Abstract: A method and apparatus are provided for presenting leasing arrangements for a plurality of rental spaces. The method includes the steps of providing a graphical user interface that depicts the plurality of rental spaces within a two-dimensional layout on a display of the graphical user interface, where a relative size and relative location of each rental space on the display is proportional to a relative physical size and relative location of the actual rental spaces and associating a menu with at least some of the rental spaces on the display where the menu provides additional information regarding the rental space, building, rental space user prospects and associated documents.

Abstract: An arm supporting pillow in sling apparatus, comprising in combination a flexible sling, with a first strap having connection to the sling to be supported by a user, an insert pillow received in the sling, to be retrievable from the sling, the sling and pillow dimensioned to receive a user's forearm alongside the pillow, in the sling.

Abstract: A finger and hand brace, the combination comprising a longitudinally elongated brace body, adapted to be applied lengthwise to the wrist and finger region of the hand; multiple flexible flaps carried by the body to be spaced lengthwise thereof and to extend from the body; separate flaps configured to be wrapped about at least two of the following: hand, wrist, a finger or fingers; and retention means on the brace to retain the flaps in wrapped condition; and two generally longitudinally elongated stiffeners carried by the body, the stiffeners having undulating extent or extents, to readily conform to wrist and finger contour with the fingers extended in natural condition.

Abstract: A finger and hand brace, the combination comprising a longitudinally elongated brace body, adapted to be applied lengthwise to the wrist and finger region of the hand; multiple flexible flaps carried by the body to be spaced lengthwise thereof and to extend from the body; separate flaps configured to be wrapped about at least two of the following: hand, wrist, a finger or fingers; and retention means on the brace to retain the flaps in wrapped condition. Elongated, adjustably bendable inserts may be employed to extend in spaced relation in the body, and a thumb hole may be provided in the body, between the inserts.

Abstract: An arm supporting pillow in sling apparatus, comprising in combination a flexible sling, with a strap to be supported by a user's shoulder area, an insert pillow received in the sling, to be retrievable from the sling, the sling and pillow dimensioned to receive a user's forearm alongside the pillow, in the sling.

Abstract: A positioner to control the position of a finger or thumb of the hand, comprising an elongated, flexible holder configured to extend along the upper side of the user's finger or thumb; a retainer carried by the holder to retain the tip of the user's finger or thumb, the holder adapted to be anchored, remotely from the retainer, endwise thereof; the holder configured to flex, thereby allowing bending of the finger or thumb, producing tensioning of the holder that resists such bending.

Abstract: An arm brace comprising an elongated relatively stiff support configured for application adjacent the inner side of the arm and for nesting adjacent the obtusely angled inner side zone of the partly bent arm opposite the elbow; retainer straps carried by the support near opposite ends thereof, to be independently tightened about the arm at retention locations spaced from a shallow angle shaped mid-section of the support, whereby the user's arm is maintained in shallowly bent condition by the brace.

Abstract: A thumb and wrist brace comprising, in combination, the brace having multiple elongated stiffeners with extents generally alongside the thumb, and strap means carried to wrap relative to the thumb and proximate the stiffener extents, whereby the main extent of the thumb is substantially immobilized by the stiffeners and strap means, at least one stiffener extending to a wrist zone of the brace.

Abstract: In ankle brace apparatus, the combination comprises a foot and ankle holder having a foot portion, and having an upper ankle portion with opposite first and second sides; support strap structure operatively connected to a holder to extend under foot portion and then to extend generally upwardly and rearwardly for retention to those opposite sides at retention zones; and retention flaps connected to the holder and extending forwardly to overlap support strap structure at retention zones, the retention flaps spaced apart to provide freely adjustable and conforming cushioning at the rear of the holder.

Abstract: Compositions useful in decomposition molding procedures such as destructive foam casting or ceramic or metallic powder sintering are provided by blends of polymers having greater than 50 weight percent propylene carbonate units and polymers having greater than 50 weight percent methyl methacrylate units. Such blends exhibit an unexpectedly even decomposition profile over the range of temperatures at which their constituent polymers each decompose relatively rapidly. The controlled decomposition rate reduces problems in destructive foam casting and ceramic or metallic powder molding caused by sudden release of gases by the foam pattern or the polymer binder. Preferred blends contain 35 to 65 weight percent poly(methyl methacrylate) and 65 to 35 weight percent poly(propylene carbonate), and very even decomposition behavior is exhibited by blends of 35 to 45 weight percent poly(methyl methacrylate) and 65 to 55 weight percent poly(propylene carbonate).

Abstract: The present invention relates to a binder and a method for making and shaping a green body of ceramic powder and subsequently producing a formed ceramic body. The method of the present invention comprises admixing a ceramic powder with a binder comprising a polyalkylene carbonate to form a ceramic-binder mixture. The binder of the present invention comprises a polyalkylene carbonate, preferably polyethylene carbonate or polypropylene carbonate.

Abstract: The present invention is a novel class of block copolymers and a process of making the same. An alkylene oxide is reacted with CO.sub.2 in an organic solvent in the presence of an organometallic catalyst to form a polyalkylene carbonate. A second alkylene oxide is subsequently added without the addition of catalyst. The resulting product is a block copolymer comprising distinct, covalently linked, alkylene carbonate blocks.

Abstract: Metal castings having reduced residual carbon ash and surface flaws are produced by an evaporative pattern casting process, in which an organic foam pattern is vaporized upon contact with a molten metal leaving a metal replica of the pattern. The organic foam used in this process comprises a polymer formed by polymerizing CO.sub.2 with one or more oxirane compounds.
