Abstract: A cheesemaker with a container interior in the form of a cheese vat or cheese kettle, which rotatably incorporates a driven agitator with at least one agitating and cutting blade. The cheesemaker is to be simple in structural design and easy to operate, and also satisfy strict hygiene requirements. This is achieved by providing the agitating and cutting blade with a window that can be detached therefrom, and moved relative to the agitating and cutting blade.

Abstract: Disclosed are weld electrode plugs with polymeric inserts for loss-of-cooling detection, methods for making or for using such weld electrode plugs, and electric welding systems equipped with loss-of-cooling detection plugs. A disclosed loss-of-cooling detection assembly includes a plug that attaches to the weld shank of a welding system such that the plug fluidly couples to a coolant bore within the shank. The plug includes a plug body with a clearance hole extending therethrough. An insert detachably mounts to the plug such that the insert fluidly seals the clearance hole. This insert is fabricated from a polymeric material, such as a shape memory polymer, that alters a physical property, such as shape/size, of the insert responsive to changes in temperature and/or pressure of coolant fluid in the shank's bore. When this physical property is altered, the insert unseals the clearance hole causing a detectable leak of fluid from the shank.
