Title: Thermally reversible isocyanate polymers
Inventor: MARKLE RICHARD A
IPC: C08G73/10
Filed: 1991-02-04
Granted: 2002-07-09
Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen func-tionality. High-performance characteristics are incorporated into the polymer by using polyimide, aromatic polycarbonate, aro-matic polyester, polyphenylene sulfide, and poly(parabanic acid) oligomers.  Low-temperature flexibility and toughness are im-parted to the polymers by using prepolymers such as polycaprolactone diols, polytetramethylene ether glycols and polyaliphatic carbonate diols. Ionic bonding and liquid-crystal functionality may also be incorporated into the compositions. The compositions are useful as hot-melt adhesives, coatings, and moldings and in injection reaction molding applications and composite and lami-nate fabrication.

Title: Vented mold and use thereof
Inventor: CLARK LESLIE EDWARD
IPC: B29C44/34
Filed: 1992-09-02
Granted: 1996-09-03
Abstract: A novel method of molding an article includes providing a mould with a vent of a pre-determined size such that, due to the difference in viscosities, gases to be vented from the mold may easily pass through the vent while the material to be molded cannot quickly pass through the vent. In fact, the vent is designed such that the material to be molded which enters the vent, does not exit the end of the vent. In the most preferred embodiment, the vent is in the form of a thin ribbon-like groove so that the material to be molded which does enter the vent forms a thin ribbon of extruded material which need not be removed prior to a finish cover being applied to the molded article.

Title: Apparatus for providing dynamic selection of modem protocol to support multiple modem types
Inventor: WALSH JAMES P
IPC: H04M11/06
Filed: 1992-11-10
Granted: 1998-06-09
Abstract: A computer is programmed in accordance with an algorithm which allows it to send a series of tentative unique initialization commands to a port which should be connected to a modem for the purpose of establishing what type of modem is connected if any. In accordance with an internal flag setting, an appropriate translation table is then used in any future communications with that modem to convert the basic commands used by the computer operated device to commands that will be recognized by the modem in setting up communications with other modems at the other end of a transmission line and for terminating said communications. The algorithm involved is also able to ascertain whether or not an operable modem is connected to a port by monitoring the responses obtained. Thus, modems can be changed and potential technician error is eliminated due to the dynamic selection capabilities of the computer programmed to operate in accordance with the inventive concept algorithm.

Granted: 2002-10-08
Abstract: A dispensing device for dispensing a pre-measured amount of a liquid or a powdered material from a container. The dispensing device fits inside the container and is coupled to the mouth of the container. The device comprises a lower measuring reservoir, a discharge tube, and an upper compartment. The upper compartment couples the device to the mouth of the container and also includes a pressure equalizer. The measuring reservoir is suspended inside the container by the discharge tube and upper compartment so that material can move freely around the measuring reservoir. To dispense a pre-measured amount of material, the container is inverted. This causes the material to be captured by the measuring reservoir and travel to the mouth of the container through the discharge tube. To facilitate capturing material, the measuring reservoir includes a number of inlet notches. The measuring reservoir also includes an overflow tube. The function of the overflow tube is to meter the amount of material which is captured by the reservoir by releasing any excess material which may accumulate when the device is inverted. The dispensing device can also include a flap closure between the discharge tube and the measuring reservoir. The flap prevents the material from entering the discharge tube until the container is inverted. In another embodiment of the invention, the bottom of the container includes a collection area which is situated underneath the measuring reservoir. The bottom of the container can be sloped and have channels to facilitate moving the material to the collecting area thereby facilitating capturing the material when the level is low inside the container. The dispensing device according to the present invention can be easily manufactured by a plastic molding process and can be reused with various containers.

Title: Novel human cdc25 genes, encoded products and uses therefor
Inventor: BEACH DAVID H
IPC: C12Q1/68
Filed: 1992-11-17
Granted: 2003-07-01
Abstract: Two previously undescribed human cdc25 genes, designated cdc25 A and cdc25 B, which have been shown to have an en-dogenous tyrosine phosphatase activity that can be specifically activated by B-type cyclin, in the complete absence of cdc2 are de-scribed. As a result of this work, new approaches to regulating the cell cycle in eukaryotic cells and, particularly, to regulating the activity of tyrosine specific phosphatases which play a key role in the cell cycle are available. Applicant's invention relates to methods of regulating the cell cycle and, specifically, to regulating activation of cdc2-kinase, through alteration of the activity and/or levels of tyrosine phosphatases or through alteration of the interaction of components of MPF. The present invention also relates to agents or compositions useful in the method of regulating (inhibiting or enhancing) the cell cycle. Such agents or com-positions can be inhibitors (such as low molecular weight peptides or compounds, either organic or inorganic) of the catalytic ac-tivity of tyrosine specific PTPases (particularly cdc25), blocking agents which interfere with interaction or binding of the tyrosine specific PTPase with cyclin or the cyclin/cdc2 complex, or agents which interfere directly with the catalytic activity of the PTPases. The invention also pertains to an assay for identifying agents which alter stimulation of kinase activity of pre-MPF and thus alter activation of MPF and entry into mitosis. Such agents are also the subject of this invention.
