Granted: 1992-02-18
Abstract: METHOD AND APPARATUS FOR SPRAY COATING                Abstract of the Disclosure In  an  open-atmosphere  flame  spray  gun  system  for spraying molten particulate material and a method of spray application, an improved eductor mechanism and flame spray gun permits a greater quantity of particulate material to be delivered to the article to be coated.  The particulate material entrained in a stream of pressurized conveying air,  a stream of pressurized burn/propelling air and a stream of fuel gas are delivered through a plurality of passageways extending through the gun body to a combustion chamber for  mixing  and  ignition.    The  streams  are delivered  in  concentric  annular  relationship  to  the combustion  chamber,  with  the  stream  of  particulate material and conveying air and concentric annular stream of burn/propelling air being directed into the combustion chamber in an outwardly expanding conically-shaped axial cross-section for enhancing the diameter and length of the flame produced by the gun and permitting an  increased quantity  of particulate material to be  melted  and delivered for coating.

Title: Integrated separator for solid and gaseous contaminants in a fluid
Inventor: YANO HISASHI
IPC: B01D19/00
Filed: 1988-10-19
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE    An integrated and compact separator for removing both solid and gaseous contaminants from fluid.   Fluid to be cleaned is introduced tangentially into a vortex flow chamber before or after filtration of the fluid. The fluid stripped of gaseous contaminants passes through pores in the outer wall of the vortex flow chamber while gas-rich fluid collected near the center of the chamber passes into a gas removal pipe extending in the chamber at its axial center.  After solid and gaseous contam-inants are removed by the separator, the fluid flows out of the separator.

Title: Method and apparatus for receiving printed products from a revolvingly driven bucket wheel of a printing machine
Inventor: HAENSCH EGON
IPC: B65H29/40

Granted: 1992-06-02
Abstract: INVENTOR:  EGON HAENSCH            INVENTION: METHOD AND APPARATUS FOR RECEIVING PRINTED            PRODUCTS FROM A REVOLVINGLY DRIVEN BUCKET WHEEL OF A PRINTING MACHINE     ABSTRACT OF THE DISCLOSURE           An outfeed conveyor is arranged beneath a rotary bucket wheel driven to rotate in a predetermined rotational direction.  A belt conveyor is arranged downstream of, and a product entrainment arrangement is arranged upstream of, the outfeed conveyor.  An endless revolving belt is guided about belt rolls of the outfeed conveyor and upon which come to bear  the  printed  products  in  imbricated  formation.          Entrainment elements of the product entrainment arrangement completely stuff the printed products into the pockets of the bucket wheel.  Upon ejection of the printed products out of the bucket wheel they are fixedly clamped at their trailing edges between a support element and extensions or cantilever arms of the entrainment elements until the entrainment elements have passed the support element and thus an intersection location between the entrainment elements and the support element.  The resiliently arranged extensions of the entrainment elements are pivoted by the support element in a predetermined direction, such as clockwise, so that the printed products are cyclically released.  There is thus formed an imbricated formation of the printed products within which all printed products are aligned and there can be maintained a substantially constant mutual spacing between the individual printed products.

Abstract: DESCRIPTIVE ABSTRACT            In order to displace a working tool at a constant speed over a surface having a random shape and orientation, particularly for cleaning, pumicing, painting or decorating the outer surface of an aircraft, an autonomous moving body with a special design is used.  This moving body comprises two attachment assemblies (10,12), each equipped with attachment members (30,48) which can be moved towards and away from the surface, and a tool holder ass-embly (14), said three assemblies being able to move with respect to one another in a given direction.  Control means supported by; the tool holder assembly (14) ensure both the advance at a constant speed of said assembly with respect to the attachment assembly (10,12) fixed to the surface and the advance in the same direction and at a higher speed of the other attachment assembly, the two attachment assemblies (10,12) being in turn fixed to the surface without stopping the tool holder assembly (14).

Title: Hydraulic coupling
Inventor: WILLIAMSON NIGEL D L
IPC: F16L15/04
Filed: 1989-01-27
Granted: 1993-06-29
Abstract: ABSTRACT       A fluid coupling assembly particularly adapted for connecting hydraulic conduits to the ports of a fluid manifold.  The coupling comprises a male member which is threadedly connected to the port and which includes tapered locking surfaces on the male and female members, respectively, that are in tight frictional engagement when the male member is threaded into the female member.  An O-ring is positioned in a pocket and disposed between the threads and the tapered locking surfaces to isolate the locking surfaces from hydraulic fluid, thereby ensuring a dry, frictional wedge lock.  The O-ring is of a size that permits it to move axially in the pocket.  In a modified embodiment of the coupling, there is provided an adjustable fitting which includes a lock nut having a skirt portion that is wedged into the tapered O-ring pocket.

Abstract: PROSTHETIC KNEE JOINT WITH IMPROVED     PATELLAR COMPONENT TRACKING                        Abstract A three-component knee joint prosthesis is disclosed including femoral, tibial and patellar components.  During flexion of the prosthetic knee, the patellar component, which has a convex bearing surface, cooperates with and is guided by a patellar track defined by the anterior plate portion, lateral condylar bearing portion and medial condylar bearing portion of the femoral component and a web portion joining the two femoral condylar bearing portions.  The inner regions of the two femoral condylar bearing portions are steeply sloped towards the web portion to permit the patellar component to "ride deeply" upon the femoral component at high degrees of flexion, thereby reducing quadriceps tension and expanding the permissible range of motion in flexion.

Title: Shear mode transducer for ink jet systems
Inventor: FISCHBECK KENNETH H
IPC: G01D15/16
Filed: 1989-02-27
Granted: 1992-12-29
Abstract: Shear Mode Transducer for Ink Jet Systems Abstract In the shear mode piezoelectric transducer for an ink jet system described in the specification, a piezoelectric plate (17) is polarized parallel to the plane of the plate and in directions extending away from the center of the pressure chamber with which the transducer is used, and electrodes (20,21) mounted on opposite surfaces of the plate impose electric fields orthogonal to the direction of polarization.  The resulting shear motion of the transducer decreases the volume of the pressure chamber (11), ejecting a drop of ink from an orifice (15) communicating with the pressure chamber.  The piezoelectric plate (17) used in the transducer is prepared by imposing electric fields within the plate in the direction parallel to the plane of the plate between electrodes mounted on opposite sides of the plate in the central region of the pressure chamber and electrodes mounted on oppo-site sides of the plate in the peripheral regions of the pressure chamber.

Abstract: ABSTRACT OF THE DISCLOSURE A damaged hydrant casing which has an integral barrel extending below ground level is repaired without excavation. A support structure defining a horizontal work surface is clamped to the hydrant barrel. A powered groove-forming tool is supported from the work surface with a mechanical spacer and moved about the barrel to form a circumferential groove. A powered cutting tool is then supported from the work surface with another mechanical spacer and moved about the barrel to cut the barrel circumferentially above the groove. An upper defective portion of the hydrant casing is removed and only a stub portion of the barrel remains above ground. A split flange with a frangible inner lip is secured to the stub portion of the barrel with the lip seated in the circumferential groove. A shorter hydrant casing having a lower complementary flange is then seated on the split flange, and the two flanges are secured to one another with bolts. The support member is then released and removed.
