1,123,997. Testing hollow-ware for leaks. ELCALOR A. G. FABRIK FUR ELEKTROTHERMISCHE APPARATE. March 10, 1967 [April 15, 1966], No. 11338/67. Heading G1S. In apparatus for serial testing hollow bodies open at one end for leaks, the bodies 1, e.g. plastic cups, are clamped between circular rotatable flanges 4, 5 the open-end being closed by a diaphragm 11 the lower side of which mounts a displacement body 10, and from the upper side of which extends, a spring-loaded push rod 9. The bottom of the body 1 is supported by the head 7 of a spring-loaded push rod 6. The opposing furthermost ends of the push rods 6, 9 are provided with rollers which engage, on rotation of the flanges 4, 5, cam surfaces 21, 24, respectively such that the push rods 6, 9 and consequently the displacement body 10 and the body 1 are moved through a series of relative positions 1-18, as shown in Figs. 2a, 2b. At positions 9 and 17, in the case of a leaking body the pressure inside the space 49 between the two bodies is reduced to allow the body 1 to be released and carried away along guides 27, 28 respectively. In a modification, e.g. for use with a bottle 51, (see Fig. 4), the bottle 51 is enclosed in a casing body 61, sealed at 71, and a variable pressure is exerted on the space 49a between the body 51 and the casing 61 through a channel 64, the end of which is closed by a flexible diaphragm 11a which is connected to a spring-loaded push rod 9a mounting a roller 23a at its other end to run along cam surface 24a.

FABRIK FUR ELEKTROTHERMISCHE装置。 1967年3月10日[1966年4月15日],编号11338/67。标题G1S。在用于串行测试的设备中,空心体的一端开口以泄漏,例如空心体1。塑料杯被夹持在圆形可旋转的凸缘4、5之间,其开口端由隔膜11封闭,隔膜11的下侧安装有位移体10,并且从隔膜的上侧延伸有弹簧加载的推杆9。主体1的底部由弹簧加载的推杆6的头部7支撑。推杆6、9的相对的最远端设有滚子,这些滚子在凸缘4、5的旋转时与凸轮表面接合分别如图21、24所示,使得推杆6、9以及因此位移体10和体1移动通过一系列相对位置1-18,如图11和24所示。 2a,2b。在主体9泄漏的情况下,在位置9和17处,两个主体之间的空间49内部的压力减小,以允许主体1被释放并且分别沿着引导件27、28被带走。在修改中,例如为了与瓶子51一起使用(见图4),瓶子51被封闭在外壳主体61中,在71处密封,并且可变的压力通过通道施加在主体51和外壳61之间的空间49a上。如图64所示,其端部由挠性膜片11a封闭,该挠性膜片11a连接至弹簧加载的推杆9a,推杆9a的另一端安装有滚子23a,以沿凸轮表面24a延伸。
