Title: Device for accurate measurement of the dimensions of an object by ultrasonic waves
IPC: G01B17/00
Filed: 1976-04-14
Abstract: In a device for accurately measuring the dimensions of metallic tubes and the like by supersonic waves in a liquid medium, typically water, obstructions providing reflecting boundaries that are partially reflecting and partially transparent for acoustic waves are provided at different distances from the transmitter-receiver between the latter and the object being measured and echoes of transmitted pulses from the reflecting boundaries of the obstructions and from those of the object being measured are processed in order to obtain the measured dimensions in a manner unaffected by changes in the velocity of propagation of the waves in the liquid medium because of temperature effects and the like. The pulse processing involves obtaining electrical signals proportional to the time delay between pairs of pulses and then comparing the time delays relating to precisely known distances with time delays relating to distances being measured. When the tube being measured is empty or otherwise filled with a poor medium for acoustic transmission, transmitter-receivers are provided on opposite sides of the tube and for checking fully the uniformity of tube thickness and diameters. A pair of cylindrical shells of diameter greater than the tube extending part way only into the path of the ultrasonic waves most conveniently provides the obstructions of precisely known dimensions.

Title: Method and apparatus for manufacturing fresh water from salttcontaining raw water
IPC: B01D1/28
Filed: 1978-07-07
Abstract: In a desalination plant, the fresh water vapour produed by the evaporation of the raw water is compressed adia-batically and condensed by isobaric cooling. The heat released by the condensation is transferred to the raw water. The mechanical work of an internal combustion engine is used for the adiabatic compression and the engine waste heat is also transferred to the raw water. This results in a much better overall thermal efficiency of the process, with a much lowe ratio of energy consumption to fresh water yield.

Patent ES-8206363-A1 (ES)
Title: Web tension control method and apparatus
IPC: B65H19/14
Filed: 1981-10-21
Abstract: This invention provides an improved method and apparatus for controlling the tension in a tensionally fragile web of material being pulled by a constant speed processing machine from either one of a pair of supply rolls. A first festooning roller effects the control of the web tension during the normal operation of the machine. During the splicing of the web from one supply roll to another, the tension in the web would tend to dramatically increase. This tendency is offset by a second festooning roller engageable with the web and shiftable in a web tension decreasing direction only upon the occurrence of web tensions substantially in excess of the normal tension range. Means are provided to restrict the rate of return movement of the second festooning roller to that which falls within the control limits of the first festooning roller, thus eliminating any tendency to accelerate the new supply roll to a speed above the desired machine operating speed.
