Abstract: A downhole motor universal joint assembly includes a female coupler which receives a male end of a drive shaft. The female coupler has a retainer that prevents separation of the male end and the female coupler. The retainer has a rearward extending skirt with flow passages to prevent solid material from accumulating in an exposed space between the female coupler and the male coupler. Also to prevent solid material from accumulating in this space, a shoulder formed on the male coupler diverts the flow of well fluid towards the outside of the joint. Thrust loads are transmitted between the male coupler and the female coupler by a thrust ball positioned between the male coupler and the female coupler. Torque loads are transmitted between the male coupler and the female coupler by a plurality of balls positioned in annularly spaced concave pockets on the exterior surface of the male coupler.

Abstract: An antler removal and collection device includes an antlered animal attractant holder adapted and constructed to hold an antlered animal attractant. The device also includes a flexible antler removal assembly mounted in proximity with the antlered animal attractant holder, the flexible antler removal assembly including at least one elastic antler removal element. The at least one elastic antler removal element is adapted and constructed to exert sufficient force to remove antlers that are ready to be shed by animals coming into proximity with the antlered animal attractant, but insufficient force to trap the antlered animal in the flexible antler removal assembly. The flexible antler removal assembly can include at least one frame assembly upon which the at least one elastic antler removal element is mounted. In an embodiment, the at least one frame assembly is provided as a pair of frame assemblies and a corresponding pair of elastic antler removal elements.
