| A sensor has a metal case with a sensing coil at one end and a shielded cable extending from the other. In one use it is placed in proximity to rotating machinery to sense imbalance by position change of the shaft. A pair of suitably sized metal cylinders which are precisely interlocked by dielectric material provides for firm mechanical and electrical connections to the inner and outer conductors of the associated shielded cable. In addition a four step injection molding process provides for accurate and secure location of the sensing coil. And at the same time the entire structure because of the injection molding and associated seals is moisture proof. Other uses include temperature and velocity sensing.In an alternative embodiment only a two-step injection molding process is utilized with a somewhat simplified procedure. | ||||||

| 150 | System and method for monitoring torsional vibrations and operating parameters of rotating shafts | US866055 | 1992-04-10 | US5253531A | 1993-10-19 | Dana A. Walker; Michael D. Walker |
| An optical system for monitor vibration, particularly applicable to power shafts in rotating power systems such as those found in trucks, naval vessels, turbogenerators, hydroelectric and nuclear generators, and helicopters, has an optical unit including IRLED radiation sources aimed at grid lines applied around the circumference of the shaft. The reflection of the radiation is imaged through lenses and a matching Ronchi grid onto a photodiode which produces a periodic wave signal from which indications of rotational irregularities can be derived. In one embodiment, duplicate radiation sources and imaging apparatus are arranged in diametric opposition across the shaft to permit compensation for pitch and plunge shaft vibration. In another preferred embodiment, a second, duplicate optical unit is located at a distance along the shaft from the first unit. The output signals of the two units are passed through a comparator and a EX-NOR gate, then low-pass filtered to produce a signal indicative of torsional deflection. Quadrature techniques can be used to provide shaft directional information. Also disclosed are a method and apparatus for precisely applying finely spaced grid lines to an existing shaft on site. A photosensitive material is applied to the shaft, and a strobe light synchronized to the rotation of the shaft exposes the photosensitive material as the shaft is rotated to create finely spaced grid lines on the material. | ||||||

| 155 | Electromagnetic sensor assembly | US317967 | 1989-03-02 | US5006797A | 1991-04-09 | William L. Smith |
| An improved sensor assembly for providing an electrical signal representative of the velocity of a movable body. The assembly includes a sensor for sensing the velocity of the body and providing the signal and a mounting block disposed close to the body for locating the sensor in a predetermined position with respect to the body. The mounting block has a passageway extending through the block for receiving the sensor and for restricting the movement of the sensor along a direction co-existent with respect to the longitudinal axis of the sensor. The sensor itself includes an elongated barrel portion having a sensing tip in one end. The elongated barrel portion includes a shoulder stop located along the elongated barrel portion at a predetermined position from the end of the elongated barrel portion having the sensing tip. The assembly further includes a nosepiece attached to the mounting block which abuts against the shoulder stop of the sensor, thereby restricting the movement of the sensor along the direction co-existent with respect to the longitudinal axis of the sensor to a predetermined position from the body. Thus, once the mounting block has been initially installed, the sensor itself can be replaced without the necessity for recalibrating the sensor assembly. | ||||||
| 156 | Magnetic ring for detecting the rotation of an object | US889139 | 1986-07-23 | US4835505A | 1989-05-30 | Kenji Hattori; Hiroshi Tanaka; Shinichi Tanaka |
| A ring to be attached to a rotating body for producing a magnetic signal in cooperation with a magnetic sensor relative to which the rotating body rotates, comprising: a magnetic ring member having an alternating magnetic property along its circumference consisting of synthetic resin in which magnetic material is dispersed; and a reinforcement ring member which is made of synthetic resin material and substantially surrounds the magnetic ring member. Alternatively, the reinforcement ring may consist of a metallic band which extends the full circumferential surface of the ring. By thus reinforcing the resinous magnetic material, the cost of the ring can be reduced, and the increased mechanical strength of the ring allows easy handling and effective press fitting of the ring. By forming the ring with a plurality of arcuate portions, the stocking and installing of the ring is facilitated. | ||||||

| 160 | Device for photoelectric measurements of moving parts | US231489 | 1972-03-03 | US3961184A | 1976-06-01 | Josef Schurrer |
| Apparatus for photoelectric measurements of a parameter of a movable part such as the rotary speed thereof wherein the part is provided with constrast marks thereon and the light source and the light receiver of the apparatus are not separated by the movable part. The light source and the light receiver are commonly housed in a scanner unit arranged at one end face of a light conductive member, the other end face being positioned proximate to the contrast marks on the movable part such that the light conductive member forms a light beam path for directing light from the light source onto the movable part and for directing reflected light from the movable part to the light receiver. For measurements required within a chamber, the light conductive member extends through a passage in the casing of the chamber which passage may be arranged radially or axially of the chamber and is secured within the passage, which may effect a vacuum-tight seal for vacuum-tight integrity of the chamber, such that the end face carrying the scanner unit is positioned outside of the chamber while the other end face is positioned within the chamber. | ||||||
