Title: No-vent dry kiln
Inventor: GOODWIN TOM E III
IPC: F26B21/10
Filed: 1996-01-16
Granted: 2007-06-05
Abstract: A no-vent dry kiln for drying wood products such as lumber. The kiln has a dehumidification unit to remove excess moisture from the air utilized as the drying media. The dry bulb and wet bulb temperatures of the air within the kiln en- closure are precisely monitored to control the conditions of the atmosphere within the kiln enclosure. The kiln has a de- humidification unit to remove excess moisture from the air and to retain the sensible heat of the air stream passing through the dehumidification unit. The air stream, under a controlled flow rate passes through a first coil which removes the sen- sible heat from the air stream to lower the temperature of the air stream to at or below its saturation temperature. the heat removed by the first coil is transferred to a third coil downstream. A second coil downstream from the first coil lowers the temperature of the air stream well below the dew point causing the condensing of moisture. The condensed mois- ture is removed by a condensate removal system. The dehumid- ified air the passes through the third coil where the heat previously removed by the first coil is reintroduced into the air stream, adding heat if necessary to bring the air stream up to the desired dry bulb temperature. The air stream is the admixed with the drying air within the kiln enclosure. Both the dry bulb and wet bulb temperatures of the air are precisely controlled to provide a desired drying schedule.

Granted: 1999-07-20
Abstract: This invention relates to a new and useful improvement in a wiper for use on thewindshields of vehicles, such as automobiles, trucks, trains, boats, airplanes and the like, and more particularly to improvements in a windshield wiper which is electrically heated so as to prevent the accumulation of ice, sleet or snow on the wiper blade. Moreparticularly, this invention has references to an improved heating arrangement designed to be used in windshield wiper assemblies with minimum modification or redesign of the blade-supporting, oscillating means, etc.  A spiral coiled heating element of resistance wire and a fluid dispensing arrangement for dispensing heated fluid are disposedsubstantially within the entire length of the passageway of the wiper blade. Tubes of electrical conductive material enter the passageway at the first and second passageway ends thus providing a means for both heat and/or fluid conveyance and an entrance and exits for the current and fluid. The ends are then sealed with a moisture proof sealant which also serves to maintain stability of end connections. The heating arrangement is connected to the vehicle battery to heat the heating element and fluid contained inside the blade passageway allowing the entire outer circumference of the wiper body and the wiping surfaces to melt ice surrounding the wiper and ice present on the windshield. Therefore the fluid is prevented from freeze-up and spray nozzle remains operable. The reciprocating spray nozzle is designed to spray ahead of wiper in both upward and downward movement. If desired the fluid dispensing arrangement can be used without heating the fluid.

Granted: 2008-11-04
Abstract: An error detection mechanism for detecting programming errors in a computer program. A component of the computer program, e.g., a procedure or function of the computer program, is analyzed to determine the effect of the component on resources used by the computer program. A component is analyzed by traversing the computer instructions, i.e., statements, of the component and tracking the state of resources used by the components as affected by the statements of the component. Each resource has a prescribed behavior represented by a number of states and transition between states. Violations in the prescribed behavior of a resource resulting from an emulated execution of the statements of the component are detected and reported as programming errors. Resources used by two or more components are modelled by modelling externals of the components. The effect of execution of a component on externals and resources of the component is determined by traversing one or more possible control flow paths through the component and tracking the use of each external and resource by each statement of each control flow path. Once the effect of execution of a component on externals and resources of the component is determined, a model of the component is created and used to model externals and resources of other components which invoke the modelled component.
