Title: Protective oxide layer production - by circulating clean sea water through heat exchanger tubes
Inventor: PEIKER KARL DIPL ING
IPC: C23C22/68
Filed: 1973-05-15
Abstract: A protective layer is produced on the surfaces of heat exchangers for ships' engines which will be exposed to the corrosive action of sea water by flushing the parts concerned with water, preferably clean sea water. The parts are first degreased and shortly before the flushing treatment is concluded, iron sulphate is added to the flushing agent. This accelerates the formation of a protective layer of oxides which would normally be delayed by the contaminated sea water near the shore. A smooth non-porous oxide layer provides no nuclei for cavitation or erosion. It ensures a longer life of all the parts concerned.

Title: Cotton seed delinter - which has an abrasive surface for separating lint and waste products from cotton seed
Inventor: WILLIAMS ORVILLE LEE
IPC: D01B1/06
Filed: 1973-07-21
Abstract: The cotton seeds are delinted inside a generally cylindrical chamber which is lined with an abrasive material such as for example interlocking bricks. Inside the chamber there is a rotor fitted with outwardly extending vanes leaving an annular space of about 2/16 inch. to 3/4 inch. The seeds enter the chamber under gravity and are then propelled through it under the influence of the air flow created by the rotor, and are de-linted by contact with the abrasive lining. A finger plate then assists the separation of lint, and waste matter from the seeds. Unlike the widely used saw and brush type of delinting device there is damage to the seeds during the process.
