Patent number: 6651480Abstract: The mass of particulate matter in a particle laden gas stream is measured using a single mass detector. The particle laden gas stream and a substantially identical but particle-free gas stream alternately engage the mass detector during successive measurement time periods. A difference between a reading provided by the mass detector for a current measurement time period and a reading provided by the mass detector for a consecutive measurement time period is determined. This difference intrinsically corrects for volatilization losses occurring during the current measurement time period. A measure of the mass or concentration of particulate matter in the particulate laden gas is determined from this difference.Type: GrantFiled: October 30, 2002Date of Patent: November 25, 2003Assignee: Rupprecht & Patashnick Company, Inc.Inventors: Harvey Patashnick, Georg Rupprecht

Patent number: 6138521Abstract: An air sampler having an automatic sample collector changer includes a supply magazine for holding a supply of fresh sample collectors and a receiving magazine for receiving and storing used collectors located aside a sampling station. A transfer mechanism transfers a fresh collector from the supply magazine to the sampling station and a used collector from the sampling station to an entrance of the receiving magazine. An automatic closer or plunger closes the entrance of the receiving magazine following transfer thereto of a used collector. The supply magazine can include an actuator for displacing a stack of sample collectors contained in said magazine. This stack may include interspersed air impervious covers. The transfer mechanism can transfer both a sample collector and a cover to the receiving magazine. Interspersing of covers with used sample collectors in the receiving magazine reduces volitization losses. For the same purpose, the temperature of the receiving magazine can be controlled.Type: GrantFiled: December 9, 1999Date of Patent: October 31, 2000Assignee: Rupprecht & Patashnick Company, Inc.Inventors: Lauren R.

Patent number: 6016688Abstract: The mass of particulate of an effluent gas flowing in a stack is directly measured with a mass measurement assembly supported within the stack. The mass measurement assembly preferably includes an inertial mass measurement transducer which provides near real-time mass readings. The mass measurement assembly also includes a particulate collector which can be equilibrated in situ. A pressure transducer measures a pressure differential across the equilibrated collector prior to sampling, to determine a pressure coefficient of frequency in a calibration operation. The pressure transducer also measures a pressure differential across the collector during sampling which measurement is used along with the pressure coefficient of frequency to derive an adjusted mass reading, corrected to compensate for pressure changes.Type: GrantFiled: November 12, 1998Date of Patent: January 25, 2000Assignee: Rupprecht & Patashnick Company, Inc.Inventors: John Hiss, III, Harvey Patashnick

Patent number: 5970781Abstract: The mass of particulate of an effluent gas flowing in a stack is directly measured with a mass measurement assembly supported within the stack. The mass measurement assembly preferably includes an inertial mass measurement transducer which provides near real-time mass readings. The mass measurement assembly also includes a particulate collector which can be equilibrated in situ. A conditioned gas line supplies clean, dry, heated conditioned gas to the collector for equilibration. The flow rate of the conditioned gas prevents effluent gas from reaching the collector during equilibration. The collector can be equilibrated in the stack before and after sampling and between intermittent sampling periods.Type: GrantFiled: May 14, 1998Date of Patent: October 26, 1999Assignee: Rupprecht & Patashnick Company, Inc.Inventors: John Hiss, III, Harvey Patashnick

Patent number: 5553507Abstract: An airborne particulate sampling monitor for collecting particulate in either a solid, liquid or gaseous state. The monitor includes at least two intakes, each of which accepts airborne particulate. Paired with and coupled to each intake is an appropriate particulate filter for sampling accepted airborne particulates. A vacuum pump establishes air flow into one of the intakes and a sampling process controller, coupled between each intake and filter pairing and to the vacuum pump, controls the vacuum pump's establishing of air flow into a selected particulate intake. Preferably, the vacuum pump and sampling process controller reside within a hub unit to which multiple satellite units can be coupled such that each satellite unit employs the vacuum pump and sampling process controller of the hub unit. Due to central processing, conditional sampling at one or more of the units is possible. Further details and manual particulate sampling methods are presented.Type: GrantFiled: June 5, 1995Date of Patent: September 10, 1996Assignee: Rupprecht & Patashnick Company, Inc.Inventors: Lauren R.

Patent number: 5401468Abstract: Carbon particulate concentration of diesel exhaust or other sampled gas is measured by collecting the particulate on a high efficiency filter or other collector while measuring the amount of sampled gas passing through the filter. Particulate collection occurs along an open ended collection flow path. The collected particulate is then heated in an oxygen rich environment to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured along a closed measurement flow path to derive a corresponding measurement of the amount of collected particulate. Particulate concentration is calculated by comparing the amount of carbon particulate with the measured amount of sampled gas. A computer controls automatic switching of operation along the collection and measurement flow paths for respective particulate collection and measurement cycles.Type: GrantFiled: January 18, 1994Date of Patent: March 28, 1995Assignee: Rupprecht & Patashnick CompanyInventors: Harvey Patashnick, Georg Rupprecht

Patent number: 5279970Abstract: Carbon particulate concentration of diesel exhaust or other sampled gas is measured by collecting the particulate on a high efficiency filter while measuring the amount of sampled gas passing through the filter. The filtered particulate is then heated in an oxygen rich environment to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured with a closed measurement loop to derive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of carbon particulate with the measured amount of sampled gas passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile carbon components within the particulate prior to the oxidation of the non-volatile carbon component.Type: GrantFiled: October 19, 1992Date of Patent: January 18, 1994Assignee: Rupprecht & Patashnick Company, Inc.Inventors: Harvey Patashnick, Georg Rupprecht

Patent number: 4838371Abstract: A suspension system for an inertial balance constrains the weighing platform when oscillated to undergo uniform linear motion, thereby ensuring high measurement accuracy. The suspension system includes a supporting framework and a first plurality of elongate elastic support members for suspending the weighing platform from the supporting framework. The elongate support members are disposed in a common plane when the weighing platform is at rest and their inner ends intersect at a first common point to which the weighing platform is firmly linked. A second plurality of such elongate support members is similarly disposed in a second common plane parallel to but spaced from the first common plane. A stiff connecting rod joins the intersection points of the two pluralities and also serves to support the weighing platform and, in conjunction with a feedback system, serves to induce and maintain the weighing platform in oscillation at a resonant frequency dependent upon mass loading.Type: GrantFiled: January 22, 1988Date of Patent: June 13, 1989Assignee: Rupprecht & Patashnick Co., Inc.Inventors: Georg Rupprecht, Harvey Patashnick
