    • A smoke detection unit has a detection chamber for sampling smoke from a surrounding environment. The detection chamber allows air circulation but is optically opaque. This configuration is typical of photoelectric smoke detectors, for example. A housing defines a window though which air from the environment circulates into and out of the detection chamber. The window's height is approximately the same as the chamber. A cage vane is positioned in the window and is configured as an inverted frustoconical member. An inner edge of the cage vane is spaced away from the chamber. The angled vane, along the other aspects of the unit's configuration, improves sensitivity by increasing smoke circulation through the chamber. This configuration guides the air currents typically created by fires at the ceiling so that the smoke flows easily into the detection chamber.
    • 烟雾检测单元具有用于从周围环境抽取烟雾的检测室。 检测室允许空气循环,但光学不透明。 这种配置是典型的光电式烟雾探测器。 壳体限定窗口,尽管来自环境的空气循环进入和离开检测室。 窗户的高度与房间大致相同。 笼形叶片定位在窗户中并且被配置为倒立的截头圆锥体构件。 笼式叶片的内边缘与腔室间隔开。 沿着设备结构的其他方面,成角度的叶片通过增加通过室的烟气循环来提高灵敏度。 该配置引导通常由天花板上的火灾产生的气流,使得烟雾容易流入检测室。

    • A membrane switch circuit layout and method for producing a membrane switch circuit layout are disclosed. The membrane switch circuit layout may have two or more membrane layers. Each membrane has a top surface and a bottom surface. A conductive circuit trace is printed on the top surface of each membrane. The membrane layers are placed in a stack with each top membrane having thru-holes selectively cut there through. Thus, for example, in a layout having two membrane layers, the first membrane is positioned beneath the second membrane and the second membrane has thru-holes cut there through. Conductive ink may be pressed through the thru-holes to provide electrical connection between the circuit traces printed on the membrane layers. An adhesive may be placed between the membrane layers as either adhesive printed on one of the membrane layers or as an additional layer.
    • 公开了一种用于制造薄膜开关电路布局的薄膜开关电路布局和方法。 膜开关电路布局可以具有两个或更多个膜层。 每个膜具有顶表面和底表面。 导电电路迹线印刷在每个膜的顶表面上。 膜层被放置在堆叠中,每个顶部膜具有通孔选择性地切割。 因此,例如,在具有两个膜层的布局中,第一膜位于第二膜下方,并且第二膜具有通过其穿过的通孔。 导电油墨可以被压穿通孔,以在印刷在膜层上的电路迹线之间提供电连接。 粘合剂可以作为粘合剂印刷在膜层之一上或作为附加层放置在膜层之间。

    • A disposable bedpan (10) is releasably mountable on a reusable or disposable annular support (12). The support has inner and outer walls (38, 40) and a plurality of support projections (50) between the inner and outer walls which engage with the under surface of a peripheral lip (28) of the disposable bedpan. The support (12) supports the disposable bedpan (10) in use and prevents collapsing and the soiled disposable bedpan can be disposed of to reduce the risk of cross-infection. When the support is disposable, e.g. made from paper pulp, this can also be disposed of in the macerator.
    • 一次性便盆(10)可释放地安装在可重复使用或一次性环形支撑件(12)上。 支撑件具有内壁和外壁(38,40)和在内壁和外壁之间的多个支撑突起(50),其与一次性便盆的外周唇缘(28)的下表面接合。 支撑件(12)支撑使用中的一次性便盆(10)并防止塌缩,并且可以处理脏污的一次性便盆,以减少交叉感染的风险。 当支撑物是一次性的时,例如 由纸浆制成,也可以在剥皮机中处理。
