摘要:
A control circuit for a continuous conversion of information carrying anaous voltage and current signals into digital magnitudes containing said information, the respective digital magnitude is so coded that always one digital magnitude differs from the next higher digital magnitude merely by a one-digit digital information value. The circuit of the invention is characterized primarily in that for a simultaneous reception of the signals there are provided one or more serially arranged analogous digital converters as well as control stages comprising one or more groups, while the groups for folding the signals are formed by differential converters which emit the folded signals at the exit of the respective group and while an analogous digital converter follows the control stage or stages. The analogous digital converter forms informational values of the digital magnitudes by a subdivision of the signals.

A circuit arrangement for dividing an input signal A by a signal B, for eple for use in localizing radiation detection, has a dividing analog-to-digital converter receiving an addition signal A+q.times.B as well as the divisor signal B to form the quotient (A+q.times.B)/B from which a digital random value r is subtracted, where r corresponds to q. The ADC can be a Flash ADC and the resulting circuit has good differential linearity and is fast.

A gas turbine engine system includes a gas turbine engine using vaporized liquefied gas as fuel. The gas turbine engine is configured to ingest intake air from an intake port and direct exhaust gases to an exhaust port. The gas turbine engine system also includes a heat exchanger with a heat transfer fluid therein. The heat exchanger is configured to create at least a part of the fuel by heating the liquefied gas. The gas turbine engine system also includes an intake air temperature control circuit. The intake air temperature control circuit includes conduits configured to direct the heat transfer fluid to the intake port and the exhaust port. The gas turbine engine system also includes a control system configured to selectively direct the heat transfer fluid to one of the intake port and the exhaust port.

The invention relates to biaxially oriented polyester films which contain 0.1-5.0% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and 0.2-10% by weight (based on the weight of the film) of epoxidized fatty acid glycerides, the epoxidized fatty acid esters having a mean molecular weight of at least 425 g/mol. Such films find use in outdoor applications, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

The invention relates to a biaxially oriented film, predominantly formed from a polyester whose diol component includes at least 80 mol-% of 1,4-cyclohexanedimethanol (CHDM), and whose dicarboxylic acid component includes at least 80 mol-% of one or more benzenedicarboxylic acid(s) and/or one or more naphthalene dicarboxylic acid(s). The dicarboxylic acid component includes a main dicarboxylic acid component forming an at least 55 mol-% portion, chosen from either 2,6-naphthalene dicarboxylic acid or terephthalic acid. The dicarboxylic acid component further includes a secondary dicarboxylic acid component, present in an amount of at least 18 mol-%, with the secondary dicarboxylic acid component differing from the main dicarboxylic acid component. The invention further relates to a method for producing the film and its use.
