Title: Radio location method
IPC: G01S3/48
Filed: 1972-03-22
Abstract: 1392343 Radio direction finding LICENTIA PATENT-VERWALTUNGS-GmbH 22 March 1972 [23 March 1971] 13483/72 Heading H4D To enable the signals from a plurality of transmitters possibly operating at different frequencies and with different modulation characteristics, to be separated out whereby the direction in azimuth and/or elevation of each of the transmitters may be determined, the signals are received by several broad-band receivers and the resultant sum signal there sampled at close intervals-e.g. at 2 MHz-over a period of time, to give a succession of amplitude values which, after digitizing, can be subjected to an orthogonal transformation whereby the frequency spectrum of the sum signal is produced in the form of a series of discrete components. By analyzing the spectrum, the components corresponding to the respective signals from the transmitters can be determined, and by comparing corresponding frequency components from the several receivers in amplitude and/or phase the directions of the various transmitters can be determined. Suitable orthogonal transformations are Fourier or Fast Fourier transforms, or a Matched Filter action.

Title: Improvements in and relating to prepayment mechanism for gas meters and the like
IPC: G07F15/00
Filed: 1939-05-06
Abstract: 530,511. Prepayment gas meters. ALDER & MACKAY, Ltd., and PEET, A. May 6, 1939, No. 13580. [Class 27] Prepayment mechanism for gas meters includes valve-closing mechanism comprising a cylinder with a circumferential slot co-acting with a pin on a long valve-operating lever so as to restrain the lever at all times and operate the valve rapidly at the appropriate times; the cylinder being driven from the combined prepayment and measuring-back mechanism. The illustrated form shows the application to a meter operable at will by two or more classes of coins in which a penny measuring-out wheel a drives a ratchet wheel c by means of a pawl and thus drives the pinion f of a coin ratio gear g. The latter drives the gear m fixed to the sleeve l and the rotation of the latter rotates the pinion n geared to the crown wheel u of the differential gear. The shilling measuring wheel i drives the ratchet wheel k on the sleeve l and so rotates pinion n directly and the penny pinion f indirectly through the gear g. When either of the measuring wheels is rotated, the ratchet-driven gear of the other wheel is rotated also, but not the measuring wheel itself. The rotation of the crown wheel u. on prepayment, rotates the crown wheel w in the reverse direction ; the planet carrier being held by the irreversible worm gear s. The rotation of w rotates the shaft x and (1) actuates gearing 2, 3 to operate a pointer showing the amount of credit and (2) causes the shaft to recede from the position in which the cam slot z actuates the lever system 6, 8 to close the meter valve. As the meter consumes gas, it drives the worm, gear s, and as the crown wheel u is held against rotation by the ratchet gear of the measuring wheels, the crown wheel w is rotated in the reverse direction to that which registers credit, the indicator shows the variation and eventuallv the lever 8 closes the valve and cuts off the supply.

Title: Improvements in or relating to railway axle counting equipment
Inventor: MULLARKEY ALFRED JOHN
IPC: B61L1/16
Filed: 1948-05-21
Abstract: 696,542. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd. May 21, 1948, No. 13786/48. Class 40 (vi). [Also in Group XXX] In railway axle counting apparatus means are provided whereby signals from the two incoming channels for the signals denoting the entry, unrelated in time but by chance possibly simultaneous, of axles at the two ends of a track section are so transferred that only one entry signal at a time can be passed to the single outlet for these entry signals; like arrangements are provided for the signals from the incoming channels denoting the exit of axles at the two ends of the track section. A signal not at once transferred to the appropriate outlet is stored and transferred immediately afterwards. The signals are thus " gated " and all in turn are passed to the translating means. The simultaneous entry (or exit) signals may occur due to the buffering of the vehicles in a long train extending through the track section. At each end of the track section means are provided, responsive to the direction of travel, to actuate an in-counting contact 9 or 11 or an out-counting contact 10 or 12 by which a corresponding condenser 13 is charged the voltage of which is applied to the anode of a gaseous discharge tube 5 or 7, or 6 or 8, the grid of which however only has sufficient voltage applied thereto to fire the tube when a peaky wave derived from a squarewave generator 1 through a circuit 4 applies sufficient voltage. The in-counting at the other end of the track section is similarly effected but by the other half wave of the generator 1, i.e. at a time interval of 180 electrical degrees. Thus, simultaneous in-counting signals from the two ends of the track section will operate the translating means in a timespaced manner. The " in " and " out " pulses of the discharge tubes 5, 7 and 6, 8 are respectively applied to limiter circuits 18 and 19 which give standard amplitude pulses to a double tube cathode follower circuit 14 feeding the leads 15, 16 to the " in " and " out " sections of the tranlating apparatus. If four signals are required to be gated to a single outlet a square-wave generator giving four outputs in quadrature is used; if a higher number of signals are to be gated a corresponding number of phases is used. Simultaneous in- and out-counting at any one end of the track section cannot occur since an axle cannot be moving in both the " in " and the " out " directions simultaneously. Specifications 683,022, [Group XXX], and 696,543 are referred to.

