Title: Desulphurisation of petroleum coke produced by delayed coking
Inventor: KAPNER ROBERT S
IPC: C10L9/02
Filed: 1983-07-14
Abstract: Coke produced by delayed coking is desulphurised by contacting the coke initially with a gas containing active sulphur, at a temperature which is high enough to cause a reaction between the sulphur in the coke and the active sulphur in the gas and then holding the coke in contact with the gas for about 1 hour at the high temperature. An alternative process allows desulphurisation of coke produced by delayed coking, with modification of the second stage of the first process, the sulphur-containing gas being diluted or replaced by an inert gas. In a third alternative, the above process is further modified by lowering the temperature during the second stage or delay stage, in order to maintain the reaction between the sulphur-containing gas and the coke.

Abstract: Method for the perennial mass propagation of annual useful plants using the shoot primordium, characterised in that the tip of shoots of the annual useful plants is excised, the excised shoot tip is transplanted into an artificial nutrient medium which contains a mixture of inorganic salts and a plant growth hormone, the shoot tips are subjected to a rotation culture at a temperature of 15-30 DEG C and an irradiation intensity of 2000-9000 Lux while maintaining a rotation speed of 0.5-10 rotations/minute, thus multiplying the shoot primordium, and the resulting shoot primordia are subjected to a stationary culture for the formation of young plants. Within a short time, the annual useful plants can be subjected to a multi-year perennial mass propagation while maintaining the genotype and the chromosomal type. This method is particularly effective in the propagation of triploid water melons, hybrid maize, hybride rice plants and convolvulus hybrids.
Patent DE-3402562-A1 (DE)
Title: Magnetometer for measuring weak earth magnetic fields and for measuring the difference between earth magnetic anomalies due to geology and due to technology
Inventor: MERSMANN LUDGER
IPC: G01V3/40
Filed: 1984-01-26
Abstract: When measuring earth magnetic anomalies, it is important to distinguish whether an earth magnetic anomaly has technical or geological causes. Previous magnetometers were not able to measure this difference which was of disadvantage, in particular, in the case of measurements of the earth magnetic field and its anomalies within a built-up residential area because there is a difference in the biological effects between the earth magnetic anomalies with technical causes and those with geological causes. According to the invention, the difference is measured by electronically connecting a metal detector to the magnetometer which controls the measurement value indication of the magnetic field measuring instrument as a function of the presence of a metal having earth magnetic effects or of the non-presence of a metal. It can also be used in treasure hunting or in mine clearance or in marking surveying points which can be mounted below ground by means of magnetic or metallic marking metals and can be made locatable again by measurements by means of a specific magnetometer.

Inventor: NATTERER JOHANN
IPC: B65B51/10
Filed: 1984-03-30
Abstract: Process for packaging objects wherein a cavity is formed from a sheet, the object to be packaged is introduced in the cavity, a cover is applied to the cavity, the pressure is lowered in the inner space of the cavity and in the outer space surrounding the cavity on its lower side and the cavity is closed with the cover by welding, respectively sealing. In order to avoid an expansion of the object to be packaged during the vacuum operation, a pressure difference is created when a first predetermined pressure is reached in the outer space, between the inner space pressure and that of the outer space so that the cavity is applied against the object to be packaged under the effect of the pressure difference. To this effect, there is provided a device (44, 45, 46) to produce a pressure difference between a higher chamber (11) and a lower chamber (17) of a vacuum and sealing station, as well as a control (37) which is intended to actuate the device (44, 45, 46) upon reaching the first predetermined pressure value in the lower chamber (17).

Patent DE-3415419-A1 (DE)
Inventor: BERCHTOLD NIKLAUS
IPC: G01B7/34
Filed: 1984-04-25
Abstract: The feeler in the tooth flank profile measuring apparatus for determining the roughness of the tooth flank surface comprises a Hall-effect sensor placed in a static magnetic field between two permanent magnets instead of the otherwise conventional piezo-electric or inductive measuring system. One of the two permanent magnets is adjustably mounted at one end of a feeler rod or arm which carries at its other end a feeler tip for scanning the tooth flank surface. A conventional cross-spring joint serves to rotationally mount the feeler rod or arm. The cross-spring joint need not be distorted or loaded for adjusting the bearing load of the feeler tip because there is provided for this purpose a magnetic bearing load adjustment device. The magnetic bearing load adjustment device not only compensates for the biasing force of the two permanent magnets of the measuring system, but generates a selectable bearing load for the feeler tip by overcompensating for the biasing force of the permanent magnets of the measuring system. This selectable bearing load for the feeler tip can be already measured during the adjusting operation. Since this bearing load is generated by the magnetic fields and since the cross-spring joint need not be distorted, the feeler has a substantially greater mobility and a substantially wider frequency response compared to known feelers. The feeler additionally has a simpler mechanical structure and the circuitry in the evaluation circuit is substantially less complicated in comparison to known feeler arrangements.

Patent DE-3422529-A1 (DE)
Title: Winding machine
Inventor: SCHIPPERS HEINZ DR DR
IPC: B65H54/28
Filed: 1984-06-16
Abstract: In a winding machine for winding continuously arriving yarns onto cross-wound bobbins, a double traverse is employed. The traverse consists of a grooved roller which directly precedes the bobbin. Grooves are cut into the grooved roller and can have a differing depth. The traversing device which is the first in the yarn run consists of oppositely rotating vane wheels which, together with a guide rule, bring about a preliminary control of the yarn movement. The law of movement of the pre-traverse stipulates, in the regions of stroke reversal, that the traversing stroke of the grooved roller is covered and then a return movement at increased speed takes place in the event of extreme deceleration and acceleration.

Title: Horizontal deflection circuit
Inventor: SCHULZ HARTMUT DIPL ING
IPC: H03K4/62
Filed: 1984-08-16
Abstract: Horizontal deflection circuits are known in which, for switching the deflection current, two transistors are connected in series so that the power dissipation and also the retrace voltage is distributed to two transistors. In the known circuits, the transistors drive primary windings of a line transformer, to the secondary windings of which the deflection coils are connected. With the present invention, a horizontal deflection circuit is to be created which is suitable for television display devices having a high line frequency but in which, nevertheless, commercially available switching transistors, a commercially available line transformer and a set of deflection coils are used, the horizontal coil of which is provided with only two connections. For this purpose, two switching transistors (TS1, TS2) are connected in series, in parallel with which two series-connected capacitors (C1, C2) are connected for distributing the retrace pulses, the junction of the transistors and that of the capacitors being connected to one another with respect to alternating current. The collector of the transistor (TS1) at the higher potential is connected, on the one hand, to the primary winding (W11) of the line transformer (T1) and, on the other hand, to the horizontal deflection coils (HL) via a tangent circuit and an east-west correction circuit (C4, L1 and, respectively, OW). The main field of application comprises television display devices with a large line number. <IMAGE>
