Title: Method and device for controlling the pressure in a deaerator arranged in the feed-water line of a steam power station
Inventor: MATSUSHIMA TOKUNORI
IPC: F01K7/38
Filed: 1981-02-13
Abstract: A method for controlling the pressure in a deaerator arranged in the feed-water line of a steam power station, a proportion of the steam or the water being led off from the deaerator to a unit which functions at a lower pressure than the deaerator, for example to the low pressure feed-water preheater, a condenser or the like, in the event of a sudden and rapid drop in the load acting on the steam turbine, by means of which the steam pressure in the deaerator is kept at a lower level than the extraction steam temperature, in order to safeguard the supply of extraction steam to the deaerator at the required volume flow even when the load acting on the turbine is reduced very rapidly. In addition, a device for performing the said method is described, which comprises a discharge line (18), through which a proportion of the steam or water is led off from the deaerator (1) to a unit functioning at lower pressure, for example to the low pressure feed-water preheater (3) or to a condenser (5) when the load acting on the steam turbine is suddenly and rapidly reduced; in addition, a volume flow control valve (17) arranged in the discharge line (18) and a valve adjusting unit (19) for adjusting the degree of opening of the volume flow control valve (17) in accordance with the pressure differential between the extraction steam pressure and the deaerator internal pressure. <IMAGE>
Patent DE-3106542-A1 (DE)
Title: Valve gear of a four-stroke reciprocating piston internal combustion engine
Inventor: KRUEGER HERMANN
IPC: F02B75/02
Filed: 1981-02-21
Abstract: In order to reduce the friction and mechanical stressing in a valve gear of a four-stroke reciprocating piston internal combustion engine with inlet and exhaust valves, which are arranged essentially parallel to the axis of the cylinders assigned to the engine, opened by desmodromic valve gear and closed under the action of valve springs, it is proposed to design the spring force of the valve springs so that in the maximum operating speed range the valve closing acceleration is at least temporarily less than the valve closing acceleration resulting from the cam drop flank. At the same time it may be advantageous to design the valve springs of the valves so that the springs assigned to the inlet valves increase the frictional connection before the maximum operating speed is attained, but the valve springs assigned to the exhaust valves on the other hand eliminate it shortly after the maximum operating speed. In order to prevent damage to the valve stem guide and to the valve discs when the valves collide with the piston heads, at least the exhaust valves may have concentrically projecting stop cams on that side of the valve discs facing the piston, whilst the surfaces of the piston heads coming into contact with these stop cams have an increased impact strength and wear resistance.

Title: Multicylinder reciprocating piston internal combustion engine with a device for shutting off lifting valves
Inventor: BIERLING RUDOLF
IPC: F01L13/00
Filed: 1981-02-24
Abstract: For shutting off cylinders of a multicylinder internal combustion engine, a swivel member for the relevant lifting valves on the camshaft is accommodated so that it is displaceable according to the cam lift and by means of an adjusting lever, swivel mounted on the camshaft, and a driver, capable of swivelling about the axis of rotation of the camshaft into two limit positions so that in the one limit position an effective connection is made between the cam and the respective lifting valve by way of an intermediate plate of the swivel member, whilst in the second limit position this effective connection is cancelled and the lifting valve thereby switched off. Because the outer surface of the swivel member runs in a radius and interacts with the tappet, switching on and off is stepless and thereby wear-free.

Title: Method and shaft furnace for burning lumpy articles to be burned such as limestone, dolomite, magnesite or the like and use of the shaft furnace
Inventor: BERTSCH ERICH
IPC: F27B1/00
Filed: 1981-05-14
Abstract: The articles introduced into the shaft furnace (1) at the top sink successively through a preheating zone (V), a combustion zone (B) and a cooling zone (K). Burnable gas (9) is supplied to the combustion zone (B), cooling air (21) to the cooling zone (K). The part (20) of the at least partially consumed burnable gases which sinks downwards with the burnt articles from the combustion zone (B) passes together with the rising cooling air (22) into a cylindrical shaft insert (18). Injectors (10) suck the gas mixture out of the shaft insert (18) and guide it to the combustion zone (B). The injectors (10) are operated with the waste gas of a gas engine (15). As the injectors (10) are supplied with the waste gas of a gas engine (15) as propellant, and not with driving air as previously, the air proportion of the furnace gases is reduced and as a result the thermal efficiency of the furnace is surprisingly increased. <IMAGE>

Title: Device for charging a battery which is located on a vehicle having a linear drive
Inventor: HOLWECK PETER DIPL ING
IPC: H02J7/14
Filed: 1981-06-26
Abstract: In the case of a device for charging a battery which is located on a vehicle having a linear drive, in the case of which a row of linear-generator windings supply a DC power controller via individual bridge rectifiers, the bridge rectifiers are connected in parallel on the output side, a switching transistor is connected between the supply leads to the battery and a diode is inserted in the forward direction in the supply lead to the positive terminal of the battery and to the transistor connection point, the object of the invention is also to make it possible to charge the battery at a low vehicle speed, without additional means for speed measurement. This object is achieved in that two limit-value switches (2, 3) are provided, whose inverted outputs are connected to an AND gate (4) which is connected to the base of the switching transistor (1), the first limit-value switch (2) being supplied with the difference between the charging current (IB) and a desired charging current value (IB'), and the second limit-value switch (3) being supplied with the difference between the transistor current (IK) and a desired transistor current value (IK'). <IMAGE>

Title: Concrete paving stone multi-layer laying method
Inventor: AUMILLER RUDOLF N
IPC: E01C19/52
Filed: 1981-07-20
Abstract: The invention relates to a concrete paving stone multi-layer laying method with a mobile stacker truck and a laying device which carries with it laying units stacked in a number of layers on pallets and always removes the upper layer of interlocking stones, pivots it and sets it down in the sand surface. The laying arm, which is fastened on two struts or support construction on the roof, can be a rigid jib with a sliding piece, a telescopic boom or an articulated boom. The actuation can take place mechanically with oil or air pressure. By means of a rotary device, the jib is intended to reach all positions, being pivotable by 360 DEG . Actuation with levers on or near the driver's stand is expedient. The main advantage of the method is that the existing technology of the stacker truck is supplemented with two struts for receiving the load and crane booms are fastened thereon with laying tongs. Since a number of laying units are transported along at the same time, the lost time to fetch individual laying units, which is the case in many other methods, is eliminated. <IMAGE>

Title: Method for braking a stepping motor
Inventor: GERJETS HEINZ
IPC: G05B19/23
Filed: 1981-11-14
Abstract: A clock transmitter synchronised to the running of the motor of a stepping motor supplies a clock pulse for each motor step, which clock pulse is used to initiate the winding drive pulses for the respectively next motor step. The time interval between the successive clock pulses and the number of clock pulses are determined and stored during the entire acceleration phase. During the braking phase, the stored time intervals are taken from the store in the reverse sequence and the motor windings are driven at these intervals until the stepping motor has moved to the desired position.
