Abstract: An apparatus and method for securing a structure and its roof against damage from high winds. A harness of a plurality of strap-like elements runs from or over the roof of a structure to anchors in the ground, with a coarse fabric such as shadecloth attached to and running between the strap-like elements. As the wind velocity increases, the wind pressure against the shadecloth in the area between the eaves of the roof and the ground increases, thus increasing the downward tension on the harness and further securing the roof and structure against damage.

Abstract: A magnetic novelty post card incorporating a thin sheet of magnetic material that will self-adhere to metal surfaces, and allowing an image on the front or obverse face and printed material or correspondence on the back or reverse face. A method of manufacturing a magnetic novelty post card that allows a matrix of multiple post card images to be aligned in proper registration with multiple printed paper backs, thus permitting economic and efficient use of existing post card printing plates and permitting the cutting of the multiple images into individual post cards by use of conventional die cutting or shear cutting means.

Abstract: A new and improved modular furniture design using a solid block of expanded polystyrene as a core for the furniture. This improved design combines the structural rigidity of a solid core with the light weight of plastic foam construction.

Abstract: This invention is in the field of underwater ultrasonic communications systems, more particularly, underwater acoustic homing devices suitable for diver direction finding. This invention utilizes a single omnidirectional sound source and a simple receiver, located in close proximity to a scuba diver's torso and equipment. The acoustic discontinuity of the diver's torso and equipment provides the required directional sensitivity, thus allowing the device to incorporate the desirable characteristics of flexibility in range in combination with a simple receiver housing.
