Abstract: A method and system are provided for rendering a brush stroke with multiple nibs which are added to a centre point indicated by a cursor, and the position and movement of each nib are controlled based on variables which can be set by a user. The variables include a number of nibs to be rendered in the brush stroke, initial position values determining an initial position of each nib relative to a centre point, and movement variables representative of movement of each nib relative to the centre point. A current position of the centre point is determined relative to the document. A new position for each nib is calculated, relative to the current position of the centre point, based on the initial position values and the movement variables. A dab is rendered at the new position of each nib. By repeating the steps of determining a current position, calculating a new position and rendering a dab while the centre point is being moved, a brush stroke of unique painting effect is rendered.

Abstract: The invention is a method and system for determining an address from a print buffer stream. The method begins with initializing an address detection and determination routine, and then directing a print buffer stream to be read by the address detection and determination routine. In reading the print stream data, the application tokenizes address data resident in the print stream before comparing the tokenized data with data tables wherein each of the data tables comprises address characteristics. In making the comparison of the tokenized address data, the method then determines whether or not the tokenized address data matches a format in one of the data tables. If a match is found, then the method applies a coding scheme to the matched data. The coding scheme being determined in accordance with the matched data's corresponding data table. Matched data is coded in accordance with the coding scheme to create a coded address. If a match can not be determined, then the tokenized data is placed in a memory of the addressing system for subsequent analysis or use. Each of the data tables within the system further comprise data establishing a definition of a particular address description based on carrier requirements. Address description is further defined by country specific address requirements; which in turn further comprise: linking files for use by an addressing software application to link an applicable data table with the application for the purpose of parsing address data based upon requirements resident in the data tables; barcoding requirements; and, postal zone requirements, if any, for postal coding.

Title: Extruder die head
Inventor: BECKMANN HANS-UDO
IPC: B29C48/10
Filed: 2000-05-18
Granted: 2007-01-23
Abstract: An extruder die head comprises an internal cylindrical mandrel and a shell, which encloses the mandrel concentrically. Between the mandrel and shell an annular channel is formed, which is connected to an annular die slit. A polymer melt is fed through a line to the annular channel. To prevent the polymer melt in the area of the start of the annular channel from penetrating into any spaces that form between the mandrel and the shell due to differential thermal expansion, a ring is located between the mandrel and the shell. The material of the ring is chosen to have a coefficient of thermal expansion such that when the die head is heated up due to the polymer melt, the ring seals any spaces between the shell and the mandrel. In an alternative arrangement, the materials of the mandrel and the shell are chosen such that the seat, which connects the mandrel to the shell and is located below the annular channel, becomes more tightly sealed on heating.
