Abstract: A method of treating external hemorrhoids comprises the preliminary and optional step of rubber band ligation of any associated internal hemorrhoidal tissue, followed by a laser beam-created incision around the perimeter of the base of the external portion. The surface of the external portion is then evaporated with a traversing movement of the laser beam. The laser beam is then employed to form a cavity into the core of the hemorrhoid, dimensioned to accommodate the subsequent insertion of a cryogenic probe, which freezes the hemorrhoidal tissue from the interior outwardly.

Abstract: A green sand mold filling system is formed of an air chamber box having a cover plate which supports a pattern. Air passageway holes, which communicate with the air chamber, extend through the plate and pattern at preselected locations, such as difficult to fill pockets, depressions and the like. An open top and bottom flask section is positioned over the plate and around the pattern. Filling sand is poured into the flask and is mechanically compacted or squeezed therein. During the filling and squeezing, a vacuum is provided in the air chamber and, therefore, through the air passageway holes, to assist the sand flow into and the sand densification at the pre-selected locations. Thereafter, the vacuum is discontinued and pressurized air is provided in the air chamber and, therefore, through the air passageway holes, to assist in separation of the compacted sand from the pattern and plate and to maintain the integrity and accuracy of the cavity formed in the sand while the flask section is removed.

Abstract: A method and apparatus for servicing trunked plants such as citrus trees in which water, in heated or unheated form, is delivered by a manifold system to the base of each tree, conducted upwardly in a hose helically upwardly encircling the tree to a collar encircling the tree at an intermediate location on the trunk, and discharged from a plurality of circumferentially spaced openings in the collar and allowed to flow by gravity back down the trunk. In unheated form, the water irrigates and nourishes the tree trunk. In heated form, the water warms the tree trunk and protects the tree trunk from frost damage. The heated tree trunk and heated water will also heat the air next to the tree trunk. This heated air will rise upward and outward to heat some major branches and foliage beyond the tree trunk area.

Abstract: A diesel engine has a cylinder head, an auxiliary combustion chamber defined in the cylinder head, an atomization passage communicating with the auxiliary combustion chamber, and a fuel injection nozzle means mounted in the cylinder head and having a primary injection port opening into the auxiliary combustion chamber and a secondary injection port opening toward an inner wall surface of the atomization passage. When the diesel engine is under a low load, fuel is injected from the secondary injection port toward the inner wall surface of the atomization passage while fuel is prevented from being injected from the primary injection port, for thereby causing fuel to flow along an inner wall surface of the auxiliary combustion chamber, which is positioned downstream in the direction in which a swirl flows.
