Title: Process for recovering metals from iron oxide bearing masses.
Inventor: DIGHE SHYAM V
IPC: C21B13/00
Filed: 1997-10-30
Abstract: A process for recovering iron from an iron oxide bearing mass. The process includes forming a bed (27) of lump coke (28) in a vertical shaft furnace (11), feeding the iron oxide bearing mass and scrap metal onto the bed (27) of lump coke (28) and combusting the coke (28) in the coke bed (27) while injecting a plasma gas having a temperature greater than about 5,000 degree F into the coke bed to form a reaction zone (33) within the coke bed (27) having a temperature in excess of 4,000 degree F. The iron oxide bearing mass and scrap metal fed onto the bed (27) of lump coke (28) is molten to form a molten phase containing molten iron oxide and molten scrap metal. The molten phase flows into the reaction zone and a film is formed on the lump coke within the reaction zone, the iron oxide in the film being reduced by carbon from the coke to form molten iron (22) in a solid/liquid reduction. The molten iron (22) is discharged from the furnace (11).

Patent MX-9804786-A (MX)
Title: Network management system.
Inventor: MISHRA RICHARD
IPC: H04Q3/00
Filed: 1998-06-15
Abstract: In order to satisfy a request for a connection path having a specified capacity between two specified terminations of a telecommunications network (91), a store (90) of routings and available capacities is searched to identify a connection path to satisfy the request; and if no connection path with adequate capacity is present in the store (90), a model (96) of the network is tested to identify suitable connection paths between the requested terminations, which are then added to the store (90), and allocated so as to satisfy the request. The search for suitable connection paths can take into account the hierarchical structure of the network (91) to identify suitable links to build up a path step by step. In a preferred arrangement the path is built up from each terminal point, at each stage using the link in the network which will bring the resulting ends of the two partial paths closest together, utilising, as a measure, a distance weighted according to the hierarchical level of the link.

Title: Process for the preparation of nicotinic acid.
Inventor: RODERICK JOHN CHUCK
IPC: A23L33/00
Filed: 1998-11-24
Abstract: Nicotinic acid is produced from aqueous solutions of ammonium nicotinate by spray-drying. The nicotinic acid can be freed from residual ammonium nicotinate by a thermal post-treatment in a fluidized bed or under reduced pressure. The process is suitable in particular for the work-up of the reaction mixture produced in the oxidation of 3-methylpyridine with atmospheric oxygen, with the ammonia and, if appropriate, the water, being able to be recycled. Nicotinic acid ("vitamin PP") is an important additive to foodstuffs and feedstuffs.

Patent NL-7811733-A (NL)
Title: Pipe coupling with wedging contractible ring - is disengaged by moving pipes manually inward and inserting thin half circular sleeve tool
IPC: F16L37/00
Filed: 1978-11-30
Abstract: Annular grooves inwardly from the ends of the coupling define circumferentially tapered channels in which contractible rings are disposed and arranged. Forces tending to separate the pipes and the couplings will move the contractible rings axially along the tapered surface of the channels in the coupling into locking engagement with grooves around the pipe sections. Moving the pipe sections inwardly of the opposite ends of the coupling and inserting tools between the pipe sections and the coupling engaging the contractible rings in the areas of the circumferentially tapered channels causes the contractible rings to be expanded therein sufficiently to permit the pipe sections to be withdrawn from the coupling.

Title: Selection procedure for damaged plastics crates - utilising AC measurement at different frequencies for different times to ascertain depreciation in dielectric constant
IPC: G01N27/24
Filed: 1980-06-27
Abstract: Crates on a transport unit are subjected to one or more dielectric constant measurement tests at one or more places using an A.C. voltage between 1 and 800 Hz,and pref. between 15 and 200 Hz. Under the influence of ultraviolet light, crates made of high density polyethylene show changes in the dielectric constant and this may be used as a measure of quality. In some instances, measurement may be made on each of the four side walls of the crate. The measured values of the dielectric constant loss factor, related to a new crate, and related to predetermined threshold values, are submitted to a process control computer which stimulates a rejection mechanism when the data indicate this to be necessary.
Patent NL-8005935-A (NL)
IPC: B05D1/00
Filed: 1980-10-29
Abstract: A transferable enamel sheet and the process for producing it is disclosed, which consists of a carrier film, a release layer applied thereon, a paint or enamel layer and an adhesive layer whereby a neutralization layer of wax-type consistency, preferably carnuaba wax is applied to the release layer which is of the dimethyl-siloxane type (silicone). It is possible to preform two types of transferable enamel sheets. One of them is characterized by the adhesive layer between the neutralization layer and the paint or enamel layer. In this case the enamel paint itself is used as a removal coating, which can immediately be adhered to the surface to be touched up or painted. The other type is characterized by a buffer layer, preferably acrylic resin coated on the neutralization layer and by sharp defined enamel-characters being printed on the buffer layer with an adhesive layer on the outer side to transfer the characters to any surface.
Patent NL-8501956-A (NL)
IPC: G06T5/00
Filed: 1985-07-09
Abstract: A camera 1 picks up images Gi(x, y) (i = ordinal number of the image) in a certain rhythm of a quasi-stationary object present in a noisy environment. Each of these images is converted by the camera 1 itself into an image signal gi(t). These image signals are processed in a processing device (2, 3, 4) which supplies an output image signal hi(t) as a result of each image signal applied thereto, which output image signal is converted into an image in a monitor 5. 
<??>Due to the noisy environment in which the object is present, the images Gi(x, y) consist of an ideal image H(x, y) and a noise image Ni(x, y), which noise image is in principle also present in the image supplied by the monitor 5. In order to eliminate this noise image as much as possible the processing device comprises an image enhancement circuit 3 which is provided with an accumulator circuit 33 and a weighting circuit 35. The weighting circuit 35 receives a difference signal indicating the difference between the actual image signal g/< ANd >i(n) and the output signal hi(n) of the accumulator circuit. In this weighting circuit 35 this difference signal is multiplied by a weighting factor k(i) which is dependent on the ordinal number i of the actual image signal g/< ANd >1(n). For example, k(i) = 1/i.
