Filed: 1987-06-15
Abstract: A machine washing process with process-controlled dosing of water and detergent using a paste-form, phosphate-reduced or phosphate-free detergent which is substantially free from water, organic solvents and hydrotropic compounds. The paste comprises a phase liquid at a temperature below 10 DEG  C. and contains a nonionic surfactant selected from the group of polyglycolether compounds and of a solid phase dispersed therein in which the particles have a mean particle size of from 5 to 40  mu m and less than 5% of the particles have a particle size larger than 80  mu m, the solid phase comprising washing alkalis, sequestering compounds and other detergent constituents and, optionally, anionic surfactants. Under the control of a process-control computer, the paste is taken from a storage container, delivered to a mixer and diluted therein with water to at least such an extent that the formation of a gel phase is avoided. The aqueous mixture is fed to a washing machine and, unless this has already happened in the mixer, is diluted with more water to a concentration of 0.5 to 10 g/l, after which the washing process is started.

Patent DE-3731012-A1 (DE)
Title: Ignition circuit tester having a display which is stable despite climatic effects
Inventor: SOBBE FRIEDRICH-WILHELM
IPC: F42C21/00
Filed: 1987-09-16
Abstract: In order to measure the resistance of individual bridge-wire detonators, of detonating cables or of entire detonating circuits, an ignition circuit tester is used in which the LCD display has an analog-digital converter connected upstream of it, which converter is connected through a changeover switch which is allocated to the connecting terminals, such that it reverses the polarity of the measurement and external impedance. In consequence, climatic influences have no effect on the measurement of the readings or on the measurement process, so that accurate readings can in each case be measured, for example, even when there is a risk for the detonating cables of synthetic insulation ceasing, as a result for example, of gas formation or bubble formation, at bare points. <IMAGE>

Title: Method for conveying viscous fermentable media and pneumatic conveying device
Inventor: FRESE CHRISTOPH
IPC: F04F1/14
Filed: 1987-10-27
Abstract: This invention relates to a method for conveying viscous fermentable media and a pneumatic conveying device which can be used for this method. The method is characterised in that the medium to be conveyed is initially introduced via a first pipeline (105) to a pressurised container (20) until a predetermined upper level has been reached, then the pressurised container is pressurised with compressed air and the pressurised container is evacuated via a second pipeline (100), the compressed air displacing the medium to be conveyed until a predetermined lower level has been reached, the air pressure in the container then being lowered to a predetermined desired value, after which the pressurised container is again filled with the medium to be conveyed. The method according to the invention has the advantage that the occurrence of powerful currents or turbulence in the medium to be conveyed is prevented. The pneumatic conveying device according to the invention does not have any mechanical moving parts which come into contact with the conveyed medium during the conveying process. The conveying device can, for example, be used to convey liquid manure of sewage sludge, even when they contain solids or foreign bodies. <IMAGE>

Title: Engine and machine with a positive displacement effect
Inventor: WITTMANN HELMUT R W
IPC: F02B75/16
Filed: 1989-01-02
Abstract: The axial-linear guidance of a reciprocating piston rod (21) in a driving mechanism is achieved by the eccentric mounting of a shaft (1) with complete balancing of the oscillating and rotating masses and controlled by a simple epicyclic gear mechanism (11). The change of working fluid is effected by the constant rotation of a rotary slide/rotary sleeve combination (4) which periodically opens inlet and outlet openings (3) in the cylinder wall and cylinder head. Large opening cross-sections and short fluid paths ensure optimum filling, complemented by axial and radial stratification, swirling and exhaust gas recirculation in the case of internal combustion engines. A multiplicity of drive systems ensure low-loss driving (5) of the fluid control system and simple control of the timing angles. Various different pistons (2) with a large connecting-rod ratio starting from 1:2, integral piston-head cooling and minimum piston and connecting rod mass provide compact driving mechanisms for very high speeds of rotation and variable compression. Further characteristic features are: sufficient space for multiple ignition, a pressure-stable cylinder head, a minimum of components for plug-in assembly, very high pressure compression for self-ignition, internal or external combustion, precision compensation of position deviations and modular construction with five basic units. <IMAGE>

Title: Device for directly structuring circuit carriers
Inventor: FLORJANCIC MATJAZ DR
IPC: G03F7/20
Filed: 1989-03-30
Abstract: By directly structuring circuit carriers, e.g. printed circuit boards, by means of laser light, the photomasks which are conventionally used for producing printed circuit boards, become redundant. In known devices for directly structuring, mechanically displaceable mirrors are used for deflecting the light beam for picture element scanning, which mirrors are difficult to produce and which are complex to drive. The technical problem to be solved consists in avoiding mechanically moved parts when directly structuring circuit carriers. The solution consists in arranging in the beam path between the light source 2 and the light-sensitive layer 20 a row 17 of light gates, whose light transmission is controlled by the control device 3. It is advantageous for the row 17 of light gates to be produced from a PLZT-ceramic material and to construct the control device 3 as CAD system. This results in a good flexibility and short turnaround times during the production of printed circuit boards. <IMAGE>
