Title: Fe-Cr-Co magnetic alloy processing
IPC: C22C38/00
Filed: 1979-07-12
Abstract: A method is disclosed for making a metallic body having desirable magnetic properties. The metallic body is made from an alloy which contains Fe, Cr, and Co and which may also contain one or several additional ferrite forming elements such as, e.g., Zr, Mo, V, Nb, Ta, Ti, Al, Si, or W. According to the disclosed method the alloy is cooled at a rate of at least 60 degrees C. per hour from an initial temperature at which the alloy is in an essentially single phase alpha state to a second temperature which is in a vicinity of 600 degrees C. Subsequently, the alloy is cooled at a second, slower rate to a third temperature which is in the vicinity of 525 degrees C. The disclosed method allows for a relatively broad range of initial temperatures, is relatively insensitive to compositional variations of the alloy, and permits simple reclamation of suboptimally treated parts. As a consequence, the method is particularly suited for large scale industrial production of permanent magnets as may be used, e.g., in relays, ringers, and electro-acoustic transducers.

Title: Take-off ramps for aircraft
IPC: B64F1/36
Filed: 1980-09-26
Abstract: An aircraft take-off ramp, for causing an aircraft with a compressible, shock absorbing and damping landing gear to be so urged from a horizontal path that it follows an initially ballistic trajectory on leaving the ramp, has its profile derived from a notional generally circular arc. The notional arc has its radius selected so that the center of gravity of the aircraft, if its landing gear was incompressible, would follow a desired locus. The derived profile is so modified from the notional arc that during traverse of the ramp the compressible landing gear is compressed so that the center of gravity of the aircraft follows the desired locus.

Title: Tape recording or reproducing apparatus with a pinch-roller mounted on a pivotable arm.
IPC: G11B15/29
Filed: 1980-12-19
Abstract: A capstan drive tape recorder having a pressure roller on an arm which is pivotable to hold the tape against the capstan. To move the arm between the operating and a rest position, the arm is connected by a spring to a lever, the arm and lever being pivotable about the same axis. An actuating device moves the lever to bring the pressure roller into engagement with a tape against the capstan. In moving the arm, the lever is first pivoted about one axis, and then about a second axis so that the mechanical advantage of the lever is changed between a ratio which moves the roller a considerable distance, and a ratio which biases the roller against the capstan.

Patent ES-8303866-A1 (ES)
Title: Dual mode horizontal deflection circuit
IPC: H04N3/16
Filed: 1982-02-04
Abstract: A horizontal deflection turn-on circuit operates in the absence of trigger pulse normally derived by an AFPC loop. Under normal operation, the AFPC loop generates the trigger pulses based on a synchronized phase relationship with sampled flyback pulses. During receiver start-up, the flyback pulses are not present and no trigger pulses are generated. The turn on circuit provides auxiliary pulses which occur later in time than the normal occurrence of the trigger pulses. Means are provided for applying the auxiliary pulses to the horizontal deflection circuit only in the absence of normal trigger pulses.

Patent ES-8400565-A1 (ES)
Title: Jack for crown or disk brakes
IPC: F16D65/18
Filed: 1983-01-11
Abstract: A first piston having a passageway for hydraulic fluid and a second piston slide within a cylindrical body of a jack for crown or disk brakes provided with a spring for opening the brake clamp or yoke. An extension of the first piston slides within a guide and actuates a movable pusher. A closure seal closes the passageway when the first piston touches the second piston. The axial friction force of the second piston on the cylindrical body is more than the force of the spring. The axial friction force of the second piston on the cylindrical body is more than the sum of the axial friction force of the first piston on the cylindrical body and the axial friction force of the extension on its guide, whereby the axial displacement of the first piston occurs before the axial displacement of the second piston when said pistons are actuated by same pressure. The displacement of the second piston takes up the wear of the brake linings while the displacement of the first piston effects the clamping of the brake linings on the crown or disk.
Patent ES-8502276-A1 (ES)
Title: Fuel flux having enrichment devided axially
IPC: G21C3/32
Filed: 1983-02-23
Abstract: A configuration of a nuclear fuel cluster (15) which permits the clearance for the cold, shutdown state to be preserved with minimum impairment of the operational efficiency. The cluster has a component which is made from fissile material and which is distributed over a substantial axial extent of the nuclear fuel cluster, the fuel having a relatively reduced enrichment in an axial zone (62) (the "zone of reduced enrichment") in an upper region, this zone corresponding at least partially to a section of the axial region in which the reactivity has a maximum in the cold shutdown state. The nuclear fuel cluster normally comprises a first subgroup of nuclear fuel rods (1) having a reduced enrichment in the zone of reduced enrichment as well as a second subgroup of nuclear fuel rods (2 to 8) having a uniform enrichment along its axial dimension. In order for the number of nuclear fuel rods which have to be characterised by an enrichment that is not axially uniform to be kept as low as possible, it is preferred for the first subgroup (1) to contain one of the rods having the highest enrichment of the nuclear fuel cluster. The resulting somewhat higher axial power peak towards the lower part of the nuclear fuel cluster can be compensated by arranging more burnable absorbers in a corresponding lower zone (67). A middle zone (70) is characterised by a higher enrichment and a lower gadolinium content, which leads to the section of the core having the highest reactivity.
