Patent ES-435478-A1 (ES)
Title: Anti-sway system for a spreader suspended from a crane
IPC: B66C1/00
Filed: 1975-03-10
Abstract: An apparatus for arresting the pendulums and rotational sway motion of a suspended load relative to its lifting platform and utilizing a compensated reeving system. Rope drums are mounted on the ends of a shaft which is rotatably secured to a lifting spreader having a load attached thereto. Wire ropes are reelable from the rope drums and are secured at their ends to a feeder reel mounted on the lifting platform. Unreeling of the ropes from the drums due to sway of the load causes work to be done on a brake engaged with the shaft. The feeder reel gathers in and pays out the wire rope as the load is raised and lowered.

Title: Method and apparatus for detecting yarn on rods and severing the yarn
IPC: B65H63/00
Filed: 1976-06-30
Abstract: To prevent undesirable yarn lays from being wound on a roller (2), light emitted by a light source (1) is directed onto a point at the roller surface. A photosensitive device (3) is arranged in such a way that it receives the light reflected from the said point of the roller. When undesirable yarn lays are located at the said point on the roller, the light is reflected in a scattered manner, and the intensity of the light entering the photosensitive device is greatly reduced. When this is so, the device generates an output signal which is used for controlling a yarn cut-off device.

Patent ES-477129-A1 (ES)
Title: Devices and processes for determining properties of viscous fluids
IPC: G01N11/00
Filed: 1979-01-24
Abstract: Testing of rheological properties of a fluid is performed between a pair of members having cooperating faces, each characterized by minute, randomly interspersed land portions and cavity portions. The land portions of each face are planar and are disposed geometrically in a common plane. The cavity portions are irregular and are disposed in a network subordinate to the common plane. Testing involves the steps of placing a sample of the fluid between the cooperating faces, pressing the cooperating faces into flush contact with each other, and pulling the cooperating faces from each other. The force required for rupture of the fluid within itself, without first breaking its contact with the cooperating faces, is a function of the shear stress, yield point and other rheological properties of the fluid.

Patent ES-8104675-A1 (ES)
Title: Commutating capacitor charge detection circuit and method
IPC: H02M7/515
Filed: 1980-04-10
Abstract: A circuit and method is disclosed for detecting the presence of charges of appropriate magnitude and polarity on commutating capacitors of an inverter that converts a DC output current to a drive current of variable magnitude and frequency for driving an AC electric motor producing controllable rotation and torque. The presence of charges of appropriate magnitude and polarity is detected by measuring the voltages across the conduction controlled rectifying devices in the inverter. In addition, the existence of conduction controlled rectifying devices in the conducting state is determined by measuring the magnitude of the DC output current. An output signal is generated when the charges of appropriate magnitude and polarity are detected, which output signal is effective to allow the inverter to generate normal drive current. The absence of the output signal is effective to force the magnitude of the DC output current below a predetermined magnitude value and is effective to prevent the sequencing of gating signals to the inverter, whereby the drive current is such that the motor produces substantially zero rotation at substantially zero torque.

Title: Method and apparatus for communicating digital information words by error-correction encoding
IPC: H03M13/27
Filed: 1980-10-08
Abstract: A method and appratus are provided for communicating a sequence of digital information words. The information words are separated into a sequence of odd information words and a sequence of even information words. The separated odd and even information words are time-displaced from each other by a predetermined amount. The odd information words are encoded in an error-correcting code, and the even information words are separately encoded in a similar error-correcting code. The encoded time-displaced odd and even information words are combined into a transmission block, and this transmission block is transmitted or recorded. In one embodiment, the information words are encoded by generating an error-correcting word in response to the odd information words and by generating an error-correcting word in response to the even information words. The respective error-correcting words are interleaved with the odd and even information words. To recover the original information words, the transmission block is received and the odd and even information words are decoded so as to correct errors therein. The time displacement between the decoded off and even information words are removed. If an information word contains an uncorrected error therein, a correct information word is approximated therefor by interpolating adjacent decoded odd or even information words so as to approximate a correct even or odd information word, respectively. A corrected sequence of information words formed of the decoded and approximated information words is recovered.
