Patent ES-434824-A1 (ES)
Title: Method and apparatus for applying coating compositions to strip material
IPC: B05C1/08
Filed: 1975-02-18
Abstract: A coating material such as a high viscosity, low solvent content paint is applied to metal strip by means of a coater which comprises a soft-covered take-up roll which draws coating material from a reservoir and coacts with a hard metering roll (from which excess coating material is continuously removed by a doctor blade), to form a metered film on the surface of the take-up roll. The metered film is transferred to a small diameter hard transfer roll from which it is in turn transferred to a soft covered applicator roll, by which it is applied to the strip. At each line of contact between two rolls or between the applicator roll and the strip the mutually contacting surfaces travel in opposite directions (i.e., the rolls all rotate in the same sense). Preferably the peripheral speed of the applicator roll is greater than that of the transfer roll, which is greater than that of the take-up roll, but the strip speed is preferably lower than that of the applicator roll.

Title: Inspection machine memory
IPC: B07C5/12
Filed: 1976-03-01
Abstract: An improved memory for a glass container inspection machine. In one common form of glass container inspection machines, the containers are indexed through multiple stations where they are inspected for various attributes. Rejection of defective containers can take place only after all of the inspections have been made. The information relative to a defective container is placed in a master-slave type flip-flop uniquely associated with a particular inspection station. Information is then shifted through a group of series-connected master-slave type flip-flops in synchronism with the movement of the container until the container, if defective, reaches a location where it can be rejected. The information is moved or clocked by a generated clock pulse that has a rise time that is faster than the information transfer time through the flip-flops.

Patent ES-454483-A1 (ES)
Title: Tape drive for a cassette in a sound reproducer and/or recorder
IPC: G11B15/18
Filed: 1976-12-22
Abstract: An axial-gap flat type motor with an annular permanent magnet and a non-magnetic disk rotor with a printed winding directly drives a coaxial tape capstan and indirectly drives the spindles engaging the supply and take-up reels in the cassette. The capstan and the spindles are shifted in a direction parallel to the motor axis in moving between an idle position and an operating position, the insertion of a cassette being sufficient to cause movement into the operating position. The capstan shaft accordingly is axially displaceable in the motor, shifting within the movable inner portion of a central bearing to which the rotor is affixed. The capstan shaft has radial projections engaging internal grooves in the movable bearing portion and springs urge these projections towards one or the other of their axial end positions in the bearing, corresponding respectively to the idle and operating positions of the capstan. Current is fed to the rotor by spring-pressed studs located in the central bearing and the annular permanent magnet stator. Light passing through slots in the edge of the rotor disk is optoelectrically detected to produce a speed regulating signal to a regulating circuit that controls the voltage of which current is supplied to the motor. The low moment of inertia of the drive makes the speed regulation accurate and facilitates transitions into and out of fast-forward and fast-rewind modes. The printed windings on the rotor produce smooth motion in response to direct current excitation.

Patent ES-461756-A1 (ES)
Title: Maximum-power motor
IPC: G01R21/133
Filed: 1977-08-19
Abstract: A maximum-power monitoring device and method whereby a direct-current voltage is derived which is proportional to the instantaneous power and is converted into a train of pulses in a voltage-frequency converter proportional to the power and these pulses are summed during an interval between two successive cyclic pulses. When the total exceeds a threshold value, a flip-flop is triggered. The state of the flip-flop controls a shift register which is periodically stepped with each cyclic pulse and "read". The reading is used to control a logic circuit, when it exceeds a predetermined value, for cutting off in accordance with predetermined (programmed) priorities, the loads or load sections of the monitored system. As a result, the mean peak demand is held at a predetermined level.

Patent ES-465349-A1 (ES)
Title: Device for the supply of fluid to the root system of a tree a bush or other type of plant
IPC: A01G29/00
Filed: 1977-12-22
Abstract: The device comprises an injection tube (1) which is inserted into the ground to distribute the liquid at a given depth. Similar devices are known, which, however, have inter alia the disadvantage that said liquid rises back up along the tube and disperses on the surface of the ground. The illustrated device, however, is designed in such a manner that this does not happen because, once the injection tube (1) has been installed in the ground, the liquid emerges through openings (15, 16, 17, 18, 19) which do not come into contact with the surrounding ground since they are provided on a part (5) of polygonal shape with a radial dimension which is smaller in relation to the circumference (23) of the tube. There thus come to be formed on the injection tube (1) shoulder-type surfaces or flanges (24, 25) which prevent the liquid rising back up along the tube and dispersing on the surface of the ground.

Patent ES-8103197-A1 (ES)
Title: Process for baking carbon electrodes.
IPC: F27B13/00
Filed: 1980-05-16
Abstract: In the baking of carbon anodes (for aluminum reduction cells) or the like, in so-called ring-type furnaces where green carbon bodies are deposited in pits, each of which is circumstanced successively for preheating stages, one or more baking stages, and cooling stages, while air travels in heat exchange relation through flues past a series of pits respectively undergoing such cooling, baking and preheating operations, improvement is effected by introducing water spray into the air as it flows past the pits at a cooling region. Such water, first as spray and then as vapor, increases the quantity of heat that can be absorbed by the air flow and also increases the heat transfer coefficients of the flue walls in the cooling regions, so as to provide recovery or removal of heat in greater amount or more rapidly. The vapor-containing air, advancing through the localities of baking fire in the flues and then the preheating regions, enhances the heat exchange between the gas and the flue walls and can permit higher baking temperature of the carbon bodies. A particularly important result is reduction in the overall time of the process (preheating, baking, cooling), and correspondingly in cost, e.g. as related to the production of aluminum. Suitable apparatus is a ring-type furnace with nozzles for introducing water spray into the flues that run past the carbon-containing pits. The nozzles can be connected in a manifold across the parallel lines of pits, which can be shifted as such whenever pits are brought into and removed from an operating sequence.
