Abstract: This invention relates to a telecommunication control switching device (1) and method for controlling the power supply to an electrical device (8) through a telecommunication network (3). A device (1) of the present invention is connected between the telecommunication line (3) and a piece of telecommunication equipment, such as a telephone, as well as being connected between a mains supply (6) and an electrical appliance (8). The device (1) provides a switched mains outlet, and monitor given conditions in the telecommunications lines (3)/telecommunication equipment. The device (1), therefore, enables the electrical appliance (8) to automatically be switched on or off when those given conditions such as a ringing signal or off-hook situation in a telephone set, occur.

Abstract: A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor extends beyond the input port to deflect solid particles thereby reducing jams and preferably is a dual-flow rotor, directing molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members with a flexible disc disposed therebetween. Another aspect of the invention is a housing for a transfer pump that includes a discharge leading to an output port and a button adaptor extending from the discharge.

Abstract: A heat recovery and pollution abatement process with stackless operation for removing the products of combustion from hot boiler flue gas (45) comprising the steps of passing said hot boiler flue gas through a cloud of steam or mist (46), cooling the hot moist flue gas and recovering the heat therefrom (47), passing the partly cooled hot moist flue gas through a second cloud of mist comprised of cold water to total saturation (48), collecting the resulting stream of acid water, forcing the treated flue gas, mixing the treated flue gas with outside air, directing the forced treated air to atmosphere, shutting off the process in the absence of boiler flue gas.

Abstract: A carrier, as used for example to transport several radio frequency identification devices, includes a circuit having an antenna and a series capacitor for tuning the antenna. Enhanced transceiver communication results when transceivers are placed in the carrier. Alternately, a carrier may include first and second antenna circuits, each having a capacitor for tuning the respective antenna. The two circuits may cooperate so that energy received in a first pattern is re-radiated in a second pattern for further enhanced transceiver communication, such as detection of the presence of the RFID device within the carrier.

Abstract: A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, a chamber wall, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor is a dual-flow (or mixed-flow) rotor, directing molten metal both into the chamber and towards the chamber wall, where it ultimately exits the chamber through the discharge. The dual-flow rotor can also be used with a scrap melter.

Abstract: A perimeter monitoring system is arranged to detect passage across a perimeter of an area. The system primarily includes an emitter, a retroreflector, a detector and an alarm. The emitter provides a modulated visible laser beam. The retroreflector is arranged to direct the beam along a segment of the perimeter and return the beam along the segment. The detector includes a device that blocks reception of light outside an angle of less than 5 degrees. One or more local or remote alarms are activated in response to the signal. For example, a remote alarm is located on the inside of a residence window where it is activated by another visible laser beam. Alignment of the peripheral monitoring system is less costly and false alarms are less likely than with known systems.

Abstract: An improved TCAS indicating system and method for displaying information from the MODE S TRANSPONDER or other subsystem, directly to the TCAS DISPLAY by coding the information and programming the TCAS COMPUTER and the MODE S TRANSPONDER to pass the coded information through to the TCAS DISPLAY.

Abstract: An apparatus that permits a rotatable wing to be operated in three modes: a first orientation mode, a second orientation mode, and a mode in which the wing rotates (called the rotating mode). The apparatus permits the wing to be stowed and used in both fixed-wing flight and rotary wing flight. The apparatus may be a component of an aircraft capable of fixed-wing flight with a fuselage oriented generally in the direction of flight. In the first orientation mode, the wing is generally parallel to the orientation of the fuselage, providing a relatively compact stowage configuration. In the second orientation mode, the wing is generally perpendicular to the orientation of the fuselage. The first orientation mode thus facilitates stowage of the wing during stowed flight of such an aircraft under power of a host aircraft, the second orientation mode facilitates fixed-wing flight, and the rotating mode facilitates rotating-wing flight. The wing may be started into auto-driven (i.e.
