Abstract: A rigid conformable structure (4, 5, 7, 8) that may be used individually or provided in an absorbent article (10) to minimize the ocurrence of fluid leakages in view of pres-sures caused by the movement of the body of the user. This rigid conformable structure has the property of dynamically adapting itself to the user's body so as to prevent the exist-ence of voids between either the user's body and the sheet (1, 3) of the absorbent article (10), or the user's underwear, should in be used directly in contact therewith, which pro-motes the ocurrence of the said leakages. This property is conferred by the provision of a plurality of individuals ele-ments that may move with rspect to each other while at the same time constituting a rigid structure. Finally, a process fox manufacturing disposable absorbent articles that incorpo-rate the structures of the invention is described.

Inventor: DOLPHIN DAVID
IPC: A61K47/48
Filed: 1990-06-07
Abstract: 2056431 9015059 PCTABS00002 A group of hydro-dibenzoporphyrins for example (I) prepared by di-Diels-Alder additions at the A and C or B and D rings of the appropriate divinyl porphyrins have absorption maxima in the range of 700-820 nanometers and are photosensitizing agents. These compounds are useful in treating disorders or conditions which are subject to hematoporphyrin derivative (HPD) treatment in the presence of light, or in treating biological materials generally to destroy unwanted targets such as viruses, cells and tissues. The use of the compounds of the invention permits irradiation with wavelengths other than those absorbed by blood. The compounds of the invention may also be conjugated to ligands specific for receptors or to specific immunoglobulins or fragments thereof to home to target tissues or cells for the radiation treatment. Use of these materials permits lower levels of photosensitizer to be used, thus preventing side reactions which might destroy normal tissues.

Title: Process for the detection of a nucleotidic sequence by use of the sandwich hybridation technique
Inventor: CROS PHILIPPE
IPC: C12Q1/6834
Filed: 1991-06-11
Abstract: A method for detecting a single-stranded nucleotide sequence in a sample which is known or thought to contain it, using sandwich hybridization comprising the step of incubating the sample with a capture probe which is passively fixed to a solid support and with a detector probe which is labelled with a non-radioactive marker. The capture and detector probes can hybridize with two non-overlapping regions respectively of the target nucleotide sequence being sought. The incubation step is followed by a washing step for removing reagents which have not been fixed by hybridization. The method is characterized in that the capture probe contains 9-30 nucleotides and is fixed to said solid support which is made of a material based on a hydrophobic compound. The method can be used particularly for diagnosing infectious or genetic diseases and for cell typing.

Title: Apparatus for Uniformly Distributing Gas and/or Liquid in an Underdrain Lateral System
Inventor: MAXSON RICHARD C
IPC: B01D24/22
Filed: 1992-08-07
Abstract: Underdrain lateral system, which is especially adapted for use in a gravity filter bed, includes, as its preferred embodiment, scallop-shaped laterals (26, 126) having an upper, wrapped wire, slotted screen surface (28). The screen surface supports and retains the filter media particles (118) directly, without the necessity of an underlying gravel layer, and is itself supported by channel-shaped rod members (34) which are welded to the wires (30). The web portions (36) of the channel-shaped rod members perform the function of simultaneously distributing air and water during backwashing, and include a smaller total area of apertures (38) in upper channels and a larger total area of apertures (40) in lower channels to cause a plenum (56) to be formed inside the laterals which ensures that the distribution of air and water will be uniform throughout the lateral, even if the lateral is not perfectly level. Distribution of the air and water throughout all of the laterals is made even more uniform by mounting the laterals on a header (124) and providing perforated flow tubes (122) which extend from each lateral into the header to produce an additional air plenum (135) therein. <IMAGE>   <IMAGE>

Title: Thread seal
Inventor: ORGAN ALAN H
IPC: F16J15/54
Filed: 1992-01-23
Abstract: A thread seal comprises a helical rib (6) for use with a threaded member (1). The end portions (7) of the rib (6) are axially staggered and are joined by a transverse thread bridging member (8) which engages a crest (9) of the thread between sucessive turns of the groove (2). The rib (6) has a tapering cross-section to project radially into the groove (2) and to form a lip seal over a limited axial width of the groove (2) throughout the greater part of the circumferential length of the rib (6). The end portions (7) together with the bridging member (8) are shaped to form a seal over the full axial width of the thread profile. By limiting the area of contact between the rib (6) and groove (2) over the greater part of the circumferential length of the rib (6) the frictional force between them is reduced.

Patent CA-2090611-A1 (CA)
Title: Printer with read-after-write print quality checking
Inventor: GILMORE MARK J
IPC: G06K5/02
Filed: 1992-07-29
Abstract: PRINTER WITH READ-AFTER-WRITE/PRINT QUALITY CHECKING        Abstract of the Disclosure A printer for forms such as lottery entry tickets has a print forming device which places both alphanumeric characters and machine scannable characters on a form, responsive to input data. The print forming device or the form is moved during printing, so as to form successive characters.   A scanner for reading the machine scannable characters previously printed by the print forming device is mounted such that the scanner views characters formed by the printer.  The output data of the scanner is compared to data stored in memory representing the previously printed scannable characters.  An error in the scanned code as compared to the stored data is interpreted as a printer failure, and the form is rejected.  The device is useful for assessing quality of the previously printed scannable characters as well as the alphanumeric characters because the characters are printed with the same print elements and defective operation of a print element causes gaps in both forms of characters.  The scannable characters can represent bar coded representations of the alphanumeric characters.

Patent CA-2099911-A1 (CA)
Title: Method and system for transactioning of modifications to a tree structured file
Inventor: ATKINSON ROBERT G
IPC: G06F17/30
Filed: 1993-07-06
Abstract: A method and system facilitate transactioning of modifica-tions to data. A hierarchical structure organizes data as nodes that contain the data. Each node is designated as transacted or direct. In response to receiving a request to modify data in a transacted node, the modification is associated with the transacted node. In response to receiving a request to commit the modification to file, the modification is dissociated from the transacted node. When the transacted node has an ancestor node that is transacted, the modification is associated with an ancestor node that is transacted. When the transacted node has no transacted ancestor node, the modification is stored directly in the file.      Before receiving the request to commit, a request to revert can cause disassociation of the modification from the transacted node. Depending on storage mode, a modification can be stored in a new or in an old portion of the file.
