    Abstract: An investment casting method involves producing a casting shell by applying a hardenable refractory material to a sacrificial pattern. The casting shell having a plurality of phosphate bonds in the hardenable refractory material, which provide increased structural integrity during casting and improved frangibility during shell removal. The casting shell may also have a plurality of gaseous pockets suspended in the refractory material, which do not degrade the structural integrity during casting and provide improved frangibility during shell removal.

    Abstract: A medical crutch having a number of bends in the frame for redistributing the amount of pressure applied to a user's hand, arm, and axilla. The frame has a first jog outwardly sidewards relative to a user's body and a second jog outwardly forward relative to the user's body. The frame may attach an adjustable handle, forearm rest and underarm support, among other attachments. The frame is adapted to fit all average sizes by adjusting the positions of the attachments.

    Abstract: A solar water heater absorber absorbs the sun's energy on the surface of a twin-walled polycarbonate panel and conducts the heat from the sun through the panel wall into fluid flow through channels of the panel. The panel is an extruded polycarbonate glazing material that consists of two panes connected by longitudinal ribs to form a plurality of water channels that may further include twisted strips providing a helical water flow pattern that increases turbulence within the water channels. The panel is connected to large pipes or headers on the top and bottom ends of the panel that receive the heated fluid from the water channels, allow the heated fluid to exit the panel, and for return water to re-enter the panel in a solar water heating system.
