Abstract: 1,086,475. Testing seats. PRESSED STEEL FISHER Ltd. June 15, 1966 [May 31, 1965], No. 23149/65. Heading A4M. A seat is tested by subjecting predetermined zones of its supporting surface to known loads and measuring the resulting deflections. The load is applied vertically through deflecting means shaped to represent the buttocks and the small of the back of the user. The results of the test are used to derive the deflected profile and the spring rate at predetermined zones. A hysteresis loop is derived from deflections corresponding to applied increments and decrements of load. Deflections may be measured against a time basis in actual or simulated movement of a vehicle.

Filed: 1946-08-08
Abstract: 601,442. Frequency modulation. SOC. FRANCAISE RADIO-ELECTRIQUE. Aug. 8, 1946, No. 23597. Convention date, June 11, 1942. ,[Classes 40 (v) and 40 (vi)] [Also in Group XL (a)] A frequency-modulated decimetric wave apparatus comprises a frequency changer in which unmodulated decimetric waves are mixed with frequency-modulated metric waves to give frequency-modulated waves at the sum or difference frequency. In one embodiment, the output of a diode frequency changer is coupled to the input cavity of an amplifying velocitymodulated valve tuned to the required frequency. In another embodiment, the frequencymodulated metric waves are applied to the density grid of a velocity-modulated valve, the input cavity of which is excited by unmodulated decimetric waves, the output cavity being tuned to the required frequency. In a modification, a velocity-modulated valve having three resonant cavities is used, the first two cavities from the cathode being loosely coupled to act as a generator of unmodulated decimetric waves, and the third cavity being tuned to the required decimetric frequency. As applied to a radio relay station, the frequency-modulated metric waves applied to the density grid of the frequency changer are obtained by mixing the incoming F.M. decimetric waves with the output of a local oscillator, which also provides decimetric waves to excite the input cavity of a velocity-modulated mixer valve. The output cavity of the mixer is tuned to the sum or difference of the I.F. and local oscillator frequency, according to whether the local oscillator frequency is higher or lower than the received frequency. A small amount of energy at the received frequency appears in the output cavity of the mixer valve, and may be used for negative back coupling.
