Abstract: Abstract:     An internal mandrel is disclosed which is used for supporting the inner wall of a pipe during bending.  The internal mandrel includes a urethane plug which is compressed between the piston of a hydraulic cylinder and an end plate.  This expands the urethane radially outward into contact with the inner wall of the pipe to support the pipe during bending.  Resilient steel strips can be mounted on the exterior surface of the urethane plug at the inside bend of the pipe to increase the effective wall thickness of the pipe at the inner bend to reduce the likelihood of deformation during bending.  In a second embodiment, internal mandrel includes an annular urethane plug positioned between a resilient cylinder and the inner wall of the pipe.

Abstract: A b s t r a c t The invention relates to a process for maintaining weld quality during wielding operation, marking the fault spots on the workpiece and certi-fying of quality, in course of which momentary va-lues of arc current and arc voltage characterizing manual or mechanized welding process are continuous-ly measured and from the values thus obtained rela-tive short-circuit time of the arc, drop frequency and arc outputs (powers) are continuously calculated.         The essence of the invention lies in that measured and calculated values are compared with em-pirically determined optimal values, thus defining absolute values and signals representing the direc-tions of deviations, as well as duration of devia-tions, thereafter - related to a predetermined span of time - averages of absolute values and signals representing the directions are defined, furtheron the quotient of the duration of deviations and pre--determined duration is formed. Averages and quotients are recorded and simultaneously averages of the ab-solute values are related to a first and second li-mit value and in case, if they fall between the first and second limit value, a warning signal is given for the welder, whereas, if averages are surpassing the second limit value a further signal is given and si-multaneously fault spot is marked on the workpiece as long as averages are reduced below the second li-mit value.

Abstract: A WIDEBAND DIGITAL SWITCHING NETWORK            Abstract Disclosed is a wide bandwidth self-routing switch. One-to-one, one-to-many, and many-to-many modes of communications are achieved with time multiplexed signal packets of multi-service users with a system having a bank of demultiplexers which demultiplex incoming signals and supply them to a broadcast network.  The broadcast network includes a concentrator a "sort on source" sorting network and a copy network.  The concentrator permits a reduction in subsequent processing by segregating the incoming lines which carry active signals.  The "sort on source" sorting network places all blank copy packets (which are destined to users that wish to tune to a broadcaster) adjacent to the broadcaster's signal packets.  The copy network copies the information in the broadcaster's signal packets into the packets destined to the users.  The blank copy packets are continually generated by the users wishing to receive broadcasts or, alternatively, by a blank packet generator.         Signal packets exiting the broadcast network enter a wide bandwidth switch which includes a "sort on destination" sorting network and an expander.  The "sort on destination" sorting network arranges the packets in the order of their destination addresses and the expander routes the sorted packets to the desired destinations.  The output signals of the expander are time multiplexed and the multiplexed packets are sent to the users.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for welding studs utilizing a two-wire control is provided.  The apparatus includes a stud welding tool capable of welding studs by a drawn-arc technique.  A stud welding control circuit and a source of welding power are remotely located from the tool with the difference exceeding one hundred feet in some applications.  Heretofore, two wires were required to connect the tool and the control circuit to initiate the welding cycle and two additional wires were required to control movement of the stud during the welding cycle independently of the position of a start switch on the tool after the switch is closed.  The present apparatus requires only two wires to both initiate and control the weld cycle.  This reduces costs and maintenance and increases reliability and maneuverability of the tool.

Abstract: ABSTRACT        The carbonate ion selective membrane of the invention com-prises (a) a polymeric inert support material;  (b) a plasticizer effective to solubilize the support material;  (c)  a quaternary ammonium ion;  (d) an ionophore which is preferentially reactive with carbonate ions; and (e) a hydrophobic molecule effective to exclude ions other than carbonate ions.  The addition of a hydro-phobic molecule to the membrane formulation serves two purposes. First, it assists in the "binding" of the organic constituents to the matrix.   Second, it repels charged species, i.e., anions and cations, from the solution phase, thereby improving selectivity to the  carbonate  species which  enters the membrane via selective complexation with the ionophore.  The quaternary ammonium ion is preferably a C7 to C9 quaternary ammonium ion. In this case, the plasticizer is selected to be one effective to maximize the binding of carbonate ions with the C7 to C9 quaternary ammonium ions.  The invention further provides a carbonate ion selective electrode comprising an internal reference element in electrochemical contact with the membrane described above.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous co-extruded food product is formed having dissimilar inner and outer portions wherein the inner portion is enveloped by the outer portion and the outer portion is a dough containing particulate material such as chocolate chips.  The product is formed by an inner extrusion port being recessed a distance d from an outer extrusion port with the distance d being sufficient for permitting particulate material in the outer dough portion to pass through an exit passage between the inner and outer extrusion ports without clogging or agglomeration.  Turbulence is induced in the outer dough portion which envelops the inner portion thereby causing the particulate material to tumble whereby at least a portion of the particulate material partially penetrates the exterior surface of the outer dough portion enveloping the inner portion.  Dough is removed from the surface of the part of the particulate material penetrating the exterior surface of the outer dough portion.          In a preferred embodiment, the outer extrusion port includes a land surface generally parallel to the axis of the outer extrusion port and a bevel surface at the interior surface of the outer extrusion port.  The land surface intersects the beveled surface at a generally sharp line of interjection.    The generally sharp line of intersection and the bevel surface cause the tumbling of the particulate material.  The land surface removes dough from the surface of the particulate material which penetrates the exterior surface of the outer dough portion.
