Abstract: An ergonomically designed ambulatory walking device comprised of a bicycle seat supported by an offset seat post that can be used for both right and left injuries. Different handlebar configurations can move the user's hands any number of different positions laterally to the right or left, higher and lower in relationship to the seat and closer and farther from the pelvis. Different frame sizes and height and seat to hand spread make it possible to fine tune a person's balance by selecting standardized parts. The dispensing method allows for verification of doctor's orders and the procedure for selecting parts by a trained individual allows for proper body positioning of the user. The new and simplified frame design, along with its various components and stabilizers, help persons needing more assistance.

Abstract: A planar seat support of generally V-shaped configuration is pivoted at an apex end to a side of an upstanding support post and includes a narrow width handle section to the front and above a planar seat, which is pivotably mounted to the upper edge of an opposite side seat support section of the seat support. The seat is mounted for limited pivoting with respect to the seat support to facilitate strapping of the walker to the thigh and leg of an afflicted limb of the user with the user in sitting position. A second handle section is integral with the post and extends upwardly therefrom to the side of the seat support, and the first and second handle sections terminate in oppositely directed tubular handles. Grasping of the handle carried by the support post after strapping of the walker to the user's thigh and leg permits the user to easily raise himself to an upright standing position while remaining seated on the seat.

Abstract: A system for applying a foam insulation material which automatically compensates for changes in temperature and flow rates so that an optimum blending of materials can be maintained to provide for the production of high quality insulation.

Abstract: A viewing device for use in conjunction with a level of the type having a see through bubble housing comprising two opposed windows and a bubble chamber situated therebetween. The device includes a base containing a luminescent panel that is arranged to seat in contact against one of the bubble housing windows whereby the panel illuminates the bubble chamber, a post perpendicularly secured to the base and extending upwardly beyond the other bubble housing window and a light shield slidably mounted upon the post and being arranged to seat in locking engagement against the other bubble window, the light shield containing a viewing aperture through which the bubble chamber can be seen and a mirror adjustably supported in the shield to permit off axis reading of the bubble.
