Title: Diffuser for introducing or removing gas in rivers, lakes, etc. - in which gas is diffused through silicon@ rubber hose which is woven into fabric in which it acts as weft or warp
Inventor: WERNER CHRISTIAN
IPC: C02F7/00
Filed: 1991-01-30
Abstract: Diffuser has a silicon rubber membrane hose, which is woven into a flat fabric which holds it securely, protects it from mechanical damage, and acts as a medium for the transfer of oxygen to the water from the microbubbles diffusing through walls of the hose. An increase in the bursting pressure of the hose is also provided. The hose (1) is opt. reinforced and may serve as weft or warp in the formation of the fabric. The hose may also form a continuous weft by being placed alternately from left to right and from right to left. A number of hoses may be placed parallel to each other to form the warp of the fabric. The fabric may have a right-to-left warp made of polyamide or another plastic. Lateral movement of the hose is prevented by the mesh configuration. The diffuser may be used as direct contact surface for activated sludge. Weights are attached to the fabric so that it will sink to the bottom of the watercourse, lake, etc. USE/ADVANTAGE - Used for introducing gases into or removing gases from, and esp. for introducing oxygen, into, water in lakes, rivers, etc. An inexpensive diffuser is provided which reduces the formation of gas bubbles when introducing gases into a water course, and makes possible the simultaneous removal of carbon dioxide from the water.

Title: Combined fuel injection pump and injector - uses hollow plunger, spring pressurised needle and helical by=pass passages in plunger body
Inventor: GOLLE HERRMANN DR ING
IPC: F02M45/12
Filed: 1991-03-18
Abstract: The injector housing contains a hollow plunger (2), inside which is the injector needle (3). This is held against the nozzle (8) by a spring (4) bearing against the inside back wall of the plunger. A thin plate (6) limits the backward movement of the needle with respect to the plunger. Fuel is delivered to the pressure chamber through a channel (9) in the housing. On its downward stroke, the plunger first shuts off the fuel supply opening (10) and then pressurises the fuel sufficiently for it to unseat the needle and atomise through the nozzle. On the return plunger stroke, the increased spring pressure rapidly slams the needle shut against the nozzle. Rotation of the plunger body by an electric stepping motor (14) allows inclined pressure release passages (11,12) to regulate the fuel injection quantity. By-pass fuel re-enters the fuel line through passages (15,16) and a sealing ring (17) prevents fuel leakage outside the injector housing. ADVANTAGE - Space-saving; rapid shut-off at end of working stroke.
