Abstract: 889,594. Aircraft instruments. KELVIN & HUGHES Ltd. March 24, 1959 [March 24, 1958], No. 9331/58. Class 40 (1). Data such as air speed, altitude, rate of change of altitude and Mach number are derived from the output shafts of two pressure transducers of the type described in Specification 889,595. In Fig. 2 pressure transducer 80 is fed with pitot and static pressure and the output shaft position forms signal 82 which is proportional to Pitot- Static pressure this is corrected at 85 for Probe position errors to form " corrected P-S " signal. A second transducer 83 is fed with static pressure only and produces a signal which, corrected for probe position errors at 90, gives " corrected S " signal. Air speed indicator 88 is driven via a data transmission system 87 from cam 86 which is of a form to give a log (P-S) signal from the corrected P-S signal. Altimeter.-The corrected P signal is compensated for ground pressure by a second input to differential 107 from a manual adjuster 93 and the compensated signal fed, via data transmission system 92, to indicator 93 calibrated to read altitude directly. Rate of change of height is obtained by driving a tacho generator with the " corrected P signal " and indicated on 100 via data processing and transmission system 97 and 99. Mach number M.-Computer 101, fed with. (P-S) and S signals, evaluates M<SP>2</SP> from the P-S equation M<SP>2</SP> = - cam 103 gives an output S  shaft position proportional to M which is indicated on 104 via data transmission system 105.

Title: Improvements relating to apparatus and systems responsive to the intensity and direction of a magnetic field
IPC: H02K24/00
Filed: 1941-07-30
Abstract: 599,428. Flux gate compasses. PURVES CORPORATION. July 30, 1941, No. 9715. Convention date, July 30, 1940. [Class 40 (i)] [Also in Groups XXXV and XXXVI] Apparatus responsive to the direction and intensity of a magnetic field, for example an inductor compass, comprises a highly-permeable magnetic core 1 having poles 2, 3 for fluxcollecting and extensions 2<1>, 3<1> forming an auxiliary magnetic circuit at each end. Windings 4, 4<1> are energized from an A.C. source 7<1> in such a way as to magnetize the core equally and oppositely so that, with no external field, a slidable secondary 5 is unenergized. When, however, the core is subjected to an external magnetic field, as shown by the arrows, the periodic flux set up by coils 4, 4<1> opposes and assists the external flux in the respective ends of the core, according to the half-cycle of the A.C. source 7<1>. The theory is given in Figs. 4, 5 (not shown), but the effect is to produce in the secondary 5 a double-frequency current which, in Fig. 2, is compared in a phase detector 14, which may be as described in Specification 473,753, with the standard supply from source 7<1> passed through a frequency-doubler 15, which may be similar to that shown at 15<1> in Fig. 3. According to which side of the null position the inductor axis lies, so the phase of the output of coil 5 causes one or other winding 17 to move armature 18 to contact 19 or 19<1> so driving a motor 12 and hence the disc 11 carrying the inductor until the latter is again in the null position, whereupon no more signal is applied to relay 17 and the motor comes to rest. In Fig. 3, the device 15<1> is in the form of a full-wave rectifier circuit with condensers 16, 161 to block the D.C. component of the output, leaving the double-frequency currents free to energize the rotor 37 of a "selsyn" receiver. Three equi-angularly-arranged bars 20 ... 22, each having a set of coils as in Fig 1 have their secondary windings 27 ... 29, which generate potentials proportional to a component of the field, connected over lines 30 ... 32 to coils 34 ... 36 of the receiver 33, whereby the rotor 37 aligns itself with the resultant of the three components. The rotor is shown connected to a compass card 38, but may alternatively be connected rigidly to a power-driven object which is to be aligned with the field and the receiver 33 then utilized as a " selsyn " generator to generate a voltage proportional to the misalignment of the object with the field for controlling the driving means. The output of the coil 5 may be connected directly to a central-zero indicator, Fig. 6 (not shown), or to the movable coil of a dynamometer instrument having its fixed coil fed from an A.C. source, Fig. 7 (not shown).

Abstract: 706,458. Control of several motors. WESTERN ELECTRIC CO., Inc. April 18, 1952 [April 19, 1951], No. 9804/52. Class 38(3) [Also in Group XXII] Closure of the start switch 495 in the control circuit of a machine for clinching terminal tags at spaced points along electrical conductors (see Group XXII) energizes first the main drive motor 109 and then a conveyor motor 120 for forward running. A centrifugally-operated plugging switch PS109 is fitted on the motor 109 and on rotation of the motor, closes and prepares the circuit for reverse running of the motor when the coil M109F is later de-energized. Near the end of a cycle of operation of the machine, a limit switch 476 is momentarily closed to cause a motor 431 to run for a short period to take up slack in the conductors and, at the end of a cycle, a limit switch LS480 having several contacts is operated to disconnect the supply to the motor 109, de-energize the coil M109F and, through the plugging switch PS109, to reverse the current to the motor and plug it quickly to a stop. As a result of the stopping of the motor 109, the switch PS109 is opened and breaks the circuit to a control relay CR4 which closes contacts to provide current for forward running of a motor 457 for feeding long lengths of conductors between each cycle of operations. A centrifugally-operated plugging switch PS457 is closed by rotation of the motor and prepares the circuit for plugging the motor to a stop when a switch 465 is operated by a tuning device.
