Abstract: A system for automated batch blending of materials such as liquid fertilizers is disclosed. Liquid and dry products are supplied to a product mixing holding tank by way of valve-controlled inlet lines. A control panel responsive to the weight of the material added to the holding tank regulates the operation of the valves and of a recycling pump which mixes the product. The system permits small quantities of product to be produced under automatic control.

Abstract: A multi-purpose kitchen appliance having two pairs of output spindles with each pair being driven at different preselected speeds, one pair of said spindles having dough hook receiving bores and the other pair having mixing beater receiving bores, a turntable-supported bowl with said dough hooks and said mixing beaters being selectively disposed in said bowl for mixing material therein, interlock means preventing simultaneous driving engagement of said dough hooks with their spindles and said mixing beaters with their spindles, and means for selectively ejecting said dough hooks and said mixing beaters from said pairs of spindles.
