An ink jet printing system comprising a droplet generator ( ), a supply tank ( ), supply transfer means for driving the ink from said tank to said generator and means for measuring the flow rate of the stream of ink droplets by monitoring the change of ink level in said tank, said system including a bleed connection ( ) from the generator to the tank in closed circuit with said tank. An ink jet printing system comprising means for using measurements of the rate of change of liquid level in an ink supply tank to provide an indication that there has been a fault in the system. An ink jet printing system comprising a holding tank ( ) for receiving liquid issued from the ink jet generator during preparation of the system.

Ink jet printing system

An evaporation tray for a refrigerator or refrigerator/freezer which is adapted in use to contact a heat producing part of the refrigeration system (such as the compressor or condenser). The tray comprises a rigid frame which supports a flexible membrane designed to receive defrost liquid from the refrigerator or refrigerator/freezer. The frame is designed to sit adjacent the heat producing part so that the flexible membrane is in direct contact with the heat producing part. As the membrane is flexible, it easily deforms to the shape of the heat producing part providing increased heat transfer to liquid in the tray.
