Title: Zeolite A, X, P and Y synthesis - with removal of part of water during hydrothermal process allows complete recycling of mother liquor
Inventor: STABENOW JOACHIM DIPL PHYS DR
IPC: C01B33/26
Filed: 1976-09-09
Abstract: Synthesis of zeolites of gps. A, X, P and Y involves hydrothermal treatment of mixts. contg. SiO2/Al2O3 and alkali and/or alkaline earth components and water in the required molar ratios, sepn. of the crystals from the mother liquor and re-use of this after addn. of reaction components. The novelty is that, during hydrothermal treatment, water is removed from the mother liquor in such amts. that this can be completely re-used. Water (vapour) can be removed by applying a vacuum, flash evapn. or by introducing a hot gas (e.g. air). E.g. in the prodn. of zeolite X, with removal of part of the water during crystallisation, the mother liquor was re-used several times. A well-crystallised prod. was obtd. in each case. Removal of water does not impair the quality of the prod. but reduces the crystallisation time, reduces the vol. to be filtered and allows complete re-use of the mother liquor, avoiding environmental pollution or costly processing.

Title: Electro-physical process esp. for moisture expulsion from masonry - uses multiple electrodes to produce several electrical fields
Inventor: TENGE HANS-WERNER
IPC: E04B1/70
Filed: 1977-02-14
Abstract: An electrode assembly for electro-physical processes comprises three or more electrodes, connected to power packs to provide a defined number of individual electrical fields; these fields amplify one another and together produce a total field. Used for various electro-physical processes, such as electro-osmosis, electro-kinetic processes, electrolytic processes and electro-phoretic processes. More specifically, it may be used for expelling water from a brick or similar wall by using low-voltage sources and embedded electrodes. By using a min. of three electrodes, comprising one true anode, one true cathode and a number of intermediates, much more effective electro-physical action is obtd. In partic., strip electrodes of conductive PTFE are used. (The effect of these is to eliminate the problems arising, on the one hand if high electrode voltage is used leading to electrolysis of the capillary water and destruction of the anodes, and on the other hand if low anode voltages are used, leading to passivation of the entire process.
