Patent ES-418943-A1 (ES)
Title: Multi-load tractor hitch system
IPC: A01B59/043
Filed: 1973-09-20
Abstract: A tractor includes a hitch system comprising spaced lower draft links carrying draft hooks at their distal ends and an upper center link in the form of an extensible and retractable hydraulic actuator and a drawbar. An inverted U-shaped arch member has opposite legs respectively pivotally connected to the draft links at locations intermediate the ends thereof by means establishing a horizontal transverse axis about which the arch member is swingable fore and aft. A swivel bracket including rollers is mounted for rolling movement along the transverse bight portion of the arch member between a stored position on one of the legs of the arch member and an operative position on the transverse bight portion of the arch member. The hitch structure may be arranged in a three-point hitch mode by suspending the center link-forming hydraulic actuator from the bight portion of the arch member by spring means and by connecting a draft hook to the end of the piston rod of the center link-forming actuator. The hitch structure may be arranged in a weight transfer mode by placing the swivel bracket in its operative position, by connecting the end of the piston rod of the center link-forming actuator to the bracket and by connecting a force transmitting member or link between the swivel bracket and the implement to be towed. The hitch structure includes draft responsive means for initiating automatic draft and weight transfer control, the draft responsive means being, in one embodiment, responsive to forces imposed on the lower draft links or on the drawbar and being responsive in a second embodiment to draft forces imposed on the center link-forming actuator.
Patent ES-424286-A1 (ES)
Title: Procedure for making tests of propeller cavitation
IPC: B63B71/20
Filed: 1974-03-14
Abstract: A technique for testing marine propellers by analyzing the type of cavitation appearing on a reduced-scale model of the associated actual ship, and thereby obtaining data for correcting imperfections in propeller design, and for reducing pressure fluctuations at the lower sternframe portion of the ship. The technique inculdes simulating the water flow acting on the propeller. The procedure is characterized by adjusting the denominator of the cavitation index of the model in order to achieve an approach in the tests to equality between the cavitation indices of the model and the actual ship. This adjustment is achieved in the tests by increasing the towing speed or the propeller revolution rate of the model until the above-mentioned equality of cavitation indices is reached, ignoring the influence that the actual component of the wake speed due to wave formation might have in the tests. The procedure includes consideration of the increase in pressure of the propeller disc points due to the increased draught caused by the wave formation, and establishing a water line for the model corresponding to the loading condition to be tested, by the use of a steel sheet, or the like, on the hull of the model of adequate thickness and dimensions. The procedure enables tests to be conducted in conventional ship model basins without requiring vacuum, or in open water with the model in the loading condition desired, either floating on the surface or, made watertight and being totally submerged, taking into consideration the immersion of the model when the numerator of the above-mentioned cavitation index is calculated, and the tests being conducted at the speed for which the cavitation indices of the model and actual ship are equalized, the dimensional thrust coefficient KT of the model being identical to that of the actual ship.

Patent ES-462617-A1 (ES)
Title: Mixing and distributing apparatus for gasoline and oil
IPC: B67D7/74
Filed: 1977-09-24
Abstract: A mixing and distributing device for gasoline and oil comprises an oil inlet, a duct for gasoline under pressure and a delivery duct. A first vertical cylinder having a first piston is fed from the top with oil and gasoline through a slide valve. A second vertical cylinder, which is located inside the first cylinder and under the first piston, has a second oil piston sliding therein. When the valve is in a first position, gasoline under pressure is fed to the first cylinder thereby urging the first piston downward against a biasing spring to move the second piston downward through abutments on the interior of the first piston. This causes a metered supply of oil to be fed to the top of the first cylinder so as to mix with the pressurized gasoline. A second position of the valve terminates the supply of oil and gasoline, and allows the mixture to be expelled by the first cylinder piston under the effect of the biasing spring through the valve and the delivery duct.

Patent ES-8202760-A1 (ES)
Title: Elevator group control.
IPC: B66B1/18
Filed: 1980-12-20
Abstract: With this group control the allocation of elevator cabins or cars to existing storey or floor calls should be timewise optimized and newly arriving storey calls should be immediately allocated. A computer device provided for each elevator computates at each landing or storey, irrespective of whether or not there is present a storey or landing call, from the distance between the storey and the cabin position indicated by a selector, the intermediate cabin stops to be expected within this distance and the momentary cabin load a sum proportional to the time losses of waiting passengers. In this way the cabin load prevailing at the computation time point is corrected such that the expected number of passengers entering and exiting the cabin, derived from the previously ascertained number of entering and exiting passengers is taken into account for the future intermediate cabin stops. Such loss time sum, also referred to as the servicing cost, is stored in a cost storage or memory provided for each elevator. During a cost comparison cycle the servicing costs of all elevators are compared with one another by means of a comparator, and in an allocation storage of the elevator with the lowest servicing cost there can be stored an allocation instruction which designates that storey or floor to which there can be optimumly allocated the relevant elevator cabin.
