Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an electrolytic cell comprising a cell frame having a plurality of electrolyte compartments, each compartment containing at least one pair of electrodes comprising an anode and a cathode.  Each of the electrode pairs has a hydraulically impermeable membrane disposed between the anode and the cathode separating each electrolyte compartment into an anolyte portion and a catholyte portion.  A space is provided in the electrolyte compartment to receive a portion of the membrane during operation of the cell, thus eliminating wrinkles in the membrane which are undesirable for various reasons, e.g. trapping of gas bubbles and allowing the membrane to vibrate during operation of the cell.

Abstract: TRANSFLECTIVE LIQUID CRYSTAL DISPLAY WITH   INTEGRAL HEATING UNIT AND TEMPERATURE SENSOR            ABSTRACT OF THE DISCLOSURE         A heated transflective liquid crystal display device has the heating element positioned behind the transflector to keep the heater out of the reflective light path.  This construction significantly improves brightness of the display in the reflective mode.         The heating element is positioned between the cell transflector and a temperature sensing thermistor.  The thermal gradient of the path between the heating element and the thermistor matches that of the path between the heating element and the liquid crystal cell.  As a result, the trip point of the heating element can be set much closer to the minimum cell operating temperature than hitherto possible thereby reducing the power consumption of the display.

Abstract: ABSTRACT OF THE DISCLOSURE         A known polarized electromagnetic relay (PE relay) has an I-shaped iron core with an energizing coil disposed with its ends between opposed end pieces of a yoke.  A movable block with permanent magnet structures at each end is provided with magnetic plates of the magnet structures between the core and the end pieces of the yoke.  Energizing the coil moves the block sideways to actuate contact members, the current direction determining the direction of movement of the block.  This known structure must be made precisely to ensure stable switching operation between its contact members and to avoid vibration.  Smooth switching is difficult to obtain and the structure tends to be fairly large.          The PE relay of the present invention avoids these problems by mounting the movable block and the magnetic structures supported thereby for pivoting movement which actuates the switching contacts.  The movable block can also tilt slightly to ensure good contact of the magnetic plates with yoke end pieces.

Abstract: A process for producing corrosion inhibiting particles comprising binding corrosion inhibiting anions to particles of an inorganic oxide by ion-exchange to form anion-exchanged particles, the anions of which are releasible by further ion-exchange in which the inorganic oxide particles having surface hydroxyl groups are first contacted with an acidic solution containing labile anions at a pH sufficiency below 7 for the protons of the hydroxyl groups to be replaced by the labile anions and thereafter contacting the particles of the labile anion-exchanged inorganic oxide with a solution containing the required corrosion inhibiting anions so that the labile anions are replaced by the corrosion inhibiting anions. The labile anions are anions of water soluble, acid compounds which have a lower affinity for the oxide surface than the required corrosion inhibiting anions and which form a soluble salt with the cation of the compound providing the corrosion inhibiting anions. The process facilitates the use of corrosion inhibiting anions which are sensitive to low pH in the preparation of corrosion inhibiting particles. In particular the process is useful for producing molybdate exchange inorganic oxide particles.

Abstract: A structural assembly includes a square trough-shaped stone having inclined external corner regions and a dovetailed groove formed in each wall side. The dovetail tongue of a connecting plate fits into the dovetailed groove. At the lower end of the internal surface of each wall of the stone, a shoulder portion may be provided for accommodating base elements. The height of the connecting plate is advantageously greater than the height of the trough-shaped stone, so that the plate projects beyond the stone in a vertical direction for connection to further stones. With such an assembly, it is possible to erect dry-stone type walls of various types. The individual elements of the assembly can be produced rationally and economically, and it is also possible to produce end elements and corner elements from the trough-shaped stones by cleaving the stones along grooves provided for such purpose.
