The invention relates to a jack bracket (12) for a motor vehicle, which is fixed to a sill of the motor vehicle with flanges and an opening (16) for a receiving element in which the jack is placed. The invention also relates to a method for the production of said bracket (12). In order to simplify the production and configuration of the bracket (12) without comprising its stability, the bracket (12) is comprised of a tubular hollow profile (6) and a lid (13), which is fixed on the end (10) opposite the sill of the hollow profile (6) covering said end (10) and which has the opening (16) for the receiving element.
摘要:
Metal is separated from a gaseous mixture formed during reduction of a compound and which contains metal vapour by contacting the compound with an absorbent capable of absorbing the metal vapour and under thermodynamic conditions such that the metal vapour is directly absorbed by the absorbent.

A rear structure of a unitized motor vehicle body with two side wall sections includes a transverse wall located below a rear window cutout. The transverse wall connects the sidewall sections with one another, and has two cross members spaced apart from one another, between which a flat part extends. The first cross member, adjacent to the rear window cutout, is fitted with zero play between the side wall sections and a bearing is provided for the second cross member on each side. The bearing ensures an adjustability of the second cross member between the side wall sections at least in the transverse direction of the vehicle. The flat part is a trim member connected exclusively with the two cross members.
摘要:
A process for the finish dressing of leathers dressed by a mineral or a combined method, by treatment with an aqueous solution of water soluble polymer dressing substances that are polymers of unsaturated monomers that contain sulfonic groups. These polymers contain, if necessary, additional basic units that do not affect the water solubility, these being derived from the comonomers that can be copolymerized with the monomers that contain the sulfonic groups and which do not contain phosphorus.
摘要:
Halides of alkali and alkaline earth metals ("metals") are reduced with gallium, indium or thallium ("reducing metals") at temperatures below their boiling points at vapor pressures at which the gaseous monohalides of the reducing metals are formed. The quantity of the reducing metals is chosen such that it is sufficient both for the reduction of the metal halides and for the simultaneous solution of the metals formed, e.g.:MgCl.sub.2 (s)+2Ga(l)=Mg(l)+2GaCl(g); 900.degree. K., 0.02 torr.The metal is distilled off from the melt formed and is condensed the metal-free reducing metal is recycled for the reduction of the metal halide.The reducing metal is recovered from the monohalide for re-utilization in the halide reduction; this is effected by reduction of its oxide which is formed either by oxidation of the monohalide, or by oxidation of the trihalide resulting in the disproportionation of the monohalide in addition to elemental reducing metal.The continuous process design, the loss-free recycling of the reducing metal, the utilization of the heat of exothermal processes, and a minimum consumption of electric power permit a high profitability of producing alkali and alkaline earth metals according to the invention.
摘要:
The process is based on the series of halide-forming affinities. The oxides are passed through a series of zones equal in number to the plurality of halides or mixtures which are to be produced. A halide of an element of lower halide-forming affinity is fed counter-current to the oxides. The halide supply is in stoichiometric equivalent to the total content of halide to be extracted. The oxide of the said fed element is also extracted.

As a leather fatting agent a solution, emulsion or dispersion of a pulverulent, free-flowing form product derived from a substance having a liquid or pasty consistency, especially fatty, oil and waxy substances, especially those prepared by drying aqueous solutions or dispersions containing these substances together with carrier compositions having the dry weight analysis of from 0.1 to 35% inorganic or organic salts, 0.1 to 90% albumin or albumin derivatives and 0.1 to 70% of mono-, oligo- or poly-saccharides or derivatives thereof; a method of fatting a leather which comprises contacting said leather with a solution, dispersion or emulsion of a free-flowing pulverulent product derived from a substance having a liquid or pasty consistency, especially fatty, oily and waxy substances and especially those substances prepared by drying an aqueous solution or dispersion containing the same, together with a carrier composition having the dry weight analysis set forth above in respect of inorganic or organic salts, albumin or albumin derivatives and mono-, oligo- or poly-saccharides or derivatives thereof.

摘要:
The invention relates to a process for improving the lightfastness of conventionally dyed leathers by treating the leathers before, during or after fatting with alkane and/or chloroalkane sulfonamides in amounts of about 0.1 to 8 weight percent, based on the shaved weight of the leather. Used as alkane sulfonamides and chloroalkane sulfonamides are preferably products with a chain length of about 10 to 35 carbon atoms and a chlorine content of about 10 to 40%. The alkane and/or chloroalkane sulfonamides are advantageously used in aqueous solution or in stable emulsion. A substantial improvement in lightfastness is obtained regardless of the type of the dye, tanning agent, fatting agent or other leather treating agent used.
