Title: Delivering metered dough portions from hopper by piston - reciprocated by cam action in rotary cylinder without unnecessary pressure application
Inventor: YALCINKAYA NACI
IPC: A21C5/02
Filed: 1990-10-18
Abstract: Through an aperture at the top of a reciprocatingly rotating cylinder a portion of prepd. dough is drawn by suction by a piston, with any surplus dough returned to the hopper.

Patent DE-4224472-A1 (DE)
Inventor: LOEFFLER ALFONS
IPC: F16H61/14
Filed: 1992-07-24
Abstract: The bridging coupling is actuated by an annular piston to which the converter internal pressure is applied on one side and a closing pressure in the closing direction. The closing pressure is controlled by a precontrolled regulating valve depending on the outpout pressure of the converter and a control pressure depending upon further operating parameters. With the coupling open, the closing pressure in the closing pressure chamber remains below the internal pressure of the converter by a specified value. This ensures that the bridging coupling responds quickly and can be precisely regulated within narrow tolerances. In addition, only little power is needed for regulation.

Title: Progressive movement of engine-less gliding vessel travelling in water by changing centre of gravity
Inventor: WASILJEW WSEWOLOD
IPC: B63G8/22
Filed: 1993-01-07
Abstract: The device constitutes a glider with air chambers in its upper section. During upwards movement, the air is directed from the air containers through valves, and during a dive is bled off while the centre of gravity of the device moves from plus to minus.

Title: Heating boiler for low-pollutant combustion
Inventor: PINSCH EDMUND
IPC: F24H1/28
Filed: 1993-02-11
Abstract: In order to diminish the formation of nitrogen oxides in heating boiler installations and at the same time reduce the formation of carbon monoxide it is proposed that the burner flame (15) in the region of the mouth (7) of the flame be fed with a portion of the flue gas stream (15) in a recirculating manner and that the flow velocity of the flue gas stream (15) fed in be increased by a venturi nozzle-like acceleration profile (12), whose outlet is directed at the inner cone (14) of the flame. This measure causes the relatively cold flue gas stream (15) to be injected into the inner cone (14) of the flame and, as a result of a reduction in the combustion temperature and in the oxygen partial pressure, leads to the formation of nitrogen oxides being minimized, the outer flame zones remaining relatively hot and complete combustion taking place, so that little carbon monoxide is formed and the discharge of unburnt hydrocarbons is low. <IMAGE>
