  • Patent number: 11813240
    Abstract: A composition includes a microemulsion. The microemulsion includes an aqueous phase, an oil phase, and a surface-active agent. The aqueous phase includes water and at least one polyol. The oil phase includes a therapeutically effective amount of tolnaftate and a carrier including Jojoba oil. The microemulsion includes a disperse phase having a particle size of 50 nm or less. A method for making a composition includes forming a first mixture by combining water and at least one polyol; forming a second mixture by combining Jojoba oil, a surface-active agent, and a therapeutically effective amount of tolnaftate; and combining and mixing the first mixture and the second mixture to form a microemulsion.

  • Publication number: 20220213661
    Abstract: A ground improvement apparatus includes: an irrotational sun gear fixed to an irrotational inner pipe inside a rotatable outer pipe; a planetary gear rotatably supported on a rotatable agitation shaft and configured to rotate while meshing with the sun gear; and an inverse rotation mechanism meshing with the planetary gear and rotating the agitation shaft in an opposite direction of the planetary gear. The agitation shaft is suspended on a connection member attached to the outer pipe so as to rotate in synchronization with a rotation center of the inverse rotation mechanism. A ground where the outer pipe is penetrated and a solidifying material discharged from the agitation shaft are agitated and mixed with each other by agitation blades radially attached to the agitation shaft with a trajectory of distal ends of the agitation blades drawing a substantially polygonal shape by rotation of the agitation shaft.

  • Patent number: 11319687
    Abstract: A ground improvement apparatus includes: an inner shaft arranged inside an outer pipe and including a mechanism for rotating a crank at a rotation speed four times as fast as that of the outer pipe; agitation blades supported by the outer pipe so as to reciprocate in a radial direction of the outer pipe and including discharge outlets; and a slider crank mechanism for converting a rotation movement of the crank to a reciprocating movement of the agitation blades. A ground at a location where the outer pipe is penetrated and a solidifying material discharged from the discharge outlets are agitated and mixed with each other to form an improved body having a substantially rectangular cross section by rotating the agitation blades while advancing and retreating the agitation blades relative to each other via the slider crank mechanism by rotation of the crank.

  • Patent number: 7651301
    Abstract: A method of soil improvement work drills the ground with a drilling head arranged at a lower end of a rotary shaft and sends the rotary shaft into the ground. The method mixes pressurized water with compressed air on the ground, to prepare a fluid mixture, feeds the fluid mixture through a feed path arranged along the rotary shaft into an ejector arranged on the drilling head, and ejects the fluid mixture from the ejector toward the ground to drill. An envelope defined by a front end of the drilling head has a conical shape.

  • Publication number: 20100000790
    Abstract: The present invention provides for pulsed power breaking and drilling apparatuses and methods. The present invention comprises two pulsed power systems coordinated to fire one right after the other. The first pulsed power system, comprising a spiker, may create a high voltage pulse that breaks down the insulative properties of the substrate and may create an arc channel in the substrate. It is designed for high voltage but low energy, at high impedance. The second pulsed power system, comprising a sustainer, is designed to provide high current into the arc, but at low voltage, thus better matching the impedance of the arc and achieving much more efficient energy transfer.
