A method of analyzing a finite element model of an airfoil assembly. The airfoil assembly comprises a main airfoil element and a plurality of control surfaces. The method comprises: generating a loads interface model of the airfoil assembly comprising: data which defines the spatial positions of a set of nodes, and data which associates each node with either the main element or one of the control surfaces. Load data is generated which defines loads acting on the nodes of the loads interface model, and mapped onto a finite element model to produce a loaded finite element model. A stress analysis is then performed on the loaded finite element model, and the finite element model can be refined as a result of the stress analysis.

The present invention provides an improved head restraint that can be used in conjunction with conventional cattle chutes that are equipped with head gates. It provides the advantages of being humane by causing little or no discomfort to the cattle being restrained. Cattle being treated also tends to remain calm while being restrained utilizing the device of this invention. It offers much easier and faster means for providing care to positions on the head of the animal. Its implementation can accordingly lead to reduction in human labor requirements associated with treating a herd of cattle and generally leads to savings in medication by virtue of being able to more accurately apply eye drops, ointments, or powdered medications to the eyes of a cow having a very stabilized head as compared to loss of medication when dealing with a struggling animal that is jerking its head around during the procedure. Its use greatly reduces the risk of injury to the animal and the person administering the treatment to the animal. Head restraints of this invention offer the advantage of being capable of being affixed to existing chutes of differing sizes. This is because the improved head restraints of this invention are expandable to fit directly onto head gates of differing designs and sizes. The present invention more specifically discloses a head restraint for utilization in conjunction with a cattle chute, said head restraint being comprised of a lower neck restraint, an upper neck restraint which is mounted to the lower neck restraint, a nose restraint which is mounted to the lower neck restraint, a first cattle chute attachment adaptor, and a second cattle chute attachment adaptor, wherein the lower neck restraint is comprised of an upper tubular member and a lower tubular member, wherein the first cattle chute attachment adaptor and the second cattle chute attachment adaptor are attached to the lower neck restraint through tubular members that extend into the upper tubular member and the lower tubular member, wherein the upper neck restraint is adapted to swivel into a position forming an inverted U-shape over the top of the lower neck restraint, and wherein the nose restraint is adapted to swivel by horizontal motion into a position forming a closed U-shape with the lower neck restraint.

The subject invention described herein is directed to an improved fluid powered system for dispensing a selectively variable proportion of additives into a primary fluid supply line such as is commonly encountered in the firefight industry where it is desirable to proportion foam concentrates into a water line. The subject invention features a water driven motor that is integral to a variable displacement additive pump. A proportioning adjustment allows the solution % to be adjusted. Once set, the additive percent varies in direct proportion to the water flow rate in order to maintain a nearly constant solution percentage over a broad flow range.
