Abstract: A method and apparatus is provided for calibrating distance measuring instruments, in particular, optical three dimensional measurement sensors. The method is not restricted to aligning the motion of the calibrating surface to be parallel to the sensor centerline. Accordingly more than one sensor can be present during the calibration procedure. This leads to the practicality of aligning multiple sensor systems using a common translation stage for all sensors or using translation stages that are a part of the system. The joint calibration of sensors embedded in a system guarantees proper registration without additional steps. A method for calibrating optical sensors to accuracies approaching the wavelength of light is given.

Abstract: A lampholder, for mounting a lamp in an opening of a reflector in a headlight for an automotive vehicle, includes a ring having structure for mounting the ring in the reflector opening and locating elements for locating the lamp in the ring in a position which is predetermined both axially of the lamp and rotationally around the lamp axis. The lamp holder also has structure whereby the lamp can be secured removably in this position. This securing structure includes a radially extending tongue and a locking finger diametrically opposite the tongue, both being formed integrally with the lampholder ring. The tongue is hinged on the ring and has a longitudinal profile such that, when it is swung about its hinge so as to overlie a diameter of the ring, it covers a part of the lamp and is held in position by the locking finger. In this position the tongue is resiliently deformed so as to exert a spring biassing force on the lamp and thus to hold the latter firmly in position.

Abstract: A flow cell is utilized on-line in the analysis of molten polymer and includes diamond windows for passing mid to far infrared radiation through the molten polymer flowing through the flow cell, the diamond windows being in the form of relatively thin disk-like elements each affixed to a carrier member in the wall of the flow cell and spanning a relatively large diameter bore in the carrier member, the overall diameter of each disk-like element being only slightly greater than the corresponding bore in the carrier member such that the volume of diamond is minimized in relation to the diameter of the windows.

Abstract: Leak detector arrangement for the detection of small openings in car bodies or other enclosures or containers which may permit undesired passage of water, fumes, or other fluids in which phase coded or linearly frequency modulated sound waves are directed towards potential leak areas. The portion of these waves which pass through the leak openings is received, and these signals are processed so as to discriminate these leak signals from other sound waves normally entering the receiver from other parts or from other sources. The discriminated signals are compared with a threshold so as to determine the absence or presence of a leak.

Abstract: The invention provides a mechanism for retaining a bulb in position in a lamp holder of a reflector. The lamp holder comprises a circulat bearing surface for engagement by the flange of a bulb, and the mechanism comprises a spring clip pivotally mounted on one side of the lamp holder and having cranked legs adapted to bear against the bulb flange. The spring clip is adapted to engage a catch element on the opposite side of the lamp holder which comprises a lamp engageable by the end of the spring clip, which terminates in a catch. The catch element also incorporates a release ramp facing the catch. On fitting of the bulb, pressure on the spring clip towards the opening causes the clip to side over the ramp and engage the catch, thereby to secure the bulb. Removal of the bulb is acheived by pressure on the spring clip in the same direction, which causes the clip to slide over the release ramp and pass out of the catch element, thereby releasing the bulb.

Abstract: A universally adjustable telescopic spectacle assembly for use with an implanted intraocular lens employs an objective lens which has positioned in front of the objective lens a cylindrical lens to provide cylindrical correction to the handicapped user. The telescopic assembly employs universal motion in that the assembly can be moved with respect to a spectacle frame so that one is able to shift the objective lens axis about a central point while further having the capability of moving the objective lens in a spiral motion away from or towards the eye of the user and further having means for providing a pivotal joint mechanism to permit maximum oblique adjustment of the entire telescopic assembly as related to the optical or central axis of the objective lens. In this manner any change in conditions of vision or a misalignment of the intraocular lens as inserted during surgery can be compensated for by the universal adjustable telescopic assembly as disclosed.

The power source accommodating section includes a source of illumination and cylindrical condensing lenses which operate to condense the light pattern from the illumination source and to change the light pattern from an elliptical to a circular pattern to thereby uniformly illuminate the text or material to be viewed via the magnifying lens assembly.

Abstract: A pressure profile versus flow rate is determined for a flow control system using positive displacement or a flow meter to measure flow. The profile is used as a pressure reference for closed loop pressure control of flow during the transient period following a change in commanded flow rate to reduce the time required to reach the new flow rate with compressible fluids and compliant output lines. Alternatively the pressure profile is automatically determined and updated continuously to adapt to environmental conditions affecting the accuracy of pressure controlled fluid flow.
