摘要： A power tool constructed in accordance to one example of the present disclosure can include a repositionable tool accessory. The repositionable tool accessory can be selectively coupled to a first mounting structure on the tool. The repositionable tool accessory can include a tool accessory housing, a rod, a roller, and a locking knob. The tool accessory housing can define a first rod opening and include engaging structure that is configured to cooperatively mate with the first mounting structure. The rod can slidably translate along the first rod opening. The roller can be rotatably coupled to a distal portion of the rod. The locking knob can be movable between an unlocked position wherein the rod is freely translatable along the first rod opening to locate the roller at different locations relative to the output member, and a lock position wherein the rod is fixed relative to the tool accessory housing.

摘要： A manifold includes a plurality of inlet passages provided in fluid communication between an inlet and an outlet passage. A housing retains a pressurized gas cartridge in sealed fluid communication with each of the inlet passages. A check valve is located in at least one of the inlet passages. The check valve is biased to a closed position that prevents gas from flowing through the check valve to the inlet of the inlet passage. Thus, gas cannot exit through the inlet when a pressurized gas cartridge is not sealed thereto. The housing retains a viscous product cartridge and forms a gas enclosure separated from a product enclosure by a movable wall. The gas from the pressurized gas cartridges passes into the gas enclosure and generates a force on the movable wall to dispense product from the product cartridge.
摘要翻译：歧管包括设置成在入口和出口通道之间流体连通的多个入口通道。壳体保持与每个入口通道密封的流体连通的加压气体盒。止回阀位于至少一个入口通道中。止回阀被偏压到关闭位置，以防止气体流过止回阀到入口通道的入口。因此，当加压气瓶未被密封到其中时，气体不能通过入口排出。壳体保持粘稠的产品盒，并形成一个通过活动壁与产品外壳隔开的气体外壳。来自加压气瓶的气体进入气体外壳，并在可移动壁上产生一个力，从产品盒中分配产品。

摘要： An inlet is adapted to receive pressurized gas from a CO2 gas cartridge. A variable compression member has a normal height, under normal operating temperature conditions, adapted to provide a normal compressive force between the gas cartridge and the inlet to effectively seal the gas cartridge to the inlet. The variable compression member also has a reduced height, under heightened temperature conditions, adapted to provide a reduced compressive force between the gas cartridge and the inlet to allow pressurized gas to escape between the gas cartridge and the inlet. A seal member is compressed between the gas cartridge and the inlet. The inlet may be part of a pneumatic dispensing device. The gas inlet is in fluid communication with a gas enclosure to enable pressurized gas delivered through the inlet to provide a dispensing force on a product cartridge to cause dispensing of the viscous product.

摘要： A power tool has a mechanism for ejecting a battery pack which includes a receiving frame which defines a cavity to receive a battery pack. A receiving member is adjacent the cavity. The receiving member meshes with a member on the battery pack to hold the battery pack in the cavity. A biasing member is in the cavity adjacent the receiving member. The biasing member ejects the battery pack from the ejecting mechanism. A member retains the biasing member in the cavity. The member guides a portion of the battery pack meshing with the receiving member into contact with the biasing member such that when the battery pack is locked onto the frame, the biasing member is in a compressed condition and when the battery pack is an unlocked position, the biasing member ejects the battery pack from the frame.

摘要： A computer-implemented system (10) for designing communications circuits includes one or more route plans (16) each with a first route point group (38) for a first circuit end point (34), a second route point group (38) associated with a second circuit end point (34), and one or more routes (32) connecting the first and second route point groups (38). Each route (32) is available for use in designing the circuit. A design engine (12) accesses a particular route plan (16), selects a route (32) according to the route plan (16), and automatically assigns the selected route (32) to the circuit in designing the circuit. The design engine (12) may select the particular route plan (16) from among multiple route plans (16) according to a service application (14) that is automatically derived from an associated circuit order. The design engine (12) may assign equipment to the circuit at one or more points along the selected route (32) according to an equipment assignment template (18) specifying characteristics of the equipment. The design engine (12) may select the template (18) from among multiple templates (18) according to a service application (14).

摘要： Insulating oil in electric power transmission devices such as a transformer is filtered for removal of accumulated water and carbon particles. The filter and circulation pump are usually located in a separate cabinet external to the transformer with circulation conduits connecting the filter, the pump and the transformer. To prevent environmental contamination by leaks or ruptures in the oil circulation conduits, secondary or sleeving conduits surround and protect the circulation conduits and additionally provide an independent leak flow conduit back to the filter cabinet dry sump. An accumulation of oil in the dry sump actuates a fluid sensor to transmit an alarm signal.

摘要： A viewing window for covering an aperture in a hand-held circular saw includes an optically transmissive member adapted to be coupled with the guard. The member is movable between a closed position, wherein the member substantially covers the aperture, and the open position, wherein the member at least partially uncovers the aperture, to allow the cleaning of the member. A structure is provided for biasing the member to the closed position.
