Title: Process for the disposal of combustible wastes
Inventor: GRISAR ALEXANDER
IPC: C04B7/43
Filed: 1984-03-27
Abstract: The invention relates to a process for the disposal of combustible wastes during the production of cement clinker by preheating and partial calcining of the cement raw meal in a preheater, combustion in a tubular rotary kiln and subsequent air cooling of the clinker, the waste being separately burnt and the flue gas resulting in this process giving off heat to the cement raw meal. In the process according to the invention, hot exhaust air from the clinker cooling is fed to the combustion of the waste and, during the combustion, flue gas with a temperature of 1000 to 1400 DEG C is thereby generated and used for calcining the cement raw meal. The slag of the waste combustion is taken off separately.

Title: Spacing/adjusting wood screw connector
Inventor: LUTZ ERICH
IPC: F16B5/02
Filed: 1984-09-27
Abstract: Application: the use of the spacing/adjusting wood screw connector is intended mainly for mounting wooden substructures (batten structures for wooden-strip floors, Rigips, wall and ceiling claddings, facade claddings, etc.) where irregularities in the mounting base have to be compensated for. Function: the spacing/adjusting wood screw connector is screwed fixedly, through the mounting part (4), on the fastening base (5) until the head of the screw is countersunk. Once the cone anchor (2) has penetrated into the wood of the mounting part (4), then both parts have been fixedly combined. By turning the screw in the opposite direction, the mounting part (4) can be adjusted away from the mounting base (5) into the desired spacing position. The axial strength of the cone anchor (2) permits all the conventional methods for mounting claddings, including mounting by means of nails. <IMAGE>

Patent DE-3502046-A1 (DE)
Title: Function generator for generating curved segments
Inventor: DATHE JUERGEN DR
IPC: G06F17/17
Filed: 1985-01-23
Abstract: The invention relates to a circuit arrangement for the digital generation of a quantized electrical analog signal of any curved shape and initial phase, extending monotonically between two successive interpolation points of an amplitude/time function, particularly as reference variable for electro-servohydraulic control loops or electrodynamic vibration generators. The aim is to relieve digital computers included in the circuit of time-consuming interpolation calculations and output operations and to implement a computer-independent function generator for periodic signals. The object to be achieved consists in creating a generator which operates autonomously on a computer bus or control processor. The essence of the invention consists in the generation of the signal segment by interpolation between two interpolation points in 2<n> steps by means of recursive subtraction of the 2<nth> part of the difference between the subsequent and the current interpolation point by means of a hard-wired computing circuit. Frequency control is effected in a known manner by means of a synthesis generator. The interpolation process is operated by the write pulses for the register preceding a digital/analog converter, which is extended by n bits in the direction of the lower significances compared with the DAC processing word length.

Title: Means for purifying, and keeping pure, contaminated water, in particular ground water for drinking purposes
Inventor: BECKER OTTO ALFRED DR
IPC: C02F5/02
Filed: 1985-03-16
Abstract: The invention relates to means for purifying, and keeping pure, contaminated water, in particular ground water for drinking purposes. For this purpose the invention provides two solutions. According to the first solution, the contaminated regions are separated off from the inflowing pure water so that this is forced to flow away or flow on at the side of the region of contaminated water without contact with this. As a result, the contamination regions are locally isolated. According to the 2nd solution, filters are connected intermediately transversely to the direction of flow in the contaminated regions. The contaminations are retained by the filters. Only pure water flows on. <IMAGE>

Patent DE-3525641-A1 (DE)
Title: Method and device for the contactless crushing of concrements in the body of living beings
Inventor: EISENMENGER WOLFGANG PROF DR
IPC: A61B17/22
Filed: 1985-07-18
Abstract: In a method or in a device for the contactless crushing of concrements in the body of living beings a source generates shock waves which are focussed on the concrement and destroy it. In order to avoid tissue damage in the treated body, the profile of the pressure amplitudes of the shock waves to be focussed is lowered locally toward the outside. Another supplementary possibility of avoiding tissue damage resides in the fact that the pressure amplitudes of the shock waves are first of all quickly increased and then reduced again. In a device for carrying out the method a metallic membrane is excited by a conductor arrangement exposed to current pulses to produce impulses, which are fed as shock waves to the concrement to be destroyed via corresponding coupling bodies and focussing devices. In order to reduce the profile of the pressure amplitudes in the edge region of the shock waves, for example, the winding density of the conductor arrangement is reduced towards the edge region or the wire thickness of the individual windings of the conductor arrangement is increased towards the edge region. This method can be applied generally to all systems for the generation and focussing of shock waves.

