Patent CA-2146040-A1 (CA)
Inventor: STEELE EDWARD A
IPC: H01H33/18
Filed: 1995-03-31
Abstract: A loadbreak switch is provided that utilizes a pivotally mounted movable jaw contact and a main stationary contact that is positioned in the middle of an arc runner. For operation at voltages 15kV and above, the switch utilizes a shunt contact that bridges the arc runner and that is above and coplanar with the main stationary contact. A magnetic field is developed by the current that flows through a coil of wire disposed around the arc runner.  This configuration when utilized in an environment of insulating gas, provides efficient extinguishing of arcs upon opening of the contacts. Further, the open jaw contact is easily visible to establish an open gap.

Title: Fluid holdup tool for deviated wells
Inventor: YOUNG ALLEN R
IPC: E21B47/10
Filed: 1995-04-19
Abstract: A production logging tool is provided for use within a well to determine fluid holdup of a multiphase fluid flow within the well.   The production logging tool includes a plurality of sensors secured within a plurality of arms which radially extend from a tool housing to points distal from the tool housing.  A plurality of sensors are included within the plurality of arms for detecting variations in fluid properties attributable to different flow constituents of the multiphase fluid flow along a path which circumscribes an exterior of the tool housing.  The plurality of arms are rotated about the tool housing for moving these sensors through the path in order to ensure that the volumetric proportions of the different flow constituents of the multiphase fluid flow are accurately detected in highly deviated and in horizontal wells.

Title: Methods for destroying ozone depleting substances
Inventor: MOUK ROBERT W
IPC: A62D3/38
Filed: 1995-02-22
Abstract: Ozone depleting fluorocarbon compounds are dehalogenated through more economic partial reduction reactions with solvated electrons formed from lower equivalents of reactive metals than previously employed. The partially reduced products are further dehalogenated with non-aqueous liquid nitrogen-containing bases, such as ammonia in the same reaction mixture, or alternatively, in an independent reaction by treating with ammonia or other base alone. In other embodiments, mixtures of fluorocarbon refrigerants including difficult to separate azeotropes of dichlorodifluoromethane contaminated with chlorodifluoromethane are reclaimed by treating only with weak non-aqueous nitrogen-containing bases to provide essentially chemically pure dichlorodifluoromethane refrigerant suitable for recycling/reuse.
Patent CA-2185377-A1 (CA)
Inventor: PLETT BENJAMIN
IPC: F15B15/20
Filed: 1996-09-12
Abstract: A grain elevator auger uses a hydraulic cylinder incorporating a checkvalve.  This checkvalve enables the volume of hydraulic fluid required to raise the elevator to be reduced to that required to replace the extended piston rod, instead of the full volume of the cylinder.  The necessary capacity of the tractor hydraulic system reservoirs which are used to raise the elevators are similarly lessened.  The checkvalve prevents hydraulic pressure retracting the piston, pressure is equalized on both sides of the cylinder piston, which then retracts slowly under the weight of the elevator, rather than rapidly under hydraulic pressure.

Title: Method of processing workpieces made of solid materials and device therefor
Inventor: BLIEDTNER JENS
IPC: B23K26/40
Filed: 1997-02-25
Abstract: The procedure is used for processing workpieces made of solid materials, especially glass preferably in tubular form for application or use in pharmacy, the chemical industry or veterinary medicine, by means of optical processing beams. For the purpose of cutting, drilling or controlled ablation of material use is made of an initial processing beam focused to the appropriate degree of sharpness and having a high energy density.  For shaping, remelting or heat treating use is made of a second processing beam with lower energy density, this second processing beam being less sharply focused or even divergent depending on the application.  The two processing beams can be adjusted via deflector units to strike the same or even different processing locations along parallel or converging paths.  To this end an initial interference modulator is provided for splitting into a transmitted and a reflected beam, the transmitted beam being reflected through reflecting mirrors arranged as prisms and traversing the first interference modulator once again in the opposite direction.  In addition, a second interference modulator is provided on to which the reflected beam is again reflected after passing through a telescope, while the twice transmitted beam is projected from the other side of the second interference modulator for renewed transmission.

Title: Horizontal mixer apparatus and method with improved shaft end seal structure
Inventor: MIDDENDORF MICHAEL J
IPC: B01F7/00
Filed: 1997-05-02
Abstract: A horizontal mixer for mixing and processing materials includes a horizontally disposed mixing chamber and an elongated rotatable mixing shaft extending longitudinally through the chamber. The drive apparatus is coupled lo a drive of the mixing shaft to rotate the shaft and mix material placed in the chamber. A stub end of the shaft has a bearing portion extending through an end wall of the chamber opposite the drive  end of the shaft. The bearing portion engages a sleeve bearing which is operable for rotatably supporting the stub end proximate the end wall opening.          A sealing shroud is coupled proximate the sleeve bearing and covers an outer portion of the shaft stub end. A static shroud seal is coupled with the sealing shroud at an interface between the shroud and the sleeve bearing. The static shroud is maintained out of direct contact with the rotatable shaft stub end. The sealing shroud and static shroud effectively isolate the shaft stub such that leakage between the chamber and the outside atmosphere is generally prevented.
