Title: Milk cooling - using flow cooling for various milk yield levels in compact milking assembly
Inventor: JACKISCH HANS
IPC: A23C3/04
Filed: 1991-10-17
Abstract: The cooling system for a fluid, esp milk in a milking assembly, has a milk collection and delivery unit combined with a flow cooling principle. Pref. a programmable memory controls the final milk temp. according to operator needs. The milk temp. is held at a constant through the heat transfer through the infinitely variable controlled milk vol. as a milk pump connected to the milk delivery. Different cooling capacities are available according to the milk yield. The heat transfer is optimised by insulating the container for the cooling sole into separate hot and cold water zones. The milk is finally cooled in a double-walled milk tank. The cooling capacity is matched by simple refrigerating conversion of the plate size. For automatic cleaning, the milk collection unit also acts as a rinsing vessel. ADVANTAGE - The system is compact, and gives a rapid cooling of the milk from the cows to storage temps., with low cost and little space requirements, independently of the actual milk yield.

Title: Lifting boat out of water - uses inflatable bodies, which are fastened to hull
Inventor: KUEMPEL GOTTFRIED
IPC: B63C7/10
Filed: 1992-04-29
Abstract: The method employs one or more buoyancy bodies, which are fastened to the boat.

Patent DE-4226754-A1 (DE)
Inventor: SCHEFFEL MARTIN
IPC: F16F9/50
Filed: 1992-08-13
Abstract: A particular prior art suspension system suffers from the disadvantage that is is very stiff at high working pressures and, when operating at low pressures, requires the displacement of very large volumes of hydraulic fluid.
