Abstract: A gate hinge pin and strap assembly for attachment to a wooden post for supporting a gate including a J-bolt or threaded L-bolt with a metal strap affixed to the bolt between the threads and cylindrical neck portion. A bendable metal strap extends on each side of the J-bolt or threaded L-bolt. The L-shaped rod is threaded into the post until the metal strap contacts the post. Then each bolt of the metal bracket is bent around the post and screws or lag bolts are threaded through the holes and into the post to help secure the hinge to the post and to provide added support for the gate.

Abstract: A self-locking gate assembly having a gate with a first hollow member and a second hollow member connected by a vertical support. A locking assembly, associated with the first hollow member is operatively connected to an upper mounting assembly adapted to open and automatically close the gate based upon activation and deactivation of the locking assembly.

Abstract: A pillar assembly has a first side member, a second side member for connecting to the first side member, a third side member having a first side channel, a second side channel, and an access opening, the third side member for connecting to the second side member, and a fourth side member having an adjustment opening, the fourth side member for connecting to the first side member and the third side member. A pillar assembly having a reinforcing member is also disclosed.

Abstract: The invention generally relates to ventilation systems and methods, and more particularly to selectively configurable climate control systems and methods for use in data centers and the like. A system includes a first structural element and a second structural element spaced apart from first structural element to define a space between the first and second structural elements. The system also includes a plurality of partitions moveable into the space between the first and second structural elements and a controller arranged to control movement of the plurality of partitions.

Abstract: A tabletop high relocateable shelter for protecting individuals from dangerous conditions such as hurricanes, tornadoes and the like, that can withstand winds of approximately 450 mph. The shelter can be attached and detached from a concrete foundation. A rectangular frame that is formed from L-shaped longitudinal members are fastened together and can be anchored to the concrete foundation by hook ended anchor bolts that have exposed threaded ends that nuts can attach thereto, or by concrete type bolts made for that purpose. Removable panels can be attached to the outside of the frame to form walls and a roof using fasteners such as screws and bolts. A door can be attached to an opening in the side of the frame, and include L-shaped members that form door braces and hinge guards that allow the door to stay in a stationary closed position. Slideable latching members can further hold the door in a locked position.

Abstract: A gate for livestock having an adjustable height. The gate has one or more hinges which allow an operator to raise or lower the gate to a number of positions. The hinges are securely attached to a rigidly mounted structure and slidably support the gate. Each hinge has a spring-loaded handle which engages one of a number of holes in the gate. The spring-loaded handle can be preset in one of two positions where a first position allows the gate to be raised but not lowered and the second position allows the gate to be lowered but not raised. Once the gate is raised or lowered to the desired position, the handle is set to the first position.

Abstract: For a vertical slide type front window of an operator's cab of construction machines, a windshield wiper assembly is mounted on a panel alongside the front window. Mounted on the part of the front window is a pin-latch unit for fixing the front window in a fully closed position. When a slide pin of the pin-latch unit is applied to lock the front window, this is detected by a detection means of a windshield control to render the wiper operative.
