Abstract: A continuous winder for web material includes two pairs of turret arms mounted for rotation with respect to each other on a common axis, and also includes a lay-on roll mounted for lateral movement toward and away from the axis of the turret arms.  The lay-on roll maintains pressure engagement with the winding roll until the interval of actual roll changing, when it moves from the wound roll into pressure engagement with the new core with the web running therebetween, whereupon the web is cut between the two rolls to complete the roll change.  The knife assembly for cutting the web is carried by another pair of pivotally mounted arms and includes a clamp mechanism on each arm which effects rotatable clamping engagement with the adjacent turret arm carrying the new core so that the knife arms and the core-carrying turret arms travel together throughout the actual operation of roll changing and thereby assure that the knife is held in proper relation with the core before the roll change is made and while it is being made.

Title: Method of stabilizing recombinant hepatitis b virus surface proteins from yeast
Inventor: KUBEK DENNIS
IPC: C12P21/00
Filed: 1990-12-03
Abstract: Recombinant hepatitis B virus surface proteins produced in yeast are rapidly and efficiently purified from yeast cell extracts in a high pH buffer.  The yeast cell extract is heat treated, cooled and the pH is reduced.  The surface proteins are then adsorbed onto wide pore silica followed by elution and concentration.  This method eliminates the requisite introduction of protease inhibitors, stabilizes the surface protein and improves product yield.

Title: Web and support belt separation for dry end of paper machine
Inventor: WULZ HANS-JURGEN
IPC: D21F5/04
Filed: 1991-04-15
Abstract: Abstract The dry end or dryer section of a paper making machine has a plurality of dryer groups.  Each dryer group comprises a plurality of heatable dryer cylinders, reversing rolls between each pair of the dryer cylinders in the group, and an endless web support belt which passes over a dryer cylinder and then a reversing roll and then the next dryer cylinder in turn in the group.  Between the last two dryer cylinders with which the lower side of the web comes into contact, there is an auxiliary guide roll over which the support belt travels free of the web, while the web travels directly from the selected dryer cylinder to the next reversing roll.  Alternately, the auxiliary guide roll is disposed between the reversing roll and the next dryer cylinder in the web path of travel.  Between the dryer cylinder and the auxiliary guide roll can be provided a second auxiliary guide roll which presses the web against the belt before the web separates from the web to pass to the auxiliary guide roll.  A tip cutter is arranged on the free or unsupported stretch of the web.  Other reversing roll arrangements are disclosed for separating the web from the support belt so that the tip cutter can act on the free stretch of the web.

Title: Gravel pack well completions with auger-screen
Inventor: CORNETTE HOLLEY M
IPC: E21B43/04
Filed: 1991-07-23
Abstract: A method and apparatus for installing a gravel pack completion which does not require the circulation of fluids during installation.  the gravel is first placed or preset within the completion zone and then a well completion tool (e.g. a fluid-permeable liner) having an auger blade thereon is lowered and rotated into the preset gravel without circulating fluid through the tool. Since the auger blade mechanically displaces the gravel upward as the tool is moved into the preset gravel, there is no need to flow fluid under pressure to "fluidize" the gravel as is required in prior completions of this type.
Patent CA-2049659-A1 (CA)
Inventor: BELL JEHU R
IPC: B29D30/46
Filed: 1991-08-21
Abstract: An ultrasonic cutting system for stock material temporarily bonds the stock material to an anvil incorporated in a processing table and cuts the stock material at a low angle with an ultrasonic cutting tool.  The ultrasonic cutting tool is mounted on a carriage assembly which traverses the width of the stock material.   The ultrasonic cutting tool  includes a cutting blade mechanically coupled thereto.   The cutting blade resonates in response to ultrasonic energy travelling axially therealong.  As the carriage assembly moves across the stock material, the stock material is first adhesively bonded or secured to the anvil by at least two rollers.   The rollers are mounted on the carriage assembly at a position slightly ahead of the cutting blade.  The rollers apply pressure  in  a  downward  direction  on  the  stock  material  to temporarily bond the material to the anvil and to prevent it from moving or vibrating during the cutting process.  As the carriage assembly moves across the stock material, the blade cuts through the stock material at a low angle, preferably at an angle of about 5° to 10° with respect to the horizontal.  After the blade has cut through the stock material, a trailing shoe, slidably moving along a channel guide formed in the anvil, removes the stock material from its adhesive bond with the anvil and allows the cut portion of the stock material to be removed for further assembly and processing into a tire.
