Prodn. of gaseous mixts. of H2 + CO by partial oxidn. of a feed comprising a heavy liq. hydrocarbon fuel and/or petroleum coke, each contg. at least 0.5 wt.% S, and giving ash contg. at least 5% V, at least 2% Ni, and Si involves (1) mixing the feed with additive A contg. Fe when the Si content of the ash is less than 350 ppm, or B contg. Fe and Ca when the Si content of the ash is at least 400 pp...

A lycosphingolipid derivative is disclosed which is useful in binding glycosphingolipids to an immunoadsorbent matrix. The process for preparing the immunoadsorbent leaves the oligosaccharide and lipid components of the glycosphingolipid unaltered after conjugation with the solid support matrix, while at the same time permitting a covalent and stable bond between the glycolipid and solid matrix.

Data processing apparatus comprises a series of pipeline units each of which consists of a number of pipeline stages. The units are interconnected by a number of parameter files, which provide a number of slots. Whenever an instruction is initiated in the pipeline, it is allocated a slot, and retains that slot until its execution is successfully completed. Two independent streams of instructions a...

The yarn roll (8) is provided with a stripe-code which gives the price and data specific to the item.So that the stripe code does not impinge upon the matching of the thread's colour with that of a sample, and also does not obscure the yarn roll's field of colour vision in a sales display, the yarn roll (8) is furnished with an, at the very least, almost u shaped stirrup (1) arranged within the ro...

A process for the application of twin layer bottoms on the pots, wherein the filling material of the hollow space is located on the bottom of the pot and kept at a certain distance from its profile, being a covering layer located above it, by operating them according to the Italian Pat. No. 965,732. The process is characterized in that the height of the filling material is at least 20% higher than...

In the production of ethylene oxide by the reaction of ethylene and oxygen with subsequent recovery of the ethylene oxide so formed and recycle of a gas mixture containing argon and unreacted ethylene, the argon concentration in the cycle gas is reduced without significant loss of ethylene by use of a semi-permeable membrane unit.

A drain arrangement in which the cover grating 1 of the drain can be easily lifted for cleaning. When a push button or the like located at the centre point of the cover grating 1 is pressed down, a projection 7 emerges from the cover grating 7 as a result of the levering mechanism 3, 4, 5 situated under the cover grating. By pulling the said projection up, it is possible to release the cover grati...

An apparatus for producing cooling gas for a producer gas produced in a melt-down gasifier and surplus gas usable in an appropriate manner by cooling and cleaning at least part of the producer gas and the top gas of an iron ore reduction unit are proposed. The cooling gas is exclusively obtained by preparing producer gas. There is a cooling and a cleaning unit for the surplus gas and the cooling g...

A process for making a randomly patterned carpet from a rubber preform with areas of contrasting colour, in which the preform is first converted into the form of a blank having raised portions which protrude relief-like from the upper side, is strengthened by vulcanisation and is subjected to cutting in the region of the raised portions only. To form the areas of contrasting colour, the rubber is ...
