Patent DE-3725386-A1 (DE)
Inventor: CHAFIK EFAT DR
IPC: C02F1/52
Filed: 1987-07-31
Abstract: 1. A method of treating waste water from flue-gas purification plants, constituents being precipitated by adding precipitation and floculating agents and the sedimented sludge being separated from the supernatant water and subsequently dewatered in a separate stage and salts such as calcium chloride or sodium sulphate dissolved in the supernatant water are converted to usefull salts, e.g. sodium chloride, in batches by adding suitable double decomposition substances, e.g. sodium carbonate or calcium chloride after the sludge separation, characterised in that the batchwise double decomposition process is carried out in two steps, i.e. a first step in which 80 to 90% of the amount necessary for double decomposition and calculated by a first analysis is added through a volumetric metering system, after which a second analysis of the waste water is made and subsequently, in a second step, the remaining amount necessary for complete double decomposition is added through a gravimetric metering system.

Patent DE-3800155-A1 (DE)
Title: Inclinometer
IPC: G01C9/20
Filed: 1988-01-07
Abstract: For the rapid and accurate measurement of angles, even in the case of an inclined position of the measuring plane, as well as in a special design for detecting this inclination itself, it is intended to provide a solution which works with a liquid which follows gravitational force. This object is achieved by a specific separation of the side walls of the liquid container, so that cohesive forces hold the liquid surface together, even in an inclined position, to form an optical line which can be assigned to an angular scale which can be rotated for calibration. By means of a further conversion of the container, the simultaneous measurement of an angle in the third dimension is possible.

Title: Recirculation piece for connecting a dialyser on the patient's side, and method of cleaning and venting such a dialyser
Inventor: SCHULZ-LAUTERBACH ACHIM
IPC: A61M1/36
Filed: 1988-10-26
Abstract: The invention proposes a recirculation piece 8 for connecting a dialyser on the patient's side, in which two flexible tubes 81 and 82 which are each provided with one male and one female Luer lock 85 and 86 at the ends, are connected by means of a tube 83 that can be shut off. At the same time, this connecting tube 83 can be shut off in the same way as one side 82a of a flexible tube 82. Such a recirculation piece can be used to carry out a method of cleaning and venting a dialyser 6 and its lines 3 and 4 connected to the patient. For this, a predetermined amount of physiological saline solution is circulated, with supplementation of the amount of solution exchanged in the dialyser 6, in the closed system through the dialyser 6 and the connecting lines 3, 4, and the circulated amount of solution is fed to a receptacle 2 after a predetermined circulation time after shutting-off the circulation path. <IMAGE>
Patent DE-3837839-A1 (DE)
Title: Propellant charge casing having a permeable shaft
Inventor: BONGERS HERMANN DIPL ING
IPC: F42B5/26
Filed: 1988-11-08
Abstract: In order to reduce the production costs of propellant charge casings, a large number of passage openings are incorporated in the radial direction in the shaft of the propellant charge casing. When the projectile is fired, the hot powder gases flow through these openings into the annular space between the outer wall of the propellant charge casing and the inner wall of the firing chamber (rear part of the firing barrel) and thus relieve the pressure on the shaft of the propellant charge casing. The seal on the breech side of the firing barrel is shifted from the casing mouth to the casing base. The reduction in the production costs is achieved by:   1. Reduction in the material costs. Cheap perforated sheet metal or metal mesh can be used for the shaft. 2. Reduction in the manufacturing costs. The propellant charge casing is designed in two parts.   The casing base can be forged in a die and the shaft can be designed using a welded structure. The propellant charge casing according to the invention is a component of a cartridge for conventional tube weapons, but not for recoilless tube weapons or tube weapons with low recoil.
