Abstract: A tubular charge holder assembly for a perforating gun made of a tube having a plurality of pairs of diametrically opposed openings. The pairs of openings are formed over a length of the tube, wherein the each pair has a larger and a smaller opening. A shaped charge is located within the pairs of openings in the tubular charge holder so that at least a portion of the rim of a front face of the shaped charge extends out of the larger opening and at least a portion of a rear face of the shaped charge extends out from the smaller opening of the tube. A detonating cord is helically wrapped around the outside surface of the tube such that the detonating cord is positioned so that the cord is proximate to the rear surface of each of the shaped charges installed within the tube. A substantially semi-circular clip is positioned on the outside surface of the tube proximate each of the shaped charges. Each clip includes first hook on a first end and a second hook on a second end on the front of the clip for engaging at least two portions of the rim surrounding the front face of the shaped charges.      On a back of the clip, the clip has a retainer, such as a U-shaped portion or snap device to secure the detonating cord proximate to the rear surface of the shaped charge.      The retainer may be perpendicular to a longitudinal axis of the clip or may be angled or offset with respect to the longitudinal axis of the clip to accommodate the helically wrapped detonating cord. The clip may be a wire, a pair of wires, a band, a perforated band having a adjuster or other suitable configurations.

Abstract: Retroreflective sheeting includes a body layer (12) having a structured surface with recessed faces (22) and top surfaces (20), the recessed faces forming cube corner cavities. The recessed faces have a high specular reflectivity, while the top surfaces have a low specular reflectivity. In some embodiments, a substantially continuous film of reflective material covers the structured surface, and a masking substance is provided over the reflective material at the top surfaces. Alternatively, the top surfaces are given a non-smooth surface finish so that the film of reflective material on those portions has a diffuse reflectivity. In other embodiments the film of reflective material is discontinuous, disposed selectively on the recessed faces and not on the top surfaces. A cover layer (16) is also provided, and can bond at least to the top surfaces. Keeping the top surfaces substantially free of reflective material inhibits corrosion and can enhance the bond integrity. The top surfaces are preferably flat, and diffusely reflective to enhance the daytime whiteness of the sheeting.

Title: Ureteral access sheath
Inventor: CLAYMAN RALPH V
IPC: A61M25/06
Filed: 2000-04-26
Abstract: A ureteral access sheath (10) adapted for insertion into a urethra includes an elongate tube (14) extending between a proximal end, and a distal end. A handle (23) assembly is disposed at the proximal end, and includes enlarged portions which inhibit migration of the sheath into the urethra. The enlarged portion is shaped like the bell of a horn with a concave, distally facing outer surface (41), and a convex, proximally facing inner surface. The inner surface functions as a funnel while the outer surface is sized, and configured to receive adjacent fingers of a user's hand held in its natural position. In an associated method, this shape of the handle assembly facilitates maintaining the sheath (10) in a stationary position during insertion, and removal of instrumentation. The handle assembly can be movable on the tube to facilitate variation of the sheath link in situ.
