    摘要: A safety mechanism for a lift system, the safety mechanism including a first motion retarder which operates frictionally between a load-carrying platform and a hoistway and a second motion retarder which operates by breaking a frangible element. The two motion retarders may act together so that when the frictionally engaging element is depleted, the frangible elements are then broken. In an embodiment, the frictional element is disengaged to engage the breaking of the frangible elements when the car is a predetermined distance above a floor of the hoistway, thereby ensuring that the load-carrying platform can be stopped prior to a collision with the floor or ceiling of the hoistway.

    摘要: A plunger for a syringe including a head for reciprocating within a chamber of the syringe to thereby deliver a shot of liquid contained within the chamber, the head further including a seal which is impermeable to liquid, but permeable to gas to allow gas to pass the head, but prevent liquid from doing so.
