Abstract: An electronic device displays a messaging user interface of a message application, including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and a first message region that includes a current version of a first message in the messaging session. The conversation transcript includes an indication that the current version of the first message is a revised version of the first message in the conversation transcript. In response to detecting an input that corresponds to a request to see versions of the first message, the electronic device displays a versions user interface that includes the current version of the first message and one or more prior versions of the first message.

Abstract: A method and object-oriented architecture for interfacing a user to a relational database system The contour of the interface is defined by a profile object and a task object. The profile object, in response to user selection, defines one of multiple role objects with associated user proficiency and system behavioral characteristics. The task object responds to parameters derived from the profile object to generating a query for the relational database system. In one form, the task object includes one or more functional objects suitable to query the database. Representative functional objects are the domain object (used to formulate problem oriented queries), the analysis object (used to analyze the data extracted from the database), the report object (used to generate a user response format), and the link object (used to relate the components within the task object).

Abstract: An improved chemical feeder employing periodic partial immersion in a forced circulation system is provided having a soluble chemical hopper, and a dissolving chamber into which the soluble chemical chamber extends an adjustable distance and a discharge chamber in fluid flow communication with the dissolving chamber to selectively receive chemically treated water from the dissolving chamber and discharge it into a flow loop connected to the forced circulation system. A visual indicator ring is preferably present to show the height of the hopper. The adjustable hopper allows an expanded range of chemical feed rates for the feeder.

Abstract: A solid calcium hypochlorite composition contains calcium hypochlorite and an alkali metal salt of phosphonobutane polycarboxylic acid having an available chlorine concentration of at least 50 percent by weight.It has been found that the use of the novel compositions of the present invention can significantly reduce scale formation in dispensers for calcium hypochlorite particularly where water having high total alkalinity is used. The prevention or inhibition of scale formation is accomplished without harmfully affecting other properties of the pool water such as the pH.

Abstract: A solid calcium hypochlorite composition contains hydrated calcium hypochlorite and an alkali metal salt of phosphonobutane polycarboxylic acid having an available chlorine concentration of at least 50 percent by weight and a water content of at least 4 percent by weight.It has been found that the use of the novel compositions of the present invention can significantly reduce scale formation in dispensers for calcium hypochlorite particularly where water having high total alkalinity is used. The prevention or inhibition of scale formation is accomplished without harmfully affecting other properties of the pool water such as the pH.

Abstract: A method of managing body and footnote text during preparation, review, editing, and printing of a document. Preparation can be accomplished in a one pass input keying operation without regard to (1) storage of the body and footnote text, and (2) numbering of reference points in the body text and corresponding footnotes. During preparation there is separate storage of the body and footnote text, separate display frames are provided for each, editing is permitted in the frame being operated on, and the system automatically numbers and updates the numbering of the reference points and footnotes. For a review of the appearance of the document in its to-be-printed format, and any editing thereof, the body and footnote text are assembled for display. Thereafter, the document can be printed.

Abstract: A method of, and system for, designating footnotes and footnote references based on, and beginning with, an operator defined initial designation. The initial designation can be made up of both a variable functional portion and an accompanying fixed aesthetic portion. The functional portion is for numbering and can be either a numeric or other graphic character. The fixed portion can be both cosmetic and functional and can be made up of a character or characters. The designation can be located either on-line or in an indexed position. When numeric characters are used in number designating footnotes and footnote references, there is an incrementing by one of the operator selected initial number for each succeeding footnote and footnote reference designated. When other graphic characters are used in number designating footnotes and footnote references, the number of graphic characters is increased by one for each succeeding footnote and footnote reference designated.

Abstract: A method for editing data stored in a word processing system in table entry format. Means are provided for operator selection and definition of a top reference area for displaying table column headings or a side reference area for displaying table row entry headings, or both. A vertical separator column of video-reverse spaces separates the display screen into left and right viewports, when a side reference is defined. A horizontal separator bar of video-reverse spaces separates the display screen into top and bottom viewpoints when a top reference is defined. Means are also provided for scrolling the displayed side reference area headings in synchronism with the scrolling of the editable portion of the table, and segmenting the top reference area headings in synchronism with the segmenting of the portion of the editable table entries.
