Filed: 1991-12-09
Granted: 2000-02-29
Abstract: Surfaces of polymers, particularly polyesters, can be fluorinated by deposition of a fluorocarbon from solution. The fluoro-carbon may be an amorphous fluoropolymer, such as the copolymer of tetrafluoroethylene and bis-2,2-trifluoromethyl-4,5-difluoro-1, 2:dioxole sold under the trademark TEFLON AF R which is soluble in fluorinated alkanes and other fluorinated liquids such as those sold under the trademark FLUORINERT R.  Surface-fluorinated polyesters, particularly in knitted fabric form, are useful as vascular grafts: the fluorinated surface reduces thrombogenicity and complement activation. The disadvantages of known surface fluorination methods, such as the cold plasma or glow discharge process; are avoided.

Title: Unitized hydrant valve assembly
Inventor: KJAER NIELS A
IPC: F16K27/02
Filed: 1994-11-23
Granted: 1998-07-14
Abstract: A unitized, rubber coated valve body for a dry barrel fire hydrant.   The valve body is formed to have a hollow, tapered, substantially spherical, cast iron member having a hollow center, a threaded, upwardly facing hole for attachment to a control shaft or stem, a downwardly facing projection, and a rubber coating.  The unitized body eliminates labor of assembly during service and maintenance  operations.    The  rubber  coating  both  provides  a resilient valve face for effective sealing,  and protects metal parts of the valve from corrosion arising from contact with water.          The tapered body both distributes force evenly to the rubber valve face in the manner of a prior art metal disc, and enables water to flow therearound with minimized resistance, thereby maintaining head pressure at acceptable levels.  The novel valve body satisfies both objectives while minimizing weight and requiring minimal material for fabrication.  The body is formed with integral ears for slidably obstructing drain holes.  One or more of the ears has a stop pin mounted therethrough for preventing the passage of the valve body through the hydrant valve seat ring during reassembly after a field repair or maintenance operation.

Title: System and method for producing seasoned food products
Inventor: CENTER JOHN L
IPC: A23P1/08
Filed: 1993-12-10
Granted: 1998-12-29
Abstract: A system and apparatus for producing seasoned food products where seasoning is performed at individual packaging lines. The product is conveyed from the preparation area to a packaging area in an unseasoned condition. Upon reaching the packaging lines, which are disposed in packaging departments in the packaging area, the product can be selectively seasoned independent of other packaging lines. After seasoning, the product is packaged and prepared for delivery. At each packaging line, a volumetric feeder includes a feed head that cooperates with a tumbler having helical flights to produce continuous controlled product portions. A seasoning dispenser is positionable within the tumbler and can be adjusted to dispense a given weight of seasoning at a given rate, based on the amount of product passing through the tumbler, to obtain consistent seasoning levels and coverage. The ability to produce separate product types at each packaging line yields superior plant scheduling flexibility due to more packaging possibilities than a system which delivers already seasoned product to the packaging lines.

Granted: 1999-07-27
Abstract: A guidewire (16) for guiding and exchanging body insertable catheters includes a body insertable guide section (18) and an exchange section (20), both formed of flexible wire. In one embodiment, a pin connector (28) at the distal end of the exchange section (20) includes a truncated conical head (32), a shank (40), and a groove (44) between the head (32) and the shank (40). A socket connector (24) is attached to the proximal end of the guide section (18). Four indentations (58, 60, 62, 64) are formed in the socket connector (24), spaced apart angularly 90.degree. from one another. The maximum diameter of the conical head (32) is greater than the distance between opposed nodules (58, 60, 62, 64), but less than the inside diameter of the socket connector (24). Thus, the pin connector (28) is insertable into the socket connector (24) and temporarily elastically deforms the socket as the conical head (32) moves past the nodules (58, 60, 62, 64). Once the head (32) is beyond the nodules (58, 60, 62, 64), the nodules (58, 60, 62, 64) are captured within the groove (44), to allow rotation of the exchange section (20) relative to the guide section (18) while preventing any substantial axial relative movement of the sections (18, 20). The exchange section (20) can be disconnected from the guide section (18) by withdrawing the pin connector (28) proximally, again elastically deforming the socket (24) as the head (32) passes the nodules (58, 60, 62, 64).
