摘要： An electrostatic precipitator type filter is combined with replaceable, polarizable trapping media. In one aspect of the invention, the media is fitted between polarizing plates. In another aspect, the media is coated in sections to form a conductive surface which serve as the equivalent to the charged plates of the precipitator. These electrodes may be alternately displaced to provide a ready means to effect electrical connections.

摘要： A connector device for connecting and towing a wheeled cart to and by a bicycle, having an elongated shaft including an aligned bolt with a head and having a front longitudinally aligned socket. A pivot ball, secured to the towing bicycle, and adapted to be removably held in the socket of the device. A slidable sleeve on the shaft over the socket extension of the device for so removably holding the ball in the socket in one slidable position thereof on the shaft. A removable spring sleeve holding clamp on the shaft. A rotatable slidable collar extending over the shaft extension. A coil extension spring on the bolt portion of the shaft, between the bolt head and said collar, with said slidable rotatable collar being adapted to have the towed cart tongue secured thereto. Said connecting device permitting a rotation of either the bolt or said collar of the device, with relation to each other upon bicycle torque pulling of the towed cart, on device connection use.

摘要： A business card holder includes a support for containing a number of business cards permitting vertical extraction of one card from the set by grasping the card along its narrower upper edge. The lower surface of the support is bevelled so as to cause the set of cards to be presented at the upper end of the support at differing heights for ease of extraction. The upper edge of at least one wall containing the cards is lower than the top edge of all of the cards in the set, providing an edge that will permit the uppermost card to be bent slightly outward over this top edge for extraction. The vertical height of the card support when positioned within a pocket may be established by providing a downwardly extending leg that will rest against the bottom of the pocket.
摘要翻译：名片夹包括一个支持，用于容纳许多名片，允许通过沿着较窄的上边缘抓住卡从集合中垂直提取一张卡。支撑件的下表面是斜面的，以便使得该组卡在不同的高度处呈现在支撑件的上端，以便于提取。包含卡的至少一个壁的上边缘低于该组中所有卡的顶部边缘，提供允许最上面的卡在该顶部边缘上略微向外弯曲以提取的边缘。当卡定位在口袋内时，卡片支撑件的垂直高度可以通过提供一个向下延伸的腿而建立，该腿可以靠在口袋的底部。

摘要： A needle guard (1) based upon a canting plate (6) becomes lockingly engaged with the needle (2) shaft both upon retraction of the needle tip within the guard (1), and upon any attempt to cause the needle tip to reemerge from the guard (1). The plate (6) is positioned to rotate into locking engagement with the shaft of the needle (2) both when an attempt is made to further withdraw the needle from the needle guard (1) and when an attempt is made to cause the needle tip to reemerge from the needle guard (1).
