Patent ES-417090-A1 (ES)
Title: Method and apparatus for producing a distillate
IPC: B01D3/06
Filed: 1973-07-20
Abstract: A method and apparatus for distilling raw water, especially sea water or brackish water employing a combination of a multi-stage flash evaporator and a vertical tube evaporator. The water is preheated by passing it through condensers of the flash evaporator and is subsequently conducted through the flash evaporator stages to be partially evaporated and to have its resulting vapor condensed in the flash evaporator condensers. The raw water which has been preheated while passing through the condensers is delivered to a vertical tube evaporator where it is heated by steam. The vapor produced in the vertical tube evaporator is compressed by a hot water ejector and together with the excess vapor from the hot water ejector is used as heating steam. Part of the condensed heating steam is fed to the first distillate trough of the flash evaporator, the remaining part being returned to the water jet ejector motive stream.

Title: Intake manifold for internal combustion engine
IPC: F02M35/112
Filed: 1976-04-15
Abstract: The intake manifold for supplying air-fuel mixture from a single source to a plurality of cylinders of an internal combustion engine employs individual pipes all having the same cross sectional area but having different non-circular cross sectional contours. Where less fuel is needed at low engine speed and power output, the bottom half of each intake pipe is formed with a smaller internal radius of curvature than the top half. Where more fuel is needed at low engine speed and power output, the bottom half of each pipe is formed with a larger internal radius of curvature than the top half. The purpose is to better equalize the distribution of fuel to the cylinders under low speed and low power operation of the engine, without affecting fuel distribution at higher engine speeds.

Patent ES-466497-A1 (ES)
Title: Melting of fine particulate material in a high-speed rotary furnace
IPC: C21B13/08
Filed: 1978-01-31
Abstract: Finely divided particulate material is discharged against the incandescent wall of a rotary furnace through a pipe extending into the open end of the furnace in a position where the material is out of the path of the flame projected into the furnace through the open end and out of the path of the outflowing gases. The material is retained against the interior wall of the furnace by centrifugal force and, as the material melts, it collects in a pool at the inner end of the furnace.
