Patent ES-443423-A1 (ES)
Title: Method and apparatus for monitoring the flow of liquid and the like
IPC: G01S15/58
Filed: 1975-12-11
Abstract: A method of measuring the speed of flow of a liquid along a conduit by omitting a continuous acoustic signal of known frequency through a wall of the conduit and receiving the signal reflected, from the liquid. This reflected signal is of increased frequency due to the Doppler effect, and the received signal is demodulated to give a signal at the Doppler difference frequency which is a function of the liquid speed. The Doppler difference frequency is divided by a divisor of known numerical value and the quotient frequency counted. This quotient frequency is a function of the speed of flow or the flow rate, and one or more indicator devices utilize this count either as analogue signal or integrated with respect to time to indicate the instantaneous speed or flow rate or the total volume or weight of liquid which has passed.

Title: Liquid-semiconductor junction photocells
IPC: H01G9/20
Filed: 1977-11-08
Abstract: Liquid-semiconductor photocells using chalcogenide semiconductors have been advanced recently to the point where they compete favorably with silicon devices for solar power conversion. However, in common with silicon devices, the semiconductor needs to be a single crystal. This fact makes solar power impractically expensive. According to this invention, the chalcogenide semiconductor is made by anodizing cadmium or bismuth in a sulfide, selenide or telluride electrolyte. The anodized element, when operated photovoltaically in an electrolyte similar to the anodizing solution, produces useful power conversion and is relatively inexpensive.
