Title: Methods and apparatus for providing a broker application server.
Inventor: BOWKER DUANE OLIVER
IPC: H04L9/14
Filed: 1998-04-13
Abstract: A broker application server for facilitating communication between one or more senders and one or more receivers over a digital packet network. Each receiver receives data in a preferred format. Information identifying the preferred data format of each receiver is stored in a database in the broker application server. The broker application server receives digital packets addressed to a receiver. It extracts data and address information from the packet and optionally decrypts the data. It examines the data to identify the data format. If the data is in the preferred format of the addressed receiver, the broker application server optionally encrypts the data, formats it into a packet, and transmits it to the appropriate receiver. If the data is not in the preferred format of the addressed receiver, the data is transcoded into a common or raw data format and further transcoded into the preferred data format of the addressed receiver before being optionally encrypted, formatted into a digital packet, and transmitted to the addressed receiver.

Title: Method for preparing melamine.
Inventor: TJAY TJIEN TJIOE
IPC: C07D251/60
Filed: 1998-05-15
Abstract: Method for preparing melamine from urea via a high-pressure process in which solid melamine is obtained by transferring the melamine melt coming from the reactor to a vessel where the melamine melt is cooled with an evaporating cooling medium. The melamine melt comes from the melamine reactor at a temperature between the melting point of melamine and 450 degree C and is sprayed into a cooling vessel, via spraying means, and cooled by means of an evaporating cooling medium to form melamine powder. The cooling vessel has an ammonia environment with an increased ammonia pressure. The melamine melt is thereby converted into melamine powder having a temperature of between 200 degree C and the solidification point of melamine. The melamine powder is then cooled to a temperature below 200 degree C with the powder mechanically agitated and being cooled directly or indirectly, after which the ammonia pressure is released and, if necessary, the melamine powder is cooled further.

Abstract: Tung oil-based modified amine curing agent and preparation method and use thereof A tung oil-based modified amine curing agent and a preparation method and use thereof. Methyl 5 eleostearate, phenol and a catalyst are added into a reaction vessel, in a state of continuously introducing nitrogen the mixture is stirred and heated for a reaction, the reaction is cooled, washed and allowed to stand, and an upper brown viscous liquid is dried with anhydrous sodium sulfate to obtain a tung oil-derived phenolic adduct; the tung oil-derived phenolic adduct and polyamine are added into a reaction vessel, and mixed and stirred uniformly, an aldehyde is dropwise added, and 10 after the dropwise addition is completed, the mixture is heated for a reaction, and then reduced-pressure distillation is performed to remove the generated water, to obtain a tung oil-based lVlannich base curing agent; and in a stirring state, polyamine is further dropwise added to the tung oil-based lVlannich base curing agent, the mixture is heated and refluxed and then subjected to an amidation reaction, and when no water or free amine is distilled out, the heating is 15 stopped, and the remainder is cooled to room temperature to obtain a dark brown viscous tung oil-based modified amine curing agent. The active cross-linking points of a curing reaction of the tung oil-based modified amine curing agent are distributed more extensively and uniformly, and a better balance can be achieved between the hardness and flexibility of a coating, so that the coating is tougher.

Title: Underwater dredger digger wheel - has pump mounted close to intake for maximum pressure difference
IPC: E02F3/92
Filed: 1976-10-20
Abstract: The underwater dredger digger wheel has the pump mounted very close to suction intake, giving max. pressure difference between them. The force of gravity on the material acts in the same direction as the suction current, this being effected by buckets on the wheel extended by guards, extending as far as the suction pipe and open at the bottom. The material does not start to be sucked in simultaneously with excavation, but only when the bucket guard is at from 35 to 50 deg. above the horizontal, and the wheel roates in a plane at right angles to the dredger ladder centre line. The pump suction pipe has no bends, being taken through the wheel drive shaft and the hollow reduction gear output shaft, Qand the entire unit is accommodated on a prefab. mounting. A parallelogram linkage holds the wheel in the desired position for all dredging depths, and the entire unit hinges on the ladder. Within limits, the wheel can be brought into any desired position and held there for all depths.

Title: (Thio)acyl-pyrazole derivs. used as soil nitrification inhibitors - e.g. in soil treated with nitrogen-contg. fertiliser
IPC: C05G3/90
Filed: 1977-10-24
Abstract: New agents for inhibiting or regulating nitrification of ammonium nitrogen in culture media contain as active ingredient >=1-acyl-pyrazole of formula (I). In (I), R' and R3 are H, halogen, opt. substd. alkyl or aryl, and R2 is H, halogen, alkyl or NO2. When R' and/or R3 is/are H or alkyl, then R4 is opt. substd. alkyl, alkenyl, aryl, opt. substd. aryloxy, alkylmercapto or arylamino and X is O or S. When R' and/or R3 is/are halogen or aryl, then R4 is opt. substd. alkyl, alkenyl, aryl, opt. substd. alkoxy, aryloxy, alkylmercapto, arylmercapto, or amino opt. substd. by alkyl and/or aryl, and X is O or S. The alkyl and aryl residues may be substd. by halogen, CN, COOH, alkoxycarbonyl, NO2, OH, alkoxy, aryloxy, amino (in turn opt. substd. by alkyl and/or aryl, or acyl), alkyl or aryl. Used to prevent nitrification of ammonium nitrogen (esp. that added in fertilisers) in order to minimise loss of nitrogen by leaching out of the more soluble nitrate nitrogen formed by the nitrification process. This gives improved utilisation of nitrogen added in fertillisers and reduces nitrate pollution of ground waters. (I) have adequate water-solubility and are non-volatile. Their stability ensures prolonged action. Activity is evident with low concens. of (I).

IPC: C01F11/46
Filed: 1979-12-15
Abstract: Prodn. of H3PO4 and CaSO4.1/2H2O is carried out by (a) reacting a phosphate ore with H2SO4 under conditions such that the CaSO4 pptes as hemihydrate; (b) separating the hemihydrate and washing it under conditions such that the hemihydrate is not converted to dihydrate, while cpds. which migh inhibit the conversion of hemihydrate to dihydrate are removed by decompsn. and/or dissolution, (c) removing free moisture from the hemihydrate, (d) converting the hemihydrate to dihydrate by direct cooling, and (e) converting the dihydrate to hemihydrate in known manner. The process permits simultaneous prodn. of conc. aq. H3PO4 (e.g. with a P2O5 content of 40-54 wt.%) and high-purity CaSO4,1/2H2O, which is a more useful by-prod. than CaSO4.2H2O.

Title: Air distributing throttle for ventilation system - has cleaning jets supplied by air bled from main ventilation air stream which is redirected back into main-stream by tube nest cover
IPC: F24F13/00
Filed: 1979-12-18
Abstract: A nest of fine tubes (11) is held in a cylindrical case (14) which is placed within a ventilation duct (10). The resistance of the tubes distributes the air evenly over the duct. Part of the air (52) flows through a wider central tube (24) forming part of a rotating cover. It is deflected by the bottom (32) of the cover and flows up the tubes to clean them. The top of the cover (30) redirects the air to rejoin the main stream by a further central tube. The cover lies over part only of the tube nest. The reaction of the air causes it to rotate continuously over the nest of tubes.