Title: Locking device
Inventor: SPERBER ALFRED
IPC: E05B27/08
Filed: 1985-09-27
Abstract: The invention relates to a locking device consisting of a key and lock. Arranged within the lock is a shaft (1) which carries at least two diametrically opposite cams (4, 5) and on one shaft end (2) of which the key can be slipped fixedly in terms of rotation. The lock body (6) has, in the region of the cams (4, 5), wells (7, 8), in which are arranged blocking elements (9, 10) which are slidably displaceable in the released state and which are under the effect of springs (40). The blocking elements (9, 10) are equipped with a plurality of blocking pins (11) which, being under the effect of compression springs (12), engage into bores (13) of the lock body (6), and thereby block the blocking elements (9, 10), so that a rotation of the shaft (1) is prevented. Longitudinally stepped intermediate or additional pins (27) are arranged in the bores (13). Release takes place by means of tappets of the key which are of adjustable effective length and which push back the additional pins (27) and therefore the blocking pins (11). Furthermore, each blocking pin (11) is assigned a holding pin (37) of equal length which is loaded by the spring (38). The holding pins (37) block the blocking elements (9, 10) in their position pushed outwards. <IMAGE>

Patent DE-3539259-A1 (DE)
Title: Arrangement for the rapid positioning of a stepping motor
Inventor: KUCHENBECKER MANFRED DR ING
IPC: H02P8/22
Filed: 1985-11-06
Abstract: The invention relates to a position control loop for dynamically demanding positioning tasks, preferably using permanent-magnet stepping motors with a cyclic-absolute position transmitter (which is coupled to the rotor shaft) by means of which it is possible to multiply the resolution capability by dividing the structural stepping angle of the stepping motor by large divisor values. The position transmitter is connected on the input side to a first two-phase system. The actual position of the motor is reflected in the phase angle of the output voltage from said position transmitter.   Furthermore, there is a second two-phase system whose phase angle is shifted with respect to the first two-phase system in accordance with the required rotation angle. The commutation signals for the motor windings are formed by comparing the phase of the transmitter output voltage with the first two-phase system, and the difference between the desired value and actual value is formed, in the form of a digital signal with a continuously variable duty ratio, by phase comparison with the second two-phase system. This digital signal is supplied directly, or after modification by a regulator, as a current or voltage control signal to the driver circuit of the stepping motor. This arrangement can be designed as an integrated circuit and can be used in printing and writing technology as well as in automation and robot technology. <IMAGE>

Title: Writing device for a recording system
Inventor: FISCHER GERHARD
IPC: G01D15/16
Filed: 1985-11-13
Abstract: In a writing device for a recording system by means of which, in particular, measurement quantities are recorded on a continuous writing surface, a plastic line provided with a capillary, the end of which is used as writing point, is carried from an ink container to the writing surface. The plastic line is supported slightly displaceably in its longitudinal axis by a guide tube in the pivoted lever. The free end with the writing point is attached to a guide cradle which is supported displaceably on a linear guide. The guide cradle is supported pivotably at the linear guide and is heavier on the side pointing towards the free end of the ink line than on the other side. Due to this design, effects of force of the relatively stiff plastic line on the contact pressure of the writing point can be compensated for.
Patent DE-3546373-A1 (DE)
Title: Hydrodynamic drive by means of a two-stroke diesel engine with opposed free pistons and a hydraulic pump
Inventor: WAGNER ALBERT
IPC: F03B13/00
Filed: 1985-12-31
Abstract: In this drive, the reciprocating motion of the free pistons of the diesel engine 1 is converted into rotary motion by means of the pressurised water delivered by the hydraulic pump 3, using a free-jet back-pressure turbine 100. While being of simple design, without a crank mechanism and cylinder head, exhibiting complete balancing of masses in each cylinder, smooth running and low frictional and heat losses, this drive has the advantages over the known four-stroke diesel engines that the power-to-weight ratio and specific fuel consumption are lower because the free-jet back-pressure turbine is lighter - with high delivery pressures and high speeds of rotation - and has a higher efficiency than the crank mechanism. The upstream pressure, required for the hydraulic pump, in the return line 12 is maintained by means of compressed air in the closed housing of the free-jet back-pressure turbine. The simple and robust free-jet back-pressure turbine comprises a housing with two or four nozzles and a rotor with a shaft. With constant nozzles, the turbine speed, which is dependent on the delivery rate and loading, is controlled by controlling the injection quantity of the diesel engine. <IMAGE>
