Patent ES-405605-A1 (ES)
Title: Tools and machine parts and methods from inverse draft forging
IPC: B21K5/00
Filed: 1972-08-05
Abstract: The disclosure is directed to the use of forging tools and machine parts by employing a method and structure in the form of a negative draft angle and larger positive draft angle to form tongue or groove elements in the tools and machine parts as forged from the dies. Employment of the negative draft angle with a greater positive draft angle permits tools and machine parts to be formed so that the metal being worked is formed with a continuous uncut and uninterrupted grain flow extending longitudinally of the working member being formed. A negative draft angle of substantially 5 degrees when used with a positive draft of substantially more than 5 degrees has been found to produce excellent results.

Patent ES-449712-A1 (ES)
Title: Turbocharger lubrication and exhaust system
IPC: F02B39/14
Filed: 1976-07-09
Abstract: A turbocharger system. One impeller of the turbocharger is driven by exhaust gas from an internal combustion engine, the other impeller functions as a pump to either compress air or to pump air in order to convey granular material. The impeller wheels are spaced and are mounted at the ends of a common shaft. The shaft is continuously lubricated, the spent lubricant being fed to an oil sump (crankcase). The specific improvement is a pressure bleed passageway between the chamber which receives engine exhaust pressure and the oil exhaust line. The bleed allows a portion of engine exhaust to pass to the sump exhaust line and assist oil flow to the sump by virtue of a pressure differential. This action, in turn, inhibits spent oil from passing through the seals and passing into either or both impellers when oil sump (crankcase) pressure is higher than atmospheric or where there are unfavorable to gravity flow conditions existing in the oil return line. Another portion of the system bleeds air from a high pressure reservoir to the interior of the oil sump line to assist spent oil flow to the sump.

Patent ES-470259-A1 (ES)
Title: Drum-type screening machine
IPC: B07B1/20
Filed: 1978-05-27
Abstract: A drum type screening machine has a centrifuging rotor within it. A perforated retaining element is carried by the shaft between a feed inlet and an entry region of the drum. The perforations of the retaining element are small enough to retain the foreign bodies which it is intended to retain but larger than the perforations of the screen. The retaining element has an access aperture, a closure element and means for holding the closure element movably in position to close the aperture. The retaining element can be a basket made up of a perforate plate with a perforate rearward flange. The closure element can be a half-moon segment, located by locating pins and rotatable on the shaft with respect to the remainder of the retaining element on clearing the locating means when pressed axially against the force of a bias spring. Use of the retaining element prolongs the screen life so much that tension adjustment become necessary. Provision is made for this to be done from outside of the machine. The screening drum has a pair of rings which support the screening cloth and which are held apart at an adjustable distance by tensioning bars. One ring is supported within an end member of the machine housing and the other on support means within the housing. Each bar is externally threaded, e.g. by way of an extension sleeve that is axially fast with the bar. The sleeve is engaged by an internally threaded nut which is axially fast with the end member of the machine. The sleeve extends through that nut and through the end member to the outside of the machine. A hexagonal head formed on the end of the sleeve can be turned exteriorly of the machine with a box spanner, thereby to tension the screen cloth.

Patent ES-488362-A1 (ES)
Title: Toy dolls and figurines having surface portions of reversibly changeable color
IPC: A63H3/00
Filed: 1980-01-29
Abstract: Toy figurines including toy dolls are disclosed that have skins or exterior surfaces repeatedly capable of reversibly changing color. The skin is coated with a sealant/primer base coat of flexible, hydrophobic film-forming polymeric material. Applied over the base coat is a color layer which is either continuous or of desired geometric configuration. The color layer contains acid-base indicating material, preferably microencapsulated, matrixed in a mixture of polymeric material. A top coat applied over the color layer protects the color layer against abrasion and is water permeable. The coated skin portions thus change color in response to changes in the pH of aqueous solutions applied to them.

Patent ES-8206926-A1 (ES)
Title: Electrical machine having a stator core of grain-oriented laminations.
IPC: H02K19/22
Filed: 1981-02-13
Abstract: The laminations of a laminated stator of a slowly running electrical machine having a high number of poles are composed of grain-oriented sheets, each of which has a preferential magnetic direction that extends substantially longitudinally along the teeth of that sheet. This permits the excitation current to be reduced, and, as a result, the air gap of the machine can be enlarged so that, on the whole, approximately the same excitation is required as for a laminated stator in which the laminations consist of normal, non-oriented sheets. As a result, the mechanical stability of the machine is increased. The invention is especially useful in asynchronous tube generators.
