Filed: 2000-04-07
Abstract: The present invention relates to absorbent articles such as sanitary napkins , panty liners, diapers, adult incontinence pads and briefs, and the like havi ng an improved combination of skin feel and fluid handling properties, such as fluid acquisition and retention. This improved combination is provided by structures where the absorbent core has a high capillary pressure which help s the core to rapidly acquire bodily fluids deposited on the body surface of t he absorbent article and to retain such fluids after they have been acquired. Absorbent gelling materials with reduced gel blocking are a preferred core component that aids in fluid retention by providing an osmotic fluid retenti on mechanism. The topsheets of the present invention cooperate with the core by  being both fluid permeable and providing a barrier to rewet of acquired fluids. The topsheet also has a multiplicity of fibrils that create the body  surface of the absorbent article. These fibrils are disposed at a density an d have dimensions and mechanical properties such that the body surface has a soft, velutinous body feel.

Title: Positioning and conveying well apparatus and method
Inventor: OHMER HERVE
IPC: E21B47/09
Filed: 2000-10-16
Abstract: In a broad aspect, the invention may include a nipple (10), a deflector (42), and a conveying tool (116). The nipple may include an upper sealing surface (26) and a lower sealing surface (28). The nipple may also include a discriminator/muleshoe (30) having an alignment profile (32) and an alignment slot (34). A  protuberance/bump (40) may be disposed in the alignment slot. The deflector (42) may include an upper seal (52) and a lower seal (54) adapted for engagement with upper and lower sealing surfaces (26, 28), respectively, on the nipple. When the upper and lower seals are engaged with the upper and lower sealing surfaces, fluid circulation is substantially restricted thereby resulting in an increase in pressure that is detectable at the earth's surface. The pressure increase provides a signal that the deflector is properly positioned in the nipple. The conveying tool may include a flexible arm (122) having a latching finger (124) that is releasably engageable with a latching profile (51) in the deflector. The latching profile may be on an inclined, concave surface of a whipstock (44).  Related methods are also provided.

Title: Tire assembling method and refitting apparatus for use in refit of tire assembly
Inventor: KIMBARA TOSHIYUKI
IPC: B60C25/132
Filed: 2002-06-26
Abstract: A refitting apparatus for a tire assembly "w" having a disk wheel "a" having engaging rims and a tire "d" fitted to the disk wheel and having tire bead rims and side walls. The apparatus is constituted to perform a refit process in which a pressing step of bringing one of the tire bead rims "e" of the tire into pressing contact with one of the engaging rims "b" of the disk wheel "a" by supplying air into the tire "d" and a releasing step of releasing the one of tire bead rims "e" of the tire "d" from the one of engaging rims "b" of the disk wheel "a" are repeated a predetermined number of times for each of the tire bead rims "e". Since the tire bead rims "e" are repeatedly brought into pressing contact with the engaging rims "b" and released therefrom, the tire bead rims "e" snugly fit with the engaging rims "b", so that the RFV value is considerably lowered and stable maneuverability during driving can be obtained unless the fitting state is subsequently changed.
