Abstract: The invention provides a compact automatically operating distillation apparatus comprising a baseplate that will free-stand, but is more usually located on a reservoir to receive the distillate, which usually is water. A boiler container having an electric heater is removably mounted on a support, which is movably mounted on the baseplate with the weight of the container and the water opposed by a spring. The support operates electric switches that open a solenoid-operated valve to supply water to the boiler when its weight decreases a predetermined amount, and that will switch off the heater if the boiler has insufficient water. The output of the boiler goes to a condenser coil which is supplied with cooling air by a fan. A float in the reservoir controls another switch that will stop operation when the reservoir is full.

Abstract: A machine for washing drinking glasses has a conveyor upon which the glasses are conveyed from a loading zone through wash and rinse zones to an unloading zone. The machine may be operated on a continuous basis or it may be operated on a timed cycle basis, or it may be operated intermittently, being stopped by detector mechanism sensing the arrival of a glass at the unloading zone.

Abstract: A dishwasher of the batch type is provided with vent means to atmosphere to relieve pressure build-up in its interior. The vent means consist of a vent structure disposed to one side of a front-opening door, preferably one on either side, this structure providing a horizontal vent passage that intersects a vertical drain passage leading to the dishwasher sump. The structure is formed by three elongated members of various shapes, that fit together to provide two separate drain channels of the drain passage, and that also provide a channel receiving and supporting the door side sealing gaskets.
