Abstract: A unitized oil seal having an annular inner seal case (12) having a J-shaped cross-section formed by an inner wall (24) and a first axial flange (28) interconnected by a first radial flange (26).  The oil seal also has an annular outer seal case (14) having a J-shaped cross-section formed by an outer wall (40) which is connected to a second axial flange (44) by a second radial flange (42). A primary seal element (16) is secured to the second axial flange (44) and extends to the outwardly facing surface (54) of the inner wall (24). An auxiliary seal element (18) is secured to the first axial flange (28) and extends to the inwardly facing surface (38) of the outer wall (40). In one embodiment, the primary and auxiliary seal elements (16) and (18) may be cammed over radially extending lips (56) and (58) formed on the inner and outer walls (24) and (40). Separation of the inner and outer seal cases (14) and (16) is resisted by radial pressure exerted by the seal elements and the radial lips.

Title: Apparatus for preventing separation of a down-hole motor from a drill string
Inventor: BEASLEY THOMAS R
IPC: E21B47/18
Filed: 1991-10-18
Abstract: APPARATUS FOR PREVENTING SEPARATION OF A DOWN-HOLE MOTOR FROM A DRILL STRING                     ABSTRACT      An apparatus is disclosed for use in a drill string 10 to prevent separation of a lower tubular member 16 from an upper tubular member 15 by a rotational force applied from a down-hole motor 22.  The down-hole motor 22 is rotated by drilling fluid pumped from the surface, through a passage formed within the drill string 10, and into the down-hole motor 22.  A valve 36 is positioned in the passage in the drill string 10 and has a first operating position adapted for passing the drilling fluid to the down-hole motor 22, and a second operating position adapted for substantially blocking the drilling fluid from being delivered through the down-hole motor 22.  The valve is of a two piece construction, having a first body 44 connected to an upper tubular section 14 and a second body 46 connected to the down-hole motor 22.  Thus, longitudinal movement between the upper tubular section 14 and the down-hole motor 22, which is a result of rotation of the lower tubular section 16 by the motor 22, causes corresponding longitudinal movement of the first and second bodies 44, 46 between the first and second operating positions.

Filed: 1991-10-18
Abstract: A lidar with a laser transmitter for transmitting a laser beam and a receiver having receiving optics for detecting radiation reflected back from the beam by aerosol particles in the atmosphere, the receiver having an optical axis aligned with the beam. The receiver includes a number of radiation receiving elements such as concentric radiation detector elements placed in the receiving optics focal plane so that these concentric detector elements can measure backscatter radiation from the beam at several fields of view simultaneously. Backscattered signals at fields of view larger than the laser beams's divergence are due to multiple scattering. The unknown backscatter coefficient can then be eliminated by ratioing the lidar returns at the different fields of view.

Title: Method and apparatus for minimizing environmental release of toxic compounds in the incineration of wastes
Inventor: LERNER BERNARD J
IPC: B01D53/50
Filed: 1992-06-09
Abstract: A method and apparatus for minimizing the environmental release of acids and toxic organic compounds from a waste incinerator-air pollution control train. The apparatus comprises an incinerator (1), a gas cooling means such as a waste heat boiler (7) or quench chamber, a means for the partial removal of acid gases and dioxins by contact with either finely-divided alkaline solids or alternatively, by an alkaline solution in a spray drier-absorber, a dry solids collection means such as a fabric filter or electrostatic precipitator, a wet scrubber means (22) for residual metal, dioxin/acid gas removal and an induced draft fan. In the method of this invention, the final wet scrubber stage operates without alkaline neutralization, but under scrubber acid concentrations and operating conditions that provide an exhaust gas within compliance limits of emission regulations. The contaminated liquor blowdown from the wet scrubber, which contains toxic organics and acids, is recycled back into the incinerator. The aqueous acid liquor blown down to the incineration is vaporized therein, most of the toxic organic content of the liquid is destroyed by the re-incineration, and the regenerated acid gases are largely removed by the first dry scrubbing stage. <IMAGE>

IPC: G01G15/00
Filed: 1991-10-21
Abstract: A method and system (10) for dispensing a fluid to provide a predetermined weight percent concentration of a sample material (22) to the fluid (24). An estimated density value for the fluid is used to determine the volume of fluid to dispense in an initial injection of fluid which is less than the total volume of fluid required to achieve the predetermined weight percent concentration. A  working fluid density is then determined from the volume of fluid dispensed and a measurement of the weight of the fluid dispensed. The working density is then used to determine the volume of fluid to dispense in a subsequent injection. Preferably, at least three fluid injections are performed, and the working density is determined after each fluid injection.
