Abstract: An apparatus for marking pipes at a plurality of cutting angles comprises a marking plate of adjustable length. The marking plate comprises a plurality of apertures and a plurality indicators. Each aperture is of a different size and configured to receive a pipe of a certain diameter through the marking plate. Each aperture is defined by a first half-circle side and a second half-circle side and the distance between the first half-circle side and the second half-circle side of each aperture varies according to the adjusted length of the marking plate. Also, the distance between the first half-circle side and the second half-circle side of each aperture corresponds to an angle of a pipe received through the marking plate. Indicators specify a diameter of a pipe received through the adjustable marking plate and the angle of the pipe with respect to the adjustable marking plate.

Abstract: An apparatus for supporting an object at a window of a building comprises a first member, a second member, and a third member. The first member extends along at least a partial width of the window and abuts an interior surface of the building. The first member is configured to support the object by exerting an outward force on the interior surface of the building in response to a downward force exerted by the object. The first member also comprises at least two sections extending from the interior of the building to the exterior of the building. These sections may extend from the interior of the building to the exterior of the building about respective distal ends of the first member. The sum of the forces applied on the surfaces of the building are sufficient to secure the object to the building.

Abstract: A system for securing an air conditioning unit to a building without the need for any alteration and/or damage to the building itself. The system includes a cross bar, an air conditioning unit support, and a strut. The arrangement of the components results in the cross bar applying an outward force to an interior surface of the building and strut applying an inward force to an exterior surface of the building in response to the downward force exerted on the air conditioning unit support. The sum of the forces applied on the surfaces of the building is sufficient to secure the air conditioning unit to the building.
