Title: Method and apparatus for canceling quadrature distortion as for video signals have in-phase and quadrature phase components
Inventor: GIBSON JAMES J
IPC: H04N11/24
Filed: 1991-07-30
Abstract: High definition or enhanced television signals include supplementary information which is double-sideband modulated in quadrature with the picture carrier, and passed through an inverse Nyquist filter (222) before being combined (224) with a con-ventional vestigial sideband (221) modulated main video signal. A receiver which recovers both the main video signal and the supplementary information processes the received video signal through an IF filter (228) having a vestigial sideband frequency response characteristic. Two synchronous detectors (230, 232) recover in-phase and quadrature phase signal components from the filtered television signals, these recovered signals each include, quadrature crosstalk distortion components from the other signal. The crosstalk from the supplementary signal into the main signal is cancelled by filtering (246) the recovered quadrature signal and adding (244) the result to the recovered in-phase signal. This filtering also equalizes the in-phase signal by converting the quadrature distortion components in the recovered quadrature signal into reinforcing signal components in the in-phase signal. This signal recovery system is advantageously used with a ghost concellation system.

Filed: 1993-02-04
Abstract: ABSTRACT OF THE DISCLOSURE         The reactor switch is provided for switching on and off a reactor  (2) which is arranged in a multi-phase electrical high-voltage network.  It has switch poles (3) which are arranged phase-by-phase between the reactor (2) and a part of the network containing, for example,  a high-voltage line  (1).  These switch poles (3) in each case contain at least two series-connected switching chambers  (11,  12;  13,  14)  in parallel with which at least two series-connected varistors (15, 16; 18, 19) are connected.        This reactor switch is intended to be capable of disconnecting short-circuits occurring between the reactor switch and the reactor (2) without problems.          This is achieved in that the at least two varistors  (15,  16,  17, 18,  19)  and the at least two switching  chambers  (11,  12;  13,  14)  are  connected together in the form of a network on which the high-voltage network acts in terms of current and voltage and in which, in the avent of-restriking of some (11, 12) of the at least two switching chambers, the energy which is supplied to those varistors (17, 18, 19) which are connected in parallel with the switching chambers (13,  14) which are free of restrikes is less than in the case of a reactor switch having a network which is acted on in a corresponding manner, but in which each of the at least two switching chambers is bridged by at least one of the at least two varistors.

IPC: H04B7/26
Filed: 1993-02-23
Abstract: A method and system are disclosed for enhanced data transmission within a cellular telephone system having multiple  assigned  voice  channels  separated  by  adjacent buffer  voice  channels.   A  data  processing  terminal  is utilized to divide the data stream into multiple relatively short data packets which are then sequentially transmitted within  alternate  adjacent  buffer  voice  channels.   By switching  from  one  adjacent  buffer  voice  channel  to  a subsequent adjacent buffer voice channel, in a predetermined and repetitive order,  as each data packet is transmitted, the amount of interference experienced in any one assigned voice  channel   is  minimized.    Synchronization  between adjacent data packets may be achieved by either utilizing adjacent  buffer  voice  channels  in  a  predetermined  and repetitive order or by concatenating an indication of the next buffer voice channel utilized with each data packet.  A synchronization packet may also be included with each data packet  to  permit  synchronization  between  adjacent  data packets at the receiver.

Abstract: The removal of arsenic, from aqueous liquids by adsorption  on  alumina,  is  facilitated by  selecting the alumina adsorbent to have a particle size below about 200 micrometres,  forming a slurry of the alumina and aqueous liquid and agitating the slurry.   It has been found that alumina can be selected to have a particle size sufficiently small,  or preferably a combination of both particle size sufficiently small and pore size and number sufficiently large,  to achieve 50 ppb or less arsenic within about 2 hours treatment.   The alumina with adsorbed arsenic  is separated from the slurry by steps preferably comprising microfiltration.    A  precipitation  pretreatment  can  be combined with the  slurry treatment  e.g.  to handle more concentrated solutions.

Inventor: HEIM ARMIN
IPC: E01B9/36
Filed: 1993-07-07
Abstract: ABSTRACT         Foot support modifications are required in the vicinity of rail attachment devices used in track systems.  The rail attachment devices are arranged on ties or appropriate track-retaining elements and have at least a sole plate (8), for example, a ribbed plate or only one shim without a ribbed plate, which is seated on the top of the tie or the like and is connected to this through carriage bolts or the like.  In order to achieve a non-tipping position of the railroad line, the rail foot support area (12) of the sole plate (8) or of the shim is provided only with flat bearing surfaces (15 and 16) that extend in the form of two strips and lateral sections (13 and 14) that are each associated to the two longitudinal edge zones of the rail foot, whereas the lateral section (17) that is located between them has a shaped face (18) that is set back relative to their common plane.  Even if the supporting surface of the rail foot of the railroad line does not coincide exactly with a proscribed standard plane but has a contour that projects convexly above this, a non-tipping position of the railroad rail on the sole plate or the shims is ensured by these measures.

Title: Motor drive circuit
Inventor: WILLIAMSON RALPH K
IPC: H02P7/00
Filed: 1993-08-27
Abstract: MOTOR DRIVE CIRCUIT            ABSTRACT OF THE DISCLOSURE    To improve the reliability and lower the cost of electronic  control  circuits  for direct  current  (DC) motors,  the need for external  mechanical  sensors  is eliminated through the use of low cost, highly reliable voltage comparator circuits.  A motor driver integrated circuit  provides  for  electronic  storage  of  data, automatic   execution   of   computer   programs,   and input/output transfer of various electronic signals used in the control of the DC motor.  The voltage comparator circuits sense the operating state of the DC motor by comparing the motor current sense voltage,  which is proportional to the torque of the motor,  to threshold fixed reference voltages to determine whether the DC motor is running normally or is stalled.   The motor driver IC stops or reverses the DC motor when it is stalled,  thereby preventing damage and providing for fully automatic operation without external sensors.
