Patent CA-1340173-C (CA)
Inventor: INOUYE HIROSHI
IPC: C12N15/00
Filed: 1988-03-09
Granted: 1998-12-08
Abstract: Methods  and  products  are  provided  for producing and/or   purifying   virtually  any  hybrid  polypeptide molecule  employing  recombinant  DNA techniques.  More specifically,  a  DNA fragment  coding  for  a  protein molecule,  e.g.  a  polypeptide  or  portion thereof, is fused  to  a  DNA fragment coding for a binding protein such   as  the  gene  coding  for  the  maltose  binding protein.    The  fused  DNA is  inserted into a cloning vector  and  an  appropriate  host  transformed.    Upon expression,  a  hybrid polypeptide is produced which can be  purified by contacting the hybrid polypeptide with a ligand  or  substrate  to  which the binding protein has specific  affinity,  e.g.  by  affinity  chromatography. The  hybrid  polypeptide  so  purified  may  in  certain instances  be  useful  in  its hybrid form, or it may be cleaved  to  obtain  the protein molecule itself by, for example,  linking  the  DNA  fragments  coding  for  the target  and  binding  proteins  with a DNA segment which codes  for a  peptide  which is recognized and cut by a proteolytic  enzyme.  The present invention also relates to  certain vectors useful in practing the above process as  well  as  to  a bioreactor and methods employing the bound  hybrid  polypeptide,  e.g. where the bound target polypeptide  is  contacted  and  reacted with a sustance which  interacts  with  the  bound target polypeptide to produce a desired result.

Title: Apparatus for rotating and compressing a stack of pads
Inventor: HIRSCH JOHN L
IPC: B65B63/02
Filed: 1988-03-14
Granted: 1992-09-29
Abstract: Abstract of the Disclosure A machine for conditioning a stack of pads, such as sanitary pads, for packaging includes a rotor. Radially extending chambers having closed sides and open front and rear ends are fastened to the rotor. There is a compressor plunger in each chamber.  The plungers are carried on guide rods extending from cam follower brackets.  A stationary cam plate is mounted perpendicular to the rotational axis of the rotor.  The follower rollers are spring biased into contact with the periphery of the cam plate.  The chambers are incremented in angular steps starting with a position in which the chamber is stopped momentarily for being loaded with a stack of pads at which time its plunger is retracted.  As the loaded chamber increments in two angular steps to an unloading position, the plunger is driven out by the cam to compress the stack.  When the chamber rotates from loading position to unloading position, the pads are effectively turned so they are standing on their edges in this unloading position.
