Title: Position-Measuring Apparatus
IPC: G01D5/20
Filed: 1967-10-26
Abstract: 1,179,754. Measuring displacements electrically. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct.26, 1967 [Oct.29, 1966], No.48693/67. Headings G1A and G1N. The position or variation in position of a linearly movable object is measured by a device comprising a rotating disc 5, Fig. 1, provided round its circumference with strips 1 having the form of involutes whose common evolute is a circle 2a contacting a line 2 along which equally spaced marks 3 of a gauge movable with the body, are arranged. The disc 5 is rotated at a constant speed and the relative position of the strips and marks is sensed using an inductive or capacitative pickup or optically to produce an A. C. signal whose phase is indicative of the position of the gauge. As shown, Fig.2, the pickup comprises a permanent magnet 8 surrounded by a coil 9, the marks 3 and strips 1, which are formed of magnetically permeable material, being arranged in a magnetic circuit 12 to vary the air gap dependent on their presence or absence. The A.C. signal generated in the coil 9 may be compared with a reference A. C. signal, in phase with the output signal for a given position of gauge and disc, to determine the phase difference and variation in position of the gauge. Alternatively the A. C. signals generated by two pickups (15), (16), Fig. 3a (not shown) associated with the gauge (14) arranged at either end of a diameter of the circuit 2a, may be compared in phase, a phase difference of 360‹ resulting from a movement of half a pitch of the gauge. To correct for the effects of the eccentric mounting of the disc, which produces an additional phase difference between the outputs of the two pickups, dependent on the angular position of the disc, the angular position of the disc is sensed inductively by pickups (23), (24), Fig.5a (not shown) which detect the presence of marks (24) of magnetic material arranged concentrically on the disc 5 and having the same pitch angle as the strips. The two output signals from these pickups also have the same phase difference as that of the outputs of pickups (15), (16) produced above by eccentric mounting of the disc, the signals being used to eliminate the effects of this phase difference from the outputs of pickups (15), (16).

Title: Fat hydroperoxides
IPC: C09K23/00
Filed: 1963-12-10
Abstract: Aerosol compositions comprise a hydroperoxide of a fat which is an ester of an unsaturated fatty acid with glycerol or a mono- or poly-hydric alcohol which may or may not be fully esterified having at least one ethylenically unsaturated fatty acid radical containing from 10-22 carbon atoms in the fatty acid chain, and having an iodine number of from 50 to 150, the hydroperoxide having a peroxidation value of at least 20, or aqueous emulsions of these hydroperoxides, and conventional propellants, e.g. hydrocarbons, perfluorinated hydrocarbons, fluorochlorohydrocarbons and mixtures thereof.ALSO:The Specification claims as a novel compound a hydroperoxide of a fat which is an ester of an unsaturated fatty acid with glycerol or a mono- or poly-hydric alcohol which may or may not be fully esterified having at least one ethylenically unsaturated fatty acid radical containing from 10 to 22 carbon atoms in the fatty acid chain and having an iodine number of from 50 to 150, the hydroperoxide having a peroxidation value of at least 20, and the preparation thereof by subjecting the fat to the action of oxygen and/or a substance producing peroxide radicals at a temperature and for a time which is sufficient to obtain a hydroperoxide having a peroxidation value of at least 20, but which precludes the formation of autoxidation products. The peroxidation value is a measure of the number of gram-atoms of peroxide oxygen present in a compound, the value of 100 corresponding to the presence of one-half gram-atom of peroxide oxygen per 1000 g. of compound. These hydroperoxides spontaneously form ultramicroscopic emulsions when introduced into water having a pH of at least 7.  Therapeutic compositions useful in the treatment of conditions which produce ulcerative or other abnormal conditions on the skin or other organs accessible to topical application, e.g. dermatosis, burns, bedsores, varicose ulcers, neoplastic ulcers, leprosy, cancer and toxaemias, and of pulmonary diseases, e.g. tuberculosis and silicosis, and of various asthenic states, and which may be administered orally, topically or parenterally, contain as active ingredient a hydroperoxide as described above. Cosmetic preparations comprise a stable aqueous emulsion of the hydroperoxides described above in association with the usual adjuvants.

In a cathode-ray tube in which the length of the tube is reduced by having the neck out of alignment with the rest of the envelope and in which the electron beam from gun 3 is deflected in two mutually perpendicular directions at right-angles to the beam path, the beam is bent towards the screen 8 by a pair of plates 5 each of which is curved to form part of a cylindrical surface and situated so that the corresponding cylinders are coaxial, and each surface subtending an angle # at the cylinder axes, which angles are coincident, and where # lies between 127À3 and 133 degrees. Preferably the deflection of the electron beam in the axial direction of the cylinders 5 is effected by plates 4 situated between the cylinders and gun 3, and deflection of the beam in the radial direction of the cylinders is effected by plates 6 after the beam has passed through the cylniders. The upper limit on the angle 0 is imposed by restricting the magnification in the radial direction of the cylinders of an image after passing through the cylinders to being not less than 0À5, and furthermore the distance L from the end plane 10 of the cylinders to the first focus of the beam becomes so large for angles greater than 133 degrees that no significant reduction in the length of the tube is achieved.
