Abstract: 762,745. Superheterodyne circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 6, 1954 [Dec. 9, 1953], No. 35254/54. Classes 40(5) and 40(6) A self-oscillating frequency-changer comprises a valve with a tuned Lecher line ¢L3, ¢L3, as oscillator circuit. One side of the line is connected to the grid and the other to cathode via inductance L8 and condenser C2 which serve for balancing the line at the two ends of the tuning range. Oscillations are maintained by a backcoupling loop L4 in the anode circuit, in series with a blocking condenser which tunes the primary of the first I.F. transformer L6. Signals are introduced into a further Lecher line L2 which is coupled to the neutral point on the oscillator line ¢L3, ¢L3 by means of the joint tuning bridge B, via a coupling loop L1. A series inductance L9 provides for tracking. Regenerative feedback is provided at signal frequency by inductance L5, in conjunction with the valve capacitors, and at intermediate frequencies by condensers C1, 5 in conjunction with resistor R2. In a modification (Fig. 3, not shown) the inductances L8, 9 are dispensed with, the necessary differences in inductance of the lines being obtained by using curved lines of differing radii.

Abstract: 1,190,655. Tamping railway ballast. F. PASSER. 4 Aug., 1967 [5 Aug., 1966], No. 35963/67. Heading B1G.

Title: Electric frequency modulation signal demodulation apparatus
IPC: H05B41/06
Filed: 1973-07-27
Abstract: 1436212 Interference suppression; frequency discriminators; muting MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 27 July 1973 [28 July 1972 (2)] 35998/73 Headings H4L H3A and H3Q A demodulated f.m. signal is blocked by a gate 13 in the presence of interference, or the absence of carrier signal (muting), the gate 13 being controlled by monostables 16, 17. A received f.m. signal is amplified and limited at 11 to give a rectangular wave whose positive and negative edges trigger by way of a differentiator 15 the respective monostables 16, 17. Their output pulse durations are fixed and are slightly less than the period of the received carrier at its highest frequency. At least one monostable must therefore be producing an output at any time while a carrier is being properly received, and an adder 18 senses this (the result of the addition is signal E, Fig. 2 not shown) to hold gate 13 conductive. An excessive delay between successive edges of a received signal (A, t 1  in Fig. 2, not shown) due to interference or carrier loss, causes both monostable outputs to disappear together (t 1 - t 2 ) and this blocks gate 13. The period of blocking may be extended (to t 3 ) to allow for transients. A delay circuit may be included at the signal input to gate 13 to allow for operating delay in the gate. F.M. Discriminating.-The demodulated signal fed to gate 13 is either obtained from an undisclosed discriminator fed from limiter 11 (12, Fig. 1, not shown) or is obtained, Fig. 3, by filtering at 20 the added monostable outputs.

Title: Bilateral parametric amplifier
IPC: H03F7/04
Filed: 1960-10-20
Abstract: 971,455. Parametric amplifiers. STANDARD KOLLSMAN INDUSTRIES Inc. Oct. 20, 1960 [Oct. 23, 1959], No. 36034/60. Heading H3B. A parametric amplifier arranged for bothway operation comprises two semi-conductor diodes 14, 30 acting as capacitative reactances with individual tuned signal circuits 16, 20 and 33, 32, a common pump source 26 and a common idler circuit 23 tuned to the sum (fp +fs) of the pump and signal frequencies. Capacitors 21, 34 are of high capacity and in effect ground the terminals of inductors 16, 33 for high frequencies. A signal on lead 22 is mixed with the pump frequency in diode 14 and the sum frequency ## +#s excites the circuit 23. From the sum frequency #p +#s and the pump frequency fp, the diode 30 derives the signal frequency fs which is available in amplified form on lead 38. The upconversion gain in diode 14 and the downconversion loss in diode 30 balance out. The resultant gain is attributed to the existence of (fp-fs) in the output of diode 14. In each diode # = (#p - #s) + #s the condition necessary for amplification. A signal input on lead 38 gives an amplified output on lead 22. The frequency bands used for the two directions do not overlap but both bands fall within the transmission band of the amplifier. The two diodes are biased by batteries 19, 37.

Abstract: 872,049. Hinges and pivots. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 25, 1957 [Nov. 26, 1956], No. 36078/56. Class 65(2). A flexible strip type hinge comprises two members 1, 2 (Fig. 1) disposed about a pivotal axis A-A and at least two flexible elements 5 tying them together and arranged so that in one relative position of the members about the axis the elements lie in the same plane and in the event of tensile or compressive stress being applied across the hinge in this plane transversely to the axis one or more of the elements would be placed in tension and thereby prevent buckling of the other element or elements. The elements are fastened to the members by bolts 6 passing through clamping plates 7. Two pairs of these hinges may be used in a parallel-motion linkage, two rigid parallel straps being hinged at their ends to the two relatively movable parts. The elements may be made of spring steel, natural or synthetic thread having good tensile properties, or fabric formed of such thread. In Fig. 5 two members 11, 12, each of which may be built up from a number of separate wedge portions bolted together, are hinged by flexible strips 17 having clamping plates 18. The plates 18 may be formed in pairs as shown in Fig. 5a. A flexible cord (not shown) may be stretched along the axis B-B and attached to the members 11, 12 to resist any tendency towards relative axial movement therebetween whilst not obstructing the free action of the hinge.
