Abstract: Apparatus and directed to improved gating for the investment casting of metal wood golf club heads.

Abstract: A method for direct printing of micro-optical components onto optical substrates or active devices to create optical circuit elements as well as micro-optical components and systems, such as plano-convex circular, cylindrical or square lenslets, anamorphic lenslets, waveguides, couplers, mixers and switches and monolithic lenses deposited directly onto optical components such as diode lasers and optical fibers. The method provides a means for precisely depositing a wide range of materials in a wide variety of shapes for fabricating a full range of passive and active micro-optic devices.

Abstract: A pulsation nozzle is adapted for insertion in a drill bit such as a single body or tri-cone bit, for delivery of a pulsed jet of thixotropic drilling fluid during drilling operations. The nozzle defines an inlet orifice (31) communicating with an internal cavity (32) and an outlet orifice (33), the dimensions of which are chosen in such a way as to induce the cyclical propagation of disturbances in a shear boundary defined between fluid passing directly through the nozzle and fluid which is momentarily trapped in the cavity, thereby inducing a self-excited oscillating flow of said fluid within the nozzle, and a rapid pulsing flow emitting from the nozzle.

Abstract: The apparatus includes a base engaged with a support arm, which support arm is adapted to receive a tubing clip. The tubing clip includes a slot that is adapted to receive intravenous tubing or a central venous catheter and to retain the tubing in a secure manner so as to support in a stationary manner an injection cap associated with the tubing or catheter.

Abstract: A disposable, one-piece, bristleless can cleaning device including a body, cyclindrical in cross-section with a circular base wall and integral annular, concentric outer and inner side walls, the outer wall formed along the periphery of the base wall and the inner wall being located inwardly from the outer wall, the two walls forming a cavity for receiving the upper end portion of a can. The can cleaning device is made of a sturdy, resilient, absorbent material that has been treated with a sanitizing substance. The side wall and the inner wall both extend downwardly frown the base of the device, the side wall extending downwardly over the outer upper portion of the can exterior and the inner wall, having a diameter smaller than the side wall, extending downwardly into the groove located on the upper end portion of a beverage can.
