Abstract: A food mixer includes a dual mount sensor arrangement which prevents operation of the mixer unless a protective safety guard is secured to the mounts. Each mount is physically spaced from each other so that a user must take extraordinary, and deliberate measures to circumvent the safety feature. The dual mount arrangement may be used in conjunction with a bowl lowering shut-off feature for disabling the mixer when the mixing bowl is lowered to a position where the user's safety is at risk.

Abstract: A removable, washable air filter apparatus is formed with two V-shaped rectangular mesh filters held in place side by side within a housing with the vertices of the V filters draining grease and moisture into a removable pan. A mounting bracket maintains the pan in position to receive extracted grease and moisture without impeding air flow through the exposed filter mesh. The top edges of the housing have outwardly formed flanges for removably mounting the housing by means of overlying swivel retainers provided around the periphery of mating flanges on an intake opening of a ventilation hood or air duct.

Abstract: Circuit breaker apparatus with two parallel formed terminals secured by metal screws to a dielectric body receiving a male thermocouple head threaded against the first metal screw with a tubular threaded male portion at the other end of body with tubular opening having a compression spring contacting the second metal screw and extending beyond the male portion providing electrical contact as the male end is threaded into a female thermocouple opening of a low voltage control with circuit break between the two parallel formed terminals providing for a second control function to be interposed within a low voltage thermocouple operated circuit.

Abstract: Temperature limit control having a normally closed contact switch secured to a formed cup with vacuum operated formed diaphragm seal to cup bottom, contacts open on reduced vacuum as by boiling thermal fluid in the linear capillary tube welded to the cup below the diaphragm or boiling of fluid in a sensor bulb welded to the capillary tube end for remote temperature control, with vacuum leakage within lower cup, diaphragm, capillary tube and, or, sensor bulb releasing diaphragm from its pulled down position against inward formed dimples between the cup side and central outlet likewise opening contacts providing fail safe operation.
