Abstract: IMPROVEMENTS IN METHOD AND APPARATUS       FOR FLUID FLOW CONTROL            ABSTRACT OF THE DISCLOSURE           An improved method and apparatus for parenteral  administration of medical  fluids, wherein a normally shut-off intravenous feeding tube is selectively opened at a frequency and open period duration automatically regulated by a digital control system to establish a fluid flow rate at any selected rate over a wide dynamic range.  Measured and desired flow rates are converted to digital electrical signals and compared, the electrical difference being used to vary a control voltage which establishes the width of energizing pulses controlling a member for opening the feeding tube.   The frequency of the energizing pulses is preferably a non-integral multiple of the desired drop flow rate and varies from a very high ratio, e.g. 15.5, at very low flow rates to a much smaller ratio, e.g. 2.5, at very high flow rates.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip which is bent into a generally "3" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a recessed end interlocked with a locking-member retaining nose on a slider's neck.  The base is normally urged against the spindle of the pull tab by the resilience of the strip.  The recessed end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from becoming out of interlocking engagement with the nose.  Thus the locking member is held in position on a slider body solely by the resilience of the strip, requiring no bending or deformation of any part of the slider body that would make the slider defective from an aesthetic view.

Abstract: AIR-SEALED OIL DEFLECTOR            Abstract of the Disclosure An air-sealed oil deflector is disclosed which prevents leakage of oil from bearings or a rotating shaft and which prevents the ingestion of unfiltered atmospheric air which can lead to contaminant build-up and damage to the shaft.        The air-sealed deflector includes an annular plenum surround-ing the shaft and an annular feed slot interposed between the shaft and the plenum to fluidly interconnect the plenum with the chamber between at least two seal rings immediately adjacen the shaft.  The plenum is adapted to receive a continuous flow of forced air from an air supply system including an air prime mover and means for filtering air drawn from the atmosphere which serves as the ultimate air source.  The plenum being relatively large in volume, and having a cross-sectional area large with respect to the air feed conduit to the plenum, provides a very uniform source for air flow radially inward, in a sheet-like fashion, toward the shaft through the feed slot.  The air-seal is formed as the sheet-like flow of air is released between working clearances between the shaft and the seal rings.  A perforated diffuser ring mounted in the feed slot contributes to the desired pressure distribution and eliminates detrimental viscous drag effects.

Abstract: ROLLER WITH AN ELASTIC COVER LAYER                  Abstract of the Disclosure A steel roller core is covered with an elastic cover having a polyurethane jacket.  On the inside of the cover is found a rigid, fluid-impermeable, inner reinforcing tube of fiberglass-reinforced polyester.  The thermal coefficient of expansion of the polyester tube is similar to that of steel.  A gap or space is provided between the tube and the roller core, which gap is completely filled with adhesive.  Because the jacket is seated on the rigid sleeve with prestressing as a result of thermal contraction subsequent to cooling, the cover can not separate from the roller core even under heavy loads.  The cover can be mounted on the roller core by the user within a very short time.  It is not necessary to ship the roller core to the resurfacing plant to renew the roller cover.

Abstract: Abstract of the Disclosure The invention is concerned with the clarifi-cation of waters that contain usable sludge, fibres or equivalent.  The objective is to recover the usable material, e.g., as fuel, and at the same time to prevent pollution of waters.  According to the invention, the separation of the solids, such as fibres and any other utilizable material, from the water takes place so that the water containing solid material is fed into or onto a mobile and utilizable layer of material placed on a perforated moving base, e.g. a wire-bottom conveyor (5), so that this material layer functions as a filter.          The invention is in particular suitable for the wood processing industry, wherein the water coming from the barking drum (1) is passed into a clarifier tank (7), from which the water containing fibres is pumped onto a layer of bark material carried on a wire-bottom conveyor (5), whereby the bark layer filters the water passing through the bark layer.          Likewise, water containing solids can be pumped from a waterway or clarifying basin  into or onto a bark layer placed on a wire-bottom or equivalent con-veyor to be filtered there, whereat the solids in the water remain in  the bark material and pass along with the bark material, e.g., into a dewatering drum, and the water filtered through the bark layer passes back into the waterway or clarifying tank.  The filtered warm "circulating water" collected in the upper part of the clarifying tank (7) is pumped back into the barking drum (1).

Abstract: Pressure Modulating and Reducing Valve Abstract A pressure modulating and reducing valve communicates pressurized hydraulic fluid from a pump to a hydraulically actuated clutch of a transmission at a modulated rate of pressure rise and at a reduced pressure.  In order to provide a compact valve, the valve has a pressure reducing valve spool slidably nested within a sleeve member of a load piston to provide a valving action therebetween for controlling fluid flow between an inlet port, a load port and a drain port in a body.  Movement of the sleeve member causes an increase in the pressure at the load port which causes the pressure reducing valve spool to move against a spring to establish a pressure in the load port proportional to the travel distance of the sleeve member.  Movement of the sleeve member is controlled by a solenoid control valve having a spool slidably nested within a projection of an end wall extending into a bore of the pressure reducing valve spool.
