Abstract: A heating apparatus is provided for heating a medical product such as a bag of frozen plasma or blood. The apparatus includes a reservoir for holding a supply of heating liquid. At least one heating compartment is provided for holding a bag of frozen plasma or blood. At least one bladder is disposed within the heating compartment for engaging the medical product within the heating compartment and for receiving heating fluid from the reservoir to heat the medical product. A controller is provided for controlling the heating of the medical product. A heater operates under the control of the controller for providing heat to the heating fluid. A pump operates under the control of the controller for pumping the heating fluid from the reservoir to the bladder to effect heat transfer to the medical product in engagement with the bladder. A rocker operates under the control of the controller for agitating or rocking the medical product within the heating compartment to facilitate thawing of the medical product.

Abstract: A film developing apparatus is provided for developing photographic film by an automated batch process. The apparatus provides automated preparation of precise mixtures of the processing liquids at various stages of the batch process. The mixtures are made on-demand and are pre-heated just before use in the batch process. Additionally, the apparatus provides a method to reuse used processing fluids in future processing. In particular, the apparatus makes use of its mixing capability to combine a reserved processing fluid with a fresh processing fluid to create a replenished processing fluid.
