Abstract: An airform that can be inflated, for example, for facilitating construction of a structure is provided. The airform may include a first portion, a second portion, or multiple other portions, and reinforcement. The first portion may, for example, be configured to be disposed in a first orientation, such as vertically or in a radial profile, when the airform is inflated. The second portion transitioning from the first portion may be configured, for example, to assume an alternate shape and profile, such as a radial shape and profile, when the airform is inflated. The reinforcement may, for example, be provided at a portion of the airform that defines a transition from the first portion to the second portion.

Abstract: An icemaking assembly (“icemaker”) is provided which includes an improved construction including an ice mold separate but attached to a structural base. The structural base includes integral elements such as a water fill cup, stripper, and mounting configuration. The integral nature of the stripper, combined with its “living hinge” feature, allows for an improved method and apparatus for fixing the ice tray in place. The combination provides an icemaker having improved thermal properties, as well as improved manufacturing efficiencies. Other improvements include an improved control system, as well as other cost-saving features.

Abstract: Refrigeration units such as walk-in coolers and freezers, particularly interlocking insulative panels used in construction of such units. The individual insulative panels are characterized by a densified urethane perimeter and a core of low density insulating urethane abutting the perimeter and held in place by a thin outer skin. The densified urethane perimeters of the panels have a tongue-in-groove configuration, as well as a cam locking means, securing abutting panels together.

Abstract: An ice piece maker has a long tray (100) with an arcuately shaped inner surface divided into full crescent shaped cavities (122) arranged sideby-side along the tray length. A bidirectional rotatable shaft (106) is positioned with its axis coincident with the axis of the inner surface of the tray. Leading and lagging rows of ejector elements (114), (116) are in separate planes with said leading ejector elements (114) extending downwardly into the center of the cavities, herein defined as the 0.degree. position of rotation, and with first ends of the leading ejector elements (114) attached to the shaft and being of a length to leave a space between its second ends and the tray bottom so that an ice bridge (152) can form between the leading and lagging ice pieces. A control controls the shaft rotation to a clockwise direction for X.degree.

Abstract: A supporting assembly for abutting insulating ceiling or wall panels which are camlocked together, comprising a structural support, a flanged spacer member secured between the structural support and the panels, and a thread rod extending longitudinally through the structural support, spacer member and panels, in threaded engagement with a tapped opening in the camlock. The disclosed assembly eliminates complete penetration or through bolting of the panels, preserves the integrity of the basketed panel joints, and allows simple access to the camlocks during panel erection.

Abstract: A half crescent shaped ice piece maker comprising a freezing tray (100) having an inner surface arcuately shaped about a longitudinal radial axis and divided into crescent shaped water fillable cavities (112) in which the ice pieces are formed, and an ejector assembly (102) for rotatively moving the ice pieces out of the cavities (122) comprising a rotatable shaft (106) supported in bearings with its axis coincident with the radial axis, and with ejector assembly (102) further comprising a row of primary flexible, spring-like ejector elements (114) lying in a common plane and each secured at a first end to the shaft (106) and having its second end extend into one of the crescent shaped cavities (122) to divide the cavity (122) into rotatively leading and lagging partial crescent shaped cavities while water is injected and frozen therein and before the ejector assembly (102) is rotated to form leading and lagging rows of partial crescent ice pieces with ice bridges (152) around the edges of the ejector element

Abstract: An ice maker comprising an elongated freezing tray (100) having arcuately shaped cross sectional configuration with equal-spaced separators (120) formed therein each in a plane normal to the axis of the elongated freezing tray (100) and comprising a rotatable assembly comprising a first hollow, cylindrical shaft (100) rotatably secured near both ends of the tray (100) substantially coincident with the axis of the tray (100) and having generally flat paddle-shaped ejector elements (114 and 115) formed thereon a second hollow, cylindrical non-rotatable shaft (160) positioned within the first cylindrical shaft (106) and non-rotatably secured at one end to the tray (100) assembly; a heating element (113) positioned within the second, hollow cylindrical shaft (160) comprising a power source (309) for supplying power thereto to heat the heating element (113) and by conduction to heat the first and second hollow, cylindrical shaft 160 and the ejector elements (114 and 115) to release the full crescent shaped ice pie
