Abstract: A cold pack comprises a main body; an inner chamber defined by the main body; and a phase changeable medium disposed in the inner chamber. The phase changeable medium includes a polymer and a peptide, which can be a component of a peptide-containing composition. In specific examples, the polymer is an organic polymer, such as an organic superabsorbent polymer, and the peptide is a lateral root hair promoting peptide.

Abstract: A refrigerant bunker comprises a refrigerant covering comprising a first thermally insulating material configured to enclose a solid refrigerant and an outer container comprising a container body and a container cover. The container body comprising an outer surface, an inner surface defining a partially enclosed space configured to accept the solid refrigerant and an opening for accessing the partially enclosed space. The container cover is configured for covering the container opening. The container body comprises a second thermally insulating material. A plurality of spacers protrude from the inner surface of the outer container in the partially enclosed space. The plurality of spacers are positioned to have gas fillable gaps between the spacers. Coolers employing the refrigerant bunker are also disclosed.

Abstract: An article of manufacture for use as an insulated overhead door that is designed to roll open and closed in tracks, with a sheet of thermoplasitc material that acts as the outer door membrane and barrier to entry, a sheet of insulating material that acts as a base insulating barrier adhered to the thermoplastic membrane.

Abstract: A system for maintaining thermal separation between first and second adjacent rooms or spaces. The system includes a vestibule with at least a first compartment, and other embodiments may include two or more compartments, such that the vestibule provides a passageway between the first and second rooms. At least one blower draws air from the first room through an air intake, and back into the first room through an exhaust. The system further includes an exhaust port from the first compartment in fluid communication with the exhaust, to exhaust air from the first compartment into the first room. During operation, a vacuum is formed within the first compartment that provides thermal separation between the first and second adjacent rooms.

Abstract: A trailer overhead door system for a truck or trailer having a door opening. The trailer overhead door system having a trailer door for enclosing the door opening and a counterbalance system for counterbalancing the trailer door. The counterbalance system including a lifting cable and a return pulley for guiding the lifting cable. The lifting cable attaching between a door top rail, around the return pulley, and back to the counterbalance system.

Abstract: A pneumatic door system and a method of using the same are disclosed herein. According to one embodiment, a trailer may include a seamless main door and at least one side door. The doors may be configured to be locked shut with a system of pneumatic locks. The main door may be configured to open and close as controlled by pneumatic pressure applied to a door cylinder. The pneumatic system may be configured to be controlled by an interior control box. The pneumatic system may be configured to operate off of pneumatic pressure in an auxiliary air tank, the pressure being protected by a series of one-way check valves. The pneumatic system may also be configured to operate wirelessly using RFID or Bluetooth technology, among other things, to secure the cargo and facilitate ingress and egress to the trailer.

Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move out of the track. The release assembly includes a biasing mechanism that allows the assembly to flex and ride out of the track when the door is impacted.

Abstract: A method for adjusting pressure at an inlet of a blast freezer. The method includes positioning an airfoil proximate to the inlet, the inlet having a perimeter. The airfoil includes a strip of material having a length and being attached to the freezer along at least one side of the inlet, the strip of material being spaced from the perimeter of the inlet by an offset distance. The offset distance at any location along the length of the strip of material is the closest distance between the strip of material and the perimeter at that location. The offset distance varies substantially along at least a portion of the strip of material. Cold air is flowed in the blast freezer past the inlet and over the airfoil so that the flow of air past the inlet is disrupted and creates a resultant adjustment to the air pressure at the inlet.

Abstract: A system for allowing a loading dock door to release from guide tracks. The dock door includes wheel-and-axle assemblies which are mounted to the door and which include wheels biased towards a position in the tracks. At least one of the tracks has a cross sectional profile which enables the wheels disposed in the one of the tracks to move out of the one of the tracks when the door is struck with sufficient force.

Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow the wheel assembly to move up the sidewall and out of the tracks, and a tensioned or spring loaded wheel assembly that allows the assembly to flex enough to ride up the sidewall and out of the tracks when the door is impacted.

Abstract: A flexible door panel cold storage door system incorporates a flexible movable door panel having an internal support frame assembly and the door panel has a plurality of gasket sections removably attached to a cold space surface of a door panel jacket with each gasket section having at least one ferrous gasket target and the gasket sections are aligned and cooperate with a plurality of electromagnets that are mounted in a doorframe assembly when the door panel is in a closed position. The electromagnets are mounted in wells in the doorframe assembly and are powered on when the door panel is in the closed position and the wells are interconnected by a ventilation channel that conducts air heated by operation of the electromagnets through the ventilation channel and into and through a bottom sweep assembly of the door panel in a closed loop.

Abstract: A portable active cryo container for maintaining product at refrigerated and/or cryogenic temperatures. Said container comprising a control system to monitor and control the flow of cooling air from a bunker section to at least one material storage section wherein temperature sensitive product is contained.
