Patent GB-2198531-A (GB)
Title: Optical sensor system
Inventor: JONES ROGER EDWARD
IPC: G01L1/18
Filed: 1986-12-13
Abstract: An optical sensor, e.g. a pressure or temperature sensor, includes an optically driven vibrating element 13 whose natural resonant frequency is a function of the parameter to be measured. Detection of vibration is effected interferometrically in optical system 11. Feedback to provide drive of the element and the correct frequency and phase is provided in electronic system 12 via a phase locked loop 37 running at double the vibrational frequency. This prevents loss of phase matching. Typically the frequency doubler comprises a precision full wave rectifier 35 (or a signal squarer). Application is to well-logging, chemical processing or nuclear instrumentation. <IMAGE>
Patent GB-867765-A (GB)
Abstract: 867,765. Rod vibrators. ZENITH RADIO CORPORATION. April 4, 1957 [April 16, 1956; March 11, 1957], No. 30757/59. Divided out of 867,764. Class 13. An ultrasonic generator comprises a plurality of cylindrical rods 201, of which one only is shown, preferably composed of aluminium, though glass, ceramic or other metals may be used, and supported by spring clamps at their mid-points so that they may be excited into longitudinal vibration at their resonant frequencies on being struck by a hammer 220. The arrangement shown comprises four rods which resonate at 38, 39, 40 and 41 kc/s. On depressing a push-button 206, a rod 207 carrying a cam lever 211 is likewise depressed and a projection 216 from the lever 211 engages in a recess in a rod 218 carrying the hammer 220 so that the rod 218 is simultaneously pulled down. Eventually, however, the lever 211 engages a stop 223 which causes it to rotate against the action of a spring 213, thereby releasing the rod 218. This moves upwards under the action of spring 219 causing hammer 220 to strike the rod 201 which then generates an oscillation at its resonant frequency. When the push-button 206 is released, a damping element 225 contacts the rod 201 to damp its vibrations. The generated oscillations may be used for the remote control of a television receiver as described in Specification 867,764.

Title: Optical-mechanical scan rate multiplier
Inventor: CLYNICK ANTONY JOHN
IPC: G02B26/12
Filed: 1987-07-22
Abstract: A combined optical and electronic system to increase the scan rate of a scanned light beam on an imaging plane or screen by optically multiplying the scanning effect of the rocking scanning device or rotating polygon P, without increasing the rocking or rotational speed. Each low speed scan of the light beam carries, sequentially, intensity modulation information of several lines of a video, computer or other scanned image signal. A number of mirrors M1-M4 corresponding to the number of modulating signal lines reflect the scanned light beam in such a way that the single long duration scan of the rocking scanning device or polygon is converted into several short duration scans, corresponding to the modulating signal lines, and combined at the image plane or screen S. The speed and phase of the scanning device or polygon is controlled by an electronic dividing and timing circuit to ensure each part of the scanned light beam is reflected by its corresponding mirror. The system has direct applications to increasing the scan rate of video projectors, laser printers, bar-code readers, facsimile machines and other similar devices which employ scanned light beams. <IMAGE>

Title: Working a facet of a gemstone
Inventor: HANNA MARK CHRISTOPHER
IPC: B24B9/16
Filed: 1988-11-17
Abstract: In order to determine in which direction a facet of a gem stone should be polished, a polishing head 3 and a dop 5 are mounted on a tang 2 for free rotation about a vertical axis 9, the gem stone 6 being a substantial distance d from the axis 9. There is a small electric motor 12 connected to the polishing head 3 by way of a large reduction gearbox 11 and a small shaft 10, so that the polishing head 3 can be slowly rotated about the axis 9. In order to determine in which direction the facet should be polished, the polishing head 3 is rotated a few times at slow speed, and the scratch marks on the stone 6 are observed to determine the angular relationship at which polishing best occurs. In order to work the facet, particularly where there is more than one crystallographic orientation, or where one wants to omit the grain seeking step, the polishing head 3 is rotated continuously until the facet has been formed. In order to smooth the facet, the rotation is continued until the facet has a highly polished surface. <IMAGE>
