Title: Patching hole in thermoplastic fabric in paper-making machine - by cutting elliptical hole, spot-welding overlapping patch, and pressing while heating ultrasonically
Inventor: BLEHER FRITZ
IPC: B29C73/30
Filed: 1989-07-18
Abstract: Fabrics which contain thermoplastic threads are bonded together by overlapping them where they are softened by ultrasonic heating and are pressed together. The whole area of the overlap is heated at the same time, and the fabrics are pressed together at a pressure which brings them almost into one single plane. The process is particularly intended for use with thermoplastic polyester threads. To repair a hole in the sheet-forming fabric at the wet end of a paper machine the fabric is made taut as in service and is placed on a supporting plate. The hole is then punched out into an elliptical shape with sharp edges, and the plate is replaced with a steel plate. An ultra-sonic welder is centered in position over the hole.A patch is placed over the hole so as to overlap 1-3mm over the edges and the patch is spot welded at 2 or 3 points to fix it. An ultrasonic sonotrode is brought down to heat the overlapping area and to press the area with the patch. For this purpose the sonotrode is a ring which aligns accurately with the area. ADVANTAGE - The process is inteded for use in patching holes in sheet-forming fabrics utilised in paper-making machines, whereby the patched areas virtually avoid producing marks on the paper.

Title: Operating digital filter with input A=D converter - involves programmable filter parameters, changeable by terminal connectable via control point
Inventor: BAUMEISTER JUERGEN K DR ING DR
IPC: H03H17/02
Filed: 1989-07-19
Abstract: The digital filter has an A/D converter at the input side for converting the respective input voltage into a code. The filter parameters are programmable and changeable by a terminal connectable via a control point. Then they are permanently stored in a memory associated with the filter. Prior the parameter storage via a diagnostic software pref. a testing is carried out. A computer is typically used as the terminal. A Z-transformation may be used in the filter for realising a quasi-analog control.  Each new code of the A/D converter may be compared with a stored code, used for the last filtering. It is then valued as a new code and stored as a more recent comparison value, if different from the stored code. ADVANTAGE - Improved access for parameter changing.

Title: Condensing solvent vapours from waste air - by cold washing on progressively reducing scale at reducing temps.
Inventor: CURTIUS FRIEDRICH RICHARD DIPL
IPC: B01D5/00
Filed: 1989-10-09
Abstract: Before discharge into the atmos., gases charged with solvent vapour, e.g. waste air from an empty petrol tank, are purified to meet legal requirements by condensation in a series of stages, using a counterflowing washing liq. petrol cooled in an external system. Max. cooling is applied in the first stage to condense most of the susceptible components. At each successive stage the washing liq. is colder and supplied in decreasing amts. In parallel with the washing stages, the washing liq. is being cooled to the various desired temps. in interconnected heat exchangers, themselves cooled by a separate coolant supply system. A rectification column may divide used washing liq. into light components for removal, and liq. charged with the less volatile components for re-use as wash liq. ADVANTAGE - With reduced total cooling demand, less energy is needed to separate and recover solvent to necessary extent.

Title: Steam iron lifting valve - has two ramps to impart rotation through gross pin on valve stem with easy dismantling for descaling
Inventor: AURIA PEREZ AGUSTIN
IPC: D06F75/18
Filed: 1989-12-23
Abstract: Lifting valve for a steam iron, which controls the flow of water to steam chamber, works with a ramp to impart a screw action on the valve stem through a cross pin and rotate it when the valve button is depressed, leads to a second ramp, each ramp being semicircular. The cross pin rides on first ramp from below and second ramp from above. A ratchet point to hold the cross pin is at a point at both ramps, running to each other, to give rotation through the cross pin either into a closing or opening setting. A cross strap, above the cross pin (and parallel to it) is fitted to the valve stem to cover the first ramp from above. Ratchet points are fitted to the under side of the first ramp. The start section of the first ramp lines slightly lower than the start section of the second ramp. The gap between the start sections of the two ramps, through their different height levels, forms a slit opening so that the cross pin can be passed below the ramp. ADVANTAGE - The valve assembly can be removed easily for descaling and cleaning.

Patent DE-4021294-A1 (DE)
Inventor: BAUERSCHMIDT WERNER DIPL ING
IPC: H04B1/50
Filed: 1990-07-04
Abstract: 2.1 Multiple conversion superhet receives, that is to say receivers with multiple frequency conversion, have been known for a long time and are used in preference in radio telephony devices. The radio-frequency carrier oscillation of the transmit oscillator is in most cases supplied to a first receive mixer. Due to the dual utilisation of the transmit oscillator, the intermediate-frequency signal also contains, in addition to the modulation of the received signal, modulation signal components originating from the transmit device. To suppress these components, a compensating device arranged between transmit device and multiple conversion superhet receive device which exhibits an amplifier and a phase-shifting element is in most cases used. 
<??>2.2 The suppression of the modulation signal components originating from the transmit device can be improved by the compensating device containing a frequency control circuit with a voltage-controlled oscillator, the nominal frequency of which corresponds to the sum or to the difference of the first and second intermediate frequency and which is connected to the second receive mixer.
