摘要:
The invention concerns a rotational angle measuring arrangement for measuring angle dependent units of an encoding shaft which is journaled in a transducer housing. A stator coupling non-rotationally connects the transducer housing to the housing of a drive system that is to be measured, and the encoding shaft and a drive shaft of the drive system are non-rotatably secured to each other. To provide an improved angle measuring system when the stator coupling is positioned between the transducer housing and the drive housing, to prevent angle measurement errors and to facilitate the mounting of the transducer, at least one locking mechanism is provided. When the transducer, including the stator coupling, is detached from the drive housing, the locking mechanism causes the stator coupling to non-rotatably lock the encoding shaft to the transducer housing, and when the stator coupling is secured to the drive system, the locking mechanism permits the encoder shaft to freely rotate.

Apparatus for use in aligning the differential input shaft of a race car with the transmission output shaft includes a transmission attachment and a differential attachment, each of which is detachably mountable to the race car. Each attachment includes a laser mounted centrally in a plate which is mounted substantially perpendicular to the transmission and the differential respectively. The laser mounted to the transmission emits a light beam coaxial to the transmission output shaft and the laser mounted to the differential emits a light beam coaxial to the differential input shaft. By adjusting the differential and transmission relative to each other such that the laser beams do not intersect, the differential and the transmission are aligned for optimum performance. A camber gauge may be substituted for the laser in either plate to measure the attitude of the differential or the transmission.

A layout tool for laying out or “marking” positions at a predetermined spacing for the attachment of studs having a nominal thickness to a length of dimensioned lumber comprising a plate, when framing walls during construction of a building. The layout tool includes an elongated rail for placement against the plate, and a first stud marking guide extending perpendicularly from the elongated rail. The first stud marking guide has left and right side edges, and width between the side edges corresponding to the nominal thickness of the studs. A separate stud marking guide extends perpendicularly from the elongated rail. The second stud marking guide likewise has left and right side edges and a width between the side edges corresponding to the nominal thickness of the studs. The left edge of the second stud marking guide is spaced from the left edge of the first stud marking guide a distance equal to the predetermined stud spacing. A primary starter marking indication is provided on the elongated rail intermediate the first and second stud marking guides. The primary starter marking indication is spaced from the second stud marking guide a distance equal to one-half the nominal thickness of the studs.

The present invention comprises an improved ultrasonic transducer mount including a removable union sleeve engaged with a transducer holder sleeve on the mount. The union sleeve has an outer diameter that engages an extractor tool for removal of the transducer and transducer holder from the mount. A retaining ring holds the union sleeve in place on the outside of the transducer holder sleeve.

The tool for locating a center mark for embroidery on articles such as garments includes a planar body having orthogonally-related legs with respective exterior and interior edges. Index markings are provided on the legs along the linear edges. The index markings include indicia identifying a plurality of corresponding preestablished garment sizes along the linear extending edges, respectively. By aligning common selected sizes along the edges with the vertical centerline of a folded garment and a shoulder portion of the garment, respectively, the location of the embroiderer's center mark on the garment is identified at the intersection of the linear edges. The interior edges of the tool may also used to form marking lines where conventional hoop grids are not available.

A locating device for locating a body such as an electrical box behind a wall or ceiling. The device includes a first member positionable in the body and a second member that can be positioned on the outer surface of the wall or ceiling. A magnet positioned in the first member cooperates with a magnet positioned in the second member to maintain the second member in an aligned position with respect to the electrical box. Two magnets can be used to enhance the alignment of the second member with the electrical box. A circular first member can be used for locating circular boxes or lights. A second member having an arm can be used with a circular first member. The second member can include a plurality of apertures, each aperture sized to correspond to a specific size light or electrical box.

It is a miter saw table that has adjustable measuring tapes. The tape sections can be calibrated so that the zero point on the tape is always set at the outer surface of the blade. This is done by using slidable wings that can be secured to a base. The wings a readjusted until the built-in tapes match a control tape. Once the wings are set, cuts can be made quickly by either setting a stop at the precise distance needed, or by sliding the board under the blade until the end of the board aligns with the desired measurement. The board can then be accurately cut without having to measure and mark the board first. Moreover, if the blade is changed during the course of work. The measuring system can be quickly re-calibrated to the thickness of the new blade and cuts can immediately be resumed.

In order to improve a sensor assembly comprising a sensor which can be fixed in position on a functional unit and has a sensor housing, in which a sensor element with evaluation electronics is arranged, in such a manner that as simple and universal a fixing of the sensor as possible on the functional unit is feasible it is suggested that the sensor assembly comprises a sensor holder which can be brought into a position following the sensor housing in longitudinal direction and can be detachably connected to the sensor housing in this position by means of form-locking elements and that the sensor be fixable on the functional unit by means of the sensor holder.
