Title: Gelling material and gelling method
Inventor: FUJIURA YOJI
IPC: A61L15/62
Filed: 1992-01-02
Abstract: ABSTRACT       The  invention  concerns  a  gelling  material  for gelling aqueous fluids,  medical wastes containing aqueous fluids,  body  fluids  collected  by  suction  in  body  fluid suction equipment.  The gelling material comprises a water-absorbent composed of a water-absorbing resin in the form of powders or granules,  the water-absorbent being wrapped in water-disintegrating paper or a water-soluble film or a laminate sheet obtained by laminating water-disintegrating paper  and  a  water-soluble  film.   The invention  also concerns  a  method  of  gelling  aqueous  fluid  and  medical naste by adding the gelling material to the aqueous fluid or medical waste.  The aqueous fluid or medical waste can be gelled conveniently and in a short period of time.  The gel thus produced never releases absorbed fluid even when an external pressure is applied to it.       Thus,  the invention is useful for the treatment of aqueous  fluids  such  as  sludge-like  wastes  produced  in plants and also of medical wastes and body fluids.

IPC: A23G3/02
Filed: 1992-06-08
Abstract: Abstract An elastic molding die is composed of an elastomer laminate film, of which the innermost layer is formed of an elastomer is not containing fillers.  The innermost layer elastomer is preferably an oil-resistant elastomer. Alternatively, an oil-repellent agent may be contained in the innermost layer elastomer. The outer layer may be formed of an elastomer containing fillers.  Furthermore, an oil blocking layer can be provided between the inner layer and the outer layer.  A master model is dipped in an elastomer solution not containing fillers, heat dried to form a gelled elastomer film, the film is coated with a coagulant, dipped again in an elastomer solution, taken out, gelation treated, and the elastomer film is peeled from the master model to obtain an elastomer molding die.  In another method, a once-formed hollow elastic molding die is turned inside out, pressed in with a gas to swell, the swollen die is coated with an elastomer solution not containing fillers, heat dried, and turned it again inside out.

Title: Vector to produce biologically important peptides
Inventor: BALGANESH TANJORE S
IPC: C12N15/00
Filed: 1991-06-12
Abstract: In this patent application we have described the construction of a novel secretion vector based on E.coli enterotoxin coding sequence. We have shown categorically that pre and pro region of toxin gene are absolutely necessary for extracellular secretion of the stable toxin. We have also shown with specific examples that when the nucleotide coding sequence of a heterologous peptide is fused in frame to the end of the pro region in the st gene, the resultant vector in an E.coli host secretes extracellularly correctly processed heterologous peptide. This application also includes construction of suitable vectors where this gene fusion can be achieved. General methods to create such fusions involving a) recombinant DNA technology and b) the use of site directed in vitro mutagenesis, have also been described. A general method of purification of heterologous peptides is also described in this application. This novel vector system can be used for hyperproduction and extracellular secretion of peptides of biological importance.

Title: Repressors of the trans-activating function of papillomavirus e2 proteins
Inventor: ANDROPHY ELLIOT J
IPC: C12N1/21
Filed: 1992-01-28
Abstract: This invention relates to E2 trans-activation repressors which interfere with normal functioning of the native full-length E2 transcriptional activation protein of the papillomavirus: Native full-length E2 trans-activation protein activates transcription of papillomavirus only through binding to DNA, and it binds to DNA only in the form of a pre-formed homodimer -- a pair of identical polypeptide subunits held together by non-covalent interactions. The E2 trans-activation repressors of this invention are proteins, polypeptides or other molecules that dimerize with full-length native E2 polypeptides to form inactive heterodimers, thus interfering with the formation of active homodimers comprising full-length native E2 polypeptides, thereby repressing papillomavirus transcription and replication. The E2 traps-activation repressors of this invention are advantageously used in the treatment of papillomavirus-infections and their associated diseases.

Filed: 1992-05-01
Abstract: A conveyor transport system for delivering fruits or vegetables to a longitudinal passageway (22) defined by two sets of opposing endless loop conveyor chains (24). A plurality of tensioner assemblies (30), which have two opposing pairs of independently acting chain sprocket assemblies (70 and 100), are provided to independently tension each set of conveyor chains (24) along both an x and a y axis so that each individual food product, regardless of shape and size, is subjected to uniform chain tension. Each pair of opposing chain sprocket assemblies are interconnected to a single cam ring (34 and 52), such that displacement of one chain sprocket by food product results in reciprocal and equal displacement of the other opposing chain sprocket, thus facilitating centering of the food product as it is delivered to cutter blade assembly (200).
