    Abstract: Cans rolling on a track are inspected by photoelectric means for the presence or absence of a circumferential marking band, and in accordance with the sensing made, are either permitted to continue rolling on the track, or are dropped through to a lower track. To carry out the drop, the upper track is formed with a number of discrete segments displaceable outboardly, the upstream pair of segments being operated by electromagnets under the control of the inspection means to initiate the drop, and the upstream sides of the segments having cam surfaces engageable by a can that has already begun to drop to cause full displacement of the segment and a continuation of the drop. Each segment is shorter than the radius of a can so that it closes in behind a dropping can before the next following can arrives.

    Abstract translation: 在轨道上滚动的罐子通过光电装置检查是否存在圆周标记带，并且根据所做的感测，被允许在轨道上继续滚动，或者被下落到下轨道。 为了执行液滴，上轨道形成有多个离散的外部片段，可以在检测装置的控制下由电磁体操作上游的一对段，以启动液滴，并且具有凸轮的段的上游侧 表面可以由已经开始下降以引起段的完全移位并且延续下降的罐可接合。 每个段都比一个罐的半径短，这样在下一个可以到达之前它就可以在一个掉落的罐子的后面关闭。

    Abstract: D R A W I N G
    APPARATUS FOR GENERATING A SEISMIC SIGNAL IN A FLUID MEDIUM WHEREIN A MEMBER SUCH AS A FLEXIBLE DIAPHRAGM, INFLATABLE ELASTIC MEMBER, PISTON, ETC., IS PLACED IN A FIRST OR INITIAL POSITION RELATIVELY SLOWLY BY A PNEUMATIC, HYDRAULIC, ELECTRICAL, MECHANICAL ETC., SYSTEM, AND UPON FIRING IS ALLOWED TO MOVE RAPIDLY TO A SECOND POSITION, WHERE IT IS ABRUPTLY STOPPED. THAT IS, THE MEMBER PROVIDES FOR THE SLOW CREATION OF A SELECTED VOLUME WITHIN THE FLUID MEDIUM WHICH VOLUME IS THEN ALLOWED TO SHRINK RAPIDLY WHEREUPON ITS MOTION IS SUDDENLY ARRESTED. THE HYDROSTATIC PRESSURE OF THE FLUID MEDIUM CAUSES THE MEDIUM TO FOLLOW THE MOVEMENT OF THE MEMBER, WHEREBY ABRUPTLY STOPPING THE MEMBER LIKEWISE SUDDENLY STOPS THE FLUID MOVEMENT TO GENERATE, IN TURN, A SINGLE HIGH PRESSURE PULSE DUE TO THE WATER-HAMMER EFFECT. THUS, THE INVENTION IS CONCERNED WITH GENERATING A SINGLE SEISMIC PULSE BY THE MORE EFFICIENT PROCESS OF SUDDENLY STOPPING, RATHER THAN BY SUDDENLY ACCELERATING, A GIVEN QUANTITY OF THE SURROUNDING FLUID MEDIUM.

    Abstract: The two mediately positioned cantilevered rings of four spaced concentric rings of resilient spring material are joined to adjacent rings at diametrically opposite locations by resilient bridges to form a leaf spring structure having inner and outer support rings bridged to respective anchor sides of adjacent inner and outer mediately positioned cantilevered rings whose free ends are joined by a resilient bridge. In one embodiment the inner and outer rings are mounted respectively by a slipring assembly to the fixed reference and the suspended inertial mass to allow relative rotation between each of them and the leaf spring structure when subjected to tortuous forces.
