Title: Message display unit with symbols made from fluorescent pins - is illuminated by integral UV lamp and reflector
IPC: G09F7/06
Filed: 1987-12-08
Abstract: The display system has a simple U-shaped channel extrusion (1), with a high back wall (2) and a low front wall (6). The back wall is pierced by a regular matrix of identical sized holes (5). The message to be displayed is built up as characters or symbols by inserting lines of mushroom-headed pins (3) into selected holes in the matrix. The novel feature of ther present display is that the heads of the pins are coated with a fluorescent material, which can be activated by a low power ultra-violet lamp (8) mounted with a reflector (9) in the flat base of the extrusion. The UV light is invisible to the eye and therefore only the heads of the pins will be visible in low ambient lighting conditions.

Title: System for raising and lowering a liner of a fluidbearing receptable
Inventor: MCROBERT IAN
IPC: E04H4/14
Filed: 1999-06-28
Abstract: A system (10) for raising and lowering a liner (12) or a swimming pool (14) includes a plate (22) used to define a spill way (24) for providing fluid communication between an outside surface (26) of the liner (12) and an inside surface (16) of the pool (14). The liner (12) is detached from surface (16) of the pool in the region behind the plate (22) and reattached along upper edge (28) of the plate (22) using a conventional locking strip (20). Conduit (30) has a length (30') which extends along back face (32) of plate (22) below the upper edge (28). Holes (34) cut in the plate (22) provide communication with length (30'). Conduit (36) having a length (36') extends across the back face (32) near its lower edge (38) to provide air to the spill way (24). The length (36') is provided with a number of holes (40) for admitting air into the spill way (24). In order to lift the liner (12), air is directed through conduits (30, 30') to the outside surface (26) of liner (12). The air progressively lifts the liner up and away from the inside surface (16) displacing water held within the pool (14) to flow over upper edge (28) into the spill way (24) so that the water now lies beneath the outside surface (26). In this way the liner (12) is progressively raised to eventually lie above the level of the water. To return liner (12) to its lining position air is passed through conduits (30, 36) into spill way (24). As the air rises it carries water up the spill way (24) and over the upper edge (28) onto the inside surface of liner (12) to sink the liner (12) back to its lining position.

Title: Method and device for collecting and testing for fecal accult blood
Inventor: BAKER JOSEFINA TECSON
IPC: G01N33/72
Filed: 1987-03-09
Abstract: A method and device for collecting and testing fecal occult blood which permits multiple analyses of a single fecal sample. The device is a combination of a sampler for collecting the fecal matter and a test slide. The fecal sampler comprises a pocket-like wipe pad for obtaining direct anal stool smears. An insert is disposed in the pocket of the wipe pad. The slide has a profiled opening similar to the design of the wipe pad. This opening acts as a receptacle for the pad when the fecal smear is transferred to the guaiac specimen receiving sheet of the slide. When the slide is closed the insert can be removed from the wipe pad. This design permits an analysis to be done on the specimen receiving sheet of the slide together with a second confirmatory test for human hemoglobin on portions of the insert. The fecal material on the insert is physically removed from the guaiac specimen receiving sheet.
Patent PT-89683-A (PT)
Inventor: KANEKO TAKUSHI
IPC: A61K47/48
Filed: 1989-02-10
Abstract: The present invention relates to novel immunoconjugates, methods for their production, pharmaceutical compositions and method for delivering cytotoxic anthracyclines to a selected population of cells desired to be eliminated. More particularly, the invention relates to immunoconjugates comprised of an antibody reactive with a selected cell population, having a number of anthracycline molecules linked to its structure. Each anthracycline molecule, having a keto group at the C-13 position, is conjugated to the antibody via a linker arm and is bound to that linker arm via an acid-sensitive acylhydrazone bond at the 13-keto position of the anthracycline. The immunoconjugates and methods of the invention are useful in antibody-mediated drug delivery systems for the preferential killing of a selected cell population in the treatment of diseases such as cancers and other tumors, non-cytocidal viral or other pathogenic infections, and autoimmune disorders.
