  • Patent number: 10645886
    Abstract: The disclosure relates to a plant growth apparatus and related system to grow and maintain plants under controlled biotic conditions, for example to grow axenic (microbe-free) plants, gnotobiotic (defined microbiota) plants, and holoxenic (complex, or undefined microbiota) plants. This system allows aseptic bottom irrigation with water, soluble nutrients, chemicals, and/or microbiota. Plants can be inverted for dipping and/or vacuum infiltration. The system also allows for passive (gravity) drainage, thereby allowing for gas exchange and preventing root anoxia. A variety of plant growth substrates can be used within the plant growth apparatus as a plant growth medium. The plant growth apparatus, containing the growth substrate medium, can be completely flushed via the drainage port to remove potential toxic byproducts of the sterilization processes. The entire system is suitably constructed using autoclavable material.

  • Patent number: 8872055
    Abstract: A track rail heating assembly that is adapted to position a heater element in spaced relation proximate to a surface of a track rail of a railroad. The assembly includes at least one heating element, and a housing that is operable to at least partially surround the heating element while positioning the heating element near to track rail. The hood positions the heating element relative to the rail section such that a gap exists between the heating element and the rail section. As the heating element does not contact the rail, the heating element cannot form an electrical by-pass for signals passing through the rail section. The assembly further incorporates a flexible barrier that at least partially isolates a side surface of the track rail from ambient conditions to reduce heat loss.

    Abstract: A microelectromechanical heating apparatus and fluid preconcentrator device utilizing same wherein heating elements of the apparatus are sized and spaced to substantially uniformly heat a heating chamber within a heater of the apparatus. Tall, thermally-isolated heating elements are fabricated in Si using high aspect ratio etching technology. These tall heating elements have large surface area to provide large adsorbent capacity needed for high efficiency preconcentrators in a micro gas chromatography system (&mgr;GC). The tall heating elements are surrounded by air gaps to provide good thermal isolation, which is important for a low power preconcentrator in the &mgr;GC system.

  • Patent number: 6133551
    Abstract: A gas or electrically heated kiln furnace in which the hearth is stationary and an outer shell or wall with a door for access rotates around a stationary hearth. Loading and unloading is accomplished by rotating the outer shell to align the door with a position where a workpiece is to be inserted or removed. The kiln can be used as an up draft or down draft kiln, as a single chamber or a progressive chamber kiln. This kiln uses minimum floor space in that a circular shell is not rolled back but rotated about a hearth, around a vertical axis.

  • Patent number: 6117687
    Abstract: A controlled atmosphere incubator having an interior chamber surrounded by a heated water jacket. A glass access door of the chamber is directly heated by a clear, electrically conductive coating. The door is sealed against the perimeter of the opening by a readily replaceable gasket and is field reversible due to unique hinge mounting assemblies. An easily accessed blower assembly is located within the chamber and includes a HEPA filter readily replaceable by the user from within the chamber. A filtered air exchange system is provided for limiting the maximum level of humidity in the chamber. The incubator control maintains constant power output from the blower motor so that the heat output of the motor is also constant. A voltage compensated temperature control is also provided for the heaters associated with the water jacket. Compensation for environmental conditions inside the chamber is also provided by the control for producing more accurate readings of carbon dioxide levels.
