Title: Circuit for capacitive measurement transducer - contains flip=flop, filter, null point regulator, amplifier and thermistors for temp. compensation
Inventor: ERLER KLAUS DR ING
IPC: G01L9/12
Filed: 1990-10-27
Abstract: The circuit for a capacitive measurement transducer contains a flip-flop, a low-pass filter, a null point regulator and an amplifier. Measurement capacitors (C1,C2) operating on the differential capacitor principle are connected to the flip-flop (1) via leads of minimal length. The filter (2) converts a pulse-width modulated signal from the flip-flop into a d.c. voltage which it feeds to the amplifier (3). The null point regulator (5) also enables null point temp. conpensation in conjunction with a thermistor (6). The amplifier also operates with a thermistor (8) to achieve temp. compensation. USE/ADVANTAGE - For electrical conversion of measurement parameters detected by capacitive transducers, esp. differential capacitor arrangements, e.g. for measuring differential pressure or air speed. Linear characteristic over wide range is achieved at low cost.

Title: Domestic tea or coffee making machine - has mechanical time-switch using ratchet memory wheel and pawl operated by bimetallic memory wire
Inventor: DAX MICHAEL DIPL ING
IPC: A47J31/52
Filed: 1990-12-21
Abstract: The hot drink machine has a hot plate (12) above a through flow heater (14) with a temp. regulator (16). Below this is a long wire (26) made of bimetallic strip held in tension by lugs (20, 24) and a spring (28). As the wire expands or contracts, by virtue of the heater, it controls the movement of a pivoted lever arm (38). The upper end of this (44) acts as a pawl on the ratchet-like projection (36) of the wheel (32), both projections and upper arm having triangular cross-section when seen from above. One of the wheel's projections (54) has an extension which, in the off-position, touches a microswitch (56). Once the wheel is manually rotated counterclockwise, the microswitch is released and the appts. is turned on. The angle through which the wheel is rotated is a measure of the required time elapse. During this period, the heater is continually switched in and out by the regulator as its temperature rises and falls and the alternate lengthening and contracting of the wire ratchets the wheel clockwise until the microswitch is closed again. ADVANTAGE - Simple and robust automatic switching off after certain, pref. settable, time.

Patent DE-4133679-A1 (DE)
Inventor: MUELLER WERNER DIPL PHYS
IPC: F02D41/24
Filed: 1991-10-11
Abstract: The description relates to a process with the aid of which the inaccuracies in the individual segments occurring during the manufacture of a pick-up wheel can be electronically corrected. To this end, in the recognised decelaration running, when there are therefore no rotation speed fluctuations, the duration of the spacing between two segment flanks of the same polarity is measured and the values thus obtained are stored. These values are a measure of the different segment lengths and are taken into account in the calculations made during normal internal combustion engine running to determine the exact rotation speed. The correction or adaptation permits highly accurate rotation speed determination which can be used to calculate precisely the uneven running and hence to recognise misfiring.

Title: Drying machine to continuously handle delicate knitted folded fabric - comprises stillage in lap form feeding fabric to lattice through guide- and controllable lifting rollers w.r.t. height of pile, avoiding shape distortion
Inventor: PETERSOHN GERHARD
IPC: D06B23/00
Filed: 1992-09-07
Abstract: The fabric is to be fed into the machine on carrying lattice through guide and lifting rollers. The lifting motion is controllable, and set w.r.t. the height of the pile of folded fabric, while holding at the pref. width. Pref. the fabric is brought to the machine on a type of stillage in lap form and is fed upwards in the direction on to the lattice which is held rigidly on the stand. As the fabric is taken from the stillage, the guide rollers are held at the correct distance to start unfolding without increasing the lift, by moving the frame by a helical spindle which is driven by the motor, through the advance gear. This enables the frame to be set in a pref. position in the direction, to the specified extent. The motor may be driven stepwise, or with a steady advance. The drive is positioned at each side of the frame. Alternatively the movement may be by pneumatics. In the frame there are guide rollers, which have appts. provided to ensure the fabric is held at the correct width. This has opto-electic appts. in the controllers to ensure the fabric travels along the middle of the rollers regardless of width. Also there are rotating brushes to hold the fabric to the guide roller. Further guide rollers on the inside of the stand ensure the fabric takes the shortest path on to the lattice. The lifting motion of the frame may be automatically controlled by a sensor and the lifting gear. USE - Feeding material into a drying machine avoids stretching out of shape due to handling inappropriately.
