When transmitting signals to the respective two paths having a routing length difference on a transmitting side, a signal identifying one and the other of the respective two paths is given to the transmission signal before transmission to one and the other of the paths. On the receiving side, after the two paths have been intentionally switched in the state of non-instantaneous disconnection from one path to the other under external control, a change from the signal identifying one of the paths ...

A method and a computer program product, implementing techniques for exchanging data in an unattended desktop sharing mode. The techniques include receiving a conferencing request, at a local unattended server, from a remote conferencing server; loading a desktop application on the local unattended server in response to the conferencing request to generate a loaded desktop; sending the loaded desktop to a virtual device to create a shared desktop; and sending the shared desktop to the remote con...

An assembly and method is provided for a tripping mechanism of an circuit breaker to limit the damage to a protected circuit breaker and other associated equipment such as enclosures, bus way, etc. from the high forces that result from high currents and prevent unwanted tripping of a circuit breaker due to rapidly decreasing currents. A trip system for a circuit breaker including a sensor to determine a rate of change in the current level. A positive detector is connected to the sensor to determ...

A method for determining the instantaneous temperature of a medium, the medium surrounding an element able to be electrically heated at least intermittently to a constant, known temperature. It is provided for the instantaneous temperature of the medium to be determined from a heating power supplied to the element.

A process for instantaneous peptization of polychloroprene latexes made by polymerizing in the presence of sulfur and a modifying agent such as iodoform or a dialkylxanthogen disulfide, by adding a suitable thiol at a pH at least equal to 9.

Apparatus for making an instantaneous or flying scarfing start on a moving metal workpiece, including: A. a wire feed mechanism for feeding and contacting a spot on the workpiece where the reaction is to begin, with the end of the wire, B. a mechanism for preheating the end of the wire to its oxygen ignition temperature, C. a blowpipe for discharging a high intensity jet of oxygen at a point on the workpiece behind said spot, and D. a scarfing oxygen nozzle, directed at the workpiece at an acute...

An instantaneous water heater includes a heating tube, a heating device over a lower end of the heating tube, a spiral pipe held in the heating tube, water inlet and outlet pipes connected to two ends of the spiral pipe, a water-discharge switch installed on the other end of the water outlet pipe; the heating tube is made of metal, and emptied of air, and it contains heat media, which will vaporize into gas rapidly when heated by means of the heating device; the heating device isn't powered usua...

A method of determining whether a winning entry exists in a bingo game with a large number of entrants includes providing entry cards where the spaces on the cards containing numbers are divided into two or more groups. The symbols in the spaces of a group are arranged in patterns and patterns appear on more than one entry card. As numbers are selected as winning numbers in the bingo game, they are compared with a map of all patterns. If winning patterns are found to exist, the set of winning pa...

Unknown alignment biases of sensors of a tracking system are estimated by an iterative Kalman filter method. Current measurements are corrected for known alignment errors and previously estimated alignment biases. The filter time reference is updated to produce estimated target state derivative vectors. A Jacobian of the state dynamics equation is determined, which provides for observability into the sensor alignment bias through gravitational and coriolis forces. The target state transition mat...

In a hot and cold water distribution system wherein the hot water is delivered from a water heater to a distant hot water tap adjacent to a cold water tap, a hot water recirculation pump assembly purges the hot water line of any cooled-down water in order to assure instant hot water delivery when the hot water tap is opened. The volume of water drawn from the hot water line is, in a first embodiment of the invention, cooled down through a radiator before being recirculated through the cold water...
