Patent number: 6732594Abstract: A system for dispensing cryogenic liquid to a use device includes a bulk storage tank providing LNG to a sump containing a meter submerged in LNG. A temperature probe is also submerged in the LNG. A dispensing line is positioned between the meter and dispensing hose and includes a dispensing valve. A drain line bypasses the dispensing valve and features a check valve so that LNG trapped in the hose after dispensing is returned to the sump due to pressurization by ambient heat. A capacitance probe is submerged in the LNG in the sump and provides a dielectric that is compared by a microprocessor with the dielectric for pure methane at the same temperature to determine the purity of the LNG. An approximate linear relation between density and dielectric may be used to determine density and mass flow for the LNG from the measured dielectric.Type: GrantFiled: February 13, 2003Date of Patent: May 11, 2004Assignee: Chart Inc.Inventors: Thomas K. Drube, Paul A. Drube, Claus D. Emmer, Gilbert J. Bily, Jesse Gamble

Patent number: 6732595Abstract: A method of and system for analyzing the mass flow rate of a fluid flowing in a conduit wherein ultrasonic energy is transmitted along multiple v paths in multiple parallel quadrature planes through the fluid, the transit time of the ultrasonic energy through the fluid with and against the flow direction of the fluid is measured, and the flow velocity of the fluid in each quadrature plane is calculated based on the transit time in each quadrature plane. The density of the fluid in each quadrature plane is then determined and quadrature integration of the product of the fluid density and fluid velocity in each quadrature plane is performed to calculate the total mass flow rate of the fluid more accurately by eliminating errors associated with assuming that the density of the fluid in the conduit is uniform.Type: GrantFiled: September 30, 2002Date of Patent: May 11, 2004Assignee: Panametrics, Inc.Inventor: Lawrence C.

Patent number: 6732596Abstract: A gas mass flow meter includes an elongated channel extending through a high thermal mass body and a critical flow nozzle in a downstream portion of the channel. A heat exchanger is provided upstream in the channel. Gas is forced through the heat exchanger and the critical flow nozzle at a flow rate of up to 5000 slm and at sufficiently high-pressure to ensure critical flow of the gas through the critical flow nozzle. The heat exchanger brings the gas close to the temperature of the high thermal mass body. The pressure of the gas is measured upstream and downstream from the nozzle and the temperature of the gas emerging from the heat exchanger is measured. The mass flow rate of gas through critical flow nozzle is computed from the upstream pressure, downstream pressure, temperature of the high thermal mass body, density of the gas, and a dimensional characteristic of the critical flow nozzle.Type: GrantFiled: November 12, 2002Date of Patent: May 11, 2004Assignee: CalAmerica Corp.Inventor: Pierre R.

Patent number: 6732597Abstract: The present invention is an apparatus for precisely dispensing a desired weight of a particulate material from the outlet of a material hopper. The apparatus is made up of a trap chamber for collecting an initial weight that is less than the desired weight of the particulate material. The trap chamber includes an upper surface with an inlet in communication with the hopper outlet and a lower surface including an outlet. The surface area of the inlet is smaller than the surface area of the trap chamber outlet. The invention also includes a dispensing valve having a closed position covering the trap chamber lower outlet opening and an open position uncovering the trap chamber lower outlet opening.Type: GrantFiled: November 14, 2002Date of Patent: May 11, 2004Inventor: Robert O. Brandt, Jr.

Patent number: 6732601Abstract: A control apparatus of an automated manual transmission includes an input shaft provided with a plurality of drive gears, an output shaft provided with a plurality of driven gears engaged with the drive gears, and a reverse idler gear engaging with gears for backward movement respectively provided at the input and output sides when a backward moving stage is selected, as a mechanism for backward moving. Further, there is provided with a bypass clutch capable of selectively transmitting or shutting a power of the input shaft to the output shaft. When the backward moving stage is selected (S1), the bypass clutch is engaged (S3) so as to stop a rotation of the input shaft (S4), and thereafter, the reverse idler gear and the backward moving gears are engaged with each other (S5). Thus, a shift operation to a reverse mode can be securely and smoothly executed for a short time.Type: GrantFiled: November 9, 2001Date of Patent: May 11, 2004Assignee: Fuji Jukogyo Kabushiki KaishaInventor: Hosei Suzuki
