  • Patent number: 7950868
    Abstract: A modular crankshaft features a connection system between modules that features opposed female receptacles. A pin having opposed beveled ends and hydraulic passages with it is inserted into the opposed receptacles. A pair of seals is disposed on the beveled ends and straddles a hydraulic fluid outlet. The crankshaft wall that defines each receptacle is designed to flex in response to applied hydraulic pressure between the seals on the tapered pin portion. A notch at the base of the receptacle in the crankshaft reduces stress concentration and enables the wall defining the crankshaft receptacle to come back when hydraulic pressure through the pin is removed. The opposed crankshaft receptacles are flanged to allow them to be pulled together over the pin. An interference fit results around the pin after the flanges are mated and the hydraulic pressure is removed.

  • Publication number: 20090028634
    Abstract: In bolted joints having a plurality of bolts, the receiving bores for the bolts in the parts to be joined are usually made by joint boring of the bolt eyes of these parts. In cases in which this approach is not possible, an offset of the bolt bores arises. The proposed solution is intended to compensate for this offset during the assembly of the parts. In order to bring about this compensation, slotted eccentric bushings are inserted into the finished-size bores of the bolt eyes, which bores respectively receive a bolt, and are adjustable by rotation such that the axes of their inner bores coincide, so that the bolt is insertable which establishes the joint. This solution is suitable for all bolted joints having a plurality of bolts, in which the parts to be joined cannot be jointly bored.

  • Patent number: 7001097
    Abstract: A joint assembly for joining first and second tubular members. The first member has flanges extending from walls of an end segment. The walls of the end segment define a receiving opening. The second member has walls and a protrusion having sides extending from the walls to an end of the protrusion. When the members are joined the protrusion is received in the opening of the end segment so that the sides of the protrusion are in facing engagement with the walls of the end segment and the flanges engage the walls of the second member. The members are secured together at some of the engaging surfaces. The protrusion reduces stress on the flanges and increases the mechanical strength of the assembly.

  • Patent number: 6869081
    Abstract: A gasket system for sealed interfaces utilizes a carrier ring having inner and outer compression stops to account for and control flange rotation effects in order to achieve a uniform and constant gasket seating stress across the sealing region. The inner compression stop provides a fixed fulcrum for flange rotation. The inner and outer compression stops have different heights, dependent upon the characteristic flange rotation, that allow the orientation of the sealing material to be angularly matched to the flange side profile and that allow the sealing material to be fully captured within the sealing region upon full compression, minimizing creep relaxation. A visual compression indicator on the circumference of the carrier ring permits assembly of the interface without the use of specialized or calibrated tools.

  • Patent number: 6829872
    Abstract: A connecting plate for connecting I-beams together. The connecting plate contains at least two plates that each have a series of holes drilled in them. These series of holes are drilled offset from each other in each plate. The connecting plate can be in the form of a flat face, an L-shaped plate or a partially H-shaped plate. The offset holes on these plates allow the plates to be connected to a first I-beam first, and then connected to a second I-beam. This design allows a user to forgo coupling the first I-beam, the coupling plate and the second I-beam together all at the same time which improves the safety and efficiency of coupling I-beams together.

  • Patent number: 6748967
    Abstract: Couplers for joining actuators to valves are configured to allow their affixment to different makes and models of actuators and valves, thereby allowing an off-the-shelf S coupling solution and avoiding the need to specially construct a coupler which is only adapted to connect whatever valve and actuator that are desired for coupling. The couplers include a shaft/stem bore which accommodates the torque-transmitting components of the valve and actuator to be coupled, and sets of affixment holes surround the shaft/stem bore, with these affixment holes being arrayed in patterns matching those of different common valves and actuators. Thus, a coupler may affix to different valves or actuators provided the appropriate affixment holes are chosen. The couplers may be formed as single-piece or multi-piece units.
