Title: Receiver circuit for frequency modulated signals
IPC: H04B1/26
Filed: 1953-05-29
Abstract: 726,612. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. May 29, 1953 [June 4, 1952], No. 15048/53. Class 40 (5). A frequency-modulated received wave is converted into a succession of square wave pulses of even amplitude by a plurality of cascaded limiters, the output of which is fed to a counter type detector. The receiver is particularly applicable to a frequency division multiplex sub-carrier system, in which a broad band of signals modulates the frequency of a subcarrier wave which itself modulates a radiated wave of higher frequency. The received F.M. sub-carrier 47, Fig. 3, is applied to a cascade of limiter stages 14, 42 ... 46 from which it emerges as a square wave 48 which is fed through a cathode follower 49 to a counter discriminator 9. Each limiter stage comprises a double triode tube 16, 18 coupled by a common cathode resistor 17. The input wave 47 is applied to the grid of the section 16, and the grid of the section 18 is earthed for the wave frequency by a capacity 36 and both grids are given a set positive bias by a potential divider 22, 23 across the B+ source. Output is taken from the anode of section 18 across a resistor 19 and is fed through a suitable time constant circuit 39, 41 to the input grid of the next stage 42 which operates similarly to the first stage 14. The output of the final limiter 46 is fed through a condenser 54 to the grids of a pair of parallelled triodes 49 operating as a cathode follower, the cathode resistor 52, 53 being in shunt to a condenser 57 and resistor 60. Sharp pulses 61 are thus produced across the resistor 60 at each rise of the square pulse 48; and the desired signal is produced by feeding the pulses 61 through a low-pass filter to a broad band amplifier. Crystal diodes 58, 59 direct the passage of the charging and discharging currents of the condenser 57. A resistor 56 of low value, connected between the grids of the parallel triodes 49, suppresses parasitic oscillations. The curves of Figs. 5, 5a and 5b show the output voltage of the successive limiters for input signal voltages at the respective levels of 1000, 100, and 10 millivolts. The Specification also includes a diagram (Fig. 4, not shown), of the characteristic curves of the limiter stages showing the anode current of the output section plotted against the grid voltage of the input section, for various' values of the bias on the grids.

Abstract: 101,978. Aarts, C. J. G. Oct. 26, 1915, [Convention date]. Ammonium sulphate.-Zinc sulphide, is converted completely into sulphate by heating with oxygen or gases containing oxygen under pressure. The Specification as open to inspection under Sect. 91 (3) (a) states that the zinc sulphide treated may be zinc blende, waste products containing zinc sulphide or precipitated zinc sulphide, and describes the invention in connection with a process of purifying gas by washing with a solution of zinc sulphate so as to produce zinc sulphide and ammonium sulphate, in which the zinc sulphide is required to be converted into zinc sulphate for use again. If the gas to be purified contains too little sulphuretted hydrogen, more is added by mixing calcium sulphate with the carbonaceous charge of the retort. Calcium sulphide is first formed and is decomposed by water which is injected into the lower part of the retort. This subject-matter does not appear in the Specification as accepted.

Abstract: 361,334. Hydraulic transmission of power. RAMPLING, R., Dunedin, Stanley Road, Hoylake, and WATKINSON, A. S., Silverdale, The Mount, Heswall, both in Cheshire. May 19, 1930, Nos. 15313, 16389, and 29965. [Classes 69 (ii) and 135.] The rotating casing of a hydraulic clutch is provided with a series of emptying valves adapted to be operated by pressure transmitted from the interior of the clutch rotor, from a fixed enclosing casing, or from an independent source, dashpot arrangements being provided, if desired, to secure slow closing, and the valves being so arranged that centrifugal force has no effect on them or is balanced. The rotating casing is also provided with air-escape valves which are open while the clutch is being filled, and are closed when the pressure in the clutch reaches a predetermined value. A clutch installation shown in Fig. 1 in the normal running position, comprises a rotating clutch casing A having emptying valves H, a fixed casing C, and a pump p for maintaining a circulation of liquid through the clutch and a cooler p4. The pressure in the casing A may be varied by varying the pump circulation, or by moving a lever G into the position shown in Fig. 2. The movement of the lever closes the vent N of the casing A by a valve n<1>, opens a valve k<1> to admit compressed air at k<2>, and moves a valve F to byepass the pump. The admission of compressed air to the clutch through a pipe p<2>, chamber c<3>, and ports a<5> raises the pressure in the clutch, and the valves H are thereby opened. The lever G may then be moved into mid-position to vent the casing through p<2> and N, and to close the compressed air valve k<1>. The valves H may be pressed outwardly by a spring 5, Fig. 4, and are opened by pressure passing through a passage 10 to the upper side of a piston 6. A scoop-like passage 8 leading to the interior of the valve and vents 13 are provided. In another form so disposed that centrifugal force has no effect, the valve 72, Fig. 7, is connected to a dashpot piston 74. Other forms are also described. One form of air-escape valve comprises a piston 17, Fig. 8, adapted to close the valve 15 against the action of a spring 19 ; an air-escape valve may also be combined with an emptying valve. An installation controlled by the pressure in the fixed casing C comprises a lever J<1>, Fig. 10, controlling the position of a compressed air valve k<10> and a casing valve s, the emptying valves H<13> being opened by pressure from the casing C admitted through passages 98, Fig. 13, and acting on a piston 92. In the form shown in Fig. 17, an independent source of pressure is connected under the control of a valve k<1> through passages t2, a<6> to the actuating cylinders of the valves H<16>.

