Abstract: A security system comprises a plurality of alarm points distributed at a plurality of positions in a building; signal processing module for receiving alarm signals from at least an alarm point when alarm occurs at the at least an alarm point, transmitting the alarm signals to a server; a database for storing several sets of user information, map data, several sets of alarm point information; the server for receiving user requests from a plurality of clients, responding to the user requests according to the user information, the data map and the alarm point information, and then reverting responses to clients; the clients for sending the user request to the server and receiving and output responses. The present security system is of the advantage that it could be fully computerized and could satisfy the requirements of usage at the same time at several different sites by a plurality of different users.

Abstract: A building equipment control system comprises a remote transceiver module including a plurality of remote transceivers for remotely receiving multi-channel alarm signals, and each of the remote transceivers including a plurality of input points; a remote indication module including a plurality of remote indicators for performing alarm indication according to the multi-channel alarm signals, and each of the remote indicators including a plurality of output points; a remote main system controller for remotely setting characteristics and authorities of the input and output points; a remote compiler for remotely changing system settings of the remote main system controller and characteristics of the input points. The wiring of the system could save about 70-90% cables and 90-95% junction boxes, and reduce about 70% period of time for wiring and 90% period of time for testing and debugging needed for the conventional building equipment control system.

Abstract: The washer comprises an open-topped vessel having a tube mounted vertically and centrally therein. Post-primary bitumen froth is fed to the upper end of the tube. Pairs of down throw and up throw propellers mounted to rotate in the tube act to shear the froth as it passes down through the tube. At its lower end, the tube is closed off by a transverse wall. Slots are formed in the tube side wall to provide an exit. The sheared mixture thus changes direction as it leaves the tube. In the vessel chamber, solids and water sink downwardly and are removed as tailings through a bottom outlet. The sheared aerated bitumen rises and forms a new forth that is recovered in a launder. Middlings are withdrawn from the chamber and recycled to join the feed. The product froth is reduced in water and solids relative to the feed froth.
