IPC: G01S1/02
Filed: 1956-02-21
Abstract: 825,009. Course recording apparatus. COMMUNICATIONS PATENTS Ltd. Feb. 21, 1956, No. 5376/56. Class 97(2) [Also in Group XXXVI] Apparatus for deriving polar co-ordinate data of a craft with respect to a reference. point comprises means to produce, in response to signals representing speed and compass heading, a first electrical signal representing the velocity of the craft directed along a radius vector from the reference point to the craft and a second signal representing the velocity of the craft in a direction at right angles to the radius vector, means to integrate the first signal to produce a further signal representing the range from the reference point and means to integrate the second signal divided by the range signal to produce a signal representing the bearing of the craft with respect to the reference point. In the apparatus shown # is the compass heading of the craft as received on a shaft 9 from the compass. # is the bearing, i.e. the angular polar co-ordinate, derived in a manner to be described and fed to a shaft 10. A differential 8 produces a rotation of the shaft 11 representing #-# which is used to rotate a potentiometer 7 fed with a voltage from an amplifier 6 energized by a signal representing the velocity V T  of the craft. The potentiometer produces voltages VTCos(#-#) and V T Sin(#-#) representing components of the velocity along and perpendicular, respectively, to the line joining the craft to the co-ordinate origin. The radial component is fed to the velodyne integrator 15 to produce a rotation of the shaft 16 representing range. This rotates a potentiometer 18 and a leadscrew 5 which moves a nut 3 radially over a chart 4. The voltage representing the tangential component is applied to the potentiometer 18 which is arranged to produce an output proportional to the product of the component and the reciprocal of range. This represents the rate of change of bearing which is integrated in the velodyne integrator 20 to produce a rotation of the shaft 21 representing the bearing #.This rotation is fed to the differential 8 and to the chart 4.

Title: Redundant triggering means for hv valve
IPC: H02M7/19
Filed: 1972-02-07
Abstract: 1376363 Firing series connected thyristors GENERAL ELECTRIC CO 7 Feb 1972 [12 Feb 1971] 5562/72 Heading H3T [Also in Division H2] In a switching arrangement comprising at least two simultaneously triggered thyristors connected in series, each having a series inductor for limiting the rate of rise of current and an auxiliary inductor connected in series with resistance across the limiting inductor to suppress transients, firing of both thyristors is ensured by auxiliary triggering circuits magnetically coupled to a respective limiting inductor or auxiliary inductor and effective to fire the other thyristor when the associated thyristor passes current. The Figure shows a high voltage switching circuit comprising two cells in series each including thyristors 2, 3, 4 and 5 shown with multiple gates to indicate that each may be replaced by a plurality of thyristors. A saturable inductor 6 limits the rate of rise of current in the cell and a saturable inductor 20 and resistor 17 together with diodes 18 suppress the commutating transients. Each winding 6 has an associated winding 44 coupled via a further transformer 47 to apply auxiliary firing pulses to the other cell so that if the main triggering pulse fails to fire the cell the auxiliary pulse is effective. To ensure auxiliary firing when the firing angle is short the connection between windings 44 and 46 can include a capacitor store circuit and a breakdown diode (Fig. 2). In addition transformers 47 may be omitted if the auxiliary firing pulses are coupled into the main firing pulse transformers 33. Inductors 21 and 22 protect thyristors in a cell if the adjacent thyristor fails to fire. Equalizing impedances 11-14 are provided, the capacitors of these impedances providing current to fire the cell if the adjacent cell has not fired. The main thyristor triggering circuit comprises a control system 23 coupled to pulse generator switches 25 via light links 26. Bridge circuits 27 are connected across the cells and when the cell is non-conducting allow capacitors 38 and 40 of respective pulse forming networks to charge. Operation of the switches 25 by the light link causes the network to discharge through the primary windings 32 to produce the firing pulses. Reference has been directed by the Comptroller to Specification 1,217,894.

Title: Improvements in and relating to speed indicators
IPC: G01P3/36
Filed: 1921-02-26
Abstract: 159,509. Suffit, R. M. R. Courtois-. Feb. 27, 1920, [Convention date]. Fluid speed indicators; impulse and momentum speed indicators; speed-indicator transmission mechanism.-The speed and number of revolutions of a revolving shaft are indisated and registered by mechanism receiving impulses, at a frequency dependent on the speed of the shaft, transmitted through a fluid such as air acting upon diaphragm chambers or other sensitive devices, the spindle of the speed-indicator being connected to a braking-device counteracting the impelling force due to the impulses. The apparatus may be applied to vehicles and aircraft to register speed and distance. In one arrangement, Fig. 2, an eccentric e on the revolving shaft oscillates a lever l bearing on a diaphragm m to vary the volume and pressure of air within a tube c leading to diaphragm chambers E within the casing of the instrument. The movements of the chambers E are transmitted to the ratchets s, s<1> of the counters by a rod b, pivoted frame d and pawl arms f, f<1>. The frame d also actuates an arm g to rotate a ratchet wheel J connected through a spring to another wheel l<1> gearing with a pinion on the shaft of a flyer p serving as a brake. The wheel l<1> runs upon a screw thread on its shaft and moves axially thereon to occupy a position dependent on the speed to be measured. It engages a part i connected by a spring N to a toothed sector W gearing with a pinion on the shaft of a disc V, which is provided with speed graduations read in relation to a fixed mark on the dial of the instrument. The part i may engage either of two flanges on the hub of the wheel l<1>. The variations of pressure within the tube c and the diaphragm chambers may be created by the actuation of an air escape or inlet valve in the tube by an eccentric on the rotating shaft, a continuous pressure or suction being set up by a fan driven from the shaft or by a Venturi arrangement on the vehicle. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter : Instead of a flyer, the disc V, Fig. 3 (Cancelled), may have sufficient mass to serve as a brake. A diaphragm pump with an inlet valve K, and an outlet valve W in the tube c opened periodically by an eccentric e on the shaft may be employed to create impulses. The utilization of air resistance in vehicles, and the employment of friction, liquid, centrifugal and chronometric brakes are also referred to. This subject-matter does not appear in the Specification as accepted.
