A unique collapsible apparatus for supporting an article; the apparatus has at least a first, second, and third leg assembly, an upper end of each leg assembly pivotally secured to extend from an upper support member in a generally symmetrical fashion. A lower end of each leg assembly pivotally secured to extend from a lower support member (which may be in the shape of a collar). Each leg assembly has a unique hinge-fitting interconnecting a first and second elongated subassembly; a hinge-fitting may comprise a first and second extension pivotally enjoined. Each hinge-fitting permits a pivot range of rotation; preferably, this pivot range may be up to 90-degrees, up to 170-degrees, or just under 180-degrees. The elongated subassemblies may each be comprised of a plurality of telescoping tubular sections adapted for interlock. The telescoping tubular sections of an elongated subassembly may be sized for interchangeability with telescoping tubular sections of another elongated subassembly. Upper support member may have a plurality of fork extensions to which upper ends of the leg assemblies are pivotally secured. Upper support member may have an aperture for accepting an article, e.g., aperture will be sized to accept the periphery of the article. Lower collar support member may be adapted for accepting a lower-end of the article for placement on / in connection with a ground.

The systems and methods of present invention invoke an elevator communication system for providing communication between a plurality of hall fixture devices and at least one elevator system controller. The elevator communication system includes at least one elevator door interlock wiring circuit, which has a first and a second portion. A first transceiver device is coupled to the first portion of the door interlock wiring for transmitting and receiving signals between the at least one elevator system controller and the plurality of hall fixture devices over the interlock wiring. A second transceiver device is coupled to the second portion of the door interlock wiring for transmitting and receiving the signals between the at least one elevator system controller and the plurality of hall fixture devices over the interlock wiring.

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

A control system for a BBC on a mower comprises a pivotal bail and a pivotal housing that is linked to the BBC. If a push member on the housing is pushed inwardly from the side of the housing before the bail is pivoted, then a pin moves to a blocking position behind the bail. Subsequent pivoting of the bail will pivot the housing to actuate the BBC. A channel in the housing frictionally grips the bail to prevent rebound of the bail when a spring force resets the housing and the bail to their initial positions after the operator releases the bail. Movement of the push member also closes an interlock switch which will kill operation of the engine if a grass discharge outlet on the mower is uncovered.

The present invention relates to a circuit breaker having separate restrained and unrestrained zone selective interlock setting capability. A circuit breaker system and method having zone selective interlock features with separate restrained and unrestrained setting capability is provided. The system and method include the transmission of a selective interlock signal from a downstream circuit breaker to an upstream circuit breaker in the event of a fault condition. The upstream circuit breaker upon receipt of this signal changes the tripping response of the second circuit breaker to a restrained mode. The circuit breakers include features enabling the user to modify and adjust both the restrained and unrestrained trip curves associated with both the restrained and unrestrained modes of operation.

An interlock vessel having an air-tight body with opposing ends. A portion of the body is designed to fit into a decompression (hyperbaric) chamber, wherein a diver or a patient undergoing a decompression treatment is positioned. The opposing ends are closed by pivotally moveable doors and locking assemblies that retain the doors in a closed position until the pressure inside the decompression chamber and the exterior of the chamber can be equalized. The outer door has two locking systems: (a) an interlock system and (b) a safety / delay locking system. Both locking assemblies are manually operated.
