Title: Improvements relating to the recording of sounds
IPC: G11B11/03
Filed: 1923-12-22
Abstract: 214,179. Johnson, F. M., and Faucon, A. April 20, 1923, [Convention date]. Records, blanks for; ribbon and tape records and machines; multiple machines; sound-boxes.- Relates to apparatus for recording sound on a relatively hard surface, such as celluloid, by means of a heated stylus, the surface being temporarily softened by a solvent. According to the invention, two very narrow layers of solvent are deposited upon the surface close to the stylus, one layer being in advance thereof and the other in the rear. The apparatus shown, in which a record is made on a film 1, comprises a sound-receiver 9, having a diaphragm 8 and a stylus 7, the receiver being mounted on a support 16 which also carries vessels 14, 15 containing a solvent. Wicks 10, 11, arranged in tubes leading from the vessels, are disposed close to the stylus, before and behind the same, the latter being heated electrically or otherwise. The flow of liquid through the wicks may be regulated by a valve. The solvent applied by the wick 10 prepares the film for the recording action of the needle, while the function of the moistened wick 11 is to smooth and clean the groove. Different solvents may be applied by the two wicks if desired. Several styli operated by a common diaphragm may be used, to produce a number of record grooves simultaneously, a pair of moistening wicks being provided for each stylus. In this case, the film may be divided by means of rotating knives, whilst the recording is taking place, into a number of separate film strips, each one bearing a record groove. Instead of wicks, wheels, hollow needles, brushes, or the like may be employed.

Filed: 1967-07-14
Abstract: 1,217,149. Charging batteries. JOSEPH LUCAS (INDUSTRIES) Ltd. 19 June, 1968 [14 July, 1967], No. 32553/67. Heading H2H. Battery charging system for a road vehicle includes a warning lamp which is actuated both when the battery voltage is below a first predetermined value and when it is above a second higher predetermined value. Supply lines 11, 12, leading from a generator to the battery, are bridged at two places by voltage dividers 13, 14, 15 and 25, 26, 27. Each divider is connected to a respective Zener diode 16, 28 and an associated transistor 17, 22. On closing the vehicle ignition switch, both Zener diodes are non-conductive and current flows through a resistor 19 and diode 21 to turn on transistor 22 and light the warning lamp 23. When the vehicle engine is started, the voltage rises so that Zener diode 16 breaks down, turning on transistor 17. This turns off transistor 22 and extinguishes the lamp. If the voltage rises excessively, the second Zener diode 28 conducts, turning transistor 22 and the warning lamp 23 on again.

Title: Improvements in and relating to direct current restoration circuits
IPC: H04N5/16
Filed: 1953-11-24
Abstract: 731,656. Television. GENERAL ELECTRIC CO. Nov. 24, 1953 [Nov. 26, 1952], No. 32590/53. Class 40 (3). In a D.C. restoration circuit for a cathode-ray tube arrangement including a tube 26 having an anode 27, control grid' 28, cathode 25, and a cathode impedance, and' comprising an integrating circuit and a detector to the input of which the received wave is applied, and the output of which has a direct current connection to the control grid 28 of tube 26 to restore the D.C. component, a direct current path is provided from the cathode impedance to the input terminals of the correcting network, to apply to the latter a fluctuating voltage proportional to the fluctuation of voltage across the cathode impedance in a direction such that the restoration network output contains a component that compensates for the fluctuations of voltage in the tube caused by the cathode impedance. In the arrangement shown in Fig. 2 the incoming signal after detection by valve 15 and amplification in valve 19 is applied over a load resistor 23 and through a condenser 24 to the cathode 25. The grid bias of tube 26 is provided by resistances 50, 51, and 52 with an adjustable tap 55. A restoring arrangement, consisting of an integrating network 31 and 32 and a detector valve 34, is connected across resistors 51 and 52 and its output passes over a smoothing network to grid 28. The fluctuations in grid bias due to changes of current flow in the tube 26 would normally disturb the restoration effect. As, however, a proportion of this fluctuation is superimposed on the input of the correcting circuit compensation is effected. In the circuit shown in Fig. 3 the correcting network is placed across the whole of cathode impedance 60. The adjustment of the grid bias is effected by a rectifier circuit 70 supplied by pulses from the horizontal sweep circuit.

Title: Process for the manufacture of low-molecular weight dialkyl sulphoxides
IPC: C07C317/00
Filed: 1960-09-23
Abstract: Dialkyl sulphoxides in which the alkyl radicals contain 1 to 4 carbon atoms are prepared by liquid-phase oxidation of the corresponding dialkyl sulphides by oxygen or gas mixtures containing free oxygen in the presence of nitrogen oxides as oxygen-carriers, the gases involved in the reaction being so finely dispersed and mixed in the liquid phase by agitation of the reaction mixture that a dispersed quantity of gas of at least 7% by volume, based on the liquid, is established in the liquid phase.  The process may be carried out continuously or discontinuously and in one or more stages.  The dispersion of the gases in the liquid phase is accomplished by vigorous agitation with a high-speed agitator, or by ultra-sonic waves.  In the continuous process a mixture of dialkyl sulphide, dialkyl sulphoxide and oxygen-carrier is agitated whilst passing in a mixture of dialkyl sulphide and oxygen-containing gas and simultaneously removing a corresponding amount of liquid from the reaction mixture, the oxygen-carrier being replenished as necessary. The unreacted dialkyl sulphide and the oxygen-carrier may be recirculated.  In Examples: (1)-(3) and (5) dimethyl sulphide is oxidised to dimethyl sulphoxide; (4) diethyl sulphide is oxidised to diethyl sulphoxide.  Other specified reagents are dipropyl, dibutyl, methylethyl, methylpropyl, ethylpropyl, ethylbutyl and propylbutyl sulphides.  Specification 737,575 is referred to.
