Patent ES-476961-A1 (ES)
Title: Method for the manufacture of externally coated tube from steel strip and tube made by the method.
IPC: B21C37/08
Filed: 1979-01-18
Abstract: Externally coated steel tube is made from steel strip by longitudinally folding and welding the strip to form the tube (200), preheating (205) the tube and applying powder (206) to the exterior of the preheated tube. The tube is then baked at a higher temperature before cooling. In order to achieve an even and continuous coating when using thermosetting material as the coating powder, the temperature given to the tube by the preheating (205) is such as to cause the coating powder to melt and spread out immediately on application to form a substantially continuous coating, before substantial curing of the coating material occurs. Suitably, this is provided by passage of the tube through a box (207) which maintains the temperature of the tube.

Patent ES-480476-A1 (ES)
Title: Stratified-charge two-stroke internal combustion engines
IPC: F02B17/00
Filed: 1979-05-11
Abstract: In a crankcase scavenged two-stroke internal combustion engine, a duct and at least one further passage extends between the crankcase chamber and the combustion chamber. There is a fuel/air mixture port leading into the duct and a pure air port leading into the duct or the crankcase chamber. The passage exits into the combustion chamber between the exit into that chamber from the duct and an exhaust port leading out of the combustion chamber. In operation fuel enters the combustion chamber in the air of the fuel/air stream entering the duct and air is additionally pushed into the combustion chamber by the downward movement of the piston through the passage and the duct. The fuel is separated from the exhaust port by a layer of air leading to better fuel consumption and higher oxidation combustion products.

Patent ES-8104144-A1 (ES)
Title: Process for Producing Aluminium Fluoride
IPC: G01N27/02
Filed: 1980-04-30
Abstract: The invention concerns processes for the production of high purity aluminium fluoride tri-hydrate by the reaction of fluosilicic acid with aluminium hydroxide, filtering off SiO2 and precipitating ACF3 3H2O in the metastable filtrate, wherein the course of the reaction is checked or controlled by means of measurements of specific electrical conductivity. Usefully, no excess fluosilicic acid or aluminium hydroxide need be used in the process. Furthermore, fluctuations in the reaction parameters, viz: the quantities, concentrations, and temperatures, can be kept under control by means of a variable reaction time and can be compensated for. This leads to a constant, optimal yield and to reproducible constant conditions for filtering off the silica. The problems which arise in production as a result of the silica being difficult to filter off, due to not properly maintaining the operational parameters, can therefore be avoided by means of the said process.

Patent ES-8207351-A1 (ES)
Title: Dual frequency anti-theft system.
IPC: G08B13/18
Filed: 1981-10-08
Abstract: An anti-theft tag (34) containing a semiconductor diode (36) connected to a metal antenna loop (38) is configured to receive two distinct radio frequency transmissions. The diode (36) bridges a closed loop at one end of the antenna (38), forming a tank circuit resonant at twice a selected center frequency. A first transmitter (26) generates a tone modulated radio frequency (f) displaced on one side of the center frequency, and a second transmitter (30) generates a continuous wave radio frequency (f) displaced on the other side of the center frequency. Both signals are fed separately to respective dipole radiating antenna strips (18, 19, 20, 21) on opposite sides of a surveillance area. The dipole strips for the different frequencies are at right angles to each other on each side those for the same frequency are at right angles to each other on opposite sides. This produces cross polarized transmission of both frequencies within the area. Diode (36) of tag (34) mixes the two frequencies received by the antenna loop (38), causing the tank circuit to resonate at the sum of the two frequencies (double the center frequency). That resonant frequency is reradiated to receiver antennae (22, 24) on each side for detection by a very narrow band receiver (42) responsive to the sum frequency. The modulating tone is derived from the received signal and processed to trigger an alarm (44) when the detected signal is of sufficient strength and duration.

Compounds of this kind act to some extent as blockers and to some extent as stimulators of beta -adrenergic receptors with more or less pronounced cardioselectivity and can accordingly be used, on the one hand, in the indications customary of beta -blockers and, on the other hand, for the treatment of insufficient heart output, asthma and circulatory disorders.

Patent ES-8309049-A1 (ES)
Title: Method and apparatus for operating a microprocessor in synchronism with a video signal
IPC: H04N5/445
Filed: 1982-06-25
Abstract: A microprocessor is provided in a television receiver which is responsive to a clock signal phase locked to a recurrent signal component of a composite video signal, such as a horizontal line rate signal component. The clock signal frequency is chosen to be an integer multiple of the recurrent signal component and to enable the microprocessor to execute an integer number of uniform instruction cycles during an integer number of periods of the recurrent signal component. The execution of the instruction cycles is brought into a real time phase alignment with the recurrent signal component by causing the microprocessor to execute an instruction during a time interval which is greater than the time required to execute one of the uniform insturction cycles. The phase of subsequently executed uniform instruction cycles is shifted in this manner until signal sampling indicates that the desired phase relationship has been achieved.
