摘要： An automatic oil return structure is provided. The automatic oil return structure has an oil storage bag, a piston, and a main body assembly. The piston has an oil storage chamber. The main body assembly has a main channel, a piston oil channel, a pressure regulating channel, a control channel, an operation channel, a minor channel, and an oil return channel. When the pressure of the main channel achieves a limit pressure, the pressure pushes the control blocking assembly away such that the pressure regulating channel communicates with the communication channel, and the pressure also pushes the operating assembly away such that the minor channel communicates with the return channel. At the same time, the pressure of the oil storage chamber pushes the oil blocking assembly, so as to isolate the oil storage chamber from the main channel, and the oil storage chamber communicates with the oil return channel.

摘要： The invention relates to a blank holder for a dental milling machine. The blank holder has a clamping frame with a receptacle for a blank. The clamping frame includes a first frame part and a second frame part which are pivotable relative to one another to open the receptacle. A first clamping face is formed on the first frame part and a second clamping face is formed on the second frame part. The clamping faces engage an outer periphery of the blank with the clamping frame closed. To configure a blank holder so that the blank is fixed in the clamping frame in a play-free manner, provision is made to form one of the clamping faces on an annular clamping ring. The clamping ring is held on a frame part and is displaceable counter to a force in the axial direction.

摘要： A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

摘要： An apparatus configured to structurally replace a cracked weld in a nuclear plant may include: a first body portion that includes a first gripping portion; a second body portion that includes a second gripping portion; a wedge portion between the first and second body portions; and/or an adjustment portion. The first body portion may be configured to slidably engage the second body portion. The wedge portion may be configured to exert force on the slidably engaged first and second body portions. The adjustment portion may be configured to increase or decrease the force exerted by the wedge portion on the slidably engaged first and second body portions. When the adjustment portion increases the force exerted by the wedge portion on the slidably engaged first and second body portions, a distance between the first and second gripping portions may decrease.
