Patent number: 6174423Abstract: A system for dipping workpieces into a coating tank that includes a conveyor disposed above the tank and a workpiece carrier movable on the conveyor along a path above the tank The carrier includes a box frame having pivotal corner connections and vertically spaced guide rollers disposed on lateraly opposed sides of the frame. Longing spaced cables suspend the carrier frame from winces on the conveyor for selectively raising and lowering the carrier with respect to the conveyor. The winches and cables are also selectively operable for rocking the carrier frame about a horizontal axis lateral to the path of travel along the conveyor. A pair of track rails are disposed in fixed position on laterally opposed sides of the conveyor for engaging the guide rollers on laterally opposed sides of the carrier frame during lowering of the frame into the tank and maintaining horizontal position of the carrier frame during rocking thereof within the tank.Type: GrantFiled: December 2, 1998Date of Patent: January 16, 2001Assignee: Acco Systems, Inc.Inventors: Christopher A. Wood, Richard G. Hooper

Patent number: 5577593Abstract: A carrier conveyor system wherein carriers are disengaged from a main conveyor in advance of a work station and re-engaged beyond the work station. A transfer conveyor is positioned such that it receives the carriers as they are disengaged from the main conveyor, transfers them as required to the work station, removes them from the work station after the work is performed, and returns them to the main conveyor. The transfer conveyor comprises a plurality of transfer assemblies arranged in succession along the carrier travel path, and each include right and left hand mirror-imaged belt modules that are mechanically drivingly cross-connected to each other.Type: GrantFiled: January 27, 1995Date of Patent: November 26, 1996Assignee: FKI Industries, Inc.Inventor: Richard G. Hooper

Patent number: 5570639Abstract: Apparatus for preventing runaway of trolleys in a power-and-free conveyor system that includes a friction bar that extends lengthwise of the free conveyor track on a side of the track remote from the power conveyor for motion lengthwise of the track at an acute angle to the direction of motion of the trolleys along the track. The friction bar is releasably biased laterally outwardly from the track and in a direction lengthwise of the track opposed to the direction of trolley motion on the track so that trolleys may travel freely along the free conveyor track past the bar.Type: GrantFiled: October 11, 1995Date of Patent: November 5, 1996Assignee: FKI Industries Inc.Inventors: Richard G. Hooper, Robert E. Mahu, Thomas A. Moroney

Patent number: 5082586Abstract: SO.sub.x /NO.sub.x pollution control reagent composition comprising from 0.1 to 25% urea in intimate admixture with dry, finely divided Nahcolite, a naturally occurring form of sodium bicarbonate. The composition is used in a process of removing SO.sub.x /NO.sub.x from the flue gases of utility and industrial plants, incinerators and the like by dry injection into a flue gas duct a sufficient distance upstream of a spent reagent collection device to provide above about 0.25 seconds of residence time of the reagent composition in the flue gas duct at temperatures in the range of above about 200.degree. F. followed by collection, preferably in an electrostatic precipitator. The Nahcolite reacts with the SO.sub.2 to form sodium sulfate and also removes NO.sub.x in the form of NO. The urea prevents the conversion of NO to NO.sub.2 by the Nahcolite, and maintains the concentration of the NO.sub.2 in the exit flu gases below the 50 parts per million visibility threshold (depending on ambient conditions).Type: GrantFiled: November 7, 1988Date of Patent: January 21, 1992Assignee: NaTec Resources, Inc.Inventor: Richard G. Hooper

Patent number: 5002741Abstract: SO.sub.x /NO.sub.x pollution control process comprising injecting into flue gas from 1 to 50% carbon (preferably 5-15%) along with a dry, finely divided sodium sorbent, preferably sodium bicarbonate or Nahcolite, a naturally occurring form of sodium bicarbonate. The process removes both SO.sub.x and NO.sub.x from the flue gases of utility and industrial plants, incinerators and the like by dry injection into a flue gas duct a sufficient distance upstream of a particulate collection device, such as an ESP or baghouse, to collect spent reagent and additive. The sodium reagent reacts with the SO.sub.2 to form sodium sulfate and also removes NO.sub.x in the form to NO. The carbon additive reacts with NO.sub.2 to reduce the concentration of the NO.sub.2 in the exit flue gases to below the NO.sub.2 brown plume visibility threshold (about 30 ppm NO.sub.2, not corrected to 0% O.sub.2, depending on stack diameter and ambient conditions).Type: GrantFiled: November 16, 1989Date of Patent: March 26, 1991Assignee: Natec Resources Inc.Inventor: Richard G. Hooper

Patent number: 4954324Abstract: Baghouse SO.sub.x /NO.sub.x pollution control process comprising injecting from 1 to 25% urea or ammonia along with dry, finely divided sodium bicarbonate or Nahcolite, a naturally occurring form of sodium bicarbonate. The process removes both SO.sub.x and NO.sub.x from the flue gases of utility and industrial plants, incinerators and the like by dry injection into a flue gas duct a sufficient distance upstream of a baghouse to collect spent reagent and additive. The sodium reagent reacts with the SO.sub.2 to form sodium sulfate and also removes NO.sub.x in the form of NO. The urea or ammonia additive prevents the conversion of NO to NO.sub.2 by the sodium reagent, and reduces the concentration of the NO.sub.2 in the exit flue gases to below the NO.sub.2 brown plume visibility threshold (about 30 ppm NO.sub.2, not corrected to 0% O.sub.2, depending on ambient conditions). The additive may be used wet (sprayed into the flue gases in a concentrated water solution) or dry.Type: GrantFiled: March 10, 1989Date of Patent: September 4, 1990Assignee: NaTec Resources, Inc.Inventor: Richard G.

Patent number: 4031753Abstract: An instrument for sampling both solid and liquid water particles in the atmosphere and continuously producing an electrical output response directly equivalent to the total percentage water content of the atmosphere sampled. The solid and/or liquid water particles are collected by using a large funnel shaped scoop of 100 cm.sup.2 to allow high volume collection at nominal aircraft speeds. The water is routed into the detection device which includes a concentric cylinder flow-through capacitor that varies in capacitance according to the dielectric of the fluid enclosed.Type: GrantFiled: August 20, 1976Date of Patent: June 28, 1977Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Richard G.
