    摘要： An auxiliary dialing system for a mobile telephone of the type having a handset coupled with a radio transceiver by a data transmission line comprises a data process and control module having a microprocessor and data storage devices. The data process and control module includes a key pad for entering data into the data storage devices and a display for displaying data entered from the keyboard and retrieved from the data storage devices. The data process and control module is connected to an interface module which is in turn spliced into the data transmission line between the handset and the radio transceiver. The interface module insures that when a telephone number is transmitted from the data process and control module to the transceiver, the data is placed on the data transmission line in such a way that it does not interfere with or corrupt data being transmitted from the handset to the transceiver and vice versa in normal operation of the mobile telephone. Telephone number may thus be automatically dialed by the data process and control means by transmitting the numbers to the radio transceiver through the interface module so that the radio transceiver places the telephone call as if it had been dialed from the handset.

    摘要： A phase inversion process for the preparation of cellulose triacetate (CTA) and regenerated cellulose membranes is disclosed. Such membranes are useful as supports for liquid membranes in facilitated transport processes, as microfiltration membranes, as dialysis or ultrafiltration membranes, and for the preparation of ion-selective electrodes. The process comprises the steps of preparing a casting solution of CTA in a solvent comprising a mixture of cyclohexanone and methylene chloride, casting a film from the casting solution, and immersing the cast film in a methanol bath. The resulting CTA membrane may then be hydrolyzed to regenerated cellulose using conventional techniques.
