Patent CA-2538811-A1 (CA)
Inventor: CEZEAUX THOMAS EDWARD
IPC: B65D47/32
Filed: 2004-09-07
Abstract: A hydration system is disclosed for carrying readily dispensable fluids, such as water. A removable cap having an annular valve covers a container. A  flexible tube is disposed through the center of the annular valve and extends generally to near the bottom of the container. A bite valve is attached to the end of the tube that is external to the container. When the annular valve is closed, the hydration system is substantially closed, preventing fluid loss.  When the annular valve is opened, an air channel is created that allows air to enter the container, facilitating the flow of fluid from the container through the flexible tube. The annular valve may be a poppet-type valve having a valve stem that is movable between the closed position and the open position. The hydration system is sufficiently compact to be utilized with narrow-mouthed bottles.

Patent CA-2543776-A1 (CA)
Inventor: SCHREIBER STEFAN
IPC: G11B7/24038
Filed: 2004-10-27
Abstract: The invention relates to an optical data carrier which combines a CD layer with at least one further format, such as a DVD layer for example. If a hybrid data carrier of this kind is to be produced in a thickness of less than 1.7 mm, and preferably in a thickness of 1.5 mm or less, then, seen from the surface which is to be read from, the CD layer will normally be situated at a depth of considerably less than 1.1 mm, and the CD substrate therefore has to be thinned down. The quality of the reading signals obtained is increased by increasing the length of the optically readable structures of the CD layer in comparison with the values which are usual in this case. Because of the difficulties which certain CD players have in focussing when the substrates are thin, the refractive index of the disc material used is reduced from the figure for polycarbonate, at least in the case of the CD substrate, the recommended range being between 1.40 and 1.55. The compatibility of the CD layer of a hybrid disc according to the invention with different players may be further increased by widening its readable structures in comparison with normal values and thus by making them more than 500 nm wide.
