Patent FR-2159553-A1 (FR)
Title: Rotary cement kiln - with planetary, exit cooling tubes with supplementary cooling to prevent adhesion of sticky clinker
IPC: F27B7/40
Filed: 1971-11-02
Abstract: Rotary cement kiln has planetary cooling exit tubes with cooling air is injected in counter current. At the bend of the tubes, a supplementary cooling air duct is provided close to the hotter part of the clinker in the tube. This provides rapid cooling of the surfaces of the clinker particles so that they do not stick to the surfaces of the exit tubes. Cheaper material can thus be used for the tubes and wear on the tubes is considerably reduced.

Title: Automatic fish gutting machine - for use on high-sea trawlers
IPC: A22C25/14
Filed: 1972-02-14
Abstract: Machine can deal with very large fish, such as hake, haddock, codfish etc. It comprises a U-shaped eviscerating tool which descends by gravity until it rests on the base of the abdominal cavity of the fish; this has previously been opened by a longitudinal incision by a rotary tool.
