Patent number: 5785044Abstract: A fluid sample receptacle provides a means of assuring uncontaminated, multiple samples of a fluid specimen. An upper or isolated sample chamber and a lower or primary sample chamber provide redundant test samples. A cover or lid with a downwardly extending column includes a stopper with a removable plug attached to automatically seal the lower sample chamber when the cover is sealed across the top of the upper chamber. This feature guarantees that the sample chambers are sealed or isolated simultaneously and that the test samples are therefore identical when taken. Tamper evident seals prove that either sample has not been contaminated. A preferred embodiment provides a bellows assembly to accommodate variations in ambient pressure and to provide a positive means of expelling a precise quantity of fluid from the receptacle for testing.Type: GrantFiled: April 18, 1996Date of Patent: July 28, 1998Assignee: KVM Technologies, Inc.Inventors: James W.

Patent number: 5549141Abstract: A method for dispensing a sample of liquid from a sealed thermoplastic container which includes both a volumetrically flexible chamber holding the liquid and also a plurality of spaced axially vertical nozzles on the container underside, the nozzles having an inlet in fluid communication with the chamber. The container is first manipulated to increase the volume of the chamber, rotated from a right side up position to an upside down position, and after the two preceding operations an axial opening is non-invasively created in the nozzle while the container is upside down without decreasing the volume of the chamber. The container is then rotated from the upside down position to a right side up position without decreasing the volume of the chamber, manipulated to decrease the volume of the chamber and expel a sample of the liquid from the chamber through the nozzle opening, then rotated to an upside down position and the opening in the nozzle is closed by melting and clamping it closed.Type: GrantFiled: July 19, 1994Date of Patent: August 27, 1996Assignee: KVM Technologies, Inc.Inventors: James W.

Patent number: 4689303Abstract: Described herein is a controlled circulation incubator device having a plurality of plate receiving trays held by a tray bracket. Heated air is circulated by a blower and heater assembly around the trays held by the tray bracket and the temperature of the flowing heated air is sensed by a thermister included in a temperature controller circuit. The termister is coupled in a circuit so that its resistance determines the amount of heating provided by the heater portion of the blower and heater assembly. Each of the trays have a front lid and a back lip and the plurality of trays are offset from one another within the confines of the incubator device. The angle of the back lip and the amount of offset are selected so that each of the back lips are positioned in a generally planar surface. This causes the front lip, which extend at a slight angle from the receiving trays, to extend into the circulating air stream and air is forced between adjacent trays to heat the contents held by the trays.Type: GrantFiled: February 26, 1986Date of Patent: August 25, 1987Assignee: KVM Engineering, Inc.Inventors: Thomas L.
