Latest Patents

Among his latest patents is a "Releasable coupling for air carrying tubes." This invention features an improved coupling design that includes a socket with at least four stepped bores. Within the first bore, a compression means, such as a collar, is positioned with an inner surface inclined to the axis of the bore. A collet is mounted within this compression means, allowing for inward movement that causes the jaws of the collet to close securely. Additionally, the coupling incorporates a tube support located within the second bore and multiple sealing means within the third bore, ensuring a reliable connection.

Another significant patent is the "Box intended for passing pressurized fluids through masonry work." This invention provides a box designed for the passage of pressurized liquids through thin masonry walls, particularly in dividing walls. The box is securely attached to a plastic sheath embedded in the masonry, allowing for the installation of plastic pipes for pressurized liquids. The design includes a large opening covered by a lid that facilitates maintenance and ensures a secure connection for the
