Title: Control of water supply to programmable dishwashing machine - using rotating spray heads, with speed proportional to water pressure, and inlet valve to keep speed constant
Inventor: AVENWEDDE JOSEF
IPC: A47L15/46
Filed: 1992-10-24
Abstract: To control the supply of water, there is a solenoid valve in the water pipe which remains open until a predetermined quantity of water fills the tank where a pump then delivers it to the spray heads. The water pressure makes the spray heads rotate, the rotation speed being proportional to the pressure. When the required tank level is reached, the valve closes. The spray head speed is an indicator of irregularities in operation. A speed signal is delivered to the microprocessor. When the speed is within a certain tolerance of a set speed, the valve is closed. If the speed is too low, the valve is opened until the required speed is reached. ADVANTAGE - Energy-saving but still with excellent cleaning function.

Patent DE-4301084-A1 (DE)
Inventor: REBER ERWIN
IPC: A01D80/00
Filed: 1993-01-16
Abstract: In a rotary haymaking machine with a plurality of working rotors connected releasably to a machine frame (1), the object to be achieved is to mount the working rotors with as little play as possible in a particularly bend-resistant and therefore vibration-free manner, without impeding the possibility of adjusting the angular position of the running wheels. Moreover, the drive housings are to be capable of being sealed off without a gap against dust and lubricant. The object is achieved in that the working rotors are mounted on tubular sleeves (4) which are screwed to the machine frame (1) by means of a funnel-shaped flange (8) and through which pass adjusting shafts (21) which are connected at their lower end to parts (25) of a supporting mount for the running wheel and which, at the upper end, engage around a driveshaft (27) at a distance in a hook-shaped (26) or annular manner and are rotatably mounted above the latter in the machine frame (1). The play-free mounting makes it possible to seal off rotating drive parts (13, 14) of the working rotors relative to the casing (19) of the machine frame (1, 2) by means of an annular gasket (18). <IMAGE>
