A method is described which enables automatic determination of the monitor sensitivity of a radiation emitting arrangement (in particular a laser diode and photodiode arrangement), which monitor sensitivity relates a level of a monitor signal (IM) generated by the arrangement to a corresponding optical output level (OL) of the arrangement. The method comprises the steps of: (i) supplying a varying...

An improved process for the production of a plasticizer containing dry, flowable polyvinyl alcohol (PVA) resin blend capable of thermoplastic processing. The process provides for the incorporation of plasticizers in an intimate contact with the PVA resin without heating, cooling, or extended drying steps. Specifically, PVA resin granules having an appropriately small particle size distribution are...

Provided is a high strength wet-laid nonwoven fabric having strength, i.e., tensile strength, tear strength and interlayer peeling strength, similar to those of a filament nonwoven fabric, and a uniformity similar to that of a conventional wet-laid nonwoven fabric. This nonwoven fabric is made of a fiber having a fiber diameter of from 7 mu m to 25 mu m and a ratio L/D of from 0.8 x 10<3> to 2.0...

The axle is designed as a hollow axle. Its inner wall is coated with a layer of viscoelastic material against which a coaxial cylindrical element is applied in a non-positive manner. The cylindrical element can be of solid design or likewise be designed as a hollow shaft with or without a spiral slot. To apply the layer of the viscoelastic material, the hollow shaft is subjected to a dipping opera...

Kneading compound with a long shelf life, in which the resin and curing agent components have sufficiently high viscosity for them to be arranged geometrically in such a manner that they have a common contact surface. This has the advantage that the resin and curing agent are always present in the optimum ratio and can be used as an adhesive, a filling material, a modelling compound or a sealant.

Foamed particles of a propylene resin are described which comprises, as a base resin, a random copolymer of propylene and 1-butene, said random copolymer having a 1-butene content of from 3 to 12% by weight. A foamed mold article is also described which is composed of a random copolymer of propylene and 1-butene, and having a density of from 0.015 to 0.09 g/cm<3>. A bumper core material for use in...

Isotropic porous polymer beads having a high controllable surface porosity and large pore diameters from about 0.002 to about 5 microns are produced from solutions of an acrylonitrile polymer or a copolymer by a thermally-induced phase separation process including intensively shearing the polymer solution into small droplets. The use of mixed solvent non-solvent combinations as solvents for the po...

Biaxially stretched, heat shrinkable monolayer and multilayer films comprising very low density polyethylene terpolymers of monomers (a), (b) and (c), where (a) comprises ethylene, (b) comprises a C6-C8 alpha-olefin and (c) comprises 1-butene or 1-hexene, have a very good combination of physical properties and processability including high shrinkage values and puncture resistance.

Improved reinforced polyurethane/urea articles are made by reacting an organic polyisocyanate with low viscosity imino/enaminefunctional compounds in contact with fiberous reinforcing agents.
