A catheter 1 suitable for advancement through a body passageway of a patient. The catheter 1 comprises a catheter body 4 which is flexible to provide the necessary trackability for the catheter 1 to advance through a body passageway, and two stainless steel reinforcement wires 5 extending along the catheter body 4 which provide the necessary pushability to advance the catheter 1 through the passageway. The reinforcements 5 are positioned diametrically opposed to one another by approximately 180 degrees on opposite sides of the longitudinal axis of the catheter 1, and the catheter body 4 is relatively soft and twistable. This configuration enables the entire catheter 1 to spontaneously twist during advancement so that the reinforcements 5 orientate themselves along a plane of neutral bending during advancement of the catheter 1. In this way, any resistance to the trackability of the catheter 1 due to the stiff reinforcements 5 is minimized.

A fitting for joining pipes, tubes, or conduits improves coupling capability particularly to a large bore pipe, generally of 2 inches and larger in diameter. The fitting includes a substantially cylindrical sleeve and ring. The sleeve has an inner surface defining a bore, configured to slidably receive the pipe at an open end. The inner sleeve surface also includes protrusions, which deform the outer surface of the pipe upon swaging. The fitting also includes an outer surface having multiple stepped lands of ascending height relative to the open end. The ring has an inner surface configured to engage the multiple ascending steps on the inner sleeve surface. The inner surface of the ring has descending steps that are positioned to interfere with the multiple ascending steps on the outside of the sleeve. Axial motion of the ring causes the ring to slide over the sleeve and apply a radial swaging force directly to the multiple stepped sleeve. The swaging force makes the ring overcome the interference and push down on the multiple ascending steps of the sleeve, which swages the sleeve to the pipe. The multiple ascending steps of the sleeve are positioned relative to the descending steps of the ring, such that only one step at a time is swaged.

Disclosed is a device for tightening a shoelace, the device comprising a shoe main body formed with an opening and a tongue finishing an inside of the opening; a shoelace connecting opposite sides of the opening; a handle connected to at least one of shoelaces connecting the opposite sides of the opening; and a hook formed in rear of the shoe main body and holding the shoelace pulled by the handle.

A door-latching system for a sectional door with multiple door panels helps hold the door at its fully open position in case the door's counterweight torsion spring fails to do so. The door-latching system includes a latch assembly that moves between a maintained release position and a door-blocking position. In the door-blocking position, the latch assembly helps hold the door open by providing an obstruction to the door panels. In the maintained release position, the latch assembly allows the door to move freely between open and closed positions without the door-latching system clacking as the door panels or their guide rollers travel past the latch assembly. Movement of the door panels automatically shifts the latch assembly from its release position to its door-blocking position, and manual actuation returns the latch assembly back to its release position. The latch assembly is especially suited for mounting to a track that guides the movement of the door panels.

Preferred angular displacements for a wide range of users and loads positioned in and on the luggage case have been found to be at about 17° and 35° from the vertical position.

Described is a sealing system for use at high pressure. End-face seals minimize the sealing radius and therefore allow various fittings—including known ferrule fittings—to be used in high-pressure systems. End-face seals at such high pressure may require smooth surfaces. In order to reduce cost, an end-face preparation tool forges a dimple into the end face to mechanically deform and smooth the surface.

Disclosed is a magnetic drive for an electrical switch, including a linear armature (26) displaceable between two ends positions, a shunt body (27) mounted at a distance from said armature and means (24, 25, 30, 31) for generating a magnetic field. The magnetic field exerts a force on the armature (26) retaining the latter in the end positions. By joining the shunt body (27) with the armature (26), the course of the flow lines of the magnetic field are changed in such a way that the retaining force exerted on the armature (26) is reduced and the latter is displaced to the other end position, optionally by a force exerted externally on the armature (26), and retained in the position by the magnetic field. Disconnection is effected by the shunt body (27), were after being joined with the shunt body (27) the armature (26) is moved from the end position opposite the shunt body (27) to the end position facing the shunt body (26). Fixing means (37-40, 42-45) are especially provided which hold the shunt body (27) in the end position opposite said shunt body and which joins the shunt body with the armature (26) when the electric switch (1) is disconnected requiring little energy / force expenditure.
