Abstract: TAB ADJUST FUNCTION FOR AN ELECTRONIC TYPEWRITER                        ABSTRACT            A typewriter may store a document in a first format with margins and tab stop locations defined for a first format and then the operator may change the margin or tabs to a second format.  The operator may also select whether the tab stop locations may played out with the same relative positioning to the left margin or be played out using the newly set tabs and margin setting. The newly set tab stop locations are defined as a fixed position relative to the print line and are independent of the left margin position or the position of the original tab stop location relative to the left margin.            The memory of the typewriter may be optionally updated when the document is played out using the second format tab stop locations, if the operator conditions the storage to accept changes during playout. Alternatively, the document may be played out using the second format tab stop locations, and the original format tab stop maintained for future use.

Title: Multi-stage opacifying polymer particles containing non-polymeric acid absorbed therein
Inventor: KOWALSKI ALEXANDER
IPC: C09D7/65
Filed: 1989-05-08
Granted: 1992-06-16
Abstract: ABSTRACT          Multi-stage polymer particles containing one or more void space(s) therein are produced by sequential emulsion polymerization of an essentially low-acid earlier polymer stage, encapsulation of said low-acid polymer stage with at least a final polymer stage, contacting said polymer particles with a non-polymeric carboxylic acid to permit the acid to be absorbed into said low-acid polymer stage and swelling the polymer particles by contacting the particles with an aqueous base.  The low-acid polymer stage is formed by emulsion polymerizing a monomer system comprising ethylenically unsaturated monomer(s) and containing less than 5% by weight of monomer(s) eontaining acid functionality.  The low-acid polymer stage is subsequently encapsulated by one or more polymer stages by emulsion polymerizing ethylenically unsaturated monomer(s) in the presence of the low-acid polymer stage.  The final stage has a glass transition temperature (Tg) of about 50°C or greater, and the total polymer stages having a Tg of about 50°C or greater comprise about 60% or more by weight of the polymer particles.  A non-polymeric carboxylic acid is absorbed into the polymer particles and the resultant particles are contacted with base at a pH sufficient to swell the particles with water at a temperature near or above the Tg of the neat polymer or plasticized polymer of the final polymer stage.  When dried the particles contain void space(s) therein which produce(s) opacity in compositions in which the particles are contained.

Abstract: SYSTEM FOR SCANNING DOCUMENTS  WITHOUT LOSS OF IMAGE DATA                       Abstract A document processing system directs documents at a high rate of speed past an optical scanner which captures written information on the documents as video image data.  The video image data is directed over a data channel to a host computer system where the data is stored on a mass data storage device for subsequent retrieval.  A buffer is provided between the scanner and the data channel, which receives data a rate which varies in relation to the amount of information present on the documents.  Data is extracted from the buffer at a rate which is limited by the host computers channel transfer rate.  A control means is associated with the buffer and is operable for controlling a hierarchy of actions ranging from slowing down the incoming data stream to stopping the data stream altogether in order to prevent any loss of video image data due to overfilling of the buffer.
