Patent number: 4546499Abstract: A graft is used to supply blood to one or more coronary artery branches. The graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction located remote from the inlet end of the tubular body. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.Type: GrantFiled: December 13, 1982Date of Patent: October 15, 1985Assignee: Possis Medical, Inc.Inventors: Zinon C.

Patent number: 4546542Abstract: A method of making a planar fork contact initially having plural tines with respective coplanar surfaces and gold inlay material integral with such coplanar surfaces, to bring them into substantially confronting relation with each other within the plane of the contact. Other steps include setting the twist to maintain such inlay containing areas in such confronting relation, controlling such twisting and the location of the respective twists for contact uniformity, and using cut-away tabs on the tines to facilitate twisting. The invention also relates to an apparatus for making such planar fork contacts, especially by utilizing the method of the invention.Type: GrantFiled: October 8, 1981Date of Patent: October 15, 1985Assignee: Symbex CorporationInventor: Ralph A.

Patent number: 4546543Abstract: Projecting leads (28) on a support container (16) for a mini-oscillator assembly (14) initially are straightened in perpendicular directions in a lead-straightening mechanism (48). The straightened leads (28) then are reverse-bent in a bending mechanism (50), utilizing contact pads (26) on a substrate (22) of the mini-oscillator assembly (14) as anvils, so that the lead outer end portions retain the assembly adjacent the support container and so that the lead outer end portions can be bonded to the contact pads. Seating of the lead outer end portions (59) firmly on the contact pads (26) is insured by a lead-seating mechanism 60. The lead-bending mechanism 50 also applies pressure to the substrate (22) in the lead-bending operation to cause uniform spreading of an adhesive material (33) between the substrate and the support container (26).Type: GrantFiled: December 19, 1983Date of Patent: October 15, 1985Assignee: AT&T Technologies, Inc.Inventor: John B.

Patent number: 4546547Abstract: A checking and aligning stand for measuring and aligning structure sections of the strand guide of a continuous casting plant includes measuring surfaces to determine the mounting position of the structure section. In order to be able to effect a quick check of the mounting position of curved structure sections of a bow-type continuous casting plant without impeding the casting operation during this adjustment work, at least two pairs of measuring surfaces arranged at an angle to each other, preferably at 90.degree., to determine the roller-way coordinates relative to the position-defining supporting surfaces of the structure section are provided on the checking stand.Type: GrantFiled: August 19, 1982Date of Patent: October 15, 1985Assignee: Voest-Alpine AktiengesellschaftInventors: Werner Scheurecker, Alois Scheinecker, Johannes Cordella, Kurt Engel
