Title: Auxiliary equipment for photocopier printing plate scanning - enables print density to be automatically controlled for individual items of range of input documents during copying
Inventor: FOERSTER KARL-HEINZ DR ING
IPC: B41F33/14
Filed: 1989-11-06
Abstract: The density of the printed output is uniformly related to the surface area and characteristrics of the individual documents which make up its workload.  Previously registered equipments are capable of integrating the total area for the purpose of  illumination control but cannot discriminate between the individual items which together form the composite workload. The method described employs a system of rectangular coordinates as the basis for the  necessary computation using analogue/digital techniques for data storage and recall with processing by standard modules.  User pre-selection is allowed for via keyboard input and illumination control thus correlated to specific documents on an item by item  basis. USE/ADVANTAGE - Enables improved quality of output where multiple input is required.

Title: Scissors type hydraulic car lift - achieves low drive-on height by using auxiliary cylinder to wedge scissors mechanism open at start of lift
Inventor: NUSSBAUM HANS
IPC: B66F7/08
Filed: 1989-12-30
Abstract: The car lift has two tracks (1), each supported by two crossed links with a central pivot pin (5). The crossed links are pinned to the floor and track at one end and movable on rollers at the other end. A double-acting hydraulic cylinder (10) acts as the main drive to open the scissors linkage and raise the lift. At the bottom position of the lift the upwards force component exerted by the main drive cylinder is small. The specific feature of the invention is an auxiliary cylinder (12) which, acting in parallel with cylinder (10), pulls rollers (11) in the manner of a wedge between the surfaces (2a) and (3a) of the crossed links, thus exerting a powerful lifting effort from the closed position. The auxiliary drive is self-sustaining, so that descent of the load can be closely controlled. USE/ADVANTAGE - Low drive-on height. Does not require special preparation of floor.

Patent DE-4006234-A1 (DE)
Inventor: GOETZELMANN WILHELM DR ING
IPC: C02F1/32
Filed: 1990-02-28
Abstract: A process is described in which hydrogen peroxide is added to the liquid and in which the liquid is then passed through at least one reactor, in which reactor the liquid is subjected to a short-wave electromagnetic radiation. To ensure a sufficient excess of hydrogen peroxide, a first part stream is removed from the treated liquid after leaving the reactor, which is merged with a second part stream containing a solution of reagent which can be reduced by the hydrogen peroxide. The end point potential of the mixture obtained by reaction of the hydrogen peroxide with the substance contained in the reagent solution is used to control the amount of hydrogen peroxide to be added to the untreated liquid.

Patent DE-4032649-A1 (DE)
Title: Dosimeter with pulse count memory - uses digital display multiplex frequency as single time base for all measurement ranges
Inventor: MASSAG CHRISTOPH
IPC: G01T1/17
Filed: 1990-10-15
Abstract: In a dosimeter with a radiation dosage (pulse count) memory, the measurement time is adjusted so that the pulse count corresponds to the dosage without taking account of the decimal point in the digital display. Switching to a more sensitive measurement range (e.g. 1/10 or 1/100) is effected merely by a corresponding extension of the measurement time, the zero effect being accounted for automatically within the dosimeter by initially suppressing a temp.-independent measurement range-dependent number of pulses prior to starting counting in the digital display counter. The need for a separate time base is eliminated when the backplane (or multiplex) frequency of the digital display is used as the time base for all ranges, thus allowing use of a single potentiometer or trimmer for calibrating or characterising all the measuring ranges. All pulses registered by the detector are added and stored and the dosage over a long time period can be determined from the pulse count and the time base frequency. A data transmission unit (e.g. plug) can transmit the time base and the summed pulse count of the memory to a processing unit and/or processing is carried out within the dosimeter. The data transmission may also be used for dosimeter identification. ADVANTAGE - The dosimeter automatically takes account of the zero effect, only requires a single time base and is capable of continuous operation for several years.
Patent DE-4036274-A1 (DE)
Inventor: DURAND DAVID
IPC: H01B1/22
Filed: 1990-11-14
Abstract: An electrically conductive cement which when used to bond electrically conductive mating surfaces provides substantially stable conductivity characteristics under high humidity conditions; comprised of a carrier that provides a volumetric shrinkage of more than about 6.8% (vol.) and a conductive filler including agglomerates, particles, powders, flakes, coated nickel particles, and coated glass spheres, having size and surface characteristics that maintain stable electrical contact by forming a moisture resistant contact with an electrical component lead. The carrier having a volumetric shrinkage between the uncured and cured states of greater than about 6.8% (vol) appears to effect a compaction of the filler particles causing the particles to be forced into enhanced electrical contact with the surfaces to be connected and to provide a measure of compaction between the particles themselves to enhance particle-to-particle conduction. The shrinkage of the polymeric carrier during curing places the interior particles under compression with sufficient force to urge the particles into engagement with one another as well as to cause the particles to penetrate non-conductive oxides that may be present on a component lead. <IMAGE>

Filed: 1990-12-15
Abstract: The circuit has an A/D converter (3) digitising the output from an analog switch (2) that selects consecutively luminance signal (Y) and colour difference signals (R-Y,B-Y).
