Abstract: An electronic calendaring method for use in a data processing system which includes a plurality of interactive terminals which are interconnected to permit an end user at each terminal to interchange information with each other and to maintain an electronic calendar. The method facilitates the reply process to an electronic invitation to attend a meeting that is issued by one of the end users by arranging for the system to advise the invitee that a meeting notice is available to review in the "In Box" of the terminal. The method causes a composite screen to be built which simultaneously displays the meeting details and the relevant section, i.e. a day of entries, of the owner's calendar in a side by side format so that calendar entries are correlated to the meeting data and time. The composite display permits an interactive selection by the calendar owner end user of at least one option which can be either to accept the invitation and calendar the meeting or to reject the invitation.

Abstract: A dye laser fluid dye solution replenishment system in which the portion of the lasing fluid passing through the laser head which has been activated to a lasing condition is separated from the remainder of the unactivated dye solution and is separately restored before being recombined into the fluid flow path. The thus separated and degraded dye solution, representing only the degraded component of the flowing dye solution, is filtered to remove the degradation products and restored to the desired dye solution component concentrations. The thus restored solution is reinserted into the fluid flow path through the laser head.

Abstract: A removable orthodontic appliance is firmly seated on the teeth on each side at a midregion by clasps which provide a base for a label filament serving as a reference arch, and curved lingual spring filament which urges the teeth against the reference. The lingual filament provides a gentle but constant force over a substantial distance to cause repositioning of selected teeth without the need for frequent readjustments. The mountings for the filaments comprise open loops having filament receiving sleeves at each end by means of which the positions and angles of the filaments may be adjusted but the filaments may be coupled in solely by mechanical means. The lingual filament may comprise a memory alloy having a temperature transition below normal body temperature so that it may initially follow the irregular profile of the teeth and continue to exert pressure over a substantial distance as the teeth are repositioned.
