Abstract: Abstract of the Disclosure An integral phase shifting network of a transmitter filter provides a means to reduce the size and increase the efficiency of an antenna coupling network.  The network to shift the phase of the transmitter filter is printed by depositing conductive material directly on a ceramic block using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications.  By utilizing an integral phase shifting network, either transmit or receive filters having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.

Abstract: Abstract of the Disclosure A dust filtering and collection system for filtering dust particles from an incoming dust laden air stream is disclosed.  When used in a mobile vacuum loading/unloading vehicle, the system separates dust particles from the incoming dust laden air stream in a dust filtering and collection canister or chamber and then exhausts the dust cleansed air stream from the canister or chamber.  Dust particles filtered from the dust cleansed air stream are collected as accumulated product particles along a bottom area of the canister or chamber.  The accumulated product particles may then be transferred to a storage chamber from which the incoming dust laden air stream has emanated.  In addition, the dust filtering system of the present invention includes a plurality of juxtaposed hollow polymer tubes which are suspended and supported by a transverse panel extending across the canister or chamber adjacent an upper end thereof, with each hollow polymer tube being sealed relative to the transverse panel and having a porosity permitting air to be drawn therethrough while removing dust particles from the incoming dust laden air stream.  The construction and arrangement of the hollow polymer tubes, within a dust filtering and collection canister or chamber, provides a highly efficient, continuously operating, self-cleaning filtering system, for use in mobile vacuum loading/unloading vehicles or in other industrial filtering systems.

Abstract: The invention relates to a synchronization method for radio transmitters of a local, e.g. nationwide paging network. A paging network is connected to a public switched telephone network and comprises a paging network unit (PNU), transmitter group controllers (TGC) and transmitter site interfaces (TSI). All controllers are provided with means for receiving, processing and transmitting messages in digital form. Base stations are provided with radio transceivers (Tx, Rx) transmitting radio signals intended for paging or for synchronization of the base stations covering a common overlap area. With the method of the invention, synchronization is performed on the basis of a synchronization plan composed by paging network unit (PNU) and synchronization commands based on the plan. Synchronization proceeds sequentially in a certain order so that each base station (except for the initiator) first receives and then transmits a synchronization signal. Prior to the transmission of a synchronization signal, compensation of delays is executed based on one hand on receiving own transmission and, on the other hand, on information given by the paging network unit PNU about distances between base stations. The synchronous transmission of paging information is confirmed to be independent of a digital data transmission network by determining the exact time of radio transmission of each page according to a plan made beforehand by the paging network unit.
