Title: Dispensing device for a plurality of flowable material components
Inventor: EMELE EDGAR F
IPC: B65D81/32
Filed: 1984-05-30
Abstract: A closure cap (22) which acts as a valve body is displaceable on a nozzle (8) between at least two different axial positions and contains dispensing apertures (50). The nozzle (8) is fitted with closure elements (48) which close the dispensing apertures (50) of the closure cap (22) in one position thereof and, in its other position, expose a flow connection between the dispensing apertures (50) and the dispensing channels (10, 12) of the nozzle (8). A partition (16) of the nozzle (8) which separates the dispensing channels (10, 12) from one another extends in the axial direction beyond the nozzle (8) into a slot of the closure cap (22) to the extent that no flow connection is produced between the delivery channels (10, 12) of different chambers (4, 6) inside the closure cap (22) in any axial position of the closure cap (22). As a result, the material components of the chambers (4, 6) cannot become mixed with one another and react with one another inside the cap (22). The dispensing apertures (50) can be closed and opened as often as desired. As a result, the material components do not need to be used up at once or the remainder thrown away, but the use of the material components can be interrupted several times. <IMAGE>

Title: Frequency generator with raised oscillating circuit voltage
Inventor: GAERTNER WERNER DIPL ING
IPC: H02M7/48
Filed: 1985-11-19
Abstract: The invention includes a circuit with which it is possible to double the supplied voltage to a frequency generator in single-phase operation with a parallel oscillating circuit, so that considerably higher useful power can be achieved with one and the same transistor with a specified maximum permitted drain or collector voltage. The oscillating circuit voltage, which in normal operation rises to twice the supplied voltage, and for which the transistor must be designed in relation to its electric strength, has its top half-wave cut off by a gate cut-off thyristor, which is connected in the supply line between the oscillating circuit and the transistor, so that the transistor is loaded, in terms of voltage, with the supplied voltage only. The positive half-wave then lies on the thyristor, which during C operation of the generator is only switched on and off in the current-free state.

Title: Circuit arrangement for resolving operand conflicts in data processing systems which work on the assembly line principle
Inventor: BETHMANN JUERGEN
IPC: G06F9/38
Filed: 1986-02-03
Abstract: If a conflict occurs, the command preparation processor (PLU) and command execution processor (EXU) are each halted for one operation cycle only. To prepare for the micro-commands which are to be executed in the normal way, the command execution processor (EXU) then reads the required memory operands itself, using the operand addresses which have been communicated to it, while the command preparation processor (PLU) continues to operate without hindrance. The cost is lowest if only one operand for a single command of restricted length, e.g. eight bytes, is read in advance, and the addresses of the first and last operand bytes are compared with the possible write address of the command execution processor. <IMAGE>
Patent DE-3610218-A1 (DE)
Title: Composite material and process for the production thereof
Inventor: POSTULKA SIMON DIPL CHEM DR
IPC: B32B3/08
Filed: 1986-03-26
Abstract: A plurality of processes are already known for producing a metal coating on a plastic substrate material. Using these, however, only relatively thin metal layers can be applied to plastic, and only with limited adhesion of the metal layer to the plastic substrate material. Since such a coating does not always fulfil the high technical requirements, these disadvantages are to be compensated by the invention. In the composite material according to the invention, therefore, it is provided to apply the plastic substrate material subsequently directly onto the metal layer having a residual roughness.

Title: Control device for increasing wheel contact pressure in multi-wheel road vehicles
Inventor: BAUN HANS ULRICH DIPL ING
IPC: B60B39/00
Filed: 1986-03-27
Abstract: Control device for improving the grip in multi-wheel road vehicles by increasing the respective wheel contact pressure, in particular on an extremely slippery carriageway, as a result of an electronically controlled, but for example hydrodynamically, electromagnetically or electromotively operating system superimposing medium-frequency or high-frequency vertical oscillations on the rotational motion of each rolling wheel, simultaneously or in accordance with a predetermined programme, and thus, as a result of the downward acceleration of the said vibration, increasing the contact pressure of the tyre/carriageway friction in such a way that, for example on black ice, a shorter braking distance, and increased starting-up torque and, generally, an improved grip is obtained.
Patent DE-3611475-A1 (DE)
Title: Simultaneous SO2 and NOx separation in flue gases downstream of combustion plants
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-04-05
Abstract: It is known to reduce SO2 and NOx in flue gases by scrubber solutions in scrubbers. For this purpose, EDTA-iron complex compounds are used in preferably alkaline scrubbing solutions. In this case intense oxidation of iron(II) to iron(III) is produced by the high atmospheric oxygen content in the flue gas. In order to carry out the reduction from iron(III) to iron(II), reducing agents or electrolytic processes are used. In order to decrease the necessary reducing agent consumption or to avoid the use of electrolysis, according to the invention it is proposed that the scrubbing fluid enriched with EDTA-iron complexes, after contacting with the untreated gas in the scrubber, is stored in a delay vessel having a residence time greater than one hour. The length of the residence time depends on the proportion of the iron (III) to be reduced to iron (II) in the scrubbing fluid.

Patent DE-3625129-A1 (DE)
Title: Shaft lining with cast-iron ring elements for deep freezing shafts in mining
Inventor: LUETGENDORF HANS-OTTO PROF DR
IPC: E21D5/012
Filed: 1986-07-25
Abstract: In a shaft lining for the support of shafts sunk by the freezing method in unstable water-bearing rock, a water-permeable outer lining cylinder absorbs the rock pressure. Located between the outer lining cylinder and an inner lining cylinder is a sliding layer of asphalt, the specific gravity of which only slightly exceeds the specific gravity of water. The inner lining cylinder possesses a watertight steel casing as an inner delimitation relative to the asphalt layer and a ring column located inside the steel casing and consisting of a plurality of supporting rings stacked one above the other. Since only compressive, shearing and bending-pressure stresses have to be absorbed by the ring column of the inner lining cylinder, at great depths the support rings consist of cast-iron ring segments which have a H-shaped, that is to say approximately dumbbell-shaped profile. The horizontal webs have casting holes, through which filling concrete is poured into the interspace between two adjacent supporting rings. The cast-iron ring segments can consist of a cheap grade of cast iron. Such an inner lining cylinder is substantially more advantageous than a lining cylinder in which the supporting rings consist of composite reinforced-concrete rings, because, at greater depth, these composite rings must have very large thicknesses in order to be capable of withstanding the loads. <IMAGE>
