IPC: H01F27/34

Abstract: ABSTRACT OF THE DISCLOSURE   Iron-core discs which together with intermediate layers disposed between the discs and yokes covering the discs at the end forming the iron core of multiphase chokes are often held together by metal tension elements symmetrically penetrating the iron-core discs.  To reduce the alternating magnetic field strength occurring in the metal tension elements, these elements are surrounded according to the invention by a jacket made of a material having a very good electrical conductivity.  The eddy currents pro-duced in the jacket thereby reduce the magnetic field strength in the interior of the tension element to a partial amount which is just sufficient to main-tain the eddy currents in the jacket.  Tension elements which are encased in accordance with the invention make possible particularly economical arrangements in chokes with large electrical power outputs.

Abstract: ABSTRACT A dynamic noise filter especially adapted for use in audio reproduction systems within a television display device is provided to eliminate perceived noise. An audio signal having a relatively wide frequency range is passed through a variable bandwidth lowpass filter, the upper frequency cutoff point being variable in response to a control signal.  A control path includes a filter and detector circuit for generating the control signal in response to the amplitude of the audio signal within an upper frequency portion of the audio signal frequency range.  The control signal controls the bandwidth of the lowpass filter inversely with respect to the level of the audio signal within the upper frequency portion of the frequency range.  A further filter is included in the control path for providing substantial attenuation at the fundamental frequency and lower order harmonic frequencies of the television horizontal line scanning signal in order to prevent the control path from erroneously responding to this signal.

Title: Industrial control system with interconnected remotely located computer control units

IPC: H04L1/22

Abstract: INDUSTRIAL CONTROL SYSTEM WITH INTERCONNECTED REMOTELY LOCATED COMPUTER CONTROL UNITS A control system for controlling an industrial process includes a plurality of remotely located process control units (remotes) each coupled to an associated input/output device(s) and adapted to communicate with one another through a dual channel communications link. Each remote has a unique succession number within a predetermined succession order with supervisory communication-control of the communication link sequentially transferred to each remote according to its succession number to provide a revolving or master for the moment control of the system. Digital information in the form of data and control information blocks is transmitted between the remotes with the blocks transmitted twice on each channel of the communications link. The destination remote tests the block validity on one of the two dual channels and, if validated, responds with an acknowledgement signal (ACK) and, if invalid, tests the blocks on the other, alternate channel and then responds with an acknowledgement or non-acknowledgement signal (NAK) depending upon whether the data blocks tests on the alternate channel are found valid or invalid. A nonacknowledgement from the destination remote re-triggers the transmission of the blocks from the source remote. The system provides high overall operating efficiency since the remotes will maintain a system-like integrity on each side of a severed communication link and the redundant block transmission with alternate line checking provides very high information transfer reliability.

Abstract: ABSTRACT:          A fuse for projectiles.     The invention relates to a fuse for rotating projectiles having directive explosive force, whereby is meant that the projectile has effect in one direction only, which direction does not coincide with the length axis of the projectile, and substantially no effect in other di-rections. The fuse according to the invention comprises two sensors. A first sensor with a narrow sensitivity lobe in a direction not coinciding with the length direction of the projectile, suitably the same direction as the direc-tion for maximal explosive force, produces a pulse signal each time its sensitivity lobe is directed towards a target, and a second sensor monitors the distance to the target. The pulse signal obtained from the first sensor is used to initiate burst at a moment when the direction for maximal explosive force coincides with the direction to the target, provided that the second sensor indicates that the projectile has entered a given distance zone from the target.

Abstract: A B S T R A C T                 LEAK DETECTION FOR BS AND W APPARATUS      A process is provided for measuring the water and sediment content of a wet stream which is predominantly non-aqueous. The process requires removing a sample of the wet stream, extracting a dry stream sample from the wet stream sample, and comparing the dielectric constants of the wet and dry streams. Leakage of any of the wet stream sample into the dry stream sample will adversely affect the comparison of dielectric constants. Accordingly, periodically the apparatus used for the process is checked for leakage by blocking conduits carrying the dry stream sample to a holding chamber.

Abstract: ABSTRACT:           Field effect transistors having a short channel length are desirable for carrying out logic operations at a high speed.  However, they are then not capable of withstanding the comparatively high programming and eras-in voltage at which an (E)EPROM has to be operated.          During the programming cycle the field effect transistors are kept in the current-non-conducting state, whilst recording the logic information obtained by the logic operations, the "fast" transistors are nevertheless capable of withstanding the comparatively high voltage.

Abstract: Abstract A process for cleaning out deposits collected in the  restricted  areas  of the  secondary  side  of  a  steam generator  of  a  nuclear  power  plant  system,  where  the concentration of an aqueous organic cleaning agent solution is increased  in  the  restricted  areas,  relative  to  the remainder of the solution.  The solution is heated, at an initial pressure which prevents boiling of the solution, and the pressure is reduced to effect  localized flashing and boiling of the solution in the restricted areas. After a period of time, the pressure is increased and the cleaning agent solution,  containing solubilized deposits,  is with-drawn from the secondary side of the steam generator. The heating temperature and pressure will vary depending upon the type of deposit to be removed, either ferrous-type or copper-type deposits.
