Patent ES-400382-A1 (ES)
Title: Fast-firing ceramic composition and ceramic article made therefrom
IPC: C04B33/13
Filed: 1972-03-03
Abstract: Scrap glass is crushed and mixed with selected quantities of ball clay and wollastonite, the resulting raw-mix is press-molded into a green compact, and the latter is fired in air at a temperature above the softening point of the glass particles to provide a ceramic article that has a dense impervious structure and is electrically non-conductive. Selective amounts of bentonite and an inorganic pigment can also be included in the raw-mix formulation and talc, petalite or potter's flint can be substituted for the wollastonite. By properly correlating the molding pressure and firing schedule with the raw-mix formulation, the ceramic articles can be rapidly and economically mass-produced in various shapes and sizes. The invention is especially adapted for use in fabricating preformed insulator components for electric lamp bases and similar devices and, in addition to reducing their manufacturing cost, recycles large quantities of scrap glass such as bottles and the like which would otherwise pollute the environment.

Patent ES-417863-A1 (ES)
Title: Apparatus for heating fluids
IPC: F24H1/16
Filed: 1973-08-13
Abstract: An apparatus for heating or evaporating liquids or gases in which a homogeneous gaseous mixture of fuel and oxidizing agent is passed through a gas-permeable bed of a radiation substance, in which it undergoes flameless combustion with an extremely high intensity, so that the entire heat is converted into radiation emitted by the radiation substance. The radiation substance transmits heat in this form to a system of hollow jackets, which are preferably of cylindrical or prismatic formation, co-axially placed one inside the other so as to produce continuous annular spaces between neighbouring jackets, said spaces being filled with the radiation substance. The apparatus thereby disperses with surfaces for heat exchange by convection.
Patent ES-424233-A1 (ES)
Title: Method of corrugating a web of thin thermoplastic material in a continuous production
IPC: B29C53/24
Filed: 1974-03-13
Abstract: Method for continuously forming a corrugated web of thermoplastic material in which the corrugations extend diagonally across the web. The web is first softened by heat and then passed to a molding belt which moves in an endless path while supporting and advancing the web in a longitudinal direction. The molding belt is provided with grooves corresponding to the corrugations in the web. The corrugations are formed initially by poking the softened web progressively into the grooves without stretching the web to any substantial degree. The thus initially formed corrugations are thereafter drawn into the grooves and retained therein by applying suction to the bottom side of the molding belt.

Patent ES-458065-A1 (ES)
Title: Inductive load driving amplifier
IPC: H01L27/07
Filed: 1977-04-21
Abstract: An inductive load driving amplifier is disclosed which includes two serially connected transistors, with Zener diodes limiting the collector-emitter voltage of the one and diverting the collector-base current of the other when the first one switches off. The driver is implemented as an integrated circuit. This collector isolation constitutes a high voltage Zener diode which contributes to limit the collector voltages. The combination of these features prevents the device from being exposed to second breakdown when switching highly inductive loads (e.g. several Henrys under 50V), thereby avoiding the harmful effects of breakdowns during switching.
Patent ES-459604-A1 (ES)
Title: Upgrading of magnesium containing materials
IPC: C22B3/00
Filed: 1977-06-08
Abstract: This invention is concerned with the recovery of relatively pure magnesia from magnesite which is normally contaminated with too much silica and silicates to permit the magnesite simply to be calcined for the recovery of refractory grade magnesia. The magnesite in its raw uncalcined state is treated with SO2 at elevated temperatures preferably between 50 DEG and 60 DEG C. thereby rapidly dissolving a high proportion of magnesium as bisulphite without the cost of initial calcination and without dissolving above about 1% of SiO2 present in the magnesite. The solution of magnesium bisulphite can thus be purified by filtration and magnesia may be recovered in known manner from the purified solution.

Title: Vibratory device for feeders and the like.
IPC: B06B1/16
Filed: 1978-12-28
Abstract: A vibratory device operable as a two mass vibrating system for driving a work member as used in feeders, screens, conveyors and the like, employs a motor driven eccentric weight exciter attached to one mass which is spring coupled to a second mass with the entire device being supported by isolator springs. The spring coupling is adjustable in a generally vertical plane to vary the direction of application of the exciter forces transmitted from the first mass to the second mass to fix this direction as conditions of use call for, the second mass being vibrated with the work member forming a part of such second mass to perform the work produced by the vibratory device in driving the work member. A D.C. brush or brushless motor is particularly useful to drive the exciter for driving relatively small work members to achieve ease of changing the rotative speed of the eccentric weight exciter as conditions dictate.
