Patent CA-2187916-A1 (CA)
Title: Portable water purification apparatus
Inventor: GREENE RALPH G
IPC: C02F1/04
Filed: 1995-10-24
Abstract: A water purification apparatus (10) positionable on an existing dispenser (158) has a valve control member (154) positionable in the water plenum of the dispenser to control release of purified water from the apparatus to the dispenser. A feedwater tank (26) receives supply water which is fed to a water level control tank (52) to maintain the water level in the boiler (60) of the apparatus above the heating element. The control tank includes a partition separating a main reservoir (68) from a de-foamer control chamber (70) within which anti-foaming agent may be added. Water exiting the reservoir enters the boiler where it evaporates and the vapors enter a condenser (114) where the vapor condenses into water. The condenser (114) is coiled into a number of convolutions about a central opening (115) and has external heat exchanger fins (116). An end cap assembly (118, 126, 130, 134, 136)closes the central opening (124) except for a small portion through which air is blown by a fan so that substantially all of the air flows over the fins. The boiler is a cylindrical container having a peripheral lip (96) about an open end on which a lid (94) having a steam outlet tube (100) is positioned. The lid is secured in sealing relationship with the lip by a coil spring (104) urged by a bar (106) having clamps (108) which grasp the peripheral lip (96).

Title: Endoscopic ligating instrument
Inventor: AHMED MUNIR
IPC: A61B17/00
Filed: 1995-01-31
Abstract: An endoscopic instrument for ligating multiple lesions within a hollow body organ. A plurality of cords (103) are laid over the tube (101) to extend longitudinally thereon and be folded over the distal end of the tube. A plurality of elastic rings (50) are mounted on the tube (101) in stretched condition and overlaying the cords (103). The segment of each cord (103) between each pair of adjacent rings (50) is in slack condition and of a length which equals or exceeds the distance of the tube's distal end to the furthest ring of the pair. By a trip cord (105) threaded through a working channel (19) of the endoscope and connected to the cords (103), a pull can be exerted thereon to simultaneously retract the cords (103) and dislodge each of the rings in controlled stepped sequence in a procedure wherein only one elastic ring at a time moves over the tube in the process of its dislodgement to ligate a lesion which has been suctioned part way into the tube (101).

Inventor: SASAKI MASANORI
IPC: B67C3/26
Filed: 1995-09-26
Abstract: Plaque (10) à ajutages pour apport de liquide, comportant une plaque pourvue d'une série d'orifices traversants (11). On utilise cette plaque (10) en la fixant à l'ouverture de l'extrémité inférieure d'une conduite d'apport de liquide (67). Toute la sortie du liquide emplissant la conduite d'apport (67) est rendue impossible en raison de la tension de surface du liquide dans les orifices (11) de la plaque à ajutages (10). Sur la surface périphérique interne (13) de chaque orifice traversant (11) des saillies (15) sont ménagées. Ces saillies sont disposées dans le sens périphérique de telle sorte que le diamètre interne de l'orifice traversant (11) se trouve réduit. Du fait de la forme de la section transversale de cet orifice (11), toute fuite de liquide hors de cet orifice (11) peut être prévenue de manière efficace. Même lorsque les orifices (51) sont réalisés de telle sorte que leur section transversale se présente sous la forme d'une fente allongée, toute fuite de liquide par ces orifices peut également être empêchée de manière efficace.

Abstract: A dragline bucket having first and second contoured dumping rails respectively supported on first and second spaced apart opposite sidewalls and a rear wall.  Each dumping rail extends from above the sidewall on which it is supported to the rear wall on which it is also supported.  Rollers are connected to a hoist rope and support the bucket in a suspended manner.  The rollers engage the first and second dumping rails and are movable along the dumping rails from a forward position in which an open end of the bucket faces substantially horizontally, to a rearward position in which the open end of the bucket faces downwardly to dump material in it.  The dumping rails adjacent to the rear wall of the bucket are preferably spaced from the rear wall of the bucket.          The rollers include first and second rollers  which respectively engage the undersides of the first and second dumping rails.  Each dumping rail may be angled relative to the sidewall on which it is supported in an upward direction toward the opposite sidewall.  The first and second rollers are separately connected to first and second hoist chains which extend from above the bucket at an angle toward the dumping rails and the first and second rollers each have an axis which is substantially perpendicular to the lengths of the respective first and second hoist chains.  Each of the dumping rails is spaced from the rear of the bucket.

Title: Press drive with oil shear clutch/brake drives
Inventor: SOMMER GORDON MAURICE
IPC: F16D55/00
Filed: 1997-06-09
Abstract: A drive unit for driving a press uses a hydraulically actuated oil shear brake unit located on one side of a flywheel and a hydraulically actuated oil shear clutch unit located on the opposite side of the flywheel. The actuating assemblies for the oil shear brake unit and the oil shear clutch unit are supplied as complete assemblies which are secured to the brake housing and clutch housing, respectively, at the time of assembly of the units to the press. The actuation of the clutch unit and the brake unit occur simultaneously and from the same hydraulic pressure source such that the overlap between the two units is controllable from no overlap to a specified amount of overlap where the brake unit is applied simultaneously with the engagement of the clutch for a specified amount of time. The stroke acquired by the brake and clutch actuating assemblies can each be selected at the time of assembly by selecting the appropriate width for a plurality of spacers.

Inventor: FRASER JAMES M III
IPC: E21B33/05
Filed: 1997-07-23
Abstract: An apparatus and method are disclosed for pumping segregated through atubular member, such as is required when cementing a liner into a well bore.  A liner wiper plug has an internal bore formed therethrough, with a flapper valve mounted in the liner wiper plug.  The flapper valve can pivot to an open position to allow fluid flow through the wiper plug, and the flapper valve can pivot to a closed position to prevent fluid flow through the wiper plug.  A work string, or a stinger attached to a work string, can be positioned within the internal bore to the wiper plug, holding the flapper valve in the open position.  The wiper plug can be run into the well on the work string, with the flapper valve held open, and with flow of a first fluid in progress.  The wiper plug can be releasably supported from the liner.  The work string is withdrawn from the wiper plug to allow the flapper valve to close.  Pumping a second fluidthrough the work string to apply fluid pressure to the wiper plug will then release the wiper plug from the liner and force the wiper plug to pass through the liner as desired, segregating the two fluids.
