Abstract: A condensate pump includes a condensate reservoir, a liquid level float sensor operable to sense a liquid level within the condensate reservoir, and a pressure/vent valve including a pressure source, a pressure vent, and a primary piston slidably supported in a primary cylinder and sliding in the primary cylinder responsive to the liquid level sensor. A secondary piston is slidably supported in a secondary cylinder and moves responsive to a movement of the primary piston between a first secondary-piston position wherein the pressure source is in communication with a gas space of the condensate reservoir and the pressure vent is isolated from the gas space, and a second secondary-piston position wherein the pressure source is isolated from the gas space and the pressure vent is in communication with the gas space.

Abstract: The present invention provides an apparatus for dissolving a gas in a liquid, the apparatus comprising (a) a closed vessel containing a liquid at a predetermined level, (b) a contactor module at least partially immersed in the liquid having (1) a gas supply channel to the bore side of the fibers, (2) a liquid supply channel to the shell side of the fibers, and (3) an exit port for transport of a gas-containing liquid, and (c) the remaining space in the closed vessel being occupied by a pressurized gas. The liquid prepared in the apparatus of the present invention containing a dissolved gas, is used to prepare beverages, such as coffee, tea, soda, chocolate and the like, whether hot or cold.

Abstract: A fan assembly (14) for ventilating an essentially closed chamber such as an inflatable storage chamber for a motor vehicle comprises a base plate (17) for mounting over an opening through a wall (13) of the chamber, the base plate defining an aperture (21) therethrough and an electrically-driven fan (28) being arranged to draw air from a first plenum (31) upstream of the fan and drive the drawn air into the chamber. An air treatment unit (25) is disposed over an opening through the base plate between the chamber and the first plenum (31). A first filter (22) is disposed in an opening between the first plenum (31) and the external atmosphere (35). In this way, air driven into the chamber by the fan (28) will be a mixture of air drawn from the external atmosphere through the first filter (22) and air drawn from the chamber through the air treatment unit (25) into the first plenum (31), to be recirculated into the chamber.

Abstract: Apparatus primarily for the storage of a motor vehicle comprises a base sheet, an inner cover sheet defining in combination with the base sheet a storage chamber and an outer cover sheet substantially wholly overlying the inner cover sheet. The inner and outer cover sheets are joined together around their peripheral edges and are at least partially releasable from the base sheet, so as to give access to the interior of the storage chamber. At least one fan assembly is provided to drive air from the external ambient into the storage chamber so as to inflate it and air is allowed slowly to leak out of that chamber, into the space between the inner and outer cover sheets and, and then to the external ambient. In this way, the space between the inner and outer cover sheets is inflated by air bleeding from the storage chamber into that space.

Abstract: This invention relates to a vehicle cargo lift having a bed (9) having posts (10) parallel to each other extending from the bed (9), a support frame (2) having two opposed side frames forming a well therebetween to accommodate the bed (9), at least one hollow elongated member (7) located in each side frame, drive devices (8) to move the bed (9) between a raised transport position and a ground engaging loading positions such that the bed (9) retains substantially the same orientation throughout its movement between the transport position and the loading position with the hollow elongated members (7) being telescopically engaged with respective posts (10) of the bed (9).

The inner and outer cover sheets are joined together around their peripheral edges and are at least partially releasable from the base sheet, so as to give access to the interior of the storage chamber. At least one fan assembly (19) is provided to drive air from the external ambient into the storage chamber so as to inflate it and air is allowed slowly to leak out of that chamber, either directly or indirectly through the space between the inner and outer cover sheets (11) and (12), to the external ambient. The space between the inner and outer cover sheets may be inflated by air bleeding from the storage chamber into that space, or that space may separately be inflated.

Abstract: An inflatable storage chamber defined by a flexible membrane comprises means for access to the chamber and means for inflating the chamber. The chamber is designed for storing items such as motor vehicles, machinery and furniture.
