Abstract: An apparatus for producing soft serve dairy products, especially yogurt, and comprising a freeze barrel having an inlet spaced about one-fourth of the barrel length from a rear end wall of the freeze barrel, and a beater shaft assembly which includes a square shaft, at least four blade elements mounted on the four faces of the square shaft, respectively, and four pairs of spaced pins projecting a successively radially from the four faces of the square shaft for supporting the four blade elements, respectively, on the shaft and arranged along the shaft with a first pin of the first pair of pins being located about halfway between the rear end wall of the barrel and the barrel inlet and with a first pin of each successive pair of pins except the second pair of pins being spaced slightly beyond a second pin of a preceding pair of pins in a direction toward the front end wall of the freeze barrel.

Abstract: An electric outlet cover comprises a base plate having at least one opening and locking means, a cover plate hingedly connected to the base plate for covering an electric outlet when the outlet is not used, and at least one supporting means connected to the cover plate. The base plate is adapted to be disposed adjacent to the electric outlet so that the outlet registers with the opening for insertion of an electric plug into the outlet through the opening. The cover plate includes a closure element adapted to engage the locking means when the cover plate is placed over the base plate. The supporting means is adapted to support an insulated electric conductor when the electric plug connected to the conductor is received in the outlet so that the plug is retained in the outlet despite unintended movement of the wire.
