Abstract:
A fastening device for fastening a cover to a body of an explosion-proof enclosure can include a bracket having a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, where the top side includes an engagement, portion, where the first angle is substantially parallel to an under side of the body flange, and where the second angle is substantially parallel to a top side of the cover flange. The fastening device can also include a cam fixedly coupled to an outer surface of the cover flange and hingedly coupled to the engagement portion. The fastening device can further include a lever fixedly coupled to the cam and having a closed position and an open position.
Abstract:
A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices. Each fastening device can include a first load distributing member disposed on a body flange of a body of the explosion-proof enclosure. Each fastening device can also include a second load distributing member disposed on a cover flange of a cover of the explosion-proof enclosure. Each fastening device can further include a fastener positioned atop the first load distributing member, where the fastener traverses the first load distributing member, the cover flange, and the body flange. Each fastening device can also include a fastener receiver positioned under the second load distributing member and mechanically coupled to the fastener.
Abstract:
A latch assembly (10) is mounted in an aperture formed in a first member (82) for releaseably retaining the first member (82) against a corresponding second member (84) and in a latched position. The latch assembly (10) includes a handle (12) which is adapted for pivotal rotation, a shaft (14) connected with the handle (12) for movement corresponding with the pivotal rotation of the handle (12) and a latching member (16) on the shaft (14) which is adapted to engage the second member (84) in the latch position when the handle (12) is pivoted to the closed position.
Abstract:
An enclosure can include a top enclosure portion having a top flange and a first top engagement feature. The enclosure can also include a bottom enclosure portion mechanically coupled to the top enclosure portion, where the bottom enclosure portion has a bottom flange that mechanically couples to the top flange and a first bottom engagement feature that mechanically couples to the first top engagement feature. The enclosure can further include a first fastening device mechanically and movably coupled to the first top engagement feature and the first bottom engagement feature. The first fastening device, in an engaged position, can maintain a flame path between the top flange and the bottom flange. The first fastening device, in a disengaged position, can fail to maintain a flame path between the top flange and the bottom flange.
Abstract:
A- foldable stroller, chassis has left and right sides, a front end, and a rear end. The chassis has a chassis joint (68) between the left and right sides, a front wheel section (64) extending toward the front end, and a rear wheel section (66) extending toward the rear end and coupled to the front wheel section at the chassis joint. The, front' and rear wheel sections are pivotable away from one another to an in-use configuration and toward one another to a folded configuration. A fold latch mechanism (100) is positioned adjacent the chassis joint between the left and right sides and is reconfigurable between a latched condition securing the chassis in the in-use configuration and an unlatched configuration. A part of the mechanism is carried on the front wheel section and a part of the mechanism is carried on the rear wheel section.
Abstract:
A closure mechanism for pressure test chambers for testing electronic components, in particular ICs, has a plurality of pivoting jaws (11). At least some of the pivoting jaws (11) have at least one lifting apparatus (15) which can be advanced to two interacting cavity elements (1, 2), which surround a cavity (5), by means of the pivoting jaws (11). Furthermore, at least some of the pivoting jaws (11) have at least one locking device (23) in order to move spacer elements into an intermediate space (25) between the associated pivoting jaws (11) and the compressed cavity element (1), as a result of which the tightness of the cavity (5) is maintained even when the lifting apparatuses (15) are retracted.
Abstract:
A system for making a connection between the interior and exterior of a compartment, comprising a door opening through the compartment wall, a connector body which can engage with the wall, and having a connection port through it, and a removable cover on the connector body. The body is engaged with the door opening, and an inner door within the compartment engages and removes the cover. A preferred construction creates a single line of confidence seal. The system is particularly suited for sterile compartments.
Abstract:
An enclosure system that can include an enclosure cover comprising a receiving feature. The enclosure system can also include an enclosure body mechanically coupled to the enclosure cover. The enclosure system can further include a cover release mechanism mechanically coupled to the enclosure body and disposed, at least in part, within the receiving feature, where the cover release mechanism is movable between a first position and a second position. The enclosure cover and the enclosure body can be mechanically coupled to each other when the cover release mechanism is in the first position. The enclosure cover and the enclosure body can be, at least in part, separated from each other when the cover release mechanism moves to the second position from the first position.
Abstract:
A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices. Each fastening device can include a first load distributing member disposed on a body flange of a body of the explosion-proof enclosure, and a second load distributing member disposed on a. cover flange of a cover of the explosion-proof enclosure. A fastening device can also include a securing member having a top end disposed on the first load distributing member and a bottom end disposed on the second load distributing member. A fastening device can further include a cam rotatably coupled to and positioned atop the first load distributing member.
Abstract:
A wafer container (100), and methods of constructing a wafer container (100). The wafer container (100) has an enclosure portion (102) with at least a top (104), a bottom (106), a pair of opposing (108,110) sides, a back (112), an open front (116), and a door (114) to close the open front (116). The door (114) includes a door chassis (150) with at least a first latching mechanism (160). The latching mechanism (160) has a rotatable cam member (170) and at least one latching arm (162). The latching arm (162) has a bifurcate cam follower portion (166) that engages with the periphery of the cam member (170).
