Patent CA-2123796-A1 (CA)
Inventor: WOOD ERIC
IPC: F16L55/16
Filed: 1993-02-12
Abstract: The present invention provides that an assembly can be fed into a pipeline or passageway to which a lining tube is to be applied. The lining is impregnated with curable synthetic resin, and surrounds an inflatable bladder, the bladder in turn sur-rounding a cure pipe through which medium flowing in the pipeline or passageway can pass during the lining operation. The core pipe is of sufficiently rigid nature to withstand an inflation pressure to move the lining tube onto the pipeline or passageway sur-face by inflation of the bladder, but yet is sufficiently flexible and bendable so as to bend enabling in to follow curves and falls in the pipeline or passageway into which it is inserted. Specifically the tube should be sufficiently bendable to enable the assembly to be fod down a manhole and into the underground pipeline or passageway.

Abstract: HIGH DENSITY FIBER OPTIC CONNECTOR                 ABSTRACT OF THE DISCLOSURE A fiber optic connector is described, which has a retention clip (100, Fig. 4) that is part of the terminus so the clip is removed with the terminus from a connector housing, to enable replacement of a broken clip as well as to provide a more compact and low cost connector. The clip has a rear end (102) forming a ring that slides along the termir us body, and has a plurality of tines (104 - 107) that extend forwardly and radially outwardly. The free forward end of each tine has a rearwardly-facing clip shoulder (112) which abuts a forwardly-facing housing shoulder (114) so the clip cannot be removed in a rearward direction until the tines are deflected together. The front ends of the tines abut the rear end (92) of a spring that lies around the terminus body. The termini ofthe plug and receptacle connectors are identical except that one of the connectors (14, Fig. 5) uses a spacer (140) in place of a helical spring.

Title: Surface and near surface hardened medical implants
Inventor: DAVIDSON JAMES A
IPC: A61L27/00
Filed: 1994-08-16
Abstract: Surface and near surface hardened medical implants are provided. These implants are fabricated from titanium alloys that contain an amount of zirconium sufficient to permit the formation of a significant amount of zirconium oxide at the surface of the implant to cause surface hardening. Further, the zirconium-containing titanium alloy implants are characterized in having an alloy core with an oxygen-rich layer surrounding the core, and a surface layer, overlying the oxygen-rich layer, including mixed oxides of the metals present in the alloy. A zirconium-rich interface may sometimes be present between the oxygen-rich layer and the mixed-oxide surface layer. The method of producing these surface hardened implants includes the steps of heating the implant in an oxygen containing environment at a temperature sufficient to allow oxygen to diffuse to and react with the implant surface and near surface.

Inventor: HIASA MASAMI
IPC: C02F1/00
Filed: 1994-03-30
Abstract: A process and device for purifying water of the type wherein activated carbon is subjected to regeneration.  Tap water is contacted with activated carbon fibers characterized by a narrow micropore distribution and a high adsorption speed, to eliminate by adsorption residual chlorine, harmful trihalomethane compounds and smelly substances such as 2-methylisoborneol and geosmin that are present in tap water.  Activated carbon fibers having a modal micropore diameter of about 1.8-3.0 nm, preferably, 2.0-2.7 nm, are used to cause the large-molecular-weight smelly substances to be intensively and selectively adsorbed by the activated carbon fibers.  In non-use, the activated carbon fibers are occasionally heated at a temperature of 100-120°C whereby trihalomethane compounds adsorbed in the activated carbon fibers are desorbed so that the adsorption capability of activated carbon fibers with respect to trihalomethanes is restored. Accordingly, trihalomethanes as well as smelly substances can be eliminated for a long period without requiring replacement of activated carbon fiber cartridge, while using a limited amount of activated carbon fibers.

IPC: B24C7/00
Filed: 1994-12-30
Abstract: A media control valve used to meter and dispense an amount of abrasive media from a supply pot to a compressed air line for blast cleaning comprises a vertical media passage communicating with the supply pot and an air flow tube and a restricting orifice in the media passage to meter the amount of abrasive media flowing therethrough the vertical passage into the air flow tube, the media passage downstream of the orifice converging into a slot-shaped outlet into the air flow tube wherein the length of the outlet is directed along the direction of air flow through the air flow tube so as to reduce the perimeter of the outlet placed perpendicular to air flow and consequently reduce turbulence as the air passes across the outlet.  The media valve is particularly useful in metering and dispensing sodium bicarbonate media from a supply pot to the air conveying line by means of differential pressure across the orifice.

Title: Multi-cell pool, lagoon and basin thermocover
Inventor: KOR BOUKO J
IPC: E04H4/08
Filed: 1995-12-22
Abstract: A continuous cover for open bodies of liquid has three or four modular elements - cell, float, cap, and anchor float. The cell of the cover has a central ovoidal or spheroidal cupola to provide strength, in a hexagonal horizontal edge wall surround. The edge wall has two levels each of three adjacent sides, so one can rest on the other, the cells can also be stacked on top of each other. The lower hexagonal wall incorporates two pins in its outer sides to engage apertures in upper hexagonal wall outer sides of neighboring cells. Floats have upper threaded protrusions which engage apertures in the middle sides of upper and lower walls, secured in place by threaded caps engaging the threaded protrusions. The floats also have lower wells to receive the upper protrusions so the floats are stackable. Anchor floats which are deeper and have a sealable side aperture to admit liquid, may also be used to weight or ballast the cover. The cover in place provides a substantially gapless insulating layer with a dead space over the liquid.
