摘要： A secondary air filter assembly that can be attached to the exhaust port of an upright vacuum cleaner is provided. The assembly includes an adapter plate that is adhered, clipped or otherwise affixed to the exhaust port, and a filter carrier that is removably attached to the base. The filter is preferably affixed as a unit to the filter carrier so that the entire filter/carrier unit can be replaced at once. The adapter base can also be used as an attachment for other accessories.
摘要翻译：提供了可附接到立式吸尘器的排气口的二次空气过滤器组件。组件包括粘合，夹紧或以其他方式固定到排气口的适配器板，以及可移除地附接到基座的过滤器载体。过滤器优选作为一个单元固定到过滤器载体上，使得可以一次更换整个过滤器/载体单元。适配器基座也可用作其他附件的附件。

摘要： Electrical instrument gage that has a pointer indicator member mounted on a rotatable shaft extending from the gage and including an electrically energizable light source mounted on and extending along the pointer portion of the indicator member. The light source is preferably an electroluminescent lamination that contains a pair of flex circuit terminal contacts extending from its base end. The light source is adhesively attached to the pointer portion of the indicator member. The base element of the indicator member contains a socket portion with a cylindrical opening configured to provide a friction fit to the axial shaft extending from the gage. The outer cylindrical surface of the socket contains an electrically conductive area and the gage contains an electrical wiper contact that makes continual electrical interconnection with the conductive portion of the socket over its rotational range. This electrical interconnection provides the power for the light source that is attached to the instrument pointer.
摘要翻译：电气仪表具有指示器指示器构件，该指示器构件安装在从量规延伸的可旋转轴上，并且包括安装在指示器构件的指示器部分上并沿着指示器部件延伸的可电激励光源。光源优选是电致发光层压体，其包含从其基端延伸的一对柔性电路端子触头。光源粘附到指示器构件的指示器部分。指示器构件的基座元件包括具有圆柱形开口的插座部分，其被构造成提供与从量具延伸的轴向摩擦配合。插座的外圆柱形表面包含导电区域，并且量规包含电气擦拭器触点，其使得与插座的导电部分在其旋转范围上的连续电互连。该电互连提供了连接到仪器指针的光源的电源。
