Title: Tunnel distributed cable antenna system with signal taps coupling approximately same radiated energy
Inventor: ISBERG REUBEN A
IPC: H01R9/05

Granted: 1993-01-19
Abstract: TUNNEL DISTRIBUTED CABLE ANTENNA SYSTEM WITH SIGNAL TAPS   COUPLING APPROXIMATELY SAME RADIATED ENERGY     ABSTRACT    A distributed radio antenna system for extending radio communications into confined regions into which external radio signals do not penetrate, the system having separate transmitting (Tx) and receiving (Rx) antenna systems.  Each Tx or Rx system has an elongated low loss coaxial cable system (18 or 31) and a plurality of antennas (23 or 28) connected to each of the individual segments of the cable system at spaced distances along the length of the cable segment.  The antennas are coupled to the cable segments by signal taps (21 or 21') having adjustable or preselected values of attenuation so that the power fed to each Tx antenna (23) from the Tx cable system (18) is approximately the same and so that the attenuation of the signals received from each Rx antenna (28) is approximately the same, thereby conserving power and reducing system cost.  The Rx antennas (28) are located generally intermediate to the Tx antennas (23) so that spurious and intermodulation signals are substantially diminished by space attenuation.

Abstract: CONTINUOUS WASHED SAND FILTER AND WASHER     Sten F. Jacquet ABSTRACT OF THE DISCLOSURE     A sand filter is provided where dirtied filter media, generally sand, is continuously withdrawn from the filter container and lifted to the top of a juxtaposed separate wash vessel outside the container.  The dirty media cascades in zig-zag fashion across and down a series of vertically spaced inclined baffles in the wash vessel extending alternately from opposite sides of the vessel so that a thin, relatively wide media stream falls from one baffle down to the next.  A wash liquid, normally clean filtrate from the sand filter container, enters an inlet port adjacent to the bottom of the wash vessel and due to the coaction of the spaced baffles forms vertically-oriented circular flow patterns or vortices in alternative clockwise and counter clockwise directions so that portions of the wash liquid flow are directed to flow along with and in the same direction i.e. co-current flow, as the downwardly progressing and cascading media stream falling from one baffle member to the next baffle member.  During this co-current flow, dirt particles are displaced from the dirty media.  The cleaned media is returned from the bottom of the wash vessel to the filter container for reuse and dirtied wash water is removed from the top of the wash vessel.

Abstract: The power demand of a dynamic audio load (22) is monitored, for example, by sensing the voltage level of the power supplying the audio load (22). An audio load control signal (Val) corresponding to the power demand is generated. The audio load control signal (Val) is advantageously applied to a circuit (30) for producing a side pincushion correction current (im), for modulating the side pincushion correction current by the audio load demand. The audio load modulated side pincushion correction current (im) is used to modulate a horizontal deflection current (iY) in order to compensate for both side pincushion distortion and dynamic audio load induced raster width distortion. A filter network (R3,C5) may also be provided for removing high frequency signal components from the audio load control signal (Val).

Abstract: A method of and an apparatus for discharging containers of solubilized gas, e.g. acetylene, in which the gas is initially drawn as a preference stream from one container or group of containers (e.g. conventional acetylene bottles or tanks) and is fed to the consumer. When the pressure in the tank or tanks falls below a predetermined set point value, thereby indicating that the volume flow rate is less than the mean or average flow requirement, a second tank or group of tanks is connected to provide a complementary flow. The second tank or group of tanks supply the total requirement during replacement of the first tank or group and then forms the preference stream while the replacement tank or tanks of the first group provides the complementary stream.
