Patent ES-396312-A1 (ES)
Title: Vacuum skin package, and process and apparatus for making same
IPC: B65B31/02
Filed: 1971-10-23
Abstract: In the prior art, vacuum skin packaging processes are performed by placing the product to be packaged on an impervious backing board placing the product and board in a vacuum chamber positioning a sheet of thermoplastic film above the product and backing board in the chamber evacuating the chamber then, either pulling the film down over the product or pushing the product up into the film and, thereafter sealing the film to the board. In the present invention, a portion of the film is drawn by differential air pressure against the concave interior surface of the upper portion of a vacuum chamber the film is then heated by surface contact and then, after evacuation of the chamber, air pressure is used to blow the film down over the product and against the backing board. Thus, in the present invention, the film is shaped in a concave fashion surrounding the upper portion of the product and it is not necessary for the product to move. The height of the chamber may be adjusted for different products so that excess film is not used and wrinkling is prevented.

Title: Process for the manufacture of artificial leather and product made thereby
IPC: D06N3/10
Filed: 1972-03-30
Abstract: A process for the manufacture of artificial leather which has a napped, suede or nubuck surface finish by contacting a natural, synthetic of semi-synthetic backing member with a polymeric system comprising a mixture of a heat-reactive latex and a carboxylated latex and which contains at least one dyestuff. Each of the latices is cross-linked in sequence while the contacted backing member is dried. The migration of non-polymeric components in the system of latices is suppressed during drying. The backing so treated is mechanically altered on the grain side of the backing member to provide an irregular leather-like surface thereto.

Patent ES-403681-A1 (ES)
Title: Method of making a composite heavy duty bushing
IPC: F16C33/14
Filed: 1972-06-09
Abstract: A composite heavy-duty bushing, such as a bearing bushing or bearing race (FIG. 4) consists of a high load-bearing or working portion consisting of a sleeve composed of sintered powdered high-performance alloy and a supporting or mounting sleeve subjected to less concentrated or intense loads made of an inexpensive base metal, such as sintered powdered iron. These two sleeves are separately briquetted, and then assembled telescopically. This assembly is then sintered while the sleeves are thus united, and finally hot-forged in an axial direction. This forging operation densifies the composite assembly from the sintered briquette density of about 75 percent to a final density of about 98 percent and at the same time upsets the ends of the base metal sleeve into an adjacent end bevel in the high performance alloy sleeve, hereby clinching the two sleeves inseparably to one another. Photomicrographs of longitudinal sections of these composite bushings spanning the joint between the two sleeves (FIG. 6) after subsequent carburizing and hardening heat treatment show a superior interlock therebetween resulting from a migration of the metals into one another across the interface therebetween into an intermediate zone of the intermingled metals which encircles the interphase. Torsion tests performed on such sections show adequate strengths without failure along the junction surfaces which compare favorably with the strength of similar single solid metal bushings. These photomicrographs also show that such a complete bond has been achieved along the central or axial portion of the joint, that the beveling of the ends is not essential in order to form a joint of adequate strength. Such beveling at the ends is therefore optional and is provided as an additional means of retention of the inner sleeve inside the outer sleeve.

Title: Hot-rolled high-strength low-alloy steel and process for producing same
IPC: C22C38/12
Filed: 1974-05-21
Abstract: A ferritic hot-rolled high-strength low-alloy steel having a yield strength in excess of 65 ksi and excellent subzero impact properties which contains 0.03 to 0.15% carbon, 0.5 to 2.0% magnanese, 0.1 to 0.40% molybdenum and 0.01 to 0.10% columbium. The steel is strengthened by the combined effects of grain refinement, precipitation hardening and a high dislocation density which are effected by partially hot rolling the steel above the Ar3 transition temperature and then hot rolling to effect a 10 to 40% thickness reduction at intercritical temperatures between the Ar3 and Ar1 transition temperatures. Some embodiments of this steel may be further strengthened by a subcritical temper, or a small amount of cold working.

Title: Lens-grid system for electron tubes
IPC: H01J35/14
Filed: 1975-04-30
Abstract: An electron tube such as an x-ray tube has an anode target spaced from an electron beam emitting structure which include a cathode, focusing electrode and a control electrode. The control electrode surface nearest the anode is contoured to conform with selected equipotential values in the electrostatic field between the cathode and anode which equipotential is a predetermined percentage of the total cathode to anode voltage. When the control electrode is operated at a corresponding positive potential, the electrons follow certain trajectories and focus on the anode. Means are provided for varying the control voltage through a range from beam cut-off voltage to various positive voltages that permit control of the focal spot size regardless of the selected beam current and selected anode voltage.

Title: Desulfurizing a fuel with alkanol-alkali metal hydrosulfide solution
IPC: C10G29/10
Filed: 1980-08-07
Abstract: Petroleum crude and certain liquid distillate fractions derived therefrom, and other sulfur containing fuels or residues are reduced in sulfur content by intimately contacting the fuel or residues with alkanol solutions of alkali metal hydrosulfides, at temperatures and pressures from ambient up to the critical temperature of the alkanol for from 1 to 20 minutes. Thereafter, the fuel is caused to separate from the alkanol solution by the addition of water. A liquid-liquid separation separates desulfurized fuel from the alkanol solution. Hydrogen sulfide formed in the process is used to re-generate alkali metal hydrosulfide for use in desulfurizing additional petroleum fuel.
Patent ES-8107013-A1 (ES)
Title: Speed control circuit for electric motor
IPC: A47L9/28
Filed: 1980-10-03
Abstract: Disclosed is an apparatus for controlling the rotational speed of an electric motor based upon the load encountered by the electric motor. A load sensor provides a voltage level based upon the operating load of the electric motor and accumulates this voltage in accordance with the cycle of the alternating current supplied to the motor. If during a cycle of the alternating current, the voltage exceeds a predetermined level, a transistor will be biassed into conduction, said transistor turning off a thyristor and preventing any further conduction of the thyristor during that cycle of the alternating current. Thus the duty cycle of the thyristor determines the total amount of current supplied to the electric motor and this current level determines the rotational rpm of the motor.
