Granted: 1991-09-10
Abstract: ABSTRACT         A polymeric porous membrane having a matrix made from an aliphatic thermoplastic polyamide or from an aliphatic thermoplastic polyamide/polyimide copolymer which has both relatively non-crystalline and relatively crystalline portions is provided.  A method for preparing such a membrane comprises dissolution of an aliphatic thermoplastic polyamide or polyamide/polyimide copolymer having crystalline and non-crystalline portions such that the non-crystalline portions dissolve.  At least some of the crystalline portions form a colloidal dispersion which is formed into a film.  Dissolved non-crystalline portions are subsequently precipitated to form the porous membrane matrix.  The pores in the membrane are defined by spaces between the relatively crystalline portions and at least some of the relatively crystalline portions are linked together by the reaction of a bis-aldehyde with the membrane matrix.

Abstract: ABSTRACT          What is disclosed is a face mask formed from a porous sheet made of a plurality of fibers.  The mask is formed into a generally cup shape shell that fits over the mouth and nose of the wearer and is held thereto by elastic straps attached to the mask that pass behind the head when the mask is worn.  The mask filters breathed air passing through the mask.  The border of the mask is more tightly compacted during forming.  The mask of the present invention features rearwardly projecting portions located on either side of the nose bridge area of the mask parallel to and close to the border of the mask.  The peak of the rearwardly projecting portions extend from the face mask in the direction of the face of the wearer of the mask to conform the portion of the mask close to its border to the contours of the face of the wearer between the bridge of the wearers nose and the upper areas of their cheekbones.  The more tightly compacted rearwardly projecting portions, rib elements and border cooperate to provide shape retention to the mask, and to provide a spring action that holds the mask firmly but comfortably to the face of the wearer even when they talk or change facial expression to prevent the passage of air between the mask and the face of the wearer.

Title: Preparation of retrovirus-free immunoglobulins

Abstract: Invention:  PREPARATION OF RETROVIRUS-FREE IMMUNOGLOBULINS   Inventors:  GAUTAM MITRA and MILTON M. MOZEN                Abstract of The Disclosure The effects of Cohn-Oncley cold alcohol fractionation on infectivity of two prototype retroviruses, mouse xenotropic type C and the LAV strain of AIDS retrovirus result in a significant reduction in retrovirus titer.  At least a 100,000-fold reduction of LAV was obtained when fraction-ating plasma to fraction II.  Adjustment to pH 4.0 at filtrate III was as effective for viral inactivation as was precipitation of fraction II from filtrate III with 25% ethanol.  Liquid immunoglobulin preparations spiked with LAV and incubated at 27° C for 3 days resulted in an additional 1,000 - 10,000-fold reduction of LAV titer.  Our results support the clinical and epidemiological evidence that therapeutic immunoglobulin preparations prepared by Cohn-Oncley cold ethanol processing (at least about 18% v/v alcohol, pH ? 5.4) and then stored at a pH equal to or less than about 5.4 and a temperature of at least 27° C for at least 3 days, do not transmit retroviruses such as the LAV strain of the AIDS virus.  Similar fractionation followed by storage at a higher pH (6.8) followed by a storage at a higher temperature (45° C) for at least B hours also appears effective in avoiding transmission of the retroviruses.

Granted: 1991-05-21
Abstract: ABSTRACT OF THE DISCLOSURE      A cache memory  subsystem couples to main memory through interface circuits via a system bus in common with a plurality of central processing subsystems which have  similar  interface  circuits.    The  cache  memory subsystem  includes  multilevel  directory  memory  and buffer memory pipeline stages shareable by at least a pair  of  processing  units.   A read in process  (RIP) memory associated with the buffer memory stage is set to  a  predetermined  state  in  response  to  each  read request which produces a miss condition to identify the buffer  memory  location  of  a  specific  level  in  the buffer  memory  which  has  been  preallocated.     The contents  of  the  buffer  memory  stage  are  maintained coherent with main memory by updating its contents in response to write requests applied to the system bus by other subsystems.   Upon detecting the receipt of data prior to the receipt of the requested data which would make the buffer memory contents incoherent,  the cache switches the state of control means associated with the RIP memory.  Upon receipt of the requested data,  the directory memory is accessed,  the RIP memory is reset and  the latest  data  is  forwarded  to  the  requesting processing  unit as  a  function  of  the  state  of  the control means.
