Title: Improvements in or relating to nail varnish compositions
IPC: C09D101/18
Filed: 1938-07-07
Abstract: 516,788. Cellulose nitrate compositions ; synthetic resin compositions. DU PONT DE NEMOURS & CO., E. I. July 7, 1938, No. 20206. Convention date, July 8, 1937.

Patent GB-1535975-A (GB)
Title: Magnetohydrodynamic generator
IPC: H02K44/10
Filed: 1976-05-17
Abstract: The electrode (14) has an elongated first electrode element (22) which is arranged inside a second electrode element (26), forming an annular gas (24) through which gas flows. An arc is struck between said electrode elements in order to generate a plasma. The electrode (14) is arranged parallel to the direction of the magnetic flux, which results in the arc rotating about the first electrode element (22). In order to increase the power and/or to suppress erosion, the electrode material, current density and gas pressure are selected such that a cathode spot occurs, the first electrode (22) having a uniform cross-section along its operating section. This longitudinal movement is superimposed on the rotation and can be further intensified in various ways. In this way, the arc of an electrode can move much more intensively within a cavity which is located along one or more openings in the electrode. This results in the ionised gas filling the entire cavity and being forced into the generator duct, where it acts as a gas electrode. At the same time, erosion is in this way suppressed so that it is possible to operate with higher current densities than in the past. The high temperature of the electrode prevents carbon slag being deposited on the electrode opening so that a path which is electrically conductive to a large extent remains open for the load current. <IMAGE>

Abstract: 1,145,319. Automatic frequency control. systems. MARCONI CO. Ltd. 22 Feb., 1968 [2 May, 1967], No. 20339/67. Heading H3A. An oscillator 4 is synchronized to a harmonic of a reference frequency by direct comparison at the oscillator frequency in a phase-discriminator 31 and by comparison at a divided frequency in a frequency comparator 10. The reference frequency is derived from a source 1 by a frequency divider 2 and feeds a harmonic generator 9 and a harmonic selector 91 which is ganged to a tuning control of the oscillator 4 to provide an equal frequency as the second input to discriminator 31. The oscillator 4 feeds a variable divider 7 which provides one input to the comparator 10, the other input being derived from the divider 2 with a further divider 22 being provided if necessary. The control signals derived from units 10 and 31 may be combined by a potentiometer 11<SP>1</SP> and fed to a reactance 5<SP>1</SP> controlling the frequency of oscillator 4. Alternatively, Fig. 2 (not shown), the two control signals may control separate reactances in the oscillator.

Abstract: 322,779. Bacon, J. N. July 13, 1928. Stationary-vessel wet-separating and washing apparatus. - Graphite is obtained from mineral of poor quality by treatment in a washing apparatus A to which water is also added through a control valve B until the outlet pipe C is just covered. The valve B is then regulated to give a steady flow of water at the outlet pipe C. The cover of the washer is replaced and the paddles with which it is provided are set in rotation at the rate of 45 revolutions per minute. The graphite and lighter materials are washed into the discharge tank E and the settling tanks E - - J and when thev have been all washed away, which takes about half an hour, the valve B is closed and the tailings are discharged into the tank E by opening a door D. The mineral is then removed from the settling tanks F - - J for further treatment.

Title: Desulfurization of hydrocarbon oils
IPC: C10C3/00
Filed: 1961-06-06
Abstract: <PICT:0913730/III/1> Sulphur, and also metal and nitrogen, impurities are removed from hydrocarbon streams, especially petroleum fractions such as heavy fuel oil and residuum, by contacting the stream with a molten caesium hydroxide containing 5-30% by weight of water, based on the total reagent, at a temperature of 300 DEG -700 DEG F.  The reagent may also include one or more of molten sodium, potassium or barium hydroxides, and the caesium hydroxide preferably comprises from 1 to 20 mol. per cent of the reagent.  The spent reagent may be regenerated by steam hydrolysis and recycled.  In the Figure, a hydrocarbon feed, for example a 950 DEG F. + kuwait residuum, passes via line 1 into purifying zone 2, where it is contacted with caesium hydroxide reagent entering via line 3.  The mixture enters zone 5 where it is separated into a caesium hydroxide phase and a residuum phase.  To facilitate the separation a distillate fraction such as gasoline, heavy naphtha, kerosene, heating oil or other fraction boiling below 700 DEG -800 DEG F. may be introduced via line 16.  The hydrocarbon phase passes through line 15, washed with water from line 17, and separated in zone 18, from which the product is recovered via line 19.  The hydroxide is regenerated in zone 8.  Heavy metal impurities may be removed before entering zone 8.  Specification 913,729 is referred to.
