Abstract: A cooking appliance may include an oven cavity having a cavity top, a cavity back, and cavity side walls, an interior side wall extending parallel to each of the cavity side walls defining a passage therebetween, and a plurality of side rails extending along the interior side walls, the rails being rotatable between a rest position in which no oven rack is installed and airflow is blocked, and an active position in which the oven rack is installed and airflow is provided.

Abstract: Disclosed is a nut welding automation system configured to automatically weld different types of nuts to holes formed in a metal-processed product using a robot. The system may reduce an error rate with respect to products by preventing omission of a nut or welding of a wrong type nut so that reliability in administration of the welding process may be secured and overall productivity may be improved.

Abstract: A detector is configured to detect an output of a reflected beam from an exit end surface of a parallel plate. A determination unit is configured to determine that an abnormality occurs in the parallel plate when a detection value of the detector is smaller than a determination threshold.

Abstract: A milk frother/heater for a milk supply circuit in a beverage vending machine has a hollow body and integrally has a first appendage defining a milk inlet to receive smooth milk or a milk-air mixture, a second appendage defining a steam inlet to receive steam, and a third appendage defining a milk outlet to deliver milk. The body internally defines a mixing chamber, and the milk inlet, the steam inlet and the milk outlet internally define a milk inlet passage, a steam inlet passage, and a milk outlet passage, respectively, fluidly communicating with the mixing chamber. The mixing chamber has an axis extending from a first closed axial end to a second axial end where the steam inlet passage and the milk outlet passage converge. The milk inlet passage converges at the second axial end or merges with the steam inlet passage upstream from the mixing chamber.
