This approach generally pertains to a header connector with rigid latches. Also disclosed is a process for preparing aldehydes with variable normal- to iso-aldehyde ratios comprising contacting an olefin, hydrogen, and carbon monoxide with one or more phosphonite ligands, rhodium, and a hydroformylation solvent. Data writing is resumed upon detection of the fact that an amount of data equivalent to data writing capacity has been stored in the buffer memory. Signals from the various sensors are supplied to a controller, which provides signals to status indicators, and also operates to provide alarm signals via network interfaces to remote locations.
