  • Patent number: 9075028
    Abstract: An airborne substance detector includes an air intake that sweeps through a fixed area, and a fan that draws air toward an effluence detection device that analyzes the air for one or more substances, such as explosives. The air intake may be a series of tubes of a rotary gate, with multiple sets of tubes that rotate about a central axis. The fan or blower draws air through holes in the tubes, and through a manifold that directs air to the effluence detection device from a single set of tubes at a time. In addition the detector may include a heater that may enhance vaporization of substances to be detected. The effluence detection device, the manifold, and the fan may be located in an enclosure at the top of the rotary gate. After detection, a decontamination procedure may be initiated to purge the system of the substance that was detected.

    Abstract: An active rinse shield designed to protect electrofill chemical baths from excessive dilution during rinse sprays on the semiconductor wafer. The shield uses overlapping blades to cover the bath, making a physical barrier between the bath chemistry and the wafer rinse water. The blades are interconnecting ribs that actuate around a common pivot axis. A linear mechanical actuator controls the blade movement, moving the top-most blade, which in turn, moves an adjacent lower blade. Each upper blade is interconnected to an adjacent lower blade by upper and lower ledges, a pivot boss and interlocking cut, and a curved ledge on each blade's body surface. The interconnecting features allow the blades to move one another out for extension or in for retraction. The interlocking blades are inclined above one another, forming grooves to redirect the rinse water away from the chemical bath.

An electromagnetic brake generates a moment to retain the driven part in the starting position when electrical current is supplied, and allows the driven part to pivot from the starting position when electrical current is not supplied. The driven part is held in the starting position when the driven part returns to the starting position and no moment is generated by the electromagnetic brake.

  • Patent number: 6925756
    Abstract: The ingress to and egress from an access restricted compartment, such as the cockpit in an aircraft, is controlled by a revolving gate (1) rotatably mounted in a stationary gate frame (2). The revolving gate (1) has a single gate opening (11) and is rotatable about its central longitudinal axis through predetermined or preselected angular sectors to bring the gate opening (11) either into alignment with any one opening (21) of at least two frame openings (21) at a time, to provide ingress or egress, or to cause said single gate opening (11) to face a wall (2A) of said stationary gate frame (2) or a closed door (51) in said stationary gate frame (2) to close the gate (1). In the closed position of the gate (1) escape from the gate (1) is prevented by locking the gate in its closed position by at least one arresting bolt that is electrically controllable. The atmosphere in the revolving gate (1) is also controllable for incapacitating any unauthorized intruder.

  • Patent number: 6742301
    Abstract: A revolving door has a metal detection function. A metal detector will detect a predetermined sufficient amount of metal. The door will not allow a user with such a sufficient amount of metal to pass through. One also cannot pass a gun or other metal object through the revolving door. The door itself is modified by having its metal glass wing holding supports extend only for a portion of the radius of the door wing. In another embodiment, a security revolving door is combined with metal detection security.

  • Patent number: 6725603
    Abstract: An emergency exit revolving door apparatus includes a revolving door assembly that is generally comprised of a ceiling panel, a floor panel, and a pair of curved vertical panels extending therebetween to form a rigid, conjoint assembly. The revolving door assembly is disposed in a door opening of a building, and is mounted on a dolly that is disposed within a channel inset in the floor and extending outwardly from the exterior of the door opening. In an emergency situation, if a throng of people rush to the revolving door and push outwardly on it with sufficient force, the door assembly will be driven outwardly by the force. The dolly will translate along the channel so that the entire revolving door assembly translates outwardly from the door opening of the building and clear the door opening to enable a substantially unobstructed emergency exit path.

  • Patent number: 6715234
    Abstract: A turnstile entry gate comprising at least two, at equiangular distances on an arm carrier (5) mounted barrier arms (2-3), the arm carrier (5) being by way of a remote-controlled barrier device (6) arranged to permit or to prevent turning in at least one rotational direction. The arm carrier (5), or at least one of disks (7; 8) arranged near and connected thereto exhibits a magnetic strip (9) preferably extending circumferentially and adapted, by way of sensors, to indicate the position and the direction of movement of the turnstile. The barrier function of the device (6) is normally mechanically disconnected when one of the barrier arms (2-4) in the turnstile is in its home position, i.e. horizontally oriented, the sensor and electronic systems only checking that a passage has taken place and that, with the aid of e.g. a spring and/or hydraulics, the turnstile can assume its next home position.
