Title: Fireclay and calcine are produced in a rotary kiln coupled to an alternative fuel kiln
IPC: F27B7/36
Filed: 1997-11-07
Abstract: In a fireclay and calcine production process, an alternative fuel unit is coupled with the production unit so that the active firing zone is utilized as the post-combustion zone for the waste gases from the alternative fuel unit. In a fireclay and calcine production process as described above, alternative fuel unit (second rotary kiln) hot gases are fed at 850-950 deg C into the top of the is coupled with the production unit (first rotary kiln) and are heated by the installed natural gas burners to above 1200 deg C for more than 2 sec. to achieve the requisite gas temperature for the firing operation.
Patent DE-19750835-A1 (DE)
Inventor: KLEFENZ FRANK DR
IPC: G06F17/00
Filed: 1997-11-17
Abstract: The monotone and constant trajectories which are searched for are made coincidental with the storable code signal shapes, said shapes also being reconfigurable, in a translation invariant manner. According to the inventive method and device, trajectories are thus detected with a higher measuring precision in shorter durations. According to the inventive method, the determination of running time differentials also occurs for the other applications in an exemplary manner by detecting the code signal shapes in the upper C1a or lower signal detection unit C1b and by additional processing of the information in the downward connected multicoincidence unit C2, whereby a shift invariant parallel multi template matching is carried out in the detection units C1a and C1b. Trajectories are correlated during said multi template matching in a parallel manner. A set of running time differentials in the form of an output vector D is output to the series connected multicoincidence unit C2. The method is suitable for exact determination of trajectories and, in addition, can thus be used for locating signal sources in the area, for measuring movement trajectories, and for measuring velocity and acceleration.

Title: IC engine/electric generator drive for cars
Inventor: KLAUE HERMANN DR ING
IPC: F02B71/04
Filed: 1998-01-28
Abstract: The generator drive has a rectangular working chamber (11,12) with inlet and outlet slots (2,3) located opposite one another, aligned at an angle to the working chamber heads. A piston (4) has inclined (41,42) faces corresponding to the roof-shaped working chamber heads (51,52). Fresh gas (6) flowing in upper or lower dead points meet in the middle with the exhaust gas (7) flowing to the outlet. An IC engine/electric generator drive for cars has in the rectangular working chamber, preferably designed with a quadratic cross-section, inlet and outlet slots located opposite one another, aligned at an angle to the working chamber heads of the IC engine. The piston has inclined faces corresponding to the roof-shaped working chamber heads which conduct the fresh gas flowing in the upper or lower dead point of the piston to the upper or lower part of the working chamber. The fresh gas flowing in the upper or lower dead point meets in the middle with the exhaust gas flowing to the outlet. In the working chamber, an assimilation takes place between the surfaces of fresh and exhaust gases resulting in removal of nitrogen. The intensive contact between fresh and exhaust gas is guaranteed by the rectangular design of the engine's working chamber in a way such that is not possible with a cylinder shape for the working chamber.

Title: Liquid-dispensing instrument for e.g. cream, mayonnaise, mustard, sauce etc.
Inventor: BUNYAN GLENN WALTER
IPC: B05C5/00
Filed: 1998-06-17
Abstract: The instrument is particularly for viscous liquid such as cream, mayonnaise, mustard, sauce etc., having a piston (4) working in a cylinder (2) between two chambers. The first (24) of the latter discharges the liquid, while the second (26) accommodates liquid to be delivered to the first one, the two being connected via a non-return valve (3). As the piston travels to-and-fro, the volume of the first chamber is reduced, so as to discharge the liquid, while that of the second is increased, to allow liquid delivery to it, while movement in the opposite direction reduces the volume of the second chamber, transferring the contents to the first one.

Abstract: Two stereo pictures are used, of which that for the right eye has to be mirror-reversed. On the insides of an angle device with an angle function of 110 degrees friction occurs on static surfaces which are exchangeable for different sorts of paper. Despite adhesion of the pictures their manual displacement is made possible in arbitrary directions and they can be seen on a mirror reflecting to the right and located on the insides of the angle device. When the left side of the angle device is observed, with the outer edge of the mirror touched by the point of the nose, with the right eye the reflected right picture can be seen and at the same time the left picture with the left eye, whilst the left picture is moved by hand to adjust to the individual eye distance.

Title: Rotating machines torque measurement method esp. for electric motors
Inventor: GRIEPENTROG GERD DR
IPC: G01L3/12
Filed: 1998-10-19
Abstract: A method for measuring the torque of rotating machines in which response signals are generated axially displaced at, at least, two points of a rotating shaft by means of a light-beam on the rotating shaft, and in which the resulting azimuthal displacement over the rotational movement is used to evaluate the signals.  A continuous light beam is used for signal generation, and the torsion-dependent deflection of the light beam is geometrically amplified before the evaluation process, and from this the precise azimuthal displacement is determined. The torsion- dependant deflection of the light beam specifically forms the response signals after geometrical amplification, and the time difference of corresponding response signals is ascertained as the azimuthal displacement.

Patent DE-19904106-A1 (DE)
Inventor: BSCHORR OSKAR
IPC: G10K7/00
Filed: 1999-02-02
Abstract: The aim of the invention is to produce a sound generator for eliminating interference by means of sound absorption and for reproducing signals, speech and music. The sound is preferably generated by means of micro- and nanomechanical air pumps (12) whose output flow is controlled by the actuator (16) according to the required sound signal and exits via a sound channel (11); the complementary channel (11') acting on a closed buffer volume (15). As with conventional loudspeaker enclosures, the function of the buffer volume (15) is to make an acoustic monopole radiator out of the ineffective dipole of the sound channel (11) and the channel (11'). In the case of air pumps (12) with high pressure ratios, the necessary buffer volume is correspondingly small. The sound-generating volume flow is measured in the sound channel (11) by means of a micromechanical flowmeter (18) and can be readjusted according to a comparison of the desired value and the actual value. Finally, a bore (19) with a high flow resistance balances out air pressure fluctuations and drift errors in the buffer volume (15).

IPC: H03K5/08
Filed: 1999-02-08
Abstract: The invention relates to a comparator circuit comprising a comparator which is provided with an operating point T1. A supervisory circuit suppresses undesired signal bouncing at the output. Said bouncing is produced by interferences of the input signal. The supervisory circuit ensures that the circuit output is locked from being switched back to another logical level after switching until the input signal has reached a second threshold value T2 that is higher than the operating point T1.