Class 52(1) The top wall of an oil-burning convector heater has a carrying handle mounted on a stem slidable in the top wall so that, in the out of use position. the handle lies on the top wall but, for carrying, it can be pulled up to give finger clearance between the handle and wall. As shown, handle 2 is moulded on to two threaded studs 6 to which are screwed spindles 4 surrounded by plastic coverings 7. The spindles are received in holes 8 in top wall 1 and are connected within the heater by a stout wire 10 which prevents removal of the handle and unscrewing of the spindles from the studs. Alternatively the stems may comprise bolts the heads or nuts of which retain them on the heater. In a modification the handle may be mounted on a single stem, the stem and the hole in the top wall being non-circular to prevent roatation.

Title: Arrangements for the frequency modulation of a high-frequency oscillation
IPC: H03C3/20
Filed: 1942-10-06
Abstract: 561,323. Automatic control systems. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Oct. 6, 1942, No. 14016. Convention date, Oct. 28, 1941. [Class 38 (iv)] [Also in Group XL]. An arrangement for the frequency modulation of a high-frequency oscillation, consists of at least one oscillatory circuit, which comprises at least one condenser with mechanically non- displaceable coatings and a mechanically non-displaceable blocking layer, the capacity of which is dependent upon a bias voltage and to which a lowfrequency control voltage is supplied, so that the tuning varies in accordance with this lowfrequency voltage. Fig. 1 shows a valve V arranged as a back-coupled oscillator, the frequency of which is determined by an inductance L and adjustable condenser C shunted by a potential variable condenser K of the blocking layer type. The output, taken at 3, 4 is at a frequency which is variable in accordance with fluctuations in a voltage e which is applied at 1, 2 through a high-frequency choke L0 to vary the capacity of condenser K. The invention is also applicable to oscillators in which the tuned circuit has Bee point connection to the electrodes of the valve, Fig. 2 (not shown), while in a further embodiment, the fluctuating control potential is applied directly across the potential variable capacity, Fig. 3 (not shown). Fig. 5 shows the invention applied to a frequency modulation transmitter comprising a generator G, the output of which is modulated by a microphone M by means of an amplifier A1 applying a voltage to a potential variable condenser forming part of the frequency determining circuit Q of the generator. The output from G is passed through a frequenoy doubler F and amplifier A2 to the aerial. In order to keep the mean frequency constant, the output from F is heterodyned at M1 to give a difference frequency which is fed to a discriminator circuit D which produces a voltage which varies in magnitude and sign according to deviations of the difference frequency from its assigned value. This voltage is fed to the potential variable condenser at Q to maintain the frequency constant.

