Abstract: A stick launcher and method for launching soap sticks into a gas or oil well. The stick launcher comprises a containment vessel adapted to house the soap sticks, the containment vessel comprising a contiguous wall and a top and a bottom. A turret-style separator is positioned within the containment vessel, the separator comprising blades, and adapted to contain the soap sticks between the blades of the turret-styled separator and the contiguous wall of the containment vessel. A ball valve is positioned adjacent the bottom of the containment vessel, the ball valve, when in open position, adapted to be in fluid communication with a well bore and the containment vessel. A rotating assembly, when set in motion by an actuator, is used to rotate the separator and simultaneously open or close the ball valve. The rotating assembly comprises a ratchet mechanism and an actuator plate that, while acting on the separator to advance a soap stick into position in the passage way, opens and closes the ball valve so that the containment vessel and soap sticks have minimal contact with the moisture laden fluids of the well bore.

Title: Vaginal speculum with seal
Inventor: VAN DER WEEGEN CLEMENS
IPC: A61B1/303
Filed: 2000-03-30
Granted: 2008-08-19
Abstract: A vaginal speculum of the kind including a tubular probe (6) for penetrating the vagina wherein the probe is encircled by an annular sealing element (13), in the form of a thick walled, domed shell of polyethylene foam, spaced from the leading end of the probe and which seals only against a circumferential zone of the internal tissue defining th e vaginal orifice. The external surface of the sealing element is shaped as a surface of revolution wherein the diameter of the sealing surfac e increases progressively with axial distance from the leading end of the sealing element and wherein the rate of increase diminishes progressively with said axial distance. The seal therefore provides a low-pressure seal over a limited range of depths of penetration of the probe into the vagina and over a range of angular alignments of the probe.

Title: Electrochemical cover for inhibiting diffusion/infiltration of oxygen into reactive sulphide materials
Inventor: BROUSSEAU REJEAN JOSEPH HENRI
IPC: B09B1/00
Filed: 2000-11-24
Granted: 2004-11-02
Abstract: Acidity in water leaching from a mass of sulphide tailings is prevented by de-oxygenating the water prior to entering the mass. A cover comprising an electrolytic cell, either galvanic or impressed-current, gives rise to a cathode reaction in which the redox voltage of the water drops to 003 volts or less. The cover can be thinner, and much less expensive, than an equally-effective non-reactive cover. The electrolyte is water contained in water-retaining soil, or a depth of water, lying over the cathode. The cathode is steel mesh, or a layer of graphite, spread over the whole mass of tailings.
