Patent number: 6438862Abstract: The invention is a distributed airways airflow dryer system for coffee beans and other such bulk crops. The interior volume or container of the dryer or dehydrator system that holds the bulk crops, is filled with an airways network structure that provides uniformly distributed open wall airflow passageways in the bulk crops. The airflow passages communicate with airflow openings in the walls or bottom of the container, to divide and admit the drying airflow into and through the full volume of the bulk crops as a large number of individual airstreams. Corrugated, ribbed, or cross-ribbed airflow plates are preferred embodiments that provide narrow open grooves or channels that expose the beans or kernels of the bulk crop directly to the airflow. This results in faster drying and greater uniformity of the drying effect on the full volume of the bulk crops.Type: GrantFiled: June 13, 2000Date of Patent: August 27, 2002Inventor: Paul B Soucy

Patent number: 6435426Abstract: A pressure proof gasket plate for use with a cup and special or modified lid assembly for a spray gun, consisting of a cup with a first end configured with fittings suitable for attachment to the feed port of the spray gun and a second end with a large opening for access and filling, and a domed lid, with an external mechanism for providing a compressive attachment of the lid to the cup with the gasket plate in between. The floating gasket plate has a compressible gasket configured on its inside surface so as to form a seal when it contacts the edge of the cup as the lid is applied to the cup. The floating gasket plate is sealed to the cup by pressure on its periphery as applied by the domed lid. The floating gasket plate is made of such material and thickness as to resist deflection and deformation under normal working pressure of the spray gun.Type: GrantFiled: May 11, 2000Date of Patent: August 20, 2002Inventor: William H.

Patent number: 6394316Abstract: A pump for dispensing particulate-ladened or heavily viscous fluids such as grit-ladened or granulated hand soap or lotion, has a compressible pump cavity with an inlet and a streamlined outlet, with a backflow check valve associated with the inlet and a nozzle assembly connected to the outlet. In the nozzle assembly, a spring loaded outflow ball valve resists outflow until sufficient fluid pressure is applied from the pump cavity. A minimally flow restrictive spring base support structure holds the base of the spring apart from the nozzle tip, creating a fluid flow path around the check ball and spring to the nozzle tip.Type: GrantFiled: January 24, 2001Date of Patent: May 28, 2002Inventor: Warren S.

Patent number: 6396770Abstract: This invention is a steerable thermoacoustic array system for directing information between an object that is above the surface of the water and a sound detector that is beneath the surface of the water. The foregoing system comprises a laser or particle accelerator that is located above the water's surface. The laser or particle beam produces a light beam or particle beam which contains information that is moved along a small layer of water at the air/water interface at a speed equal to the speed of sound in water divided by the steering angle of the laser so that the light beam or particle beam is absorbed by the water causing the water to expand and produce a series of acousitic Braves that constructively interfere with each other and travel towards the sound detector.Type: GrantFiled: June 28, 1982Date of Patent: May 28, 2002Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Charles A. Carey, Harvey C. Woodsum, Richard A. Jensen

Patent number: 6390684Abstract: In a reciprocating rotor device such as a scanning galvanometer, a bearing assembly consisting of a rheological bearing coupler interposed between the rotor shaft and the bearing support structure or housing, where the rheological bearing coupler is relatively stiff during constant-velocity portions of rotor rotation, assuring adequate geometrical precision of the rotor within the rotor housing during the scanning phase. When loaded beyond a design load threshold by acceleration-induced moments causing lateral or asymmetrical force applied between the shaft and the bearing support structure during changes in rotor speed, becomes relatively compliant or resilient, absorbing a portion of the load at the expense of momentary axial misalignment of the rotor, then returning to original shape and realigning the rotor to it's correct precision axial position when the acceleration forces are abated.Type: GrantFiled: July 3, 2001Date of Patent: May 21, 2002Assignee: GSI Lumonics CorporationInventor: David C.

Patent number: 6384792Abstract: The present invention features a dual mode, meander line loaded antenna (MLA) having an additional wideband plate or hat located above the horizontal top surface of the MLA antenna. The upper plate is spaced a predetermined distance above the MLA and held in place by dielectric blocks of a predetermined thickness. By properly spacing the additional plate, simultaneous wideband and narrowband reception can be performed. The added upper plate generally does not interfere with the usual narrowband operation of the original antenna structure. The modified antenna can accept radio frequency signals across a wide range of frequencies. The additional upper plate can be retrofitted to existing MLAs to modify them for dual mode operation.Type: GrantFiled: June 14, 2001Date of Patent: May 7, 2002Assignee: BAE SystemsInformation Electronic Systems Integration, Inc.Inventor: John T.

Patent number: 6379127Abstract: A submersible electric motor driven pump includes a motor chamber and a pump chamber separated by a seal chamber. Inboard and outboard shaft seals immersed in an oil buffer fluid within the seal chamber restrict the flow of liquid from the seal chamber into the pump and motor chambers. An integral or externally mounted pre-pressurized buffer fluid reservoir maintains a positive fluid pressure in the seal chamber relative to the external pressure at working depth, and suitable buffer fluid level within the chamber, preventing the ingress of the pumped media through the outboard seal. A unique impeller design circulates fluid within the seal chamber in the region of the outboard shaft seal, allowing continuous run dry operation when used in conjunction with an integrally cooled motor design. A cartridge shaft sleeve subassembly permits with a bearing configured between the inboard and outboard seals, facilitates maintenance.Type: GrantFiled: September 29, 2000Date of Patent: April 30, 2002Assignee: Lawrence Pumps, Inc.Inventors: Dale B. Andrews, D. Paul Russell, Michael C. Witzgall