Patent GB-140655-A (GB)
Abstract: 140,655. Automatic Telephone Manufacturing Co., and Ray, A. J. May 23, 1919. Automatic and semi-automatic exchange systems.-A single switch, similar to those used by ordinary subscribers, is available both to a test clerk and to trunk operators for setting up testing and trunk-offering connexions respectively, the toll operators having exclusive preference so that a testing-connexion can be broken down in favour of a trunk-offering connexion. In the system described, a Strowger connector C, which is not provided with busy-test or ringing apparatus, is accessible from a trunk operator's jack B and from the test clerk s jack A. Control of connector by test clerk. The insertion of a plug in jack A lights the supervisory lamp L' and energizes the connector impulse relay 10, which closes the circuit of the usual slowrelease relay 19. The connector wipers are then brought in known manner to the terminals of the line to be tested. If the line is free, relays 24, 23 are energized, relay 23 opening the circuit of lamp L<1> and bringing into circuit its low-resisttance winding 27 so as to mark the selected line as busy, the test wiper 31 being connected to this circuit over contact 28 of relay 24. If the line is busy, the relay 23 is short-circuited and the lamp L<1> remains lighted. To test the line, the clerk depresses the holding-key 32, thereby energizing relay 18, which connects a resistance R to the impulse relay 10 to keep this energized, and by closing contacts 38, 39 extends the wipers direct to the circuit of the test plug. The cut-off relay of the selected line is energized over the test wiper so as to disconnect the exchange apparatus of this line; if, however, it is desired to test the exchange apparatus, the circuit over the test wiper is interrupted by a key in the sleevecircuit of the test plug. Control of connector by trunk operator. The insertion of a plug in jack B by the trunk operator energizes the impulse and release relays 10, 19 in the usual way, and also a relay 37 which lights a busy lamp L<2> at the test position and closes a circuit for relays 13, 45. Relay 45 energizes a relay 34, and relays 13, 34 disconnect the leads to the testing-jack A. The connector wipers are adjusted in the usual manner, and when the side-switch arm 1 reaches its third position, a circuit is closed for relay 54, which completes the speaking circuit shown in thickened lines. If the connector is in use by the test clerk when the trunk operator inserts her plug in jack B, the energization of relays 37, 13, 34 disconnects all the test circuits and releases the connector.

Title: Gyroscopic stabilising apparatus
IPC: F41G5/16
Filed: 1943-08-30
Abstract: 657,669. Self-levelling arrangements. KUIJVENHOVEN, A. W. Aug. 30, 1943, Nos. 14150 and 20314. [Class 113 (i)] [Also in Groups XX, XXI and XXXVIII] Gyroscopic stabilizing apparatus of the kind described in Specification 657,668, comprises means for resolving the stabilizing impulses provided by such apparatus into corresponding impulses with reference to a system of axes differing from that with respect to which impulses are given directly to the unit itself. The base B, Fig. 2, of the stabilizer unit is pivotally mounted on a second base B<SP>1</SP> about an axis A<SP>13</SP> which coincides with the vertical axis A<SP>3</SP> of the stabilizer unit when both bases are horizontal. The base B<SP>1</SP> is adjusted relatively to base B by a motor S<SP>13</SP> and a transmitter T<SP>13</SP> measures their relative displacement. A gimbal frame F<SP>5</SP>, pivotally connected to frame F<SP>1</SP> of the stabilizing unit about axis A<SP>3</SP> is pivotally mounted about an axis A<SP>12</SP> within an outer gimbal frame F<SP>6</SP> which in turn is pivotally mounted about an axis A<SP>11</SP> in brackets B3 mounted on the base B<SP>1</SP>. Relative movements between frames F- and F' and between F- and the base B<SP>1</SP> are imparted by gearing WT<SP>12</SP> and WT<SP>11</SP> to transmitters T<SP>12</SP> and T" respectively. These transmitters thus provide stabilizing impulses about axes A<SP>11</SP> and A<SP>12</SP> in the same way as transmitters T<SP>1</SP> and T<SP>2</SP> with respect to axes A<SP>1</SP> and A<SP>2</SP> as described in Specification 657,668. Similarly transmitter TO<SP>3</SP> provides stabilizing impulses with respect to axis A<SP>3</SP>. These impulses are given to the apparatus to be controlled and stabilized by power motors responsive to these transmitters by mechanical or electrical means (see Group XXXVIII). In a modification, Fig. 6, the brackets B3, in which the frame F<SP>6</SP> is pivoted, are mounted on the base B and the axes A<SP>1</SP> and A<SP>11</SP> are coincident. The frame F<SP>5</SP> is pivoted about an axis A<SP>12</SP> within a frame F<SP>7</SP> rotatably mounted within F<SP>6</SP> on ball bearings 28 and can rotate with respect to F<SP>6</SP> around an axis A<SP>23</SP> which coincides with A<SP>3</SP> when the base is horizontal. Motor S<SP>23</SP> through gearing 35-36 adjusts F<SP>7</SP> relatively to F<SP>6</SP> and their relative displacement is measured through gearing 37-36 by transmitter T<SP>23</SP>. Stabilizing impulses in the second system of axes are therefore given by T", T<SP>12</SP> and T<SP>03</SP>, as before.
