Abstract: Device, systems, and methods for secure attachment and alignment of modular building units. The system includes one or more lock brackets on a first modular building unit and one or more receiver brackets on a second modular building unit. The lock brackets include a lock bracket protrusion. The lock bracket protrusion includes a locking tab having a locking tab profile including an aligning portion and a locking portion. The receiver brackets include an alignment hole. The lock bracket protrusion is inserted into the alignment hole as the second modular building unit is lowered onto the first modular building unit. The receiver brackets slide vertically and laterally along the aligning portion and the locking portion as the lock bracket protrusion is inserted into the alignment hole. The locking portion prevents vertical movement of the second modular building unit without a corresponding lateral movement.

Abstract: A walking assembly for a machine includes a walking shoe and a driving assembly including a walking frame, a driving member, and a linkage member pivotally coupled to the driving member and the walking shoe. The walking assembly also includes a sliding assembly coupled to the walking shoe and the walking frame. The sliding assembly includes a support structure adapted to be received within the walking shoe and sliding assembly plate member mounted on the support structure. The sliding assembly further includes a pair of roller chains adapted to roll on a contact surface of the plate member. The sliding assembly includes a sliding shoe adapted to be coupled with the walking frame that is in rolling contact with the pair of roller chains. The sliding assembly also includes a guiding assembly to retain the sliding shoe in rolling contact with the pair of roller chains.

Abstract: A device for propelling confetti or theatrical snow comprising two compartments. One compartment houses a vacuum device having an intake in communication with the other compartment and an exhaust in communication with the exterior of the device. The second compartment holds the confetti or theatrical snow. Only material which is able to be airborne is able to enter the vacuum device and be expelled through the vacuum device. Confetti can be reintroduced into the second compartment without fear of foreign objects mixed with the confetti becoming dangerous projectiles.

Abstract: A high proportion of inexpensive materials are utilized to provide a low-cost heating element in panel form having a resistivity of 10.sup.-.sup.3 to 10.sup.3 ohm-centimeters which may be operated in the ambient atmosphere as or in a wall, ceiling or floor of a heating or warming oven or a room of a human residence and which may be contacted by humans without receiving an electric shock or thermal burn.The composition comprises iron particles or iron filings and inexpensive material such as bottle glass or such waste material as glass from re-cycled bottles.
