Title: Ammonium cpd. removal from waste water - esp. biological sludge filtrate waste water, by steam stripping
Inventor: GOSSEL CHRISTIAN
IPC: C01C1/10
Filed: 1992-11-23
Granted: 1994-04-28
Abstract: In removal of ammonium-contg. cpds. from waste waters (esp. filtrate waste waters from biological sludges) by preheating and stripping with steam, (i) the waste water is pretreated by solids removal and raising to pH 11, prior to heating in a heat exchanger (28); (ii) the pretreated and heated waste water is steam stripped in a packed column (32) using steam produced in an evaporator (40) by partial evapn. of a recirculated substream of the column discharge; (iii) the major part of the heat required for stripping steam prodn. is covered by condensation of the ammonia-loaded used stripping steam which has been compressed to the requisite condensation pressure by a compressor (60); and (iv) condensation of the ammonia-loaded used stripping steam is carried out in the evaporator (40). Also claimed is appts. for carrying out the process. ADVANTAGE - Energy-efficient removal of ammonium cpds. from waste waters.

Title: Suction-extraction device for a smoothing iron
Inventor: WHITAKER BARRY
IPC: D06F75/08
Filed: 1992-12-31
Granted: 1994-10-06
Abstract: Fastened releasably to a smoothing iron (11) is a suction-extraction device which is provided with an integrated suction blower having an associated air-purifying means. The suction-extraction device possesses, on its underside, a suction port (29), via which vapours released during the ironing of textiles are sucked, together with air, into the interior of the suction-extraction device (13). Toxic substances, such as, for example, formaldehyde, which are released during ironing, are guided through the suction-extraction device, the harmful-substance filter (55) of which filters out such substances. In order to suck the vapours in as completely as possible, the suction port (29) is arranged directly adjacent to the heated sole (17) of the smoothing iron (11). <IMAGE>

Title: Cardan shaft with a closable maintenance orifice in protective tubes
Inventor: GROSE-ENTRUP HUBERT DIPL ING
IPC: A01B71/08
Filed: 1993-05-22
Granted: 1994-08-11
Abstract: The invention relates to a cardan shaft for the drive of agricultural machines. In addition to the two profiled tubes 1 displaceable one in the other and serving for the transmission of torque, there are provided two protective tubes 5, 6 which are correspondingly axially displaceable one in the other. So that the profiled tubes can be lubricated, there is provided a maintentance orifice which, in the case of a specific cardan-shaft length, is obtained by means of the coincidental positions of two orifices 11, 12 in the protective tubes 5, 6. However, in the state of non-use, the orifice 11 in the outer protective tube 6 is covered by a closing sleeve 9. When the cardan shaft is extended, after the displacement of the closing sleeve 9 for the purpose of access to the orifices, the closing sleeve 9 is automatically transferred into the closing position again by means of a cam 13. This ensures improved safety, since it is guaranteed that the orifices are always closed when the cardan shaft is in use. <IMAGE>

Title: Double stroke cylinder
Inventor: AMON HENRY
IPC: F15B15/14
Filed: 1993-06-11
Granted: 1994-10-27
Abstract: A double stroke cylinder for a punching/riveting machine has a cylinder housing 6 in which a prestroke piston 7 is arranged in a displaceable manner. The prestroke piston 7 is designed as a hollow cylinder and accommodates a working piston 10 which is driven by the prestroke piston 7 and is displaceable relative to the prestroke piston for performing its working stroke. The working piston 10, with a cylindrical body 15 connected to the cylinder housing 6 and projecting into the prestroke cylinder, defines a working chamber 19 to which a pressure medium is admitted for performing the working stroke. By the admission of pressure to the prestroke 7 and the working piston 10 independently of one another and by the support of the pressure producing the working stroke on the cylindrical body 15, high working pressures can be realised without a reaction on the prestroke piston 7. <IMAGE>

Title: Harmful gas emissions oxidn. by cool extn. and hot return to tunnel furnace
Inventor: BENZEL MARTIN DIPL ING
IPC: F27D17/00
Filed: 1994-04-08
Granted: 1995-08-10
Abstract: In a process to oxidise substances in gases within a tunnel furnace, gases flow against the charging direction through a number of zones in the furnace before they are exhausted to the atmosphere. The novelty is that part of the gases at the initial point of flow through the furnace are drawn off before a first heating zone, and are returned to the tunnel at the highest temperature point of a second zone which serves as a combustion zone. After flowing through this second zone the gas is released to the atmosphere. Gas is also drawn off at the beginning of the second zone to pass through a heat exchanger where it surrenders heat to gas drawn from the inlet of the first zone before it is fed to the point at which the maximum process temperature prevails in the tunnel furnace.

Title: System is for traffic regulation and has threshold component movable in height direction provided with upper surface and blockade device
Inventor: SCHOEREN HUBERTUS JOHANNES BER
IPC: E01F9/529
Filed: 2004-02-04
Granted: 2005-08-08
Abstract: The system is for traffic regulation (600) and has a threshold component (200) movable in height direction provided with an upper surface (201) and a blockade device (100) for selectively blocking in the height direction of the threshold component. The blockade device incorporates at least one vehicle sensor (110), located at some distance from the threshold component for detection of the presence of a vehicle. The blockade device can block the threshold component by means of a force transmission medium, such as a fluid, gas or electro-magnetic force field. If the sensor detects the presence of a vehicle it emits a corresponding signal to a regulating unit (130), which after a specific time interval activates electro-magnets (120). As a result, a flange (202) on the threshold component is drawn towards the electro-magnets, so that a position extending above the road surface (601) is fixed or blocked.

Abstract: FIELD: fuel combustion systems. SUBSTANCE: highly viscous liquid fuel (mazut) and fuel gas (gaseous products of oil refining) are admitted to lower part of saturator under a pressure of 0.3-0.6 MPa. Part of gases (mostly high-density hydrocarbons) is dissolved in the liquid fuel, whereas light fractions are retained in fuel mixture in the form of fine bubbles. When the thus obtained fuel mixture (emulsion) and air are injected to burner, gases are expanded due to a sudden pressure differential to vigorously break liquid fuel into fine droplets. The air-fuel mixture is ignited in high-temperature space of the furnace at a distance from the burner to fully burn downstream of the flow. EFFECT: enhanced efficiency of combustion. 1 tbl
