Patent ES-358243-A1 (ES)
Title: Moulding Ferro-Cement Pipes
IPC: B28B21/56
Filed: 1968-09-17
Abstract: A reinforced concrete pipe is cast by applying mesh reinforcement about a vertical core 2 which is provided with a detachably secured annular piston 3 at the lower end thereof which is a sliding fit within a vertical mould shell 4. The piston 3 is initially located within the upper end of the shell 4, and either the shell 4 is upwardly displaced or the core 2 is downwardly displaced as the apparatus is simultaneously vibrated, e.g. by means 8, as concrete from a hopper 6, detachably secured to the shell 4, fills the increasing volume of the mould space. After moulding is completed, the piston 3 is detached from core 2, and the hopper 6 is replaced by a ring which restrains the pipe during removal of the core 2, prior to ejection of the pipe from the shell 4.

Title: Apparatus for producing an ion beam by removing electrons from a plasma
IPC: H01J49/16
Filed: 1969-05-14
Abstract: In apparatus for producing a beam of ions a plasma is generated from a target 15 and then subjected to a number of successive electric fields generated by electrodes 26, 32, 34 and 36 which sort out the particles in the plasma and slow down and collect the electrons, and the ionenriched beam is caused to converge towards the aperture in the acceleration or definition plate 36. The target 15 is formed at the base of an equipotential plasma expansion cylinder 24 and is maintained at a more positive potential than the remainder of the electrodes in the coaxial system the electrodes 26 and 32 having successively lower potentials, the concentration electrode 34 having a slightly higher potential than the pre-acceleration plate 32 and the definition plate 36 being grounded. As shown the plasma is generated from the target by a laser beam 48 which is directed on to the target by a silvered mirror 50 and a grated window 54 in the cylinder 24. Alternatively the plasma may be generated by ion bombardment, sputtering or by high frequency discharge. A rack-andpinion arrangement may enable the target position to be varied. Specific dimensions and operating potentials are given in an example in which the source is incorporated in a mass spectrograph system, Fig. 3 (not shown) which comprises a ruby laser, the ion source described, a magnetic deflection arrangement and an ion collection and photographic recording device.

Title: Gas-liquid separator
IPC: G21C15/16
Filed: 1969-11-05
Abstract: A gas-liquid separator for use as a steam water separator in a nuclear reactor steam generator (see Division G6) comprises an elongated vortex tube 36, Fig. 2, having a gas-liquid mixture inlet 31 at one end and an outlet at the other end a vortex generator 32 adjacent the inlet 31 for receiving a gasliquid mixture and for establishing in the tube 32 a gas vortex surrounded by a liquid vortex a liquid discharge channel 38 surrounding the vortex tube a tubular pick-off ring 42 and an annular cover 41 adjacent the outlet of the vortex tube for directing the liquid vortex into the discharge channel 38 and a number of longitudinal, vanes 43 positioned in the discharge channel 38 for arresting the vortex flow of the liquid, the vanes having axially directed leading ends. An annular flow-restriction ring 44 is provided in the channel 38 to maintain a minimum thickness of the liquid vortex in the tube 36. The gas vortex passes through a tube 37 into a dryer 23 comprising a tube 55 against which liquid carried by the gas is separated out and directed by a pickoff ring 57 and an annular flange 58 to a channel defined between the tube 55 and a surrounding tube 59. A gas-liquid mixture from the boundary between the steam and water vortices in the tube 36 flows between the pick-off ring 42 and the tube 37 and is directed by an annular cover 48 into an outer channel 46 within which are arranged vertical chambers 49 and baffles 51, Fig. 4. Assuming a counterclockwise rotation of the mixture entering the channel 46, each chamber 49 is formed of a front member 52, a perforated rear member 53 and a top member 54. The mixture first encounters the front members 52 and the baffles 51 which arrest its rotation and turn the mixture downwards as shown by the solid arrows. The resulting centrifugal force causes the gas to flow, as shown by the dashed arrows, through the perforations in the members 53 into the chambers 49 and out through exit openings 56 formed in the outer tube 47, while the water flows downwards.

Title: Improvements in or relating to diaphragm pumps
IPC: F02M1/00
Filed: 1970-01-10
Abstract: In a diaphragm pump comprising a pumping diaphragm 12 and suction and delivery chambers 14 and 19, the delivery volume and pressure is regulated by an orifice 18 between the chambers which is controlled by a diaphragm 25. Liquid is passed from the suction chamber 14 to the delivery chamber 19, through valves 15 and 20, on reciprocation of the diaphragm 12 by lever 4 and spring 9, and thence to the outlet pipe 33 via valve 23. Diaphragm 25 is pressed by a spring 27 against the orifice 18, such that at an excess delivery pressure the diaphragm is displaced and allows fuel to be spilled back into the chamber 14 vapourization of liquid in the delivery chamber or spout has a similar effect. Increase in pressure in the suction chamber due to vapourization therein is overcome by using a diaphragm spring 9 which will be unaffected by the pressure increase. In another embodiment Fig. 2 (not shown) valve 23 is replaced by a ball valve and the orifice is controlled by a peg carried by a spring-loaded control diaphragm one arm of a two armed pivotally mounted lever, whose other arm is connected to the control diaphragm, acts to close the ball-valve when the recycle orifice is opened.

Patent ES-442373-A1 (ES)
Title: Controller assembly
IPC: B62D5/097
Filed: 1975-11-05
Abstract: An improved controller assembly is utilized in a hydrostatic steering system having an engine driven pump with a servomotor which is effective to vary the displacement of the pump upon operation of a pressure responsive valve assembly. The controller assembly includes a housing having a valve chamber with an inlet port which receives fluid from the pump. Upon rotation of a steering wheel, a controller valve member is moved to an actuated position and a metered flow of fluid is conducted from the valve chamber through a motor port to a steering motor. In addition, fluid is conducted from the steering motor through another motor port to the controller valve chamber. The fluid from the steering motor is then discharged from the valve chamber to reservoir or drain through an outlet port. The controller assembly also includes a control port connected in fluid communication with the pressure-responsive valve assembly. Surfaces on the controller valve member and housing cooperate to form an orifice which causes the fluid pressure conducted to the control port to vary as a function of variations in the rate at which the steering wheel is rotated, and in addition to the pressure required to overcome any variable steered load.

Patent ES-464591-A1 (ES)
Title: Data processing apparatus
IPC: G06F9/48
Filed: 1977-11-30
Abstract: In a multi-programmable data processing system, devices and measures are provided for checking, after execution of a program called up by an interrupt, whether in the meantime another interrupt request of the same type (for example input/output interrupt) has occurred so that the latter can then be served during the interrupt program which is still active. In this manner, the execution of interrupt routines of the same type can be concatenated with one another which saves data exchange processes between processor and memory which otherwise are required at the beginning and end of each interrupt. For the data processing system, a special command "interrogation for waiting interrupt request" (TPI) is provided which can be placed at the end of each interrupt routine and when this is decoded, the interrogation for waiting interrupt requests, the setting of a conditional code and the storing of an interrupt code and a branch back in the relevant program for dealing with the interrupt request found are effected via special signal lines.
