Hydrocarbon fuels, for example straight run gasoline and cat-cracked spirit, are up-graded by reacting the fuel with a hydrocarbyl hydroperoxide at a temperature greater than the decomposition temperature of the hydroperoxide and at a pressure sufficient to maintain the reactants in the liquid phase. The reaction may be carried out in the presence or absence of a metal catalyst for the decompositi...

A leak detector has a gas probe 1 for sensing signal gas escaping from an enclosure containing that gas at a pressure slightly in excess of ambient surrounded by a curtain of barrier gas. The reading of a gas analyzer such as a mass spectrometer depends on the height of the probe from the surface. A height sensor is attached to the leak detector and a programmable amplifier 6 contains information ...

An adjustable mammary prosthesis (10, 100) for augmentation mammoplasty is comprised of an outer teardrop-shaped, gel filled container or shell (12, 112). Disposed within the outer shell is a column-shaped container (19, 119) with a valve (20, 120). The projection (H1) of the prosthesis can be altered without altering the base diameter (B) of the prosthesis by adding an appropriate volume of fluid...

A radio communication system includes a transmitter unit, a transmission line and a receiver unit.
