Abstract: A toy has a housing in which is rotatably supported at least one disc having a plurality of object members on it. The object members are fixed to the disc and therefore movable with it. The toy includes a motor which drives the discs via a clutch. The clutch has two positions, one an engagement position wherein the disc is driven and the other a non-engagement position wherein the motor is no longer capable of driving the disc. A movable member is mounted on the housing and positioned in association with the disc. By moving over the surface of the disc, the movable member is capable of individually contacting each of the obstacles on the disc and upon such contact, the movable member is capable of interlocking with each of the obstacles to stop the rotation of the disc and shift the clutch into the non-engagement position where it remains until otherwise acted on.

Abstract: Method and apparatus for making tea or coffee for drinking comprising heaping tea in an extractor and subjecting successive areas of the heaped tea to periodic sprinkling during successive intervals of sprinkling, with cold tap water, each followed by intervals of wet-expanding the tea until the tea is substantially completely wet-expanded. The sprinkling intervals are timed to allow the wet-expanding to take place after each sprinkling of a same area and without collapsing of the wet-expanded tea. The tea resulting from the wetting is filtered out while removing air bubbles therefrom. The extractor has a sprinkler continuously driven during the sprinkling period and the filtrate is taken out through a pipe perforated axially extending into a filtrate-receiving container. The filtrate is delivered as a tea drink and may be stored in a glass container or the like for prolonged periods without loss of flavor.
