Abstract: 1,101,793. Measuring force electrically; dynamometers. NAUCHNO - ISSLEDOVATELSKY INSTITUT TEPLOENERGETICHES KOGO PRIBORO STROENIA. April 26, 1965, No.17530/65. Headings G1N and G1W. A force is measured by using it to control the frequency of transverse oscillation of a tensioned elongate member, which frequency is detected electrically. The tensioning means includes a spring of adjustable stiffness.  The unknown force is applied to the free end of a lever 2 whose other end is connected to the oscillating member, wire 3. The lever pivots about an axis defined by the crossing point of support springs 14 and is secured on the pivot axis to one end of a resilient rod 4 which functions as a torsion spring when the lever is deflected. The other end of this rod is restrained from rotating by a clamp 5 which can be moved axially of support cylinder 6 to vary the effective length and hence the stiffness of rod 4. Such adjustment varies the relationship between force input and frequency output. To set the zero-force frequency the rod may be twisted before securing it and fine adjustment may be obtained by varying the tension of an auxiliary spring 17. The wire 3 vibrates in the field of a permanent magnet 7 and the induced A. C. current is fed to an amplifier 8 and thence back to the wire to sustain the oscillations. A meter (not shown) indicates the frequency of these oscillations. The wire may constitute one arm of a bridge circuit whose output is fed to the amplifier.

Title: Facsimile transmission of pictures
IPC: H04N1/41
Filed: 1978-05-05
Abstract: In transmission of facsimile signals, a known technique is that an image signal having a polarity with a minimum amplitude for one information state (white or black) and another amplitude for another information state (black or white), is converted before transmission into a 3-level signal, that is a signal of changing polarity. This saves transmission bandwidth. The method of conversion is that each change of the image signal causes a reversing pulse, and reversing pulses successively cause a change to one polarity, to the null state, to the other polarity, to the null state, etc. However, with this method, short black or white marks, which give an image signal of insufficient amplitude for reversing (Fig. 6a), are lost (Fig. 6b). To avoid this, before it is used to form the reversing pulses, the image signal is subjected in this method to amplitude splitting (Fig. 7a) and then compared with a threshold value to obtain the reversing pulses. In this way, image signals with an amplitude which would otherwise be insufficient are not lost (Fig. 7b). <IMAGE>
