Title: Hydraulic motor with radial pistons in rotor - has peripheral ring rotating with pistons in rotor
Inventor: KOERNER HELMUT
IPC: F01B13/06
Filed: 1973-11-05
Abstract: The motor has a rotor containing radial cylinders each of which contains a piston reciprocating in the cylinder.

Title: Multideck baking oven control - boosts heat input for heating up period and reduces input before reaching working temp
Inventor: FISCHER GEORG
IPC: A21B1/40
Filed: 1974-04-13
Abstract: A multi-deck baking oven, fitted with a two-stage gas-or oil-fired burner and a flue gas circulation system is so controlled that the high heating input is applied during warming-up period. Just before the working temp. is reached, the input is reduced, manually or automatically, to the normal level. This ensures a speeded-up starting period but prevents burning the pastry by excessive heat, even when there is a frequent change in the baking periods. A simple time programmer cuts out the human element.
