Title: Sepn. of solid materials from suspensions in liquids - using vessel with archimedean screw, bucket-wheel and vibratory trough
IPC: B01D35/20
Filed: 1975-06-25
Abstract: The plant incorporates a vessel, an Archimedean screw, a bucket-wheel and an inclined vibrating trough. The suspension flows along the vessel and the screw rotates in it so as to drive the solids upstream into the path of the bucket-wheel.

Title: Force fit driving-in tool esp. for bolt - generates electromagnetically controlled mechanical stress wave which acts on bolt end
Inventor: LEFTHERIS BASIL P
IPC: B25C1/06
Filed: 1975-09-15
Abstract: The bolt-driving tool provides a force-fit for the bolt in a hole whose diameter is smaller than that of the bolt. The tool generates electromagnetically a controlled mechanical stress wave which acts on the bolt end. The mechanical stress wave has a high particle velocity and is controlled by a conditioning unit which regulates the intensity and duration of the high-speed stress wave in such a way that during a considerable proportion of the wave's duration a high stress level is maintained. The conditioned stress wave brings about a contraction of the bolt at right angles to the direction of propagation of the wave. The wave is reflected from the far end of the bolt in order to bestow a high speed to that end and enable it to overcome any frictional forces between the bolt and the walls of the reception opening.
