Patent number: 4693993Abstract: The substitution of the L-Pro at the 7-position of the peptide hormone bradykinin or other substituted analogs of bradykinin with an aromatic amino acid or the D-configuration converts bradykinin agonists into a bradykinin antagonist. The invention further includes additional modifications at other positions within the novel 7-position modified bradykinin antagonists which increase enzyme resistance, antagonist potency and/or specificity of the new bradykinin antagonists. The analogs produced are useful in treating conditions and diseases of the mammal and human body in which an excess of bradykinin or related kinins are produced or injected as by bites into the body.Type: GrantFiled: June 13, 1985Date of Patent: September 15, 1987Inventors: John M. Stewart, Raymond J. Vavrek

Patent number: 4657092Abstract: A transformable circulation tool for reversing the path of drilling fluid at the drill bit without removing the drill string from the borehole annulus is provided by a substantially hollow body having a chamber with external ports disposed between a section of the body having a through passage and a by-pass passage in combination with a diverter mounted on a telescoping member having means for engaging the body during drilling and disengaging the body for rotation of the diverter with respect to each of the passages. A seal is rotatably mounted to the substantially hollow body between the ports to divide the well borehole into an upper conventional flow portion and a lower portion where the flow of the drilling fluid can be reversed upon command from the surface.Type: GrantFiled: July 17, 1985Date of Patent: April 14, 1987Assignee: J & F Oil Tools, Inc.Inventor: Robert L. Franks, Jr.

Patent number: 4627417Abstract: The invention relates to a steam pressure cooker, which essentially consists of a lower pot and a cover unit sealing the lower pot. The lower pot has a smooth circular pot rim. The cover unit consists of a lower lid and an upper lid. The latter is designed as a sealing element, which engages the lower part of the pot rim by the flanges. As an improvement of this type of pressure cooker, it is proposed that the upper lid contain two half-lids, and that each half-lid be able to rotate about its own axis of rotation essentially parallel to the central axis of the pot (geometrically vertical) relative to the lower lid and lower pot, and further, that the axes of rotation lie eccentric to the pot's central axis and diametrically opposite each other with respect to this axis swivel mechanism rotatably supported concentrically on the lower lid.Type: GrantFiled: August 20, 1984Date of Patent: December 9, 1986Inventors: Reinhard von der Becke, Horst Schultz

Patent number: 4609144Abstract: A universal railroad tie cover of a substantially rectangular configuration is provided which is composed of an elastomer material having one or more openings for receiving one or more elastomer pads for increasing the resiliency of rail fastening systems in railroad track beds with and without ballast to prolong the service life of timber and concrete railroad ties. The universal railroad tie cover has a center section with at least one opening and two side portions for receiving interchangeable specially designed pads some of which may be designed for a particular system and/or for wood or concrete ties to prolong operational life by increasing the resiliency of the rail fastening system. The universal railroad tie cover and particular pads are designed to be manufactured and shipped in a flat configuration which can be cut and installed as a three dimensional cover at the work site to accommodate varying lengths of timber and concrete ties as may be required in special track work.Type: GrantFiled: April 27, 1984Date of Patent: September 2, 1986Assignee: STEDEF S.A.Inventor: John L. Harmsen
