Patent NL-8601320-A (NL)
IPC: A22C13/00
Filed: 1986-05-23
Abstract: Process for the manufacture of a piece of intestine of shrinkable plastic film suited to be filled with foodstuffs, in which the plastic film, having a tube shape, is lead onto a mandrel at a certain running-in speed while being kept at an internal pressure by means of air supplied from within so that it assumes a cylindrical shape and is shirred onto said mandrel, in which, during shirring, the plastic tube is more or less pleated with the aid of shirring wheels and in which, after a certain length of tube has been shirred onto the mandrel, the plastic tube is cut after the shirring wheels. According to the invention, the thus obtained piece of intestine is maintained in a condition in which it is free of stresses, other than those which are the result of keeping it in place and its being in a shirred condition, and then locally heated at its exterior surface to a temperature at which the plastic material starts to shrink, which temperature well exceeds the sterilization temperature but is below the melting temperature of the plastic material. On account of their quite irregular appearance, the synthetic intestines obtained from the piece of intestine thus treated, bear a great resemblance to some types of intestines.

Title: Tracer particle for fluidised bed system - automatically generates detectable magnetic field from incident light
IPC: G01P13/00
Filed: 1987-05-07
Abstract: The particle capsule has a transparent, elongated outer cover (11) with rounded ends. Within the capsule is a cylindrical block of material (12), with a coil (13) at one end and a photocell (15) at the other. The output from the cell is fed via wires (14) to the coil. The coil is much heavier than the cell and the centre of gravity (16) is thus nearer the coil end of the capsule. When a light is shone onto the bed, the magnetic field of the coil can be detected by sensors in the bed. The sensor outputs can be analysed to trace the path of the particle over the fluidised bed.
