  • Patent number: 9856896
    Abstract: A cable lock and seal device with features preventing the locking mechanism from engaging the cable fibers too tightly to cut or fray is disclosed. A conventional device is made up of a body (10) and a cover (20) halves to complementarily form a block enclosing therewithin a passage (30) and a chamber (50). The body (10) is integrally formed with an anchor block (12) in which one end of a cable (14) is anchored. The other free end of the cable (14) may be inserted into the passage (30) which is preferably curved upward in traversing the assembled body-and-cover block. The chamber (50) is adapted with a ramp (52) rising towards the passage (30), a slot (54) for retaining a spring (56) which second end is disposed to urge a locking wheel (53) up the ramp (52) against the passage (30).

    Abstract: A cable lock and seal device comprising a body and a cover with which complementarily forms a block enclosing there within a passage and a chamber. The body is integral with a base in which one end of a cable may be secured. The other free end of the cable may be inserted into the passage which is preferably curved and traverses the assembled body-and-cover block. The chamber is adapted with a ramp rising towards the passage, a slot for retaining a spring which second end is disposed to urge a locking wheel up the ramp against said passage. The urging of the locking wheel by the biasing means up the ramp is restrained when the locking wheel's axle engages a rib on the chamber wall to limit the wheel's further entry into the passage upon sufficiently engaging said cable and preventing its withdrawal by reversing its insertion.

  • Patent number: 8808977
    Abstract: The present invention relates to a method for illuminating the viruses in a circulatory blood, comprising the following steps of: 1) Adding an anticoagulant into a whole blood source and establishing a circulation system for the whole blood source; 2) Withdrawing the whole blood with the anticoagulant into a plasma-separating device for a separation, when finished, directly pumping the red-blood cells back into the whole blood source and transporting the plasma into a mixing transport pump after the separation; 3) Meanwhile, pumping a photosensitizer methylene blue into the mixing transport pump so that the methylene blue is mixed with the plasma and pumped together into a plasma container; 4) Using an illumination device to illuminate the plasma in the plasma container for virus illumination, and pumping the virus-illuminated plasma into a removing device for removing off the photosensitizer; 5) The methylene blue being absorbed by the removing device and the plasma illuminated being transfused back into the

  • Patent number: 6950266
    Abstract: A micro-actuator is comprised of a piezoelectric motor mounted on a flexure tongue with offsetting hinges, to perform a fine positioning of the magnetic read/write head. The substantial gain in the frequency response greatly improves the performance and accuracy of the track-follow control for fine positioning. The simplicity of the enhanced micro-actuator design results in a manufacturing efficiency that enables a high-volume, low-cost production. The micro-actuator is interposed between a flexure tongue and a slider to perform an active control of the fly height of the magnetic read/write head. The induced slider crown and camber are used to compensate for thermal expansion of the magnetic read/write head, which causes the slider to be displaced at an unintended fly height position relative to the surface of the magnetic recording disk. The enhanced micro-actuator design results in reduced altitude sensitivity, ABS tolerances, and reduced stiction.
