Patent FI-965299-A (FI)
Inventor: AHMAVAARA KALLE
IPC: H04W24/04
Filed: 1996-12-31
Abstract: The invention relates to a method for a duplex telecommunication connection in radio connections based on a frame-structured interactive communication and a radio system where the frame-structured interactive communication is performed in the radio connections. The invention provides a means for improving the use of channel resources in the implementation of the interactive telecommunication connection by providing a FDD connection with one or more TDD dimensions. The general approach of the invention is that a full-duplex frequency band is time-duplexed into two or more sub-bands in which interactive communication takes place substantially independently. Transmissions in different transmission directions in each sub-band occur at different times, but a simultaneous transmission can take occur in two different sub-bands in different transmission directions. It is an advantage of the invention in interactive communication that the message is received entirely in one transmission direction before it needs to be responded in another transmission direction in a particular sub-band. On the other hand, the frequency band is utilized effectively for communication because transmission can be performed simultaneously in different sub-bands in the reverse transmission directions.

Title: Improvements relating to electrical amplifiers
Inventor: FIELDEN JOHN ERNEST
IPC: H03F3/40
Filed: 1954-01-14
Abstract: 765,683. Valve amplifying circuits. FIELDEN ELECTRONICS, Ltd., [formerly FIELDEN (ELECTRONICS), Ltd.]. April 7, 1955 [Jan. 14, 1954], No. 1099/54. Class 40(6) A direct-current amplifier comprises a leaky-grid detector-oscillator coupled with an anode-bend detector. The leaky-grid detector-oscillator V1 is of the cathode-tap type and the anode-bend detector V2 is connected across the oscillator coil L1. Each detector has a pair of series resistors R1, 3 and R2, 4 respectively, in its anode circuit with the ratio R1:R3=R2:R4. The common points in each pair, A, B respectively, are bridged by a pair of input terminals E2 in series with a moving-coil meter movement M the pointer a of which forms, with a fixed electrode b a variable capacitor. This capacitor forms, with the series grid capacitor C1 a variable tap across the oscillator circuit, since the anode of the valve V1 is earthed for oscillator frequency via a capacitor C2. A pair of output terminals E2' are connected to the valve anodes. The circuit is adjusted so that in the absence of any input at the terminals E1 the anode potentials of the valves are equal and the current through the meter M zero. Any change in oscillator amplitude then causes the anode currents in the two valves to change in opposite directions; the resulting current through the meter M alters the grid tapping point of the valve V1 in such a sense as to restore the amplitude of oscillation to normal. The insertion of a potential at the terminals E1 likewise tends to upset the balance and the circuit responds so as to reduce the current in the meter M to zero. An equal and opposite potential then exists across the points A, B, and a potential amplified in the ratio (R3+R1):R1 across the ouput terminals E2.

Title: Improvements in or relating to the automatic voltage control of dynamo-electric generators
IPC: H02P7/34
Filed: 1938-01-13
Abstract: 509,318. Exciting dynamos; control of D.C. motors. LANCASHIRE DYNAMO & CRYPTO, Ltd., and STANSFIELD, W. Jan. 13, 1938, No. 1210. [Class 35] . [Also in Group XXXVII] In a constant-speed separately-excited directcurrent generator, especially for Ward-Leonard systems, in which the voltage is regulatable over a wide range by varying the excitation, the voltage is stabilized at low values by connecting the armature with the separately excited field so that the voltage of the armature - tends to reduce the excitation. In Fig. 2, the field 11 of the generator 14 is supplied through a reversing switch 20 from an exciter 12 in series with a resistance 13, the armature being also connected to the field through a resistance 15 and switch 19. Part or all of the resistance 13 can be short-circuited by switches 21 and 21a, and the switch 19 opened at high speeds, but for low speeds either of the switches 21 and 21a is opened to reduce the voltage across the field 11 and the switch 19 is closed. A buffer resistance 22 which may consist of the armature of a separately excited motor fitted with a fly-wheel may be connected across the field 11 or across the field and part of the resistance 13. In a modification, a resistance of low value connected in parallel with the resistance 13 is open-circuited for low speeds. Fig. 4 shows a regulating system providing continuous variation of the speed of the motor 17 by variation of the current in the field winding 11 of the generator 14, maximum speed being obtained with the movable tapping 25 in the uppermost position wherein the voltage applied to the field winding 11 from the potentiometer resistance 24 is a maximum and there is no connection between the field winding 11 and the armature of the generator 14. Downward movement of the tapping 25 reduces the voltage across the field winding 11 and effects increasing stabilization of the generator voltage by reducing the resistance 15a. To obtain zero output of the generator in spite of residual magnetism, a resistance 26 is included between the field winding 11 and the lower end of the resistance 24 so that when the tapping 25 is at the lowest point on the resistance 24, the resistance 26 is in shunt with the field winding 11 ; the voltage drop in the resistance 26 due to the voltage of the generator 14 is opposite in direction to that normally applied to the field winding 11, whereby the residual magnetism of the field is cancelled. In a modification (Fig. 5, not shown) the regulator is adapted to reverse the output of the generator.

