Patent IN-2014DE00965-A (IN)
Inventor: WOLF MARCO
IPC: G01B7/00
Filed: 2014-04-02
Abstract: The invention relates to an improved contactless position sensor and a system incorporating same. Such a contactless position sensor comprises at least two sensor coils each comprising a magnetic permeable core and windings defining a coil axis. The at least two sensor coils are arranged with the coil axes essentially in parallel to each other. An electrical circuit of the sensor drives a predetermined alternating current within each of the at least two sensor coils and determines a high frequency voltage component of a voltage across each of the at least two sensor coils. The predetermined alternating current includes a low frequency current component, and a high frequency current component. The electrical circuit detects the position of a ferromagnetic target by subtracting from each other amplitude levels of the high frequency voltage components of two of the determined voltages and by comparing the subtraction result to a pre-determined reference pattern.

IPC: A01F15/04
Filed: 1983-04-22
Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.

Abstract: A pipe wrenching tool adapted to be powered by a hand held power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversely to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted at both sides to have the drive source attached at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate with respect to the pipe.
