Patent ES-8102709-A1 (ES)
Title: Load equalizer for press tooling
IPC: B30B15/06
Filed: 1980-07-02
Abstract: A pair of press tools, such as punches, are mounted on a tool support for axial reciprocation between extended and retracted positions with respect to the support. The tool support may be defined by a press slide, bed or component part of a tooling package mountable thereon and is provided with a hydraulic fluid receiving cylinder for each of the tools. Each tool is interconnected with a piston received in the corresponding cylinder and the cylinders are in flow communication with one another. Accordingly, if one of the tools engages a workpiece before the other during operation of the press, the one tool is displaced in the direction of retraction causing the other tool to be displaced in the direction of extension until both tools engage the workpiece, thus to avoid eccentric loading of the press slide and frame. Both tools have a neutral position with respect to their extended and retracted positions and, upon movement of the press slide away from the work, a biasing arrangement returns the extended one of the tools to its neutral position and the displacement of the corresponding piston causes the retracted tool to be returned to its neutral position.

Patent ES-8406826-A1 (ES)
Title: Automatic bias control system for an image reproducing device
IPC: H04N9/72
Filed: 1983-10-07
Abstract: An automatic kinescope bias (AKB) control system includes a sampling amplifier (52) which provides an output current for charging and discharging a storage capacitor (56) in response to the amplitude of a derived pulse V1) representative of the black current level conducted by the kinescope of a television receiver. The derived pulse amplitude is greater than zero when the black current level is correct, and is applied to the amplifier via an input signal coupling path. During sampling intervals, an auxiliary pulse (Vp) is applied to the input signal path with a magnitude and sense for negating the amplitude of the derived pulse at the amplifier input when the derived pulse amplitude corresponds to the correct black current level. Accordingly, the amplifier conduction and the voltage on the storage capacitor remain unchanged. An impedance included in the signal path compensates for impedance variations at a sense point from which the black current representative signal is derived.
Patent ES-8406707-A1 (ES)
Title: Furnace arrangement to smelt metal and to keep it heated.
IPC: H05B6/20
Filed: 1983-10-14
Abstract: A furnace for melting and melt-heat retaining of metals has two horizontal interspaced furnace vessels which form a melt chamber and each having a side wall facing the side wall of the other furnace vessel, each side wall having an opening horizontally aligned with the opening of the side wall of the other furnace vessel. A single inductor is positioned between these side walls and is formed by an integral block of ceramic having opposite ends abutting the outside of the side walls. The block has a transverse through-hole and two longitudinal through-holes straddling the transverse through-hole and open to the two furnace vessels so that they intercommunicate. The inductor has a core with an energizing coil and having a leg extending through the transverse hole. When the energizing coil is powered a melt in the two longitudinal through-holes is heated by an induced circuit which extends into and through melts in the two furnace vessels. When required, the inductor can be shut down and the melt heat-retaining is effected because the furnace vessels have roofs mounting electric resistance heaters of low power which can be operated at that time.
Patent ES-8505570-A1 (ES)
Title: Adjustable machine reamer.
IPC: B23D77/04
Filed: 1984-01-03
Abstract: In the known, adjustable, single-cutting-edge machine reamers having a turnable cutting plate, the adjusting and re-adjusting operations are awkward and associated with difficulties because, at least as far as adjusting is concerned, adjustments have to be made at two points, and moreover for adjusting to the set desired value it is generally necessary to proceed in a step-by-step manner, gradually working ones way up to the desired value. These problems are due to the fact that adjustment can in principle only be made in the forward direction, that is to say in the direction of increasing diameter, whereas reverse adjustment in the proper meaning of the term is not possible but can only be achieved indirectly by carrying out a new adjustment with a lower starting value and adjusting in a forward direction. These problems and other disadvantages of these reamers are eliminated by a new overall concept employing a turnable cutting plate (3) in the form of an equilateral polygon, said turnable cutting plate being adjustable by means of an adjustable stop and an fixed stop (15, 14) on the polygon-sides (45, 44) of the turnable cutting plate inclined toward each other and a securing screw (17) for the turnable cutting plate acting as a springy restoring element and hence also enabling reverse adjustment to be effected.

Patent ES-8701101-A1 (ES)
Title: Microwave heating package.
IPC: B65D81/34
Filed: 1986-01-28
Abstract: A novel cover (38, 40, 48) arrangement is described for use with foodstuff holding pans (30) to be heated in a microwave oven. The cover is one which in terms of microwave energy, does not transmit reflected energy. Thus, the cover acts in a manner analogous with non-reflecting coatings in optics and permits passage of the microwave radiation into the container holding the foodstuff (18), while substantially preventing escape of microwave radiation reflected from the foodstuff surface and container bottom (32). In this manner the microwave energy is retained and concentrated within the container, resulting in more efficient and uniform heating of the foodstuff. The novel cover is particularly valuable when used with aluminium foil pans, which without the cover of this invention seriously reflect microwave radiation.
