Patent CA-2441143-A1 (CA)
Title: Personal swim craft with an underwater viewing area
Inventor: HARKRIDER KENT
IPC: B63C11/49
Filed: 2003-09-16
Abstract: A personal swim craft that has a liquid filled viewing area that is simply and inexpensively created within the craft requiring no tooling for molds or related costs. A walled cavity through the craft is sealed at its upper and lower openings with transparent panes. These panes are sealed in place without drilling or tapping holes or otherwise altering the surface area of the panes. The void between the transparent panes is filled with a transparent liquid via a vent that can be within the upper transparent pane or integrated into the craft adjacent to the upper pane and extending through the craft into the cavity void. The upper pane of the viewing area is slanted aft to allow extraneous water to run off into scuppers or vertical vents adjacent to the aft perimeter edge of the upper pane. These vertical vents and a forward set of vertical vents also remove air bubbles that may become trapped below the outer surface of the lower transparent pane. The transparent liquid, which could be within the viewing area cavity, is in essence a column of transparent liquid that rises above the level of water in which the craft is launched with the bottom pane of the viewing area within that water. The transparent liquid extends upward within the cavity to the upper transparent pane atop the craft. When a user lies prone on the craft, their forehead rest upon a head support placing the eyes over and within inches of the upper pane.  The users head and face are not confined nor is peripheral vision restricted, making it safer to use. The user can lie prone or transposed upon the craft with head, neck, shoulders, arms, and back supported by the craft in an ergonomically stress free manner, best replicating that of a person floating in water. The craft with underwater viewing area can be used by the vast majority of people regardless of age, sex, or physical condition.

Title: Procede permettant d'augmenter le rendement des pois independamment du temps
Inventor: HIROSE ISAMU
IPC: A01G1/00
Filed: 2001-06-01
Abstract: L'invention concerne un procédé permettant d'augmenter le rendement des pois indépendamment du temps, qui consiste à bien faire pousser des graines de pois jusqu'à un certain stade et, à un stage précoce d'égrenage à couper les feuilles et les tiges latérales absorbant sans nécessité des substances nutritives, de sorte que ces substances peuvent ensuite être exclusivement utilisées pour la croissance des pois. Grâce à ce procédé, les gousses mûrissent plus tôt et contiennent des pois bien mûrs même au niveau de la partie supérieure. Après germination des graines de pois semées, lesdites graines poussent. Lorsque des gousses se forment sur les tiges inférieures, on coupe les tiges dépassant lesdites gousses et les feuilles qu'elles portent. On peut utiliser les substances nutritives de manière plus intensive pour faire mûrir les pois dans les gousses.
