage mechanism placed between these two units is responsive to speed differences between the strip forming and binder inserting units to temporarily stop one unit or the other until the length of binder strip in the storage unit is brought within a certain range.          The inserting unit has novel means for forcing the opposite ends of the binder loops into the book holes, making the unit especially useful for heavy count books. This novel inserting means includes two series of pins which move in opposite directions to force the loops into the holes.
