In the course of a process for the direct reduction of iron ore or iron oxide pellets to give sponge iron in a reduction furnace (1), hot reduction gas is injected through a reduction-gas inlet (4), the gas flowing upwards through the descending charge, reducing the iron ore or the iron oxide pellets in the process and being drawn off as top gas through a top-gas outlet (5). In a cooling zone (9) ...

Process for the treatment of yarns on their run to at least one bobbin or to a warp or yarn beam. There is applied to the yarn or yarns a flowable anti-adhesive, by means of which the mutual adhesion of the yarn turns adjacent to one another on the bobbin or beam is reduced or prevented. For applying the anti-adhesive to the yarn or yarns, there is used at least one applicator roller, through the ...

A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantia...

CONSTITUTION:The unmanned carrier 1 is equipped with the transport device 3 for works 18 at the upper part of a carriage 2 and also has a co...

PURPOSE:To allow the titled unmanned carriage to perform more different operations by using a bar code formed of reflecting material for ground station information with which the unmanned carriage is reduced in speed and stopped. CONSTITUTION:A detection part 2 is fixed to the bottom front part of the unmanned carriage 1 and an arithmetic circuit 3 and a driving part 4 are incorporated. Said detec...

Textile reinforcement for use in making layered complexes, the reinforcement consisting of lengthwise yarns 2 and crosswise yarns 1a, 1b. The different sheets are joined by means of additional lengthwise yarns 3 which run through the accumulated layers and around the outer layers, the said joining yarns being based on a heat-meltable substance.

The diathermy electrode comprises a flexible insulating guide tube (1) in which a flexible electrode lead (3) adapted to be connected to a diathermy current source is slidably displaceably disposed. Attached to the free end of the electrode lead (3) next to the patient is a resilient electrode snare (5) which is capable of resiliently spreading apart when slidably moved out of the guide tube (1) a...

In floating-caliper disc brakes, the friction in the caliper guides hinder movement of the caliper in the brake release direction, thus, increasing the drag of the brake when it is not operated. According to the present invention, the reaction portion of the caliper is provided with an applying piston of small axial length whose axial movement is limited to an amount equal to the required brake cl...

PURPOSE:Preparation of a granulated compounding additive for vinyl chloride resins, which is easily handled, and has no tackiness even at a high concentration of addivives, e.g. plasticizer, etc.

In a process for the production of mouldings from cellulose-containing fibres which are dry-mixed with thermoplastic binders and at least one thermoset binder in powder form, scattered to give a nonwoven and precompacted at elevated temperature to give a transportable mat, which is in turn pressed at elevated temperature to give the moulding, it is proposed, in order to improve the compressive str...

Apparatus for the manufacture of metal powder by atomization with noble gas or nitrogen, having an atomization tower, a gas recycling system, and a gas cleaning system is disclosed. The gas cleaning system is connected parallel to the atomization tower in order to shorten the start-up time without increasing the cost and complexity of the gas cleaning system.

The invention relates to a process for pretreating natural fibres and producing synthetic organic fibres, which are used for refractory materials with or without added binders and fillers. The fibres are impregnated with oxygen compounds of manganese(IV) and/or of chromium(VI) or - in the case of synthetic fibres, produced with these compounds added. Fibres pretreated in this way are used for prod...

A data processing and communication system distributes and displays financial market ticker, quotation, news and ancillary information via a plurality of stored program controlled work stations. Stock trade executions, quotations and other ticker plant information is communicated in parallel to a hierarchy of system data processing terminals, e.g., those located at area, branch and individual work...

A way of placing chokes with air core, such as thyristor commutating chokes, in a three-phase alternating current rectifier. With a view to eliminating the drawbacks of air-core chokes especially in three-phase rectifying applications, the three chokes of three phases, wound in the same winding direction, are placed on one and the same plane at the corner points of an imagined triangle which bring...

The invention provides a water-reducible coating composition comprising an epoxy resin, an amino group-containing curing agent for the epoxy resin and a watersoluble organic compound which occurs in at least 2 tautomeric forms, in one of which a labile hydrogen atom is linked to a carbon atom and which compound contains at least one carbonyloxy group or sulfonyl group.
