A method and apparatus for an improved rotatable safety cam lock fitting having ergonomically designed double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. Various configurations of the cam portions relative to each other are provided. Various lever locking assemblies may be used to prevent the cam levers from being inadvertently opened.

A variable crimp machine includes an actuator adjustment assembly including a dial that rotates about an actuation axis and a barrel positioned along the actuation axis within the dial. The barrel includes a first set of axially spaced markings corresponding to a first hose and a second set of axially spaced markings correspond to a second hose. The dial includes a first set of circumferentially spaced markings corresponding to the first hose and a second set of circumferentially spaced markings corresponding to the second hose. The first set of circumferentially spaced markings are used in concert with the first set of axially spaced markings to adjust an actuator for use with the first hose, and the second set of circumferentially spaced markings are used in concert with the second set of axially spaced markings to adjust the actuator for use with the second hose.

A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.

A pipe assembly includes an inner pipe member and an outer pipe member that is externally fixed to an end portion of the inner pipe member. The inner pipe has a thickness that is less than that of the outer pipe which is placed outside the end portion of the inner pipe member. An additional fixture member is placed outside the portion where the inner and outer pipes are fitted to each other. While the inner pipe, the outer pipe, and the additional fixture are in this state, an electromagnetic coil is placed inside the inner pipe at a position where the outer pipe and the additional fixture are to be fixed. The diameter of the inner pipe increases by applying a pulse current to the electromagnetic coil. The diameter of the outer pipe increases by the action of force applied when the diameter of the inner pipe is increased.

A joining method for members includes: providing a steel component 10 including insertion holes 14a and 15a, an aluminum pipe 20 having a hollow shape, and a support component 30; inserting the aluminum pipe 20 into the insertion holes 14a and 15a of the steel component 10; and enlarging the aluminum pipe 20 through deformation and joining the aluminum pipe 20 to the steel component 10 by press-fitting. The press-fit joining is performed while at least part of the support component 30 is disposed in a press-fitting region.

A plant for realizing fitted hydraulic hoses includes: a cutting station provided with a cutter configured such as to cut a hydraulic hose into a plurality of portions of hose; a storage station of a plurality of hydraulic fittings, each of which is able to be fixed to an end of a portion of hose into which the hydraulic hose is cut; a crimping station provided with a crimping press configured such as to crimp a hydraulic fitting to an end of the portion of hose; and a control and command unit operatively connected to the crimping press of the crimping station, configured for determining a blocking force of the crimping press according to an indicative parameter of the type of hydraulic hose cut in the cutting station.

Systems and devices for crimping a medical device and associated methods are disclosed herein. A crimping device configured in accordance with embodiments of the present technology can include, for example, a frame including a stationary plate, a movable member, and a plurality of blades arranged to form a channel and each including a pin that projects through a slot on the movable member and a corresponding slot on the stationary plate. The crimping device can be actuated to move the movable member relative to the stationary plate to drive the pins along paths defined by the slots to thereby drive the blades radially inward to crimp a medical device positioned within the channel.

A high-pressure tube compression fitting/flared fitting for use in combination with a thick-walled tube and a connection body wherein a sleeve is in engagement with a thick-walled tube. The sleeve is generally cylindrically shaped with the exterior thereof coated and then etched. The sleeve includes a first and second sharp inner circumferential biting edges which interengage and bite into and through the exterior of the end portion of the thick-walled tube and into the wall portion of the end portion of the thick-walled tube without narrowing the passageway through the thick-walled tube. The process for making the fitting includes placing an end portion of the thick-walled tube into engagement with a tube engaging surface of a tapered generally cylindrical wall of a guide rod.

An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion having an inwardly facing annular groove orientated transverse to the central axis; a shroud concentrically mounted on the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the inwardly facing annular groove of the shroud-receiving portion of the body; the axially-buckled radially-extending annular protrusion of the shroud and the annular groove of the shroud-receiving portion of the body forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

A structure formed by temperature difference includes an enveloped part, an enveloping part, and a low heat transfer layer. The enveloped part has a free section and an engagement section. The enveloping part defines at least one holding space corresponding to the engagement section. The holding space is dimensioned to be slightly less than the engagement section and can be thermally expanded to be larger than the engagement section by heating the enveloping part to reach a predetermined temperature difference over the enveloped part, so that the engagement section can be put into the holding space. When the enveloping part is cooled, the holding space can shrink, causing the enveloping part to tightly hold the engagement section. The low heat transfer layer, which has a thermal conductivity less than each of the two parts, is disposed in the holding space, between the engagement section and the enveloping part.
