Title: Apparatus for measuring the voltage applied to a radiation source
Inventor: SHERIDAN TERRENCE E
IPC: H05G1/26
Filed: 1990-03-01
Granted: 1994-05-31
Abstract: (1) Abstract Apparatus is provided for use in detecting the input voltage applied to a radiation source operating at an unknown voltage within a given voltage range.  The apparatus includes a set of radiation absorbing filters including a first filter which includes a first chemical element and a second filter which includes a second chemical element. These elements are chosen so that the filters exhibit different radiation absorption characteristics within the given voltage range.  The filters are adapted to be positioned so that the first and second filters are irradiated by the radiation source with the radiation impinging upon a surface of each filter and partially absorbed thereby as it passes therethrough so as to exit therefrom as attenuated radiation.  A detector receives the attenuated radiation passed by the first and second filters and provides first and second signals having magnitudes which vary with the attenuated radiation respectively passed by the first and second filters.  A ratio is determined as to the magnitude of the first signal to that of the second signal with the magnitude of the ratio varying with that of the input voltage.  At least one of the first and second elements exhibits a known K absorption edge within the given voltage range.  Consequently as the input voltage is increased to exceed the known K absorption edge that chemical element exhibits a greater attenuation         (2) characteristic to extend the useful range of the relationship of the magnitude of the ratio and the input voltage.

Abstract: According to a method of detecting an acoustic signal, first and second sound receiving units are located at substantially the same position and are used to output signals having different target signal power to noise power ratios (S/N ratios).  When a difference between the powers of the signals output from the first and second sound receiving units or a ratio of the power of the signal from the first sound receiving unit to that from the second sound receiving unit in a given period falls within a predetermined range, reception of the target signal within the given period is discriminated.  The first sound receiving unit is an adaptive microphone array capable of controlling directivity characteristics in correspondence with a noise position.

Title: Process for recovery of gold from refractory ores
Inventor: THOMAS KENNETH G
IPC: C22B11/08
Filed: 1991-03-13
Granted: 2002-05-14
Abstract: The present invention is directed to an improvement in a process for the recovery of gold from refractory sulfidic auriferous ores which comprises oxidizing a slurry of ore with oxygen gas under pressure in the presence of sulfuric acid, neutralizing the oxidized slurry, cyanidizing the neutralized slurry to leach gold therefrom, and recovering gold from the resultant leachate. In accordance with the improved process, the oxidation of the ore slurry is carried out in a manner whereby after a startup phase during which oxidation is initiated, the amount of sulfuric acid added to the ore slurry is sufficient to insure the oxidation of that portion of the sulfide sulfur in the ore which will allow recovery, by cyanide leaching, of at least about 80% of the gold in the ore. The oxidized slurry can be neutralized without a washing operation.

Title: Filter units with end connectors
Inventor: REED CLAYTON L
IPC: B01D46/24
Filed: 1991-08-08
Granted: 1997-04-22
Abstract: An end connector system for connecting a plurality of filter units in series has first and second end connectors secured to the ends of filter units.  Each end connector has a base with a sealing surface and a connecting portion for engagement with the connecting portion of another end connector.  The connecting portions have overlapping surfaces that overlap in the radial direction of the bases when the connecting portions are engaged with one another.  A seal member is disposed between the first and second end connectors and is pressed into sealing contact with the sealing surfaces of the bases by a compression-generating member such as a tie rod.  When the sealing surfaces are in sealing contact with the seal member, the overlapping surfaces of the connecting portions are separated from one another.  As a result, all forces for producing a liquid-tight seal between the end connectors are generated by the compression-generating member and not by the end connectors themselves.

Title: Rotor placer for progressive cavity pump
Inventor: WEBER JAMES L
IPC: F04C11/00
Filed: 1991-08-19
Granted: 1994-03-29
Abstract: ABSTRACT A progressive cavity pump is used as part of the production string in an oil well. A pump stator is coupled to the production tubing string, while the rotor is driven by a sucker rod. To ensure proper placement of the rotor in the stator, the rotor is driven by a drive shaft with two universal joints with the upper end of the drive shaft held in position by a thrust bearing on the drive shaft and engaging a bearing seat connected to the production tubing. This ensures proper vertical placement of rotor in the stator. It also prevents eccentric motion of the upper end of the drive shaft, so that the sucker rod is no longer subject to whipping action that may damage the production tubing and the sucker rod string.

Title: Switch actuator
Inventor: SCHAFFER JOHN S
IPC: H01H3/00
Filed: 1991-10-22
Granted: 2002-12-24
Abstract: A switch actuator includes an operator plate which provides a structure for mounting the actuator and for supporting the remaining parts. An operator shaft receives torque from an operating handle and via mechanical coupling, transmits torque to a torque plate subassembly. The torque plate compresses a torsion spring which provides temporary energy storage for the switch actuator. The torsion spring acts on a reaction plate subassembly which mechanically couples the torque generated by the spring to a rotor tube to operate the switch contacts. A spring guide subassembly maintains the spring in a predefined region to prevent the spring from deforming into a non-energy storing position during operation. The operator shaft, torque plate, reaction plate, spring guide, and spring are nested substantially concentrically about a predefined mounting axis. Left and right cam followers and a pivot lever combine to form a latch mechanism to prevent the switch actuator from changing position except when operated by a user.
