Title: Procedimento e mezzi per provvedere gli aspiratori a filtro liquido di almeno due barriere addizionali di filtrazione
Inventor: SOZZI VALIDIO
IPC: A47L9/18
Filed: 1994-07-15
Granted: 1997-07-15
Abstract: Il procedimento per incrementare il rendimento degli aspiratori a filtro liquido, consiste nel provvedere almeno due barriere addizionali di filtrazione mediante le quali l'ambiente liquido (10-11) e l'ambiente (01) aeriforme vengono materialmente separati da almeno un'interfaccia (5), avente una superficie sospesa sopra il liquido e coprente una parte preponderante della superficie superiore di esso. Essa esercita una leggera pressione sul pelo (11') libero del liquido (11), tale da limitare l'ebollizione da tale superficie coperta e obbliga le bolle di aria a seguire un percorso molto più lungo e quindi a frazionarsi. Detta interfaccia (5) rappresenta la base di un recipiente (5'), che si eleva ad incontrare un coperchio (6) a comignolo rovescio. La corrente d'aria di ebollizione ascende all'esterno della colonna (50), e giunta all'apice, viene costretta, dopo un percorso centripeto tortuoso, a passare, attraverso un filtro (8) fatto di materiale imputrescibile.

Title: An enzyme-capture assay for the rapid identification of escherichia coli in blood cultures
Inventor: HWANG SHIOW-WENN
IPC: C12Q1/04
Filed: 1994-01-17
Granted: 1997-08-01
Abstract: This invention describes an enzyme-capture assay (ECA) for rapid identification of Escherichia coli in blood cultures using (beta)-D-glucuronidase as a marker of E. coli. Microtiter plate coated with anti-glucuronidase was used to capture the enzyme from the cell lysate of a blood culture which showed growth of gram-negative bacteria. The assay using 4-methylumbelliferyl-(beta)-D-glucuronide as a fluorogenic substrate had a detection limit of 0.1 ng/ml (3 x 10-13 M) of the enzyme; this was approximately equal to a cell concentration of 1000000 CFU/ml of E. coli. Of 212 blood cultures showed growth of gram-negative bacteria, 77 specimens were found to contain E. coli by the conventional culture procedures, and 73 samples were positive by the ECA. Among the 135 blood cultures from which E. coli was not isolated, ECA gave one false-positive (Salmonella enterititis) reaction. Thus, the sensitivity and specificity for the identification of E. coli in blood cultures by ECA were 94.8% (73/77) and 99.3% (134/135), respectively. From the finding of gram-negative bacteria in the culture bottle, the assay can be completed within 4 h. In addition, among four (beta)-D-glucuronides tested, p-nitrophenyl-(beta)-D-glucuronide was found to be the best inducer of (beta)-D-glucuronidase. In view of the high isolation rate of E. coli from bacteremic patients, the test can be performed in parallel with the conventional culture protocols; this may shorten the identification time of E. coli and proper antimicrobial treatments can be started 24 h earlier than the conventional identification systems.

Title: In-line predistorter for linearization of electronic and optical signals
Inventor: HENRY A BLAUVELT
IPC: H03F1/32
Filed: 1995-06-12
Granted: 1996-01-01
Abstract: An electronic circuit provides a linear output from a nonlinear transmission device such as a laser. Second and higher order distortion of the nonlinear device is compensated by applying a predistorted signal equal in magnitude and opposite in sign to the real and imaginary components of distortion produced by the nonlinear device. The input signal for the nonlinear device is applied to an in-line electrical path coupled to the nonlinear device. The in-line path contains at least one component for generating primarily real components of distortion. In some applications, at least one component for generating imaginary components of distortion is located on the in-line path. Filter stages are used to provide frequency dependent predistortion. In a preferred embodiment, an attenuator, a MMIC amplifier, a CATV hybrid amplifier, and a varactor in line with a semiconductor laser, provide the predistorted signal. In another embodiment, the real component of predistortion is generated by a FET configured as a voltage controlled resistor. In still another embodiment, the real component of predistortion is generated by the parallel combination of a diode and a resistor connected in series with the RF signal path. Also provided is a separate circuit including antiparallel diodes and reactive elements for generating frequency dependent third-order predistortion.
