Title: Membrane system for ultrafiltration etc. - formed from two flat membrane sheets with support between sealed at each side to create three separate flow passages
Inventor: KNOTHE ERICH
IPC: B01D63/14
Filed: 1978-11-30
Abstract: Mass transfer between two fluids is carried out across a pair of membranes held apart by a woven or non-woven web of plastic fibres. The membranes are folded over on each other to create a series of folds. Each end and side is sealed. Sealing arrangement creates two separate flow passages on either side of the membranes element each with their own inlet and outlet branches. A further fluid stream is passed between the membranes, depending on the type of process involved. Used in various blood treatment processes such as dialysis in artificial kidney machine or oxygenation in artificial lung. Arrangement allows several operations, such as dialysis or ultrafiltration to be carried out on one machine. Also allows the capacity of the machine to be adjusted for patients of different body weight.

Title: Accumulator battery state continuous measurement and indication - using subtraction of positive sum voltage from negative reference and inverting operational amplifier, with difference fed to indicator
Inventor: NANN EBERHARD DR PHIL
IPC: H01M10/44
Filed: 1978-12-04
Abstract: The charge condition of an accumulator battery is measured by the summation of a battery terminal voltage and a measuring voltage, tapped at a shunt resistor randomly connected in the discharge circuit, with amplification of the measured values. The positive summation voltage is subtracted from a negative reference voltage. When the summation voltage has dropped below the preset reference voltage value, a negative difference voltage is inverted in a stage formed as a operational amplifier. This voltage is supplied to a display controlled in dependence on the difference voltage. The display is preferably formed by a light spot control component, switching the individual spots in response to the difference voltage. Additional amplification of the difference voltage may be carried out in an operational amplifier functioning as a subtractor, which operates with an adjustable amplification factor. The reference voltage may be adjusted between 100 and 40% of the battery charged condition.
