setting and density factor used during an actual patient exposure. A basic compensation curve is called up in response to the user selecting a tube kV and mA. The ordinates of the basic curve are multiplied by the gain factors. The results are ac- ted on by an algorithm that yields a corrected compensation curve and the data are put in a memory device in the form of binary representa- tions of reference voltages versus exposure times. During an exposure the reference voltages are clocked out in time sequence and compared with the integrated dosage signal. When a com- parison is made, the exposure is caused to ter- minate.

METHOD FOR SAMPLING A FLUID FROM A WELL

Paul J Brunner, Charles A Christopher, Robert G Pindell assigned to Texaco Inc

A method for sampling a fluid, as a multi-phase chemical product as liquid chemical tracers from a well in a field of wells comprising basically (1) injecting a sample of the liquid from the well through a plurality of valves, as solenoid valves on a plurality of liquid containers, and (2) con- trolling the well liquids responsive to a timing switch, as a stepping switch, through the valves into the liquid sample containers to be filled one after another, periodically, and consecutively from the well in a prearranged order for pro- viding an improved method that is more ac- curate and more precise.

less complex, discharges less waste oil that damages the environment from the single well, and that indicates the arrival of the multi-phase well fluid at the production well from an injec- tion well and/or the arrival of various chemical concentrations thereof thereafter.

APPARATUS AND METHOD FOR ENERGY CONVERSION

Stephen Horvath, St Ives, Australia assigned to Beeston Company Limited

Process and apparatus for liberation of energy by controlled nuclear fusion reaction involving isotopes of hydrogen gas. Highly ionized hydro- gen gas containing a higher proportion of deuterium than in naturally occurring hydrogen is pressurized, together with an oxidizing gas within combustion chamber of reciprocating piston and cylinder engine. An electrical dis- charge within the combustion chamber causes generation of heat by atomic dissociation and ex- othermal recombination of hydrogen atoms and electrical excitation of ionized gas. Ionized deuterium in the hydrogen gas undergoes a nuclear fusion reaction with consequent libera- tion of heat energy and remaining hydrogen gas burns in the oxidizing gas to provide control on fusion reaction. Apparatus for producing ionized hydrogen gas in appropriate form by treatment of normal industrial hydrogen gas is disclosed, and also gas mixing apparatus for mixing the ionized hydrogen with atmospheric air as the oxidizing gas.

TIME INTERVAL AUTOMATIC WELL MULTI-PHASE FLUID

SAMPLER

Paul Brunner, Charles A Christopher, Robert G Pindell assigned to Texaco Inc

An automatic multi-phase well fluid sampler comprises an inlet solenoid valve means on each of a plurality of sample containers for receiving multi-phase well fluid such as a produced oil- water fluid from one of a plurality of wells, and each of the inlet valve means being responsive to a timing and stepping switch means for precisely filling its sample container periodically, in con- secutive order, from the same well for providing an improved well sampler system that is more ac- curate, more precise, more readily adjustable,

LIQUID METAL SOLAR POWER SYSTEM

Bobby J Tammen

A solar power system for cogenerating heat and electricity is disclosed. An improved solar collec- tor includes a transparent reflector envelope through which a reflective liquid metal such as mercury is circulated. The liquid metal is pre- heated as it focuses solar radiation onto the receiver of the collector module. A baffle tube within the receiver is perforated to permit the cir- culation of working fluid out of the absorption chamber of the receiver into the narrow annulus
