Title: Method and apparatus for detecting shape of flat products
IPC: G01L5/107
Filed: 1973-09-24
Abstract: 1405207 Electro-physical measurement - flatness NIPPON STEEL CORP 24 Sept 1973 [29 Sept 1972] 44617/73 Heading G1N [Also in Division G3] To measure the flatness of nominally flat strip material 11, (such as sheet steel from a cold rolling mill), it is held under tension between rolls 12 and deflected at right angles to its planes by the electromagnetic force from pulsed inductors B. The deflection of the strip is detected by a plurality of capacitor plates mounted transversely below the strip. The signal processing circuit 19 for each capacitor is substantially self-explanatory as shown in Fig. 2 and the output may be applied to a CRT display 21 and or an automatic mill tension control. Integration of the deflection signal in synchronizm with the electromagnetic excitation effectively averages out signals due to waving movement of the strip. The Specification shows that the integrated signal gives a more linear response and is substantially proportional to tension. Instead of a rectangular wave as used in Fig. 2, a random signal or sine-wave may be used. In such cases the deflection signal may be multiplied by the exciting signal.

Title: Cracking process
IPC: C10G69/06
Filed: 1961-12-14
Abstract: In the pyrolysis of liquid hydrocarbons to obtain gaseous olefins and a cracked gasoline, the latter is hydrogenated under conditions which hydrogenate the diolefins while leaving unchanged mono-olefins and aromatics, the aromatic compounds are removed and the non-aromatic material is recycled to the pyrolysis. The hydrogenation is effected over a palladium or nickel catalyst in the liquid, e.g. trickling, phase at below 100 DEG  C. with palladium catalyst and below 200 DEG C. with nickel.  The pressure may be 20-80 atmospheres. In a preferred embodiment material boiling below benzene, e.g. below 75 DEG  C., is removed by distillation and recycled to the pyrolysis. The remainder is further hydrogenated to convert olefins to saturated materials without affecting aromatics e.g. in the liquid phase over cobalt molybdate or molybdena on alumina at 250-400 DEG  C., 10-60 atmospheres and 0.5-3 kg. of feed per litre of catalyst per hour. Aromatics are separated, e.g. by solvent extraction with aqueous diethylene glycol, and recovered as a product and the raffinate is returned to the pyrolysis.

Abstract: 1495057 Detecting pollution using Raman Spectra ALLIED CHEMICAL CORP 17 Nov 1975 [26 Nov 1974] 47287/75 Addition to 1436238 Heading G1A In a pollution monitoring apparatus for the spectroscopic detection and quantitative measurement of constituents of a gas or vapour, wherein light having a spectrum in which lines are periodic in frequency (i.e. a Raman Spectrum) is investigated, two interferometric means are used. The interferometric means are adapted to receive the light and to separate a selected spectrum therefrom by providing a plurality of transmission peaks or windows regularly spaced in frequency. A Raman spectrum is that due to the rotational or vibrational effects of the molecules making up the sample. Each molecule shape has its own spectrum. A monochromatic, coherent, collimated beam of pulsed radiation from a laser 36 is directed into the sample 40 and the scattered radiation is directed via a lens through two "Fabry-Perot" interferometers 15, 16. The emergent radiation intensity is mainly due to the rotational Raman spectra of a pre-selected constituent of the gas to be monitored (e.g. carbon dioxide). It is focused by a lens 46 on to a pinhole stop 48 in front of a photomultiplier 50. The electrical output is fed to a phase sensitive detection means 52 (lock-in amplifier) along with the output of a modulating means 42. The modulating means 42 modulates the phase difference of the interferometer 16, or 15 (as described in the above mentioned patent). The output of the phase sensitive detector 52, which is proportional to intensity variations of the modified fringe chosen for analysis, is displayed by an oscilloscope and a chart recorder. The frequency spacing between adjacent peaks of the second interferometric means 16 is adjustable to reject interfering lines having a frequency in the vicinity of the frequency of the rotational Raman lines of the selected spectrum and that have been transmitted by the first interferometric means. The ratio between the spectral range of the second interferometric means to that of the first interferometric means is adjusted to approximate a ratio of odd numbers and is greater than unity. The use of a pulsed laser 36 together with a time gated electronic detection system permits pollution monitoring at a sample considerably remote from the apparatus. By measuring the time interval required to send a laser pulse to a sample and to receive a return signal and by measuring the amplitude, the distance away and the pollution concentration can be obtained. Detailed formulae and a mathematical explanation are disclosed.
