A control push-button station for plants comprises a box-like body (2) housing therein a plurality of electric contacts for one or more circuits of the plant, and having a side wall (3) upperly closed by an upper wall (4), an emergency button (6) located on said upper wall (4) and electrically connected to at least one first pair of electric contacts, at least one electric device (7, 8, 9, 10) located on the upper wall (4) and electrically connected to at least one second pair of electric contacts. The control push-button station comprises a protection cover (12) adapted to be movably associated with the box-like body (2) to move between an open position in which the electric device (7, 8, 9, 10) is accessible and a closed position in which the electric device (7, 8, 9, 10) is not accessible to an operator, with the emergency button (6) being accessible in both open and closed positions.
摘要:
A handle assembly for a power tool, such as an angle grinder, including first and second handle portions for gripping the power tool, the first handle portion extending substantially transverse to the second handle portion. The handle assembly also having a trigger including an elongate portion associated with the first handle portion and a flange portion associated with the second handle portion and a switch for operating the power tool actuated by movement of either the elongate or flange portion of the trigger relative to the first or second handle portions respectively.

A stiff, metallic hub (40) for an energy storage device is disclosed. The hub (40) produces a critical velocity that is significantly greater than the design operating speed of a flywheel assembly (10) so that resonant frequency is never reached during normal operation of the flywheel assembly (10). The hub (40) comprises a central core section (70) that maintains a tight interference fit with the rotating shaft (25); an outer rim section (90) that maintains a tight interference fit with the high-strength, low-density composite fiber rim (20), in which energy primarily is stored; and a web section (80) situated therebetween and extending radially from the shaft (25). At high operating speeds, the outer rim (90) expands radially commensurate with the composite rim (20) so that enough of the outer rim (90) remains in tight interference fit with the composite rim (20) to substantially minimise vibrations.

A control console housing (32) is provided with a control aperture (76) through which the control lever (34, 36) extends. The housing (32) has enclosing walls defining an interior that typically houses a portion of the control linkage (40). The enclosing walls have an interior surface (80) and an exterior surface (78). A rigid shield (82) in the form of a circular disc is provided with a central opening (84). The circular disc (82) is slidably mounted on the control lever (34, 36). The disc (82) is provided with a top side (86) that is in free floating contact with the interior surface (80) of the control console housing (32). The free floating contact is maintained by a spring (90) that extends between the control linkage (40) and the bottom side (88) of the disc (82). The spring (90) biases the shield (82) upwardly so that the top side (86) of the shield (82) is in contact with the interior surface (80) of the housing (32) thereby covering the control aperture (76). The spring (90) comprises a coil spring defining an internal cylinder that is aligned with the central opening (84) and through which the control lever (34, 36) extends.

A composite link comprising a fiber reinforced composite tube (20), an end fitting (24) on each end of the tube (20) and layers of resin impregnated fiber (44) wound over the end fittings (24) and tube (20). The fiber (40) is laid in a primary layer (46) formed by winding longitudinally over the end fittings (24) and a secondary layer (50) wound transversely around the primary layer (46) and the tube (20). The tube (20), fitting (24) and layers of fiber (46 and 50) are encased in a layer of shield material such as a paint or a polymer.

摘要:
The present invention discloses methods and apparatus for winding wire onto the slots on armature lamination stacks. More specifically, the present invention is directed to methods and apparatus for increasing time the winding components are operating on an armature winding system. The invention includes a loading/unloading unit and a holding unit that may be operated independently under most circumstances. The independent operation enables the winders of the present invention to operate at increased duty cycles, thereby increasing throughput. Additionally, the apparatus of the present invention increases the likelihood that armatures remain properly indexed during the loading transfer process to further increase system efficiency.

An extension unit (50, 60 or 70) is connected to the main body (10) of a controller provided with an analogue direction key (12), a digital direction key (14), indicating buttons (20a-20z), indicating levers (22l and 22r), etc. When the unit (50) having a light emitting section (52) is connected to the controller, a cordless controller becomes available. When the unit (60) having a photodetecting section is connected, a gunshot game for shooting enemies on the monitor screen can be played. When the unit (70) having a vibrating section (75) is connected, a realistic gunshot game can be played by vibrating the main body (10). Therefore, a new function can be added to the conventional controller freely without changing the main body (10).
摘要:
The present invention relates to an applied load accepting band (12) for a centrifuge rotor (10) that is configured such that, while rotating, the applied loads on the band (12) are balanced by the tension in the band (12), so that during rotation the band (12) is subjected only to a tensile force.
