Abstract: The present disclosure relates to a workpiece carrier for transporting and/or storing components of a drug delivery device. The workpiece carrier includes a body including a planar-shaped bottom area. The planar-shaped bottom area includes an upper side and a bottom side opposite to the upper side. The bottom area includes a number of longitudinally extending hollow protuberances protruding from the bottom side and forming longitudinally extending cavities in the upper side. A longitudinal end of at least one of the protuberances or cavities faces away from the bottom side comprises an aperture.

Abstract: A dynamic helical mixer and a mixing head apparatus using that mixer are disclosed. Highly efficient mixing of two or more component reactive systems that have drastically different viscosities and ratios can be achieved because the mixer provides high shear in a mixing apparatus with a very small hold-up volume in the mixing head. The mixing head utilizes a hydraulic motor to transfer power to the dynamic helical mixer.

Abstract: A heated pump assembly having a proportioner pump that pumps components in a preselected ratio from their storage drums. The first component is drawn from its storage drum and divided into two portions, one portion going to a first supply tube and one portion going to third supply tube. The first portion travels from the first supply tube to a first primary heater and the second portion travels through the third supply tube to a second primary heater. The two portions of the first component are combined and sent to a final heater. After traveling through the final heater, the heated first component is sent to the spray applicator, preferably through a heated hose. The second component is sent by the assembly as the second input to the spray applicator.
