摘要： 333,334. Nicoll, D. July 9, 1929. Cream, separating.- A device for removing cream from milk in bottles, in the form of a container adapted to be inserted into the bottle neck, consists of two interfitting tubes each provided with an opening therein, the tube being adapted to be moved relatively to bring the openings into coincidence to allow the cream to enter the container and then to be displaced relatively to close the container ready for removal, with the cream, from the bottle. As shown, the openings A, B are in the lower ends of relativelv rotatable tubes R, S, the inner tube S being adapted to beturned by a removable cap T, Fig. 5, and the outer tube R being provided with a head C to engage the bottle mouth. The inner tube has a projection F adapted to engage a bayonet slot E in the outer tube.

摘要： A modular step system for in-ground swimming comprising a bottom central hub, a brace assembly, a top central hub, a tread support assembly, a step form and a liner. The components of the modular step system interlock and snap together without fasteners. Also, the components of the modular step system are obtained by molding plastic material or curing of a curable material. The modular step system is installed on a level concrete floor of a swimming pool and designed to be rigidly fixed from behind to adjacent pool walls. The modular step system is adaptable to a pool having a vinyl liner, structurally sound regardless of size, easy to assemble, consistent in size, and cost-effective.
