Abstract: A waterproof shoe includes a hollow sole pad having an intermediate opening, an inner marginal end confining the opening, an outer marginal portion spaced from and extending around the inner marginal end, and an upstanding flange which projects from the sole pad between the outer marginal portion and the inner marginal end and which loops around the opening .      An upper has a bottom open end stitched to one of the outer marginal portion and the upstanding flange. A lining sleeve is disposed inside the upper and is made of a material which is impervious to water but is pervious to vapors. The lining sleeve has a bottom open end stitched to the upstanding flange of the sole pad to form a stitch seam which is then sealed by means of waterproof means. The bottomless lining sleeve and the hollow sole pad permits the lining sleeve to be secured and sealed watertight to the sole pad in a less complicated manner. Drainage is permitted at the stitch seam of the sole pad and the upper.

Title: Disposable cup with spill resistant lid
Inventor: HOWES-JONES DARYL J
IPC: B65D3/20
Filed: 2000-06-07
Granted: 2002-01-08
Abstract: A disposable cup has a bottom insert, and a substantially truncated conical body having an integral lid and a cup opening. The lid is movable between a raised position and a closed position, possibly via a semi-closed position. The lid has a free edge, with a liquid passage opening allowing liquid passage when the lid is in said closed position. The lid is foldably joined to the body along an arcuate first score line. The lid further has second score lines arranged at respective ends of the free edge, the second score lines connecting the free edge and the first score line so that, when the lid is pushed towards the cup opening, the lid flips into a position inside the cup opening, the movement of the lid being substantially aided by the folding of the lid along the second score lines. The lid has a larger cross-dimension than the cross-dimension of the body at the closed position of the lid, so that, when the lid portion is pushed further into the body, the lid is bent into a convex shape to seal liquid access along the inside of the cup, and the lid is partly held in the cup in the closed position by frictional forces between the lid and the inside of the cup, and partly by the second score lines causing outer portions of the lid to bend to a substantially vertical position, thereby increasing the force holding the lid in the closed position.

Abstract: Techniques for physically implementing fiber ring networks which achieve full mesh connectivity, such networks including a 2-fiber WDM ring network composed of a clockwise ring, and a 4-fiber WDM Self-Healing Ring Network. The number of wavelengths required is derived for both odd and even number of nodes (901-904) on the ring. To physically set-up all required connections in the network, optimal wavelength assignment algorithms are devised so that the wavelength assignment between nodes (901-904) on the ring is systematic and engenders full mesh connectivity while avoiding any possible violation of the color clash constraint. An illustrative algorithm uses a simple matrix approach for calculating the interconnection arrangement.

Title: Exercise device
Inventor: ARNOLD PETER
IPC: A63B23/035
Filed: 2000-12-04
Granted: 2009-06-30
Abstract: The exercise device (10) exercises both the upper and lower body in associated motion, while preventing derailment or other related instability of the lower body linkage, due to the connection and force imparted from the upper body linkage. The device includes a frame (12) which has a forward upright member (20).  The axle mounts (30) and (32) are attached to the rear region of the frame (12) and support a transverse axle (34) which is preferably operatively connected to a flywheel (36). The ends of the transverse axle (34) rotatably engage left and right crank arm assemblies (40) and (50) that are coupled to the left and right foot links (60) and (70) so that the foot links travel in an arcuate reciprocal path as the transverse axle rotates. The forward ends (62) and (72) of the foot links terminate in rollers (68) and (78), which engage guide tracks (42) and (52) that are mounted to the frame. The forward ends (62) and (72) of the foot links are operatively connected to safety engagement assemblies (100) and (110), which in turn are operatively connected to coupling regions (86) and (96) of swing arm mechanisms. The swing arm mechanisms are rotatably connected to the forward upright member (20) at pivot points (84) and (94). The swing arm mechanisms further contain hand-gripping portions (82) and (92), and the foot links further contain foot support portions (66) and (76). Each safety engagement assembly includes an abutment arm (106) and (116), and a curved attachment link (104) and (114), which together prevent the derailment of the foot link rollers (68) and (78) from the guide tracks (42) and (52).

Title: Chain saw adjuster
Inventor: WARFEL PAUL
IPC: B27B17/02
Filed: 2001-11-14
Granted: 2008-09-16
Abstract: An arrangement that provides a semi-automatic tension adjustment of an endless cutting chain on a guide bar of a chain saw as the links of the chain wear with use. A specially designed cam biases a tensioner pin to continuously force the guide bar away from the drive sprocket on the engine chassis to tension the chain. A knob on a clutch cover assembly attached to the engine chassis can be tightened to force two high friction surfaces together to lock the guide bar in a tensioned position, or loosed to release the guide bar to seek a proper tensioned position. An override lever on the face of the clutch cover assembly moves in a channel with peripheral nomenclature that indicates when the cutting chain should be replaced. The entire arrangement is self-contained and does not require any tools to function.

Filed: 2000-03-06
Granted: 2008-07-29
Abstract: Cette invention concerne la production de pigments de dioxyde de titane de qualité supérieure par retraitement organique double consistant à appliquer un composé organique (I), servant d'adjuvant de broyage, sur les particules non traitées ou déjà retraitées organiquement, avant le broyage final, puis à appliquer un composé organique (II) servant d'adjuvant dispersant et mouillant spécial, après le broyage. Ces pigments sont particulièrement adaptés aux laques en dispersion à haut brillant qui sont diluables dans l'eau. Une adaptation du composé organique (II) sur la matrice par modification du rapport hydrophile/lipophile n'influe plus sur le degré de broyage, mais influe de façon positive sur le degré de répartition des particules de pigment dans la matrice et conduit ainsi à une meilleure dispersion et à une brillance plus éclatante.
