Abstract: An airflow diffuser (diffuser fan) comprises: a blade wheel formed of blade members 30, spoke members 40 and a hub member 50; a shaft member 20 forming an axis of rotation of the blade wheel; and a suspension member 10 suspending the shaft member 20 from a ceiling surface. This airflow diffuser (diffuser fan) is located so that air blown out from the air outlets of an air conditioner comes in contact with and rotates the blade members. Also, the rotating blade members receive the blown air in succession, and by deflecting the air, diffuse the blown air throughout the entire air-conditioned space.

Abstract: A vehicle door seal venting system is provided for venting air trapped in the seal gap between two or more spaced environmental seals. As the vehicle door transitions to a closed position, the seals engage between the vehicle door and vehicle body door opening, acting to closeout the seal gap. The compression of the seal gap as the door further closes results in pressurization of the trapped air, which then acts to resist closure of the vehicle door, therefore requiring that additional closure force be applied to fully close the door. The vehicle door seal venting system relieves the pressurized air from between the seals without compromising the integrity of the seals or overall noise and sealing performance of the door system.

Abstract: A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference. The moisture trapped in the desiccant is then released to the outside ambient. In the night time, the green house enclosure cools, which generates a flow to the inside of the enclosure. The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure.

Abstract: A mounting system that is used to mount a solar panel array to a flat roof. The system utilizes mounting supports that hold solar panels at an inclined angle. Each mounting support includes a first mounting ledge, a second mounting ledge, a flat base section and an inclined section that is disposed between the flat base section and the first mounting ledge. The first mounting ledge, second mounting ledge, flat base section and inclined section are all integrally formed from a common sheet of metal. A solar panel is attached between two of the mounting supports. Once mounted, the solar panel extends from the first mounting ledge of a first mounting support to a second mounting ledge of a second mounting support. Weights are then placed on the flat base section of the mounting supports to passively anchor the assembly to the roof.

Abstract: When a truck engine (12) is not running, an auxiliary coolant heater (32) can heat engine coolant and pump it through an occupant compartment heater (16). A coolant flow control system (10), including a valve assembly (84), associates the auxiliary heater (32) with both the occupant compartment heater (16) and engine (12) for selectively distributing heated coolant. When engine (12) has been running and is shut off, auxiliary heater (32) can be turned on and valve assembly (84) operated for occupant compartment heating while keeping the engine (12) warm. When the engine is cold, the auxiliary heater can be turned on and the valve assembly can be operated for engine pre-heating prior to starting.

Abstract: A charcoal cooking grate which is hinged to fold up to trap charcoal in a tight pile that is necessary for efficient burning. The grate folds completely over the top and lays flat to allow for three sheets of crumpled up newspaper to be placed under one side. Both sides then fold up to trap the charcoal in the middle of the grate. There are also two hinged sides which fold up to trap the charcoal. These hinged sides wrap around the grate to complete the enclosure. The charcoal can then be loaded onto the center of the cooking grate. Because you have a defined area to pour the charcoal, you get the exact amount of charcoal that is needed to use the grill. After the coals have become hot enough to cook with, then the chains can simply be pulled to release the hinged sides and the end grates to their original positions. The charcoal is automatically dispersed across the charcoal grate as the end grates are lowered back down to a flat position.
