The invention provides catalysts suitable for hydrotreatment of mineral oil which contain an oxide and/or sulphide derived from a metal of Group VI (B) and one from Group VIII metal and a transition alumina and which show an oxygen chemisorption above 185 micromoles per gram, preferably between 200 and 300. Preferably tha catalysts are free from anions of strong mineral acids. These catalysts can ...

A relaxometric sensor for the detection of muscular contraction induced by electrical stimulation in the area of the hand using strain gauges as electrical transducers, is constructed in sandwich form from a resiliently deformable support element 1, a covering element 3 which is also resiliently deformable, and a resiliently deformable insert 2, positioned between the support element 1 and the cov...

Installation comprising a reservoir crucible 11, 12 for molten cast-iron F with step-by-step extraction of a pipe T produced from the crucible comprising a cooled die. To obtain a cast-iron pipe of uniform thickness over its entire circular periphery, despite the absence of a core, the molten cast-iron F is set in slow rotation in the crucible by the tangential supply of molten cast-iron with a lo...

A primary layer (1) is free of binder, and has a density of 20 - 600 kg cubic metre and a surface weight of 70 -1800 sq. metre. It has a water absorption property which extends to 4 -25 grams per gram of surface material. The loose fibre layer is encompassed by covering and support layers (2, 3) comprising fibres temporarily bound to each other, with a density of 50 -900 km cubic metres. Each cove...

The roller track (7) is movably located on a frame (1) for displacement relative to its parallel to the direction of transport. This permits the alteration of the track position relative to the goods (B-E) which are located on it between the upper and lower positions.

A holder (22) retains a valve slide (13) in a first open position. When there is an excessive back flow of pressure medium from one outlet port (A) to the other (B), the slide adopts a second position in which the valve is closed. In this second position, the valve slide-with a sealing surface (21) surrounding the flow channel (17)-locates against a seat plate (16) which blocks the channel.

A process for the selective preparation of essentially non-cyclic polyalkylenepolyamine compounds is described. In this process, an alkyleneamine compound is reacted with a hydroxy compound and optionally ammonia or an alkyleneamine in the presence of a catalytically active amount of an acidic crystalline aluminium silicate at a temperature of about 175 DEG C to 400 DEG C under a pressure which is...
