Ceramic material for use in heating installations of all branches of technology as a heat-storing material or wear material with the aim of economically exploiting secondary raw materials containing iron oxide and at the same time generating savings in materials and energy as well as a decrease in the aggregates, while retaining a chemical resistance in the furnaces. The subject lies in the develo...

Apparatus for loading rows of containers onto a loading station in which the containers are pushed onto the loading station in rows, preferably with the containers in adjacent rows being staggered relative to one another, the leading container row engages a wall which substantially uniformly frictionally resists the movement of rows onto the loading station, and in which side walls which supportin...

In a multiple computer system, one computer outputs a program, to which a coding giving its characteristics, e.g. the content and length of the program, the co-operation with other programs, the contents of the input and output data of the program, is attached, to a transmission line. Another computer tests the program on the basis of the coding which gives the program characteristics, and accepts...

A filter pack comprises a first housing member (1) having an inlet port and an outlet port (4) for compressed air; the outlet port being connectable to a piece of equipment, for example a spray gun. A second housing member (6) is removably fitted into the first housing member through an opening (5) therein and has a section (8) protruding from the opening. A retaining ring (12) releasably secures ...

A homogeneous refractory composition comprises 100 parts by weight basic refractory aggregate and 0.02 to 20 parts by weight of a water-insoluble or sparingly-soluble phosphate.

What is disclosed are food compositions for human consumption which contain from 0.1 to 100 weight percent of certain polyorganosiloxanes. An example of such a food composition is a blueberry muffin prepared by substituting a polyorganosiloxane having the formula (CH3)2SiO[(CH3)2SiO]bSi(CH3)3 for the fats and oils in the blueberry muffin batter mix.

There is provided a lapping arrangement with circulating thread guides for a warp knitting machine. The arrangement has carriers for the thread guides. A transport arrangement moves the carriers in a guide means comprising two parallel segments connected by two turning segments. In the location of the parallel segments the transport arrangement comprises two forwarding helices in whose helical thr...

There is provided a warp knitting machine for diagonally laying warp threads with thread guides that circulate around a continuous pathway. The warp threads are taken from spools located on a fixed creel and are led through a fixed thread feed arrangement located above the circulating path. The frame is rotatable about a perpendicular turning axis in a direction opposite to the direction of rotati...

2-(N-Formylamino)-propionitrile is prepared by reacting acrylonitrile with formamide in the presence of a basic compound by a process in which the basic compound used is a tertiary nitrogen base.

A method for the production of a preform blank for optical fibres, which has a core and an outer jacket of fused silica or doped fused silica, which incorporates the following process stages: preparing a tube (1) as an outer fused silica jacket; inserting at least one porous or loose material element (2) into the fused silica tube; connecting the extremities (4, 6) of the fused silica jacket tube ...

An object is produced from a tubular blank (10,15,17) of thermoplastic material of polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one or several consecutive re-shaping operations. A mechanical shaping device (23,29,71,81) moves a transitional zone (13,14,113) situated between thicker ...

Improved operation of the broadly known combination of a moving bed, gaseous reduction reactor for reducing iron ore and a melter-gasifier for converting to molten metal the sponge iron pellets produced in such a reactor is achieved by preparing a mixture of finely ground sponge iron and coal, either by mixing the sponge iron and coal and then grinding or by separately grinding the sponge iron and...

A water-jet drive mechanism for driving and controlling a watercraft includes a substantially cylindrical support housing which is supported for rotational movement about a substantially vertical pivot axis in a cylindrical recess in the undersurface of the watercraft, with its undersurface flush with that of the watercraft. A centrifugal water pump is encased in the support housing so that its in...

To lower the resonant frequency of a loudspeaker box equipped with loudspeakers, a bass with its own housing is mounted on the inside and supplied with low-frequency sound vibrations or infrasound noise which is sufficiently damped in the audible range, the fundamental sound wave length of which can be several kilometres; matched to the original resonant frequency and phase radiation. To achieve a...

In a shaped hose branching, especially a radiator hose for a motor vehicle, having a branching tube piece (1) of metal or plastic, to whose free tube connecting pieces (2,3,4) there are connected vulcanised hose ends (10) by means of a mass which can be vulcanised, in order to increase the strength, and in particular for better absorption of repetitive stresses, it is provided according to the inv...
