Title: Fixed frequency, variable duty cycle, square wave dimmer for high intensity gaseous discharge lamp
IPC: H05B41/288
Filed: 1979-09-10
Abstract: A dimmer circuit for an HID lamp is provided for supplying a square wave current therethrough at a constant frequency, but whose duty cycle is variable dependent on a sensed current level. The circuit employs a first pair of transistor switches for reversing polarity through the lamp at a low frequency rate. Associated with each of those transistors is a circuit having a transistor switch connected to a drive circuit employing a timer network. The timer network produces an output that is a square wave, the leading edge of which occurs at regular intervals at a high frequency rate. The trailing edge occurs dependent on a dim/bright voltage setting and upon the amount of current through a sensing resistor in series with the lamp.

Patent ES-8105164-A1 (ES)
Title: centrifugal separator
IPC: B04B1/14
Filed: 1980-09-04
Abstract: This invention relates to centrifugal separators of the kind having sludge ports at the rotor periphery to be opened during operation and separate outlets for separated heavier liquid phase and separated lighter liquid phase. To reduce the losses of valuable lighter liquid phase during total discharge or partial discharge of the separator by opening the sludge ports, the centrifuge is provided with an overflow device connected to the heavy phase outlet, said overflow device having an inner annular overflow and also having a number of passages at a larger diameter than the inner overflow border. The passages are dimensioned to let through all heavier liquid phase in normal operation but not to let through an increased amount of heavier liquid phase fed to the separator just before opening the sludge ports for the purpose of displacing the interface between the heavier and the lighter liquid phase towards the rotor axis to a level that corresponds to said inner overflow border. In order to push the interface between the liquid phases inwards before discharge, no other action is therefore needed than an additional supply of the heavier liquid phase.
Patent ES-8303541-A1 (ES)
Title: Zinc-alloy coated ferrous product resistant to embrittlement.
IPC: F01N13/16
Filed: 1980-12-15
Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. For a plain content steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc. By use of such high phosphorus ferrous base, for the reception of a zinc containing alloy coating, an improved metallic coated ferrous product has been found which resists intergranular penetration by zinc and embrittlement of the ferrous base. Such coated product has extended service life at temperatures above about 450 DEG F. (232 DEG C.) and when restored to room temperature possesses a high degree of ductility.

Patent ES-8302374-A1 (ES)
Title: Method and device for the optimum use of at least one variable and hard to master power source.
IPC: F02B3/06
Filed: 1981-08-14
Abstract: A method and an installation are described for the optimum use of at least one variable power source which is difficult to control. In known power systems with a power source which is difficult to control, it is normal to couple to it one or more synchronous A.C. generators which can be connected with a rectifier and an inverter to an autonomous A.C. network. In this arrangement, the A.C. network is connected to a second synchronous A.C. generator which is mechanically connected, such that it can be disconnected therefrom, to a controllable auxiliary machine, such as e.g. a diesel generating set. To keep the frequency of the network constant if too much power is offered or, above all, if the power offered drops, such an amount of power is supplied from the autonomous A.C. network (5) to an additional usable load (2) that the frequency of the network (5) remains constant. The excess power to be diverted can be used, for example, for the preparation of hot water or for the electrolysis of water, combined with the use of fuel cells, or for battery charging or for pumping water to increased heights.
Patent ES-8306402-A1 (ES)
Title: Friction disc clutch/brake combination
IPC: F16D67/04
Filed: 1982-06-18
Abstract: The invention proposes a friction disc clutch/brake combination, preferably for intermittently driven presses, shears or the like, with a clutch unit and a brake unit, in which, to satisfy safety requirements, the reciprocal actuation of the clutch and brake unit is effected by two systems completely identical in their action and connected in parallel. One system comprises a central pressure disc (6) which is arranged in axially displaceable fashion between the clutch and the brake unit and presses the clutch discs (2) and the brake discs (4) alternately against the associated outer pressure discs (10, 12). The second system comprises these same outer pressure discs (10, 12), which are connected firmly to one another mechanically and are likewise arranged in axially displaceable fashion, allowing the clutch discs and the brake discs to be pressed alternately against the intermediate pressure disc. In order to engage the clutch or the brake, all that is required is thus a corresponding movement of these two systems relative to one another, it being irrelevant in principle whether this movement is carried out by one system or the other or by both systems, for which reason functioning is fully maintained if one system fails.

IPC: A22C13/02
Filed: 1982-10-13
Abstract: The device for axially rippling synthetic tubular material (12), particularly an artificial skin for producing sausages, comprises a cylindrical mandrel (10) extending longitudinally. At least two rippling wheels (20), synchronously driven, are provided around the mandrel. They are further driven circularly about the axis of the mandrel. They carry wing-shaped teeth (26), having a thin wall, cut as an arc of a circle corresponding to the cross-section of the mandrel. The teeth (26) are arranged with respect to the axis (24) of the wheel so that the tangent (30) to the trajectory of the extremity of the teeth forms an acute angle (< 90<o>) with the front face of each tooth being at least in the rotation quadrant wherein it is in maximum engagement with the mandrel (10). With such arrangement, a fast radial sliding of the teeth at an acute angle with the axis of the mandrel is obtained from the last ripple formed. Thereby, defects in the formation of ripples as well as damages to the tubular material are avoided.
