Abstract: Automobile windshield wiper apparatus wherein transmission linkage ball stud coupling combinations employ flat surfaces on facing linkage members in the area of each coupling cooperating with a polymeric one-piece socket bushing having a sealing skirt portion providing a lubricant seal.

Abstract: A refrigerator cabinet water storage tank is oriented horizontally on the floor of the fresh food compartment and includes first and second side-by-side water storage chambers interconnected by a cross-over passage having a continuous taper which constantly increases the cross-sectional areas from the first chamber inlet to the second chamber outlet. The tank allows the water to enter from a domestic water source at a point lower than the exit tube outlet with the outlet arranged at the tank's highest point obviating the entrapment of air within the tank. The tank has an internal configuration providing maximum internal volume while fitting into a limited space. The water flow through the tank follows a serpentine U-shaped path to promote water turbulence which will provide maximum heat transfer.

Abstract: A beverage concentrate and water dispenser for a household refrigerator cabinet wherein multiple spouts with individual actuating and mixture diluting means are accessible from the exterior of the refrigerator cabinet. The dispenser includes a plurality of valves, fed with chilled water via a manifold from a water storage tank within the cabinet, for flow through jet nozzle aspirator means, operative for drawing beverage concentrate through a suction tube for mixing with the water prior to being dispensed. The dispenser concentrate-water mixture diluting means includes a valve in a water bypass passageway for selecting the proportion of bypass water dilution desired to be added to the concentrate-water mixture. An electrical switch is operative in sequence with resiliently biased valve plug members to delay the admission of source water under line or water main pressure into the manifold until the selected valve plug has been unseated.
