Title: Method for start-up of an apparatus for the continuous generation of biogas
Inventor: KLEIN MICHAEL
IPC: C12P5/02
Filed: 1988-09-08
Abstract: To generate biogas, organic waste materials in the form of a liquid to pasty mass are anaerobically digested in the absence of air by action of a mixture of bacteria of fermentative, acetogenic and methanogenic strains. Especially during the start-up phase, to avoid overacidifying the organic waste material mixture used, not inconsiderable amounts of additives are required to establish the required pH. According to the invention, now in the start-up of apparatuses sterile per se, to carry out the digestion process   - in a first stage, a mixture of about four parts of aerobically digested compost and one part of organic waste materials is used, the compost preventing a decrease of the effective pH below 6.5 by temporary absorption of acids initially produced in excess, - after the initiation of a methane generation in a second stage, the proportion of the compost in the mixture is gradually decreased and the proportion of organic waste materials is correspondingly gradually increased to 100% and - only then is a mixture of exclusively organic waste materials of any type introduced.

Patent DE-3840462-A1 (DE)
Inventor: BERTHOLD FRITZ DR
IPC: G01N33/543
Filed: 1988-12-01
Abstract: In a method for measuring chemiluminescence by means of a photomultiplier (70), for example in immunoassays, the sample vessel (10), which is to be led past the measurement opening (71) of the photomultiplier, is subjected to the action of an essentially temporally constant magnetic field (40), the resultant force of which draws away from the entry window (measurement opening) of the photomultiplier the magnetic microparticles (20) which are located in the solution in order to increase the reactive surface, so that during measurement said microparticles are held outside the optical path of the chemiluminescence photons, and thus cannot attenuate the intensity of the signal to be measured. By contrast with previously known methods, in which the microparticles are separated from the sample to be measured, this solution enables the microparticles to remain in the solution even during the actual measurement process, thus saving, in particular with immunoassays, a few steps in the method and the problems connected therewith. <IMAGE>

Patent DE-3915482-A1 (DE)
Inventor: LINTNER ALEXANDER
IPC: B41F15/08
Filed: 1989-05-11
Abstract: The device for the synchronised individual drive of printing screens (4) of a rotary screen printing machine has, according to the invention, a pulse generator (9) for generating a digital signal (fm) corresponding to the speed of movement of a circulating printing blanket (3). A frequency divider (11), following the pulse generator (9), scales down the digital signal (fm) with a division ratio which can be determined from a master computer (10) and feeds the corresponding digital signals to the master computer (10). These digital signals are processed in the master computer (10) to form digital control signals, which are fed to a number of sub-computers (7) corresponding to the number of printing screens (4). In the sub-computers (7), the digital control signals are adapted to the requirements of the [lacuna] of stepping motors (5) with regard to their number of poles, angle-of-rotation elements and/or power requirements. The output signals of the sub-computers (7) are entered via power drivers (6), following each sub-computer (7), in the respective stepping motors (5), which consequently drive the printing screens (4) with an angular position (phase position) which is exactly constant with respect to one another. By means of keys (8), the command for adjusting the respective angular position by individual angular increments and/or for accelerating or braking individual printing screens (4) can be given to appropriately selected sub-computers (7). The major advantage of the invention over the prior art is that a constantly exact synchronised individual drive of printing screens is ensured without complicated intermediate angular gears and speed-superposing gears. <IMAGE>

Title: Motor vehicle brake system with anti-skid unit
Inventor: SCHIEL LOTHAR
IPC: B60T8/48
Filed: 1989-06-13
Abstract: The ABS braking system has a vacuum servo whose diaphragm (7) operates independently to the brake pedal input when wheel lock occurs. This is achieved by a hydraulic coupling (50) between the brake pedal linkage and the master brake cylinder. The coupling is separated from the hydraulic reservoir (11) by a control valve (46), thereby holding the brake pedal in a steady position during ABS cycling. The control valve is normally open, and is held closed by the ABS controller. This provides a failsafe brake control if any part of the ABS circuit is faulty.
