Abstract: A waste energy hot water heater which extracts heat energy through heat exchange with flue gas from a primary heating device is disclosed. The water heater has an easily removable, compact, and simple heat exchanger and a flue gas bypass system to avoid overheating the heat exchanger.

Abstract: The apparatus comprises an enclosure for receiving ice chips and water and a specially designed and dimensioned mixer in the form of a vertical shaft passing into the enclosure and supporting two sets of four turbine blades each. Further, the interior of the enclosure includes baffles spaced radially inwardly from the interior wall to leave a small gap between the wall and each baffle. The resulting violent agitation enables the provision of "liquid ice" without any necessity to add salt as has been required in the past.

Abstract: The apparatus is for pre-cooling produce immediately after harvesting of the same and towards this end, constitutes a portable elongated enclosure normally positioned at the field site of harvesting. A detachable dolly supports the enclosure so that it can be moved to various different field sites as required. The enclosure itself supports pallets having containers arranged in two longitudinal rows to define a passage therebetween. An air handling housing in turn incorporates an exhaust fan, cooling coils and appropriate ducting so that refrigerated air is circulated over the tops and sides of the rows of the containers and drawn into the central passageway by the exhaust fan to then again pass into the air handling housing. In other words, a forced air circulation is used to remove the field heat from the containers.

Abstract: The broccoli bunching apparatus is wholly pneumatically operated. In response to a first operation on a manual pneumatic control switch, a rubber band is pneumatically expanded in front of a central opening in a housing. Broccoli stems can then be inserted through the rubber band and the opening. A second operation of the pneumatic control switch results in the rubber band retracting about the stems and simultaneously a knife blade within the housing cutting the stems. Also, an ejector is automatically operated after a given delay time to strip the cut broccoli stems from the rubber band expander so that the apparatus is ready for repeating the operation.

Abstract: The icing apparatus comprises an open frame structure for receiving cartons stacked in rows and columns on a pallet. These cartons contain perishable food such as broccoli brought in from the field and are to be treated with liquid ice to preserve their contents. Towards this end, the apparatus includes left and right carriages carrying horizontal rows of liquid ice injecting probes or nozzles. These carriages can move up and down left and right sides of the frame and also the probes themselves can be moved in and out towards and away from cartons on the pallet. By this arrangement, an upper horizontal row of cartons can be simultaneously iced by the horizontal row of probes by simply moving the same into the hand hold openings of the cartons. The carriage structures can then be lowered by the heighth dimension of the cartons and a next horizontal row of cartons simultaneously treated with liquid ice.

Abstract: The liquid ice system comprises an icing machine in the form of a compartment for receiving water and ice. Pulverizing means are provided for crushing the ice and uniquely oriented paddles stir the water and ice mixture to maintain a homogeneous mixture of liquid ice. A circulating conduit is provided in combination with a conveyor system and ice applicator devices connected to a portion of the conduit supported on an overhead structure of the conveyor. Boxes of vegetables or poultry are appropriately refrigerated for shipment by applying liquid ice to the boxes as they pass along the conveyor. Switches may be provided for automatically actuating the ice applicators when the box passes therebeneath.

Abstract: An attachment or, accessory water heater being installed in any furnace flue, or pipe giving off an exhaust heat. When installed in a flue or pipe and connected in conjunction to any type self-sufficient water heater tank. It is the purpose of this invention, to use the heat which escapes up the flue from the furnace during operation. Thus eliminating in most cases, and drastically reducing in others, the need for additional energy, which is normally used to heat water. The accessory heater is essentially a condensed unit, which divides water into multiple and smaller parts, comprising a conduit of two sizes, being formed and shaped into condensed spiral coils, and connected to rings or headers, and circulating water through the unit and back to the tank, by means of convection or pump.
