Title: Method for a computer network game "rally" and an optical-mechanical generator of two random numbers for carrying out said method
Inventor: DOVGAN VLADIMIR V
IPC: G02B27/00
Filed: 2003-03-06
Abstract: The method finds application in playing on personal computer (5) by a user connected by means of a network (2) to a server (3). It forms displacing speed of displaceable images. Two random numbers are introduced in a software. A means for affecting the speed of the images by users is embodied in such a way that it provides only two states of control signals affecting the speed. Each said state of the means is compared with one of the two random numbers. The means state coinciding with the random number, the speed of the displaceable images (6) is modified. When one of the states of the means coincides with the random number, the speed of movement of the image of the moving object (6). The state not being coincided with the random number, the initial speed is preserved. A race is over when the predetermined position screen (4) is obtained or when a predetermined time is finished. The inventive game is carried out in several stages, which comprise at least one race. The winner of each stage is provided with a classification rating, the game being carried out by players who are equally rated. The mechanical generator (8) comprises a revolving drum (9) in which light absorbing (10) and light reflecting (11) balls are arranged. A beam of a source light is directed towards the area where said balls (10, 11) are disposed. Photoreceiver (13) is arranged in such a way that it receives a beam reflected by the balls.

Title: Process for non-ferrous metal ores flotation
Inventor: PANAYOTOV VLADKO
IPC: B03D1/00
Filed: 2005-06-02
Abstract: The method can be applied for the flotation of copper, copper-pyrites, copper-molybdenum, copper-zinc, lead and lead-zinc ores. It guarantees higher degree of the mineral extraction without the use of depressors and activators. The process includes the use of anolyte and catholyte produced during electrochemical treatment. Before the flotation the ore is ground in a medium of anolyte produced in a diaphragm electrolyzer at current density from 2 to 30 mA/cm2 and voltage from 4 to 36 V for 1 to 5 min. Immediately after grinding, to the pulp produced from the ground material and anolyte, the catholyte produced in the diaphragm electrolyzer is added and flotation is performed wherein summation and foam-producing reagents are used.

Patent GB-1050018-A (GB)
IPC: H02K47/24
Abstract: 1,050,018. Frequency changers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 28, 1965 [April 29, 1964; Nov. 6, 1964], Nos. 17746/64 and 45379/64. Heading H2A. In a self-motoring frequency converter in which the stator and rotor carry ordinary induction motor windings as well as the frequency converting windings, the two sets of windings being of different pole-numbers in the usual way, the secondary winding is a poleamplitude modulation winding acting as a closed circuit for one pole-number (for motoring) and as an output winding at the modified frequency for the other pole-number. Generally, the primary windings are on the stator and are mains-energized to provide the two pole numbers, while the secondary windings are on the rotor. In the form shown in Fig. 1 (not shown) the stator carries two separate windings of different pole numbers, while the rotor carries a single, parallel-star winding providing one pole-number in the series (mutually shorted) operation, and the other pole-number in parallel operation. In a modification (Fig. 2, not shown) the primary (stator) winding is also of pole-amplitude modulation type and energized simultaneously for both pole-numbers, i.e. in series and parallel simultaneously. This is achieved by energizing each phase winding from a centre-tapped transformer winding, and also feeding a centre-tap on each phase winding itself. Winding layouts are described.

The engine described comprises first rotor member comprising a compressor disc 16, and turbine disc 18, carrying blades 35 and 42 respectively which blades extend parallel to the axis of the engine, and a second rotor member 26 comprising a compressor disc 27 and a turbine disc 28 carrying blades 34 and 41 which extend parallel to the axis of the engine and co-operate with the blades 35 and 42 all respectively. Air flows through the inlet to the compressor and fuel is burned in the air in the space 36 which constitutes a combustion section, the gases discharging radially outwardly through the turbine 41, 42. A ring-shaped deflector member 47 is provided adjacent the outlet of the turbine, the deflector member being supported from a ring member 45 by means of struts 46, the ring member 45 and so the deflector being movable axially by means of rams 43 between the downstream position shown in which the turbine exhaust gases discharge radially outwardly through an annular opening 48 in the engine casing 10, and an upstream position in which the curved inner surface of the deflector acts to deflect the turbine exhaust gases in an axial direction through an annular space defined between an outer wall 25 and an inner wall 23. The rotary member 26 is spaced from the casing 10 to define an annular passage in which are disposed fan blades 49 mounted on the rotary member 26, the engine thus being a gas-turbine ducted fantype engine.

Abstract: 1,050,524. Hydraulic pit props. COAL INDUSTRY (PATENTS) Ltd. Sept. 6, 1963 [June 8, 1962], No. 22363/62. Heading E1E. An hydraulic pit prop having at least three telescopic sections 12, 15, 16 is provided with a breather hole 27, and bleed holes 26, the latter limiting the extension of the prop. Co-operating abutments 24, 25 of the sections may be replaced by pegs projecting from the cylinders 15, 16. Again, the abutment 24 could be omitted and the abutment 25 or a sleeve attachment to the cylinder 16 engage the underside of the seal 22 to effect extension of the section.

Abstract: 1,052,087. Gravity - separation apparatus. INGENIORSFIRMAN FLIESBERG A.B. and F. JUELL. June 23, 1964 [June 24, 1963], No. 25925/64. Heading B1D. A fibre suspension, such as white water from paper-making machines, is supplied through an air absorption vessel 4 and a valve device 5 to an inlet chamber 2, where air dissolved in the suspension is released, the fibres and flocks being thereby raised to form a layer 6 removed by scrapers 9 to a chamber 3. Clear water is discharged at 11. The upper edge of a partition wall 13 separating chamber 2 from a basin 1 is shaped so as to extend forwardly in the direction of flow of suspension. Such shaping is found to provide more rapid thickening of the floated fibres.

Abstract: 1,054,954. Converting. ALLMANNA SVENSKA ELEKTRISKA A.B. May 14, 1964 [June 7, 1963], No. 20061/64. Heading H2F. The low voltage ignition of a by-pass valve 1, which is connected in parallel with a main converter valve, is improved by inerting a device 32 in the voltage divider as shown to boost the voltage in the lower cathode region of the valve. The device shown in Fig. 1 is a varistor so that when the low igniting voltage is first applied its resistance is high and most of the voltage appears between the cathode and the nearest electrode. If however, the by-pass valve is to be ignited at a high voltage. in order to block the main valve, the resistance of the device is low and the high voltage is evenly distributed across the valve. The device may also be a Zener diode or a source of D.C. to boost the voltage in the divider (Fig. 2, not shown), this having the advantage that the capacitors in the divider are charged before the igniting voltage is applied.

Abstract: 1,080,234. Inflatable shoots. FRANKENSTEIN GROUP Ltd. July 13, 1965 [Sept. 4, 1964], No. 36307/64. Headings B7A and B7J. A collapsible escape shoot for an aircraft, which shoot may be used as a life raft, comprises an inflatable floor A, and semi-elliptical sidewalls D bounded by arched inflatable tubes E which are hinged at their ends to the floor A and releasably connected together at their crests F. The sidewalls automatically extend laterally upon release of the connection at F so that the tubes E become part of the gunwale of a life raft whose floor is represented by the floor A and sidewalls D of the original shoot. The floor A comprises inflatable tubes C located between rubberized fabric sheets B. Fabric gussets which may be inflatable may be extended between adjacent ends of the arched tubes E to form a continuous gunwale when used as a life raft. In a further embodiment the whole of the sidewalls D are inflatable.
