Title: Lldpe blends with an ethylene-norbornene copolymer for resins of improved toughness and processibility for film production
Inventor: YANG HENRY WU-HSIANG
IPC: C08L23/08
Filed: 1998-03-13
Abstract: This invention is for LLDPE blends with an ethylene-norbornene copolymer for resins of improved toughness and processibility for film production. This invention provides LLDPE based resins which are significantly improved with respect to their capability to be fabricated into a film layer, particularly by a blown bubble extrusion technique. Films prepared of the LLDPE/E-NB melt blended resins of this invention are significantly improved with respect to certain of their film properties, such as tear strength, without detracting from the beneficial properties that a LLDPE otherwise provides to a film.

Title: Push-back storage rack
Inventor: LEWIS LYMAN F
IPC: A47F5/08
Filed: 1997-12-12
Abstract: A push-back storage rack comprises a frame (12) defining at least one storage bay (18) having a depth sufficient to accommodate a plurality of separate storage units (19); and a track-mounted carriage assembly mounted in the bay. The carriage assembly comprises at least two articulated carts (32) connected together end-to-end for pivotal movement about a transverse horizontal axis. The carts ride on a track (24) that has an upper track section (26), a lower track section (28), and an arcuate front section (30) that joins the upper and lower track sections. The track guides the carts for movement between the front and the rear of the bay on the upper track section and directs the carts downwardly and then rearwardly on the lower track section in an inverted position as the carts move forwardly at the front end of the upper track section. The carts are thus stored underneath the upper track section and are brought upwardly to the upper track section as the carts are filled and moved rearwardly in the upper track section.

Abstract: Optical supervisory channels are provided in an optical fiber network by receiving, in a first network element (10), a first optical supervisory channel signal (12) at a first wavelength (.lambda.1) from a first direction (14) on a first optical fiber (16), and by transmitting, from the first network element (10), a second optical supervisory channel signal (18) at a second wavelength (.lambda.2) in a second direction (20) and also on the first optical fiber (16). An amplified optical wavelength division multiplexed transmission system utilizing these supervisory signals divides a revenue-traffic amplifying region of an optical amplifier, with a lower portion being used for transmission in the first direction and an upper portion being used for transmission in the second direction. Both the first and second wavelengths are located outside of a flat-gain amplifying region of the optical amplifier.

Title: Oxazolidine-based hardeners for curing resorcinol resins in the bonding of wood articles
Inventor: WU GAOMING
IPC: C08G14/02
Filed: 1998-03-25
Abstract: An improved oxazolidine-based hardener to be used with a resorcinol resin or a tannin resin as the adhesive for the bonding of wood articles. Preferably, an oxazolidine is combined with a base such as NaOH  and a powdered absorbent such as wheat flour. The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength requirements after the glue is cured at room temperature for under 24 hours. The improved hardener composition is storage stable; it can be prepared anytime before its use, thus eliminating the need to prepare a hardener immediately prior to the glue use. Since it is formaldehyde-free, it eliminates the safety issues associated with handling formaldehyde or paraformaldehyde. Also, the hardener provides flexible gel time or working time. Since the resins can be cured at room temperature, heating in an oven is not needed but could be used to reduce curing time. If radio frequencies are used to cure the resins, the exposure time can be reduced.

Title: Biometric certificates
Inventor: DULUDE ROBERT S
IPC: G06F21/34
Filed: 1998-05-08
Abstract: Biometric identification is combined with digital certificates for electronic authentication as biometric certificates. The biometric certificates are managed through the use of a biometric certificate management system. Biometric certificates may be used in any electronic transaction requiring authentication of the participants. Biometric data is pre-stored in a biometric database of the biometric certificate management system by receiving data corresponding to physical characteristics of registered users through a biometric input device.  Subsequent transactions to be conducted over a network have digital signatures generated from the physical characteristics of a current user and from the electronic transaction. The electronic transactions is authenticated by comparison of hash values in the digital signature with re-created hash values. The user is authenticated by comparison against the pre-stored biometric certificates of the physical characteristics of users in the biometric database.

Abstract: F-CONNECTOR WITH DEFORMABLE BODY AND COMPRESSION RING      A compression type coaxial cable F-connector (20) includes a conventional coupling nut (38) and tubular post (32). A cylindrical body member (46) is secured to the tubular post and includes a sleeve (52) for receiving the jacket (30) of the coaxial cable (22). A circular relief (62) in the sleeve allows the end of such sleeve to be deformed inwardly toward the cable jacket. A compression ring (64) is mounted over the outer wall (54) of the sleeve of the cylindrical body member and includes a tapered inner bore (74) which forces the end of the sleeve inwardly against the cable jacket as the compression ring is advanced axially over the cylindrical body member. As the end of the sleeve is deformed inwardly, it extends just behind a circular barb (76) formed about the tubular post to pinch the cable jacket therebetween. The compression ring can be manufactured as a separate component, or the compression ring can initially be integral with the sleeve of the cylindrical body member and attached thereto by a frangible connection (102).

Title: Rapid electrochemical assay for antibiotic and cytotoxic drug susceptibility in microorganisms
Inventor: ERTL PETER
IPC: C12Q1/18
Filed: 2000-03-02
Abstract: This invention presents rapid methods for evaluating the effects of antimicrobial compounds on microorganisms based upon the microorganism's ability to transport electrons to an external chemical oxidant (a mediator) that is added to the microorganism sample. The mediator interacts with the terminal components of the respiratory pathway and the extent of its consumption is related to the ability of the microorganism to respire. However, under the assay conditions described herein the extent of mediator consumption is different from the microorganisms ability to consume oxygen, due to the addition of metabolizable compounds to the assay mixtures.  The consumed mediator is subsequently measured electrochemically (amperometrically or coulometrically) at the working electrode of a standard two-electrode or three-electrode electrochemical cell. The electrochemical signals (change of current or charge with time) obtained with microorganism suspensions incubated in the absence and presence of antimicrobial compounds are significantly different. These signal differences can be used to screen for antimicrobial effectiveness of antibiotic drugs against clinically important multi-drug-resistant organisms, to screen for the presence of unlawful levels of antibiotic compounds in foodstuffs, or to screen potential new antimicrobial compounds for effectiveness against different species of microorganisms.

Title: A method and system for providing interactive sms messaging
Inventor: ARMSTRONG CHRISTOPHER
IPC: H04W4/14
Filed: 2000-07-14
Abstract: The invention provides an interactive short messaging service (SMS) in which the short messaging service provider (SMP) stores short messages as content short messages (CSMs) which CSMs are then stored in a short messages menu (SMM).  A user dials up the desired SMM, the SMP downloads the SMM and immediately terminates the call. The user now has a menu which may lead directly to CSMs which can be contacted directly or which can be a list of further SMMs. For example, the first SMM downloaded could be airline arrivals from one airport and on being downloaded could list all airlines servicing that airport each with a unique contact number i.e. a further SMM. The user clicks onto the desired airline from this SMM. A second CSM is downloaded in this case the times of arrivals of all that airline's flights that day. This may be sufficient for the user. The time taken for the two calls is minimal. The advantage is that it overcomes the problems inherent in present SMSs.
