Filed: 1945-11-06
Abstract: 637,292. Valve generating circuits. SOC. ANON DE TELECOMMUNICATIONS. Nov. 6, 1945, No. 29588. Convention date, Dec. 16, 1942. [Class 40 (vi)] A thermionic valve oscillator comprises amplitude limiting means connected in parallel with the tuned circuit which is associated with the valve, and a circuit including an element whose impedance increases with frequency is connected between a point on the inductance of the tuned circuit and an input electrode of the valve to provide negative feed-back. Fig. 2 shows a circuit in which, it is stated, oscillations are produced and negative feed-back is provided by means of inductance 7 and resistance 8 which are connected between the inductance of the oscillating circuit 3, 3<1>, 4 and the valve cathode via the earth contact. The metal rectifying elements 6, 6<1> limit the amplitude of the oscillations in the oscillating circuit and the tendency for harmonics to be produced by these elements is countered by the effect of the negative feed-back circuit due to the increase of impedance of this circuit with frequency. A saturated core inductance may be used in the negative feed-back circuit to produce the same effect. A similar circuit is described in which an additional valve is employed, the connections between the grid and cathode of the first valve and the tuned circuit being reversed to compensate for the phase reversal introduced by the second valve. The Specification as open to inspection under Sect. 91 also describes the use of a tungsten filament lamp for amplitude limiting purposes, and several alternative positions of the amplitude limiting element are shown. This subject-matter does not appear in the Specification as accepted.

Patent GB-854865-A (GB)
Title: Improvements in or relating to alternating current track circuit railway signalling arrangements
IPC: B61L23/16
Filed: 1957-09-23
Abstract: 854,865. Railway signalling systems. WESTINGHOUSE AIR BRAKE CO. Sept. 23, 1957 [Sept. 21, 1956], No. 29810/57. Class 105. A railway signalling system includes interrupted alternating-current track circuits in which adjacent sections are supplied with currents in phase opposition. The track relay such as relay BTR of section B is normally operated at the interruption rate whereby a two-relay arrangement BFSA, BBSA maintains the contacts thereof on their front contacts so that the wayside entry signal BS for section B displays the proceed aspect G. Entry of a train or leakage of antiphase current from an adjacent section A has as a result that the track relay BTR will not oscillate its contact 4 and so relay BBSA will drop its contact to change the wayside signal BS to the stop aspect R. The track relay BTR is shown as a two-winding direct-current polar relay with one winding b energized through rectifier K2 from the track circuit through a secondary winding 14 of a transformer 10 connected across the rails at the entrance end of section B. The other winding a is energized through rectifier K1 from the series connected secondary winding 13 of the transformer 10 and secondary winding 17 of a transformer 11 giving voltage of opposite phase by the primary winding 15 of this transformer 11 being connected to the common supply 58 for the track sections. Thus in the event of leakage from section A the voltage of secondary winding 13 will be reversed and so become additive to the voltage of secondary 17 and winding a will become permanently predominantly energized over winding b and so set the wayside signal to the stop aspect R. In ordinary operation however, during the " on " periods of the trackcircuit current in section B the winding b is predominant and sets its armature 4 on the normal contact 5 while during the " off " periods, since the secondary windings 13, 14 of transformer 10 are then without voltage and only the secondary winding 17 of transformer 11 is effective, the winding a alone is energized and sets its armature 4 on the reverse contact 6. Thus the armature 4 will oscillate and the two-relay arrangement BFSA, BBSA will be effective to set up the clear aspcet G for the wayside signal BS. When a train enters section B the transformer 10 is shunted out so that only the winding a of the track relay BTR is energized, by current from the secondary winding 17, and accordingly the armature 4 remains on its reverse contact 6 so de-energizing relay BBSA which drops its contact to give the stop aspect R on the wayside signal BS. Modifications are described in which capacitors are inserted to provide filter circuits for attenuating stray commercial currents, Fig. 3 (not shown), in which the secondary winding 14 has in series an additive secondary winding of the transformer 11, Fig. 4 (not shown), and in which a single-winding polar relay is used by being inserted across a series circuit of the two rectifiers K1, K2, Fig. 6 (not shown). Specification 611,629 is referred to.

Abstract: 534,760. Valve amplifying circuits. ERICSSON TELEPHONES, Ltd., and HOPWOOD, F. W. Nov. 13, 1939, No. 29932. [Class 40 (v)] A complex wave form which is resolvable into a plurality of component wave forms having amplitudes approximately inversely proportional to their frequencies is applied by means of a transformer T<SP>2</SP> to the grid of a valve V whose load impedance comprises a plurality of circuits C 1 L 1 , C 2 L 2 , C 3 L 3 , each tuned to the frequency of a wanted component and each having the same effective resistance and inductance. With this arangement, the gain of the valve is proportional to frequency and so the output voltages of the component frequencies are the same.

Title: Combined inflating coupling and fluid pressure gauge

Abstract: 339,708. Schrader's Son, Inc., A., (Assignees of Wahl, J., and Melzer, 0.). Oct. 17, 1928, [Convention date]. Pneumatic-tyre pressure gauges.-A combined inflating coupling and gauge comprises a coupling member, a gauge device, and means for connecting the coupling device with a source of air supply and with a tyre valve, the coupling in one position relative to the gauge device, establishing communication between the source of fluid pressure and the tyre, and in another position, establishing connection with the gauge device, without in either position establishing connection between the supply and the gauge. The body portion A has a base B in which fits the inflating tube C the projecting end of which is formed as a pressure foot D fitted with a valve E. In the form shown, the tube 0 is permitted a. limited angular movement relative to the body portion determined by a set screw F and arcuate slot G. A torsion spring H holds the parts in the position of Fig. 1. The inner end of the tube C is formed as a tapered valve plug J engaging a corresponding valve seal in the vase. A spring o the tension of which is adjustable by a nut N keeps the plug against its seating. The main inlet of air is through the nipple P which screws into the body portion. The air passes through a short passage Q and port R to the tube and hence tothe tyre, the valve E being held up by the tyrevalve nipple. In the position shown in Fig. 3, the port S in the plug registers with a passage T which passes round a loose sleeve and the air encircles the gauge cylinder V until a passage W is reached communicating with the chamber X of the gauge. The latter comprises a piston B<1> and loading spring C<1> bearing between the piston and a washer D<1>. The indicating member is a graduated flat bar E' which projects through the top of the gauge. At the lower end the bar E<1> is formed with an enlargement E<2> which abuts against the piston and serves also to guide the bar and prevent its being caught in the convolutions of the spring. Flanges V<1> protect the gauge bar from damage. The washer D<1> is provided with a friction spring U<1> which causes the bar E<1> to remain in the position reached. The gauge is fitted with a permeable washer Q<1> clamped between two washers with central apertures to prevent the air entering the gauge too rapidly. When in the position shown in Fig. 1, the gauge is vented to the atmosphere.
