摘要： A linear gauging head, or cartridge head, comprises a casing, a spindle movable with respect to the casing along a longitudinal axis, a feeler coupled to a first end of the spindle and a differential position transducer with windings, fixed with respect to casing, and a core coupled to a second end of spindle. The spindle is guided by recirculating ball bushings with rolling elements that cooperate with the spindle and thus allow its displacement with respect to the casing.

摘要： A deflection yoke includes a bobbin having a cavity formed in the longitudinal direction of the bobbin, and an adjusting coil having a magnetic core on which a thread is cut. The core inserted into the cavity is slidable in the longitudinal direction of the bobbin. The core has a marker formed on only one of ends of the core in the longitudinal direction. The core has been inserted into the cavity from the one end formed with the marker or the other end. The marker is formed on only one of ends of the core before or after the thread is cut thereon.

摘要： A system for transmitting data through a string of down-hole components. In accordance with one aspect, the system includes a plurality of downhole components, such as sections of pipe in a drill string. Each downhole component includes a pin end and a box end, with the pin end of one downhole component being adapted to be connected to the box end of another. Each pin end includes external threads and an internal pin face distal to the external threads. Each box end includes an internal shoulder face with internal threads distal to the internal shoulder face. The internal pin face and the internal shoulder face are aligned with and proximate each other when the pin end of the one component is threaded into a box end of the other component.

摘要： The arrangement includes a transformer whose primary winding and secondary winding are in separate pot cores which can rotate in opposite directions about the axis of rotation of the steering wheel. To prevent these transformers from transferring energy to the squib which could deploy the air bag when a short-circuit to lines carrying on-board voltage occurs on its primary side, only one of the two pot cores is designed as a closed ring and the other pot core is made of one or more ring segments.

摘要： A system for transmitting data through a string of downhole components. In one aspect, the system includes first and second magnetically conductive, electrically insulating elements at both ends of the component. Each element includes a first U-shaped trough with a bottom, first and second sides and an opening between the two sides. Electrically conducting coils are located in each trough. An electrical conductor connects the coils in each component. In operation, a varying current applied to a first coil in one component generates a varying magnetic field in the first magnetically conductive, electrically insulating element, which varying magnetic field is conducted to and thereby produces a varying magnetic field in the second magnetically conductive, electrically insulating element of a connected component, which magnetic field thereby generates a varying electrical current in the second coil in the connected component.

摘要： A variable inductance transformer includes a core defining a gap between opposing first and second ends. A primary winding and at least one secondary winding are coupled to the core. The secondary winding is provided for stepping up the voltage across the primary winding. A carriage assembly includes a magnetic shunt movable against the core and variably across the gap. The magnetic shunt has a width at least as wide as the gap for moving the shunt to a predetermined position along the core in a range from an uncovered position not overhanging the gap, throught intermediate positions overhanging the gap, to a covered position where the shunt bridges the gap. A control circuit controllably energized a motor to move the carrriage assembly and position the magnetic shunt against the core for adjustably varying the inductance of the secondary winding a to maintain a high output voltage of the transformer for a given resistive supply current.
