  • Patent number: 4429711
    Abstract: In the preferred and illustrated embodiment, a multivalve manifold control and interlock system is set forth. The multivalve manifold comprises three valves arranged within a valve body, wherein valve stems with optional handles are located above the valve body to be gripped and rotated. The valve body encloses three ball or plug valves. They are switched by rotation. Each stem supports a circular disk, and the three stems are equipped with three circular disks which interlock. Certain arcuate notches are cut in the circular disks. The arrangement of the notches limits the sequence in which the valves are opened and closed. Moreover, opening and closing is constrained to the sequence required for safe operation of the multivalve manifold. Further, a lock bar is incorporated, and is profiled to fit with the valve stems for locking.

  • Patent number: 4413491
    Abstract: An anti-theft device for locking the steering of an automobile vehicle comprises a crown gear (3) which is rotatable with the steering shaft (1) and has teeth (8) separated by concave sections having a part-circular profile (9), and a locking element on a spindle positioned parallel to the steering shaft (1) and rotatable by a lock (17), the locking element comprising a finger (10) having a length substantially equal to the radius of the concave sections (9) of the crown gear (3) and an outer part-circular face (14) of the same radius as the concave sections (9). The face of the locking finger engages a concave section to prevent rotation of the crown gear and steering shaft in the locked position and the finger is completely out of engagement with the concave sections and gear teeth to allow rotation of the crown gear and steering shaft when in the unlocked position.
