Title: Process and reactor for producing carbon black and carbon black
Inventor: GRAVLEY MARK LEE
IPC: C09C1/50
Filed: 1984-09-12
Abstract: A new reactor for the production of carbon black, a new method for the production of carbon black, and a new carbon black are disclosed. The carbon blacks are characterized by a surface area preferably in the range of 70 to 150 m<2>/g and "G" values of either less than 1.20 or greater than 1.85, corresponding to very narrow or very broad aggregate size distributions, respectively. The reactor is preferably for axial flow of combustion gases and is characterized by serial arrangement of a cylindrical combustion zone, a frustoconical converging zone, a throat, an abrupt diverging zone and a cylindrical pyrolysis zone. In certain apsects of the invention, the combustion gases are formed by combusting low BTU fuel and forcing these gases through the throat at a velocity approaching Mach 1. In one method of carbon black production, the feedstock is introduced into the converging zone. In another method, it is introduced as a spray. In other methods, the feedstock is introduced with upstream or downstream velocity components.

Title: Process of reducing nonferrous metal oxides in slags
Inventor: DEININGER LUTZ
IPC: C22B5/10
Filed: 1992-03-16
Abstract: In the reduction of liquid slags or molten salts which contain nonferrous metal oxides and are disposed over a liquid metal layer consisting of the corresponding nonferrous metal oxides and are disposed over a liquid metal layer consisting of the corresponding nonferrous metal, carbonaceous reducing agents and oxygen-containing gas are injected through nozzles into the metal layer.

Title: Method and device for the surface treatment of a metallic product in a reactive solution, in particular for the pickling or galvanizing of hot-rolled sheets
Inventor: NOGUES MICHEL
IPC: C23G1/02
Filed: 1992-04-03
Abstract: Pickling or galvanising process according to which high-frequency vibrations are imparted to the sheet metal (1) travelling through an acid-filled trough; the device comprises at least one pair of electromagnets (2,3) arranged facing each other on both sides of the sheet metal (1), which are supplied with currents of the same frequency and each exerting a periodical attraction force on the sheet metal (1), the forces exerted by each electromagnet (2,3) being offset by  pi /2, with the result that the sheet metal (1) vibrates at a frequency which is twice that of the supply current. The vibratory power injected into the sheet metal is greater than the cavitation threshold of the reactive solution in the vicinity of the sheet metal, with the result that this cavitation and the vibrations imparted to the sheet produce fissures in the layer of scale and make it easier to attack with acid, which considerably shortens the time needed for pickling the sheet metal. <IMAGE>

Title: Synchronised electronic identification system
Inventor: MARSH MICHAEL JOHN CAMILLE
IPC: G06K19/00
Filed: 1993-08-26
Abstract: The invention relates to an identification system comprising an interrogator and a plurality of transponders. The interrogator includes transmitter means (30) for transmitting an interrogation signal to the transponder, receiver means (10) for receiving a response signal from the transponder, and processor means (18) for identifying the transponder from data in the response signal. Clock extraction means (12, 20, 22, 24, 26) are further provided for extracting a transponder clock signal from the response signal which is used to synchronise the modification of the interrogation signal with the response signal from the transponder. Each transponder comprises receiver means (110, 116) for receiving the interrogation signal, a transponder clock generator (114), a code generator (112), transmitter means (110), and a modulator (118) connected to the code generator, so that on receipt of the interrogation signal the transponder transmits a response signal containing data which identifies the transponder. The interrogator is adapted to detect successful reception of a response signal from any transponder, to derive a synchronisation signal from the response signal of that transponder, and to modify the interrogation signal synchronously with the response signal to indicate successful reception of the response signal. Each transponder further includes means (116) responsive to a respective modification of the interrogation signal to cease transmission of its response signal. <IMAGE>

Date Mar. 27, 1997A wrapping apparatus is provided including a shuttle for orbital movement around an object to be wrapped, the shuttle carrying a feed roll from which a web of plastic film is drawn to wrap the object, the shuttle including a pre-stretching mechanism including: a braking roller mounted on the shuttle for rotation about an axis that is fixed relative to the shuttle; a stretching roller mounted on the shuttle for rotation about an axis which is fixed relative to the shuttle, parallel to the braking roller axis and spaced therefrom, the web being drawn directly from the feed roll around the stretching roller; drive transmission means connecting the rollers such that the surface speed of the stretching roller exceeds that of the braking roller; mandrel means for the rotational support of a feed roll of stretch wrap film mounted on the shuttle by guide means allowing the mandrel to move freely towards the braking roller under the influence of tension in a web of film drawn directly from the feed roll and passing around the stretching roller; and supplementary loading means acting independently of the web tension to supplement the effect of the web tension in urging the feed roll towards the braking roller to maintain braking contact therebetween. A method of wrapping at least part of an object in plastic film is provided including: loading a shuttle with a feed roll of the film, attaching an end of the film to the object; causing the shuttle to orbit at least part of the object; and pre-stretching the film as it is drawn from the feed roll by the relative movement between the object and the shuttle prior to its application to the object; wherein the feed roll is free to move bodily into contact with a braking roller under the effect of tension in the film departing from the feed roll and the step of pre-stretching the film is effected by of drawing the film directly from the feed roll around the stretching roller connected to the braking roller by drive transmission means ensuring that the surface speed of the stretching roller is greater than that of the braking roller, and augmenting the effect of the tension in the film in maintaining contact between the feed roll and the braking roller and having a value that is not dependent on the film tension.
