Filed: 1996-11-28
Granted: 2002-04-30
Abstract: A resilient gasket is disclosed for providing a seal between corrugated pipes having a plurality of concentric ribs on their outer surface, such as drain and sewer pipes to be buried in soil. The gasket comprises a base which is received around a first pipe over top of a rib adjacent an end of the first pipe, with an inner surface adapted to mate with a radially outer surface of the rib, and with legs adapted to extend along forward and rearwardly-sloped faces of the rib.      The outer surface of the base is provided with sealing means to engage the inner surface of the bell adjacent the end of a second pipe. The gasket also has a flap extending outwardly and forwardly from the forwardly extending leg. The flap and the forward leg form a V-shaped member. The flap engages the inner surface of the bell when the first pipe is inserted into the second pipe, and the gasket is rotated rearwardly relative to the rib. When the flap engages the inner surface of the bell, it prevents further rearward displacement of the gasket relative to the rib, thus preventing displacement of the gasket from the rib. The gasket also helps prevent gasket blowout during periods of unusually heavy water flow through the pipes.

Granted: 2005-02-08
Abstract: A mount for securing a punching bag or other exercise equipment to a support structure has a helical spring nested around a rotatable, slidable rod. The resulting structure relieves torsional stresses and absorbs longitudinal forces experienced by the punching bag or other exercise equipment during its use, thus prolonging the life of such bag or equipment. The nested or non-serial connection of elements in the mount shortens the operative length of the mount, which is advantageous when the vertical mounting location for the bag or equipment is limited, such as by the presence of a standard ceiling.

Granted: 2010-02-23
Abstract: L'invention concerne un animal eucaryote non humain transgénique dont les cellules germinales et les cellules somatiques contiennent la séquence de la protéine précurseur amyloïde introduite dans l'animal, ou bien un ancêtre de cet animal, à un stade embryonnaire. Chez les souris se développe un trouble du système nerveux central lié à l'âge et caractérisé par une agitation, la néophobie, des attaques, une inactivité, une utilisation réduite du glucose cérébral, une gliose cortico-limbique, et la mort. Une accélération de ce trouble survient chez les souris transgéniques s'exprimant des protéines précurseurs amyloïdes d'Alzheimer (APP) humaines et de souris produites à l'aide d'un vecteur cosmide dérivé d'un gène protéique de prion de hamster conférant une expression qui est dépendante du nombre de copies mais indépendante de la position. Chez les souris transgéniques, ce trouble se développe en relation directe avec la concentration cérébrale d'APP transgénique, mais l'APP mutante confère le phénotype à des niveaux d'expression plus faibles que l'APP de type sauvage. Ce trouble survient en l'absence de dépôt de plaques amyloïdes extracellulaires, ce qui indique que certaines activités pathogènes de l'APP sont dissociées de la formation de plaques amyloïdes.
