  • Patent number: 10633316
    Abstract: The present disclosure is directed towards methods of converting glycerol to an allyl compound, involving deoxydehydrating glycerol with formic acid and heat to form allyl alcohol; and esterifying the allyl alcohol with formic acid and/or phthalic anhydride and heat to form allyl formate and diallyl phthalate. In some instances, the heat is generated by a microwave. In further instances, the methods involve polymerizing the allyl alcohol, allyl formate and/or diallyl phthalate to form poly(allyl alcohol) or poly(allyl formate) or poly (diallyl phthalate). In some instances, the allyl polymers were used for the consolidation of oil sands tailings.

  • Publication number: 20170210641
    Abstract: Methods of using modified keratin to remove trace metals and/or napthenic acids from a waste water stream are described. The waste water stream may be mature or fine fluid tailings from oil sands operations, and the methods may include the removal of trace metals, naphthenic acids with simultaneous consolidation of the tailings. The keratin may be modified to unfold the keratin, disrupt disulphide bonding, add functional groups, and/or maintain or stabilize the unfolded configuration.

  • Patent number: 4119028
    Abstract: A refuse compactor having a receptacle for holding the refuse during compacting in which the container is distortable and includes a pressure deformable section on at least one side normally bulging out of alignment with the adjacent area of the receptacle under conditions of substantially no pressure and a pressure member on the compactor for retaining said section deformed in substantial alignment with the side of the container during the compacting. This pressure deformable section facilitates removal of the filled container after compressing the refuse from the compactor and also facilitates removal of the compacted refuse from the container.

  • Patent number: 4084497
    Abstract: A refuse compactor structure wherein refuse collected in a flexible, outwardly opening container is compacted by downward movement of a ram thereagainst. The container is laterally supported during the compacting operation by an arrangement of walls substantially fully surrounding the container. The wall arrangement is constricted as a result of a preselected movement of the compacting ram to provide the desired lateral support during the compacting operation. The walls are retracted from the container as an incident of the ram being returned to a retracted position. The container is supported on a movable carrier which may be withdrawn through a front opening of an outer cabinet of the structure for introducing additional refuse into the container or for removing the container as for disposition of the compacted refuse. The carrier supports a door for selectively closing the front opening of the cabinet.

  • Patent number: 4016608
    Abstract: Shaped springs are fitted to a flange of a modular package such as a sink-disposer unit inserted through an aperture in a surface. One camming surface moves each spring out of the way during insertion of the package into the aperture and a second camming surface sprung outwardly against the wall of the aperture to obstruct removal of the package as insertion is completed. The spring may then be selectively tensioned by a threaded nut.
