A circuit controls the sound pressure level produced by a separate bass transducer in a multi-channel audio system having a number of upper frequency channels such that the perceived frequency response of the system remains substantially constant.
A chrominance signal constituting a color image is modulated to generate a modulated chrominance signal. A phase difference between this modulated chrominance signal and a signal corresponding to a particular color is detected. The saturation of the chrominance signal where the phase difference is small is enhanced, thereby making it possible to readily discern a portion of a particular hue from a surrounding portion having a hue different from that hue.
A method is provided for replacing an existing service pipe carrying fluid to an outlet within a property with a replacement service pipe. In the method the outlet is disconnected within the property from the existing service pipe in such a way that both during and after disconnection fluid is prevented from escaping into the property. A desired length of replacement service pipe is then fed into the existing service pipe in such a way that during and after the feeding step fluid is prevented fr...
Video processing for enhancing contrast includes detecting the ambient light levels on a display, performing local contrast enhancement processing to emphasize the luminance component based on the detected ambient light levels to provide a processed video signal, and presenting the processed video signal on the display.

Described herein is a method of enhancing signals received by a receiver in a mobile telecommunications network. The method comprises correlating the received signals to produce a correlation and making a selection from the correlation to create a replica for enhancing the received signals.
This invention is concerned with a method of prolonging the action of a medicament in a mammal by administering parenterally thereto an emulsion comprising an aqueous phase dispersed substantially uniformly throughout a metabolizable vegetable, animal or hydrocarbon oil containing one or more hydrocarbons of about 12 to 18 carbon atoms, the aqueous phase having an average particle size of about 0.1 to 10 microns and including an effective dose of a medicament. The medicament may be therapeutic o...
A vertically orientated body adapted to be clamp-mounted to the upper discharge end of a smoke or gas stack. The body rotatably mounts a vertically elongated shaft which incorporates an inclined arcuate hood thereover adapted to cover the stack and preclude the entry of water and down drafts. The hood is wind orientated through a vertical wind vane affixed thereto whereby the upper discharging portion thereof is always located downwind.
