Title: Plasma-heated chemical reactor - for finely dispersed solids, using plasma temps., of 3000-5000 deg. K
IPC: B01J15/00
Filed: 1974-06-24
Abstract: A plasma-heated chemical reactor comprises a vertical chamber, with an upper inlet for dispersed materials (fine powders) and has a ring of plasmatrons arranged around the periphery of the lower part of the vessel with their axes perpendicular to the longitudinal axis of the vessel. The gaseous reaction products may be removed through connections in the upper part of the reactor or through connections in a bunker under the reactor in which the treated powder collects. Used for treatment of powders with very high melting pts. and low thermal conductivities, e.g. spheroidising or surface coating. The arrangement gives freedom from blockage of the plasmatron nozzles by molten material.

Title: Mechanical compactor for stone floor tiles - uses eccentric ball deck to transmit vertical vibrations only
IPC: E04F21/22
Filed: 1974-06-26
Abstract: A compactor/rammer for stone tiled floors, avoiding the danger of the tiles vibrating horizontally and disturbing the grout, has a base (6) on which is mounted the eccentric out-of-balance motor and a solid plate (8) with steel balls (9) underneath. A second plate (10) underneath and parallel to the first one to which it is rigidly fixed locates the balls. This second plate is predrilled with a set of holes and spaced from the first plate which is less than the diameter of the balls so that a portion of each ball protrudes below the lower of the second plate. Thus, when in use, only vertical vibration is transmitted to the floor. The only point of contact between the machine and the floor surface is on the balls and any horizontal vibration is absorbed by the balls as they can move a small distance laterally the holes through which they protrude being slightly larger than required.
