Abstract: Abstract A method of flue-gas clearing comprising the separation of water-soluble substances from flue gases containing water vapour. The invention is characterized in that the flue gases are caused to be cooled by direct contact between flue gas and atomized water in two or more separ-ation steps, where in a separation step (2) subsequent in the flow direction of the flue gases the flue gases are cooled by atomized water to a temperature, at which the water in the flue gases is condensed out, which water is collected and thereafter both recirculated for utilization in said subsequent separation step (2) and introduced into a separation step (1) prior in the flow direction of the flue gases. In said prior separat-ion step the water is atomized and meets uncleaned flue gases, the water-soluble and potentially water-soluble substances of which thereby are solved in the atomized water. The water thus impurified is collected for further treatment.            The Figure is to be published.

Abstract: WRAPAROUND CLOSURE                         ABSTRACT      A wraparound closure with closure means which can be easily re-opened, such as a zipper or Velcro-type closure, provides environmental protection for splices or branch-offs in elongate substrates, such as communictions or other cables, which closure has the advantage that it can be opened and re-closed easily and quickly.  The end portions of the closure are sealed around the cable substrate with a sealing material having a cone penetration value of 100 to 350 (10-1mm) and an ultimate elongation of at least 200%. The wraparound may include a retaining means, such as a resilient plastic ring, which may be positioned to hold the wraparound closure away from the cable substrate when the closure is opened and work is being performed on the cable and may be positioned around the cable to provide support for the wraparound closure when it is in the closed position.  The sealing material is attached to the inside of the end portions of the wraparound with a neoprene rubber adhesive to assure that the sealing material adheres to the wraparound and releases from the cable when the wraparound is removed from the cable substrate.  The sealing material is also pre-formed into an appropriate shape for sealing between cables in a branch off configuration.

Abstract: Abstract of the Disclosure A device for erecting a folding carton and for holding the folding carton. The device includes a table formed of an elongated input segment and an elongated output segment. The segments are hinged together tandemwise. An anchor support member supports an input end of the input segment. An output support underlies an output end portion of the output segment. The anchor support member moves between a lowered position in which the segments of the table form a V-shape and a raised position in which the gegments of the table are subgtantially horizontally aligned. Lower end flap of the carton engage the segments when in lowered position to partially fold the lower end elaps. The lower end flaps are further folded when the segments are advanced from the lowered position to the raised position. Side flap folding mernbers are hingedly mounted on opposite sides of the table. The side llap folding mernbers swing between a lowered position free of the table segments and a raised position underlying and supporting the lower side flaps in closed position. A pusher member slides the carton with folded lower naps off the output end of the output segment to remove the carton from the table segments.                Background of the Invention This invention relates to a machine for erecting a folding carton.

Granted: 1990-09-18
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for cooling a hot product gas has a tubular zone through which the product gas is passed.  The product gas contains particles which are tacky on entering the tubular zone, but lose their tackiness through cooling in the zone.  Within the zone, a cooling gas flow forms a gas barrier which prevents contact between the product gas or the tacky particles contained therein and the walls of the tubular zone.  An annular insert, provided in the tubular zone, forms a gap through which a cooling gas is blown in counter flow to the product gas.  At the end of the insert, the cooling gas is deflected by the product gas and flows back into the insert in the same direction as the product gas to form a gas barrier over the insert wall.  The product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet of the insert.
