Abstract: A home basic body exercise device having a clamp for engaging the walls of adjacent rooms above a doorway with a depending frame pivotally connected to the clamp at one end beneath the doorway and having a bar with a rotatable padded cover at the other end. High tension spring means connect the clamp to the frame intermediate its ends. The device is used to exercise all body areas from a basic standing position acting against the resistance of the spring.

Abstract: A mobile barbecue apparatus is disclosed which comprises a firebox having wheels thereon with turnable receptacles for holding items to be cooked mounted above the firebox. The food containing receptacles are adjustable in width to accommodate different sized items such as steaks, chickens, ribs, etc., which are to be cooked. Preferably the top of the apparatus comprises a removable table having legs positioned at the edges which can be rotated into storage position or into table defining position.

Abstract: A solar heating system includes an array of solar collectors and a manifold through which the collectors are supplied with water, this water being derived from a storage tank located below the collectors. The water is circulated through the collectors by a pump, and within the collectors the water is heated, but when the pump is not operating, the water drains from the collectors into the tank so it will not freeze and damage the collectors. Each solar collector includes a housing, a collector panel in the housing and containing a cavity through which water is circulated, supply and drain pipes which extend the full height of the housing behind the panel and are connected through ports with opposite ends of the panel cavity, and a light transmitting material over the housing. The supply and drain pipes of some of the collectors are plugged into corresponding supply and drain fittings on the manifold at bushings which fit into aligned ends of the pipes and fittings.

Abstract: A water-resistant suntan gel comprising an alcoholic solvent, a sunscreen agent, emollients, a selected acid which enhances the binding ability of the gel film to the skin and a gelling agent for the solvent. The composition prevents sun damage to the skin and promotes an even tan. The composition forms a film on the skin, which film is water insoluble yet easily removable.

Abstract: A non-linear lens possesses distortion characteristics which are such that objects along the optical axis of the lens occupy disproportionately large areas of the image cast by the lens, whereas objects near the periphery of the field of view occupy a disproportionately small area of the image. The distortion characteristics approximate the formula H=sin.sup.1/3 .theta. where H is height measured from the optical axis and .theta. is the angle measured from the optical axis. The image cast by the lens falls on the vidicon of a television camera where it is scanned and transmitted to a projector. Since the lens enlarges objects in the vicinity of the optical axis, those objects are transmitted with much greater detail than objects in the peripheral region of the view. The transmitted image is reproduced at a projector and the reproduced image is rectified through another lens having identical distortion characteristics. This lens casts the rectified image on a spherical screen.
