Inventor: GUZZINI VIRGILIO
IPC: H02H1/00
Filed: 1990-12-20
Abstract: A safety device (10) comprises cutout means (23, 24) for automatically disconnecting an electrical appliance (11) from the power line (12, 13) supplying power to it. An electric signal generator (19) and a detector (21) of said electric signal are connected in series with the interposition of coupling transformers (17 and 18). The series is connected, with condensers (15, 16), between the conductors (12, 13) of the power line and the earth connection (14) of the appliance (11), so that the path of the signal between the generator (19) and the detector (21) is substantially closed by the electrical impedance between the earth connection (14) and the earth reference (26) of the source of power (25). 
     When the incoming signal to the detector is of an amplitude smaller than a predetermined value, the signal detector (21) commands the cutout means (23, 24) to disconnect the appliance (11) from the power line (12, 13).

Abstract: In an AC to DC power conversion circuit including a boost inductor (24) connected in series between a full-wave rectifier (18) and a DC load (12), a switch (38) is connected to selectively shunt boost inductor current from the load. Switch conduction is controlled by a pulse width modulator (62) generating switching pulses at a high fixed frequency. The pulse widths are automatically varied as a function of boost inductor current (44,42), load voltage (48,50), and an ideal sinusoidal waveform derived (54) from the AC input voltage to force the boost inductor current to closely conform to the ideal sinusoidal waveform and thus minimize harmonic distortion, while achieving load voltage regulation and near unity power factor.

Abstract: First, levoglucosenone is made to react with methyl lithium in the presence of copper iodide in order to introduce a methyl group into an enone group of levoglucosenone, and to obtain 1,6-anhydro-3, 4-dideoxy-4-C-methyl-β-D-erythro-hexopyranose-2-ulose. This methyl compound is oxidized in acetic acid for lactone formation, and (3S,4S)-5-hydroxy-3-methylpentan-4-olide is thus obtained. Further, this lactone is made to react with tosyl chloride in anhydrous pyridine to obtain (3S,4S)-3-methyl-5-tosyloxypentan-4-olide (tosylate). The obtained tosylate is alkylated with n-propyl lithium in the presence of copper iodide to obtain (3S,4R)-3-methyl-4-octanolide. Here, the (3S,4S)-3-methyl-5-tosyloxypentan-4-olide may be treated with potassium carbonate to cleave lactone ring once, thereby obtaining epoxide. After that, the obtained epoxide is alkylated to form lactone ring again to obtain (3S,4R)-3-methyl-4-octanolide.
