  • Patent number: 5338116
    Abstract: A device for guiding a submersible mixer 1 through a receptacle comprises two cable sections 7 having upper ends fixed to the receptacle and lower ends received by supporting members 10 mounted to the bottom surface of the receptacle. A guide slide 4, alternatively attached to the receptacle and the submersible mixer by two connecting elements 13, has two tubular posts 60, 61 that are slidably coupled to the cable sections 7. After lowering the submersible mixer 1 onto the guide slide 4, the connecting elements 13 are detached from the receptacle and attached to the submersible mixer, one after the other, so that the guide slide 4 is firmly anchored to the receptacle until the submersible mixer 1 is secured to the guide slide 4. The guide slide 4, with the submersible mixer 1 secured thereon, is then lowered through the receptacle and onto the two supporting members 10 so that the submersible mixer 1 can conduct operations in the receptacle.
