Patent ES-463078-A1 (ES)
Title: Adaptive autopilot for marine vessels
IPC: G05D1/02
Filed: 1977-10-10
Abstract: An autopilot automatically adjusts the sensitivity of a ship's steering system to accommodate changes in speed as well as sea and wind conditions. The autopilot utilizes heading error, speed and speed squared signals to produce a rudder order signal for controlling rudder position. The rudder order signal is developed in a heading keeping circuit unless a heading change greater than a predetermined threshold is commanded, in which event a programmer substitutes a heading change circuit for the heading keeping circuit. The sensitivity of the heading change circuit is automatically adjusted as an inverse function of vessel speed squared, and automatic rudder order limits are established in the same circuit as an inverse function of speed. The sensitivity of the heading keeping circuit is adjusted in accordance with a signal from an automatic gain control circuit which derives a performance index J from ship's speed, heading error and rudder order signals occurring during a given measurement interval. The performance index derived during a given measurement interval is compared with the index derived in the previous interval and a counter register is set according to the results of this comparison. The heading keeping circuit receives heading error signals which are processed in a first proportional channel and also differentiated and processed in a second or rate channel. The attenuation in each channel is adjusted in accordance with the value stored in the counter register. The attenuation in the rate channel is made equal to the square root of the attenuation in the proportional channel. The modified rate and proportional signals are added to obtain the final rudder order signal.

Patent ES-483893-A1 (ES)
Title: Electro-optical control to detect filament passing through a guide-eye
IPC: B65H63/06
Filed: 1979-09-04
Abstract: Electro-optical sensor for the detection of a filamentary material (31) passing through a guide-eye (29). Prior detection devices required the filament to be continuously within the focus of the sensor. Thus, making it necessary to either flood the filament detection area with light or force the filament into the detection area. The present invention requires only that the filament is within the focus of the sensor with a frequency high enough to ensure a timely response in the event of a break. Thus, it can use a low power solid state light source (11) and a sensor (5) with a narrow area of focus (15).

Patent ES-8106804-A1 (ES)
Title: Apparatus for inspecting translucent articles for faults.
IPC: G01N21/90
Filed: 1980-02-19
Abstract: This invention concerns an apparatus for detecting the presence of faults in a translucent container of the kind comprising a scanning zone in which a translucent container is rotated while being repeatedly scanned by a spot beam of light in a direction parallel to the axis of rotation of the container, a light collection apparatus being arranged to receive light from the beam after passing through the container. The light collection apparatus comprises a rectangular matrix of photosensitive devices disposed behind a light-diffusing screen upon whose front surface the light from the scanning beam falls after passing through the container. A rectangular grid of thin white walls is sandwiched between the screen and the photosensitive devices so as to define a plurality of boxes with a respective device being located at the rear of each box. The grid thus effectively divides the screen into a large number of elemental areas and provides that each device receives light substantially only from a respective elemental area of the screen. This invention permits the detection of certain nonocclusive refraction faults in the translucent container by selective examination of the device outputs, as well as the detection of occlusive faults by measurement of the total light falling on the screen.

Patent ES-8104151-A1 (ES)
Title: Electric forehearth and method of melting therein
IPC: C03B7/07
Filed: 1980-06-03
Abstract: Disclosed is a method and apparatus for preventing the formation of blisters in an electrically-heated forehearth that utilizes submerged electrodes connected to either a single or plural phase alternating current source. The electrodes are arranged so that Joule effect heating is effected by passing alternating current through the molten glass with the center tap of the secondary of the power transformer being connected to the positive side of a Direct Current source through a filter, while the negative side of the DC source is connected to a counter electrode, immersed in the glass at a point upstream of the forehearth. With this physical arrangement, the formation of blisters due to free electrons migrating to and collecting on some of the electrodes that are at different potentials than the others is prevented. This is accomplished by the fact that all of the forehearth electrodes are maintained at the same potential and the counter electrode is at a different potential so that these free electrons will collect at the single counter electrode and create bubbles or blisters at a position well in advance of the forehearth. With this system, the blisters will disappear before reaching the forehearth. The forehearth electrodes are disclosed as being formed of stainless steel with molybdenum tips and the electrode support being electrically isolated from the forehearth structure.

Patent ES-8303622-A1 (ES)
Title: Compressor with cooling unit
IPC: F04C29/02
Filed: 1981-11-13
Abstract: A rotary compressor with forced displacement compresses a mixture of a gas and a cooling liquid which is intended to absorb heat generated by the compression working cycle. A cooling unit comprises separate heat exchangers for cooling of the compressed gas and the cooling liquid and a centrifugal fan which draws the cooling air through the heat exchangers. Due to the fact that the cooling air is drawn in through the heat exchangers a uniform air flow is achieved so that the heat exchangers can function with a high degree of efficiency and the centrifugal fan generates a pressure which is sufficient to deliver the heated cooling air to a point remote from the compressor. This release of the dissipated heat at a remote point increases the efficiency of the compressor because this prevents heated cooling air from mixing with the air drawn into the compressor. In addition it increases the efficiency of the heat exchangers. The waste heat can be recovered by leading it to a point where the heated cooling air can be used for room heating or process heating purposes.
