Patent GB-156818-A (GB)
Title: Improvements in automatic and distant control of aircraft or other dirigible bodies
IPC: F41G7/00
Filed: 1917-11-15
Abstract: 156,818. Hammond, J. H. Nov. 15, 1917. Distant control systems. - Comprises means for automatically maintaining aircraft in equilibrium and in a desired course, and for controlling the course from a distance by means of electromagnetic, light, sound, or other radiations. The valve 200 is capable of assuming six positions, being rotated one-sixth of a revolution at a time by step-by-step mechanism controlled by electromagnetic or other radiations. The radiations are received at 235, and close an electromagnetic switch 241, thereby energizing a solenoid 227 which admits air to a cylinder 211. The piston of the cylinder 211 rotates the valve 200 by rack-and-pinion and ratchet mechanism, the valve remaining in its new position while the piston is returned by a spring when the radiations cease. When the valve 200 is in its first position, or the fourth position at 180‹ ahead thereof, the course is maintained automatically. When the valve 200 is in its second position, a pipe 203 leading from the supply 199 is connected by the valve 200 with a pipe 365 leading to one end of a cylinder 350, the other end of which is open to exhaust by means of a pipe 367 and ports in the valve 200. The piston 351 is thus moved to the right and actuates cords 355 which produce an operation of the ailerons to bank the machine. At the same time, air is supplied also to the cylinder 375 by way of the pipe 202, valve 200, 'and pipe 376, thereby actuating the rudder to turn the machine to the right. Similarly, when the valve 200 is in its fifth position, the machine is steered to the left. During this actuation of the rudder, the arm 175 is unclutched from the gyroscope 55 by an air-pressure actuated device. For steering the machine up or down, the valve 200 is moved to its third or sixth position, in which air is admitted to one end or the other of a cylinder 318, the piston of which, by means of rack-and-pinion and ratchet mechanism, actuates cords 336 which effect an adjustment of the elevator.

Title: Facsimile recording apparatus
IPC: H04N1/16
Filed: 1945-07-06
Abstract: 595,574. Copying-telegraphy. FAXIMILE, Inc. July 6, 1945, No. 17293. Convention date, March 30, 1942. [Class 40 (iii)] In a facsimile recorder of the " lawn-mower " type, a helical electrode co-operates with a plurality of linear electrodes to produce a plurality of records of the transmitted copy, or records of a plurality of transmitted copies. A motor-driven drum 1 bearing a helical electrode 5 co-operates with three linear electrodes 6, 7, 8 (Figs. 1 and 2). Three sheets of chemically-treated paper 9, 10, 11 are fed between each of the linear electrodes and the helical electrode, and incoming picture signals are applied between the linear electrodes and the helical electrode to produce three records. As shown, the recording surfaces are spaced around the drum at 90 degrees intervals, and along the helix at 90 degrees intervals also, i.e. the helix is one of 540 degrees and the drum is one and a half times as long as a normal drum. The three recordings are therefore in phase. For other than a 90 degrees spacing of the linear electrodes around the drum, a corresponding longitudinal spacing is employed. In a modification (Fig. 3, not shown), picture signals from three transmitters are received on three carriers, amplified, filtered and fed to three detectors whose outputs feed three linear electrodes 6, 7, 8. Thus, each electrode, in combination with a helical electrode 5, records the modulation received from one of the transmitters. Instead of an electrolytic recording method, any method employing electrodes may be used.

Title: Circuit arrangements for eliminating ground return echoes in radar systems
IPC: G01S7/292
Filed: 1965-04-23
Abstract: 1,088,171. Pulse radar. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. April 23, 1965 [April 23, 1964], No. 17327/65. Heading H4D. Pulse radar apparatus is provided with means whereby clutter can be removed from an echo signal 1, Fig. 1b, without removing any target echoes protruding above said clutter. The echo signal shows three target echoes having a width T equal to the transmitted pulse width, two outside the area of clutter, and the third inside but of greater magnitude than the clutter. After I.F. amplification and detection at 11, Fig. 1a, the echo signal 1 is applied directly and with a delay T (waveform 2) to respective inputs of an AND gate 12. The output S1 of the gate has an amplitude equal to that of the lower of the two input signals. The output S1 is used as a first control signal, and is also applied to one input of a subtractor circuit 15 having the echo signal with a delay 2# (waveform 4) applied as the subtractor to its other input. The output of the subtractor circuit is such as to pass only positive signals, such that the output is S2, the second control signal. The first control signal S1 is used to control the attenuation of an attenuator 16, Fig. 2a (not shown), attenuating the I.F. echo signal 6, Fig. 2b (not shown). The variation of the attenuation is such that the clutter overlapped by the control signal is reduced in level to noise level, leaving an initial unattenuated portion of clutter, and the third echo signal (waveform 7). This waveform is then delayed by T and the remaing clutter portion removed by a second attenuator 18 under the control of the second control signal to give waveform 9, which after detection shows only the target echoes (waveform 10). In order that the arrangement described should have a dynamic range large enough to accept the full range of echo signals, I.F. amplifier 11 has a large dynamic range with a logarithmic amplitude response and the attenuators also have a logarithmic amplitude response.

[Also in Groups XXXV and XL (c)] A bridge circuit for effecting phase-modulation of an oscillatory voltage Ve comprises two branches a d b and a e b, of which the first comprises a losscontaining capacitative impedance Z3, and an equal loss - containing inductive impedance Z4; and the second comprises a fixed capacitative (or inductive) loss-containing impedance Z1, and a variable inductive (or capacitative) losscontaining impedance Z2, the latter including, for example, a reactance valve controlled by a signal voltage. In the vector diagram, Fig. 2, Va represents the output voltage, Ve the input voltage, and V1 ... V4 the voltages across the impedances Z1 ... Z4. As Z2 is varied, its phase angle is kept constant, and therefore the angle # between the voltages V1, V2 is constant; and if this angle is half the angle α between the voltages V3, V4 the output voltage Va is of constant amplitude throughout a wide angle # of phase shift.
