clamping (Total 59259 Patents Found)

An improved clamping device for maintaining clamping pressure in a winding of a power transformer during its useful life. A remotely actuated hydraulic jack, or similar device, is used to initially apply a clamping force to the transformer winding. A spring-loaded mechanical follow-up device maintains the coil clamping...
A quasi-liquid vise is provided for clamping irregularly shaped workpieces which comprises an open-topped vessel into which a workpiece may be inserted, a particulate fluidizable material located within and, substantially filling said vessel, pressure means connected to said vessel for introducing a gas or fluid therei...
A mold clamping device includes a frame, a fixed base for supporting a first mold, the fixed base being fixedly mounted on the frame, a movable base for supporting a second mold, the movable base being movably mounted on the frame in confronting relation to the fixed base, first means on the frame for driving the movab...
A device and a method for fastening, clamping, or adjusting a molding part to a body-mounted part are provided. To allow the absorption of large tensile forces, a tensioning element designed as a tension strut is provided, which includes at least one oblong element made of fiber-reinforced plastic. The length of the te...
Multiple disc read and write systems and two-way disc clamping mechanisms thereof are provided. A two-way disc clamping mechanism includes a frame, two parallel support components, two parallel clamp components, an L-shaped drive component, and a spring. Space between the two parallel clamp components is a clamping spa...
A switch mode power supply apparatus includes a transformer, a main switching device to adjust a power supply supplied to a primary coil of the transformer, an active clamping circuit to suppress a voltage stress of the main switching device, and a control circuit to control a clamping operation of the active clamping ...
Breakage of the actuator moving the movable platen in the clamping device of an injection moulder is prevented. The clamping device includes a movable platen shifting device increasing and decreasing a horizontal distance between the movable platen ( 3 ) and the fixed platen ( 2 ). It includes an actuator ( 41 ), a cle...
A lateral MOSFET having a substrate, first and second epitaxial layers grown on the substrate and a gate electrode formed on a gate dielectric which in turn is formed on a top surface of the second epitaxial layer. The second epitaxial layer comprises a drain region which extends to a top surface of the epitaxial layer...
