  • Patent number: 8425732
    Abstract: A method of operating an assembly for recycling a solvent from a contaminated solvent solution including a source for the contaminated solvent solution at a level and a recycling assembly including a reservoir module and a recycler module. The reservoir module includes a reservoir and the recycler module includes a controller and a distillation assembly including a distiller having a conduit and a pressure relief valve. The pressure relief valve includes a tube. The method includes connecting the conduit to the source below the level; connecting the pressure relief valve tube to the source; pumping solvent into the reservoir, distiller and conduit to an operational level; and selecting a duty cycle of the controller to regulate a rest period after the controller operation of a distillation cycle.

  • Publication number: 20090189009
    Abstract: A holder appliance suitable for axially supporting a rolled product is disclosed having a holder and a rigid or semi-rigid root section. The holder includes a body having first and second ends and an engagement surface disposed therebetween contactable with a planar end surface of the rolled product, and a protrusion extending from the engagement surface toward the rolled product, the protrusion being engageable within an opening in the planar end surface. The root section is disposed at the first end and a tab disposed at the second end of the body. The tab extends radially away from the axis of the rolled product and axially away from the engagement surface. The tab has a greatest radial portion displaced from a plane defined by the engagement surface in a direction opposite to a direction in which the protrusion is extended. The tab has a contour that mirrors a user's thumb.
