285038000 | Handle or handwheel for rotary engagement | 8 |
20090243281 | CONNECTORS HAVING FEATURES TO FACILITATE OR HAMPER TIGHTENING AND/OR LOOSENING - A connector includes gripping features. The gripping features can comprise two surfaces that generally oppose each another. Each surface can be configured to facilitate or hamper rotation of the connector in a direction. Some embodiments can hamper tightening and facilitate loosening of the connector. Other embodiments can facilitate tightening and hamper loosening. Still other embodiments can hamper both tightening and loosening. Yet other embodiments can facilitate both tightening and loosening. | 10-01-2009 |
20100032940 | PIPE JOINT, REFRIGERATING DEVICE, AND HEAT PUMP WATER WARMING DEVICE - A pipe joint has a joint body | 02-11-2010 |
20100230950 | Aseptic Coupling Devices - Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device, removing a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device, and rotating a locking clip on the first aseptic coupling device to compress a first seal member of the first aseptic coupling device with a second seal member of the second aseptic coupling device to form a sterile fluid passageway. | 09-16-2010 |
20100320748 | Device and Method for Fluidic Coupling of Fluidic Conduits to a Microfludic Chip, and Uncoupling Thereof - A system for fluidic coupling and uncoupling of fluidic conduits and a microfluidic chip, wherein the fluidic conduits are connected mechanically to a first structural part and the microfluidic chip is carried by a second structural part. The structural parts are moved perpendicularly toward and away from each other by means of a mechanism provided for this purpose. Outer ends of the fluidic conduits can thus be moved over a determined distance substantially perpendicularly to the outer surface of the microfluidic chip and connecting openings in the outer surface of the microfluidic chip. This enables accurate realization of fluidic coupling and uncoupling without the occurrence of undesirable moments of force and with minimal risk of damage to the fluidic conduits or the connecting openings. With such system requirements which can be set in respect of convenience, speed, temperature resistance, sealing, chemical resistance, reproducibility and so forth, can be fulfilled. | 12-23-2010 |
20100327576 | Pipe Coupler and Gasket With Positive Retention and Sealing Capability - A coupler for joining a pipe to another pipe, a tee, or other fitting, and more particularly, to a coupler which provides positive retention of the gasket about the circumference of the coupler sufficiently to precisely position and hold the gasket during placement about pipe ends and/or fittings to be coupled, and which provides controlled circumferential compression of the gasket during coupling, for positive sealing when the coupler is closed, while allowing one handed handling and operation during placement and coupling, such that the other hand can be used for supporting a pipe to be coupled, and which is operable for releasing and breaking loose the coupler and associated gasket from a pipe during uncoupling. | 12-30-2010 |
20110031739 | CONNECTION-STATE CHECK TOOL USED FOR ASSEMBLING A PIPE COUPLING - A connection-state check tool is used for assembling a pipe coupling having a connection pipe and a coupling member. The connection-state check tool comprises a pair of arms and a frame-shaped handle. The pair of arms has claws that can clamp down on the coupling member, and are engageable with the connecting pipe. The frame-shaped handle is connected to the arms. The handle has a split at a position opposite to the arms. The handle has elasticity, due to which the split can expand. | 02-10-2011 |
20130320663 | COUPLING DEVICE FOR FLUID LINES - A coupling device for fluid lines includes a female part having a rotatable locking arm with a cam, and a male part defining a longitudinal channel and a circumferential groove on its external surface. The male part is inserted into the female part by rotating the locking arm to its unlocked position, aligning the longitudinal channel with the cam, and sliding the cam within the longitudinal channel. The male part is locked into the female part by rotating the cam within the circumferential groove away from the longitudinal channel, and rotating the locking arm into its locked position so that the cam protrudes further into the circumferential groove. Even when the locking arm is rotated to its unlocked position, the cam engages the circumferential groove to retain the male part within the female part unless the cam is rotated within the circumferential groove into alignment with the longitudinal channel. | 12-05-2013 |
20140131992 | HYDRAULIC LINE ATTACHMENT DEVICE AND METHOD - A hydraulic line attachment device is provided. The hydraulic line attachment device comprises a first assembly comprising a first frame constructed for holding a plurality of first hydraulic line couplers and a first coupling member; and a second assembly comprising a second frame constructed for holding a plurality of second hydraulic line couplers and a second coupling member constructed to engage the first coupling member and align the plurality of first hydraulic line couplers with the plurality of second hydraulic line couplers. At least one of the first coupling member and the second coupling member comprises an arm constructed to engage at least one of the first frame and the second frame and engage the other of the first coupling member and the second coupling member. The other of the first coupling member and the second coupling member comprises a cam that engages the arm to provide tightening of the first assembly relative to the second assembly. A method for using a hydraulic line attachment device is provided. | 05-15-2014 |
