A conduit locking device includes a housing having a first end, a second end, and a sidewall disposed between the first end and the second end. The conduit locking device may further include a slide engaged with the sidewall of the housing, the slide including an extension arm and an end portion structurally configured to engage with an inner wall of a conduit. The slide may be extendable via the extension arm from a first position substantially adjacent to the sidewall of the housing to a second position disposed away from the sidewall of the housing, where, when in the second position, the slide is configured to retain the conduit locking device at a fixed position within the conduit through the engagement of the end portion with the inner wall of the conduit.

A latching device with a blocking device that is capable of preventing unintentional opening of a door or a flap in the case of a crash. The blocking device includes a pyrotechnic gas generator. The pyrotechnic gas generator triggers in the case of a crash and moves a blocking element into a blocking position which prevents opening of the locking mechanism of the latching device.

An improved foot pull for hands free opening of a door is described. The design provides a more ergonomic engagement of the user by providing an angled plate to engage their foot the plate further including a region treated to prevent slippage of the users foot off of the plate. A pair of the foot pulls can be used in tandem to provide a door stop and a means to hold a door in the open position against a wall. The design can also include actuators that can release a latch on the door. The actuators include mechanical linkages to the door handle. The actuators can also be electronic with wired or wireless connection to the latch on the door and can further be used to signal and actuate any electronic device such as a light or alarm system. The door pull can also include a mechanical cable or a hydraulic connection to actuate the door latch.

An automatic hatch assembly for bulk material containers includes a hatch cover which covers a fill opening of the container, and may be retrofitted to existing containers equipped with a conventional hatch cover. A drive unit is operable to open and close the hatch cover, and a locking assembly actuates an extendable lock member. Optionally, a pneumatic seal is provided within the cover for sealing the container from the outside environment. The locking assembly is adapted to resist opening forces applied to the cover, such as when the container is pressurized, and a sequencing controller may be provided to facilitate automated operation of the opening/closing, locking/unlocking, and/or sealing/unsealing of the hatch cover.
