Title: Steckel mill coiler furnace incorporating heated pinch rolls
Inventor: SMITH OLAN R
IPC: B21B1/34
Filed: 1995-06-27
Abstract: For economy of operation, as much as possible of the total length of a steel strip being rolled by a Steckel mill (11) should be maintained at an acceptable high temperature. To this end, the trailing edge of the strip is drawn into the coiler furnace (21 or 23) to the extent possible without losing driving control of the strip. This is enabled by providing within or in close proximity with the entrance/exit port (35) of the coiler furnace (21 or 23) a pair of preferably heated pinch rolls (41 or 43) that drives the trailing edge of the strip into the coiler furnace (21 or 23) as far as possible, leaving only a very short protruding portion of that trailing edge outside the coiler furnace (21 or 23). The strip may be left idle within the coiler furnace (21 or 23) for as long a time as is required to bring the temperature of the wound strip up to a target operating temperature. Then the same pair of pinch rolls in (41 or 43) or near (31 or 33) the entrance/exit port (35) of the coiler furnace (21 or 23) drives the strip out of the coiler furnace (21 or 23) toward the Steckel mill (11).

Title: Determination of characteristics of material
Inventor: ULRICHSEN BORRE BENGT
IPC: B07C5/346
Filed: 1995-08-21
Abstract: A system for automatically inspecting matter for varying composition comprises one or more detection stations (131) through which one or more streams of matter are advanced and particular materials therein are detected through their diffusely reflected IR spectra, if any, and/or through their variation of an electromagnetic field by their metallic portions, if any. A row of light sources (105) distributed across the overall width of one or more belt conveyors (104) may cause desired portions (125) of the stream to reflect light diffusely onto a part-toroidal mirror (107) extending over that overall width, whence the light is reflected, by a rotating, polygonal mirror (108) through optical filters dedicated to differing IR wavelengths, onto detectors (120) the data output of which is utilised in controlling solenoid valves operating air jet nozzles (116) which separate-out the desired portions.  Alternatively or additionally, an oscillator (137) and an antenna (138) which extends over that overall width generate an electromagnetic field through the belt (104) and sensing coils (139) sense variations therein produced by metallic portions of the stream passing through the detection station (131) and the detection data produced by the sensing coils (139) is used to control the solenoid valves operating the nozzles (116) to separate-out the metallic portions.

Title: Large bulk liquid squeeze bag
Inventor: LAFLEUR LEE
IPC: B66C1/22
Filed: 1997-04-02
Abstract: A flexible and collapsible bulk bag having an upright orientation in use with top and bottom end access openings to the exterior of the bag through which a flexible and collapsible liner is received in the bag, the liner also having top and bottom access openings through which the bulk contents are respectively entered and discharged. When the bag is expanded and filled it has a pair of spaced apart and generally conical ends formed by four triangular portions interconnected by four generally rectangular side walls, with the ends convergently tapering toward their associated access opening. The bag when empty can be collapsed into a compact, flat configuration having a pair of overlying front and rear panels with a pair of folded gusseted side panels received therebetween. A pair of laterally spaced apart U-shaped hanger straps at the top end of the bag together flank the bag and liner top openings and each comprise a two-ply front extension and a two-ply rear extension with mutually overlapped portions permanently interconnected to thereby form a four-ply thickness where these hanger strap extensions mutually overlap. A strap reinforcement saddle includes U-shaped end straps sewn over the bag hanger straps along inner edges thereof and extending down to the bag front and rear bag panels. The bag bottom end opening has four flaps, and a cooperative reinforcement girdle has a horizontal strap belt encircling the bottom end triangular portions of the bag and is affixed thereto. The girdle also has four belt loops each connected to the strap belt and extending downwardly past the lower end of the associated flap and then upwardly along the interior side of the flap back to the belt. A tie cord is strung serially through the belt loops and is operable upon tightening to draw them together to thereby close them across the bag bottom discharge opening. The bag, liner, associated fill and discharge spouts and girdle are all constructed of flexible material and are respectively compressible together. Alternatively the liner has a rigid discharge outlet spout and a protective exterior flap spans beneath the spout outlet closure to serve as an openable, flexible protective barrier for the same. When the bag is full and ready to be discharged, the bag and liner are suspended vertically by hoisting from the bag hanger straps. A pair of squeeze nip rollers may then be applied across the front and rear panels and then pulled downwardly therealong to thereby squeeze any remaining contents out the liner discharge opening. When the discharge outlets of the liner and bag are made of flexible and compressible material, the nip roller squeegee stroke continues therealong the material of these outlets to also empty any contents remaining therein.

Title: Method and apparatus for producing liquid products from air in various proportions
Inventor: SUCHDEO SHYAM RAMCHAND
IPC: F25J3/04
Filed: 1997-05-30
Abstract: A cryogenic method and apparatus using a liquefier and a two stage distillation column capable of operating in two modes, namely a first mode of operation during which only liquid nitrogen is produced and a second mode of operation during which liquid nitrogen and liquid oxygen are produced. By adjusting the time of operation in each mode, any ratio of liquid nitrogen to liquid oxygen greater than the ratio achieved during the second mode of operation can be achieved. In the first mode of operation, a condenser is used to condense the lower pressure stage gaseous nitrogen into lower pressure stage nitrogen condensate. To condense the lower pressure stage gaseous nitrogen, either at least a portion of the crude oxygen liquid from the higher pressure stage, at least a portion of the oxygen-enriched liquid from the lower pressure stage, at least a portion of the liquefied air, or mixtures thereof, are introduced to the condenser. In the second mode of operation, the top condenser is not used; instead, all of the crude oxygen liquid is introduced into the lower pressure stage, which produces a bottom liquid oxygen stream and a low pressure overhead waste stream containing nitrogen. The system includes fluid flow lines and valves for directing the flow of certain fluids, particularly the crude oxygen liquid and the oxygen-enriched liquid, during the two modes of operation.
