Patent ES-8406911-A1 (ES)
Title: Punching tool made of strip-like steel
IPC: B21D28/14
Filed: 1982-07-19
Abstract: The invention relates to a strip steel punching tool with at least one strip-shaped punching blade (3) which has a cutting edge (6), which is held in a slot (4) of a blade carrier (5) and the rear end of which, lying opposite the cutting edge (6), is supported via its bearing surface on a metal plate (1) harder than the rear end of the blade, at least the cutting edge (6) of the punching blade (3) being hardened. To achieve an accurate cut which is equal over the entire length of the punching blade (3), the bearing surface of the rear end of the blade is reduced in order in this way to form a deformation zone in the reduced bearing surface. The deformation resistance of the material of the punching blade is then lower, at least in the region of the bearing surface, than in the region of the cutting edge (6). Self-regulating cutting-blade alignment is thereby achieved since, in the case of excessively high local cutting forces, deformation of the overloaded reduced bearing surface takes place until the cutting force is distributed uniformly over the entire length of the cutting blade (6). Time-consuming alignment and setting work is thereby eliminated.

Title: A storage subsystem with hashed cache addressing.
IPC: G06F17/30
Filed: 1982-08-16
Abstract: A storage subsystem including a cache (12) and backing storage (11) pairing is set associative under a hashing protocol which efficiently accommodates discontinuities in the backing storage (cylinder boundaries in a disk device) and preferential modules (index cylinders in multiple disk devices). The hashing preserves sequentiality between discontinuities and, by selective offsetting, ensures no hash overlap between preferred modules. The cache directory (30) comprises linked lists accessed by list from a table (27) accessed by the hash mechanism (34) which can be bypassed by reference to stored previous hash transforms (at 34) or by arithmetic determination.
Patent ES-8400535-A1 (ES)
Title: A bypass system for a steam turbine
IPC: F01K7/24
Filed: 1982-09-21
Abstract: A bypass system for a steam turbine wherein the temperature of the steam bypassed around the high pressure turbine (12) is accurately controlled by measuring the inlet and outlet temperatures of the boiler reheater (32) and generating an adaptive set point. The set point value is used to govern operation of a spray valve (84) which admits cooling water to the bypass steam path (74). The bypass system also includes, a throttle pressure control (150) wherein the outlet throttle pressure of the boiler is controlled by controlling admission of steam into the bypass path (74) by means of a bypass valve (72) independently of steam flow during turbine start-up. When the turbine (10) is fully operational the throttle pressure control is effected by a comparison of the actual throttle pressure with the desired throttle pressure set point plus some bias.
Patent ES-8403959-A1 (ES)
Title: Method for the recovery of fuel from oil shale.
IPC: C10G1/00
Filed: 1982-10-18
Abstract: Raw shale is supplied to a pyrolyzer where it is pyrolyzed by fuel gas and hot spent shale derived from a gasifier. Typically, the raw shale is Eastern U.S. shale and the pyrolyzer includes a fluidized bed. The pyrolyzed shale having given up its oil and volatile hydrocarbons, rises to the top of the fluidized bed of raw shale where it is transferred to the gasifier. Oxygen and steam are supplied to the gasifier. This composite gas reacts with the carbon of the pyrolyzed shale in a fluidized bed to produce synthesis or fuel gas. The oxygen is supplied in such quantities as not to react completely with the carbon in the pyrolyzed shale. The steam reacts with the excess of carbon. Predominantly hydrogen and carbon monoxide are produced in addition there is a smaller quantity of carbon dioxide and methane. This hot fuel gas is transferred to the pyrolyzer. In addition, hot spent shale is transferred to the pyrolyzer. The hot fuel gas fluidizes the raw shale in the pyrolyzer. The hot gas and the hot spent shale heat the raw shale separating the shale oil and product gas including volatile hydrocarbons. The oil is condensed and collected, the fuel gas is collected for utilization in the above process and also for other purposes.
