    • A peritrochoid curved surface generating apparatus comprises an outer cylinder rotatably supported on a frame, a first central shaft rotatably journalled in the rotating axis of the outer cylinder, an inner cylinder adjustably fixed within an eccentric opening of the outer cylinder, an inner cylinder central shaft rotatably journalled in an axis of the inner cylinder, a second central shaft rotatably journalled in an eccentric opening of the inner cylinder and supporting a work table, a gear train for transmitting the rotation of the first central shaft to the second central shaft through the inner cylinder central shaft, a cylindrical tool rotatable about its axis and a rocking device supporting the tool and rockable in synchronism with the rotation of the outer cylinder. A distance between the first and second shafts is adjustable and a rocking angle of the rocking device is also adjustable, so that the apparatus can be used for generating various peritrochoid curved surfaces different in configuration without any interference between a tool and a workpiece.

    • An air diffuser (2) having a diffuser tube (5) immersed sidewardly in a tank (1), a flushing pipe (9) opening at its tip an outlet (11) at an upper position of the diffuser tube, and a flushing valve (12) disposed in the flushing pipe (9). The diffuser tube (5) is made up of a main pipe (6) communicated at its basal end to an air supply source (8) and communicated at its tip to the flushing pipe (9), and a plurality of branch pipes (7) being communicated to the main pipe (6) and opening at their tip as a blowhole (10) at a lower position of the main pipe (6). During air diffusion, air is supplied from the air supply source (8) with tile flushing valve (12) closed, and the air is diffused from the blowholes (10). During flushing, air is supplied from the air supply source (8) with the flushing valve (12) opened and an intra-tank mixed liquor is sucked from the openings of the diffuser tube (5), thereby flushing the inside of the diffuser tube (5) with the sucked intra-tank mixed liquor. The intra-tank mixed liquor is then joined with air to come off together from the outlet (11) of the flushing pipe (9). Air diffusion from the blowholes (10) and the flushing of the diffuser tube (5) are alternately repeated by utilizing pulsation to be caused by pressure variations in the diffuser tube (5).
    • 1.一种空气扩散器(2),其具有浸在罐(1)的侧面的扩散管(5),在其顶端处在扩散管的上部位置处的出口(11)的冲洗管(9)和冲洗阀 (12)设置在冲洗管(9)中。 扩散管(5)由其基端与空气供应源(8)连通并在其顶端连通到冲洗管(9)的主管(6)和多个支管(7) )在主管(6)的下部位置处被连通到主管(6)并在其尖端处作为气孔(10)打开。 在空气扩散期间,空气从空气供应源(8)供应,瓦片冲洗阀(12)关闭,空气从气孔(10)扩散。 在冲洗期间,空气从空气供应源(8)供应,冲洗阀(12)打开,并且从扩散管(5)的开口吸入槽内混合液体,从而冲洗扩散管内部 (5)与吸入的罐内混合液。 然后将箱内混合液与空气接合,从冲洗管(9)的出口(11)一起脱出。 通过利用由扩散管(5)中的压力变化引起的脉动来交替重复来自气孔(10)的空气扩散和扩散管(5)的冲洗。
