Abstract: A telephone call responding system which allows the user to respond to an incoming telephone call without actually speaking to the caller personally, and, if desired, without having to pick up the telephone to answer a call. To activate the responder system, the user, upon receiving an incoming telephone call, selects one of a plurality of call response messages by actuating a control key of the responder system corresponding to the desired message. Once activated, the responder system connects itself to the telephone line and, utilizing speech synthesis or digital-to-analog conversion, delivers the selected message for putting-off an unwanted or nuisance call, asking the caller to call back later, or instructing a person on an extension telephone to hang up. After delivering the message, the responder system disconnects itself from the telephone line until once again activated by the user.

Abstract: Automatic orientation of predefined chemical structures in conjunction with a computer terminal employs respective protocols corresponding to a system state. The system states can include a chain state, ring state, library state, and retrieve state. Upon orientation, the object is attached according to a specified attachment command to a parent graph. The protocols corresponding to connection of the object to the parent includes rules regarding angles at which the structures can be attached to one another, and another protocol governs rules respecting rotation of the stored object through predetermined angles. Nodes of the object recalled are automatically provided with markers in alphabetic order from the most recently used marker corresponding to a letter of alphabet. Multiple alphabet sequences are used. Specification of position is indicated by inputting the lower case letter of the alphabet corresponding to the location desired. Bonds can be specified between two markers.
