Title: Improvements relating to ferro-magnetic metals
IPC: C21D8/12
Filed: 1948-09-01
Abstract: 658,425. Electrolysis. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, and EPELBOIN, I. Sept. 1, 1948, Nos. 23098 and 23099. Convention dates, March 8 and July 9. [Class 41] A method of manufacturing electromagnetic cores or other electromagnetic elements formed of sheets or bands of ferromagnetic materials comprises decreasing the section of such sheets or bands by electrolytic polishing so as to improve their electric and magnetic properties and thereafter forming the core or the element. In order to decrease energy losses, such as those due to convection currents, the section should be decreased by less than 10 per cent, but to increase the permeability the section should be decreased by more than 10 per cent. After electrolytic treatment and before assembly the sheets or bands may be varnished. To treat a common iron nickel alloy a bath of perchloric acid and acetic acid may be used.

Abstract: 360,413. Electric clocks. ROSAT, C., Boudry, NeuchÔtel, MOSER, 0. J., 16, Beundenfeldstrasse, Berne, and REYMOND, P., Colombier, near NeuchÔtel, both in Switzerland. July 31, 1930, No. 23112. Convention date, Aug. 12, 1929. [Class 139.] Synchronizing.-Clockwork mechanism is provided with an electric hand-setting device which is so controlled by a continuously energized electromagnet that normally the device is inoperative, but is brought into operation by a momentary deenergization of the magnet. The clock is electrically driven from a circuit, e.g. a. lighting main, which also constantly energizes a magnet a so that its armature b latches a pin l on a bell crank k pivoted at i. The other end k<1> of crank k coacts with a cam h rotated once in twenty-four hours from the minute shaft d. Rigid with the minute hand is an arm w with pin w<1> coacting with a fork v on an arm t which is pivoted at s and rotated counterclockwise by a weight u. Co-operating with a pin r on arm t is a hook o pivoted at n to crank k and having a pin p which is pressed upwards by a spring q on crank k. To synchronize the clock, say at midnight, the circuit is opened by a push button switch, magnet a is de-energized, pin l is released, and crank k is rocked clockwise by spring m so that hook o pulls pin r and fork v to the right, whereby this fork engages pin w<1> and sets the minute hand to correct position. On further rotation of crank k, a foot o<1> on hook o meets a stop z so that hook o is rocked counterclockwise, pin r is released and arm t returns to the left. Subsequently crank k is rocked counterclockwise by cam h to relatch pin l. To prevent the device acting for accidental current interruptions a locking' disc. h<1>, spring- pressed axially towards cam hand. having a slit h<2>, is used. At the correct period the end of k<1>, k is allowed by cam h to pass down slit h<2>. Subsequently a bevel h<3> or disc h<1> allows the end of k to wipe past.

Abstract: 1,205,754. Automatic control systems for oscillation generators. SMITHS INDUSTRIES Ltd. 1 Sept., 1967 [9 Sept., 1966], No. 23562/70. Heading H3A. A circuit for generating electrical oscillations comprises two oscillators of different frequencies and means to derive a pulse of width less than that of the period of the oscillator of higher frequency from each or selected oscillations of the other oscillator, the higher frequency oscillations and the pulses being fed to inputs of an AND gate so that the output of the AND gate is a function of the relative phase of the higher and lower frequency oscillations, said output acting to alter the frequency of the lower frequency oscillator to maintain the relative phase constant. In the illustrated circuit, for use in an electronic clock, pulses are generated by a monostable circuit 10, comprising transistors 27, 28, 29 and receiving the output from the lower frequency oscillator 3 and pass via a differentiating circuit 11 and amplifier 12 to the base of a transistor 35. The latter is in series, in an AND gate 13, with a transistor 34 to the base of which is applied the output of the higher frequency oscillator 1. The output pulses of the circuit 13 are of a width dependent upon the phase difference between the signals from the oscillators 1, 3 and are passed via an integrator 14 to the monostable circuit 10 which is triggered when the magnitude of the signal from the oscillator 3 exceeds that from the integrator 14. The output of the circuit 10 also passes to the oscillator 3 to vary its frequency.
