Abstract: ABSTRACT OF THE DISCLOSURE         A coil assembly for use in a communications system is essentially isotropic in a plane normal to the plane of the coil and includes two flat coils stacked one next to the other.        One coil is connected in series with a resistor in a closed loop and has a strip of high permeability material woven through it.  The other coil is tuned by a parallel capacitor across its coil terminals, such terminals being connected to electronic circuitry.  The coil is separated from the printed circuit board that contains the electronic circuitry by a sheet of high permeability material.  The assembly is self-contained and powered by a flat battery on which the circuit board is placed.          Another embodiment is disclosed that contains only one coil, the terminals of which are connected to a suitable electronic circuit, not shown.  Strips of high permeability material are disposed on both sides of the coil and an assembly is produced with a printed circuit board and a flat battery.

Abstract: DATA COMMUNICATION NETWORK AND METHOD OF COMMUNICATION            Abstract A local area network has a plurality of data stations 1 each connected to a common data channel 2 via a receiver 5, a transmitter 6 and a directional coupler 7, wherein, in order to resolve contention for the channel and at the same time providing each station with statistically an equal chance of gaining use of the channel, each station contends for use of the channel by transmitting, when the channel is free, transmission request signals in a sequence of consecutive time per-iods wherein in each time period the station either transmits a request or does not transmit a request according to a predetermined code.  If in any time period a data station 1 transmits a request but detects no transmitted requests by other stations, the station is permitted use of the channel 2.  If the station 1 does not transmit in any time period and another station transmits a request, then the station aborts contention.

Abstract: ABSTRACT OF THE DISCLOSURE      A pipe-welding assembly is provided in which single-pass welding of one pipe length to another is accomplished by gas lasers mounted to rotate around the axis of the pipes to weld the pipe ends together in the gap between two axially aligned spaced pipe clamps.  Weld-testing units are similarly rotated around the pipe axis.  The pipe-welding assembly is mounted on a gyroscopically-stabilised platform, which can be located on a pipe-laying land vehicle, or on a pipe-laying ship for laying pipe lines on the ocean bed.  If the ship is equipped with a pipe feed tower, with the pipe-welding assembly positioned at the base of the tower and a drawbridge provided for elevating successive pipe lengths angularly into the tower, pipe laying can be performed in the "J" configura-tion.  If the tower is mounted so that it can be inclined angularly into a position approaching the horizontal, and the pipe-welding assembly can be similarly rotated on its stablised platform, pipe-laying can be performed in the "S" configuration.

A method for forming the clip is also disclosed including cutting a configured tab in a metal blank and bending the blank.  The bending includes positioning the tab as a locking flange with is free end adjacent a narrower slot portion in a raised central portion.  The slot is defined by at least a portion of the outline of the configured tab.

Abstract: ABSTRACT OF THE DISCLOSURE           A system and process produce high actual levels of sulfur recovery from acid gas.  The system includes two conventional Claus reactors and two cold bed adsorption (CBA) reactors.  Four condensers are provided, one dis-posed before each of the catalytic reactors, and one dis-posed after the CBA reactor.  The system includes a gas clean-up treatment zone for hydrogenation, drying and oxi-dation of gas to provide stoichiometric ratio of H2S and SO2.  The gas is passed through the clean-up treatment zone prior to being fed to the first of the CBA reactors. The system is designed to operate either in a recovery mode or in a regeneration mode.  In the recovery mode, the reactors are in series and the CBA reactors are operated below dew point of sulfur.  In regeneration mode, effluent from the clean-up treatment zone is heated in a heat exchanger using effluent from the first catalytic reactor as the heat source.  The resulting regeneration gas is fed to one of the two CBA reactors to vaporize sulfur and regenerate the catalyst sulfur is recovered in the con-denser.  The effluent from the condenser is passed to the other CBA reactor which is operated in the recovery mode during regeneration.

Abstract: ABSTRACT OF THE DISCLOSURE         Single and multiple porous media impingement type air filter elements are disposed in filter housings which provide access to the filter elements from top opening doors or plenums in the housing for service or repair of the elements. Housing sections defining the plenums are provided with mechanism to lift and swing the housing sections clear of the filter opening, and the housing sections are movable to relieve excess working pressure differentials across the filter element. In two embodiments the filter elements are each in sealing engagement with a shield which is also sealingly engaged with a top wall or door of the filter housing to minimize contamination of personnel servicing or replacing the filter elements. Clean air is discharged through a downwardly extending clean air flow tube into a discharge plenum or chamber and particulate material separated from the air flow stream falls into a material collecting hopper portion which may be defined in part by a sloping wall separating the clean air flow chamber from the particulate material collection chamber. Filter element backflushing air control valves may be located in the bottom of the filter housing to enhance the accessibility of the filter elements from the top of the housing and to minimize overall height of the filter apparatus.
