Abstract: A downhole tool having a diverter component for directing fluids in different directions within a wellbore. The diverter component has an outer pipe which forms part of the downhole string. The pipe has a through channel and holes through the wall of the pipe. Within the pipe is a sleeve which can be moved. In one position, the sleeve blocks the wall holes and allows fluid to pass through the channel of the pipe. The diverter component may be used in conjunction with packers to seal off sections of the wellbore. The diverter and packer assembly could be used to introduce acid into particular portions of the wellbore.

Abstract: An energy conservation system is disclosed wherein power in a given area, such as in a hotel or other room, is controlled by means of an ultrasonic sound transmitter and a plurality of ultrasonic sound receivers, each receiver controlling power for a separate power outlet. Upon entering the room, a key is inserted into a key receptacle to activate the transmitter and thereby cause the receivers to couple power to the power outlets in the room. When the key is withdrawn from the key receptacle, the transmitter signals the receivers to decouple power from the power outlets.
