Title: Processes for preparing sildenafil
Inventor: TAO YONG
IPC: C07D231/40
Filed: 1998-05-22
Abstract: Sildenafil, a known pharmaceutical chemical useful in treatment of male sexual dysfunction, is prepared by processes in which the final chemical intermiadiate is of significantly lower basicity than sildenafil itself, so that sildenafil can be extracted in substantially pure form from the organic reaction mixture in which it is made by adding an aqueous medium of appropriately chosen acidic pH and causing phase shift of the sildenafil to occur selectively into the aqueous phase.

Abstract: A kick-boxing exercise device includes a weighted base unit which supports a target section. The target section having an appearance of a head, neck and torso of a human. The target section is vertically adjustable on the base unit and includes a plurality of target areas. A plurality of LEDs are mounted within the target areas which illuminate as the specific target areas are to be punched or kicked by a user. A foam pad is attached to the target section for cushioning the punch or kick of the user. An electronic control unit illuminates the LEDs in a preprogrammed punch or kick sequence. Various skill levels are provided to sequentially illuminate the LEDs at various speeds. The electronic control unit includes a scoring system which allows the user to evaluate his or her performance. A sensor detects contact with the target section and triggers illumination of the next LED in the sequence. A sensor adjustment dial allows the sensitivity of the sensor to be adjusted by the user.

IPC: G06F9/44

Abstract: In most object-oriented languages, the relationships are buried deep in the implementations of the classes. That is, relationships, even if described, along with objects in a model, become implicit in the implementation of the model. Typically the objects are referenced directly from instance variables. Each object participating in a relationship must maintain referential consistency. By representing the relationships between two objects as variables in both, the semantics of the relationship is lost because it is distributed among the classes. The present invention creates a explicit relationship model, in addition to a domain object model, to use as the basis for writing browser applications. This is done by writing the relationships between elements as types when writing the class for the object(s). The types can be further defined in terms of constraints for interacting with specific other element types. The resulting relationship model can then used to devise appropriate actions in the context of a user interface. A smart browser uses the relationship information to automatically build a menu with available actions for any relationship. Changes to objects in the model can be communicated efficiently to all views in terms of relationships. Any browser that does not deal with the relationship type specified in the change simply ignores it, without interrogating the elements in its view.

Inventor: TAKAGI NOBUAKI
IPC: B22D41/40
Filed: 1998-12-17
Abstract: A sliding gate nozzle device is disclosed which, even when the position of a retreat or advance limit of a sliding metal frame changes, can effect the application of a surface pressure and ensure a gap for the entry of surface pressure blocks therein and which can relieve the applied surface pressure easily. The sliding gate nozzle device comprises a fixed metal frame 1, an opening/closing metal frame 2 movable with respect to the fixed metal frame 1, a sliding metal frame 3 disposed between the fixed metal frame 1 and the opening/closing metal frame 2 and slidable up to a limit position, and a surface pressure applying mechanism which presses the opening/closing metal frame 2 against the fixed metal frame 1 when the opening/closing metal frame moved to a surface pressure applying position W. In the sliding gate nozzle device, the opening/closing metal frame 2 is co-moveded with the sliding metal frame 3 and a surface pressure applying member 12 which prevents the sliding metal frame 3 from reaching the above limit position when the opening/closing metal frame 2 has reached the surface pressure applying position W is disposed removably between the opening/closing metal frame and the sliding metal frame. The "limit position" means an advance or retreat limit in a movable stroke range of the sliding metal frame.

Title: Method and device in connection with impingement drying and/or through-drying of a paper web or of an equivalent web-like material
Inventor: SUNDQVIST HANS
IPC: D21F5/00
Filed: 1997-06-17
Abstract: The invention concerns a method and a device in connection with impingement drying and/or through-drying of a paper web or equivalent. In the invention the paper web (W) is dried by blowing hot air or equivalent by means of an impingement drying device (10) perpendicularly to the web (W), which is passed on support of a wire (F) past the impingement drying device (10). The web (W) and the wire (F) are supported by the intermediate of blowings produced by means of vacuum blow boxes (30) across the entire width of the web. The first blowings are blown at a speed substantially higher than the speed of the drying wire (F) and the outlet direction of the blowings is substantially the same as the running direction of the drying wire (F). By means of said first blowings steam or air is ejected out of the space between the wire (F) and the wall placed in connection with the blow boxes (30). The second jets produced by means of the blow boxes are blown in the direction opposite to the running direction of the wire (F) so as to seal the area of vacuum between the wire (F) and the blow box (30). The same medium is used as the blow medium in the blow box (30) as is used in the impingement drying unit (10).

Title: Diagnosis of williams syndrome and williams syndrome cognitive profile by analysis of a lim-kinase gene
Inventor: MORRIS COLLEEN A
IPC: C12Q1/68
Filed: 1997-07-07
Abstract: Williams syndrome (WS) is a developmental disorder that includes poor visuospadal constructive cognition. This syndrome has been studied to idendify genes important for human cognitive development. Two families are described which have a partial WS phenotype;  affected members have the specific WS cognitive profile and vascular disease, but lack other WS features. Submicroscopic chromosome 7q11.23 deletions cosegregate with this phenotype in both families. DNA  sequence analyses of the region affected by the smallest (63.6 kb) deletion revealed two genes, elastin (ELN) and LIM-kinase 1(LIMK1). The latter encodes a novel protein kinase with LIM domains and is strongly expressed in the brain. Because ELN mutations cause vascular disease but not cognitive abnornalities, these data implicate LIMK1 hemizygosity in impaired visuospatial constructive cognition.

Patent CA-2263406-A1 (CA)
Inventor: SIDES JAMES R
IPC: B60R21/26
Filed: 1996-08-29
Abstract: Particulate-free non-toxic gases are generated in a hybrid generator device by conducting the ignition of the propellant with an effective oxidizer, using a mixture of a molecular oxygen-containing gas and argon by varying the ratio of the gas to argon to provide only non-toxic reaction products in the exhaust gas. The inventive device includes an initiator (1), which ignites in response to a sensor and gives off hot gas that ignites the ignition charge (2) which causes the main generant charge (8) to combust, generating the inflation gas mixture (3). When the pressure in the gas mixture increases to a certain point, the seal disc (6) ruptures permitting the gas mixture to exit the manifold (4) through the outlet ports (5) and inflate an air bag. The generant container (9) holds the main generant charge (8). All the charges and the inflation gas mixture are enclosed in the pressure tank (7).

Title: Method for resource allocation and routing in multi-service virtual private networks
Inventor: MITRA DEBASIS
IPC: H04Q11/04
Filed: 1999-03-18
Abstract: We describe a method for solving the joint problem of optimal routing and optimal bandwidth allocation in a network that supports plural subnetworks and plural communication services. Our method involves, for each source-destination pair communicating via a given subnetwork and a given class of service, determining a traffic rate to be offered to each of a set of permissible routes between that source and that destination, in the given subnetwork and service class. Our method further involves allocating a respective bandwidth to each link of each subnetwork.  Significantly, the determinations of traffic rate to be offered, and the allocations of bandwidth to respective links of subnetworks, are performed in a mutually responsive manner.
