Title: Method for carrying out a linear reciprocating stroke of an object which is loaded on one side, and a device for carrying out the method
Inventor: FLAAM ELMAR
IPC: H01F7/16
Filed: 1984-12-29
Abstract: For a linear reciprocating stroke of an object which is loaded at one side, said object is opposed by an opposing force in a sprung composite device, which is relieved of stress during the stroke movement against the load on one side and is stressed during the stroke movement in the direction of the load on one side. In this case, the forces (which in each case change in an opposing manner) of the sprung composite device, and the load on one side on a magnetic armature of a reversing solenoid are used, and the opposing force is dimensioned such that it corresponds to the load on one side and holds the magnetic armature in the excitation-free state in a central position in the reversing solenoid. In this case, the movable magnetic armature (7) in a reversing solenoid (1) is mechanically connected to an object (21) which is to be driven and is loaded on one side, and a spring arrangement (25) is provided on the magnetic armature (7) as the sprung composite device, which spring arrangement (25) is prestressed with respect to the object to be driven and holds said object in a central position. <IMAGE>

Title: Multi-stage catalytic process for converting heavy hydrocarbon liquid charges
Inventor: NONGBRI GOVANON
IPC: C10G65/02
Filed: 1985-01-10
Abstract: In a process for the hydroconversion in good yield of heavy liquid hydrocarbons such as, for example, petroleum residue charges which contain at least about 25% by volume of material boiling above about 520 DEG C<+)<975 DEG F<+>), using multi-stage catalytic reactions at elevated temperature and pressure to produce increased yields of lower-boiling hydrocarbon liquids and hydrocarbon gas, the charge is fed in the liquid phase with hydrogen under elevated temperature and pressure conditions into a staged catalyst reactor system preferably containing catalytic fluidised beds, from which a vacuum bottom fraction having a nominal boiling point above about 430 DEG C(800 DEG F) is recycled to the reactor of the last stage and not to that of the first stage, in order to improve the conversion of the 520 DEG C<+)<975 DEG F<+>) fraction to lower-boiling liquid products. If desired, three stages of the catalytic reaction can be used, the vacuum bottom material fraction being recycled to the third-stage reactor.

Title: Rotating mechanical seal
Inventor: SADE MANFRED
IPC: F16J15/34
Filed: 1985-03-06
Abstract: In order to be able to seal off the interior of a machine housing, in particular a pump, mixer, stirrer or screw housing, liquid-tightly and/or gas-tightly from the atmosphere in the region where the shaft passes through, various designs of rotating mechanical seal systems with internal and external, pressure-relieved or pressurised seals and seals with internal or external supporting bearings have been developed and used. A disadvantage with these sealing systems is, however, that they are constructed in such a way that they are not interchangeable, even where the shaft diameter is the same. However, according to the invention, free interchangeability of such sealing systems is achieved in a simple manner by a special design of the gland (1) as a universal gland of a rotating mechanical seal, the gland (1) being provided on the inside with recesses (7), such that sealing systems of different designs can be inserted interchangeably in these recesses (7) and in the extension (6), for example the stuffing-box space, of the housing (2), the interchangeable sealing system preferably being arranged on a collet (11) surrounding the shaft (5). <IMAGE>

Title: Corncob picker with chopper
Inventor: OSTRUP HEINRICH DIPL ING
IPC: A01D45/02
Filed: 1985-04-27
Abstract: The present invention relates to a corncob picker with a plurality of pairs of picking rollers, each pair of picking rollers being assigned a chopper. These choppers are mounted drivably at a distance from one another on a common shaft and are covered upwards by a fixed hood part. So that a uniform distribution of the chopped material can be achieved over the entire machine width, each chopper is assigned a guide plate, the height of which can be adjusted separately, each guide plate being equipped with two distributor plates which point vertically towards the ground and which can be adjusted independently of one another in their angular position relative to one another. In this way, it is possible, even under the most diverse harvesting conditions, to carry out an adjustment which allows the chopped material to be distributed uniformly on the field over the entire width of the machine.

