Abstract: A toilet includes a toilet tank, a toilet base, at least one coupling receptacle connected to the toilet base, at least one coupling anchor connected to the toilet tank, and at least one flexible collar lock connected to the at least one coupling anchor and configured to flex inwardly in response to contact with the at least one coupling receptacle and flex outwardly to lock the at least one coupling anchor and the toilet tank to the at least one coupling receptacle and the toilet base.

Abstract: At least one embodiment relates to a quick-coupling mechanism including a clamp spring configured to receive a valve body. The clamp spring is coupled to a release button configured to manipulate one or more arms of the clamp spring. The quick-coupling mechanism includes a base structure coupled to the toilet pedestal/bowl. The base structure is configured to hold the clamp spring in place. In a locking-state, the clamp spring seats in a groove in the valve body thus securing the valve body in place and preventing an axial movement of the valve body relative to the clamp spring. In a non-locking state, the release button bends the arms of the clamp spring outwardly to increase the diameter of the clamping portion, thus releasing valve body such that the valve body can move axially relative to the clamp spring.

Abstract: A flush actuator assembly for a plumbing fixture includes a housing, a handle and a lever. The housing is configured to be removably coupled to the plumbing fixture. The handle is pivotally and removably coupled to the housing. The handle includes a stem configured to extend through the plumbing fixture and into the housing. The arm is removably coupled to the stem within the housing. The arm is configured to pivot with the handle. The lever is at least partially disposed in the housing, and is configured to be selectively disengaged from the stem to removably couple the handle to the housing.

Abstract: Provided are systems, methods and computer programs for generating comparison information for all course books, regardless of whether or not the books are required or optional, for multi-course student schedules. Also provided are systems, methods and computer programs for transacting sales between sellers and buyers of course books and online products, wherein the sellers and buyers may be online or offline and the online products may have a standardized product identification number.

Abstract: A flush valve for a toilet has a valve body with a flow passage that narrows non-linearly down from the valve seat. The flow passage is formed by a surface that follows a polynomial expression so as to define a computationally derived flow profile that more closely follows the narrowing exhibited by falling water as it accelerates under gravity. The non-linear flow profile of the valve reduces the presence of air in the valve after a flush cycle is initiated so that greater flush efficiency can be achieved. The flush valve can also have a wide mouth overflow that narrows to improve flow in an overflow situation.

Abstract: A mount assembly releasable mounts a toilet seat and cover to a toilet base. The assembly includes two fasteners permanently affixed to the toilet base engaged by deflectable arms of one or two base members of the mount assembly. The arms engage ring mounts disposed about the fasteners, flexing outward slightly during mounting and dismounting achieved by a simple horizontal sliding motion. When connected, hinged covers snap onto the pair of arms to cover the fasteners and prevent deflection of the arms and thus separation of the base member(s) from the fasteners.

Abstract: A mounting assembly is disclosed for mounting a toilet seat and/or cover in a releasable fashion to the rear of a toilet bowl base. The assembly includes a fastener permanently affixed to the toilet base on which is mounted a cross shaped mount. The mount is engaged by deflectable arms extending from a hinge base. The arms flex outward slightly during mounting and dismounting, where mounting and dismounting can be achieved by a horizontal sliding motion. A hinged cap snaps onto the pair of arms to cover the fastener and prevent deflection of the arms and thus separation of the base member from the fastener.
