Patent EP-0214734-A3 (EP)
Title: Method and apparatus for making sulphuric acid
IPC: C01B17/80
Filed: 1986-07-23
Abstract: In a system using the double absorption process for sulphuric acid manufacture, a single acid circulation system and a single cooler are employed. Acid from the exit of the air drying tower and final absorber tower are mixed in a common reservoir, while acid from intermediate absorber tower is discharged to a separate reservoir. Acid from the common reservoir is split between the intermediate and final absorber towers and product line. Acid from the separate reservoir is cooled and split between the drying tower and intermediate absorber tower. The circulation arrangement reduces the cooling to one relatively high temperature location and simplifies acid strength and level control. Only half of the bulk of the circulating acid has to be cooled and the effect of seasonal fluctuating temperatures in the drying tower is minimized.

Title: Photoelectrical position measurement device
IPC: G05D25/02
Filed: 1987-12-19
Abstract: The invention relates to an interferometric position measurement device in which the standard is a defraction grating (G1). Defracted component beams (+m1, -m1) are fed by means of input coupling grids (+HG1, -HG1), which have different grid constants, via optical waveguides (+LWL1, -LWL1) into a coupler (TBJ1), and are caused to interfere there. The interfering component beams are fed from the outputs of the optical waveguides (+LWL1, LWL1, -LWL1) to detectors (+D1, D1, -D1) which convert them into mutually phase-shifted electrical signals. The shift of the defraction grating (G1) is a measure of the change in position to be measured of machine components which can be displaced relative to one another.

Title: Electric switch system for a power tool
IPC: H01H9/06
Filed: 1988-10-12
Abstract: An electric switch system for a DC motor powered 
power tool, comprising: a moveable block (20) which is 
adapted to be manually displaced between a first 
position and a second position for speed control of the 
motor; a fixed block arranged adjacent to the first 
moveable block; a manual selection lever (41) pivotally 
attached to the fixed block and adapted to be manually 
rotated from a neutral middle position to either side 
for the selection of the rotational direction of the 
motor; a cam structure for permitting the manual 
rotation of the manual selection lever in either 
direction away from the middle neutral position 
only when the moveable block is at the first position and 
keeping the angularly displaced state of the manual 
selection lever when the moveable block is displaced 
away from the first position. Thus, the selection of 
the rotational direction of the motor and the speed 
control of the motor can be accomplished as a 
continuous single operation, and the convenience of the 
power tool is improved. Further, since the composite 
control functions can be incorporated into a highly 
simplified integral unit, the manufacturing cost is 
reduced and the reliability of the system is improved.

Title: System devices and algorithm for the error correction in digital transmissions with "bch" coding/decoding
IPC: H03M13/15
Filed: 1989-02-03
Abstract: For the error correction in digital transmissions using the so 
called "BCH" coding/decoding technics, the received data stream 
is processed by means of a modified version of the algo-rithm of 
BCH correction, represented by the 
iterative equations (1), (2) and (3') 
referred in the present description. The calculation of syndromes 
and of the error locator polynomial requires only multiplications by 
a constant factor or by a bit and addition. Hardware implementation 
is greatly symplified by eliminating the need of a two factor Galois 
field multiplier.

Patent EP-0369236-A3 (EP)
Title: Apparatus and method for providing ignition to a turbine engine
IPC: F02C7/266
Filed: 1989-10-31
Abstract: A unipolar ignition of the invention provides a 
current waveform at the ignitor plug which initially 
rises relatively slowly, followed by a transition to a 
fast rising current which quickly peaks and thereafter 
slowly dissipates. Such a current waveform provides an 
initially hotter and longer lasting spark which does 
not harm the ignitor plug of the system or shorten its 
life expectancy. Neither does the spark create stress 
on the solid state circuitry which delivers the energy 
to the ignitor plug. To provide the foregoing spark 
and current characteristics, an inductor having a 
saturable core is in series with the ignitor plug, and 
it provides an initially high inductance which limits 
the rate of current rise at the plug as energy is 
transferred from an energy storage device to the 
plug. As the current through the inductor increases, 
its core begins to saturate and the effective 
inductance begins to decrease, allowing the current to 
rise more quickly. As energy is transferred to the 
ignitor plug, the increasing saturation, decreasing 
inductance and increasing current complement one 
another, causing the rate of current rise to increase 
quickly to a high value desirable for ignition. 
Related features of the invention provide for easy 
diagnostics of the spark and for timing an ignition 
sequence and providing a repetition rate which aids in 
a successful ignition.

Abstract: In einem Bleiakkumulator, der auch über lange Betriebszeiten hinweg zu hohen 
Stromabgaben in der Kälte (Kaltstart) befähigt ist, wird die negative Elektrode 
mit dem notwendigen Expander im wesentlichen aus einer ligninhaltigen 
Depotsubstanz, vorzugsweise Holzmehl, versorgt, welches jedoch Mischungsbe­
standteil der aktiven Masse der positiven Elektrode ist und dort während der 
Formation und Zyklisierung einem oxidativen Abbau, bei dem lösliche Lignin­
derivate freigesetzt werden, unterliegt. Eine solche Expanderquelle erlaubt es, 
die negative Masse ohne Expanderzusatz herzustellen und insbesondere eine 
Überdosierung, wie sie zwangsläufig sonst zu Anfang der Betriebsdauer vor­
liegt, zu vermeiden. Über Konzentration und Teilchengröße des Holzmehls 
lassen sich die Stärke der Expanderzufuhr zur negativen Elektrode und deren 
Dauer weitgehend moderieren.
