Patent DE-3634539-A1 (DE)
Title: Variable venturi nozzle
Inventor: RIEKHOF PETER
IPC: B05B1/30
Filed: 1986-10-10
Abstract: The variable venturi nozzle makes it possible to significantly expand the range of uses of the traditional venturi tube and of the venturi nozzle according to DIN 1952. It represents a considerable improvement for flow regulation and control. The shape of a venturi nozzle is simulated with the aid of a highly flexible hose which is placed in a tube and stretched over the ends and fastened in such a way that tensile stresses are produced in the hose. If the air in the space between the surrounding tube and the hose is evacuated, the stream tube expands continuously in accordance with the amount of air evacuated, until the hose rests completely against the inner wall of the tube. The original shape of the nozzle can be restored by admitting air to the evacuated space. This means that it is possible, with the aid of defined negative pressures, to achieve any desired diameter ratio. Since the variable venturi nozzle is in all cases more advantageous in terms of flow than any other restriction element, it can be assumed that energy advantages will be obtained.

Patent DE-3700843-A1 (DE)
Title: Apparatus for carbon-soot blending by absorption
Inventor: CHRISTIAN PAUL
IPC: B01D47/06
Filed: 1987-01-14
Abstract: Liquid spray apparatuses having a gas- or air-permeated treatment zone and an integrated tunnel in the spray chamber of the liquid bath have a high degree of cleaning. Carbon-soot particles which are situated above the liquid bath - in the flow area - are entrained and discharged with the clean gas. The integrated tunnel in the treatment zone prevents the discharge-entrainment of carbon-soot particles and does not have a negative effect on the gas-air stream. There are no downtimes due to filter exchange-cleaning, since the tunnel cleans itself.
Patent DE-3702807-A1 (DE)
Title: Device for cooling foods
Inventor: MINNAMEIER PAUL
IPC: F25D3/10
Filed: 1987-01-30
Abstract: The known cooling devices for foods, such as refrigerators, freezer chests and cooling rooms, are dependent upon an electric mains supply, difficult or impossible to move and associated with relatively high investment costs. The new device for cooling foods consists of a gas-filled pressure bottle 1 with a pressure control/reducing valve 2 connected thereto, a thermostatically controlled gas-supply arrangement 4 and a vessel, in which the material to be cooled is situated. The gas is preferably CO2; it cools on its expansion. The cooled vessel is preferably a thermally insulated plastic bag 17. The new cooling device is movable, independent of the supply mains and makes it possible to adapt the cooled vessel spatially to the material to be cooled. The new cooling device moreover gives rise to relatively only very low investment costs. With the new cooling device, a piece of freshly killed furred game for example can be stored in a cooled manner at a temperature of 5@C for a number of days freely suspended in a thermally insulated plastic bag.

Patent DE-3722360-A1 (DE)
Title: Fluidised bed calcination
Inventor: MUELLER HORST PROF DR SC TECHN
IPC: C01F5/06
Filed: 1987-07-07
Abstract: The fluidised bed calcination relates to a process for preparing materials rich in alkaline earth metals from carbonates for preferable use in pollutant reducing facilities. The aim of the invention is, utilising the heat of combustion of fuels suitable for the fluidised bed, to produce a highly active aggregate, preferably for flue gas purification, which is characterised by an increased proportion of alkaline earth metal oxide. This is achieved according to the invention by fuel and granular milled materials containing alkaline earth metal carbonate, such as, for example, limestone, being fed into a fluidised bed as fluidised bed material in such a ratio that an optimum calcination reaction proceeds at constant bed temperature. This eliminates cooling of the fluidised bed by immersed heat-exchanger surfaces or similar devices.   The reaction products are conducted away continuously. <IMAGE>

Title: Firing safety device for a firing bolt which is located in the automatic propellant charge detonator of a tube weapon (weapon with a barrel) base piece
Inventor: GAMPE EGON
IPC: F41A17/58
Filed: 1987-08-27
Abstract: In the case of known gun firing bolt devices, there is no functional relationship between an opener lever, a breech wedge and an automatic propellant charge detonator, so that uncontrolled firing (caused, for example, by vibration of the gun) can not be precluded, even during the interlocked time. The new firing safety device is intended to secure the firing bolt in a positively locking manner within the automatic propellant charge detonator as long as the breech wedge is not completely interlocked with respect to the base piece by the opener lever. To this end, a firing safety device 1 is arranged on the breech wedge 13 and consists of a two-armed rocker lever 8 and a locking mechanism 12. One arm 9 of the rocker lever 8 engages in a positively locking manner in a control cam 10 arranged on the opener lever 6, as a result of which the other arm 11 operates a locking mechanism 12, which is arranged in the automatic propellant charge detonator 2, in such a manner that the locking mechanism 12 assumes a locking position with respect to the firing bolt in a breech wedge position which is not interlocked with respect to the base piece 3 by the opener lever 6, and cancels the locking position in a breech wedge position which is interlocked with the base piece 3 by the opener lever, in order to carry out the firing motion of the firing bolt 4. <IMAGE>

Patent DE-3831662-A1 (DE)
Title: Fuel injection system
Inventor: HOFBAUER PETER PROF DR ING
IPC: F02M69/14
Filed: 1988-09-17
Abstract: Fuel injection systems of this type are provided for internal combustion engines which are used in vehicles and are therefore subject to exacting requirements with regard to accurate and fault-free fuel metering. Known devices have the disadvantage that vapour bubbles can occur in the injection lines, especially after prolonged static phases, as a result of which the fuel injection can fail. In order to overcome the said disadvantage, the new system has the characteristics that a distributor, rotating synchronously with the internal combustion engine shafts, connects one end of the distributor lines leading to the injection valves to the fuel feed system and the other end to the fuel discharge system during those phases in which no injection is performed by way of the said lines. The new fuel injection system is cooled by a scavenging flow in the distributor and housing. Vapour bubbles are thereby prevented. Vapour bubbles occurring when the engine is at a standstill are flushed out at the onset of scavenging.
