Curable silicone compositions comprising an aryl group-containing organopolysiloxane gum having a consistency of 200 to 900 as a rheological modifier are provided. Use of the curable silicone compositions comprising an aryl group-containing organopolysiloxane gum having a consistency of 200 to 900 in methods for additive manufacturing a three-dimensional silicone elastomer article are further provided.

Use of aryl group containing organopolysiloxane gums as additives to increase rheological behavior

A reversible, portable leg exercising apparatus includes an inclined guideway supported on a frame. The guideway has upper and lower ends. A pedal is mounted for relative sliding movement along the guideway. A first reversing roller is provided at the upper end of the guideway and a second reversing roller is provided at the lower end. An elastic cord provides resistance to movement of the pedal. The elastic cord is selectively connectable in one of two positions. In a seated exercise position a first end of the cord is held by the pedal, an intermediate portion extends over the first reversing roller and a second end of the cord is held by the second reversing roller. In a reclined exercise position the first end of the cord is held by the first reversing roller, the intermediate portion of the cord extends over the second reversing roller and the second end of the cord is held by the pedal.

Portable and reversible leg exercising apparatus

A portable leg exercising apparatus especially adapted for lower back rehabilitation is provided, having an adjustable, V-shaped frame assembly constructed from lightweight tubular material, and oriented so that a base forming one side of the V lies adjacent to the floor. The other side of the V extends upwardly from the vertex at an incline forming spaced guide rails. Adjustable support braces extend between the two sides of the V-shaped frame opposite the vertex. The support braces and cross tube are adjustable to accommodate various angles of inclination of the guide rails. In the extreme lowered position, the frame assembly is substantially flattened to facilitate portability and storage. Independently movable carriages having foot pedals slide along the rails in response to the force applied by the legs of the user. Elastic cords extending between the frame and the carriages serve to provide elastic resistance to the leg motion as the carriages move upwardly along the inclined rails. The foot pedals may be lowered to enhance the portability/storage capability.
