Patent number: 6220103Abstract: A vortex detector comprises a generally cylindrical housing or body that defines a flow passage extending from an upstream end to a downstream end. A vortex generator disposed diametrically across the cylindrical housing near the upstream end of the cylindrical housing and oriented substantially perpendicular to the longitudinal central axis of the flow passage generates a vortex street in a fluid flowing in the flow passage. The vortex street created by the vortex generator impacts a vane located downstream of the vortex generator and connected at one end to the cylindrical housing substantially spans the flow passage diametrically and substantially parallel to the vortex generator such that vibrations or motion are generated in the vane. The end of the vane connected to the housing includes an area of reduced thickness that acts as a resilient, elastic hinged joint for the motion of the vane.Type: GrantFiled: July 15, 1996Date of Patent: April 24, 2001Assignee: Engineering Measurements CompanyInventors: Charles E.

Patent number: 6077163Abstract: The present invention is directed generally to a method and apparatus for operating a gaming device having a flat rate play session costing a flat rate price. The flat rate play session spans multiple plays on the gaming device over a pre-established duration. The gaming device identifies price parameters and determines the flat rate price of playing the gaming device based on those price parameters. In one embodiment, identifying price parameters includes receiving player selected price parameters. In another embodiment, price parameters further incorporate operator selected price parameters. Should the player decide to pay the flat rate price, the player simply deposits the necessary funds into the gaming device or makes a credit account available for the gaming device to debit. Once the player initiates play, the gaming device tracks the duration remaining in the flat rate play session and stops the play when the given period has elapsed.Type: GrantFiled: June 23, 1997Date of Patent: June 20, 2000Assignee: Walker Digital, LLCInventors: Jay S.

Patent number: 5820641Abstract: The liquid cooled trap for effectively and efficiently collecting condensable vapor in a chemical vapor reaction system includes two stages. The first stage includes an entrance area to the trap that is purposely designed to be large in space and a very poor heat exchanger in order to avoid condensation and resulting solid deposits that could clog the entrance port to the trap. The second stage comprises a better heat exchanger to spread the condensation and deposits efficiently over a larger surface area and a longer flow path. The second stage is a very efficient heat exchanger to clean up and remove whatever small amount of the condensable vapor remains after the first stage of the trap. The second stage includes cooling coil tubes and cooling cones or fins to increase the overall efficiency of the trap be increasing the interior surfaces upon which the flowing condensable vapor can condense, while not significantly reducing the flow conductance of the trap.Type: GrantFiled: February 9, 1996Date of Patent: October 13, 1998Assignee: MKS Instruments, Inc.Inventors: Youfan Gu, Dana S.

Patent number: 5793603Abstract: A capacitor assembled in the form of a lightweight structural panel and including isolated capacitor cells. Each of the cells includes a honeycomb structure wherein each film-like layer in the honeycomb structure is an electrode stack. Each of the electrode stacks includes an elongated cathode, an elongated separator, and an elongated anode. The separator is wetted with an electrolyte solution to enhance the dielectric properties of the separator. Alternatively, the capacitor cell could be composed of a foam-like cathode, foam-like separator, and a foam-like anode. With either embodiment, the invention achieves the storage of electrostatic energy in a structure with a multitude of voids defined therein so that the structure is relatively stiff, yet light weight.Type: GrantFiled: November 19, 1996Date of Patent: August 11, 1998Assignee: Boundless Corp.Inventor: Philip C.
