Abstract: PINCH VALVE                    ABSTRACT OF THE DISCLOSURE             A pinch valve for throttling or terminating the flow of a fluid through a pipe or the like.  The valve features two cam bodies within an extension of the valve body.  An inner cam body is cammed into non-rotational translational movement in a direction towards and away from the flexible and resilient sleeve of the pinch valve by the cam surface of an outer cam body of circular cross-section which is at least partially rotatable by displacement of a turn handle.  The handle may be partially turned about the axis of the outer cam body, to partially constrict or throttle fluid flow, or further turned to completely pinch the sleeve shut and totally terminate fluid flow.

Abstract: SOLIDS DIVERTER FOR A DOWNHOLE DRILLING MOTOR Abstract of the Disclosure A downhole drilling motor located near the end of a rotary drill string is operated by the drilling mud for driving a rotary drill bit to drill an oil or gas well or the like.  Fluid lubricated bearings are employed and a portion of the drilling fluid is diverted through the bearings of the downhole motor with the balance of the drilling fluid being discharged through ports of the drill bit.  The diverted portion of the drilling fluid is transmitted along a flow path that results in an abrupt change of direction of flow.  The flow path will purge a portion of the drilling fluid of unwanted solids by diverting the solid along with the main portion of the drilling fluid through the motor and through and out of the drill bit.  The entry of large contaminating solids or high-density and abrasive solids to the bearings is restricted.  This prevents plugging of flow through the bearings and reduces wear in the bearings by reducing the volume of abrasive solids.

Abstract: ABSTRACT OF THE DISCLOSURE    In the method of producing photoelectric transducers which method having processes for forming a photoconductive layer on a predetermined substrate which has an irregular surface.  The method includes depositing the photoconductive layer in an atmosphere including at least plasma, the pre-determined substrate with irregular surface being disposed above a first electrode to which an electrode is opposed, and said photoconductive layer is formed while a negative potential is applied to the first electrode.  This enables the photoconductive layer to be formed without breaks or steps, pinholes and so on due to the irregular surface, and therefore, it is possible to provide good photoelectric transducers having a small dark current.

The motor is a standard motor having special caps at each end of the motor shell and with the shell forming a waterproof en-closure.  The caps have radially extending spacers extending out to the pipe.  At each end of the pipe are reducers, the internal diameter of the small ends of which correspond to the external diameter of another, smaller standard pipe size.  At the bottom a piece of pipe of the smaller size extends inwardly of the reducer to a location in juxtaposition to the pump im-peller.  Various connections and mounting arrangements may be made using standard sizes of pipe.  In one embodiment the pump is mounted on a vertical track and positioned above a sump.  When the water rises to a level in the sump at which pumping should commence, the motor is energized and the pump is lowered along the track into the sump.
