    • A redundant repeater connected between two transmission mediums that can operate in a repeat state where packets are repeated between the mediums, and a standby state where no packets are repeated and where the repeater determines whether packets are being properly repeated between the transmission mediums by another device. If the repeater determines that packets are being independently repeated it remains in the standby state, and will attempt to leave the standby state and return to the repeat state only if it determines that packets on one medium are not being repeated to the second medium. Two repeaters can be redundantly connected across the same transmission mediums with one operating in repeat state and the other in standby. If one repeater fails, the other will begin repeating all received packets. The repeater determines whether packets are being properly repeated by detecting overlapping or non-overlapping packets between its two transmission mediums.
    • 连接在可以在介质之间重复分组的重复状态的操作的两个传输介质之间的冗余中继器和不重复分组的待机状态,以及中继器确定分组在另一设备之间在传输介质之间是否被正确重复的情况 。 如果中继器确定分组被独立地重复,则它保持在待机状态,并且将尝试离开备用状态,并且仅当确定在一个介质上的分组不被重复到第二媒体时才返回到重复状态。 两个中继器可以跨相同的传输介质进行冗余连接,一个操作在重复状态,另一个在待机状态。 如果一个中继器发生故障,另一个中继器将开始重复所有接收到的数据包。 中继器通过检测其两个传输介质之间的重叠或不重叠的分组来确定分组是否被正确地重复。

    • A clamp frame is disclosed for securing a window frame in a building structure opening by hand without using fasteners. The clamp frame comprises a unitary extruded plastic member that defines a cross section having an integrally formed connection element that mates with a complementarily shaped portion of a window frame to connect the clamp frame and the window frame without fasteners along the length of the clamp frame. The cross section includes a clamp element having at least a leg and a lever. The leg and lever are each connected to the connection element by a living hinge and are movable relative to the connection element between an open position and an overlapping locked position, which results in a clamp load holding together the clamp frame and window frame without the use of fasteners. One end of the leg of the clamp element is constantly urged against the building structure by the lever when the clamp element is in the locked position. The clamp frame may be preassembled by hand onto the window frame before shipping to customers.
    • 公开了一种夹紧框架,用于将窗框固定在建筑物结构开口中,而不使用紧固件。 夹紧框架包括整体挤出的塑料构件,其限定具有整体形成的连接元件的横截面,该连接元件与窗框的互补形状部分配合,以将夹紧框架和窗框架沿着夹具框架的长度连接。 横截面包括具有至少一个腿和一个杠杆的夹紧元件。 腿和杠杆各自通过活动铰链连接到连接元件,并且可以在打开位置和重叠的锁定位置之间相对于连接元件移动,这导致夹紧负载将夹具框架和窗框架保持在一起而不使用 的紧固件。 当夹紧元件处于锁定位置时,夹紧元件的腿部的一端经由杠杆被不断地推靠在建筑结构上。 夹具框架可能在运送给客户之前手动预装配到窗框上。

    • A door check for holding a door in an open position is disclosed, which is particularly useful for thin doors. The door check comprises a check body attached to the door and having an opening. The door check pivots with the door about a first axis. A main link is slidable through the door check opening as the door pivots. A second link is pivotably attached to the main link, and pivotably about a second axis with respect to a rigid member. As the check body pivots about the first axis, the second link pivots about the second axis and the main link translates through the opening in the check body. The main link may have an irregular surface so that a large force may be required to move the door back from the open position to a closed position.
    • 公开了用于将门保持在打开位置的门检查,其对于薄门特别有用。 门检查包括附接到门并具有开口的检查体。 门检查与门围绕第一轴枢转。 当门旋转时,主连杆可以通过门检查开口滑动。 第二连杆可枢转地附接到主连杆上,并且相对于刚性构件可绕第二轴线枢转。 当检查体围绕第一轴线枢转时,第二连杆围绕第二轴线枢转,并且主连杆通过检查体中的开口平移。 主链节可以具有不规则的表面,使得可能需要大的力将门从打开位置移动到关闭位置。

    • An apparatus for continuously plating interior surfaces of loose piece electrical terminals is characterized in that loose piece terminals are continuously fed to a continuously rotating mandrel, are held against the mandrel during the plating process by retaining means and are released from the mandrel, the mandrel having a plurality of anode containing nozzles therein, the anodes being mounted for reciprocation into and out of the interior of the terminals that are against the mandrel. A conduit supplies plating solution under pressure through the nozzles and upon the anodes and into the interiors of the terminals in which the anodes are received. The retaining means is an elongated resiliently mounted member which surrounds a portion of a rotating mandrel whereby the loose pieces are held against the mandrel during the plating process wherein the anodes move into the interiors of the terminals, plating solution is injected over the anodes and the anodes are retracted from the terminals, the terminals being released from the mandrel after the anodes have been retracted and the terminals have passed the end of the retaining means.

    • A piano action keyboard for an electronic musical instrument or the like wipes a switch actuator (or other mechanical component of electric signal translation means) across switch contacts on a printed circuit board to generate signals indicative of the position and motionof a key when played. The keyboard provides a highly realistic piano "feel" through an array of paired depressable playing keys and arms. Each such arm supports a switch actuator or the like, with varying force transmission at different stages of depression of its corresponding key, the overall electrical-mechanical combination affording a response in terms of both actual results and kinesthetic feedback simulating a manual piano action.

    • A multi-pane flush closing window assembly for a vehicle that has a body enclosing a passenger compartment is secured in an opening in the vehicle body by a clamp ring fastened to the interior wall of the vehicle body. The improved window assembly includes at least one fixed sub-assembly and at least one sliding sub-assembly supported by a frame. The fixed sub-assembly has a sash, and removable fasteners extend through the peripheral edge of the sash into the interior side of the frame so that the fixed sub-assembly can be independently disassembled from the interior of the vehicle without removing the frame or the clamp ring. The sliding sub-assembly is removably secured to the frame by an improved multi-piece guide track and slide pin assembly that allows removal of the sliding sub-assembly without removing the frame. The slide pins are removably secured to opposite sides of the sliding sub-assembly.
