Title: Water hardness sensor for water softening plant - with tandem pairs of electrodes supplied with high frequency voltage
Inventor: JOHN CLAUS
IPC: B01J47/14
Filed: 1976-06-10
Abstract: The water softening operation in ion exchange water treatment plants is controlled by two measuring points for the electrical resistance of the water which are connected to a brige circuit and initiate the regeneration when the softening cpd. is spent. The pairs of measuring electrodes are arranged in series in the direction of flow and are supplied with a high frequency AC voltage pref. 3 kHz. This results in a very simple arrangement of the electrodes, if the electrode pairs have one common central electrode. The high-frequency voltage prevents undesirable electrolytic dissociation resulting in deposits of iron and iron cpds. on the electrodes.

Title: Double glazed window structure assembly system - delivers glue by nozzle between panes and frame to fill slot completely
IPC: E06B3/64
Filed: 1978-05-02
Abstract: The system assembles an insulating glass structure, a set of panes being stacked flat with intervening distance pieces all the way round their edges, so as to form air spaces between adjacent panes. The set is then fitted to a prefabricated and torsionally rigid metal window frame which has an L-shaped surface to retain it. A sealing distance piece is then fitted all round the free edge of the surface, between it and the pane edges. The slot formed is filled with insulating elastic glue to give a hermetic seal for the air spaces and secure the panes in place, and which is allowed to harden. The glue is delivered into the slot from a narrow nozzle inserted right to the bottom of the slot, filling the latter completely with glue right to the top. At the same time the injector is slid along the slot, so as to form a monolithic mass of glue.
