Apparatuses for heat-sealing thermoplastic materials include one or more cooperating sealing jaws which display mutually facing work surfaces with means for heating the thermoplastic material. When heating means in the form of a wire or a strip of electrically heatable resistor material are employed, extreme demands are placed on the anchorage of this to the sealing jaw, since elongation changes (...

A fire-retardant composition for treating: reconstituted wood products, natural wood, amino-resin based adhesives, polymeric materials, paints, paper, cardboard, corrugated board, plastics laminates, articles manufactured from brick-like materials or cement, including salts (acidic, neutral or basic) of acidic -aluminium coordination compounds in which the aluminium is coordinated with the oxygen ...

A viscous damper for influencing and retarding rotation of a shaft, particularly the reel shaft of a roll-down fire door. The viscous damper unit comprises a housing having radially extending lugs, a cover for mounting to a side face of the housing, and a rotor arranged to be trapped between the cover and the housing and rotatable with respect to the housing. The rotor provides a bore for receivin...

The guide wire is especially suitable for the percutaneous introduction of a balloon-tipped dilation catheter into a blood vessel. It comprises a flexible shaft (1) which has a proximal end and a tapering distal end (2, 3, 4). A flexible spiral (6) surrounds the distal end (2, 3, 4) of the shaft (1). The spiral (6) has a distal part (9) which can be visualised by X-rays, and a proximal part (8) wh...
