Abstract: The invention relates to a composition comprising 50-99 wt. % of Na2SO4.10H2O and 0.1-5.0 wt. % of an alginic acid salt. Such composition may advantageously be used as a phase change material since the composition (and a pouch comprising the composition) remains flexible during the phase change. This was also the case when subjected to a high number of subsequent cycles of heating and cooling.

Abstract: Process for producing multi-layer frozen confections, comprising the steps of a. filling a first mold, having a mold bottom, mold walls and an open mould top, at least partly with at least one first substance to be frozen; b. freezing said at least one substance into a frozen part; c. releasing said frozen part from the first mold; d. positioning said frozen part in the first mold or in a further mold having a mold bottom, mold walls and an open mold top, leaving room between the frozen part and the mold bottom and mold walls; e. feeding at least one further substance to be frozen into the first mold during or after step d) or into the further mold before, during or after step d); f. freezing the frozen part and the further substance into a unitary frozen confection; and g.

Abstract: Method for the manufacture of cooling parts for a cooling garment comprising the application of an absorbing polymer material to a first layer of a permeable fabric, covering the first layer and the absorbing polymer material with a second layer of a permeable fabric and connecting together the first and the second layer in a connecting pattern, wherein the absorbing polymer material is applied in immobilized form and cooling garment, comprising cooling parts comprising a first layer of fabric and a second layer of fabric, the first and second layer having been connected together in a pattern, the pattern forming pockets, the pockets containing absorbing polymer material, wherein in addition to the absorbing polymer material the pockets further contain a water soluble polymer.

Abstract: Extruders for processing material have a selectively variable extruder volume. The extruders include an extruder barrel containing a bore sized to process 5 to 50 grams of material, wherein the bore has an upstream inlet portion for feeding the material to be processed and a downstream outlet portion connectable to an extruder exit for material processed through the extruder, and at least two recycle channels which differ from one another in at least one of volume, area of cross-section and length. A diverter valve of a flow control system is positioned at the outlet of the extruder for controllably directing material flow from the bore to either the extruder exit or at least one of at least two recycle channels.
