Abstract: An installation for treating metal wire, such as for coating a copper conductor, comprises at its upstream end a stationary wire-supply source having a reel support disposed within a loop-guard made of a gray iron or ductile cast-iron part in the form of a hollow body of revolution having an ogival profile. This part bears at its downstream end a conical tip defining the exit aperture for the wire. The inner surface of the loop-guard is machined by turning so as to be absolutely smooth and may also be subjected to a hardening treatment.

Abstract: A method of, and apparatus for, loading transporting trolleys with full cans and supplying full cans to spinning machines fed with fiber sliver, wherein the empty cans are placed upon transporting trolleys interconnected to form a transporting trolley train and transported from a spinning machine fed with fiber sliver to a can loading device. The cans are transported from their transporting trolley first to a can take-up station, then are engaged by a revolving can transporting device which transports each of the cans to a spinning preparatory machine delivering a fiber sliver and where each of the cans are filled with the fiber sliver. After filling the cans are transported via a can output station back onto a transporting trolley of the same train and such transporting trolley train is then brought back to the spinning machine fed with fiber sliver.

Abstract: The wheels of the cart are arranged so that a front wheel and a rear wheel can be interconnected with each other and driven off a steering gear. Upon pivoting of the steering gear during turning of the cart, these front and rear wheels pivot in opposite directions so that the rear wheel follows in the wake of the front wheel. When disconnected from the steering gear, the front and rear wheels, as the remaining wheels, are freely rotatable.

Abstract: The invention provides a new process for the manufacture of aromatic compounds which at least once contain a benzene ring of an aromatic carbocyclic ring system bonded by an ethylene double bond in conjugation with a further aromatic ring system, i.e. contain the stilbene skeleton or stilbene analogon as central structural element, as well as certain classes of new compounds of this type. The process is characterized by the reaction of a Schiff base of an aromatic aldehyde with an aromatic carbocyclic six-membered ring compound which contains one to four methyl groups bonded to ring carbon atoms of a benzene ring, which furthermore contains aromatic rings which are exclusively six-membered carbocyclic rings, and wherein those benzene rings whose methyl groups are to be caused to react are free of other substituents which contain atoms which are replaceable by alkali metal. The reaction is carried out in the presence of (a) a strongly basic alkali compound and (b) an N-dialkyl-acylamide as solvent.
