Expanded thermoplastic microspheres are produced by heating unexpanded microspheres after they have been dried under agitation to a dry solids content exceeding 98 wt.%, pref. 99 wt.%. The microspheres, once dried, can be rewetted before expansion. - The dried unexpanded microspheres are pref. expanded by heating them using a number of overhead IR lamps located above a belt conveyor having an endl...

By increasing the oxygen content, and reducing nitrogen, less exhaust gas is produced, water is electrolytically decomposed, and improved combustion results. Hydrogen is fed into the engine, the internal combustion engine aspirates oxygen through a pipe connection and a filter. - The same occurs with ambient air which is regulated by a valve on the engine. Oxygen in the water tank is renewed by ai...

In a process for scale and oxide removal from metal (alloys), esp. (high) alloy steels and carbon steels, by a batch method or in systems with continuous transport equipment, the novelty is that the metal parts are pickled in one or more steps in an aq. iron chloride-sulphate and/or iron (III) chloride and/or iron (III) sulphate soln. which contains 15-200 g/l Fe(3+) ions and is either acid-free o...

A rope tensioner consists of a reel 11 for winding up slack of a rope 12 which is to be tensioned, and a lock 29, 30 arranged on the reel for securing a first rope part 12B, which extends in one direction from the reel and, after deflection, returns to the reel, and also a rope lock 28 arranged on the reel for securing a second rope part 12C which extends in the opposite direction from the reel. A...

The invention relates to a pallet for truck transport especially suitable for use on board refrigerated vessels having holds provided with devices in the hold floor, for example perforations, for introducing the cooling air into the hold. The pallet comprises a bearing frame 1 which, when the pallet is placed on the hold floor, for example, is arranged to delimit that surface of the hold floor whi...
