Patent CA-2053697-A1 (CA)
Inventor: CHASE PETER D
IPC: E04F15/04
Filed: 1991-10-18
Abstract: The invention is directed to a tongue and groove product which comprises a first and second major surface and a first and second longitudinal edge.  The first longi-tudinal  edge includes means defining a  longitudinally-extending groove.  The second longitudinal edge includes a longitudinally-extending  protruding  tongue  for  inter-lockingly engaging a complimentary grooved longitudinal edge of an adjacent tongue and groove board.  The protrud-ing  tongue  has  an  upper  and  a  lower  longitudinally-extending  surface.    The major design  feature  of  this invention is that the protruding tongue has at least one substantially vertically-extending opening formed herein. Each of  these  openings extends through the protruding tongue from said longitudinally-extending upper surface to said longitudinally-extending lower surface for providing at least one drain path for water to drain by gravity from said  first major  surface downwardly through each  said vertically-extending opening.  This prevents an accumula-tion of water on the tongue and groove board.   In the preferred case,  the  opening  in  the  protruding  tongue comprises a substantial vertically-extending notch.

Title: Determination of dna sequences of a novel group of major grass pollen allergens and the synthesis of their corresponding recombinant proteins
Inventor: MOHAPATRA SHYAM S
IPC: A61K38/00
Filed: 1992-04-22
Abstract: ABSTRACT            Complementary DNA molecules encoding a novel group of major grass pollen allergenic proteins were isolated using  recombinant  DNA techniques.    The  complete nucleotide and deduced amino acid sequences for three allergens of Kentucky bluegrass (Poa pratensis) pollen, are disclosed.   Recombinant DNA molecules and hosts transformed with them, which produce the allergens or their peptides, and methods of characterizing these products are described.  In appropriate hosts these DNA sequences  permit  the  production  of  recombinant allergens which are useful for (i) the diagnosis of allergic  and  asthmatic  diseases  caused  by  the corresponding natural pollen allergens, and (ii) the development of effective therapeutic agents for the treatment  of  these  diseases.    Furthermore,  using antisera to the recombinant allergens, ten antibody binding peptides have been defined. One or more of these  epitopes  either by themselves  or  covalently linked with other peptides or polymers may be used for diagnosis and therapy of allergies.
