Title: Method and Apparatus for Continuously Hot Rolling of Ferrous Long Products
Inventor: SHORE TERENCE M
IPC: B21B1/10
Filed: 1992-04-21
Abstract: A method and apparatus for continuously hot rolling ferrous long products which employs a "post finishing" block of roll stands downstream from the finishing stands of the mill.  Water boxes or other like cooling devices are preferably interposed between the last mill finishing stand and the postfinishing block.  The post finishing block includes at least two reduction stands followed by at least two sizing stands.  The reduction stands have an oval-round pass sequence, and the sizing stands have a round-round pass sequence.  Clutches or other equivalent means are employed in the drive train to permit changes to be made between the interstand drive speed ratios of at least the reduction stands, and also between some or all of the remaining sizing stands.   A fixed rolling schedule is provided for all roll stands in advance of the finishing stands.  Thus, the finishing group is supplied with a first  process  section  having  a  substantially  constant  cross sectional area and configuration.   The first process section is passed through the finishing group and rolling occurs in either none, some, or all of the finishing roll stands, depending on the size of the desired end product.   The product then continues through water cooling boxes to the post finishing block as a second process section.  The interstand drive speed ratios of the roll stands in the post finishing block are appropriately adjusted to accommodate rolling of the second process section.   The total reductions affected in the initial reduction stands of the post finishing block are well above 14%, thereby producing an increased energy level in the product sufficient to create a substantially uniform distribution of fine grains.  Typically, such total initial reductions will be on the order of about 20-50%.   Significantly lighter reductions on the order of 2-15% are taken in the final round-round pass sequences of the post finishing block to obtain the desired close sizing tolerances in the finished product.  The time interval between the higher reductions affected in the oval-round pass sequence and the lighter reductions affected during sizing in the round-round pass sequence is such that the resulting grain size throughout the product cross section will not vary by more than 2, and in most cases by less than 1 ASTM grain size number.

Patent CA-2069221-A1 (CA)
Title: Process for salt extraction from hydrogen-sulphide scrubber solution using electrodialysis
Inventor: KENNEDY MARK W
IPC: B01D61/44
Filed: 1992-05-22
Abstract: Abstract This invention relates a method for the selective removal of alkali metal salts of sulphate (SO42) and thiosulphate (S2O32) from hydrogen sulphide (H2S) scrubber solutions of the liquid redox type using an electrodialysis system. In the process of this invention the H2S scrubber solution is directed to the diluting compartments within an electrodialysis stack while a collecting solution with a minimal initial salt content is directed to the concentrating compartments. With the application of a direct current a portion of the alkali metal salts of sulphate and thiosulphate present in the scrubber solution are transported through ion selective membranes into the collecting solution. Essentially all of the metal organic chelate reagents and carbonate ions initially present in the scrubber solution are retained in the desalted solution and can be recycled to the H2S scrubbing process. Organic fouling of the anionic membranes is avoided by maintaining the organic weight fraction of the total dissolved solids in the diluting solution less than 0.15 and preferably less than 0.05. High current efficiency is obtained at salt concentrations above 5 normal in the diluting solution by maintaining the salt concentration of the collecting solution below that in the diluting solution.

Abstract: A rotary filter for filtering water out of water containing raw material such as fish guts and muds including a screw drum having a number of filtering holes formed therein and a screw having a shaft and a spiral vane secured to the outer surface of the shaft, in which the screen drum is arranged rotatably, the screw is arranged within the screen drum rotatably relative to the screen drum, and the screen drum and the screw are rotated by means of separate driving sources independently from each other. A period of time during which the water containing raw material is remained within the screen drum can be adjusted at will in regardless of the rotation speed of the screen drum. Therefore, the screen drum can be rotated at a high speed while the raw material can be remained within the screen drum for a long time period, so that the water filtering efficiency can be increased largely.

Abstract: STEERABLE INFUSION GUIDE WIRE                 ABSTRACT OF THE DISCLOSURE   A guide wire having state-of-the-art handling characteristics for ease in positioning a variety of catheters and other devices within the cardiovascular or other body system wherein the guide wire is also suitable for infusion of small volumes of fluid.  The exceedingly small diameter guide wire has unique infusion properties. The guide wire body has at least one helical coil having a flexible non porous sheath within the lumen.  The helical coil is close wound along the majority of its length.  The distal end of the helical coil has spaced windings to permit infusion of the fluid.  The flexible nonporous sheath terminates proximal to the space wound portion.  The solid core wire, which runs the entire length of the guide wire, is located within the same lumen used for infusion.  This provides a greatly increased surface area in relation to the cross sectional area of the infusion lumen ensuring a slow but extremely constant infusion rate over a wide range of infusion pressures.

Patent CA-2076891-A1 (CA)
Inventor: BOGART FRANK J
IPC: H04Q3/545
Filed: 1992-08-26
Abstract: Any valid displayed called number may be properly visually segmented by a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the whole network numbering plan. The syntax definitions include definitions (312) of individual symbol strings and their associated display demarcations (360), if any -- such as spaces or dashes or parentheses -- or even their associated replacement strings. Display demarcations or replacement strings that are specified for individual symbol strings are administratively reprogrammable to change the specified display demarcations or replacement string. Following dialing of an individual symbol string, the symbol string is identified and it or its replacement is displayed (986) on the display (19) of the caller's telephone set (17) along with any previously-dialed symbol strings and is demarcated therefrom as specified in the definition of the symbol string. A caller thus always receives a display of any valid dialed number either properly visually segmented into its logical components or replaced by its logical meaning.

Abstract: An apparatus for inserting a staple into torn tissue such as the meniscus of the knee. The apparatus includes a pair of shafts individually movable in a longitudinal direction which are actuable from a handle mechanism. The shafts are movable sequentially so that the shafts disjunctively advance the prongs of the staple which is releasably held adjacent distal end portions of the shafts. A further embodiment of the device consists of a pair of needles detachably secured to a pair of anchoring members having a plurality of barb-like projections extending outwardly therefrom. The anchoring members are joined by a suture which connects adjacent the trailing ends of the anchoring members opposite the penetration end of the needles. The needles are engaged with the anchoring members to transmit a first pushing force applied to the needles to advance the anchoring members into the tissue, and are releasable from their engagement with the anchoring members responsive to a second pulling force applied to the needles in a direction opposite the pushing direction.
