Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE            An  electrode  assembly  for  sensing  heart  activity  and especially heart activity from a fetal epidermis during the birth of a child.  A fetal electrode introducer includes a rigid guide tube with an intermediate universal joint which allows the guide tube to be bent at the best angle to accommodate each patient.  The intermediate joint allows a smooth transmission of the rotary motion manually applied at a distal handle to drive the electrode into the fetal epidermis.            A sliding sleeve covers the fetal electrode to provide a bearing for rotation, protects the electrode from contami-nation, and also serves as a resistance means to indicate to the user that the assembly has abutted against the fetal epidermis.  Such resisting means includes either a detent or lockable system, or a breakable membrane.

Title: Apparatus for retaining axial movement relative to a cylindrical housing
Inventor: RINGGENBERG PAUL D
IPC: E21B23/00
Filed: 1988-07-19
Granted: 1992-01-14
Abstract: Abstract Apparatus for retaining axial mandrel movement relative to a cylindrical housing.  A cylindrical housing has an open longitudinal passageway therethrough and a circulation port disposed through a wall thereof.  A valve mandrel is sli-dably received in the housing and is moveable between a position in which fluid may be circulated only between the passageway and the exterior of the housing, a position in which fluid may be circulated only between the exterior of the housing and the passageway and a position in which fluid may not be circulated in either direction.  An annular piston is operatively connected to the valve mandrel and has a first side exposed to the pressure exterior of the housing and a second side exposure to the pressure interior of the housing to permit movement of the valve mandrel to its various positions by application of pressure to the interior and exterior of the housing.  A substantially cylindrical spring includes a plurality of elongate fingers disposed about the circumference of a splined mandrel to which the valve mandrel is connected.  The spring includes a substan-tially arcuate collar formed about the radially inner sur-face thereof which is engagable with different grooves in the splined mandrel in order to retain the valve mandrel in preselected positions.  A pressure differential of a prede-termined value between the annulus and the passageway is required to bow the spring fingers radially outwardly thereby enabling mandrel movement while preventing mandrel movement in response to low pressure pump surges and low pressure differentials generated by movement of the pipe string on which the tool is suspended.
