Patent ES-322756-A1 (ES)
Title: Apparatus for forming a beaded shell
IPC: B65D8/12
Filed: 1966-02-08
Abstract: A method of corrugating a hollow metal body of circular, elliptical or polygonal cross-section comprises forming corrugations by means of parallel rings of internal die-segments which are moved axially as they are expanded. Axial tension, produced by expanding the corrugations, may be used to move the dies axially, or (Fig. 1) they may be moved axially by the expanding forces applied, through a rod 49, by an hydraulic cylinder. The die segments (36), Fig. 9 (not shown), are held, by garter &c. springs 41, in tapered pockets 39, Fig. 3, in the opposed faces of rings 38a-38g which are carried by flanged sleeves 44 slidable on a support 31 fixed to a carrier 22. Rubber &c. O-rings 42 form the work-engaging surfaces of the die-rings, and bearing liners 40 are bonded to the segments 36 or the pockets 39. Axial movement of an end-plate 48 moves the rings 38b-38g axially and cams the segments 36 outwardly until the rings are in contact with each other. One or more of the die-rings may be made inoperative, Fig. 8 (not shown), by replacing two or more die-segments of the selected rings with others having tails (56) which extend inwardly and thus prevent relative axial movement between the cam-rings (38b, 38c, 38e, 38f) on each side of the diesegments.

Title: Hydraulically steering devices for vehicles
IPC: B62D5/09
Filed: 1967-08-07
Abstract: An hydraulic steering system for vehicles comprises a rotary-vane master pump A e.g. as described in Specification 1,190,768, connected to a slave cylinder L (whose piston is connected to steering linkage) via a control valve comprising a bored piston M, which is spring- urged to a central position, wherein a fixeddisplacement power-assistance pump X freely supplies liquid via ports R, Q, Q 1 and line T to the tank J, but which is moved (thus closing ports Q or Q 1 ) by the pressure created by the pump A in chamber C or E so as to deliver the pressure liquid from the pump X via port R, bore Z, non-return valves CC or EE and chamber C or E to the lower pressure side of the master pump A to assist the torque applied thereto by the steering wheel B (or its equivalent) and 80 as to disconnect the lower pressure side of the slave cylinder L from the pump A (by blocking bore D 1 or F 1 ) and connect it via ports D or F and Q or Q 1 to the tank J. Thus the pressure difference in the slave cylinder L is equal to the sum of the manually produced pressure in master pump A and the pressure supplied by the pump X to the lower-pressure side of the master pump A. The vehicle steers itself when being towed. Failure of the pump X or its delivery line does not interfere with manual operation of the system. In Fig. 2, a single pre-loaded spring N 2 urges the piston M to a central position, and each vane A 1 of the master pump A is urged by a spring A 2 against its housing.

Title: Thyristor control circuit with full load current by-pass,particularly for electrical vehicles
IPC: H02P7/29
Filed: 1967-12-21
Abstract: A control system for a d.c. motor 10, 11, e.g. for traction comprises a semi-conductor switch (thyristor 13) for regulating the current, a control circuit 37 responsive to a reference value set on a controller 42, and a bridging contactor 19, 22 shunting the switch and controlled by a voltage dependent semi-conductor (transistor) circuit 67 connected through an integrating circuit to the output of the control circuit 37. The reference value at 42 is opposed by the voltage across a resistor 18 in series with the motor, smoothed by capacitor 64, so that the circuit 37 controls the duty ratio of thyristor 13 to keep the motor current constant, at leat during acceleration. When, as the motor nears full speed, the duty ratio approaches 100% the voltage from the integrating circuit (in 67) is sufficient to switch on the transistor circuit 67, thereby energizing 19 and closing contacts 22. Thus the motor is fully energized, but the circuit 37 continues to be activated and if, due to an increased load, the duty cycle drops, the bridging contactor is deenergized and current control re-established. The bridging contact is, however, held closed if the controller 42 is advanced to the full speed position, and also if a second integrating circuit detects very rapid switching by the circuit 37, which occurs if the motor is stalled. Rapid changes by the controller 42 in the increase current direction are delayed by RC circuit 53, 63, which is short circuited for the decrease direction by a diode 62. Motor current during "off" periods is carried by a freewheeling diode 33. The main thyristor 13 is switched off by a capacitor 26 switched by a commutating thyristor 25, 13 and 25 being triggered alternately by respective blocking oscillators 35, 36 controlled by the circuit 37. The triggering circuits 35, 36 and the control circuits 37, 67 are fully described Figs. 6 and 7 (not shown). The thyristor 13 may alternatively be a "gate controlled switch". A resistor 59 is inserted in the current feedback path when 22 is closed to compensate for the current change due to loss of voltage drops though 13.

Patent ES-440248-A1 (ES)
Title: Choke control system for internal combustion engine
IPC: F02M1/00
Filed: 1975-08-14
Abstract: A first choke valve is mounted in a main intake passage carrying a lean mixture to a main combustion chamber, and a second choke valve is mounted in an auxiliary intake passage carrying a rich mixture to a relatively small auxiliary chamber. Spark ignition of the mixture in the auxiliary combustion chamber projects a flame through a torch nozzle connecting the chambers to ignite the lean mixture in the main combustion chamber. Control of the main choke valve for moderately cold starting or extremely cold starting is accomplished automatically by means of a control element driven by a heat responsive bimetal element, or by means of a manually operated control element. In either case, overtravel of the control element after the main choke valve closes stores energy in a spring to increase closing torque of the main choke valve, and also moves the auxiliary choke valve toward closed position, to improve engine startability under extremely cold conditions. Both choke valves open in response to complete firing of the engine.
Patent ES-451401-A1 (ES)
Title: Continuous extrusion
IPC: B21C23/04
Filed: 1976-09-19
Abstract: Four trains of gripping element quadrants are advanced continuously around four endless paths, meeting along one length of travel common to the four paths and cooperating to form a succession of centrally apertured gripping elements moving continuously toward an extrusion die located along the common length of travel. The gripping element quadrants are driven by pinion gears, each of which engages simultaneously sets of teeth on gripping element quadrants in two adjacent trains in order to key the quadrants together and thereby prevent one quadrant from lagging another during their advance toward the die. Four guide elements extend along the paths of the gripping elements and engage simultaneously portions of the two adjacent gripping element quadrants to guide the engaged quadrants during their advance toward the die. Four endless belts are advanced with the gripping elements toward the die and serve to transmit pressure from four stationary pressure pads to the moving gripping elements. Rod of indefinite length, coated with a shear transmitting medium and extending into the central apertures of the gripping elements, is drawn along the common length of travel by means of shear forces generated in the coating by the gripping elements and transmitted to the rod as viscous drag force along the surface of the rod. Axial and normal stresses are built up in the rod to stress the rod far above its yield strength and increase its ductility, or capacity for deformation without fracture. In this state, the rod is moved through and deformed by the die.

Patent ES-478368-A1 (ES)
Title: Valve assembly.
IPC: F16K11/04
Filed: 1979-02-20
Abstract: A valve assembly of the type providing bypass flow through a branch channel when the movable valve member is in the closed position to block flow through the main flow channel outlet. A venturi device is disposed in the main channel upstream of the movable valve member, and the venturi has secondary ports provided through the wall at the throat section. When the movable valve member is in the closed position, flow into the venturi exits at the flow ports and flows through the bypass channel. When the movable valve member is in the open position, flow discharges from the venturi, through the main channel outlet port downstream of the movable valve member, thereby causing reduced pressure at the venturi throat and preventing flow through the secondary ports to the bypass channel.
