Patent FI-952310-A (FI)
Inventor: MONTONEN MAUNO
IPC: F16H3/72
Filed: 1995-05-12
Abstract: The invention is related to a rotational speed converter comprising shafts (1, 2) with bevelled gears fixed thereon, separate bevelled gears (3, 4) which cooperate with said gears fixed onto said shafts and are mounted on a separate shaft (5), a planetary gear (6) connected to said separate shaft, and at least one braking gear (7) acting on said planetary gear. In speed converter, according to the invention, are fluid flow channels (9, 10) connected to the braking gear (7), whereby the fluid volume surrounding said channels is filled with a hydraulic fluid that is arranged to pass through the gaps formed between teeth of the braking gear (7) and the planetary gear (6) from the suction side to the pressure side, and that the converter additionally incorporates a control valve for adjusting the fluid flow from the pressure side (9) to the suction side (10), whereby the hydraulic system thus formed makes it possible to control the fluid pressure on the pressure side thus permitting braking of the braking gear and the rotational speed of the planetary gear in a desired ratio, whereby a stepless conversion ratio from zero to 1:1 between the speeds of the input shaft (1) and output shaft (2) is attained.

Title: Improvements in or relating to method and apparatus for controlling the flow of heated media
IPC: F23N5/12
Filed: 1947-01-14
Abstract: 702,131. Coating with metals; granulating metals &c. METAL CARBIDES CORPORATION. Jan. 14, 1947 [Jan. 15, 1946], No. 1227/47. Class 82 (2) [Also in Groups XI, XII, XXII and XL(a)] The flow of heated media especially a flame or arc is controlled by creating a unidirectional electrostatic field between the arc which forms one electrode and an adjacent object to be heated, using normally 3000-5000 volts. Thus a positively charged arc 18 is deflected to a negatively charged plate 19 (see Group XI). Specification 702,187 is referred to. The Specification as open to inspection under Sect. 91 comprises also the separation of vapours or particles of metals or other materials from hot gases by passing them from a hopper 27 adjacent the positively charged arc 26 and the negatively charged plate 28, on which the particles are collected. An oxidizing or non- oxidizing atmosphere is used; and in the latter case, pure metal globules are collected on the plate 28, which may be heated, so that the molten metal, e.g. copper vaporized from comminuted copper ore in an atmosphere of hydrogen, may be run off and collected. The size of the precipitated metal or other particles may be controlled. Thus metal carbides may be deposited on steel and sintered by the arc, and tungsten carbide may be precipitated on a tool. A metal, e.g. tungsten, may be vaporized and condensed on the plate 28. An alternating potential may be used or the polarities may be reversed. Soot may be reclaimed from burning materials. This subject-matter does not appear in the Specification as accepted.

Patent GB-573499-A (GB)
Title: Improvements in or relating to high pressure chemical reactions
IPC: B01J8/00
Filed: 1942-02-04
Abstract: Gases are caused to react under extremely high pressures by absorbing at least one gas in a liquid absorbent at between -30 DEG  and 200 DEG  F. under a pressure between 2 and 1,000 atm., increasing the pressure on the resultant liquor leaving the absorber and containing the absorbed gas or gases to a pressure of from about 400 and preferably 2000 atm. to a pressure approaching the desired final pressure (2000 to 12,000 atm.), and then heating to a temperature above that in the absorption zone but below 800 DEG  F. and so that the pressure reaches the desired final pressure.  The gas may then be freed from the absorbent, e.g. by gravitational separation, the freed gas having the pressure and temperature under which the desired reaction is to be maintained. Alternatively, the reaction may be carried out in presence of the absorbent held at the desired pressure.  The absorbent may be gas oil, lubricating oils, tars, whale oils, gasoline, kerosene, water, mineral acids or alcohols. Catalysts such as butyl or ethyl chloride, and boron trifluoride may be used.  The process may be used in reactions of methane with oxygen, carbon monoxide or dioxide to produce aldehydes or alcohols, in methane and ethane polymerization and alkylation reactions, reactions of methane with tar or asphalt, ethane with isobutane, and propylene and butenes with water or acids.  An example is given of the methanization of cracking coil tar, and of the treatment of methane with isobutene.

Filed: 1921-01-10
Abstract: Synthetic tanning-agents are prepared from tars or tar oils by introducing acid groups without isolating the components from the tars or oils, converting the acids into their metal salts, and then coupling these salts by appropriate elements or radicals. According to an example, a tar oil is sulphonated by concentrated sulphuric acid, the product is made alkaline with caustic soda, sodium carbonate, or lime, and then condensed with formaldehyde solution.

Patent GB-157860-A (GB)
Title: Improvements in the manufacture of zinc white
IPC: C01G9/08
Filed: 1921-01-10
Abstract: Zinc sulphide is prepared by a wet process from granular zinc carbonate or zinc oxide obtained therefrom by treatment with caustic soda or potash.  The granular zinc carbonate is obtained by passing carbon dioxide into a solution of a zinc salt, in the presence of magnesia or magnesium carbonate.  Excess of the zinc oxide or carbonate is suspended in a dilute solution of a zinc salt or in a dilute solution of an acid such as hydrochloric acid; in the latter case a portion of the oxide or carbonate is dissolved.  On passing sulphuretted hydrogen, zinc sulphide is precipitated, and the acid which is simultaneously liberated prevents the formation of oxysulphides or polysulphides.  The Specification as open to inspection under Sect. 91 (3) (a) also contains the following subject-matter:-Magnesia and hydrochloric acid are recovered from the magnesium chloride resulting when the zinc carbonate is precipitated from zinc chloride solution.  The basic carbonate is precipitated by the addition of magnesia to the magnesium chloride and is calcined after filtration.  Zinc oxide may be obtained by calcination of the granular zinc carbonate; zinc sulphide may also be prepared by precipitation from a solution of the granular zinc carbonate or oxide in acetic acid or in dilute mineral acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 557,350. Speed governors. ENGLISH ELECTRIC CO., Ltd., PAULIN, G. H., HORNER, F. H., and BERMAN, L. Feb. 11, 1942, No. 1786. [Class 135] A speed governor, particularly adapted for controlling the fuel supply to a fuel injection type internal combustion engine driving an electric generator supplying an electric traction motor in which the engine regulator is actuated by a servomotor controlled by a centrifugal governor has the governor loading spring adjusted manually and by the movement of the servomotor. In the form shown in the Figure a lever 14 coupled to the engine fuel pump is actuated by a piston 11 under the control of an auxiliary piston valve 5 working in a rotating ported tubular member 1. A disc 2 formed on the member 5 carries weighted arms 3 bearing on a disc 4 secured to the piston valve. The governor loading spring 7 is arranged between an abutment bearing through a ball-bearing 6 on the disc 2 and a movable abutment 8 slidably guided in the casing. The abutment 8 is pivoted to the mid-point of a lever, one end of which is coupled by a link 13 with the piston 11 while the other end bears on a movable fulcrum 15. This fulcrum comprises a pair of rollers carried by a bell-crank lever 16 connected by a link to an arm 18 on a shaft 18a connected to a driver's handle or to a power device under the driver's control. A further arm on the shaft 18a works between a pair of adjustable stops to limit the movement of the shaft 18a. As the shaft 18a is rotated the fulcrum moves to adjust the initial tension of the spring and also to vary the leverage of the lever 9. In a modification the lever 16 is mounted on a slidably mounted pivot adjustable in a direction at right angles to the spring axis.
