Title: Folding four pack carton
Inventor: CLEIN ALLEN W
IPC: B65D71/58
Filed: 1991-06-24
Abstract: ABSTRACT          A paperboard carton having an improved locking bottom.  The disclosed carton has a collapsed position and an expanded position.  In its expanded position, it has a square flat bottom which includes four flaps.  A first pair of floor flaps, foldably attached along the bottom edges of opposite sidewalls have tabs which interlock when the carton is in the expanded postion.  The second pair of floor flaps, foldably attached along the bottom edges of the remaining opposite sidewalls,  are relatively large and overlie the first pair of flaps and overlap each other when the carton is in the expanded position.  Each of the first pair of floor flaps is divided into two sections by a foldline which extends from a corner of the expanded carton.  For each such flap, there is a first section, adjacent one of the remaining pair of floor flaps and glued to its underside so that the floor flaps are sandwiched up between the sidewalls of the collapsed carton and such that when the carton is unfolded from its collapsed to expanded position, the floor flaps unfold synchronously.  The interlocking tabs have edges located to abut each other as the flaps of the expanded carton are forced out of their flat position.  The abutment thus tends to hold the carton floor and sidewalls in the expanded position.  The floor flaps are shaped to ensure that as the carton is unfolded each non-interlocking floor flap unfolds to overlie the neighboring flap to which it is not glued. The carton sidewalls also have upper portions defined above horizontal cuts in the sidewalls, which portions fold inwardly from corners of the carton towards the center of the carton to form upwardly open bottle receiving compartments.  Apertures in the upper portions provide handles for carrying the carton.

Two separate mutually independent but interacting absorption cooling devices are provided, the cooling system of one of the two devices being used for cooling the absorbent liquid of the other device, this liquid, after dilution by the fact of having absorbed steam, being boiled by heat provided by condensing steam resulting from boiling the diluted absorbent liquid of the initially considered absorption device by means of an external burner. The pressure in each component of the absorption device used for directly cooling the air is less than the pressure in the corresponding component of the other device, the absorbent liquid of which is cooled by external cooling fluid. <IMAGE>

Title: Process for destroying harmful species of woody plants by high pressure water jetting
Inventor: GUEST FRANK
IPC: A01M21/00
Filed: 1992-04-16
Abstract: ABSTRACT       A high pressure water pumping unit consists of a long stroke piston pump capable of producing pressures of 10 000 P.S.I. to 30 000 P.S.I., when driven by a motor capable of producing 50 to 200 H.P.    When the water under pressure of 30 000 P.S.I. is directed via high pressure hose to a high pressure gun fitted with a hardened stainless steel nozzle with an opening of 1/32 of an inch or smaller, the resulting stream of water is capable of cutting very hard materials such as stone or steel.  When this stream of water is directed at the base of a woody plant it may cut through the soil and the woody material of the target plant.  The stream of water may cut through the soil, disturbing it very little except to cut the soil to the same width as the stream of water and to cut the woody material of the target plant below the level of the ground.
