Abstract: OVEN LINER AND RACK DESIGN     ABSTRACT OF THE DISCLOSURE            The specification discloses an oven liner having canted ribs for supporting an oven rack.  The parallel elongated ribs are defined by converging canted upper and lower surfaces extending from the side walls of the oven liner into the oven cavity.  A series of nodes are spaced along the upper surface of each rib to support an oven rack.  A shoe protrudes from the lower surface of the ribs near the forward end of the oven cavity, the shoe engaging a boss formed on guide rails on two sides of the oven rack to prevent the rack from being completely withdrawn from the oven.  The oven rack is a mesh formed of parallel bar members having guide rails disposed perpendicular to the plane of the mesh along two sides thereof.  Supporting surfaces are provided at an angIe to the rails so that the rack maybe slidably supported at an angle to the horizontal by the nodes formed on the upper surface of the ribs.  A boss projecting from the lower rear portion of the guide rails engages the shoe on the lower rib surface to prevent the rack from being completely withdrawn from the oven cavity.

Abstract: "METHOD OF COLD FORMING"                ABSTRACT OF THE DISCLOSURE     The invention relates to the cold extrusion of a part having a polygonal interior and a cylindrical exterior.          Instead of the usual process of forcing a polygonal punch into a billet in a single extrusion step, the new method employs a plurality of extrusion steps, first forming a lobed preparatory blank and then in a second extrusion step providing a punch and die combination whereby the external lobes of the intermediate part are farced radially inwardly.          In the second extrusion step a polygonal punch is used to provide the proper polygonal interior surface.  A cooperating die is provided with an upper lobed cavity for receiving the lobed preparatory blank and this died is oriented with respect to the polygonal punch so that the interior lobes of the die are exactly opposite the flats of the polygonal punch.  Below the upper lobed cavity of the die is a cylindrical cavity of smaller diameter and between the two is a conical surface which directs the metal of the lobes inwardly into the die cavity opposite the flats of the polygon.  The preferred polygon is a hexagon.

Abstract: ABSTRACT        The present invention relates to a syringe comprising a rotationally symmetrical barrel, a plunger, a cylindrical stopper and a needle holder.  The barrel is in a shape of a hollow cylinder with an open front end.  The plunger is sealably disposed within the barrel and is movable with respect thereto, the cylindrical stopper has an outside diameter which is slightly larger than an inside diameter of the barrel and includes means which seal the front end of the barrel.  The needle holder includes a collar which is attached in sealing relationship to the front end of the barrel, a neck for sealable attachment to an injection needle, the neck having a rotationally symmetric rear face which includes an aperture which functions to conduct fluid to the needle, and a tubular section having a rear end which is sealably connected to the collar and a front end which is sealable connected to the neck; wherein inner walls of the tubular section and the rear face of the neck define one or more slots which extend from the rear end of the tubular section to the aperture.  The space bounded by inner walls of the tubular section and the rear face of the neck, apart from the slots, is longer than the stopper and has the same rotational symmetry and approximately the same diameter as the outer diameter of the stopper, so that the stopper can substantially fill the space but does not cover the ends of the slots at the rear end of the tubular section.

Abstract: ABSTRACT OF THE DISCLOSURE          A plurality of organizers each formed with an arcuate support member upon which a selected number of suture holding devices are positioned in spaced relationship one to the other, are each designed to be disposed proximate an area of a body upon which surgery is to be performed to facilitate speedy and orderly control of interrupted sutures and needles utilized during the surgical procedure.  Each holding device includes a pair of spaced wall members and a resilient holding member disposed in compression therebetween in such a manner that sutures can be releasably held between the resilient member and the adjacent wall member surface.  Additional valuable time for surgical procedures involving insertion of artificial heart valves can be saved by utilizing a heart valve holder having a plurality of circumferentially spaced legs, to which an artificial heart valve can be releaseably held by sutures. The legs which depend from an internally threaded holder formed for co-action with a rod slidably positioned in a holding disk which carries spring clips about its circum-ferential edge for releaseable coaction with the sutures utilized to secure the valve in place.

Blankenhorn Title:  IMAGE AVERAGING FOR ANGIOGRAPHY BY REGISTRATION         AND COMBINATION OF SERIAL IMAGES                      ABSTRACT OF THE DISCLOSURE          A method and apparatus for angiography in which information contained within multiple serial images of contrast medium flowing through a blood vessel is combined to form a single image having improved vessel edge delineation.          More specifically, a method is disclosed whereby a contrast medium opaque to X-rays is injected into a blood vessel distant from an artery section of interest, preferably injected into a vein, whereby the contrast medium is mixed with blood prior to its passing through the artery section.          Multiple X-ray images are obtained as the contrast medium and blood mixture flows through the artery section.  These multiple images are registered with respect to each other according to a landmark contained within the patient, the landmark having a predetermined relationship to the vessel of interest.  The landmark could be a bone, catheter or any other material opaque to X-rays.  Density measurements are made with respect to each corresponding image segment or element of the multiple images and are combined to synthesize a composite image. The synthesized image has an edge un-certainty equal to that of one of the individual images divided by the square root of the total number of images utilized.

Abstract: ABSTRACT OF THE DISCLOSURE     Bottle-shaped containers of biaxially-oriented blow-molded plastic material are introduced into the space formed between the helical blade continuously rotated and the backup plate of a screw conveyor, and are conveyed in one direction to next conveyor by the rotation of the helical blade of the screw conveyor.  The bottle-shaped containers are stood by at the end of the conveyor.  When a predetermined number of bottle-shaped containers thus conveyed are aligned in predetermined longitud-inal and lateral array, they are simultaneously held by a container group holding mechanism utilizing negative pressure, and are then raised from the standby position.  The containers thus raised are lowered directly into a corrugated fiberboard box designed to accommodate the aligned container group, by releasing the pressure in the container group holding mechanism.
