  • Patent number: 5856539
    Abstract: It was found that the conversion (by isomerisation or branching) of unsaturated fatty acids into branched fatty acids can be catalysed by materials having a microporous structure. Such a process gives high conversion rates and a high selectivity towards branched fatty acids, whilst a low amount of undesired by-products is obtained. Zeolites are preferred materials for catalysing said reaction.

The circuit is connected to an alarm, maintains the alarm inoperable, and places the alarm in operable condition upon operation of the switch due to the first breath delivered to the patient.
