20090100898 | System, apparatus and method for dispensing chemical vapor - This invention relates to a system for testing the operation of a detection instrument, which comprises a first enclosure having at least two ports and containing a fluid comprising a substance detectable in gas form by the instrument, said fluid being present in part as a vapor phase and in part as a liquid phase in equilibrium with one another, said first enclosure being interconnected with the instrument such that the fluid contained in the first enclosure can be dispensed to the instrument via at least one port of said first enclosure; a second enclosure having at least one port and containing either the same or a different fluid in gas form as compared with the first enclosure, said second enclosure being adapted for selective dispensing of a known or ascertainable mass of the fluid contained therein via at least one port thereof, and being interconnected with the first enclosure such that said mass can be introduced into the volume within said first enclosure through at least one port thereof, thereby to displace a correlative mass of the vapor phase fluid contained in the first enclosure causing said correlative mass to be dispensed to said instrument; and a valve in communicating relationship with said first enclosure and positioned such that, when the first enclosure is interconnected with said instrument, the valve is interposed between the interconnected first enclosure and instrument, which valve is capable of selectively permitting flow to said instrument of said vapor phase fluid dispensed from the first enclosure upon being displaced by said introduction of fluid from the second enclosure; the invention also relates to apparatus for implementing and a method involving same. | 04-23-2009 |
20110227740 | PERSONNEL LOCATION AND MONITORING SYSTEM AND METHOD FOR ENCLOSED FACILITIES - A wireless time-of-flight distance measurement device a motion detector is used at each of a plurality of stations in a wireless network in an enclosed facility to accurately locate a badge-wearing person near the station. The location, badge number and time of detection are transmitted through the network and stored in a computer memory. In a healthcare facility, hand washing detectors are located at some of the stations and caused to energize a hand wash status indicator light on the badge when the wearer has washed his or her hands. The light remains “on” for only a certain length of time, but will be extinguished sooner by a monitor device near each patient when the healthcare worker leaves the vicinity of the patient. These events also are transmitted and stored so that a timed record of each worker's hand washing and visits to patients is created. | 09-22-2011 |
20120217011 | Apparatus and method for high pressure abrasive fluid injection - A system for injecting high pressure abrasive fluid into an abrasive jet tool in a wellbore comprises an abrasives hopper; a slurry tank connected to the abrasives hopper; a low pressure abrasive pump connected to the slurry tank; a first high pressure vessel connected to the low pressure pump through a first high pressure valve; a high pressure non-abrasive pump connected to the first high pressure vessel through a second high pressure valve; and an abrasive jet tool connected to the first high pressure vessel through a third high pressure valve. | 08-30-2012 |
20150083424 | APPARATUS AND METHOD FOR HIGH PRESSURE ABRASIVE FLUID INJECTION - A system for injecting high pressure abrasive fluid into an abrasive jet tool in a wellbore comprises an abrasives hopper; a slurry tank connected to the abrasives hopper; a low pressure abrasive pump connected to the slurry tank; a first high pressure vessel connected to the low pressure pump through a first high pressure valve; a high pressure non-abrasive pump connected to the first high pressure vessel through a second high pressure valve; and an abrasive jet tool connected to the first high pressure vessel through a third high pressure valve. | 03-26-2015 |
20160047779 | PORTABLE FUEL DILUTION METER AND METHOD - A portable fuel dilution meter and method includes a plurality of sample bottles each with a lid securable thereto and an absorbent material in the bottle. A housing includes a sample bottle receptacle and a hinged head unit over the receptacle including at least a first needle piercing the lid of a sample bottle loaded into the housing receptacle and extending into the headspace of the sample bottle when the head is closed. A vapor sensor is fluidly coupled to the first needle for analyzing vapors in the headspace of the sample bottle. | 02-18-2016 |
