Abstract: 1,061,945. Load cells. PNEUMODYNAMICS CORPORATION. Dec. 1, 1965 [Jan. 6, 1965], No. 51028/65. Heading G1N. A load cell for incorporation e.g. in an aircraft axle 26 (Fig. 5), comprises a steel beam 10 rounded at one end 11, and squared at the other end 13, the intermediate portion 12 being tapered (see Fig. 1 (not shown) and accommodating two solid semi-conductor strips 16, 17 encapsulated in fused glass on opposite sides thereof. The round end 11 is clamped to the axle 26, and the stress in the cantilever-mounted beam 10 is adjusted by a screw 35 bearing on the square end 13 so that loading the axle, as by the weight of the aircraft when standing, reduces the stress in the beam and the semi-conductor elements, and is measured by the resistance of the elements connected in a bridge circuit.

Abstract: 1,248,975. Measuring rotation electrically. MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd. Nov. 1, 1968 [Nov. 2, 1967], No. 51819/68. Heading G1N. A rotation sensor, Fig. 6, comprises a rotatable member 1 carrying a rotary single pole double throw switch 2-7, so that a capacitor 11 is alternately discharged (contacts 5 and 7 made) and charged (contacts 5 and 6 made) from a second capacitor 12, the resultant voltage step at point 17 switching-on a transistor 14 which is maintained in a conducting state by charging current for the series combination of capacitors 11 and 12 being drawn through its base, the consequent variation of collector current providing a measure of rotational speed on a device 15, or the switching transition may indicate a cessation of rotation when the device 15 is a warning lamp or a relay coil. An alternative embodiment Fig. 11 is solely to indicate presence or absence of rotation. Above a critical speed, charging current for one or other of the capacitors 33, 34 is drawn through the base electrode of a transistor 28 of which the collector potential maintains a second transistor 30 in a cut-off state thus rendering a warning device 15 in its collector lead inoperative. Below the critical speed the capacitors become fully charged so base current to transistor 28 ceases thereby cutting it off and turning transistor 30 on, the resultant collector current activating the device 15. A by-pass switch 32 renders the circuit inoperative. Figs. 1-5 and 8-10 (not shown) illustrate details of the switch construction.

However the number of zero-crossings N over a given, relatively long, period T of S is the same as that of C 1  and this fact is utilized at the receiver Fig. 4 to afford angle # which is given by where f D  = frequency of C 1 , H = vertical path length at the beacon, f s  = frequency of repetitive movement of the radiation point, and # = carrier wavelength of the radiation (frequency f 1 ). For demodulation at the receiver a subcarrier of frequency (f 1 -f L ) may be radiated from a fixed point at the beacon or may be supplied by local oscillator 3. Discontinuities in waveform arise owing to abrupt reversals when the radiation point suddenly switches from its upper limit to its lowest point ("sawtooth modulation," Fig. 2 (not shown)) and are blanked out by causing the beacon to transmit a coded pulse group at the end of a sawtooth cycle.
