Abstract: A pickup 21 is connected with a portioning element that carries out individual portioning operations between two portioning pauses. By means of a sensor 22 and a counter 29 the actual values of the portioning operation steps are measured and are compared in a comparator 35 with a desired value from a desired-value setter 30. When the actual value reaches the desired value the programmed controller 27 for the next portioning operation and simultaneously the counter 29 is reset via the line 38. Thus the overrun of the portioning element after switching off is counted for the next portion. With each difference between desired value and actual value of a preceding portioning operation thus effectively the remaining desired value for the next portioning step is corrected.

Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.

Abstract: A method of and apparatus for dynamically mechanically bonding together a plurality of laminae, at least one of which comprises thermoplastic material: for example, polyethylene. In one aspect of the invention the laminae are forwarded in face to face relation through a pressure biased nip between a patterned nip defining member and an opposing nip defining member (eg, a relief patterned cylinder and an anvil cylinder) which members are independently driven to maintain a predetermined surface velocity differential between them. In another aspect of the invention which is particularly useful at intermediate and higher line velocities --preferably for line velocities of about 300 feet or more per minute and, more preferably, for line speeds of about 450 feet or more per minute -- the nip defining members say be operated with equal surface velocities. In each of these aspects of the invention, the members may be biased towards each other to provide a predetermined pattern-element-psi loading; and, additionally, they may be independently heated to provide each with an elevated surface temperature which is, preferably, in a predetermined range below the melt temperature of the thermoplastic lamina disposed closest to or in contact with each respective nip defining member as the laminae are forwarded through the nip. <IMAGE>
