Title: An electric circuit for detecting an audio frequency signal
IPC: H04W88/02
Filed: 1970-03-03
Abstract: 1,246,782. Electric selective signalling. STORNO A.S. 3 March, 1970 [11 March, 1969], No. 10095/70. Heading G4H. An electric circuit for detecting an audio frequency signal comprises a switching circuit 3 which tunes a band-pass filter 2 in successive intervals of time to each of the frequencies f 1 , f 2  of the signal fed to an input terminal X, a rectifier circuit 5, an integrating circuit 7 having a discharging time constant less than its charging time constant, a Schmitt trigger 8 and an indicating device 9. The rectified voltages due to the signals of each frequency f 1 , f 2  are added by the integrator for a time which is less than or equal to the charging time constant of the integrating circuit and if both frequencies are present, the total voltage exceeds the threshold voltage V T  of the Schmitt trigger 8 thus causing the device 9 to give an indication. If, however, one frequency is absent the integrator discharges during the period for which the filter is tuned to the absent frequency and the output of the integrator does not exceed the threshold voltage of the circuit 8 so that the indicator is not energized. A second Schmitt trigger 6 ensures that the circuit is not actuated by noise voltages less than the threshold voltage V O  of this circuit. The switching circuit 3 may comprise relays and change-over switches or an astable multivibrator and the invention may be applied to the detection of the absence of one or more frequencies from a signal consisting of more than two frequencies.

Abstract: 894,232. Electromagnetically-actuated valves. MAROTTA VALVE CORPORATION. March 23, 1960, No. 10366/60. Class 135. An electromagnetically - actuated valve comprises a movable valve member 25, Fig. 1, formed with two sealing faces 22, 32 which co-operate with two longitudinally - spaced seats. The valve member 25 is actuated in one direction by an electromagnetic motor 80 comprising a winding 84, a core 85 and an armature 86 which is secured to a stem 88, the stem contacting the valve member and moving this member to the right against a spring 62, which spring moves the valve to the left when the motor is de-energized. The valve seats comprise a ring 20, Fig. 3, of plastic material and strenthening-rings 26, 27 of metal, preferably aluminium. A sleeve 33, Fig. 1, is provided between the seats and a sleeve 36 and nut 42 fix the seats in position. The motor 80 is such that the force attracting the armature increases as the armature moves towards the coil at a rate which is greater than the increase in the opposing force of the spring 62, thereby the face 32 impacts against the seat and deforms it. Similarly, on de-energizing the motor, the spring 62 causes the same action on the other seat. Connections 69, 76, 72 communicate with the valve bore on either side and between the seats respectively. The valve is balanced by piston members 48, 58 and a third piston member 49 and a vent 52 prevent leakage to the motor. The spring 62 may be adjusted by a nut 64 and the armature may be adjusted relatively to the stem 88.

Abstract: <PICT:0386300/III/1> In the destructive hydrogenation of liquid carbonaceous materials such as coal tar, petroleum, coal pastes and the like, the catalytic surfaces are in the vertical plane and are closely spaced.  The surfaces may be flat or corrugated, or may consist of rolls of metal gauze, or bundles of tubes, and may themselves be of catalytic metal, or may be coated with a catalyst; suitable catalysts are silver, copper, cadmium, lead, bismuth, zinc, chromium, iron and oxides of molybdenum or tungsten, and of magnesium or aluminium.  Oil from a pipe 4 is mixed with hydrogen from a pipe 5 and passed through a heat exchanger 7 to a heating coil 9, where it may mix with a coal and oil paste from pipe 18, and is then passed into a catalytic chamber 3.  The coal paste may also pass directly into the chamber by a pipe 17.  The mixture passes out of the chamber through the heat exchanger 7 to a separating vessel 20; vaporous products are condensed in a coil 22, while excess hydrogen passes through a separator 24 and purifier 25 back to the pipe 5.  The heavier liquid products either pass directly back to the reaction chamber by pipe 29, or are freed from solids in filters 32, 33; the filtrate from the latter may be mixed with powdered coal from a disintegrator 13 and passed back to the reaction chamber by pipe 17, or may be partially fractionated in a still 38 and the heavier fraction passed back to the coil 9 by pipes 48, 4.  The coal may be suspended in the colloidal state in an oil, which is preferably a product of the reaction.
