Abstract: A ski binding reduces a likelihood of injury to the anterior cruciate ligament (ACL) and the tibia is accomplished by absorption in the binding to limit loads transmitted through the boot-binding interface. Release based on an injury threshold includes a binding response tower attached to the ski and adapted for selective engagement with the ski, such that the binding response tower permits biased vertical and lateral horizontal displacement, prior to a release threshold. The binding is in communication with the boot heel and is adapted for slideable engagement in response to vertical and lateral forces exerted from the boot heel. The binding response tower adapted to disengage, or release upon reaching at least one a predetermined lateral displacement or a predetermined vertical displacement, such as when the boot heel is forced sufficiently sideways or upwards due to skier movement that would tend to cause an ACL injury.

Abstract: A spring support of the constant spring force type suitable for supporting pipes in installations where the pipes are liable to move laterally while in use, as for example in the case of pipes through which steam is conveyed, is arranged so that the pipe or other load which the support has to carry in use can be attached to a pivoted lever of the support at various positions at different distances from the pivot. The load is attached through load connecting means to a carrier which is variably positioned on the lever. By adjusting the position of the carrier the turning moment produced on the lever by any one of a range of loads can be arranged to be equal and opposite to the turning moment produced by the spring force which acts on the lever. The facility for adjustment has the manufacturing advantage that a standard form of lever can be produced for supporting a range of loads.
