Abstract: 1278843 Heat treating apparatus ICHIKIN KOGYOSHA KK 11 March 1970 [13 March 1969] 11778/70 Heading D1L Apparatus for heat treating a fabric, as shown, wherein a fabric a to be treated is fed into the heating chamber 1, and travels through the chamber by feed rollers 2. In the chamber the fabric hangs down to form loops b between adjacent rollers, and is treated with steam projected onto the fabric from projectors 12 inside the loop and 18 below the loop. During treatment the loop is lifted by the projecting stream, so that the fabric a is substantially free from tension, and the portion of the fabric in contact with the roller, is held in close contact with the perforated surface by a vacuum created from inside the roller. The apparatus is suitable for continuous heat treatments such as, steam baking, thermosol colouring, and heat drying.

Title: Single-cell digital stress sensor

Filed: 1973-03-15
Abstract: 1428175 Stress sensor OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES and LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 15 March 1973 [28 March 1972] 12562/73 Heading H3H A stress sensor comprises a small, thin film of anisotropic magnetostrictive material mounted on a larger resilient substrate such that a stress applied having a component normal to the plane of the substrate is transmitted to the film, two interrogation conductors mounted at right angles to each other in the plane of and across the film and supplied respectively with two trains of short duration rectangular pulses whose amplitudes reproduce simultaneously sampled values of two sinusoids of equal amplitude and frequency which are #/2 out of phase with each other, and a further conductor also crossing the film and connected with read-out circuitry responsive to the sense of pulses induced in the read-out conductor. The axis of magnetization of the thin film is caused to rotate by the application of the stress and the two interrogation pulse trains produce a pulsed magnetic field the direction of which changes step-wise through an angular range determined by the angular range of the sinusoidal generator. At the point where the imposed field becomes perpendicular with the rotated axis, the read-out pulses change polarity, and by correlating the angle of the applied field at this instant with the non-rotated axis, the stress may be determined. As shown, the preferred embodiment comprises a square-wave oscillator 11 driving a divide-by-2 circuit 10, the output of which is taken to divide-by-n circuit 14, the number n being the number of discrete angular steps occupied by the applied field in one cycle. The oscillator 11 output is taken with the output from divider 14 to a gating circuit 12, the output of which is a pulse at each change of polarity of the divided signal from 14. Each pulse from 12 triggers an integrator 13 which enables a sine wave generator to produce a first “ cycle of a sinusoidal wave. The output from 15 is taken to sample-and-hold circuit 16 where sampling pulses from AND gate 20 are applied, which pulses occur during negative ¢ cycles of the output from divider 10. A stepped wave is thereby produced at 16 which is fed to a gate 17 which is enabled by pulses derived from the sampling pulses by being delayed by 1 period of the output of oscillator 11 at monostable 21, which triggers one shot 22. A #/2 phase shifter 19 is also provided and the required pulse trains are thereby applied to orthogonal leads 3, 4. The output from read lead 5 is taken via amplifier 30 and gate 31 to set or reset flip-flop 33, the change of polarity of the output Q being indicative of the instant the applied field is orthogonal to the rotated axis of magnetization.
