Abstract: A padlock includes a body with a primary channel that rotatably receives a sleeved cam. The sleeved cam contains a vending style lock with a deployable lug. The lug aligns with a window in the sleeve of the sleeved cam and extends through the window into a lug compartment in the body when locked. The cam of the sleeved cam moves locking members (e.g., balls that mate with hemispherical notches in a shackle), when the sleeved cam rotates between locked and unlocked positions. The padlock may be rekeyed by replacing the lock plug.

Abstract: A system and method for cleaning dirty water is disclosed. The systems and methods may include two heat exchangers, including a high temperature/high pressure (HT/HP) heat exchanger that receives superheated steam and hydrogen gas and a low temperature/low pressure (LT/LP) that receives steam at a reduced temperature and pressure. The LT/LP heat exchanger provides first stage heating to dirty water that is input into the system for cleansing. The LT/LP heat exchanger has a first coil and a second coil. The first coil carries the dirty water to be cleaned. The HT/HP heat exchanger provides a second stage of heating to the dirty water that is output from the LT/LP heat exchanger. A first coil of the HT/HP heat exchanger carries the superheated steam and hydrogen gas. A second coil carries the preheated dirty water that is output from the LT/LP heat exchanger.

Abstract: An anti-tampering device secures bolted components, such as a trailer coupler mounted to an adjustable channel. A nut shield provides hexagonal channels in which nuts are contained. A hasp assembly provides a locking tab. Bolts secure the nut shield and the hasp assembly to the components. A hasp shield with a notched annular flange overlays the hasp assembly, receives the tab through a slot in the area surrounded by the notched annular flange, and contains a puck lock in the area. The puck lock engages the locking tab.

Abstract: A trailer coupler includes a lock contained within a channel in a coupler body. A pin extends from the lock. The pin extends through an aperture in an end of the channel and through an aperture in a latch handle when the lock is locked. In such configuration, the pin prevents pivoting the latch handle to an open (unlocked) position. Unlocking the lock allows the lock to be moved at least partially out of the channel, which removes the pin from the aperture in the handle, allowing the handle to pivot to an open (unlocked) position.
