    • A descender (1) for controlling descent of a person down a rope fixed to an anchor point, the descender comprising a rope entry guide (6) and a rope exit, an eccentrically mounted swivellable camlock (4) having a rope braking surface operable to releasably lock the rope in position against the entry guide (6) in response to movement of the rope towards the exit, and means to adjustably unlock the camlock, said unlock means including a swivellable handle (3) drivingly connected to an inner drive cam (8), the inner drive cam having bearing surfaces co-operable with the cam surfaces of an outer drive cam (11) within or on the body of the camlock (4), the arrangement being such that the reaction forces applied to the inner cam (8) via the handle (3) are transmitted to the cam surfaces of the outer cam (11) to thereby provide a mechanical advantage for causing the camlock (4) to open to thereby release the rope and thereafter allow further descent from the anchor point.
    • 一个下降器(1),用于控制一个人固定在固定点上的绳索的下降,下降器包括一个绳索入口引导件(6)和一个绳索出​​口,一个偏心安装的可旋转的凸轮锁(4),其具有绳索制动表面, 响应于绳索朝向出口的移动而将绳索可释放地锁定在适当位置上,并且可调整地解锁凸轮的装置,所述解锁装置包括驱动地连接到内部驱动凸轮的可转动手柄(3) 如图8所示,内部驱动凸轮具有与凸轮锁(4)的主体内或外部驱动凸轮(11)的凸轮表面可配合的支承表面,该布置使得施加到内凸轮 (8)通过手柄(3)传递到外凸轮(11)的凸轮表面,从而提供用于使凸轮锁(4)打开的机械优点,从而释放绳索,然后允许从锚 点。

    • Improvements in a fire escape having a structure of a Helix/Spiral Cylinder shape. It's a building within a building. It provides a quick and safe evacuation for all fire victims, including the A.D.A., the injured and the elderly. Its spiral design can accommodate a large number of floor levels. It eliminates the hazards acquainted with stairs and elevators. It has the capability of removing some of the smoke from the high-rise fire by way of a metal Ducting System. It draws the smoke into the center smoke shaft. The spiral is a two-way traffic pathway, which offers Fire Department personnel and their equipment a method of upward transportation to any floor-level they need for fighting this fire incident. My design can be retrofitted to any existing building.
    • 具有螺旋/螺旋圆柱形结构的消防器具的改进。 这是建筑物内的建筑物。 它为所有的火灾受害者,包括A.D.A.,受伤和老人提供了一个快速安全的撤离。 其螺旋设计可以容纳大量楼层。 它消除了熟悉楼梯和电梯的危险。 它能够通过金属管道系统从高层火灾中清除一些烟雾。 它将烟雾吸入中心烟雾轴。 螺旋线是一个双向交通路径,为消防局人员及其设备提供了一种向上运输方式,用于对付这起火灾事件所需的任何楼层。 我的设计可以改装到任何现有的建筑物。
