Abstract: A low inclination push back storage rack system is described, the system having a plurality of storage lanes, each storage lane being equipped with one or more rectangular carriages to transport a pallet load from a front loading position to a rear storage position. Each carriage is provided with axles on which wheels having notches about their peripheral circumference are mounted. The wheels are typically V groove wheels. The V groove wheels of each carriage roll on parallel spaced apart rounded elongated rods, the V groove wheels on one side of the carriage rolling on one elongated rod, the V groove wheels on the other side of the carriage rolling on another elongated rod. The carriages wheels are supported and guided by the elongated rounded rods. The spaced apart parallel rounded elongated rods are supported by spaced apart rod support members extending from the front of the storage lane to the rear of the storage lane.

Abstract: A plug-in cold storage assembly capable of being moved from one insulated cabinet or chest to another, including at least two spaced "holdover" cold storage units and a mounting structure that holds the storage units in spaced relation and which completes flow connections between them and permits mounting in a cabinet or chest.

Abstract: A portable cooling chest having a durable outer shell and an inner liner, each with bottom and side wall members, includes a unitary middle liner arranged in proximity to the bottom and side wall members of the outer shell to define an insulating compartment and in proximity to the bottom and side wall members of the inner liner to define a sealed cavity circumscribing the inner liner and containing eutectic fluid and immersed heat exchange coils. The heat exchange coils, coupled through a quick connect/disconnect means to the refrigerant of an automobile refrigeration system, circulate chilled refrigerant to chill and freeze the eutectic fluid within the sealed cavity and cool the interior space of the cooling chest.
