The sock-donning tripod is adapted for use with stump socks commonly used by amputees. The sock-donning tripod is a free standing structure that is formed with a top plate. The top plate is formed with center cut out and plurality of posts. Each of the plurality of loop of the stump sock are hooked over a post selected from the plurality of posts which holds the stump sock open over the center cut out. The amputation stump can then be placed into the stump sock. The stump sock is then pulled into position using the patient's hand or a dressing stick by using each of the plurality of loops to pull the stump sock into position. The sock-donning tripod comprises a plurality of legs, a top plate, and a brace plate.

Methods are provided for improving production of 3,5-diethyl-1,2-dihydro-1-phenyl-2-propylpyridine (DHP). In one illustrative embodiment, the methods involve controlling the rate of reaction and temperature of the reaction during formation of DHP. In another illustrative embodiment, the methods involve neutralizing the acid catalyst subsequent to DHP formation.

Process for the preparation of 3,5-diethyl-1,2-dihydro-1-phenyl-2-propylpyridine

Processes for preparing a 4-(secondary or tertiary)aminopyridine are provided. The processes comprise reacting a 4-substituted pyridine base having a leaving group as the 4-substituent, with an activating agent so as to form a corresponding 1,4-substituted pyridine; reacting the 1,4-substituted pyridine with a primary or secondary amine to substitute an amino group at the 4-position, and thereby form a corresponding 1-substituted-4-(secondary or tertiary) aminopyridine, wherein the reacting is conducted in a substitution reaction medium essentially free from strong base; and treating the 1-substituted-4-aminopyridine compound to remove the 1-substituent and thereby form a product medium including the 4-(secondary or tertiary) amino-pyridine.

Supernucleophilic 4-substituted-pyridine catalysts, and processes useful for preparing same

Described are preferred processes for producing extrusion-granulated supernucleophilic 4-amino-substituted pyridine catalysts, and granular products obtainable thereform. Also described are preferred activation-substitution-deactivation processes for producing 4-aminopyridine compounds, which involve the use of acrylic acid or acrylamide or analogs thereof for activation, and substitution steps conducted under mild basic conditions in an excess of the amine reagent for 4-substitution. Such processes provide improved reacted masses which are more readily processed to recover the products in pure, heat-stable form. Further, described are processes for preparing 4-substituted-pyridines via pyridine betaines.
