Steel is made from solid additive material by charging the solid material (28) into the arc furnace and melting using electrodes (19 to 21). Fuel-oxygen burners (23,24,25), located between the electrodes and enter the furnace from the side, are used to cut areas in the solid material where oxygen lances (29 to 34) are inserted. These lances are directed to flow oxygen onto the surface of the melt....

This new method processes the components of composites, comprising solid organic and/or inorganic composite materials. These may include composites of metals, plastics and/or minerals. Particles are formed from the composite and added to a transport fluid. Relative to the flow of this mixture, a flow obstruction crosses transversely, causing turbulence. Motion causing acceleration and separation i...

The X-ray imaging system uses a patient bed incorporating an X-ray detector (4), with a matrix of detector elements, incorporated in the mattress (3) or the underlying support surface (2). The X-ray detector is coupled to an electronic image processing unit (6), pref. mounted beneath the bed, with a plug socket for connection to an X-ray image monitor (7).

By means of the device, portions of a paper or film web 14 are inserted between the food slices. The cutting apparatus with the knife 11 is controlled by a step motor which is started by the cutting machine cutting the slices. The triggering pulse of a further step motor, which drives the paper feed 4, is derived from the position of the cutting apparatus. A uniformly driven conveyor belt 6 extend...

A glass fiber separator material is disclosed. The separator is composed of a mass of intermeshed glass fibers substantially all of which have a fiber diameter not greater than about 20 .mu.m, and at least 5 percent w/w of which have a fiber diameter less than 1 .mu.m, and, distributed through the glass fibers, and from 0.2 percent w/w to 20 percent w/w of cellulose fibrils. The fibrils are from a...

Dense star polymers or dendrimers, modified by capping with a hydrophobic group capable of providing a hydrophobic outer shell, act as molecular nucleating agents in forming a polymer blend.

In a method for drilling adjacent to a cased known first borehole a second borehole in a predetermined direction the following steps are carried out for a number of along hole depths di: measuring components of gravity acceleration and magnetic field (earth & casing); determining direction parameters alpha i; deriving magnetic polestrength components, Bp1,i and Bp2,i; applying Bp1,i/Bp2,i=s1,i/s2...

Mit der Erfindung wird der Eintrag und das Löschen von Belegungsgradwerten in zellular strukturierten Umgebungskarten von autonomen mobilen Einheiten verbessert. Für jede Zelle der zellular strukturierten Umgebungskarte werden in Abhängigkeit der Messrichtungen von Ultraschallsensoren unterschiedliche Sektoren definiert, in welchen die Belegungsgradwerte separat erhöht werden können. Dies hat den ...

A docking system (1) which essentially comprises at least one docking station (2) for at least one self-propelled working tool (3), and includes the working tool (3) itself, preferably intended for attendance of ground or floor, such as grass-cutting, moss-scratching, watering, vacuum-cleaning, polishing etc. The docking station and the tool can by way of emitted signals establish contact with eac...

A puncture preventive sealant is capable of reducing the content of cellulose fibers for suppressing the cost of the sealant while keeping a high sealing performance due to the cellulose fibers. A sealant 8, which is filled in a sealant chamber 7 defined in a tube 2 adjacently to an air chamber 3, contains synthetic fibers and cellulose fibers in a solvent. The content of the synthetic fibers is i...

This invention provides oligomer-free polyesters that consist essentially of repeating, interpolymerized units derived from isophthalic acid and/or terephthalic acid, and 9,9-bis-(4-hydroxyphenyl)-fluorene, a process for making such polyesters and articles comprising said polyesters such as electrical capacitors, optical films and fibers.

A pallet is made from corrugated cardboard which is cut and creased and scored and folded so as to form a series of base members each having a solid core of vertically extending panels with vertically extending corrugations, wrapped by perimetric extending panels. A series of deck members are formed likewise, and interlocked with the base members using cut-outs in the panels from which the members...

A magneto-optical recording device has a flying head (11) that floats over a magneto-optical disk according to the rotation of the magneto-optical disk. The flying head includes a head slider. A solid lubricant (13) is applied to the bottom surface of the head slider facing the magneto-optical disk. Since the solid lubricant makes the flying head contact with the magneto-optical disk smoothly, the...

A semiconductor device accommodated in a package includes a semiconductor chip (35), a package body (32) for accommodating the semiconductor chip, and a plurality of terminal members (33) embedded in the package body in electrical connection to the semiconductor chip and projecting from a bottom surface of the package body, wherein each of said terminal members has a shape such that the terminal m...

A bonding liquid dispersion comprising polyvinyl acetate, mixed stabilisers, a coalescing agent and polyvinyl alcohol which complies with British Standards 5270 and 4071 and is preferably water resistant. This dispersion can be used to strengthen gypsum plaster, cement and wood adhesive compositions and improve water and creep resistance. A process for preparing such a bonding liquid is also descr...

A route searching apparatus finds the optimal route between 2 points on a road map by searching on a first hierarchical level for a main road using a first cost-function (favouring e.g. wide roads) and subsequently searching on a second or even third hierarchical level for routes connecting the start and end points to the main road using second or third cost-functions (favouring e.g. shorter drivi...
