Title: Polycarbonate compositions having multiple phase impact modifiers therein
Inventor: RIEW CHANGKIU K
IPC: C08L69/00
Filed: 1989-10-03
Abstract: ABSTRACT           Polycarbonates are blended with an impact modifier to improve the impact resistance thereof.  The impact modifier is a multiple phase polymer system prepared by subsequent multiple stage polymerizations. The first phase which constitutes from about 50 percent to about 90 percent by weight of the multiple phase impact modifier is generally an elastomer such as an alkyl acrylate wherein the alkyl portion has from 2 to 18 carbon atoms.  The second phase polymer is generally a plastic type compound such as a vinyl substituted aro-matic, an alkyl methacrylate, or an alkenyl nitrile compound.  The impact modifiers are made without uti-lizing any crosslinking or grafting agents and thus are substantially free of any such bonds and are generally free-flowing powders.

Title: Process for the preparation of porous polyacrylonitrile polymer beads
Inventor: LEY DAVID A
IPC: C08J9/16
Filed: 1989-11-21
Abstract: 30,987 PROCESS FOR THE PREPARATION OF      POROUS POLYMER BEADS                       ABSTRACT Isotropic porous polymer beads having a high controllable surface porosity and large pore diameters from about 0.002 to about 5 microns are produced from solutions of an acrylonitrile polymer or a copolymer by a thermally-induced phase separation process including intensively shearing the polymer solution into small droplets.    The  use  of  mixed  solvent  non-solvent combinations   as   solvents   for  the  polymers,   and preferably reducing the polymer content in solution to below   10   percent   produces   high   pore   content, substantially  spherical  beads  having  a  morphology ideally suited to the chromatography of large molecules, such as proteins, and for enzyme-binding.

Title: Pipe interrupter
Inventor: OBERDORFER HANS
IPC: E03C1/10
Filed: 1989-11-23
Abstract: Abridgement A  pipe  interrupter,  which  is  particularly suitable for  installation  in  a  sanitary  fitting,  comprises   in a  housing  a  chamber,  into  which a water-supply passage, a water-discharge  passage  and  a  ventilation  path  open. Located  in  the  chamber  is  a  rolling membrane, which is fixed at the peripheral  region.   Normally,  thus  as  long as  there  is  no  reduced  pressure in the supply passage, the rolling membrane bears in  the  central  region  against the opening aperture of the ventilation path in the chamber, so that on  the  one  hand  no  atmospheric  air  may  enter and  on  the  other  hand  no  water  may  escape.  However, if  reduced  pressure  occurs  in  the  pipe  system,  which is  connected  to  the  supply  passage,  then  the  rolling membrane overturns so that  now  on  the  opposite  side  of the  central  region  it  closes  the  opening  point of the supply  passage  into  the  chamber.   On  the  other  side, a ventilation path to the chamber is exposed.  This ventila-tion  path  continues  by  way  of  a  through-flow  opening in  the  edge  region  of  the  rolling membrane towards the discharge  passage.   In  this  way,  water can  no  longer flow  back  into the supply passage and into the pipe system connected  thereto;  on  the  other  hand,  the   water-ways following the chamber are ventilated (Figure 2).

Abstract: A portable device for guiding a length of pressure sensitive adhesive coated tape partially onto the outer wrap of a roll of masking material adjacent one of its edges to provide a composite masking sheet for use in masking surfaces comprising a length of the sheet material having the tape adhered along and extending widthwise past one edge by which the composite masking sheet can be adhered to a surface.  The outer edge of the tape is not guided by the device, and a tendency that otherwise exists for the tape being adhered along the edge portion of the roll of masking material to move transversely away from the masking material so that less and less of the tape is adhered to the masking material is restricted by a tracking member mounted on a frame of the device between a hub supporting a roll of the tape and the roll of masking material.  The tracking member engages the rear surface of the tape along its edge that overlaps the masking material for less than the full width of the tape and deflects the tape toward a plane through the axes of the rolls of tape and masking material from a plane which is mutually tangent to the peripheries of the rolls of tape and masking material.
