Patent ES-353476-A1 (ES)
Title: A Process for the Production of Synthetic Resin Impregnated Wood
IPC: B27K3/15
Filed: 1968-05-03
Abstract: Synthetic resin impregnated wood is prepared by impregnating wood with an organic liquid which can be polymerized or hardened and optionally contains dissolved polymers, plasticizers, accelerators, initiators and hardeners, under a reduced pressure followed by hardening wherein the dried wood is dipped into a bath containing the impregnating solution, a reduced pressure is created at least once, and the wood is removed from the bath after restoration of normal pressure, and the impregnated liquid is hardened. The reduced pressure may be generated by working in an evacuable vessel, or by heating the wood prior to immersion in the bath, to a temperature higher than the bath temperature and then dipping the wood into the bath. In the examples various woods are impregnated with the following solutions: (1) methyl methacrylate lauroyl and diacetyl peroxide, optionally mixed with a prepolymer of methyl methacrylate in another solution the lauroyl peroxide is dissolved in dioctyl adipate, and the diacetyl peroxide is dissolved in dimethyl phthalate, (2) a polyester based resin (65% of an unsaturated solid resin and 35% of styrene) methyl methacrylate, lauroyl and diacetyl peroxide, (3) styrene, a prepolymer of styrene, lauroyl and diacetyl peroxide, (4) an epoxide resin and a hardener, (5) a prepolymer of methyl methacrylate, methyl methacrylate, benzoyl peroxide in dibutyl phthalate, and (6) styrene, a prepolymer of styrene, lauroyl and acetyl peroxide. Compressive tests were carried out on the above impregnated woods.

Title: An Electromagnetic Pump with a Built-In Thermoelectric Generator
IPC: H02K44/04
Filed: 1968-06-06
Abstract: In a storage coffin for a spent nuclear assembly the assembly is immersed in liquid sodium which is circulated by an electromagnetic pump. In the latter, a thermocouple generates an electric current in the sodium which reacts with a magnetic field to provide the pumping action. In the pump, the struts 2, 3 connect the radiator 4 with the sodium duct 1. The struts are of iron and constantin respectively and generate a current in the sodium due to the temperature difference between 1 and 4. The permanent magnets 5, 6 cause the liquid sodium to be circulated along the duct. The pump is mounted beneath the cell 16 to which it is coupled by the ducts 1 and the sodium circulates in the annular chamber 17 downwards through the fuel assembly 15. The heat released from 15 is transferred by the liquid metal to the walls of 16, from which it is dissipated by heat exchange with the surrounding atmosphere.

Title: Method of decontaminating radioactive wastes
IPC: B01J39/02
Filed: 1968-11-22
Abstract: Liquid radio-active effluent is decontaminated by adjusting the pH to 1-3, percolating over activated finely-divided iron at a temperature not exceeding 70 C., raising the pH to 8-10, and treating with a zeolite. The iron may be used in the form of a powder or as steel wool, and may be activated by degreasing and contacting with a Cu, Ni, Co and/or Mn salt solution, or by heating in hydrogen at 900 C. As a preliminary step Zr may be precipitated as phosphate or hydroxide. The process is especially useful for treating wastes containing Ru or low activity wastes containing Ru or low activity wastes previously treated by co-precipitation or ion exchange.

Patent ES-432184-A1 (ES)
Title: Device for printing coded labels and the like
IPC: G06K1/12
Filed: 1974-11-22
Abstract: A device for printing coded labels that comprises a motor rotated printer. The printer has a series of printing elements in the form of electromagnets that are adjusted to operate at its resonant frequency and that are arranged in sets or banks on opposite sides of the rotational axis and in a row that extends through the rotational axis. Upon command that selected information be printed in code form, the reversible motor is started to rotate in one of its opposite directions and then a print cycle is initiated during which one set of the printing elements is continuously enabled whereas the other set is enabled in accordance with the information to be coded. The printer thereby develops during 180 DEG of its rotation on half of a series of rings that are all of the same width and during the subsequent 180 DEG of its rotation the remainder of the rings with widths determined by the coded information. Thus, logic ONES and logic ZEROS are developed which are also referred to as digital pairs. When a subsequent label is printed with the same or different coded information, rotation of the printer by the motor is in the opposite direction. Thus, the direction of rotation is changed after each label is printed. A sensor is drive connected to the printer so as to determine the print cycle and direction of rotation of the motor.
