Title: Paper machine dryer fabrics
Inventor: BHATT GIRISH M
IPC: D21F1/00
Filed: 1995-07-11
Abstract: A paper machine dryer fabric in which at least a portion of the component yarns are monofilaments comprised of a copolymer of dimethylolcylohexane, terephthalic acid, and isophthalic acid, and an effective amount of a hydrolysis stabiliser. The molar ratio of terephthalic acid to isophthalic acid used in preparing the copolymer is about 83:17, and the copolymer has an intrinsic viscosity which is greater than about 0.75 dL/g.

Filed: 1995-01-20
Abstract: A moldable panel (10) having a predetermined shape for cushioning and protecting protrusions and areas including a flexible elastomeric thermoplastic honey comb panel (11) and a rigid thermoplastic plate (12). The honeycomb panel has a honeycomb core (14) formed of undulated strips (18, 20) of resilient thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells. The core (14) has a first face formed by a first extremity of the cell walls and a second face formed by a second extremity of the cell walls. The core (14) is maintained in its expanded configuration so that it can be used to anisotropically flex to stabilize and spread the load experienced by a user of the moldable panel (10). The core (14) is bonded to a first surface of the rigid thermoplastic plate (12). The plate is heated to a first temperature which is sufficient to mold or form the plate into the desired shape, but insufficient to melt the bonds formed between the honeycomb panel and the plate, and the bonds between the strips of the honeycomb panel. The second face of the honeycomb panel is heated to a second temperature, lower than said first temperature, to relieve stresses built up in the panel as the plate is being molded.

Inventor: MINTER STEPHEN JOHN
IPC: C12Q1/68
Filed: 1995-05-30
Abstract: Amplification of nucleic acids using oligonucleotides immobilised on solid phase supports is disclosed. Target nucleic acid strands (in a sample to be analysed) are hybridised to the oligonucleotides and copy target strands (incorporating immobilised oligonucleotide) are produced using the target strands as templates. The target strands are denatured from the copy target strands and rehybridised to non-extended oligonucleotides.  In the next step, new copy target (1) strands are synthesised from the oligonucleotides hybridised to the target strands, and simultaneously copy target (2) strands are synthesised using previously generated copy target (1) strands. Sequence of denaturing, rehybridising, and producing copy target (1) and copy target (2) strands is repeated as often as necessary to give the desired degree of amplification.