Title: Arrangement for cooling electronic components
Inventor: GUMBSHEIMER RAINER
IPC: H05K3/28
Filed: 1985-08-07
Abstract: It is difficult to define the necessary cooling power for a large electronic system with sufficient accuracy, as the compact construction which is aimed for in modern devices demands. The dissipated power of electronic components is known, but only the power parts which are directly provided with heat sinks can be effectively and calculably cooled. For this reason, the cooling system is usually over-dimensioned, which has many disadvantages. However, the space required for the cooling units, and the noise level, can no longer be ignored in large systems. The arrangement according to the invention for cooling electronic components 2 which are fitted to boards 1 makes it possible to conduct away dissipated heat from all components 2, differentially and predictably. Bulk material 11 transfers the heat from the components 2 to the heat sinks 4, 5 by the shortest route, and enables the cooling system to be more effectively used. <IMAGE>

Title: High or low pressure fuel vaporiser for improved use of the fuel in combustion engines
Inventor: SCHIESSL FRANZ
IPC: F02M31/18
Filed: 1986-08-28
Abstract: In certain combustion engines, previously atomised fuel is forced into cylinders, filled with compressed air, and ignited. The said fuel vaporiser improves the existing type of fuel feed in that the fuel is converted into vapour before it is fed into the cylinders either in that the fuel fed in is ignited and the resulting flame gives rise to a further fuel feed for vaporisation, or in that electrical heating causes the vaporisation until suitable heat is produced inside the engine block by engine starting in order to introduce the further fuel feed for vaporisation, so that the heating is abandoned and switched off. After switching off the engine, the residual fuel vapour existing and still being produced is led back into the fuel feed and condensed. A tensioning spring in an associated switch gear may replace or boost an existing control weight and thereby improve an operating function as required.

Patent DE-3634622-A1 (DE)
Inventor: FROHN WALTER DR ING
IPC: B05B15/555
Filed: 1986-10-10
Abstract: In order to clean objects, in particular paint spray guns, with a liquid cleansing agent, the parts are introduced into a basket (44) rotatively mounted around a vertical axis within an airtight cleaning chamber (44). A pump (84) driven by a compressed-air motor (86) sprays the cleansing agent through spraying nozzles (67, 69) on the parts to be cleaned, thus rotating the basket. The spray gun bodies held in supports in the basket (56) are rinsed with cleansing agent sprayed through their paint inlets and supplied by a branch pipe (58) and adapter (72a, 72b) arranged across the axis of the basket. The used cleansing agent is returned through a filter (42) to a container (36). Another container (34) contains unused cleansing agent. For a first, rough cleaning, the pump (84) supplies used, filtered cleansing agent. For the final cleansing the unused cleansing agent is supplied. After the final cleaning, compressed air is blown into the cleaning chamber (44) and at the same time the air containing cleaning agent vapours is extracted from the cleaning chamber (44) through a venting nozzle (46) by a compressed-air injector (112). The process is automatically controlled, if necessary with a full cleaning option and a rough cleaning option followed by drying.

Title: Process and means for filling undesired cavities and cracks during the production of composite screed, supports, joists, prefabricated compound units, etc., consisting of concrete
Inventor: RIECK WOLFGANG
IPC: E04F15/12
Filed: 1986-12-16
Abstract: During the production of screed and other structural parts consisting of concrete, cavities and cracks, which do not ensure 100% strength, often occur in the structural parts. Processes for filling such cracks, etc., the latter being filled by means of resin from the outside via dowels, produce unreliable results, are very expensive and cause a lot of dirt due to the resin.   The disadvantages are eliminated by the introduction of a plastic hose into the part which is to be concreted, which hose is perforated and permits synthetic resin to be guided, by means of a pump, from the inside to hollow locations and cracks in the structural part in order to close up the latter, without harmful dust particles, air, etc. being able to penetrate during this sealing. The cracks which are visible from the outside (visible cracks) are closed off by a sealing composition which is removed again after the seal has hardened. In this arrangement, there is no dirt and no follow-up work.
