A toggle-free scan flip-flop (TFSFF) is provided which is designed for use during a test mode scan operation. The toggle-free scan flip-flop has the capability of not toggling its parallel output during test mode scan operation. The TFSFF uses a master latch, which is controlled by a scan multiplexor, to selectively update two alternate slave latches. Switching logic controls the determination of ...

An improved composite material is produced by mixing ground gypsum and a plurality of host particles, each having accessible voids therein, together with sufficient liquid to form a dilute slurry; heating the slurry under pressure to a temperature sufficient to calcine the gypsum to calcium sulphate hemihydrate; allowing the calcium sulphate molecules to nucleate and form crystals in-situ in and a...

The present invention relates to an arrangement for suspension of a baking furnace for continuous production of carbon electrodes in direct connection with the smelting furnace wherein the electrodes are consumed.
