Abstract: SWINGING DOOR PARTICLE SEPARATOR AND DEICING SYSTEM                Abstract of the Disclosure In a gas turbine engine, a duct is constructed extending axially and communicating directly, through a transverse opening, with the engine plenum.  The plenum extends upward into the engine nacelle and connects with the inlet to the compressor of the gas turbine engine.  A portion of the air entering the duct is drawn into the plenum.          The remainder is exhausted out of the rear portion of the duct.  To create inertial separation, a door is mounted on a lever arm which may be rotated between two positions.  In one position the door partially closes the entrance to the plenum causing the airflow to turn through a greater angle in order to enter the plenum.  The turning motion of the airflow divides the particles of heavier mass to the outside of the turn.  These particles will be exhausted from the rearward exit of the duct.  In a second position the door closes the rear portion of the duct so that the entire volume of air entering the duct is supplied to the engine plenum.

Abstract: Case 1391 Abstract of the Disclosure Improved apparatus for imparting visual surface effects to a relatively moving substrate material by appli-cation of discrete streams of heated pressurized fluid, such as air, to surface areas of the material.  An elongate manifold assembly, comprising a pair of elongate manifold housings and a plurality of spaced, parallel fluid stream discharge channels, is disposed across the substrate path.          The manifold housings, coupled in fluid tight relation, are constructed and arranged so that any distortion of the manifold assembly caused by differential thermal expansion is resolved to minimize displacement of the manifold to-ward or away from the substrate.  Pressurized cool fluid, such as air, is directed into selected manifold discharge channels to block selectively the passage of pressurized heated air therethrough.  The manifold is provided with heated air outlets which communicate by passageways with the manifold compartment to continuously bleed off heated air from the manifold, thereby counteracting localized cooling of the manifold adjacent the discharge channels and reducing pressure build up within the manifold when selected of the channels are blocked with the cool air.

Abstract: ABSTRACT OF THE DISCLOSURE        A  single surface electromagnetic cone clutch or braking device is disclosed which transmits torque from an input shaft to a drive plate member  through a plurality of spherical members, to a conical friction ring member and then to the out-put member.  The spherical members are located in mutually op-posing conical recesses within the drive plate member and an an-nular flange which is secured to the friction ring member.  The clutch engaging forces are Increased by the camming action of the spherical members in the conical recesses.  The drive plate member also has a flexing member which permits the drive plate member to flex axially in order to minimize back-lash noise associated with spherical balls engaging conical re-cesses.  The armature is disposed normal to the electromagnetic winding to enable a large axially directed flex path to provide for a strong clutch engaging force.  The friction ring member is threadably connected to the armature with relative movement prevented between the armature and the friction ring member by an axial wear and thread  retarder member.  The axial wear and thread retarder member biases the armature toward the pole faces of the electromagnetic winding.  This biasing force ensures that the threads in the friction ring member cooperatively engage the threads in the armature member.          The biasing force of the retarder member biases the forward flank of the threads of the further ring member into engagement with the forward flank of the thread of the armature regardless of the thread clearance between the threads.
