Abstract: The vented refuse can consist of a unique component accompanying the open top receptacle where trash bags are inserted and removed. The component that makes this present invention unique is the openings located in the upper part of the receptacle's sidewalls, which allow trapped air between the receptacle and the trash bag to be released. The trapped air being released will prevent bag tearing and slipping off the rim of the receptacle, which will reduce the number of wasted trash bags due to rips and holes caused by the trapped air when trash is tossed into the receptacle.

Abstract: A shaft seal system for watercrafts, where a seal from the system may be replaced while the watercraft is in water. The invention comprises two seals, one at each end of a cylindrical member having cooling and lubrication means. Water enters an entry port and circulates throughout camera channels within the cylindrical member and around a shaft which drives the watercraft propeller. The water then exits an exit port. The cylindrical member has a removable ring at one end, which keeps the first seal pressed in place. When the first seal deteriorates and needs to be replaced, the exit port water line is disconnected to determine if the second seal is in satisfactory condition. If the second seal is preventing water from entering the camera area, said ring is removed. A replacement seal already upon the shaft is slid in place, and said ring is re-secured. If the second seal is not in good condition but only a small amount of water enters, the replacement of the first seal may still take place.

Abstract: A device usable as an applicator comb, comprising a collection of applicator teeth inserted into a tubular body (1) as supporting element, permitting liquid or gelatinous products to be applied precisely and economically, by having attached to the device a container or receptacle holding the treatment product. For hair and scalp treatment, the product enters the applicator teeth (2, 2I, 2II, 2III, 2IV, 2V. The product to be applied may cover all, only the sides or only the base of the applicator teeth, depending on whether the treatment is to be given on the totality of the hair and scalp, only on the hair, or on the base of the hair and in the scalp. Depending on the application, the tooth structure has a rigid core constituting the support for a permeable, peripheral cladding (13), or only a lateral cladding (12), without reaching the end.
