Abstract: 1535197 Magnetic field sensor SONY CORP 23 Dec 1975 [29 Dec 1974] 52650/75 Heading G1N [Also in Division G4]  A magneto resistive element 1 having two mutually perpendicularly disposed ferromagnetic strips A, B on an insulating substrate, is bonded to a bias magnet 12 providing a magnetic field H 1  directed orthogonally to the main current conducting paths 2B of one of the strips. Proximity of a member 13 of relatively high magnetic permeability e.g. soft iron, to the combination 10 of the element with the magnet induces a magnetic field H 2  in the member. The resultant field H 0  passing through the element is a function of the proximity of the member to it. The element may be connected in a bridge circuit to provide an output signal e o  indicative of displacement of the member. Alternatively, Fig. 11A (not shown) the combination 10 may sense displacement of the member 13 to provide a contactless switching function with a relay (19) providing an indication. The combination 10 may be used with a soft iron strip (20) having apertures (21) as a speed or displacement detector, Fig. 12 (not shown). Provision of a second, offset row of apertures as T 1 , T 2  with a second detector combination allows direction of displacement to be determined also.

Abstract: 1,156,419. Determining contaminants in liquefied gases. BRITISH OXYGEN CO. Ltd. 27 Nov., 1967 [28 Nov., 1966], No. 53086/66. Heading B1X. A liquefied gas containing a contaminant whose concentration is to be estimated is passed into closed vessel 11by tube 21 until a predetermined amount,corresponding to the liquid level when tube 21 just touches the surface, has been introduced. Tube 21 is then closed. Heat inleak from the surroundings causes the liquefied gas to evaporate through an adsorbent in tube 25 which specifically adsorbs the contaminant. When all the liquid has evaporated, the vessel is flushed with inert desorbing gas as the temperature is allowed to rise, until all the adsorbed contaminant has been desorbed. The desorbing gas stream contaming the contaminant is suitably passed into a colorimetric reagent, e.g. Ilovsay's reagent in the case of acetylene, by means of which it may be quantitatively determined. In this way, carbon dioxide, and especially acetylene, content may be determined in liquid oxygen, air or nitrogen, or a mercaptan in a liquefield hydrocarbon, using alumina, a molecular sieve, or preferably silica as adsorbent, and nitrogen or argon as the inert gas. In the case where both acetylene and azone are present as impurities in liquid oxygen or nitrogen, the adsorbent is preferably palladised or platinised to convert the ozone to oxygen before the actylene is estimated.