Title: Process for obtaining metals from sulphide ores
IPC: C22B5/00
Filed: 1929-10-23
Abstract: In obtaining metals from sulphide ores, the ore is heated in the presence of hydrocarbon material with exclusion or air and the residue is concentrated on percussion tables, by gravitational or magnetic treatment, or by leaching.  The ores, preferably finely granulated, are treated at a temperature of about 500 DEG  C., i.e. slightly above normal low temperature distillation, but the temperature may be raised to above 600 DEG  C. and kept below the normal reduction temperature to liberate wholly or mainly the metals from the compounds in the ore.  The heating may be carried out in the presence of a catalyst such as sulphate of iron, gypsum or h matite, with or without lime.  Gaseous hydrocarbons, such as acetylene, water-gas, coal-gas, and mineral or other oils may be used in place of coal as the reducing agent.  The gas recovered during the heat treatment is utilized to heat the furnace.  The concentrates may be further treated in the anodic chambers of an electrolytic bath. Containers for the concentrate to be treated are formed by dividing the bath by porous plates and suspending the cathodes in the containers.  Electrolytic copper may be obtained directly from the concentrate.  If metal first obtained is impure, the various metals may be separated in succession by electrolysis.  In an example, 100 parts of copper pyrites reduced to grains of about 1 mm. mixed with 10 parts by weight of coal and 1 part by weight of sulphate of iron, and distilled at 600 DEG -700 DEG  C., yields after concentration grains of metallic iron and large granules of copper.

[Class 8 (i)] [Also in Groups XXIX and XXXIV] A compressor, such as is described in Specification 517,371, is actuated by epicyclic gearing comprising an internally toothed cage a driven by the motor and meshing with planetary pinions b carried by the end flange e<SP>1</SP> of a brake drum e, the pinions driving a sun wheel d<SP>1</SP> fixed to the compressor shaft when the drum e is stopped by a coil brake f surrounding the drum and having a loose end adapted to be pressed against the drum by a roller h pressed upwards by a spring i<SP>2</SP> against a crosshead h<SP>1</SP> carrying the roller. The crosshead is supported by pegs h<SP>2</SP> extending from a piston which is depressed by admission of air to its interior through valves p, q during a certain range of pressures. Thus as the delivery pressure rises, air passing through passages g<SP>5</SP> first depresses diaphragm p<SP>2</SP> and allows valve p to be closed by its spring, some air still leaks past the valve through a leaky passage g' and a port g<SP>8</SP> to the interior of the brake piston without affecting operation ; as the pressure rises higher the diaphragm q<SP>2</SP> is depressed allowing the valve q to fall and the air to pass this valve and depress the brake piston, stopping the compressor.

Filed: 1931-01-19
Abstract: 361,185. Protective cut-out systems. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Jan. 19, 1931, No. 1772. Convention date, Feb. 25, 1930. [Class 38 (v).] When overload relays protecting a network operate the voltage of the network, and tho sensitiveness of the relavs are reduced. When one or more overload relays 8, 9, 10 operates, an auxiliary relay 11 is energized by a battery 12, to connect a resistance 7 in the field circuit of the exciter 5 of the generator 4, and also to connect resistances 13, 14, 15 in parallel with the overload relays. The sensitiveness of the relays is thus reduced, and when the current is reduced sufficiently by the reduction of voltage, the relays again open. The original sensitiveness of the relays is restored, and the resistance 7 again short-circuited. The relay carrying the greatest excess current then operates, and the cycle begins afresh. A momentary inclusion and exclusion of the resistance 7 is thus obtained, and the generator current fluctuates between fixed limits regulated by the adjustment of the overload relays. The sensitiveness of the overload relays is reduced to such an extent as to cause them to open their contacts at the same current value at which their contacts close, or vice versa. The relay 11 may be energized by the exciter voltage to prevent excessive de-excitation. The reduction in voltage may be produced by the insertion of chokes in the supply lines, or by varying the exciter field turns.
