Abstract: A directional drilling mechanism is disclosed. The mechanism is also an impact drill.

Abstract: Apparatus and methods for applying heated sealants, such as molten polymeric material, to surfaces such as for filling cracks in pavement surfaces. Aspects of the invention include block cutting assembly, heated dispensing hose, and crack filling applicator head. By way of example, the block cutting assembly comprises a ram device for driving sealant blocks against a heated cutting member which severs the blocks to speed liquefaction within the heated sealant chamber. An associated enclosure incorporates a loading door preferably configured for operation in response to the position of the ram device. The heated dispensing hose may comprise a heating element running through the interior of the hose to heat sealants as they pass through the hose. The crack filling applicator head comprises a dispensing tube upon which a sealing chamber is coupled for retaining a quantity of liquid sealant proximal to the pavement surface being filled.

Abstract: A method for prevention and treatment of multiple sclerosis and other demyelinating conditions is disclosed. The method includes two subsequent phases. In each phase, a patient orally administers daily a regimen which includes a specific combination of amino acids, fatty acids, vitamins and minerals. The particular regimens provide vital nutrients necessary to re-build fatty acids that may have been lost or reduced in the myelin sheathing and other locations of brain, therefore decrease one's susceptibility to multiple sclerosis and prevent reoccurrence of the disease.
