Abstract: A method of tanning rawhide by pickling the rawhide after the preparatory operation has been finished, and then treating the pickled rawhide with chromium salt to thereby prepare leather. According to this invention, the pickling process is performed in the presence of urotropin (hexamethylene tetramine), whereby the pH value in a tanning bath of chromium salt may be easily adjusted, the coupling of rawhide with basic complex salt of chromium may be increased, and the amount of the residual chromium in the waste liquid may be minimized. Further, in order to improve the operation efficiency in the finishing step, to further enhance the quality of the leather, and to render the chromium content in the waste liquid almost zero, the tanned leather is treated with ammonia or weakly acidic ammonium salt in the used chromium bath.

Abstract: To enable additional information to be transmitted at an unchanged clock rate in a transmission system, the information input at the transmitting end, which is present in the form of digital pulse packets of equal length limited by separators, is converted into a code with packets of unequal length in a code convertor (2). These are separated by clearly distinguishable separators. This makes it possible to transmit fewer pulses in the statistical mean for a given message length. Into the gaps produced in this manner, additional pulse packets from an auxiliary store (4) are inserted by means of a mixing stage (5). After the transmission, these are separated in a separating stage (9). The remaining pulse packets are returned to their original form in a code reconverter (11). Clock generators (7, 13) ensure that the basic clock is maintained at the transmitting end (A) and at the receiving end (B). The information additionally transmitted is stored in an auxiliary store (8) at the receiving end for further processing. <IMAGE>

Abstract: A novel composition of matter is disclosed, consisting of a hydrocarbon solution of an alkylsodium compound of the formula
     in which R 1  and R 2  are independently straight-chain C 2 -C 6  alkyl and R 3  is hydrogen or straight-chain C 1 -C 3  alkyl. The solution is prepared by reacting metallic sodium with a halide of the above alkyl group in the presence of a saturated aliphatic or alicyclic solvent, followed by the removal of solids from the resulting solution. 
    
     Background of the Invention 
     This invention relates to hydrocarbon-soluble sodium alkyls. In particular, this invention relates to solutions of alkylsodium compounds in aliphatic or alicyclic hydrocarbon solvents. 
     Alkylsodium compounds are known for a variety of uses in chemical technology. As cocatalysts with halides of metals of Groups IV through VI of the periodic table (see Handbook of Chemistry and Physics, 52d ed., The Chemical Rubber Co., Cleveland, Ohio, 1977), alkylsodium compounds are useful in the polymerization of olefins such as ethylene, propylene, butadiene, and isoprene. They have also been used both alone and as cocatalysts in the polymerization of acrylates, acrylonitriles, lactones, and other monomers. Alkylsodium compounds are also useful as alkylating agents and metal- ating agents since they are more reactive than Grignard reagents. 
     Sodium alkyls are highly reactive, high-melting solids that are generally insoluble in hydrocarbon solvents. It is to this reactivity that sodium alkyls owe their broad utility. Unfortunately, water, carbon dioxide, and oxygen, common components of atmospheric air, are included among the many materials that react with sodium alkyls. Thus, sodium alkyls must be handled in an inert atmosphere, preferably under a gaseous blanket of nitrogen or argon. Under such conditions, the compounds can be handled as dry powders. Preferably, however, they are handled in suspension or in solution in an inert hydrocarbon liquid, in order to improve ease of handling and minimize the chances of contamination. Hydrocarbons are preferred over other liquid solvents, particularly ethers since, although useful as solvents for less reactive organometallic compounds, ethers are cleaved by sodium alkyls to form sodium alkoxides and other products. 
     Since sodium alkyls are most conveniently prepared by the reaction between sodium metal and an appropriate alkyl halide, the insolubility of the product makes recovery from the other solids in the product mixture difficult. In addition, insoluble sodium alkyls are inconvenient to transfer and handle since they are normally stored as suspensions in hydrocarbon solvents to enhance their stability. Furthermore, when used as catalysts or reagents, their solid form makes it difficult to control reaction rates. Clearly, it would be desirable to obtain sodium alkyls which are soluble in hydrocarbons.

Abstract: n a trailer having steerable wheels, there is provided a restraining mass which, in response to the lateral acceleration of a turn, applies a steering force to the wheels such that the tyres generate a side force toward the centre of the turn which is equal and opposite to that of the trailer resulting from the acceleration. As a consequence, no net force is exerted on the tow vehicle by the trailer, preserving its handlung characteristics. The steering force is derived from a mass (48) on the trailer acting on a connecting tie-rod (24) through an arm (40) pivoted on the axle (10), or through use of the mass of the trailer itself.

Abstract: The ammonia contained in ammonia- and hydrogen sulfide-containing gas mixtures is selectively removed through a gas washing with an aqueous ammonium sulfite-bisulfite solution, and recovered from the wash solution as a concentrated aqueous solution. For this purpose the coke oven crude gas is washed with an ammonium sulfite-bisulfite solution led in circulation, the surface tension of which amounts to below 80x10-5 N/cm, then the ammonia gas is driven away from the wash solution enriched with ammonia, e.g. by means of steam, and the released ammonia is recovered e.g. as aqueous ammonium solution through condensation of the vapor. The gas mixture is preferably purified or unpurified coke oven crude gas. In order to reduce the surface tension of the wash solution, alkyl sulfate, alkylamine, pyridine base, phenol or homologs thereof are added as surface active substance. The wash circulation is performed at between 15 DEG  and 32 DEG  C.
