Patent EP-0053418-A2 (EP)
Inventor: GRUPPING ARNOLD WILLEM JOSEPHU
IPC: E21F15/00
Filed: 1981-11-20
Abstract: A method for the underground gasification of coal or browncoal in an inclined coal layer, in which two boreholes are drilled into said layer, and are continued downwards in a converging manner with the inclination of said layer. After initiating the combustion of the coal, the cavity formed thereby is filled by a granular filler material suspended in a carrier substance supplied through a borehole, the cavity then being filled with the exception of a narrow channel in which the combustion of a substantially straight coal front can be continued. When using a carrier liquid, the latter is pressed out by means of a pressurised gas before restarting the combustion. If water is flowing in from the surrounding formations, it can be kept away from the filler near said channel by barometric action by means of a tube ex- tanding downwards in a borehole to the desired water level, the pressure being maintained during combustion, e.g. by including suitable throttle means in the gas discharge.

Abstract: An electrochemical cell having two electrodes of opposite polarity cooperating with an electrolyte solution to produce an electrical potential therebetween during normal operation, configured to minimize explosions upon forced discharge or charging by locating at least a portion of one electrode in close proximity to the other electrode such that a low impedance path is created between the two electrode surfaces whereby the quantity of externally imposed current flowing through the main body of the cell is minimized. In a preferred embodiment, portions of the two electrodes have contiguous surfaces spaced from each other by a porous separator material (24) with the surfaces chosen to allow plating dendritic growth from one electrode to the other at potential differences below that at which electrolysis occurs.

Abstract: A method of preparing a mixture consists in successive performing of: atomization of fuel in a stream of exhaust gases, introduction during suction or an exchange of the load of an incombustible fuel-combustion mixture to a separate storage space, compression - in a positive-displacement manner without mixing - of the mixture with the air inflowing to the storage space from the working space of the engine, forcing through of the compressed mixture into the combustion chamber before the top dead center of the piston completing the compression strike, and in production of a combustible mixture by mixing with air compressed in the combustion chamber. 
     A piston engine of internal combustion of the mixture produced by the said method utilizes the configuration of a piston (5) and a head (17) separating in the range of the top dead center a combustion chamber (1) and a forcing-through chamber (2). Additionally, it has a storage space (3) connected periodically by a periodically cutting-off mechanism with an exhaust gases passage comprising a device (7) atomizing the fuel. The storage space (3) is shaped so that it connects in a through manner the forcing-through chamber (2) and the combustion chamber (1) separated in the range of the top dead center of the piston. The storage space (3) can be situated in a head (17) or in the head of the piston (5), whereas the cut-off mechanism can be a pressure-controlled non-return valve (6) or directly the piston (5) performing the function of a slotted timing gear in co-operation with passages of the cylinder (16). 
     The solution can be applied in four-stroke and two-stroke spark-ignition and compression ignition engines.

Abstract: A method and apparatus for sensing the present position of a movable machine element in a position control system when a position control loop in the system is placed in the open state. In the position control system, error storage means (107b) computes and stores an error between a command value produced by a control unit (102), and an amount of movement sensed by a position sensor provided on a motor shaft or on the movable machine element, and a speed control circuit controls the motor in accordance with the error from the error storage means (1 07b). The method of sensing present position includes steps of reading and storing as a steady deviation the error from said error storage means (1 07b) immediately before the position control loop is switched from the closed to the open state, reading the error in the error storage means (1 07b) when the position control loop is in the open state, updating the content of a present position register (202) on the basis of an arithmetic difference obtained by subtracting the steady deviation from the read error, and revising the content of the error storage means (107b) by the arithmetic difference.

Abstract: In order to increase the detection sensitivity of measurements for locating a fuel rod that has become defective, the present invention proposes to provide the upper end plugs for fuel rods in liquid cooled nuclear reactors with an enhanced tendency to deposit washouts, entrained by coolant, of fission products from rod defects through the configuration or nature of the shape and/or the surface of said plugs. As special measures to increase the deposits, changes in shape are proposed which cause separation vortices, thus e.g. separation edges (11, 12) or concave regions (13), or else the roughening or coating of parts (14) on the fuel rod plugs. In particular, it is proposed to coat with a getter for specific isotopes. Roughening, coating or flattening of the plug tips can also be carried out subsequently on already existing fuel rods. <IMAGE>

Abstract: An engine timing apparatus comprises an ultrasonic transducer 8 which directs a pulsed ultrasonic beam into a cylinder and converts the reflected ultrasonic signals into electrical signals. A sample/hold circuit 67 samples this signal at a time after each pulse when signal reflected by a piston ring passing through the beam are expected. A microcomputer 65 detects changes in the level of the sampled signal caused by the piston rings as the crankshaft rotates, and receives signals from a transducer 71 indicating the crankshaft position to allow top dead centre position to be found. The microcomputer receives signals from a microphone 51 directed at a fuel injector indicative of the onset of ignition and calculates the timing angle of the engine. The apparatus also calculates engine speed and detects piston slap.

By adjusting the torque transmitting force of the friction clutch, one of the two torques is selectively applied to the separating rollers depending on whether or not the sheets are held between the feeding rollers and separating rollers.
