Title: Process for the continuous bulk production of high impact vinylaromatic (co)polymers
IPC: C08F279/02
Filed: 1990-05-23
Abstract: Described is a process for the continuous bulk production of 
high impact vinylaromatic copolymers in which a vinylaromatic 
monomer, an optional vinyl-cyanide comonomer, a rubber, a part 
of a diluent solvent and a catalyst are premixed at a tempera­
ture below 100°C and fed to an agitated tubular plug-flow 
reactor which is divided into several stages or zones. The 
excess mixture is recycled to the premixer and the remaining 
portion of the diluent solvent is injected in the top of the 
reactor to prevent the formation of incrustations. In the 
first zone of the reactor, the temperature and the residence 
time of the mixture are controlled so as to halve the catalyst 
lifetime.  
     The polymerization is continued in the subsequent zones of the 
reactor until at least 40% by weight of solids have been 
formed.

nucleus as growth point.

Title: Reduction of tannin stain on painted surfaces
IPC: C09D7/12
Filed: 1991-10-28
Abstract: Discoloration of surfaces, such as painted or treated wood surfaces, by tannin-staining caused by the complexing of certain transition metal ions with tannate ions (the process is often referred to in the art as "tannin-stain bleed") is reduced or prevented (eliminated) by contacting a transition metal ion on a painted surface or surface to be painted with a complexing agent for the transition metal ion, such as by the addition of the complexing agent for the transition-metal ion to paint formulations or by pretreatment of the wood surface with the complexing agent before painting. It is believed that the complexing agents form coordination complexes with transition-metal ions on the surface of and within the paint film, thus preventing the formation of highly-colored complexes of the transition metal ions with the tannate ions derived from the tannins in the wood. This technique is applicable to all woods and other surfaces susceptible to tannin-staining and especially to stain-susceptible woods such as redwood and cedar. Using appropriate formulation or application techniques, the method may be used with water-based or solvent-based paints.

Title: Method for producing gradient tonal representations and a printhead for producing the same
Inventor: WALLACE DAVID B
IPC: B41J2/045
Filed: 1995-06-06
Abstract: A method of producing, on a physical medium, a gradient tonal representation of an image and a printhead for producing the same. An input image is divided into first and second regions. First, continuously variable intensity level, continuous tone and second, discretely variable intensity level, half-tone portions of the representation which respectively correspond to the first and second regions of the image are then printed by depositing selected quantities of ink on the first and second portions of the physical medium such that each pixel thereof has an ink intensity level corresponding to the image intensity level for the corresponding one of the pixels of the first region of the image. The ink is deposited on the second portion of the physical medium by depositing a spot of ink having a first diameter on selected ones of the pixels of the second portion, depositing a spot of ink having a second diameter on others of the pixels of the second portion and depositing no ink on still others of the pixels of the second portion such that the second portion of the representation has the desired ink intensity level. The color of the ink ejected may be black, in which case, the gradient tonal representation produced thereby shall be a gray scale representation, or other color such as yellow, cyan or magenta. <MATH>

Abstract: The inventive methods employ symmetric encryption with first
and second keys to provide secure access to information
accessible to be shared among a dynamically changing set of
authorized users on a network having a server. A single
copy of the information, encrypted with the first key of the
server, is stored in a location accessible to all network
users. The second key is a private key of an authorized
user and is used by the server to encrypt the first key.
The encrypted first key is then stored by the server at a
storage location accessible by the authorized user. The
user accesses the storage location, obtains the encrypted
first key, and uses his private second key to decrypt and
thereby recover the first key. The user then decrypts the
stored information using the recovered first key.

Abstract: Compensation for pixel aberrations in a laser printer is
accomplished by selecting pixels (43) to be augmented, and providing additional
optical energy to the selected pixels. In one embodiment, the pixels are selected
by selecting pixels in combinations in which required pixel augmentation is
indicated. The additional optical energy may be applied at the sub-pixel level so
that a threshold of energy depletion on an optical photoreceptor (OPR) is not
reached where image development would occur. The energy applied at the sub-pixel
level results in enhancement of the selected pixels at an adjacent pixel
location.

IPC: B41J2/52

Abstract: A software/firmware based method for determining gray level values
to be assigned to a binary pixel image initially creates a linked list of templates,
each template associated with a gray level value to be assigned to an image pixel
value. Each template may include a central pixel value and plural neighbor pixel
values or just plural neighbor values. However, each template is a listing of entries
of template pixel values that are generally arranged in increasing concentric circles
about the central pixel value. Each template entry includes a field for a template
pixel value, a field for a template pixel address and a link field for a next template
entry, in the event of a non-match determination between the associated template
pixel value and an image pixel value. The method selects an image pixel window
from the binary image and compares a central image pixel in the window with a
logically, correspondingly located template pixel value. If a match is found, a next
image pixel is compared against a next template entry to determine if a match
occurs. This procedure continues, assuming matches are found, until all entries in
the template have been tested and found to match, in which case, the central
pixel of the image pixel window is changed in accordance with the gray level
value associated with the matching template. If, at any time, a non-match
occurs, the procedure moves to a linked template entry and the comparison
procedure continues in another template. The invention enables a binary search
to be executed which identifies a matching template (if any) after considering, on
the average, between 5 to 10 entries.
