Patent ES-471599-A1 (ES)
Title: Combination ion exchange and electrodialysis fluid purification apparatus
IPC: B01D15/04
Filed: 1978-07-10
Abstract: An illustrative embodiment of the invention converts a feed solution stream into three separate streams of concentrated acid, concentrated alkali and deionized liquid, respectively, through a combination of ion exchange and electrodialysis techniques. Typically, feed fluid from the primary coolant loop of a nuclear reactor that contains ionized boric acid and lithium -7 hydroxide flows into a bed of mixed anion and cation exchange resins. Two of the walls of this bed, however, are of anion permeable and cation permeable membranes respectively, to permit the anions to migrate into an anolyte compartment and to permit the cations to migrate into a catholyte compartment. Within the anolyte compartment there is an anion resin bed which purifies the borate ions from other contaminative anions. Within the catholyte compartment there is a cation resin bed which purifies the lithium ions from other contaminative cations. Appropriately selected anion permeable and cation permeable membranes for the other sides of the catholyte and anolyte compartments, respectively, allow sufficient ion migration to permit a degree of chemcal recombination. The final products from these three flow paths are concentrated boric acid, concentrated lithium hydroxide and deionized water from the respective analyte, catholyte and feed fluid compartments.

Patent ES-8205701-A1 (ES)
Title: Feeder for fruits and the like
IPC: A23N4/18
Filed: 1981-02-12
Abstract: A hopper for feeding fruit in several transversely spaced lanes from a supply conveyor to the pick-up positions of a fruit feeder includes several drums mounted in spaced and downwardly inclined relationships. The spacing between the adjacent drums is adapted for the reception of a single file of fruit, and the inclination of the drums is sufficient to cause the fruit to gravitate downwardly to the feeder pick-up positions. A push-pull drive mechanism is provided to pivot the drums back and forth about their axes of rotation to cause the fruit to spin as they gravitate downwardly between the drums. Such spinning action facilitates rapid feeding of the fruit downwardly between the drums and, in particular, prevents irregularly shaped citrus fruit such as tangerines or lemsons from becoming enlodged against each other to thereby interrupt their flow to the pick-up positions.
Patent ES-8403258-A1 (ES)
Title: Power-line baseband communication system.
IPC: H03M5/16
Filed: 1983-03-10
Abstract: A communication system for transmitting baseband digital signals on an electrical power line. A pulse generator produces digital signals which are limited to a frequency spectrum of 30 kHz to 300 kHz and applied directly, i.e., without modulation, to an electrical power line. At the receiving terminal an amplifier compensates for attenuation characteristics of the electrical power line and the received signal is then sampled to extract the information from it. To avoid interference when both a transmitting and receiving link are located at a substation, the baseband system incorporates a mimic network to mimic the interference signal erroneously picked up by the receiving link from the transmitting link located at the same substation. The mimic signal is then subtracted from the interference signal to neutralize the effect of the latter. When both a baseband digital communication system and a carrier communication system utilize the same electrical power lines, provision is made for interrupting the baseband digital signal to allow communications via the carrier system.

Title: Electric generator for a motor vehicle.
IPC: H02K9/06
Filed: 1984-02-14
Abstract: To limit the maximum speed of the fan blade of an automotive-type alternator, the fan blade (21) is secured to the outer race (23) of a ball bearing (22) having a two-part inner race (24, 25), one of the parts being an axially slidable sleeve (25) which is spring-pressed by a cup spring (26) in engagement with a drive pulley (18) against the first race (24). Until a certain limiting reactive pneumatic force or frictional force is reached, the cup spring (26) will clamp the balls (22) between the inner and outer races, so that the fan blade (21) will rotate with the pulley when the reactive force and speed are exceeded, however, the fan blade can rotate about the balls (22), and hence slip with respect to the rotation of the pulley (18).
