Abstract: Abstract of the disclosure:            Process for reducing the content of primary and secondary amine in a tertiary amine A process  is  described  for  reducing the  content of primary and secondary amine in a tertiary amine in which the tertiary amine to be treated is brought into contact with an organic anhydride until the reduction sought in the content of primary and secondary amine is achieved. Bringing the compounds into contact as mentioned, which as a rule is carried out at a temperature of 20 to 200°C, results in the formation, from the primary amine and the secondary amine, which is particularly undesirable, of the compounds acid and/or acid amide. After removal of these compounds,  which are comparatively harmless,  a completely pure tertiary amine is present.

Patent CA-2065331-A1 (CA)
Inventor: MOORE MORRIS A
IPC: H04M1/73
Filed: 1990-08-13
Abstract: A power saving method and apparatus in a time division multiplexed system (10) capable of providing a synchronous full duplex communication between a telephone network (12) and a plurality of remote communication units (18). A communication resource controller (14) provides system synchronization, by periodically transmitting synchronization messages through one or more remote sites (11). The communication units (18) attempt to acquire synchronization during a synchronization acquisition in-terval. If synchronization is acquired, the communication units (18) enter a synchronous battery saving mode (515). In the syn-chronous battery saving mode (515), the communication units (18) can detect a call request either to their own address or to the address of another communication unit. If no call request is detected, the communication units (18) reduce power consumption for a synchronous power saving time interval, and thereafter merely verify synchronization. However, if synchronization is not acquired, the communication units enter an asynchronous power saving mode (525), wherein they reduce power consumption for an asynchronous power saving interval.
