  • Publication number: 20200301085
    Abstract: An fiber-optic connector assembly includes a fiber optic ferrule and a connector, which engage an optical transceiver component. The fiber optic ferrule engages a mating plane of a lens array in the optical transceiver component and floats within the connector. The engagement of the assembly and the optical transceiver component may be removable rather than fixed. The fiber optic ferrule also engages a mechanical interface to account for three degrees of freedom, while the engagement of the mating surfaces account for another three degrees of freedom.

  • Patent number: 10781117
    Abstract: The present invention relates to a method of dewatering an aqueous mineral suspension comprising introducing into the suspension a flocculating system comprising a mixture of polyethylene glycol and polyethylene oxide polymers, in particular a mixture of one or more low molecular mass polyethylene glycol with one or more high molecular mass polyethylene oxide. Said mixture of polyethylene glycol and polyethylene oxide polymers is useful for the treatment of suspensions of particulate material, especially waste mineral slurries. The invention is particularly suitable for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.

  • Publication number: 20200285001
    Abstract: A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.

  • Publication number: 20200241214
    Abstract: A fiber optic connector assembly is mated with a bracket on a printed circuit board at one end and inserted into a backplane adapter that is adjacent a backplane. In particular a spring push in slidingly attached to the bracket and also to the housing of the fiber optic connector assembly. The housing of the fiber optic connector assembly insertable into the backplane adapter using passive alignment features. A fiber optic ferrule in the fiber optic connector assembly is biased in a forward direction by a spring in the spring push. At the same time the spring allows for movement of the spring push within the housing to allow for movement of the printed circuit board relative to the backplane adapter.

  • Publication number: 20190162913
    Abstract: A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.
