Patent GB-1100970-A (GB)
Title: Linear air-speed sensor
IPC: G01P5/00
Filed: 1966-09-21
Abstract: 1,100,970. Measuring air-speed electrically. AEROFLEX LABORATORIES Inc. Sept. 21, 1966 [Oct. 22, 1965], No.42111/66. Heading G1N. Apparatus for measuring the magnitude and direction of the air-speed of an aircraft comprises a probe 10 (Fig. 1) extending from an aircraft surface, having an axial duct 11 and a transverse duct 24, each containing bolometer resistors which, first cause the probe axis to be aligned with the air-flow direction, and secondly cause an impeller 12 in the axial duct 11 to be rotated at a speed which allows the air to leave the duct axially, this speed being proportional to the air-speed of the craft. The bolometer resistors 25, 26 in the transverse duct 24 are longitudinally displaced. When the axis of the probe is not aligned with the air-flow direction a pressure difference occurs between the ends of the duct 24 causing air-flow through it which differentially cools resistors 25, 26. The temperature difference is sensed by a resistance bridge whose unbalance energizes motor 30 to rotate the probe 10 to eliminate the unbalance, the resulting direction being transmitted by synchros to an air-flow direction indicator. The bolometer resistors 15, 16 in the axial duct 11 are symmetrically located about the axis. When the air-flow leaves the duct at an angle the resistors are differentially cooled. The temperature difference is sensed by a resistance bridge whose unbalance controls the energization of a motor 13 driving impeller 12 at a speed which allows the air-flow through duct 11 to be axial only. This speed is measured by a tachogenerator 21, 22 and indicated on a meter calibrated in airspeed. The apparatus may be mounted on a stationary member as an anemometer.

Convention date, July 5, 1934. [Class 38 (v)] A thermal switch for controlling a firealarm or other circuit comprises an elongated tube 10 of thin, expansible, material closed by end plugs 11 secured in place by solder. A resilient strip 13 of similar material is curved by compression between the plugs 11. In case of sudden heating, the tube expands more rapidly than the strip, so that the latter straightens. In case of slow heating, the tube and strip expand similarly. Alternatively, the strip may have a coefficient of expansion different from that of the tube. Preferably, a second curved strip 14 is provided of a material having a low coefficient of expansion. This strip is operative to control the circuit if slow heating is continued up to a predetermined point. The two strips are connected at the ends by conducting blocks 15. Terminal screws 22 having clip or other circuit connections 23 pass through holes in the tube 10 and are supported by insulating blocks 19, 21. They are connected electrically to adjustable screws 26 similarly supported by 'the blocks 19, 21. These screws normally are in contact with contact springs 25 carried by the strips 13, 14, which springs are carried away from the screws when either strip straightens. The strips may be connected in independent circuits. The switch may be arranged to operate in a normally open circuit, and to detect either rises or falls of temperature.
