If the absorption distribution in only a part, for example a separate organ, of a body section under examination is required, the overall radiation dose administered to the body can be reduced. The part region 11 is irradiated with the full intensity by a beam limited 11a 11b to the width of the region 11 during a first measurement cycle. In order to avoid reconstruction errors, the entire body sl...

A control process for a rotary pump which is immersed in a fluid produced by a well involves the use of a rotary pump driven by a variable speed motor and comprises the steps of acting upon the rotational speed of the motor according to a pressure difference which exists between the pressure of the fluid measured in the proximity of the pump and the production pressure of the well. The production ...

Metallic droplets in liquid, solid or partially solidified form are deposited onto a substrate to produce cast or coated articles by utilizing the Coanda Effect to draw one stream of gas toward another stream of gas flowing over a surface and introducing molten metal between the two gas streams such that the molten flow is broken into droplets. In the embodiment primary fluid flows through slit 50...

An electricity billing recorder has a controller for processing pulses from an electric meter. The resulting data is temporarily stored in random access memory as data words representative of energy consumed in predetermined time ("demand") intervals. The accumulated measurement ("event") data and time data are transferred to a non-volatile, solid state memory module after relatively long collecti...
