Title: Improvements in or relating to transmitters for carrier-frequency-shift telegraphy systems
Inventor: FOOT JOHN BARTRAM LOVELL
IPC: H04L27/12
Filed: 1960-05-06
Abstract: 903,315. Frequency changing. GENERAL ELECTRIC CO. Ltd. May 4, 1961 [May 6, 1960; April 21, 1961], Nos. 16117/60 and 14433/61. Class 38 (2). [Also in Group XL (c)] In a frequency shift carrier telegraphy system carrier is applied to a resonant circuit 4, 12 with rectifier bridge giving a phase reversible output so that outputs in phase or phase opposition in accordance with Œ D.C. telegraph signals applied at 16 are applied to R-C networks 22, 23 and 19, 28 giving Œ45 degrees phase shift respectively and a rotating electromagnetic field is produced by a pair of crossed coils 30, 31 in the cathode circuits of valves 25, 27. This reverses in direction with the telegraph signals so that from a pick-up coil 35 rotated at constant frequency by a synchronous motor 37 in the field, equal to or a harmonic of the repetition rate of the keying signal, either a sum or difference frequency is produced as output from the transformer coils 36, 38, and used for telegraph signalling. The coils 30, 31 may be wound in two halves on opposite pairs of segments of a ferrite ring 29 (Fig. 2) arranged at right angles. In Fig. 3 (not shown) the oscillator 1 directly feeds C-R and L-R networks producing Œ45 degrees phase shift connected to the two input terminals of the rectifier bridge with output connected to two series connected resonant circuits tuned to the oscillator frequency. Telegraph ŒD.C. signals applied to the junction of the tuned circuits therefore changes by Œ 90 degrees respectively the phase of the quadrature phase oscillations in the tuned circuits and these, arranged at right angles, reverse the direction of the rotating field they produce through a rotating pick-up coil. The quadrature coils may be replaced by arcuate capacitor electrodes, producing a rotating electric field, as in Specification 637,996.

Abstract: 529,532. Combination locks. PICON, A. June 2, 1939, No. 16267. Convention date, June 3, 1938. [Class 44] The bolt of a lock, not shown, is blocked by a plate 1 mounted on slidable spindles 3, 4, 5 so that it can be moved bodily into or out of engagement with a notch in the bolt. The spindles are rotatably anchored to plate 1 by discs 9, 10, 11, and are locked against endlong movement by projections 20 co-operating with locking discs. As shown there are two sets of locking discs, 14, 15, 16 and 17, 18, 19 with key-hole apertures 30, and notched peripheries. Normally, discs 17, 18, 19 are held against rotation by set-screws, not shown, co-operating with the notches, which allow the angular setting of each disc to be altered to change the releasing combination when desired. Discs 14, 15, 16 are rotatable by means of projections 26 engageable by one or other of the side faces of the projections 20. Endlong movement of a spindle is possible only when the apertures in the corresponding fixed and rotatable discs are aligned to allow passage of the projections 20. The discs are housed in a fixed casing comprising plates 24, 25 with apertures to receive the discs, an intermediate plate 22, and cover plates 21, 23. The edge of each disc 14-16 is engaged by a sliding detent 12 under action of a blade-spring 13. The spindles are operable by knobs 6, 7, 8. Fig. 1 shows plate 1 in inoperative position. When the discs are correctly set a compression spring 28 moves plate 1, together with the spindles, to the bolt-engaging position. To set the discs each spindle is moved a complete rotation to engage one face of a projection 20 with projection 26, and the rotation is continued to the requisite setting, which is facilitated by markings on a face-plate 29. The spindle is then reversely rotated 180 degrees to register the projection with aperture 30.
