Title: Production of protein concentrates from animal tissues - such as whole fish
IPC: C11B1/10
Filed: 1969-03-19
Abstract: Protein concentrate suitable for use as a human food or an animal feed, is produced from animal tissues, such as whole fishes, by (a) comminuting the animal tissues, (b) subjecting the formed tissue suspension to evaporation in the presence of a volatile organic solvent, to remove most of the water, and simultaneous extraction with the solvent to remove part of the fats and part of the odour-providing components from the tissues, and (c) optionally further reducing content of fats and odour-providing component to a desired value by further extraction with fresh solvent. Evaporation is carried out by contacting the tissue suspension in countercurrent motion with the solvent vapour, removing water from the water enriched solvent vapour by rectification and recycling the recovered solvent vapour to the evaporation process.

Title: Electric tea or coffee machine with filter - has water outlet with overflow and throttle restrictor for even release of water
IPC: A47J31/44
Filed: 1979-03-05

Patent NL-8000991-A (NL)
IPC: B03D1/16
Filed: 1980-02-18
Abstract: The invention concerns a flotation apparatus for separating impurities, such as printing ink, or the like, from a fiber suspension that has been formed from waste paper. The apparatus includes a container for flotation of the suspension. A drive shaft extends into the container, either from above or below. A feed opening for suspension is defined at the bottom of the container. On the drive shaft is a pump impeller for impelling suspension into the container and downstream along the drive shaft. From the pump impeller there is a rotor located on the drive shaft for dispersing air that is introduced to the container by an air feed conduit which emits air into the region of the rotor. The drive shaft itself may serve as the air feed conduit and it may have air outlets at either or both of the pump impeller and the rotor. A foam withdrawal means for withdrawing the foam of impurities generated in the flotation apparatus has an inlet positioned at the axis of the cylinder which is at the axis of the rotor.
