Patent ES-8103264-A1 (ES)
Title: Rotary piston IC engine - has rectangular pistons pivoted on rotor concentric in stator
IPC: F01C1/44
Filed: 1980-04-02
Abstract: The engine has a stator (1) with an inner profile formed of four arcs, joined by four straight sections. A rotor (8) revolves on an axis through the centre of the stator and carries several pistons (5) on its periphery. Each piston is in the form of a rectangle with rounded corners and pivots on the rotor on an axis parallel to the rotor axis. Two of its edges (6) run on the inside of the stator. The resulting motion produces variable volume working chambers between the pistons and stator. It is equivalent to a trochoidal path, but is achieved with more easily machined components.
Patent ES-8103425-A1 (ES)
Title: Sheeting of multilayer antidrumming lining material
IPC: B32B11/06
Filed: 1980-04-29
Abstract: A sheeting of multilayer antidrumming lining material, viz. a film containing bitumen or plastic, or a combination film containing bitumen and plastic, which is backed with a wide-meshed fabric having a high tensile strength. This high-tensile fabric backing prevents the antidrumming film, on the one hand, from cracking and, on the other, it holds it even when in a plasticized condition on the upper edge of a steeply inclined or vertical sheet metal component, so that the piece of antidrumming film hanging thereon cannot slide off. Also, due to the backing fabric, the film does not flap away outwardly and upwardly in the area where a steep descent starts. Finally, the tensile strength of the plasticized film is increased such that it cannot crack under the influence of gravity in the area of vertical sides. Where strongly localized form fitting adaptation of the sheeting of antidrumming lining material to the shape of a substrate is required, a few areas of the sheeting of antidrumming lining material do not have any backing material. Also cutaway portions which are adapted to the requirements of the curved sheet metal component to be deadened can be provided. Advantageously, the edges of the cutaway portion are also reinforced with extra pieces of a wide-meshed fabric to afford additional protection against deformation.

Title: Control system and method for a steam turbine having a steam bypass arrangement
IPC: F01K7/24
Filed: 1983-07-11
Abstract: A DEH (digital electrohydraulic) control system for a steam turbine generator having a steam bypass system. The turbine system includes a high pressure turbine having throttle and governor steam admission valves as well as an intermediate pressure turbine having stop and interceptor steam admission valves. The turbine is brought on line by initially controlling steam admission into the intermediate pressure turbine by modulating the interceptor valve in response to a speed error signal generated as a result of the difference between actual and a predetermined reference speed. During this initial control the throttle valve remains in a closed position. When the turbine speed has attained a preset value such as half of synchronous speed, the interceptor valve is held at the same position it was in when the preset speed was attained and the throttle valve is controllably open in response to the same speed error signal. After a preset transfer speed has been attained, control of steam admission to the high pressure turbine is transferred to the governor valve and after synchronous speed has been reached the DEH system switches to a load control mode wherein the signal which controls the positioning of the governor valve is also utilized to control the interceptor valve position. The interceptor valve thereafter will reach a wide open position at a predetermined load. During the speed control mode of operation the control signal which controls the positioning of the interceptor valve is modified by certain pressure conditions at the input of the interceptor valve after the preset speed is attained.

Patent ES-8607408-A1 (ES)
Title: Process and apparatus for adding calcium to a bath of molten ferrous material.
IPC: C21C7/04
Filed: 1985-08-01
Abstract: A process for adding calcium to a bath (2) of molten ferrous material is disclosed in which a calcium metal-containing wire (1) is fed through a refractory lance (5) into the bath (2). Recirculatory stirring of the molten ferrous material is accomplished with an inert gas flow through the lance (5). The caicium-containing wire (1) is fed at such a rate that it substantially bends towards the horizontal direction after it leaves the lance (5) and melting of the calcium in the wire (1) occurs primarily in or directly below a region of downwelling of the molten ferrous material. Suitable wire feeding rates will depend upon the disposition of the lance (5) in the bath and the composition (e.g. clad or unclad) and cross-sectional dimensions of the calcium metal-containing wire (1). A preferred apparatus for adding processing elements in wire form directly into a molten material comprises a heat resistant nozzle (60) positionable relative to the surface of the molten material such that an inlet is disposed above the surface and an outlet (84) is disposed beneath the surface a mechanism (24) for feeding the wire (20) through the nozzle (60) directly into the molten material and a system (31, 33, 42) for injecting a substantially inert gaseous medium into the molten material together with the wire (20), whereby the inert gas substantially prevents closure of the nozzle (60) by solidified molten material and promotes mixture of the processing elements with the molten material through gas bubble agitation. The apparatus further comprises a substantially gas-tight conduit (44) connected to the nozzle inlet, through which the wire (20) and the inert gaseous medium are delivered to the nozzle (60). A pressure-driven seal (30) prevents atmospheric contamination and prevents loss of inert gas. Passing the wire (20) and gaseous medium through a bore in the nozzle (60) having an elongated, gradually tapered funnel-shaped section (80) adjacent the outlet (84) maximizes the effect of the inert gaseous medium.