Filed: 1975-04-15
Abstract: 1494582 Distance measurement SIEMENS AG 15 April 1975 [21 Feb 1975] 15328/75 Heading H4D An aircraft provided with a V.O.R. receiver, preferably of the kind described in Specification 1,494,235, determines its distance from a V.O.R. beacon S, Fig. 1, by making a flight path detour to fly at right angles to the line of direction to the beacon and determine by oscillator counter means the time (t 2 -t 1 ) between the bearing indication making n incremental changes. If the incremental change α is small then The oscillations at frequency f are counted for (t 2 -t 1 ) minutes and for this to represent the time that the aircraft would take at the same speed v to reach the beacon or Thus for n= 1 and α = 1‹ f= À9549 H 3 . In the V.O.R. receiver of Fig. 3 the 30 H 3  a.m. bearing signal is selected by L.P.F. 2, converted to a square wave by limiter 3 and to a series of short pulses by differentiator 4. The reference 30 H 3  signal f.m'd on a 9960 H 3  carrier is selected by H.P.F. 8 and detected by F.M. demod. 9. A frequency multiplier 10 provides a pulse for every increment of bearing, e.g. if α = 1‹, it has a factor of X360‹ and gives a frequency 10,800 H 3 . These pulses are counted at 11, 0 to 359 and reset to 0, via divider 12. The required α = 1‹ unit pulses are tapped from the counter at E1. The counter content when a bearing signal pulse from differentiator 4 reaches a store 7 registering the counter content, is transferred to a decoder 13 for a bearing readout at 14. A double D flip-flop 20, Fig. 4 fed with the 1‹ signals from terminal El and the bearing signal pulses from terminal E2 only responds to changes in the bearing after the initiation of the measuring operation. The measuring operation is signalled by a 50 m.sec. pulse from trigger circuit 23 upon pilot actuation of switch 24. The outputs of the flip-flops are combined in an exclusive OR logic circuit 25, 26, 27 such that a luminescent diode at the circuit output lights when the first 1‹ signal indicating a bearing change occurs (i.e. at t 1 ) and goes out when the next such 1‹ signal occurs (i.e. at t 2 ). A (t 2  - t 1 ) indicative pulse occurs at A 1 for gating through the À9549 H 3  pulses to a counter and display. Commercially available I.C. units may make up the B.C.D. counters and displays (Fig. 5, not shown).

Abstract: 351,676. Conveying furnace charges. COCHRAN, R. S., 2375, Dorr Street, Toledo, Ohio, U.S.A. May 19, 1930, No. 15381. Convention date, May 18, 1929. [Classes 51 (i) and 51 (ii).] In a step-by-step conveyer for furnaces of the kind comprising fixed and movable frames B, C formed of parallel longitudinal rails having undulating upper edges, the rails of the fixed frame B are rigidly secured to a bar 18 at the discharge end of the furnace and are maintained under tension by springs 23 which are arranged on rods 25 rigidly mounted on a rail-supporting bar 19 and bear against abutments 24 on the rails. The expansion and contraction of the rails B are utilized to regulate the temperature of the furnace, the longitudinal movement of the rails being transmitted through a cable 27 to the operating arm 28 of a valve 29 controlling the supply of gas through pipe 30 to the burners 17. A spring tends to keep the valve 29 open and the cable 27 taut, and an adjusting screw 31 actuated by a hand-wheel 33 is provided for regulating the valve setting. The rails of the moving frame C are formed in sections extending between saddles 80 mounted on cross-bars 40, warping of the frame, due to unequal expansion, being prevented by rigidly securing the outer rail sections only to the saddles, the sections of the intermediate rails being slidably connected at one end to the saddles by a pin engaging in an elongated slot. The cross-bars 40 are suspended by means of side members 41 and rocker arms 44 from overhead shafts 45 on which are fixed levers 48 pivoted to a common actuating bar 49. The latter is reciprocated, to raise and lower the frame C, through rod 52 and bell crank 53 by a rocker 51 engaging a cam 50, horizontal movement being imparted to the frame by a cam 55, rocker 56, and link 57. The limits of the horizontal movement of the frame are so chosen that the suspension members 41 are always inclined to one side of the vertical, this arrangement serving to maintain the rails under tension and to prevent backlash in the mechanism. The part of the frame C projecting beyond the furnace charging opening 14 is rigidly connected to a platform 60 which is formed with ramps 66 resting on rollers 63, the latter being mounted on rockers 64 connected for simultaneous operation by a link 65.
