Title: Powder coatings
Inventor: SIMKIN BENJAMIN
IPC: C08L27/12
Filed: 1993-02-23
Granted: 2000-05-09
Abstract: A pigmented blend useful for powder coatings is provided comprised of PVDF resin, a thermoplastic acrylic resin, a pigment, and about 0.1 to 5 weight percent, based on the weight of the blend, of a VDF/TFE/HFP terpolymer. Other embodiments of the invention include a process for making a pigmented powder coating composition comprising the steps of blending the foregoing components, pelletizing, and cryogenically grinding, as well as a process of coating a substrate comprising the steps of applying the coating composition on the substrate, heating the composition above its melt temperature, and cooling of the substrate and applied coating composition. It has been found that incorporation of a small percentage of a VDF/TFE/HFP terpolymer into a blend of PVDF resin, compatible thermoplastic acrylic resin, and pigment results in a coating that has fewer defects (craters and pock marks) and a smoother appearance.

Granted: 2001-10-16
Abstract: A bent wire spring unit having a spaced pair of foot portions and a spring member extending upwardly from each foot portion. Each spring member is formed of a series of torsion bars and connector bars interconnected by bends in the spring wire. The spring members are connected at their upper ends by a locking member or portion having first and second pairs of bends in the spring wire and two locking bars extending from the second pair of bends. The locking bars are linear segments of wire angled downwardly such that they converge into a connecting bend. The locking bars and the connecting bend lie in a single plane and the distal ends of the locking bars and the connecting bend extend significantly below an uppermost torsion member of each spring member. A spring assembly is disclosed which includes the bent wire spring unit attached to a wire grid at its upper end and a base frame at its lower end. The spring unit is locked onto the wire grid by attaching the locking member to a wire in the wire grid such that the wire is contained in the second pair of bends.

Title: Method of analysing astigmatism and apparatus for performing corneal surgery
Inventor: ALPINS NOEL AMI
IPC: A61B3/107
Filed: 1993-03-04
Granted: 2003-09-23
Abstract: A method of analysing astigmatism is disclosed which enables surgeons to ascertain what surgery may be required subse-quent to initial surgery to achieve the preoperative aim of the initial surgery and to provide data amenable to statistical analysis which enables meaningful comparison of both multiple surgeries and techniques.  The method includes determining a preopera-tive astigmatism (1), defining an aimed astigmatism (2) and determining an achieved astigmatism (3) following initial surgery. The astigmatism values are initially determined in a 0 to 180° range and are doubled to convert them to a 360° range. An aimed induced astigmatism vector (AIA), a surgically induced astigmatism vector (SIA) and a difference vector are calculated and angle values are halved to return the angle values to a 0° to 180°  range. Magnitudes and angles of the vectors can be calculated to pro-vide astigmatism magnitude values and angle values for modifying parameters of future surgery for improved performance of fu-ture surgery and for statistical analysis. The method also provides a rationale for determining a treatment parameter when specta-cle and corneal astigmatism do not coincide.

Title: Methods of inserting tubing into live wells
Inventor: FUNK KELLY
IPC: E21B23/00
Filed: 1995-06-29
Granted: 1998-02-10
Abstract: A method of inserting tubing into a live well bore, includes attaching a resilient piston to a lower end of the tubing, lowering the piston into a passage at a well head to locate the piston in a position above a closure which prevents the escape of fluid from the well bore through the passage, sealing the passage around the tubing above the piston and opening a path of communication between the well bore below the closure and a portion of the passage above the piston to equalize the hydraulic pressure above the piston with that below the closure. The closure is then opened and fluid is pumped from a fluid reservoir into the passage above the piston to force the piston and the tubing downwardly in the well bore. Subsequently, the piston and the tubing are allowed to descend under gravity while fluid flows upwardly in the well bore past the piston by deformation of the piston by the pressure of the fluid.

Filed: 1996-02-12
Granted: 1999-05-11
Abstract: An illumination device illuminates a tap handle and an area proximate to a tap outlet.   The device illuminates a stream of fluid flowing from the tap outlet and the receptacle into which the fluid flows when the tap handle opens the tap to release the fluid.  The tap handle actuates a tilt switch adjacent to the tap handle.   The device illuminates a tap handle when there is no fluid flow.  Light from lamps contained within the device is communicated to the tap outlet and tap handle by separate fiber optic lines.  Light from the lamps is colored by a continuously rotating color wheel for aesthetic effects.  The device includes a capacitor for generating a time delay to prevent false control signals from being relayed to the lamps.

Abstract: A unique external injection port cover is provided that is open at one end, closed at the other end, and includes a set of spiraling screw threads on the inside. It is designed to be screwed into place over a specially adapted external injection port having its own corresponding screw threads. The inside of the closed end of the cover includes an inwardly pointing projection. A sponge is provided inside the open end, and a shatterable plastic capsule containing a combination of antiseptic, bactericidal and virucidal agents is provided between the sponge and the projection. A flexible O-ring seal is provided on the inside of the cover near the open end. When the present invention is screwed into place over an injection port, the O-ring first creates a seal over the end of the port. As the invention is tightened down, the pressure between the projection and the breakable capsule causes the capsule to rupture thereby releasing the antiseptic agents inside to be soaked up by the sponge. When completely tightened, the antiseptically treated sponge comes into contact with the latex membrane of the port, keeping it saturated, clean and aseptic until the cover is removed. The present injection port cover requires no maintenance when not in use resulting in decreased risk of infection and longer life of the injection port itself.
