Abstract:
Various arrangements for remotely manipulating a wire may be presented. A wire pilot may be presented that is configured to be coupled with the wire and to move in response to a magnetic field created by a remote guide when the wire pilot is within a wall and the remote guide is external to the wall. The remote guide may include a magnetic field generator configured to create the magnetic field and a metal detector configured to detect wires through a wall.

Abstract:
A thermal power generation apparatus comprises a boiler (15) and multiple turbine sets for high, intermediate and lower steam pressure operation. Steam exhausted from the high pressure turbine (HP), and reduced in both pressure and temperature, is returned to a reheater (19) for reheating. The reheated steam is then passed to a intermediate pressure turbine (IP). It is desirable to control the temperature of steam entering the intermediate pressure turbine (IP). The invention provides a system for effecting temperature control of the reheater stream in a thermal power plant. The system includes a reheater conduit (10, 21) adapted to define at least a part of a reheat flow path for steam between an exhaust of a high pressure turbine system (HP) and an inlet of a reheater system (19). The system further includes an indirect water/steam heat exchanger (B) having a heat exchange portion within the reheat flow path and defining a water flow path means adapted to receive and circulate feed water. The feed water may be taken from take off points (A, D) in the primary feed water stream.
Abstract:

Abstract:
An ADC and method comprises a hybrid-type sigma-delta modulator comprising a digital delta-stage and an analog sigma-stage, wherein the analog sigma-stage comprises an analog low-pass filter adapted to only pass a low frequency audio band between 0-20 khz of a PWM wave, and wherein the digital delta-stage comprises a PWM wave generator; a pair of MOSFETs; and a power supply unit outputting voltage to the pair of MOSFETs. The ADC comprises a comparator attached to the hybrid-type sigma-delta modulator; a low-pass filter configured in a digital domain and for receiving a signal output of the comparator and remove high-frequency components of the comparator output above the audio band; a PWM back converter adapted to receive the filtered signal output and translate the digital low-pass filtered signal output to a power supply transient value in a digital format; and a dither signal source for injecting a dither signal to the digital delta-stage.
