Title: Intercalates formed by co-intercalation of monomer, oligomer or polymer intercalants and surface modifier intercalants and layered materials and nanocomposites prepared with the intercalates
Inventor: TSIPURSKY SEMEON
IPC: C08L101/00
Filed: 1997-10-14
Abstract: The present invention discloses intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer surface modifier including an alkyl radical having at least 6 carbon atoms and a polymerizable monomer, oligomer or polymer.  The intercalant monomer surface modifier converts the interlayer region of the layered materials from hydrophilic to hydrophobic, therefore, polymerizable monomers, oligomers or polymers can be easily intercalated into the interlayer spacing.  The co-presence of the intercalant monomer surface modifier and polymerizable monomer, oligomer or polymer provide an environment for more polymerizable monomers, oligomers or polymers to be intercalated into the interlayer spacing and the intercalates are readily exfoliated into polymer matrices to form nanocomposites.  The nanocomposites (e.g., epoxyclay) prepared from the intercalates demonstrated enhanced mechanical, thermal and chemical resistance compared with pristine polymer matrices.

Title: Method and apparatus for delivering a cased glass stream
Inventor: SCOTT GARRETT L
IPC: C03B17/02
Filed: 1998-03-27
Abstract: Apparatus for forming a cased glass stream that includes at least one pair of aligned orifices coupled to sources of core and casing glass such that glass flows by gravity from the glass sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing mounted on a frame for movement into seating engagement of the orifice housing against the core and casing glass delivery mechanisms. A fluid manifold is mounted on the orifice housing, with an inlet for connection to a source of cooling fluid such as air. A plurality of outlets on the manifold are directed toward the area of seating engagement between the orifice ring housing and the core and casing glass delivery mechanisms for cooling the seating area and thereby reducing leakage of glass between the housing and the glass delivery mechanisms. Inasmuch as the cooling air manifold is mounted on and carried by the orifice housing, the manifold outlets are automatically directed toward the seating area upon seating of the orifice housing against the glass delivery mechanisms, and do not require separate replacement or adjustment.

Title: Using web page hit statistics to anticipate call center traffic
Inventor: BAUER DAVID L
IPC: H04M3/523
Filed: 1998-07-31
Abstract: In a call center (106) associated with a World-Wide Web site whose pages (121, 122) provide a call-request capability (115), the call center receives notifications of page hits and call requests from the Web server (103) and uses these notifications to determine a historical page hits-to-call requests ratio. It then uses the ratio along with current page-hit notifications to predict a volume of calls that will soon need to be handled by the call center and staffing the call center in anticipation of the predicted call volume. The notifications are further used in conjunction with knowledge of information about the content of the Web pages to predict what agent skills will be needed to handle the calls, and to staff agent splits accordingly.

Title: Apparatus for authenticating products and authorizing processes using the magnetic properties of a marker
Inventor: ROSEMAN MORTON F
IPC: G07D7/04
Filed: 1999-01-14
Abstract: This invention provides a system that utilizes the magnetic properties of specific materials to provide an authentication and/or authorization function.  The system consists of two parts. The first is a marker that contains a magnetic material with special magnetic properties and is attached to the item that is to be authenticated or is to be part of a subsequent information transfer process requiring authorization. The second is a reader. The reader contains a transmitter that generates the electromagnetic search field and energizes the magnetic material and a receiver that analyzes the signal produced by the resulting interaction with the magnetic material and gives a go/no go decision based upon a match with stored information. The reader employs a feedback control system to stabilize the measurement environment, thereby producing accurate, high quality results. The go/no go signal in itself can be used as the authentication signal and can also be used to energize an actuator for the purpose of automatically authorizing a process such as photocopying, sending a fax, data copying and data communication.

Title: Mechanical deaeration of bituminous froth
Inventor: SPENCE JONATHAN R
IPC: B01D19/00
Filed: 1999-03-02
Abstract: Aerated bitumen froth obtained from oil sands must be deaerated so that it can be pumped through a pipeline. Mechanical shearing is effective to deaerate bitumen froth to an air content of below 10 volume percent.   Mechanical deaeration of bitumen froth can be achieved either by passing the froth through a confining passageway and shearing the froth with an impeller while it is in the passageway or temporarily retaining the aerated froth in a tank and circulating it repeatedly through a pump.
