Abstract: An interlocking privacy fence is made up of a series of molded panels with simulated paneling and lattice in relief bounded on each lateral side by a leg. One leg has a plurality of brackets along the length thereof. The other leg has a plurality of pintles along the length thereof. Each of the brackets has an aperture therethrough for receiving a prong of a pintle. In assembly, the brackets of different panels are aligned with the pintles of other panels and the pintles are inserted through the apertures such that each leg is interlocked. The bottom of the legs are formed as a sharpened spade for insertion into the ground to fix the fence in place.

Abstract: The present invention relates to kit for a trash container utilizing injection molded plastic panels capable of being packaged and shipped in a knocked-down state and constructed into a secure container.

Abstract: The invention relates to a method for the removal of viscoelastic rubber residues from deep holes. The cleaning tool is suggested in the form of a jet of fluid droplets. The fluid is accelerated by a high-pressure pump and a narrow valve to a velocity above the speed of sound of the material to be removed. The distance between the valve and the hole to be cleaned is made greater as the valve cross-section is made smaller in relation to the cross-section of the hole to be cleaned.
