Abstract: An electrical connector assembly includes a two piece die-casted conductive shell that is adapted to be clamped onto a shielded electrical connector. The electrical connector may be formed of a dielectric housing with four sidewalls extending between a mating end and a wire receiving end. A plurality of contacts disposed in the housing are adapted to be connected to conductors extending into the wire receiving end of the electrical connector. A stamped and formed conductive shield surrounds at least a portion of the housing sidewalls. The two piece die-casted or molded plastic shell is formed by the mating of two shell portions with a set of screws projecting through one of the shell portions into the other of the shell portions.

Each chip breaker surface has a dual action for breaking chips and also for locating the cutter body on the holder.

Abstract: An automatic true centering steady rest apparatus for a rotating cylindrical workpiece during a machining or grinding operation on the workpiece. The apparatus has an integrally mounted gaging device, for continuously gaging the diameter of a workpiece during a machining or grinding operation. A pair of gripper arms are slidably mounted on an operator body in a housing. Each gripper arm and the operator body carries a workpiece contact member engageable with the perimeter of the workpiece. The gripper arms are urged to grip a workpiece by the action of a pair of rollers and two sets of fixed guide pins which are operatively engageable with camming contours contained on opposing inner surfaces of the apparatus housing. The improved efficiency of the apparatus, as a result of the roller and guide pin action allows for placing the gaging device remotely from the workpiece, without any loss in the precision of its measurement.

Abstract: The present invention provides a wire helm in which a coil of electric wire within the bezel of the helm is contained by a wire coil retainer and a backer plate. The backer plate is mounted on the wheel shaft and rotates therewith, whereas the retainer is mounted in fixed relation to the dashboard. One end of the wire coil is connected to the dash through a hole or slot in the retainer, while the other end of the wire runs along a slot in the shaft to connections of the wheel. As the wheel turns in one direction, the wire coil tightens, whereas when the wheel turns in the opposite direction, the coil partially unwinds. In another aspect of the invention, there is provided a bezel which itself contains the wire coil. A bezel-mounted bottom backer plate serves as a barrier to keep the coil within the bezel. A first end of the wire runs along the shaft to the wheel, and a second end is connected to the dash through an opening in the plate.

Abstract: An electrical connector of extreme simplicity for coupling leads of a fetal scalp electrode to a cable of an electrical signal monitor. The connector includes a plurality of electrically isolated wiring frame components derived from a single wiring frame and thereafter insert molded into a connector body. The wiring frame components include a pair of signal pathways passing through the connector body to couple each lead of the fetal electrode to a corresponding conductor in the cable and a reference pathway through the connector body for effecting an electrical reference coupling with the body of the patient and communicating a reference voltage through the cable to the monitor. Integrally formed on the connector body is a pivotable lead retention wing and thereon a lead retention stub. By pivoting the retention wing into a position adjacent to the connector body, the retention stub along with a lead of the fetal scalp electrode is received and clamped into a lead retention recess.
