  • Patent number: 4382304
    Abstract: A new article of manufacture, comprising a capsule intended to be dropped into the water tank of a toilet, to dispense metered amounts of a chemically active cleaning agent into the water over a long interval of time. At the end of such interval, the entire capsule has been substantially completely disintegrated and flushed away whereby its removal is not required, notably when a new capsule is to be dropped into the tank. The capsule comprises a container made of material which could be metal containing aluminum, that very slowly disintegrates under the action of the chemical cleaning agent contained therein at such time that the chemical becomes mixed with water. The capsule has one or more stoppers for water access openings, or has other means to enable water to enter it for acting on the cleaning agent. If stoppers are provided, these are removed prior to dropping the capsule into the tank. The chemically active cleaning agent can comprise the hypochlorite of an alkaline metal such as sodium or calcium.

  • Patent number: 4337000
    Abstract: A planetary-type kitchen mixer-kneader having two spindles both of which turn in the same direction and travel in identical circular orbits as they sweep in an orbital path along the inside wall surfaces of the mixing bowl. The spindles are adapted to carry wire whips, flat beaters, and dough hooks, the latter in pairs which cooperate by means of their shapes and deflector blades, to simultaneously mix and work the dough and retain it low in the bowl.
