Title: Preparation of selective surfaces for high temperature solar energy collectors
IPC: C23C14/24
Filed: 1979-01-24
Abstract: Previous attempts to prepare selective surfaces suitable for use in high temperature solar energy collectors have included chemical vapour deposition of metals on to substrates. Such coated substrates have not been successful due to impurities in the coatings and to agglomeration due to auto-diffusion. These problems are alleviated by metal vapour thermal deposition of a layer of metal or alloy whose crystalline size is such that the surface contains holes whose mean diameter is of the same order of size as the wavelength band of visible light. The characteristics of the coating may be varied by varying the gaseous atmosphere e.g. air, oxygen, nitrogen, argon, gaseous hydrocarbon in which the deposition is performed and the speed e.g. 1 to 10 microns per minute and temperature e.g. 1500 DEG C to 2000 DEG C of vaporisation and deposition. Preferably the vaporised metal is kept out of contact with the substrate for a period of time after the metal has been melted, to avoid impurities which adversely affect the coating.

Patent ES-8101898-A1 (ES)
Title: On/off sprinkler.
IPC: A62C37/08
Filed: 1980-02-27
Abstract: An on/off sprinkler has a body defining an extinguishant inlet and outlet and is divided internally by a diaphragm defining with the body an intermediate chamber and normally isolating the inlet from the outlet. The diaphragm has a drain orifice allowing an extinguishant pressure balance on both sides of the diaphragm.

Title: Television receiver high frequency regulated power supply including a low voltage ferroresonant transformer coupled to a step-up high voltage transformer
IPC: H04N3/185
Filed: 1982-03-26
Abstract: A source of high frequency alternating input voltage is coupled to the primary winding of a high frequency low voltage ferroresonant transformer of a television receiver power supply. A capacitor is coupled across the secondary output winding of the ferroresonant transformer, and generates a circulating current that magnetically saturates the secondary core portion of the transformer to regulate the alternating polarity output voltage developed across the secondary output winding. A step-up high voltage transformer includes a primary winding and a high voltage secondary winding tightly coupled to the step-up transformer primary winding. The regulated alternating polarity output voltage developed by the low voltage ferroresonant transformer is coupled to the primary winding of the step-up high voltage transformer without prior DC rectification of the ferroresonant transformer output voltage. The applied, regulated ferroresonant transformer output voltage develops a regulated high voltage across the step-up transformer high voltage secondary winding. A high voltage rectifier arrangement develops an ultor voltage from the regulated high voltage.

Title: Device for reading printings on a moving article.
IPC: G06V10/12
Filed: 1984-01-20
Abstract: It is often necessary to identify articles or packages in large numbers for sorting or subsequent processing so as to pass them to the appropriate point or to the further processing point. For this purpose reading devices are used to detect printed characters on the article as it is passed on a conveyor through the lens field of a detecting camera, whereby a printed character consisting of dots and situated in the lens field of the detecting camera is detected and converted into signals for controlling the subsequent routing of the article. The intention is to simplify and improve the method of printing and reading the characters. To solve this problem, the lens field is divided up by a grid, the spacing of which at the most is the same as the diameter of one dot of the printed character.

Abstract: The scuff-resistance of a high-pressure laminate is improved by incorporating in or very near the surface thereof, finely divided polyethylene wax preferably having a particle size of about 1-25 microns and a melting point of 220 DEG -230 DEG F. The wax is incorporated as part of a coating mixture applied to the face of an unimpregnated decor paper sheet in an ultra-thin layer, which layer is dried at atemperature below the wax melting point and then impregnated with conventional melamine-formaldehyde resin. The impregnated sheet is placed onto a sheet of convention phenolic resin impregnated core sheets and consolidated in the conventional way under heat and pressure. During consolidation, the wax particles "bloom", or migrate to the surface. The finished laminate surface has greatly improved scuff-resistance.
