Title: Rotary Electric Pump
IPC: H02K5/167
Filed: 1967-03-10
Abstract: In an electric motor-pump in which the pump impeller 13 is mounted on the same bearing bush 8 as the planar motor rotor, the bearing is of a material, e.g. graphite or ceramic, lubricated by the pumped liquid, and the pump delivery is controlled by a cup-shaped baffle 15 which may be moved axially by rod 18 against spring 22, to regulate the amount of liquid passing back from the outlet side of the impeller to its inlet.

Patent ES-457771-A1 (ES)
Title: Heat transferring method
IPC: D02J13/00
Filed: 1977-04-13
Abstract: In the transfer of heat between a running filament yarn and a medium, the yarn, twisting on its long axis is led through an axially parallel stream of air whirling in the opposite direction to that in which the yarn is being twisted. Heat may be imparted to or extracted from the yarn, and two whirling streams of air may be used to transfer heat to and take heat up from the yarn successively, before the yarn is subjected to a false twisting operation. The quality of the yarn is improved by blowing the whirling compressed air in the opposite direction to that in which the yarn is being twisted, and a suitable device for generating whirling stream of gas described in DT OX 2546708 has a chamber with tangential inlets arranged round the circumference of the chamber. At the sides there are an ilet and an outlet tube, so that the whirling action can be maintained, the tubes being long relatively to the chamber. The yarn can thus be kept in contrast with the whirling air for a comparatively long period and the ends of the tube farthest from the chamber are constricted.

Patent ES-473488-A1 (ES)
Title: Dry cooling power plant system
IPC: F28B9/06
Filed: 1978-09-19
Abstract: A power plant system utilizing a zoned or multipressure condenser or cooling tower whose different zones are air-cooled in a dry manner. The zoned condenser may condense motive cycle fluid by passing it directly through air-cooled heat exchange conduits or by passing a dense fluid through an intermediate, zoned condenser where it boils as it absorbs heat from the cycle fluid and then through the aforementioned zoned, cooling tower. A separate coolant circuit is used between each intermediate condenser zone and the cooling tower. Each intermediate condenser zone is maintained at a predetermined pressure by the coolant flowing through one of the coolant circuits and transporting heat therewith from the intermediate condenser to air flowing through the dry cooling tower. To obtain different boiling and condensing temperatures in the coolant circuits different coolants or different coolant pressures must be utilized therein. The coolant circuits are preferably arranged in the dry cooling tower in series airflow relation in the order or increasing coolant circuit temperature along the direction of normal cooling air flow. Zoned, multi-pressure condensers increase efficiency of the power plant system while the use of such dense, boiling coolant can decrease the surface area required in the intermediate condenser and cooling tower and reduce the amount of coolant that must be circulated therebetween.
