Title: Instruments for measuring the size and shape of surface irregularities
IPC: G01B7/34
Filed: 1939-02-16
Abstract: 523,436. Electric signalling systems. ABBOTT, E. J. Feb. 16, 1939, No. 5152. [Class 40 (i)] The size and shape of surface irregularities are measured by a tracer point which is moved over the surface so that its vertical displacements are measured by electrical means. The specimen 1, which is a surface of revolution, is rotated about its axis and an electromagnetic pick-up device 4, 5 is mounted on an arm 6, pivoted at 17, with a counterweight 8 so that the tracer point 2 causes the coil 4 to move in accordance with the contour of the tested surface. The voltage generated in the coil is passed through amplifiers and a weighting network to a cathode-ray oscillograph, which may be used in conjunction with a moving film to obtain a record of the surface contour. A running average indication of the height of the surface irregularities may be obtained by measuring the output voltage of the amplifier with an alternating-current voltmeter 20. The weighting network, which consists of series resistance and shunt condenser, is arranged to give an output inversely proportional to frequency. This is necessary since the voltage generated by the moving coil is proportional to velocity of displacement, whereas an indication proportional to amplitude of displacement is required. The mounting of the device may be modified to enable the inside of a surface of revolution to be examined, Figs. 8, 9, 10 (not shown). For examining a flat surface, the tracer head is provided with a large-radius pilot ball and is mounted on the end of a hinged arm which is moved by means of a screw mechanism, Fig. 5 (not. shown) ; or the tracer head may move in a guide parallel to the surface, Figs. 6 and 7 (not shown).

Abstract: 525,497. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and LUNT, R. W. Feb. 22, 1939, No. 5916. [Class 36] In order to render a high tension impregnated paper insulated cable resistant to breakdown the conductor or the outer part thereof is of aluminium or an aluminium alloy and has a chemically or electrolytically oxidized surface forming a thin and preferably continuous insulating coating constituting a protective layer. The coating is preferably formed by anodizing the aluminium surface of the conductor in a bath of electrolyte such as a 5 per cent. solution of oxalic acid or a 10 per cent. solution of sulphuric acid. The outer surface of the conductor may be formed of an aluminium foil wrapping, the coating being formed on the outer side. This may be done before the foil is applied to the conductor, precautions being taken to prevent the formation of an insulating coating on the side of the foil adjacent to the conductor. With this arrangement the conductor may be of copper or other metal. Where a conductor of aluminium or aluminium alloy is used, the protective barrier may be formed by treating the outer surface of the'conductor, or of each wire in the outermost and preferably in the underlying layer of a stranded conductor, to provide it with an insulating layer of oxide.

Abstract: 548,739. Exchange systems. JONES, C. E. P. May 14, 1941, No. 6216. [Class 40 (iv)] Dialling and other signals are received in voice-frequency form by a circuit whichexercises a volume-range compressing effect at the beginning and a volume-range expanding effect at the end of each signal for the correction of distortion. As shown, a biassing voltage obtained by rectifying the signal at RB is normally applied to network VA to cause it to produce a compression effect. When the signal has reached a level sufficient, with the help of amplifier TV, to operate the signal relay A, relay L operates to reverse the biassing voltage so as to put VA into the expanding condition. At the end of the signal therefore, the output of the receiving valve falls off rapidly and A is quickly released. Relay L falls shortly afterwards to restore the compressing condition.
