  • Patent number: 11304489
    Abstract: A salon chemical dispensing assembly for storing a selectively dispensing a fluid salon treatment includes a bottle for storing a fluid salon treatment. A pumping unit is removably coupled to the bottle to urge the fluid salon treatment outwardly from the bottle when the pumping unit is turned on. A dispensing nozzle is removably coupled to the pumping unit and the fluid salon treatment in the bottle is pumped into the dispensing nozzle thereby facilitating the dispensing nozzle to dispense the fluid salon treatment. A pick housing is movably coupled to the bottle and a pick is slidably positioned in the pick housing. The pick is positionable in a stored position having the pick being retracted into the pick housing. The pick is positionable in a deployed position having the pick extending outwardly from the pick housing.

  • Patent number: 10472053
    Abstract: A retractable wheel assembly includes arm assemblies, wheels, retraction arms, guide blocks, and a threaded shaft. The arm assemblies are hingedly attached to a lower frame of a utility vehicle. Each arm assembly comprises a first arm, a second arm, and a third arm hingedly linked therebetween. Each wheel is connected to the third arm of each arm assembly. The retraction arm is connected to the second arm, and a threaded shaft. The threaded shaft is configured to be actuated rearwardly where the retraction arm is rearwardly pulled helped by a guide block to convert the longitudinal movement to vertical movement, causing the second arm to fold the arm assembly inwardly when the trailer is positioned at rest. Then the threaded shaft is configured to be actuated forwardly where the retraction arm is pushed forward and helped by a guide block to convert the longitudinal movement to vertical movement causing the second arm to unfold the arm assembly outwardly to deploy the wheels for motion.

  • Patent number: 10179434
    Abstract: Molding assemblies and molding processes are disclosed. The molding assemblies are for producing a product and include a first subassembly and a second subassembly for the producing of the product. The first subassembly includes a cavity insert arrangement corresponding with the design of the product, a movable insert abutting the cavity insert arrangement, and rail members securing the movable insert with interlocking features at a specific location, the specific location being one of multiple movable insert positions. The molding process includes molding a first product with the movable insert and the additional movable insert being positioned at a first movable insert portion, removing the subassembly from the second subassembly, re-positioning the movable insert and the additional movable insert to a second movable insert position, and molding a second product with the movable insert and the additional movable insert being positioned at the second movable insert portion.

  • Patent number: 9822158
    Abstract: A method for crystallizing insulin or insulin analogs under alkaline conditions and purifying the insulin or insulin analog crystals by filtering through a filter and drying the insulin or insulin analog crystals captured on the filter to produce crystalline insulin or insulin analog crystal compositions is described. In particular aspects, the method may be used to crystalize insulin glargine.
