    • A traction device for a downhill ski is disclosed. In one embodiment the traction device includes a traction member which is movably interconnected with the downhill ski. At least one biasing member actively biases this traction member toward a position where at least a portion of the traction member will extend beyond the entire lower surface of the downhill ski or an “active” position. However, the traction member can be retained in a non-traction or “inactive” position by a latch. Appropriate movement of the latch allows the biasing member(s) to move the traction member into the desired traction position. The end of a ski pole can be used to activate the latch and initiate movement of the traction member. In one embodiment this traction device is integrated with the structure of the binding. This allows the traction device to be automatically moved to its “active” position whenever a ski boot comes out of the binding, such that the traction device in this instance will act as a ski brake. However, the traction device can be selectively and manually moved to either its active or inactive position while the ski boot is disposed in the binding.
    • 公开了一种用于下坡滑雪板的牵引装置。 在一个实施例中,牵引装置包括牵引构件,该牵引构件与下坡滑雪板可移动地相互连接。 至少一个偏置构件主动地将该牵引构件偏压到至少一部分牵引构件将延伸超过下坡滑雪板的整个下表面或“主动”位置的位置。 然而,牵引构件可以通过闩锁保持在非牵引或“无效”位置。 闩锁的适当运动允许偏置构件将牵引构件移动到期望的牵引位置。 滑雪杖的末端可用于启动闩锁并启动牵引构件的移动。 在一个实施例中,该牵引装置与装订结构相结合。 这使得每当滑雪靴从装订中出来时,牵引装置就可以自动地移动到其“主动”位置,使得在这种情况下牵引装置将用作滑雪制动器。 然而,牵引装置可以选择性地和手动地移动到其活动或非活动位置,同时将滑雪靴设置在装订中。

    • A traction device for a downhill ski is disclosed. In one embodiment the traction device includes a traction member which is pivotally interconnected with the downhill ski. At least one biasing member actively biases this traction member toward a position where at least a portion of the traction member will extend beyond the entire lower surface of the downhill ski. However, the traction member can be retained in a non-traction position by a latch. Appropriate movement of the latch allows the biasing member(s) to pivot the traction member into the desired traction position. The end of a ski pole can be used to activate the latch and initiate movement of the traction member.

    • A device and method for sensing a change in differential pressure within a fluid flow is disclosed. In one embodiment, a differential pressure is induced in a flow of fluid through a conduit between first and second axially spaced locations. One side of a diaphragm, piston, or other differential pressure movably responsive member in a differential pressure housing is exposed to the pressure of the flow at the first location, while its opposite side is exposed to the the pressure of the flow at the second location. A extension or the like engages the diaphragm on its high pressure side and passes out through a wall of the differential pressure housing where it is mechanically interconnected with a switch, which in turn is operatively interconnected with a valve in the conduit. Sufficient movement of the diaphragm due to certain change in the differential pressure between the two sides of the diaphragm will physically move the extension which is engaged therewith, which in turn will physically move the switch to a position where a signal is provided to valve to adjust the flow characteristics through the conduit. These movements may be used to identify an underflow condition where the flow rate between the first and second locations is less than a desired flow rate, and/or to identify an overflow condition where the flow rate between the two locations is more than desired.
    • 公开了一种用于感测流体流中的压差变化的装置和方法。 在一个实施例中,在第一和第二轴向间隔开的位置之间的导管中的流体流中产生压差。 隔膜,活塞或其他差压可移动构件在差压壳体中的一侧暴露于第一位置处的流动的压力,而其相对侧暴露于第二位置处的流动的压力 。 延伸部或类似物在其高压侧接合隔膜,并通过差压壳体的壁传出,其中与开关机械地互连,开关又与导管中的阀可操作地互连。 由于隔膜两侧之间的差压的一定变化,隔膜的足够的运动将物理地移动与其接合的延伸部分,而后者又会将开关物理地移动到向阀门提供信号的位置 通过导管的流动特性。 这些运动可用于识别第一和第二位置之间的流量小于期望流量的下溢条件,和/或识别两个位置之间的流量比期望的溢流状态。
