摘要： A magnetic signal pickup mechanism is presented. The mechanism comprises a moving magnetic element mass fixedly coupled to a moving element mass such as a nutator. A movable magnetic element wire is physically non rigidly coupled magnetically to the moving magnetic element mass and further coupled mechanically to quasi restrictive longitudinal pivot points wherein the pivot points restrain longitudinal movement in relation to the moving magnetic element mass, the pivot points being offset sufficiently distant from each other to prevent contact between the wire and any structure other than the pivot points, wherein the wire is non straight.

摘要： A centrifugal positive displacement device is presented. It is believed that this is the first type device which has the advantages of both a centrifugal pump and a positive displacement pump without any substantial disadvantages. The device comprises a casing similar to that of previous centrifugal casings disposed around an impeller smaller than prior art centrifugal impellers and having cavities in the outer surface thereof. On each side of each cavity is coupled a flexible loop. In operation, as it passes the cam, the flexible loop is filled with incoming fluid which is then compressed out as the cam is approached near the discharge port.

摘要： An off center one spot nutator fulcrum rocking bearing assembly is presented. The assembly comprises a non rotating circular cylindrical fulcrum rod coupled at each end to a selected fixed point inside a nutating pump chamber. An off center non rotating rocking nutator fulcrum bearing has an interior circular cylindrical surface rotatably mating with and coupled around the exterior circular cylindrical surface of the rod, the bearing having at least two exterior surfaces parallel to the bearing axis including a first generally planar bearing surface parallel to the bearing axis and disposed closer to the bearing interior surface than any other bearing exterior surface parallel to said axis wherein said first bearing surface slideably nutatably couples to a nutator barrier, whereby the barrier rides on the first bearing surface during nutation causing the bearing to rock.

摘要： A visually and mechanically testable float switch composite is presented. The composite had a casing having one opening into a switch cavity containing a switch having leads potted to the outside. A float is coupled through the opening by coupling means to mechanically actuate the switch. The opening is closed by a bearing and bearing cap surrounded by and sealed by an elastomeric boot. Closing of the cap increases pressure on the fluid in the switch cavity thereby causing the boot to expand like a balloon thereby permitting visual or mechanical testing since the boot remains expanded if there is no leak. In like manner, any submersible component may be made visually and mechanically testable by inserting a cap thereby increasing the internal pressure and monitoring a balloon like expandable boot to determine whether the increase in pressure is maintained.
摘要翻译：提出了一种视觉和机械可测试的浮子开关复合材料。复合材料具有一个壳体，该壳体具有一开口，该开口包含一开口，该开关具有封闭到外部的引线。浮子通过连接装置通过开口联接以机械地致动开关。开口由被弹性体衬套包围和密封的轴承和轴承盖封闭。盖的关闭增加了开关腔中的流体的压力，从而使得靴子像气囊一样膨胀，从而允许视觉或机械测试，因为如果没有泄漏，则靴子保持膨胀。以类似的方式，任何潜水部件可以通过插入盖而进行视觉和机械测试，从而增加内部压力并监视气囊如可膨胀的靴子，以确定压力的增加是否保持。

摘要： A magnetic signal pickup mechanism is presented. The mechanism comprises an orbiting mass fixedly coupled to a cyclically repetitively moving element which by moving through its cycle causes the mass to orbit. A relatively tight but slightly moveable wire is coupled to selected points at each end so as to pass near at least one part of the orbit of the mass. One of the mass and the wire is ferro magnetic and the other of the mass and the wire is a permanent magnet sufficiently powerful so that the wire moves one cycle in an orbit in response to each orbit of the mass. A signal detector is coupled to the wire to count orbits of the wire.
