Patent DE-3107256-A1 (DE)
Title: Apparatus for material separation
Inventor: BRUKE RICHARD
IPC: B01D21/04
Filed: 1981-02-26
Abstract: An apparatus (10) for separating off solids from a liquid and solids which float on the liquid surface includes a vessel (16), the cross-sectional area of which decreases from one end (17) to the other end (18) of the vessel. In a region near a top edge (15) of the border (11) of the vessel at the end (17) are arranged in part a feed element (30), in part an overflow (20) and in part a gap (22). The liquid fed to the vessel forms a liquid stream which is chiefly directed away from the boundary (11) of the vessel, the liquid stream lying at least at the beginning in the liquid surface or immediately beneath, those solids which float on the liquid surface being carried along with the liquid stream to the end (18) having the smallest cross-sectional area of the vessel. The liquid stream gradually turns downwards to the bottom of the vessel and back to the boundary (11) of the vessel, solids present in the liquid sedimenting, in order to rise again in the vicinity of the boundary of the vessel and to flow off over the gap (22) at the edge (21) of the overflow. <IMAGE>

Title: Arrangement for feeding lubricant to crankshaft bearings
Inventor: DANCKERT HERMANN DR ING
IPC: F01M1/06
Filed: 1981-03-11
Abstract: In an arrangement for feeding lubricant to the crankshaft bearings of a multi-cylinder reciprocating piston engine, a lubricant duct running essentially parallel to the axis of the crankshaft is provided in a cylinder block, which duct is connected to the bearing bores assigned to the crankshaft bearings in that bores for securing screws of bearing caps assigned to the bearings are provided, which bores intersect the main lubricant duct. The securing screw bores are then connected to the bearing bore by way of recesses arranged in the bearing part joint or also by relatively short bores made obliquely in the bearing block or in the bearing cap. In making the main lubricant duct by casting, it is proposed that this duct be of conical design and that the wall intersecting the securing screw bores then run essentially parallel and possibly flat to a line joining the axes of the securing screw bores. <IMAGE>

Patent DE-3146448-A1 (DE)
Title: Cylindrical safety vessels of steel for high pressures with simultaneously high temperatures
Inventor: HERTEL WILHELM DIPL ING
IPC: B01J3/04
Filed: 1981-11-24
Abstract: The circular-cylindrical vessels or pipes (Figures 1 and 2) consist of steel, and the cylinder shell can also be utilised for absorbing tensile stresses. The axial clamping of the vessels is located outside the heat insulation. The cold mounting of the vessels on the floor and at the cover allows the permissible expansion of the clamping steel to be adapted to the thermal expansion of the vessel to be clamped. As a result of the interposition of spring elements, inadmissible axial tensile stresses and axial thrusts in the safety vessel are impossible. Bursting of the vessel due to cracking of an annular weld can be excluded. The safety vessel consists of a plurality of circular cylinders in mutual contact. The inner cylinder shell is water-tight and/or gas-tight, and the outer cylinder shells are formed in any desired width by a row of rings. The supports provided on one of the two ends on the cover and/or on the bottom of the vessel do not participate in the heating of the pressure vessel, so that thereby longer clamping members are possible which allow stressing in the vessel by higher temperatures. The circular-cylindrical safety vessels eliminate the limitation of the temperature and wall thicknesses, the risk due to bursting and the uneconomical cost of the pressure vessels hitherto used in power station construction and process engineering. <IMAGE>

Patent DE-3247359-A1 (DE)
Title: DC motor without a commutator
Inventor: MUELLER ROLF DR ING
IPC: H02P6/14
Filed: 1982-12-22
Abstract: In the case of a DC motor (10) which has no commutator and whose stator winding (25) is operated in a bridge circuit (40'), it is necessary to prevent all the transistors in the bridge circuit (40') being in the switched-on state simultaneously. A delay capacitor (87) and two driver stages (54, 88 and 94, 95) are provided for this purpose, which have a low internal impedance whenever the associated bridge transistor is switched off, so that this transistor is switched off quickly. In contrast, when this transistor is switched on, it has a high internal impedance so that only a relatively small switching-on current can flow which initially has to reverse the charge on the delay capacitor (87) before it can switch this transistor on. The bridge transistors are preferably Darlington transistors having a high current gain. - An adequate current pause is thus produced between one pair (for example 71, 72) of transistors in the bridge circuit (40') being switched off and the subsequent pair (for example 70, 73) of transistors being switched on. - The invention allows the use of a rotor position sensor (32) with "digital" output signals, that is to say signals which jump between only two values. <IMAGE>

Title: Guiding and braking carriage for an unfolding mechanism of a drilling and production platform
Inventor: ISENBERG WILHELM DIPL ING
IPC: E02B17/02
Filed: 1983-01-28
Abstract: For the unfolding step in the case of a tripod of a drilling and/or production platform, two of the standing legs 1a and 1b are held in a floating position, while the third standing leg 1c is lowered, guided by a tie-bar 4 articulated to the standing legs 1a, 1b, by means of a rope pull 5. The articulation of standing leg 1c to the tie-bar 4 is effected by means of guiding and braking carriages 8a and 8b. For controlled lowering, these are integrated with disc brakes 20 which interact with a guide rail 9a and 9b, along which the guiding and braking carriage 8a or 8b is displaced relative to the tie-bar 4. The rotation superposed on the displacement is taken up by the first or second sliding pieces 16a and 16b or 17a and 17b, the sliding pieces being connected to the standing leg 1c. A connection, which can be rotated out but is secured against linear relative motions of the guiding and braking carriage 8a or 8b and of the standing leg 1c, is made by these sliding pieces. <IMAGE>

Title: Device for sorting crown tops or similar small components as a function of their correct or incorrect lateral position
Inventor: BAER KARL-HEINZ
IPC: B65G47/256
Filed: 1983-07-16
Abstract: In a sorting device 10 for crown tops 11 with a deflector 14 for separately leading off crown tops 11 running on the base side or crown edge side in a feed shaft 12 in close succession, there is the risk, due to the deflection of the crown tops 11 at the deflector tongues that two crown tops 11 which are fed with their sides in the incorrect position will hook onto one another and block the device. This is avoided according to the invention in that in front of the deflector 14 the feed shaft 12' is guided in an arcuate shape about a part of the circumference of a separation wheel 13, which is driven by a motor at high speed, for the crown tops 11. This separation wheel 13 has on its circumference permanent magnets 22 which attract the crown tops 11 and bring about spacing between the crown tops 11 in front of the deflector 14. <IMAGE>
