Abstract: ABSTRACT OF THE DISCLOSURE           A modular telecommunication system comprises   switching blocksinterconnected by bus-oriented interconnecting lines.  Each switching block  includes line terminators each adapted to be connected to a respective data terminal and control means for controlling local data exchange between line terminators directly connected thereto and remote data exchange Prom local line terminators to a data terminal associated with a different switching block. The interconnecting lines include a plurality of individually controlled interlink buses, which are coupled to each switching block by a separate interlink-bus interface unit and a short distance transmission line.  Data transfer across an interlink bus is performed under control of an interlink-bus controller associated with each bus, by scanning the interlink-bus interface units.  Data characters are transmitted in time-multiplex mode together with address information of the receiving switching block for selecting the receiving interlink-bus interface unit. the receiving unit stores the data in a buffer memory intermediately before transmitting the same to the associated switching block.

Abstract: ELECTRIC INCHING IMPULSE CONTROL   ABSTRACT OF THE DISCLOSURE There is provided an electrical inching control for inching a drive system comprising a grinding mill driven by one or more three phase synchronous motors.  The electric inching control includes an inching power bus and contactors or the solid state equivalent thereof.  The inching bus supplies energy to the stator windings of the synchronous motors.  The contactors or switches connect the positive and negative sides of a direct current power supply to the different phases of the stator windings in a sequency which provides a stepped rotating magnetic field, and the-rotor field windings are excited with direct current. The interacting stator and rotor fields causes a rotation of the rotor a predetermined amount with each step causing the mill also to rotate a respective predetermined amount. The electric inching control of the present invention further includes a vibration sensor which detects vibration in the gearing driving the mill and the signal from the vibration sensor is applied to a feedback voltage magnitude control which adjusts the magnitude of voltage applied to the stator windings of the synchronous motors reducing the voltage as the signal representing vibration increases to reduce the adverse mechanical forces incurred by the mill.

Abstract: . A switching system comprising an exchange(1) with n signal inputs(5) and m subscriber outputs(14) and switching means(6, 7) in the exchange for each subscriber for supplying a signal from one of the signal inputs through a signal separating circuit to the related subscriber output. Between each subscriber output and each subscriber terminal(11) there is a cable connection(2). Each subscriber has signal selecting means(13), which as the subscriber signal receiver(12) are connected to said subscriber terminal and by means of which selecting signals can be transmitted through the cable connection and through said signal separating circuit to a control unit in the exchange for controlling the switching means assigned to the related subscriber. For each subscriber terminal a frequency converter (9) is installed in the exchange between said switching means and said signal separating circuit, which frequency converter converts the signals received through said switching means to a frequency band or channel which can be received by the subscriber signal receiver.

Abstract: ABSTRACT           A  combustor  capable  of  reducing  the  noxious emissions  such  as  fuel  bound  and  thermal  nitrogen oxide products,  during  combustion  of  high  nitrogen bearing  and high  aromatic  content  fuels is disclosed. The  combustor  includes  a  plurality  of  substantially concentric   pipes   defining   annular   passages   with annular   divergent   nozzles.    The   divergent   nozzles may  be  formed  by  rings  having a  venturi   shaped axial  section  to  facilitate  fast  mixing  of  axially supplied   air   between   adjacent   annular   passages. The longitudinal spacing between at  least two  adjacent nozzles  defines  first  and  second  divergent  cavities. A  fuel  rich  toroidal  vortex  is  formed  in  proximity to  a central  fuel  jet in the first cavity and advan-tageously  converts  fuel  bound  nitrogen  to  N2.   A fuel   lean   toroidal  vortex  formed  in  the   second cavity  mixes  hot  combustion  products  with  additional gaseous  reactant  to  complete  the  combustion  while avoiding  locally  high  temperatures,  and thus  thermal NOx   formation.    A   ring   of   jet  nozzles  radially injects  relatively  small  amounts  of  high  pressure gaseous reactant or steam to form a throat to separate and   stabilize   the   vortices.    Alternatively,   the pipe  extending  between  the  two  cavities  can  include a   convergent   and   divergent   portion   forming   the throat   between   the   cavities   for   separating   and reinforcing  the  toroidal  vortices.   Guide  vanes  may be  positioned  in  the  annular  passages  to  swirl  the gaseous  reactant  entering  the  cavities  to  assist  in the formation of the toroidal vortices.

Abstract: SEAT POSITIONER                   ABSTRACT OF THE DISCLOSURE A seat-positioning mechanism is disclosed and is of the type which includes an elongated housing having a rod slidably received therein for movement in either direction with respect to the housing.  The housing contains friction lock elements which have a locked position canted about a fulcrum to be in frictional engagement with the rod.  This engagement frictionally restrains the rod against the movement in at least one direction with respect to the housing.  The friction lock elements have an unlocked position wherein the friction lock elements are disposed substantially perpendicular to said rod and out of frictional engagement therewith to permit free movement of the rod with respect to said housing to any selected position.  The housing also includes a spring operatively connected to the friction lock element to urge the friction lock element towards the locked position.  A cam, which is capable of tilting the friction lock element into the unlocked position is also included within the housing.  A positioning element is located between the friction lock element and the spring.  The positioning element is capable of preventing movement of the friction lock elements along the rod in the canted position upon actuation of the cam.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a field probe for use with an electromagnetic type of intrusion detector, in which an electromagnetic field emanating from a cable is coupled to a receiving cable and in which a disturbance to the field is detected, thus providing an indication that an intruding body has entered the field.  The field probe provides a means for simulating the entrance of an intruding body into the field, and thereby affording means for testing the intrusion detector system and facilitating calibration.  The probe consists of an antenna located between the cables with a transmission line connected to the antenna, and a switchable termination to the transmission line for varying the reflection coefficient of the transmission line termination.  The phase of the reflected field is thereby changed which simulates the entrance of an intruding body into the detector region.
