Title: Asparagus bed ridging attachment for tractor hitch - has height of ridge monitored via pressure on upper flap with automatic correction for ridging action
Inventor: EBERT REINHARD
IPC: A01B13/02
Filed: 1992-01-16

Title: Prepn. of foundry filter dust for environment-friendly disposal - in which dust is mixed with binding material, pressed to form solid bodies, and fused in blast furnace
Inventor: GEPPERT BERTHOLD
IPC: C22B7/02
Filed: 1992-03-07
Abstract: In a new procedure for the preparation of foundry filter dusts for dumping, the dust is mixed with a liquid binding material, the mixture is isostatically presseed to form solid bodies, and these bodies are charged as an additive into a blast furnace in which they are fused.

Natural binding materials such as glucose syrup, corn starch, water-glass etc. are used. Additives suitable for the blast-furnace process may be mixed with the dust and binder in powder or granular form. Metal powder or swaft from metal working processes may also be added to the mixt.. USE/ADVANTAGE - For disposal of dusts in foundries. An economical method is provided by which these environmentally damaging dusts can be converted to a form in which they can be safely dumped.

Title: Aerosol generator
Inventor: RUDOLPH ANDREAS DR ING
IPC: B01F23/30
Filed: 1993-04-21
Abstract: The invention relates to an aerosol generator, in particular for the generation of monodisperse aerosols such as calibration aerosols for testing measuring instruments or filters, dosing aerosols for visualising faults or inhalation aerosols for medical purposes. In a Sinclair-La Mer aerosol generator, between core source (4) and saturator (9) is connected a core separator element (7) and a bypass equipped with a valve (6) bypassing the core separator element. By a combination of the bypass round the saturator and setting the total volumetric flow rate and the part-streams, for a relatively variable aerosol concentration, in a large range particles of a desired uniform size can be generated with high precision. First measurements verify that the standard deviation in the overall particle size range of up till now 0.1 to 8  mu m is significantly below 1.15. <IMAGE>

Title: Pulsation damping for a fuel injection system
Inventor: STEFFEN FRANZ-JOSEF
IPC: F02M63/00
Filed: 1993-07-01
Abstract: Known fuel injection systems for internal combustion engines with self-ignition have a fuel injection pump from which the fuel is delivered to the injection nozzles by way of high pressure fuel lines. On completion of the injection sequence, unwanted fuel is discharged into a fuel return line. In this process pulsation oscillations occur in the fuel return line, which can lead to destruction of the fuel return line. According to the invention, hose lines 5 are inserted into the fuel lines 2, 2' and the fuel return lines 4, 4', which hose lines by means of elastic deformations reduce the pulsation oscillations to such an extent that no damage to the lines 2, 2', 4, 4' occurs. Compressed air or an inert gas or gas mixture can also alternatively or additionally be injected into the fuel return line 4, 4'. <IMAGE>

Title: Brake wheel for carrying out stationary marine-engine trials
Inventor: BEGLER WOLFGANG DR ING
IPC: B63B9/00
Filed: 1993-07-31
Abstract: The propeller (1) is given the characteristic of a brake wheel by a casing (2) which completely encloses the propeller (1) of the ship, is open in the hub area and is attached before the ship is launched. Propeller thrust and stream are prevented at full engine power. The power input is effected by pumping work inside the casing (2). After the stationary trial is complete, the casing (2) can be dismantled from the propeller (1) when the ship is floating. Dry-docking of the ship is thereby dispensed with. Adjustable drivers (3), stops (4) and distance pieces (5) in the casing (2) enable it to be adapted to various blade numbers and shapes within a certain diameter range. Economic advantages over known brake wheels are in particular the reduced processing time for the fabrication of the ship in the yard and the cost reduction through avoiding dry-docking. <IMAGE>
