Patent ES-372140-A1 (ES)
Title: Method for the production of castings from alloys of metals and gases
IPC: C21C7/10
Filed: 1969-10-02
Abstract: Method of and apparatus for dissolving a gas in molten metal and casting the metal in that condition. During the casting process a reservoir with the melt and the mold for the casting are disposed in separate chambers, such chambers being subjected to the pressure of an atmosphere composed by the gas to be dissolved in the molten metal and some other gas which is inert to the metal, the gases being present in such proportion that the partial pressure of the gas to be dissolved in the chamber with the mold is higher than that in the chamber with the reservoir for the melt. Thus, the solubility of the gas, which depends upon its partial pressure, may be equal in the melt, as well as in the solidifying metal the total gas pressure in both chambers may be chosen in accordance with the requirement of the casting process, so that the melt may be conveyed to the mold.

Title: Barrier gate
IPC: G07B15/06
Filed: 1970-05-25
Abstract: A lifting barrier controlling access to a car park comprises a horizontal arm 5 extending perpendicularly to the plane of rotation of a carrier arm 4 mounted on a shaft 2 of lifting mechanism in a stanchion 1.

Patent ES-433270-A1 (ES)
Title: Apparatus for separation of waste material from a moulded article
IPC: B29C37/00
Filed: 1974-12-23
Abstract: A method of and apparatus for separating off waste material from a moulded article in the production of hollow articles of thermoplastics material by a blowing process in a multi-part mould involves pinching together regions of a partly-made article during closure of the mould parts around it and once a satisfactory weld seam has been created at the pinch regions then increasing the closure speed of the mould parts. Control of the mould closure speed may be effected by open loop control or by automatic control, and may be made dependent on time and/or on displacement of the mould parts. The increased final closure speed can with advantage be equal to the mould closure speed at which the mould parts are moved up to the beginning of the pinching process.

Title: System for self-cleaning ink jet head
IPC: G01D15/18
Filed: 1976-11-16
Abstract: A system for fluid jet heads such as ink jet adapted for self-cleaning of certain clogs and purging of air from the head. The head includes a manifold communicating with at least one orifice to project a stream of fluid therefrom. Two fluid supply paths at different sides of the manifold supply pressurized fluid thereto. One of the supply paths is located at the top of the manifold and is reversible. If air or an impurity causing a nozzle clog is encountered in the head, the top path may be reversed so the fluid enters from one path and exits at the top. This establishes a crossing flow at the orifice, tending to loosen and remove the clog and purging the impurity or air from the head and out the reversible path.

Patent ES-459881-A1 (ES)
Title: Process for refining molten metal
IPC: C21C7/072
Filed: 1977-06-17
Abstract: The refining gas, for example nitrogen, is injected into the molten metal by means of an injection device comprising a rotor (1) with fins (2), driven by a vertical shaft (3) surrounded by a stationary sleeve (4). The gas is introduced through an annular passage arranged between the shaft and the sleeve and comes out by virtue of a clearance provided between the rotor and a grooved stator (11). In the molten metal, the rotor creates currents which make the bubbles of refining gas travel outwards and downwards, and this improves the gas-metal content. Since the gas is preheated in the sleeve (4), the bubbles do not expand within the metal and remain small.

Title: Supervisory circuit for redundant channel control systems
IPC: G05B9/02
Filed: 1979-03-22
Abstract: The invention is directed to a supervisory circuit for a control system of the type having a plurality of redundant input channels and a single output channel. More specifically, the invention is directed to a supervisory circuit for a two-channel redundant control system that provides reliability approaching that of a three-channel system. The supervisory circuit operates on the assumption that the majority of control circuit failures are catastrophic. The supervisory circuit includes a channel select circuit that receives the outputs of both of the identical control circuits and determines the faulted channel. Determination of the faulted channel is accomplished by a two-step comparison. In the first step, the outputs of both channels are compared with a previously stored output, or average of previous outputs. In the second step, signals representative of the absolute difference between each channel output and the stored output are compared. The polarity of the output of the second comparison determines the faulted channel. Normally, a manual channel select switch determines which channel is used as the output of the control system. In one embodiment of the invention an independent trip circuit determines when a fault has occurred in one of the two channels and disables the manual channel select switch in favor of the channel selection made by the channel select circuit. In another embodiment of the invention, the output of the channel select circuit is directly used to determine whether a fault has occurred and when the manual channel select switch should be disabled in favor of the channel select circuit.
