Title: Method for premixed combustion of a liquid fuel
Inventor: KELLER JAKOB
IPC: F23D11/02
Filed: 1990-12-13
Abstract: ABSTRACT OF THE DISCLOSURE     In a premixed type of combustion of a liquid fuel at high pressure, the injection of the fuel (4c, 4d) and  its  evaporation with  a  gaseous  medium  (5)  is undertaken, in order to prevent premature ignition of the liquid/gaseous mixture in the burner itself, at a location where the droplets of the fuel from the fuel nozzles (4a, 4b) are screened from the flame radiation from the flame front of the burner.   As soon as the fuel (4c, 4d) is pre-evaporated, i.e. leaves the duct (7a, 7b) via the inlet slot (1d, 2d) in the direction of the internal space (3) of the burner as a mixture (6), it absorbs practically no flame radiation.

Abstract: ABSTRACT OF THE DISCLOSURE      A portable animal waste device for use in conjunction with a standard household commode is described.  A support structure mount-ing a pivoting platform and emplaced over the toilet bowl, is con-nected to the toilet's flush mechanism.

IPC: B30B9/30
Filed: 1991-02-06
Abstract: A baling press provided with a pressing box, a feed chute connected with the pressing box via a passage, at least two prepress valves. The prepress valves are each pivotable about a pivotal axis, provided with a flat wall which in closed position closes off the passage from the feed chute to the pressing box and in opened position is disposed in the wall of the feed chute, and with a surface substantially curved about the corresponding pivotal axis, which surface in closed position bounds the feed chute in axial direction. One of the prepress valves is provided with a connecting surface which in the closed position is curved about a pivotal axis of one other of the prepress valves. In that closed position, the connecting surface is disposed at a distance from the curved surface of said other prepress valve which is at most minor and substantially constant. The invention provides a possibility of avoiding material to be pressed getting stuck between the prepress valves when the prepress valves are being closed.

Title: Method and apparatus for burning of pollutants contained in a carrier flow
Inventor: OBERMULLER HERBERT
IPC: F23G7/06
Filed: 1991-03-08
Abstract: TITLE OF THE INVENTION     METHOD AND APPARATUS FOR BURNING OF POLLUTANTS CONTAINED IN A CARRIER FLOW            ABSTRACT OF THE DISCLOSURE     In a method and apparatus for cleaning a gas flow that carries oxidizable pollutants in varying concentrations, the temperature within the combustion apparatus is main-tained substantially constant by admixing controllable proportions of the gas to be cleaned and/or fresh air to the combustion flow.  However, admixing prior to introduc-ing the gas to be cleaned into the combustion flow is avoided by performing the admixing at a location near the exit end of a flue gas mixing pipe.  This mixing location permits maintaining the combustion chamber temperature con-stant or at its rated level while simultaneously keeping the temperature of the flow control device at acceptable levels.  The flue gas mixing pipe is arranged downstream and coaxially with a burner so that the admixing takes place after the combustion or carrier flow has already passed the burner at the entrance to the combustion chamber.

Title: Method and apparatus for modifying fibers and fabric by fatiguing
Inventor: DISCHLER LOUIS
IPC: D06C17/04
Filed: 1991-10-11
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus is provided for modifying fiber or fabric by fatiguing that creates at least one of the following characteristics including: axially aligned cracks, physical change created by the bending and compression of the fiber along the fiber's longitudinal axis taking the form of kink bands, enlarged segregated fibular tangles or enlarged nodes.  Fatiguing is defined as repeated stress on fiber by high velocity impact that bends the fiber and compresses it in a direction parallel to the fiber's longitudinal axis.  Fatiguing results in softer hand and/or improved dyeability in some fabrics, including but not limited to liquid crystal fabrics and cellulosic vegetable fabrics.  The application of one or more gas jets directed away from the interior curved surface of a cylinder, generating a vortex which rapidly and repeatedly cycles the substrate at low tension past the gas jets.  The rapid vibrations generated in the substrate by the jets serve to break apart fiber to fiber bonds caused by finish and loosen up the structure of the yarns and that of the substrate.          This creates a desired aged appearance as well as a very soft texture.

Title: Process of and apparatus for preparing dinitrogen pentoxide
Inventor: BAGG GREVILLE E G
IPC: B01J19/24
Filed: 1991-07-25
Abstract: Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas.  N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert or-ganic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporisation of the solvent, so limiting in-creases in reaction temperature and suppressing the dissociation of the N2O5.  In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recirculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.
