Title: Improvements in or relating to electrical frequency control systems suitable for use in radio and like transmitters
IPC: H03L7/06
Filed: 1933-09-20
Abstract: 425,692. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London. - (Assignees of Usselman, G. L. ; Port Jefferson, Long Island, New York, U.S.A.) Sept. 20, 1933, No. 26005. Convention date, Oct. 18, 1932. [Class 40 (v)] The frequency of a high-power transmitter A, Fig. 1, is controlled by that of a low-power standard oscillator B by means of a polyphase system which, when the two frequencies differ, causes a motor D to retune the transmitter A by turning the shaft S. Oscillations of standard frequency from the tank circuit 3, fed by the standard oscillator B, are applied to the control grids of valves V1, V2, V3, through phaseshifting impedances G, H, I so arranged that the grid-potentials differ by 120, as shown by the vectors G, H, I, in Fig. 2. Oscillations from the transmitter A which is to be controlled are applied, all in the same phase, to the plates of the valves V1, V2, V3 through condensers 22, 23, 24, and are represented by the vector T. The resultant vectors R1, R2, R3, will exhibit beats if the frequencies differ (i.e. if the vector T rotates faster or slower than the vectors G, H, I). These beats, which differ from one another in phase, are applied through transformers and amplifiers to a polyphase motor and relay 42, the stator 50, Fig. 3, of which produces a field whose direction of rotation depends on whether the frequency of transmitter A is too high or too low. The rotor 51 tends to turn in one direction or the other accordingly, and to close at 53 a circuit through one or other of the field coils F1 or F2, so that the tuning-shaft S is turned by the motor D in the required direction until the beats cease to have an effective frequency. The motor and relay shown in Fig. 3 may be replaced by a polyphase watt-hour meter ; artificial lines of different electrical lengths, as described in Specification 411,643, may be employed instead of the impedances G, H, I; and the transmitter A may comprise an oscillator of the kind described in Specifications 342,976 and 358,264.

In a two or four-stroke or rotary piston engine, Figs. 6, 7 and 9 (not shown), a lean mixture from a carburetter (152) is drawn into the combustion chamber 26 through an intake valve (158) or port (170, 178) and fuel is fed through the valve 60 to be vaporized in the tube 30 during the periods when the combustion chamber pressure is sufficiently low to permit the valve 60 to open. The rate of fuel flow to the tube 30 is set by restrictions, which may be adjustable, associated with the tube and the fuel supply pressure. The inner end of the tube 30 forms the centre electrode of a spark-plug which ignites the fuel vapour. The tube 30 may contain a tube (92), Fig. 2 (not shown), which is flattened at axially spaced regions, to increase heat transfer to the fuel. The tube 30 may include a constriction (98), Fig. 4 (not shown), to quench flame passing back along the tube. The spark electrodes may take various forms and the Specification discloses values for the air-fuel ratio of the carburetted mixture and the relative fuel quantities supplied vaporized and in the mixture under different operating conditions. The vaporized fuel may be petrol, alcohol or kerosene.

Patent GB-264237-A (GB)
Abstract: 264,237. Hatfield, H. S. Oct. 14, 1925. Disc recording apparatus; drum recording apparatus.-In an apparatus for automatically testing or analyzing liquids, a. record is made of the amount of reagent required to react with a known volume of the liquid. Fig. 1 shows an automatic apparatus in which a record is made of the amount of soap solution required to soften a known volume of water. Soap solution from a pipe G is added drop by drop to a known volume of water in a vessel E which is carried by an arm E<1> pivoted at E<2>. The liquid in the vessel E is agitated by air blown in at F, and the arrangement is such that when sufficient soap solution has been added a froth is formed which overflows from the vessel E and actuates apparatus whereby the vessel E is automatically tilted and emptied and finally refilled with another sample of water from a vessel C. The amount of scap solution used in each test is recorded as follows. Each drop of solution strikes a vane J and so breaks a contact K, de-energizes an electromagnet X, and, through a pawl U<1>, causes a toothed wheel U<2> to rotate. The wheel U<2> engages a wheel U<3> carrying a pen S. When, at the end of the analysis, the vessel E is tilted as described above, the arm E<1> strikes a contact P and so energizes an electromagnet V which lifts a retaining pawl W, and in this way the pen S is replaced at the zero position. A modified apparatus for recording the amount of reagent is described in which the reagent is delivered from a vessel having a float which operates a pen making a record on a disc, the vessel being automatically refilled to a constant level at the end of each analysis. Alternatively, the reagent may be supplied by a pump, the recording pen being operated by the motor driving the pump. The apparatus is suitably modified as regards the means for tilting and emptying the vessel E, when the reaction does not result in the formation of froth.

Title: Improvements in voltage regulators
Inventor: PINKNEY DESMOND REYNOLDS
IPC: G05F1/34
Filed: 1956-08-29
Abstract: 814,833. Rectifying; automatic voltagecontrol systems. SMITH & SONS (ENGLAND) Ltd., S. Aug. 29, 1957 [Aug. 29, 1956], No. 26430/56. Classes 38 (2) and 38 (4). A rectifying arrangement with a variable unidirectional voltage output comprises a singlephase bridge of dry plate rectifiers 3, 4, 6, 7 in series with the latter two of which are saturable chokes 8, 9, there being also an inductor 11 connected between the junction points of rectifier 6 and choke 8 and rectifier 7 and choke 9 and a variable resistor connected between the centre point of inductor 11 and the output terminal connected to rectifiers 3, 4. By varying the value of the resistor which may be a triode 12, the output voltage is varied. During the half cycle when rectifier 7 is conducting, choke 8, half inductor 11 and valve 12 are connected across the load so that choke 8 is saturated to a value determined bv the resistance of valve 12. During the next half cycle the load current which flows through choke 8 and rectifier 6 is determined by the degree to which it had been saturated. Similarly in the next half cycle the current flow is determined by the value to which choke 9 had been saturated in the half cycle when choke 8 was carrying the main load current. The coupling between the two halves of inductor 11 ensures that when choke 9 saturates the junction of rectifier 6 and choke 8 becomes negative to assist the flow of resetting current and reduce the magnitude of the reverse voltage against rectifiers 4 and 6. To maintain the output voltage at 5, 10 constant, the fraction developed across resistor 14 is compared at 15 with a standard voltage and a voltage proportional to the difference is applied to the grid of valve 12 as negative feedback.

Abstract: 484,202. Valve circuits for wireless reception. KALLMANN, H. E., and SPENCER, R. E. Sept. 30, 1936, No. 26474. [Class 40 (v)] A.V.C. voltages are derived from a television signal by displacing the synchronizing impulses so that the minimum amplitude of the resulting signal corresponds to minimum vision modulation and deriving a voltage corresponding to said minimum amplitude. The complete signal from the cathode resistance 21 of a V.F. amplifier 11 is applied through condenser 23 to the grid 26 of a valve 27 and also through resistance 31 to the grid 36 of valve 37. The valve 27 produces phase reversed synchronizing impulses at its anode which are applied through condenser 29 to the grid of valve 37 where they more than balance out the synchronizing impulses fed through resistance 31. Gain controlling voltage is taken from the cathode of valve 37 through filter 51, 53, 55, a diode 48, 49 being provided to prevent the production of positive control voltage. D.C. insertion may be provided in valve 27 by the method described in Specification 422,906.
