  • Patent number: 7611275
    Abstract: A portable assembly for mixing water with cement powder and dispensing produced paste into a predetermined area, comprising a removable mixer assembly including an elongated mixing shaft, means for generating and transmitting a rotational motion to the mixer assembly, an uprightly supported mixing body having a mixing chamber including an upper opening and inner space for the water and dry cement to be mixed and homogenized inside thereof and aided by the mixing shaft. Also including a discharging mechanism having fixed and movable grip members to be manually actuated, than in turn actuate a spring assembly and releases a closure member to permit the mixed homogenized paste to flow out of the mixing chamber. The discharging mechanism further includes a guiding plate assembly to prevent the over spillage of the produced cement paste and guide the discharging flow out directly into the selected area.

  • Patent number: 6199552
    Abstract: An apparatus for facilitating sexual relations with minimum movement by suspending a partner at controllable parallel and spaced apart relationship with respect to another partner resting on a flat cushioned surface. A cable assembly with several cables are cooperatively tied at one end to the suspended platform supporting one of the partners and the other end wound by spool members included in a motorized spool assembly. The activation of the motorized spool assembly brings the platform up and down. A reciprocating movement is also applied to the suspended platform, and all of these movements are controlled by a circuit that includes hard-wired or remote inputs.
