Abstract: ABSTRACT For monitoring stranding machines for breakage or run-out of single strands, a device is employed which checks the rope or cable after stranding for uniformity of the rope or cable surface.          For this purpose, an electrical image of the rope or cable surface is read into a memory and the measured values compared with this stored pattern during the further stranding process.  In the event of deviations resulting from this comparison, disconnecting or other actuating elements are actuated in order to avoid the production of further faulty lengths of rope or cable.          For reflection measurements, electromagnetic, optical or acoustic waves can be employed.          Instead of scanning of the rope or cable surface based on reflection, corpuscular radiation which partially penetrates the rope or cable can be employed.

Abstract: ABSTRACT.     A process to produce by covalent binding con-jugates of a substance containing a 2-amino-2-deoxy-glycopyranosyl residue the NH2-function of which in its most stable conformation is equatorially oriented, and a substrate containing a primary amino group. This is done by subjecting the substance to degradation by diazo-tation to form a substance fragment having a free terminal aldehydo group, said fragment through its aldehydo group being reacted with the amino group of the substrate to form a Schiffs base which is then by reduction converted to a secondary amine.      The substance is preferably selected from oligo and polysaccharides containing glucosamine or galactose amine units.    The substrate is suitably selected from surface-aminated plastic objects, aminated gels and proteins.     The conjugate described consists of an 1-deoxy--2,5-anhydrohexitol unit   which constitutes terminal unit   in an oligo or polysaccharide and which in 1-position is covalently bound to an amino group associated with a substrate.

Abstract: Abstract Disclosed is a channel unit (109) for connecting a carrier channel multiplex or tie line directly to a terminating unit line such as that terminating a private branch exchange (102) or a telephone station set (117) thereby eleminating the normal local end office interconnection.  In particular, the channel unit interfaces the different signaling protocols of the interconnected lines and generates call progress control signals such as dial tone and audible ringing which are normally generated by the local end office.  The channel unit comprises a converter (205) for each line for converting the electrical interface signals representative of the busy and idle conditions of the line to logic levels also representative of the busy and idle conditions of the line.  A predetermined series of these logic levels form a control signal that indicates the state of a call on the line.  Since the control signal indicative of the state of the call on one line is typically not useable by the other line, a microprocessor (204) included in the unit generates a second control signal to advance the state of the call on the other line to an equivalent call state.  An additional converter (205) then converts the logic levels of this second control signal to the electrical interface signals of the other line to advance the state of the call to the equivalent call state.  The unit further comprises a receiver (201) and transmitter (202) for exchanging dial pulse and dual tone multifrequency address signals between the lines.  Also, included are circuits (203, 226) for applying call progress control signals such as dial-tone, audible ringing, and power ringing to the lines (FIG. 2).

Abstract: ABSTRACT OF THE DISCLOSURE       The process of liquid-liquid extraction of gallium from sodium aluminate  liquor used in the Bayer alumina process, uses an organic extractant comprising a diluent and a substituted hydroxyquinoline such that gallium and some aluminum are extracted into the organic phase.         In five successive steps, the organic extractant solution loaded with gallium and aluminum is first contacted with an aqueous mineral acid solution, during which the acid solution strips the loaded solution of gallium and aluminum.          Next, the phases are separated and a chloride salt or hydro-chloric acid is dissolved in the acidic solution of gallium and aluminum which is then contacted with an organic solvent, e.g. n-butyl acetate.  Aluminum remains in the aqueous acid solution whereas the organic solvent becomes loaded with gallium.         After the phases have been separated, the organic solvent is separated from gallium chloride, which forms the feed for producing pure gallium.
