Title: System for eliminating unauthorized electronic mail
Inventor: KATSIKAS PETER L
IPC: G06Q10/00
Filed: 2000-08-25
Abstract: A system for eliminating unauthorized email sent to a user on a network employs an email-receiving server (104) connected between the network and the user's email client (101) for receiving email addressed to the user and rejecting those in which the sender address does not match any of sender addresses maintained on an "authorized senders" list (ASL list). The ASL lists are maintained by an ASL manager (211) in an ASL database (203a) operable with a spam processor module (203). A redirector module (202) rejects the email if, upon sending a request for validation to the spam processor module, the sender's address does not match any authorized sender address on the ASL list.  Email rejected by the redirector module is redirected to a web-based messaging (WBM) module (204, 205) which sends a message to the sender to confirm that the sender is a legitimate sender of email to the intended recipient. If the sender logs on to confirm their status, the WBM module executes an interaction procedure which can only be performed by a human, in order to ensure that the confirmation procedure is not performed by a mechanical program. The ASL  manager maintains the ASL lists based upon sender address data collected from various sources an analyses of various email usage factors, including sent email, received email, contact lists maintained by the user, user preference inputs, third party programs, etc.

Filed: 2001-02-15
Abstract: The present disclosed system is directed toward a communication and management system that dynamically targets network devices for content deployment, such as application programs, device drivers, configuration files, and registry subhives. Moreover, the present system targets users of network devices for promotions, such as advertisements offered by Internet e-commerce sites.  Promotions are generally icons or graphic images with links to host web servers overlaying a video display, but also includes audio and video clips or data streams. Network devices and their users are targeted through user profiles. User profiles are created when network devices register with the system server and are continually updated with information provided by user activity and event logs that are periodically uploaded from each device. A  scalable messaging system provides for data transmission between the system server and among the network devices such that it is neutral as to the specific hardware platforms on which it is implemented.

Title: A process for hydrolyzing starch without ph adjustment
Inventor: SINGLEY ERIC C
IPC: C12N9/28
Filed: 2003-01-03
Abstract: An alpha-amylase enzyme obtained from Bacillus acidocaldarius species is utilized to liquefy starch at a pH as low as 3.0 without the need to add thermostabilizing agents such as calcium. The alpha-amylase produces acceptable DE yields in a single liquefaction step and does not need to be inactivated prior to conducting saccharification which can proceed without adjustment of the pH of the liquefact. Alternatively, a secondary liquefaction process can be utilized, in which case two additions of the alpha-amylase are used resulting in a combined low dosage of the enzyme.

Abstract: In a shared transmission media communication system with an upstream frequen cy and a downstream frequency carrying telephony such as TDM PCM data in additi on to other data types, it is useful to use a master frame format 604 that send s downstream the TDM PCM data sub-packets 400 to a set of downstream modem devices (60, 62, 64, 66, 68, 70) and to provide the downstream modem devices  with staggered times to respond 320. The master frame then continues to send  downstream data types such as video that do not trigger a response from the downstream modems during a period of time 636 allocated for the downstream modems to send upstream transmissions of TDM PCM. A set of rules can be implemented within this system to favor the transmission of higher priority data types while preventing any data type from taking too much of the downstream bandwidth.

Abstract: A system and method for transporting high-viscosity, high-solids, dewatered materials essentially includes a progressing cavity pump system utilizing a twin-screw feeder with an extended tunnel section. The feeding of the materi al into an extended tunnel section of the twin screw feeder creates a positive pressure, which assists in feeding the product into the suction housing of t he progressing cavity pump, and correspondingly, into the pumping elements. Thi s increases volumetric (fill) efficiency of the progressing cavity pump, there by allowing a smaller pump to be used. The suction housing of the progressing cavity pump includes an auger positioned therein that is directly coupled to , and preferably integral with, the progressing cavity rotor. The universal joint is moved from the position in front of the stator entrance to a point behind the auger and suction inlet opening to improve flow of material from the suction housing to the progressing cavity pump elements. The inlet condu it coupled to the transition housing is angled slightly towards the direction o f flow to further improve the flow efficiency and increase the fill rate of th e progressing cavity pump elements.

Title: Synthesis of complex carbohydrates
Inventor: ZOU WEI
IPC: A61P35/00
Filed: 2001-08-22
Abstract: A tailor-assembly approach is employed for synthesis of complex carbohydrates wherein a polysaccharide is degraded and the shorter product obtained from the degradation is subjected to enzymatic modification to add a sugar moiety. The products may be useful in the preparation of a cancer vaccine. In one example, oligosaccharides of the type Ia group B Streptococcus (GBSIa) capsular polysaccharide and multivalent sialyl Lex antigens are specifically described.  GBSIa polysaccharide was depolymerized by partial Smith degradation to fragments representing asialo core repeating units. Enzymatic sialylation of these oligomers furnished GBSIa repeating units (from monomer to pentamer).  Fucosylation on GlcNAc residues of GBSIa oligomers afforded oligosaccharides that carry multiple sialyl Lex epitopes.
