Patent ES-346712-A1 (ES)
Title: Liquid fuel pumping apparatus
IPC: F02M41/14
Filed: 1967-10-21
Abstract: In a radial cylinder rotary distributer type fuel injection pump inward movement of the pistons 13 causes liquid to move a valve 21 to the right against the action of a spring 22 and so cause displacement of liquid from the spring chamber to an outlet port 19 which at this time is in alignment with one of the outlet passages 20. Further movement of the valve connects the pump cylinder through longitudinal and cross bores in the valve to the spring chamber and outlet port 19. The end of the discharge stroke is followed by a slight retraction of the pistons 13 so that the valve 21 moves to the left relieving the pressure in the outlet passages this period of retraction is followed by a dwell during which the cylinder and valve bore are connected both to the inlet port 26 leading through a governor controlled throttle to the outlet of the feed pump, and to a drain passage 30 at low pressure. The drain passage then closes followed by closure of the delivery passage 20 and outward movement of the pistons 13. The pressure in the spring chamber and outlet port 19 is then adjusted by one of the ports 32 which comes into communication with a port 33 leading to the feed pump outlet passage 15. The delivery in relation to speed is adjusted by means of a spring loaded piston 41 in a chamber 40 which is brought into communication with the spring chamber and outlet port 19 by means of a port 46 with which one of the ports 32 communicates when outlet port 19 connects with an outlet passage 20. Movement of the piston 41 is limited by a stop, the position of which is adjusted in accordance with feed pump outlet pressure which is speed sensitive. Subsequently the chamber 41 returns liquid to the spring chamber through a port 46. The pump cam ring may be angularly-adjustable to vary timing.

Patent ES-347974-A1 (ES)
Title: Nuclear fuel assembly
IPC: G21C3/322
Filed: 1967-12-05
Abstract: A nuclear fuel assembly comprises at least one bundle of fuel pins provided with expansion chambers and disposed in a coolant circulation duct, a tubular support located along the axis of the duct, and top and bottom end fittings respectively connecting the upper and lower ends of the duct and support, the latter supporting the fuel pins and defining an axial passageway which by-passes the space between the expansion chambers. The assembly for use in a fast reactor, shown in Figs. 1 and 2, comprises a central bundle 10 of pins loaded with fissile material disposed between a top bundle 12 and a bottom bundle 14 of pins loaded either with fertile material or with neutron-absorbing material. A tube 16 is secured at its lower end to a bottom end fitting 18 provided with coolant inlets 20 and an annular plate 22 is secured around the top of the tube 16. The pins of the central bundle 10 are of smaller diameter than those of the top and bottom bundles 12, 14 and are supported on rails secured to a grid 35. In order to permit of their free expansion, the upper ends of these pins are simply guided by another set of rails secured to a grid 34. The grids 34, 35 are provided with openings for the flow of coolant and are secured to the tube 16. The lower half of each fuel pin constitutes an expansion chamber and is separated from the upper fuel-containing half by a neck 36. A thin-walled sleeve 38 which may be formed from a spirally - wound strip surrounds the three bundles 10, 12, 14 and is attached to the bottom end fitting 18 and to the annular plate 22. At the level of the necks 36, the tube 16 contains a series of coolant outlets 44, and immediately above this level it is sealed off by a plug 42. Coolant is admitted through the inlets 20 and the greater part of the flow passes upwardly through the tube 16 and is discharged through the outlets 44, thus by-passing the bottom bundle 14 and that portion of the central bundle 10 comprising the expansion chambers. A fraction of the flow passes out of the duct 16 through ports 46 and enters the bottom bundle 14, cooling the pins of this bundle and the expansion chambers of the pins of the central bundle 10. A collector space 37 formed by the necks 36 permits uniform cooling of the fuelcontaining portion of the bundle 10. The total flow cools this portion and the top bundle 12 before passing out through openings 48 in the annular plate 22.

Patent ES-363283-A1 (ES)
Title: Battery charging systems
IPC: H02P9/48
Filed: 1969-01-29
Abstract: A vehicle battery 11 is charged by a singlephase permanent magnet alternator 12 through a rectifier comprising a pair of diodes and a pair of thyristors. A regulator 16 provides gate current to the thyristors provided that the batteryvoltage is below a predetermined value, and interrupts the rectified output from the alternator for periods which result in stabilized battery voltage. When an ignition switch 13 is closed, capacitor 21 is charged and transistor 19 conducts to ensure that transistor 26 remains off, whereby transistor 29 conducts to illuminate a warning lamp 31. When the alternator is delivering current, it produces substantial ripple voltage across lines 14, 15, to augment the voltage on capacitor 21. The transistor 19 is turned on at the peak of each ripple pulse, and is held off for the rest of the cycle whereby capacitor 24 is charged to enable base current to be supplied to transistor 26. During brief periods of conduction of transistor 19, capacitor 24 discharges to supply base current to the transistor 26. Thus, when there is ripple voltage between lines 14, 15, the transistor 26 conducts and the lamp 31 is off. If the ripple supply is interrupted by the regulator 16, the capacitor 21 discharges to hold the transistor 19 off so that the lamp remains off. If the ripple voltage is absent for a substantial length of time, however, the capacitor 21 discharges completely whereby transistor 19 conducts to illuminate the lamp. When the voltage across lines 14, 15 exceeds a predetermined value, zener diode 33 conducts to turn on the transistor 29 and illuminate the lamp.

Title: Valve devices for pressurized containers
IPC: F17C5/02
Filed: 1969-12-17
Abstract: A valve device mounted in an opening provided in the wall of a pressurized container comprises an outer cup-shaped member made of a resilient plastic and an inner cup-shaped member made of a rigid material and mounted as a force fit in the outer cup-shaped member. The outer cup-shaped member has a perforated bottom which carries an upwardly extending axial portion adapted to form the closure member of the device. Under the action of the resiliency of the outer cup-shaped member this closure member is engaged in gas-tight contact into a tubular seat portion carried by the bottom of the inner cup-shaped member. This seat portion has a perforatable upper wall adapted to be perforated by the needle of a gas-intake head. The needle depresses the closure member and thus opens the valve device. If the gas-intake head is accidentally removed, the closure member returns to the closed position and prevents any gas exhaust from the container.
