Title: System for fault detection and location on data lines
IPC: H04L1/22
Filed: 1972-11-30
Abstract: Whenever faults or errors are detected in the receive data signal at one station of a data link, a predetermined signal requesting transmission of a special signal is transmitted to the other station of the data link. If the special signal is not correctly received at the one station, a changeover occurs and the transmitter and receiver within each station are interconnected. Check signals are transmitted and from the results it can be determined whether the fault is due to bit errors, a faulty transmitter and/or a faulty receiver of either or both of the stations or a faulty line interconnecting the stations.

Patent ES-454569-A1 (ES)
Title: Clamp for regulating fluid flow through plastic tubing
IPC: A61M39/28
Filed: 1976-12-23
Abstract: Tubing through which fluid flow is to be regulated is placed in a regulating clamp wherein it is clamped between a roller wheel and a surface having a variable cross-sectional area channel extending therealong. This surface is parallel to the travel path of the wheel, and thus there is a constant separation distance between these two elements for all wheel positions. Flow rate through the tubing is changed by longitudinal adjustment of the position of the roller wheel, the ratio of the portion of the tubing which is clamped between the wheel and the surface to that which is not clamped and over the channel, thereby being varied. A plurality of ridge elements are formed in the surface and act to locally pinch or grip the tubing at discrete intervals, thereby substantially lessening creep of the plastic tubing which, in turn, minimizes the flow rate change once the clamp has been set for the desired rate of flow.

Patent ES-470362-A1 (ES)
Title: Bipolar transistor switching network crosspoint
IPC: H03K17/16
Filed: 1978-05-31
Abstract: A semiconductor switching network is disclosed in which complementary bipolar transistors are employed as "floating" crosspoints. Each crosspoint consists of a pair of complementary bipolar transistors with each transistor being connected in series with one of the leads of the communication pair. Each one of the complementary bipolar transistors is, in turn, surrounded by a "protective control shell" of diodes and transistors which provides the crosspoint with overvoltage and reverse voltage protection and secures crosspoint turn-off. Additionally, the protective control shell contains a self-bias arrangement to eliminate the need for external power supplies to operate the crosspoint as well as an optoisolator control circuit to eliminate direct connections to external control circuits. Thus, the disclosed "protective control shell" converts the complementary bipolar transistors into a "floating" crosspoint - powered solely from the communication leads with no direct connection to any external power supply or control circuit, which crosspoint is insensitive to both the polarity and the magnitude of the applied voltage and current.

Title: Method and apparatus for pipe inspection.
IPC: G01N27/90
Filed: 1980-05-08
Abstract: Casing inspection apparatus and method are disclosed for determining defects and other anomalies in ferromagnetic oil well casing. The inspection apparatus utilizes a pair of coaxial transmitter coils for generating an alternating magnetic field in the casing thereby inducing circumferential currents in the casing wall. These circumferential currents and the magnetic field associated with the currents are perturbed by corrosion, holes, and other anomalies both inside and outside the casing wall. Differential receiver coils are urged in proximity with the casing wall to generate a differential receiver signal in response to such perturbations in the magnetic field. The differential receivers are provided with three coils serially connected and having N, 2N and N winding turns respectively. The windings of the coils are disposed in adjacent relationship to one another and wound in a direction opposite to the adjacent winding. The casing inspection apparatus achieves enhanced sensitivity to small defects and reduced sensitivity to magnetic anomalies by processing both the amplitude and phase components of the receiver signal.

Patent ES-8105140-A1 (ES)
Title: Refrigerated display case having ambient air defrost
IPC: A47F3/04
Filed: 1980-06-20
Abstract: An open top refrigerated display case having an ambient air automatic defrost system and a method of operating such a case. A single air conduit extends in a U-shaped formation along opposing side walls and the bottom wall of the display case. The air conduit has openings at both ends in the location of the upper portions of the side walls. Arranged within the air conduit is at least one reversible fan and a set of refrigeration coils. During a refrigeration cycle the fan circulates air through the air conduit in a first direction towards the refrigeration coils. When frost buildup within the display case has reached a certain level, the system is switched to a defrost cycle. During the defrost cycle, the fan circulates the air in the opposite direction through the air conduit and draws in ambient air from outside of the display case. Since such ambient air is of a higher temperature than the normally refrigerated air, it serves to defrost the system. The ambient air, after passing over the evaporator coils and through the air conduit, is expelled from the air conduit in a direction towards the outer side of the refrigerated case and away from the interior of the case.

Patent ES-8201792-A1 (ES)
Title: Adaptive stylus translator
IPC: G11B21/08
Filed: 1980-10-17
Abstract: An adaptive eg video disc record stylus kicker (46) system for inducing limited pickup or stylus (14) translations radially across the disc record (12). Control circuitry (54) responsive to disc track and disc angular sector identification signals automatically calibrates the kicker activation signals (51) to produce a desired kicker induced stylus translation. That is, the control circuitry responsive to these track identification signals and to player commands (53) evaluates the error between actual kicker induced stylus translations and the programmed kicker induced stylus translations. A microprocessor (56) establishes a table containing kicker control signals for driving the kicker in each sector of the disc. For a given kicker induced stylus translation, the error is calculated between the actual stylus translation and the programmed stylus translation and the control signal for the respective sector is adjusted accordingly. Subsequently, the control signals for each of the other sectors are altered proportional to the adjustment made to the particular control signal in accordance with a correlation function. The system operates to correct mistracking (identification signals do not appear in the correct sequence) due, e.g. to record defects.
Patent ES-8201751-A1 (ES)
Title: Passive infrared intrusion detection system
IPC: G08B13/19
Filed: 1980-11-11
Abstract: The invention comprises a passive infrared intrusion detector including a lamp for locating the zones being protected by the detector. The detector includes a heat sensor, a lens system for receiving and focusing the body heat of an intruder on the heat sensor, and electrical circuitry responsive to the heat sensor for actuating an alarm or detection signal when the body heat of an intruder is detected. The zone locator lamp is positioned near the heat sensor and its light passes through a lens in the general direction of a zone to be protected. The light parallels a portion of radiation which is focused on the heat sensor by another lens. If the light can be observed from a given position in front of the detector, that position is in a zone being observed by the detector and body heat radiated from that zone will be focused on the heat sensor. Thus, zones protected by the intrusion detector can be established by adjusting the position of the detector until light from the zone locator lamp is observed. Once these zones are established, the lamp may be disconnected and the intrusion detector placed in the "ready" or "stand by" mode.
