Abstract: A supplemental refrigeration heat sink includes a plurality of sealed tubes filled with a compound and arranged so as to extend across the top inside a refrigerated box. The compound is preferably a phase change compound with a melting point proximate to and higher than the average return air temperature. During the cooling phase of the box, the supplemental heat sink tubes are cooled, with the phase change material freezing or nearly freezing. During the heating phase, cooling fans can be secured and the phase change material readily absorbs heat from the box, slowing the temperature rise in the box.

Abstract: A neck movement support device includes a stationary member, a movable member connected to the stationary member and rotatable relative thereto about an anteroposterior neck movement axis, a yoke extending away from the movable member and rotatable therewith about the anteroposterior neck movement axis, a handle connected to the yoke and rotatable relative thereto about a mediolateral neck movement axis, and a head hardness connected to the handle and rotatable relative thereto about a craniocaudal neck movement axis. A head of a user is securable to the head hardness, so as to constrain the head to move or remain stationary along with the head hardness about the anteroposterior, mediolateral and craniocaudal neck movement axes.

Abstract: In an earth planting process which entails the boring and refilling of a hole, a method and apparatus are provided to accumulate extracted soil in a container whose configuration is defined by two rigid and concentric cylinders which are joined by a flexible membrane. Raising of the outer cylinder causes the container to assume a funnel shape so that it can be used to pour the extracted soil back into the hole after the removal of a boring tool and possible placement of a plant, post or other object in the hole.
