  • Recovery and purification of B-phycoerythrin produced by using two-aqueous-phase systems and isoelectric precipitation
    Patent number: 8178321
    Abstract: This invention focuses on a novel process in which Porphyridium cruentum biomass first undergoes a stage of cellular disruption and subsequently stages of recovery and purification in order to achieve the purified B-phycoerythin (BFE) protein dye, using isoelectric precipitation and two-aqueous-phase systems. The steps of recovery and purification include isoelectric precipitation followed by a step of liquid/liquid extraction by means of two-aqueous-phase systems that use polyethylene glycol (PEG) and phosphate salts. The BFE protein dye obtained in the two-aqueous-phase extraction step undergoes an ultrafiltration step in order to remove the polymer (PEG) and to obtain a dye with a purity greater than 4.0 defined as the relationship between the absorbencies at 545 and 280 nm (BFE purity=Abs 545 nm/Abs 280 nm).

  • Probe actuated bottle cap and liner
    Patent number: 8172102
    Abstract: A cap for use with bottled water dispensing systems. The cap includes a main cap and a liner. The main cap has an opening which receives and seals against a probe. The liner is gripped between the main cap and the bottle neck and has a outside part and an inner movable part. The inner movable part is linked to the outer part by a large connecting section that serves as a hinge, and breakable or frangible connecting section. When the bottle is lowered onto the dispensing system, the probe enters into the opening in the main cap, breaks the frangible connection, and pushes the inner movable part open like a flap. The liner, at the location of the large connecting section, is resilient such that the inner movable part tends to close when the bottle is removed from the dispensing system.

  • Tone signal detector, tone signal detection method, and computer readable recording medium
    Patent number: 8170198
    Abstract: Upon selection of the frequency of a tone signal, a local oscillator generates a frequency signal having a shift frequency corresponding to the frequency of this tone signal. A frequency shifter generates a frequency-converted signal by shifting a frequency of the tone signal by a shift frequency of the frequency signal generated by the local oscillator. A BPF removes an image signal from the frequency-converted signal which the frequency shifter generated, and a normalizer normalizes the amplitude of the signal output from the second BPF. By this, even if the amplitude of the tone signal is small, the amplitude thereof is unified to a suitable magnitude. For this reason, even if there is a difference in the amplitude of the tone signal, the tone signal can be detected reliably and an false detection can be prevented.
