Abstract: The specification describes thermal ink jet (TIJ) processes and device structures produced thereby wherein either heater resistors or heater resistor-diode combinations are constructed vertically upward from a common supporting substrate. A lower or first metal level conductor pattern provides one part of an X-Y matrix multiplex connection to the resistor/diode components, and a second, upper metal level conductor pattern forms the second part of the X-Y matrix multiplex connection. In this manner, the multiplex drive circuitry for the TIJ printhead resistors/diodes may be fabricated (integrated) directly on the thin film resistor (TFR) printhead substrate. Additionally, the second level metal conductors which overlie the resistive heater and diode elements also serve as a barrier shield to ink corrosion and cavitation wear.

Abstract: A method for effecting enzymatic reactions can be carried out using a microporous enzymatic reactor (2) which comprises a porous support (4) having thereon a crosslinked polymeric membrane (8) containing solubilizing groups and having an enzyme attached thereto. In a preferred embodiment, the membrane is composed of polymers prepared from acrylamide or methacrylamide monomers containing active methylene groups, and solubilizing ethylenically unsaturated monomers. The method is carried out by causing a feed stream (6) containing a substrate for the enzyme in a first solvent to flow rapidly and continuously over the surface of the membrane. A product of the enzymatic reaction occurring in the membrane is collected in a product stream (10) containing a second solvent which is immiscible with the first solvent, the product stream being separated from the feed stream by the enzymatic membrane.

Abstract: A frequency synthesizer is provided in which the output is a truly continuous sweep of frequency, not a staircase of spot frequencies. A programmable frequency divider PD is connected to the output of a voltage-controlled oscillator (VCO) to divide the VCO output by a variable integer N. At each VCO output cycle, the integer N is incremented (or decremented). The output of a phase comparator PC, which compares the divider output with a fixed reference frequency, is connected via an integrator (10) to the VCO frequency control input (2). A constant phase error produces a ramp rise of VCO frequency.

Abstract: The present invention is directed to a method of manufacturing a thermoformed, form-retaining article comprising a form-retaining thermoformable substrate and a flexible web coverstock. The method comprises feeding a continuous strip of the flexible web coverstock through a thermoforming line comprising at least a lamination station, a thermoforming station and transport means. Sheets of the substrate are fed into the lamination station and there laminated to said continuous strip of coverstock material. The coverstock is wider than the substrate sheetstock laminated thereto, and thus, it extends laterally beyond the sheetstock, i.e., it has free longitudinal edges. The transport means engages the continuous strip of coverstock material along the free longitudinal edges thereof. The transport means is actuated to advance the continuous strip and, hence, each successive piece of substrate laminated thereto from the lamination station into the thermoforming station. The thermoforming line optionally comprises additional stations, such as ornamentation stations, trim stations, and the like. Additional material may be included in the lamination such as, for example, padding-type materials between the coverstock and the substrate, an additional sheet of coverstock on the opposite side of the substrate sheetstock, and the like.

Abstract: The invention relates to an ignition system, particularly of the static-distribution type, in which a respective ignition coil (C) with a primary winding (5) and a secondary winding (6) is coupled to the spark­ing plug (SP) associated with each cylinder. The system includes a respective switching transistor (T) for each ignition coil (C) and control circuit devices (4, 7 -11) which, in order to generate a spark in a plug (SP), cause a first switching of the corresponding transistor (T) from the shut-off condition to the conducting con­dition to start the flow of current in the primary wind­ing (5) of the associated coil (C), and a second switch­ing to the shut-off condition to stop the flow of cur­rent in the coil (C), causing the striking of the spark. These control circuit devices (4, 7 - 11) are arranged to control the speed of the first switching of the transistor or transistors (T) concerned from time to time, for each ignition, so that the first switching takes place gradually at a speed less than a predeter­mined value. The amplitude of the voltage peak which is applied to the sparking plug (SP) in correspondence with the first switching is thus drastically reduced.

Inventor: BLOTENBERG WILFRIED DR-ING
IPC: F04D27/02
Filed: 1989-02-23
Abstract: In the case of known methods of the type stated the normal control is deliberately restricted in its reaction speed. In order to protect the compressor in the event of large and/or sudden malfunctions a safety control is installed which, when it responds by actuating a switch valve, triggers complete rapid opening of the venting valve under spring force. The disadvantage here is that triggering of the safety control leads to a sharp drop in pressure on the pressure side of the compressor. The new method is intended to avoid this drawback. 
<??>The new method is characterised in that a second control differential (x'), where necessary indicating the need for rapid opening of the venting valve, is calculated from the measured values and/or the first control differential (x) and default reference values and fed to a limit value stage and that, if a default limit value in this limit value stage (54) is exceeded by the second control differential (x'), the said stage emits a rapid opening variable (z) on the output side which is sent to the controller (4) where, by cumulative superimposition, a change in the valve control variable (y) is produced with an increased rate of change causing actuation of the valve in the opening direction. The new method has the advantage that, where necessary, it increases the reaction speed of the control so that in the event of major and/or rapid malfunctions a prompt opening of the venting valve is ensured which furthermore takes place only as far and as prolonged as necessary. 
<??>The new method is suitable for the control of turbocompressors in any sphere of application, in particular for retrofitting to existing controls.
