Abstract: 883,398. Signal filtering systems. LABORATORY FOR ELECTRONICS Inc. March 24, 1958, No. 9367/58. Class 40 (4). [Also in Group XL (c) ] A signal filter comprises a means for shifting the input signal from a first portion of the frequency spectrum to a second portion of the spectrum, which includes zero frequency; means for selectively filtering the shifted signals to remove any zero frequency component ; and means for restoring the shifted signals to the first portion of the frequency spectrum. The input signal containing a component at a frequency # 0  is fed into two modulators 13, 14 (Fig. 1), into which are also fed quadrature signals from a reference source 15 having a frequency # 0 . The outputs from the modulators are fed into filters 21, 22 which remove the zero frequency component and are subsequently fed via amplifiers 23, 24 into a single side-band modulator 25 which receives as its other input the two quadrature signals from the reference source # 0 . The output from the modulator is fed into a filter amplifier 26 giving an output at the same frequency as the initial input but with the component at a frequency # 0  removed. In a practical embodiment (Fig. 2), the inputs are fed into diode bridge modulators 33, 34 and the output from the reference source 15 is divided into two quadrature outputs by means of the RC networks 35, 36, 37, 38. The outputs from the modulators are fed into low-pass filters 21, 22 and the D.C. component of the output signal is removed by capacitors 43, 44. The output from the filters is fed through amplifiers, each of which includes a pair of cathode coupled triodes 51, 52 driving a unity gain low-drift zero D.C. level stage consisting of cathode coupled triodes 53, 54 and a triode cathode follower 55. The single side-band modulator 25 is formed by a pair of balanced modulators including diode bridges 61, 62, the quadrature drive from the reference source being obtained by further RC networks, a resistor 63 being included to reduce the level of the reference signal # 0  applied to the modulator. The output from the balance modulator is applied to the control grid of the pentode amplifier 67 which is tuned to reject the high order modulation products. The overall frequency characteristic is shown in Fig. 4 to have a narrow band stop at a frequency # 0 . A band-pass characteristic could be provided by reversing the positions of the capacitors 43, 44 and resistors 45, 46. Specification 644,136 is referred to.

Abstract: 769,617. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. April 1, 1955, No. 9537/55. Class 40 (1). In equipment for indicating whether, in a multi-stage electronic register, the number of stages in one of two alternative states differs from a given number, the stages are connected to a set of gates connected in groups to gates of a second set, such that one and only one gate of the second set is operable when the given number of stages of the register is in the one state, and a detector is operable when the number of operated gates of the second set differs from one. As shown, a register PR has 5 stages comprising e.g. electronic valves 2 of which should be fired. Adjacent stages are connected in pairs to coincidence gates GA1- GA5, and non-adjacent stages to a similar group of gates GA6-GA10. The outputs of the groups are connected via further gates GB1, GB2 to bistable trigger devices BS1, BS2. If more than 2 valves are fired, both gates GB1, GB2 will be operative and both devices BS1, BS2 will be set to the " 1 " state ; and if less than 2 valves are fired, the trigger devices will both remain in the " 0 " state. A " check " pulse will then be allowed through gate GD or GC and will set an " alarm " trigger device AL via gate GE. Similar circuits for other registers may be connected to points P1, P2. A generalized circuit (Fig. 1, not shown), is described in which the check pulse is applied to GE. In an alternative form, the gates GA are threshold-1 gates and gates GB coincidence gates. The gate connections for both forms are given for the 2-out-of-5 arrangement shown, for 2 out of 6 and for 3 out of 7.

Abstract: 576,893. Lighting burners. MAY, P. (Robertshaw Thermostat Co.). May 23, 1944, No. 9928. [Classes 75 (i) and 75 (ii)] [Also in Group XXIX] The manual or thermostatic opening of a valve 14 in the supply pipe 12 of a gas burner 10 closes the secondary circuit of a transformer 20 to supply current to the actuating coil 68 of two initially closed delayed action switches 26, 62 and causes the energization of an ignition coil 28 for the burner 10. After a short delay of say 5 seconds allowing the coil 28 to reach ignition temperature the switch 62 opens and removes a shunt to the solenoid of a valve 16 in the pipe 12 to permit gas to pass to the burner 10. After a further period of say 13 seconds the switch 26 opens and breaks the circuit to the coil 28. The current passing through the solenoid is then insufficient to hold the valve 16 open unless ignition has occurred and the flame has heated a ballast resistor 74 which with an adjusting resistance 76 forms a shunt to the solenoid. The switches 26, 62 are preferably of the mercury type having a delayed opening with an instantaneous closing action such as described in U.S.A. Specifications 1,778,439 and 2,224,873. The resistor 74 has a relatively low normal resistance and a positive coefficient of resistance. The ignition coil 28, switch 26 and a resistance 30 form with .a control resistance element 32 a parallel mesh arranged in series with solenoid of valve 16 and its shunting circuit containing the switch 62. A cut out 60 operated if the circuit through the resistor 74 is broken may be provided in solenoid circuit. A manually operated switch 86 and a resistance 94 may be provided in parallel with the coil 28 to enable the burner to be ignited by a match if the coil 28 breaks.
