    • A C-shaped tree and plant watering pail which can be fitted around a plant stem or the trunk of a tree and holds water which is slowly released into the soil through a porous bottom section. A removable flexible cover can be placed over the porous bottom section to allow the pail to retain its water. In a preferred embodiment the pail has a water reservoir between two concentric side walls with a hollow center section and a vertical slice missing from the pail walls which gives it a C-shape as viewed from above or below. In another embodiment a section is removed from the top of the C-shaped reservoir leaving the missing vertical slice extend from the bottom up only part way to the top.
    • 一个C形树木和植物浇水桶,可以安装在植物茎或树干上,并保持通过多孔底部部分缓慢释放到土壤中的水。 可移动的柔性盖可以放置在多孔底部部分上,以允许桶保持其水。 在一个优选实施例中,桶具有两个同心侧壁之间的储水器,其具有中空中心部分,并且从桶壁缺失垂直切片,其从上方或下方观察其呈C形。 在另一个实施例中,从C形容器的顶部移除截面,留下的垂直切片从底部向上仅部分延伸到顶部。

    • A heat treating furnace having a quenching chamber incorporated therein or associated therewith is disclosed. The heating chamber within the furnace is utilized to heat work-pieces to a desired temperature. When the heating cycle has been completed, the heating chamber and the quenching chamber are back-filled with an inert gas to a redundant pressure (over atmospheric). The work-pieces are then transferred into the quenching chamber and lowered into the intensively agitated water in the water quench tank by an elevator mechanism. High quenchant (water) agitation rates eliminate film boiling on the surface of the hot work-pieces. When the compressive stresses on the surface of the work-pieces are at a maximum and are at an optimum depth, or when the cooling recipes otherwise determine, the elevator mechanism in the quenching chamber lifts the work-pieces out of the water quench tank and into the inert gas blanket above the tank, thus interrupting the intensive quenching process. The cores of the work-pieces are then allowed to cool uniformly by conduction through their intensively quenched outer shells. After cooling, the work-pieces, having both high hardness and low distortion, are removed from the quenching chamber.
    • 公开了一种具有结合在其中或与其相关联的淬火室的热处理炉。 炉内的加热室用于将工件加热到所需的温度。 当加热循环完成时,加热室和淬火室用惰性气体填充至多余的压力(大气压)。 然后将工件转移到淬火室中,并通过电梯机构下降到水骤冷箱中的剧烈搅动的水中。 高淬火(水)搅拌速​​率消除了热工件表面的薄膜沸腾。 当工件表面上的压应力处于最大并且处于最佳深度时,或者当冷却配方另外确定时,淬火室中的电梯机构将工件提升出水骤冷箱, 进入罐上方的惰性气体保护层,从而中断了强烈的淬火过程。 然后通过其强烈淬火的外壳通过传导使工件的芯体均匀地冷却。 冷却后,从淬火室中除去高硬度,低变形的工件。

    • A shaft guard is provided comprising a first guard portion, a second guard portion, and a pair of support legs. The first guard portion defines a first guard body, a first pair of guard portions, and a first pair of flange portions. The first guard body is arranged about a longitudinal shaft guard axis. The first pair of guard portion openings are positioned at opposite ends of the longitudinal shaft guard axis. The first pair of flange portions are arranged on opposite sides of the longitudinal shaft guard axis. Similarly, the second guard portion defines a second guard body, a second pair of guard portions, and a second pair of flange portions. The second guard body is arranged about the longitudinal shaft guard axis. The second pair of guard portion openings are positioned at opposite ends of the longitudinal shaft guard axis. The second pair of flange portions are arranged on opposite sides of the longitudinal shaft guard axis. Respective ones of the first pair of flange portions are secured to opposing ones of the second pair of flange portions to form respective mated flange pairs such that the respective ones of the first pair of guard portion openings complement opposing ones of the second pair of guard portion openings to form a pair of shaft guard openings positioned at opposite ends of the longitudinal shaft guard axis. The pair of support legs are secured to at least one of the first and second guard portions.
