Patent EP-0282813-A1 (EP)
Inventor: SCHEUFLER BERND DR
IPC: A01C7/10
Filed: 1988-03-02
Abstract: Single-grain seeder with rotating distributor elements which discharge a specific number of seed grains during each revolution, the distributor elements being assigned at least one sensor which counts the revolutions of the distributor elements, the sensor being arranged in a controlled loop, the command variable of which is the driving speed of the single-grain seeder or the distance covered by it per unit time. To make the monitoring of the number of seed grains actually discharged from a single-grain seeder simpler and more accurate, the drive of the distributor elements being variable as a function of the driving speed, in addition a seed-grain sensor (25) is assigned to at least one distributor element (14) and counts the seed grains (23) actually discharged as a function of the driving speed or as a function of the revolutions of the distributor element (14) determined by the first sensor (27), the desired number of seed grains theoretically discharged, determined from the revolutions of the distributor elements (14) by the first sensor (27), is compared in a distributor circuit with the actually discharged seed grains (23) determined by the seed-grain sensor (25), and a warning signal is generated if a fixed tolerance in the deviation between the nominal value and the actual value is exceeded. <IMAGE>
Patent EP-0306615-A1 (EP)
Inventor: ORTMANN HELMUT
IPC: F42B14/06

Abstract: The invention relates to a method for manufacturing a sabot projectile and to a sabot projectile manufactured by this method, in which a thin uniform layer of rubber is coated onto the rear gas-pressure receiving surface in a vulcanising tool with an injection mould for the purpose of fixing the individual sabot segments together and sealing them off from one another. 
<??>During the injection of the liquid sealing material into the injection mould, there is a danger that, as a result of the high pressure prevailing during this, sealing material will penetrate in an uncontrolled way into the cylindrical inner annular gap between the sabot and projectile body. 
<??>This can lead to considerable impairment of the separation behaviour of the sabot segments and to a reduction of the target-diagram quality. 
<??>According to the invention, this disadvantage is eliminated in that, before the sabot projectile is inserted into the vulcanising tool, the rear annular gap between the sabot and projectile body is sealed off by the application of a sealing means on the circumference of the projectile body. A sabot projectile manufactured according to the invention is characterised by a sealing ring (22) arranged in front of the rear annular gap between the sabot (12) and projectile body (11) and vulcanised into the rubber coating (19) applied to the rear gas-pressure receiving surface (18) of the sabot (12).

Abstract: The bottle stopper for freeze drying is made of rubber-elastic material and consists of a peg (1), having an essentially cylindrical outer circumferential surface (10a, 10b), and a circular flange (2) which is integral with said circumferential surface. The peg contains a hollow space (4) which is open towards the free peg end face (3) and, via a slot (11) towards the axially outer part of the circumferential surface (10b). Projecting from the outer circumferential surface and spaced apart are three cams (14a-14c) which are constructed as elongate beads and whose axially outer boundaries are located on a common transverse plane (Q3) adjacent to the peg end face. Constructed in the axially outer circumferential surface (10b) is a circumferential groove (16), whose axially inner side wall is located in the transverse plane (Q3). The cams define a first insertion position of the stopper, in which the container is still in connection with the atmosphere via the hollow space and the slot. The groove allows use of a stopper model both for containers with a completely smooth cylindrical borehole of the bottle neck and for those which have an inwardly projecting rib at the transition from the borehole to the end surface of the neck. <IMAGE>

Abstract: Regenerated adsorbent particles, such as activated carbon, are recovered from a wet oxidation-regenerated mixed sludge liquor from a wastewater treatment system by diluting and settling a blowdown slurry (20) from the wet oxidation reactor (12) to obtain a first aqueous phase (32) containing primarily regenerated adsorbent particles and fine ash particles and a first solids phase (28) containing primarily grit particles. The first aqueous phase (32) is combined with a portion (16) of the regenerated adsorbent particle slurry withdrawn from the upper portion of the wet oxidation reactor (12) and, after treatment with a dispersing agent (36) and then an anionic flocculating agent (44), the resulting mixture (46) is settled to obtain a second aqueous phase (54) containing primarily fine ash particles and a second solids phase (50) containing primarily regenerated adsorbent particles. The second solids phase (50) is recycled to the wastewater treatment system for re-use and, after treatment with a cationic flocculating agent (58), the second aqueous phase (54) is settled to obtain a substan­tially particle-free third aqueous phase (66) and a third solids phase (64) containing primarily fine ash particles. Slurries (28) and (64) containing the grit and fine ash particles are combined and dewatered prior to disposal.

Abstract: A pile cutter, in particular a hand-operated pile cutter, contains a blade which is connected to bearing bolts (10) and which can be lowered in an angle of inclination (9) relative to a table surface (1) in order to generate an oblique cut, and a cut-material holding-down clamp (5) for applying pressure to the pile of cut material, which flanks the blade, can likewise be lowered and precedes the descending movement of the cutting edge of the blade (6). The blade is here housed displaceably by means of bearing bolts (10) inside inclined longitudinal grooves (7) (angle of inclination 9) of the cut-material holding-down clamp (5) in such a way that the cut-material holding-down clamp (5) is pressed against the pile of cut material by the descending pressure of the blade before the cutting operation, and, when the downward pressure is reached and when the descending pressure is exerted again, the blade executes a longitudinal displacement superimposed on its descending movement, in order to generate an oblique cut by relative displacement inside the inclined longitudinal grooves (7). The cut-material holding-down clamp (5) is stressed permanently in the direction (13) of the pile of cut material. The manual control is connected to the bearing parts (10) of the blade (4) in such a way that, when the blade (4) is raised, the cut-material holding-down clamp (5) is finally raised with it only when the cutting edge of the blade has been raised to a height level covered by the cut-material holding-down clamp (5). <IMAGE>
