Title: Impedance measurement on microphone connected to telephony card
Inventor: SEDDICK PETER DIPL ING
IPC: H04M1/247
Filed: 1996-05-13
Abstract: The handset (HA) with acoustic coupling (AK) between its earphone (HK) and microphone (MK) is connected to the personal computer card (PK) in which the microphone feed (MS) is also connected to an A/D convertor (ADW), and the line (L1) from the earphone to a D/A convertor (DAW). To measure the impedance, the controller (ST) varies the polarity in synchronism with a clock signal.  The impedance-dependent signal is digitised and evaluated by the controller, which interprets a high result as denoting an electret microphone for which the correct polarity is then worked out.

Patent DE-19633526-A1 (DE)
Title: Remote protection/branch protection for power transmission line shorting
Inventor: JURISCH ANDREAS DR
IPC: G01R31/02
Filed: 1996-08-09
Abstract: A method for the generation of an error identification signal which serves to identify a short-circuit through an arc occurring on/in a multiphase power transmission line. A measured variable proportional to the short-circuit voltage is sampled and the sampled value then stored. The error identifying signal is generated through an evaluation of the sampled value. The power transmission line is monitored in single-phase or two-phase clear of earth with occurrence of a short-circuit, and a fundamental oscillation (Us (t)) contained in the short-circuit voltage is determined regarding its amplitude (As) and phase (phi), from the sampled values (U (k)). A rectangular signal (Ur (t)) is then formed, and the fundamental (Us (t)) is compared with the sampled values to obtain a similarity value (Vs) giving signal similarity. The rectangular signal is then compared with the sampled values to obtain a further similarity value (Vr), and the error identification signal is given when the similarity between the rectangular signal and the sampled values is greater than the similarity between the fundamental (Us (t)) and the sampled values.
Patent DE-19637161-A1 (DE)
Inventor: HOSAGASI SEVKI DIPL ING
IPC: H02P6/16
Filed: 1996-09-12
Abstract: The invention relates to a control method for brushless electromotors, especially direct current motors comprising a stator with a rotary field winding composed of at least three coil pairs, a rotor with permanent magnets the number of pole pairs of which corresponds to the number of coil pairs, and an incremental transmitter located on the drive shaft of the rotor transmitting a multiplicity of electrical impulses dependent upon the rotation of the rotor and presenting a synchronous mark in relation to the shaft, wherein determination of the position of the rotor is carried out during an orientation phase, after which the electromotor is driven in stepwise mode to attain the synchronous mark and only when this mark is reached the electromotor is switched into normal operation mode.

Title: Brake disk for motor, with ABS, cycle disk brake system
Inventor: HEUBNER WILHELM DIPL ING
IPC: F16D69/00
Filed: 1996-09-14
Abstract: The brake disk (1) has alternating protrusions (4) and recesses (5) in rings about the rotation axis (6) made of the ferromagnetic material of the disk and forming a sensor or pulse ring at a radial distance from the active braking friction region (3) for detecting the revolution rate.

The heat flow between this region and the active braking friction regions is reduced by openings (8) and/or thinning of the material with a uniform peripheral distribution.
Patent DE-19638355-A1 (DE)
Title: Cooking sensing method for hotplate
Inventor: ROTHENBERGER GERHARD DIPL ING
IPC: H05B3/74
Filed: 1996-09-19
Abstract: The method has a hotplate (1) fitted with a sensor (10) e.g. a microphone, to monitor the sound generated by the bubbles. By analysing (11) the relative amplitudes of the noise at different frequencies, the control system can differentiate between simmering and boiling. The bubbles generated at the bottom of the cooking vessel generate different frequencies of noise to those bursting at the surface of the liquid when boiling. A feedback control turns down the heating setting at the onset of boiling. The control system (12) monitors low frequency noise below 1000 Hz and high frequency noise above 1000 Hz. Filter circuits separate the two levels of noise. When the amplitude of the low frequency noise increases while that of the high frequency noise decreases, boiling starts and the control system reduces the heating. For the converse, indicating going off the boil, the heating is increased.

Title: Pretzel biscuit-forming assembly has rotating gantry with two grab arms
Inventor: SCHEITENBERGER HUBERT
IPC: A21C3/08
Filed: 1997-05-20
Abstract: Assembly winds pre-cut lengths of dough into the traditional Pretzel biscuit form prior to baking. The assembly consists of an overhead gantry (2) which rotates through 360  deg , to which two grab-arms (31a, 31b) are fixed. Each arm (31a, 31b) has two lifting grips (6) which hold the ends of a length of dough.  A motor (7) drives a mechanical gear with four sections on the gantry (2).  The gear sections power the various functions such as raising and lowering the dough-ends (52) before the sequence of movements shaping the unbaked Pretzel.  Each part of the gear incorporates a mechanical e.g. cam control which dictates the operating sequence and periods of arm motion and rest.  The grip arms lift and wind the ends (52) of the dough.  The Pretzel is then formed by a single full rotation of the gantry unit (2).  The dough ends (52) are then pressed against the Pretzel centre section (1) and the grips (6) returned to their initial position.  The sequence is repeated as part of a continuous operation.

IPC: A61G5/10
Filed: 1997-06-06
Abstract: The wheelchair (10) can be fitted out to enlarge the bearing surface between chair and ground as well as prevent sinking into place for easier movement. This is provided by expansions to the standard chair wheels (1) and their grip rings (2). This bearing surface expansion can also be obtained by replacing standard by wheels or rollers with larger bearing surface. In a variant, the expansion of the bearing surface is achieved by connecting the driving wheels and steering wheels by chains, straps or vee-belts. Additional wheels or rollers should be in their own frame which in turn can be used to transport objects. The additional frame can also be pulled or pushed by a helper. This enlarged surface system is suitable for firm, uneven or weak ground.
