  • Patent number: 7234270
    Abstract: A greenhouse has an exterior curtain wall structure formed by spaced tubular posts carrying external transparent panels and bottom non-transparent wall panels below a sill with the panels spanning the posts. A plurality of elongate benches is located within the interior at spaced positions along one side wall with the width of the benches being equal to the post spacing to form a modular construction. Each bench has associated with it a respective air handling system for conditioning including a duct which is located partly under the respective bench and a fan in a fan housing at the side wall. From the fan a vertical duct section extends to a flexible tube extending over the bench. An alley is arranged along the opposite wall containing electrical controls mounted in cabinets forming panels for mounting in the span between posts. Air dehumidification, fogging, heating and cooling are provided in the duct under the bench.

  • Patent number: 4643164
    Abstract: A portable stove assembly comprising a support member having a side wall which has at least one opening, a stove for burning liquid fuel which is located within the support member and which includes a fuel reservoir, and an air pressure assembly for pressurizing the fuel reservoir of the stove. The stove includes an inlet fixture for a closure cap and an air pressure assembly includes and elongated connecting tube with a cap at one end for engaging the inlet fixture on the stove and a gas fixture at the opposite end for receiving a portable air pump. The connecting tube is configured to extend through the opening of the support member when the cap is applied to the inlet fixture so that the gas fixture is located outside of the support member.
