Abstract: In appliances for practicing aquatic sports with water flowing upwardly over a sloping bottom surface a premature breakdown of the flow caused by the accumulation of portions of water slowed down by friction at the boundary faces is prevented by at least partially removing said portions of slowed down water. This can be done by sucking off at least the increasingly portions of slowed down water which are preferably refed to a return pipe of the appliance. A further possibility provides that portions of slowed down water are accelerated by supplying water at an increased flow rate. Suction of the portions of slowed down water as well as the supply of water at an increased flow rate is particularly effected through apertures in the bottom surface in the regions in which the portions of water are particularly slowed down, i.e. above all in the regions in the vicinity of an overflow at the upper end of the sloping bottom surface.

Abstract: The carousel when assembled by the consumer has striking animation effects (considering that the mechanism is made primarily of wood), including a rocking motion of animal figurines. The rocking results from mounting each figurine on the end of a horizontally rotatable shaft, supported from the carousel; a crank keyed to the same shaft extends down through a log slot in the carousel deck.Under the deck is a stationary disc. In this disc is a series of holes, in a circular pattern with radius equal to that of the crank locus. The crank periodically drops into these holes, as they sequentially move under the crank; the crank rotates upwardly as the trailing edge of each hole sequentially engages the crank.This oscillation of the crank is transmitted by the horizontal shaft to the figurines.
