Patent CA-2142955-A1 (CA)
Title: Apparatus and method for testing motor operated valves
Inventor: ROBERTS JEFFREY J
IPC: F16K37/00
Filed: 1995-02-20
Abstract: An apparatus, for testing a spring pack of a valve operator, includes a hollow housing with a coupling for attaching to the valve operator.  A slider is received within the housing and moves therein when driven by a bolt that extends through a threaded aperture in the housing.  A load sensor is attached to the slider and extends through the coupling and engages a valve operator component that is connected to the spring pack.  As a technician turns the bolt, the apparatus compresses the spring pack within the valve operator and the load sensor produces an electrical signal that indicates how much force is exerted by the spring pack.          At the same time, a transducer produces another electrical signal indicating the displacement of the spring pack.

Title: Regeneration of used cleaning solution
Inventor: TASTAYRE GILLES
IPC: C02F1/52
Filed: 1995-10-31
Abstract: A method is provided for regenerating spent cleaning solutions, whether they be alkaline, acidic, or neutral. The method involves the sequential steps of first preconditioning the spent solution. Then, an absorbent material is added to the preconditioned solution to provide an interactive solution. The precipitating of the undesirable materials from the interactive solution is accomplished by adding an anionic polymeric flocculating agent and a cationic polymeric flocculating agent thereto, in the following sequence of steps, namely (i) adding either the anionic polymeric flocculating agent or the cationic polymeric flocculating agent to the interactive solution to provide a reactive solution, (ii) thoroughly mixing the reactive solution, and (iii) adding the other of the cationic polymeric flocculating agent or the anionic polymeric flocculating agent, (respectively), thereby precipitating insoluble salts as large-sized and hard flocs. Finally, the solution containing the precipitated flocs is subjected to a solid/liquid separation. This regenerated solution is virtually indistinguishable from a fresh-made cleaning solution which is made from caustic and water, or acid and water.

Inventor: WRIGHT RAYMOND L
IPC: E21D20/02
Filed: 1996-01-19
Abstract: A reinforcing and support system and method of installation thereof including both a mechanical expansion anchor on the distal end of an elongated bolt and a resin grouting mix installed in a blind drill hole in a mine roof, or the like.  A pair of elongated leg members, fixed with respect to the shell, extend into the annular space surrounding the bolt below the shell for a distance about as great as the axial length of the shell.  Upon advance of the bolt, carrying the expansion anchor and leg members, into the drill hole to break a cartridge containing the initially flowable components of the grouting material, the bolt is rotated to effect expansion of the anchor and tensioning of the bolt. Mixing of the components in the annular space surrounding the bolt below the anchor as the bolt is rotated is enhanced by hydraulic turbulence produced by flow of the components about the leg members.  A support nut may be installed on the bolt below the anchor, and the leg members may be fixedly attached to one another near their terminal ends.

Abstract: A switched-inverter modulator (40) for use in driving a load (11) that comprisesmaster and slave high voltage power supplies (41, 42) for providing output pulses that directly drive the load (11). A synchronized pulse generator (45) provides pulse width timing and synchronized amplitude commands to the master power supply (41). The timing pulse instructs the power supplies (41, 42) when to initiate high voltage and for what time interval. The analog waveform instructs the master power supply (41) as to what high voltage level to obtain. The master power supply (41) may have multiple slaves (42) connected in parallel for additional current capacity. A low voltage DC capacitor bank (43) is connected in parallel with each of the power supplies (41, 42) to supplement energy storage. Isolation resistors (44) are coupled between outputs of the respective high voltage power supplies (41, 42) and the load (11) to minimize temporary shorts from ringing back into the power supplies (41, 42). A ramp generator (48) is provided for synchronizing timing pulses with corresponding amplitude commands, and for controlling the rise time of each power supply (41, 42). The switched-inverter modulator (40) is capable of varying pulse widths, pulse repetition frequencies, and amplitude output applied to the load (11), and complex radio frequency pulse trains may be created. The present invention provides for the smallest, lightest, and most versatile pulse modulator (40) available using current state-of-the-art technology to drive the load (11), and in particular a magnetron (11).
