A mounting structure including a clip portion embraces the nose of a computer keyboard housing with tabs that snap into the space between housing and keys for securing a toggle assembly over the cursor keys in an inverted 'T' array cursor pad. A toggle assembly with radiating arms is held over the 'DOWN' key with fingers resting on or in close proximity to all four cursor keys and joined through an elastomeric toroid to the mounting structure for resilient articulable motion in response to manual manipulation of a toggle lever to thereby provide joystick operation of the cursor via the cursor keys.

Cursor key actuating assembly

A solar collector unit adapted to be installed between the studs or rafters of a building, the unit comprising one or more strips of thin metal welded to three parallel tubes, the intermediate tube having a bore larger than the bores of the two other tubes and the tubes being connected to headers so that fluid flowing in the two tubes flows through the intermediate tube and so that connections of a fluid source to the tubes is made at one end of the unit. The headers carry brackets by which the unit may be secured to, and supported by, the studs or rafters. The sunlight receiving side of the unit is covered by glazing secured to the building and the opposite side is covered by insulation.

Methods for manufacturing heat exchange panels each comprising metal tubes of finite length welded to a metal sheet except at the end portions of the tubes which are secured to headers in fluid-tight relation thereto, in which methods the metal sheet, having end edges and side edges, is formed into a hollow cylinder with the end edges adjacent each other and metal tubing is welded to the cylinder in a spiral path. Welding is interrupted adjacent the end edges and the tubing is cut above the end edges to provide tubes welded to the cylinder except at end portions of the tubes. The end portions of the tubes, after the cylinder-tube combination is formed to the desired shape, e.g., flat, are secured to the headers. If tubes parallel to the side edges of the sheet are desired, the hollow cylinder is formed with adjacent portions of the side edges in axially offset relation prior to welding the tubing to the cylinder.
