In a power plant which includes a gas turbine unit and a steam turbine unit which units are supplied with gas and steam, respectively, from a common combustion chamber 1, 2 in which combustion takes place under pressure in a fluidized bed 3, the units of the plant are designed to operate efficiently with each other at an ambient temperature (To), which is usually about +30 DEG C. To enable the pla...

The metering of the yarn (14) which is drawn off and is to be wound onto spools (15) is carried out at each work unit (5) of the machine by means of a pulse counter (2), in which pulse counters (2) periodic pulses are transmitted (during active operation of the work unit) by a central system (1) which has an independent pulse transmitter (11) and an actuating element (16) for preselection of the c...

In a process for operating a vertical moving-bed reduction reactor for reducing iron ore to sponge iron, having a reduction zone in the upper part of the reactor and a cooling zone in the lower part of the reactor, the desired degree of metallisation of the reducing ore is obtained in the reduction zone and the desired degree of cementation is obtained in the cooling zone, the process being charac...

This valve magnet, designed for direct current, has a casing with pole plates at the ends, an electric coil, a core, a guide tube which adjoins the core and in which an armature is supported in axially movable fashion, and a cap which closes the guide tube and has a manually operated emergency pin. The manually operated emergency pin is designed in such a way that it can be pushed into a hole in t...

A navigation apparatus for vehicles, having an input unit (1) for entering input data, by means of which a specified destination can be entered with its destination coordinates relative to the starting point of the vehicle and can be evaluated to produce a destination vector. Furthermore, there is an output device which can indicate the instantaneous destination vector valid in each case in terms ...

A yarn splicing device for spun yarns, wherein extremities of ends of the yarns which are inserted in overlapping and oppositely directed relationship in a yarn splicing hole are acted upon by flows of a fluid turning to be spliced with each other. The yarn splicing hole is substantially divided in an axial direction thereof into two yarn splicing holes which have center axes displaced from each o...

It is known to apply coatings which have desired characteristics, e.g., wear resistance, thermal barrier capabilities anti-oxidation, to articles the material of which does not have the desired characteristic, wherein the coating is applied directly to the article. Some article materials, e.g. titanium are highly reactive which immediately obviates several known methods of applying coatings. The i...

A method and apparatus for automatically removing a weld upset formed between a pair of coaxial workpieces butt welded into an integral article by friction welding or the like. The method and apparatus include a shearing device positioned closely adjacent the abutting surfaces of the workpieces during welding and automatically drawn through the weld upset upon completion of welding to remove the u...

A radial tire carcass fabricated by a first stage process has bead portions which are placed over a pair of spaced-apart coaxial bead seats. The bead seats may be segmented radially expandable rings which are expanded by fluid pressure into engagement with the bead portions. The tire carcass is initially positioned on the drum with the bead seats at a spaced-apart distance so that upon expansion o...

Thermoplastic polystyrene laminates are disclosed, one of the layers of which comprises a filled polystyrene composition containing from about 5 to about 50 of filler, such as calcium carbonate, clay, asbestos, etc. The filled polystyrene composition is prepared from a filled polystyrene masterbatch of impact polystyrene, filler, rubber and mineral oil, cut back by mixing with other polystyrene, e...

Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into a precipitating solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized. The beads may a...

A pair of opposing pistons 4, 8, which are connected to the shoes (not shown) to apply braking pressure thereto, are slidingly accommodated in a fixed cylinder 1 connected to a hydraulic braking circuit. A spacer member 17, 18 is connected between the pistons 4, 8, and when the pistons move apart by a distance greater than the spacing between stop rung 21 and spigot 16, due to wear of the linings ...

The invention relates to a process for preparing cold-hardening foams containing urethane groups using as an emulsifier, sulphonamide compounds of the formula: wherein R represents an alkyl, chloroalkyl, cycloalkyl radical having from 8 to 30 carbon atoms, or an alkaryl radical having from 10 to 30 carbon atoms, R1 and R2, which may be the same or different, each represent a hydrogen a...
