Abstract: ABSTRACT     A bandpass filter having a plurality of cascaded wave-guide cavities has inter-cavity coupling means.          One or more of the cavities is rotated relative to an input reference mode thereby causing quasi-orthogonal coupling structures to be introduced into said cavities.          The rotation of one or more cavities enables symmetric or asymmetric amplitude and phase responses to be produced as desired.  In previous filters, the asymmetrical characteristic of the phase response could not be controlled without destroying the equi-ripple character of the passband response.  The filter can be used in channel multiplexers for satellite communica-tion systems.     r

Abstract: ABSTRACT            Title:  Molecular Sieve Type Gas Separation Systems A molecular sieve type gas separation system capable of delivering oxygen-enriched air by increasing the oxygen content of air fed to the system has control means including a valve arrangement associated with each sieve bed for cyclically subjecting each bed to a charge/adsorption on-stream phase followed by a purge/desorption regeneration phase.  During the regeneration phase of each sieve bed the gas pressure in the bed at least substantially equals the ambient atmospheric pressure or a pressure related thereto such as the ambient pressure of an outlet to which the oxygen-enriched air is being delivered and, for a predetermined range of outlet ambient pressure, the overall cycle time and the relative durations of the phases are fixed at values such that the oxygen content of air delivered by the system remains within physiologically acceptable limits for breathing.  In application of the system to an aircraft for supplying oxygen-enriched air to aircrew, the outlet will generally comprise one or more oral - nasal breathing masks and during the regeneration phase the beds are preferably opened to the ambient atmospheric pressure of the aircraft.

Abstract: ABSTRACT OF THE DISCLOSURE          A self-propelling bevel fusion-cutting machine for beveling pipes comprises a machine main body which holds a fusion-cutter, such as a burner, for effecting the bevel fusion-cutting of the end face of a pipe, traveling guide rollers which roll on the pipe end face, and outer roller which rolls circumferentially on the outer peripheral surface of the pipe, and an inner roller which rolls circumferentially on the inner peripheral surface of the pipe.  The machine main body is movable along the pipe end face by means of these rollers.  The outer or inner roller is removably pressed against the peripheral surface of the pipe and this roller or the other roller is connected to a drive source mounted on the machine main body so as to be thereby driven for rotation.  The axis of rotation of the rotatably driven roller is inclined along the movement direction of the machine main body, so that with rotation of the driven roller the machine main body is capable of moving circum-ferentially along the pipe end face while holding the traveling guide roller in intimate contact with the pipe end face.

Abstract: ABSTRACT OF THE DISCLOSURE A sun heating equipment has a sun collector with an upwardly-directed hollow tightly-closed absorbing plate provided with an inlet and an outlet.  The plate comprises two panels secured at their edges and having depressions extending in a first direction over part of the plate width to form flow channels connecting the inlet with the outlet, the inner walls of the plate being moistenable at least in the location of the flow channels.  A line for fluid connects the outlet to the inlet and heat-transfer fluid in the line and the flow channels vaporize at the temperature reached within the flow channels.  A heat exchanger comprising a condenser has a vacuum pump directly mounted in the line between the condenser and the inlet means. A venting cylinder is provided between the vacuum pump and the inlet and a distributing device extends perpendicular to the flow channels and feeds the fluid in liquid form with a limited flow rate to the flow channels, so as to have the moistenable walls regularly irrigated at least at the top with a thin film of liquid fluid.  A flow control device between the venting cylinder and the outlet means lets through a flow rate which can be vaporized in the absorbing plate with a determined sun radiation so that the fluid does not fill the flow channels and is vaporized at least for the most part before reaching the bottom of the absorbing plate.

Abstract: Abstract Of The Disclosure An electricity metering transducer is disclosed which samples voltages and currents at an innerconnection terminal (10) of an electrical energy distribution system, converts those samples to digital form and computes selected electricity metering quantities.  In a multiphase system current and voltage signals are multiplexed to a pair of codecs (24 & 26), one for current signals and one for voltage signals.  The period of the signals being sampled is detected and used to generate a substantially nonsynchronous sampling signal so that a sample migration system is created which provides a large number of samples of a composite waveform.  The steps of a digitally generated stepwise approximation of a sawtooth waveform are summed with the sequential analog samples and then removed from the digital value of each sample by software operation in order to increase the resolution of the digital to analog conversion.

Abstract: ABSTRACT OF THE DISCLOSURE                   TEXTILE MATERIALS AND THEIR USE IN CONTAINERS    A fabric having anti-static properties being formed from a first woven layer of polymeric fabric, a second woven layer of polymeric fabric which contains spaced threads of staple metal fibres and an intermediate layer positioned between the first and second layers to form a moisture barrier.  In its most preferred form the woven polymeric fabric is formed of woven polypropylene and the spaced threads of staple metal fibres are formed of staple stainless steel fibres carried on a central core of a synthetic material. The fabric is of particular use in the manufacture of intermediate bulk containers where it is believed is advantageous in permitting corona discharge at a very low voltage of static electricity thereby preventing any dangerous build-up of voltage which subsequently is discharged by a spark.

Abstract: ABSTRACT OF THE INVENTION         A  voice-controlled  elevator  security  system.          Access  to  an elevator  system  servicing a plurality of landings of a structure is controlled by comparing a voice signal of a potential user of the elevator system with stored voice signals of all authorized users.  The compar-ison is  accomplished by first digitizing the potential user's voice signal  and comparing it,  on a bit-by-bit basis, with a digital representation of the voice signals of all authorized users.  If the comparison satisfies an established criterion, the potential user is determined to be an authorized user.  Once this determination has been made,  the authorized user can initiate car call signals for those landings to which the authorized user is per-mitted access.  An authorized user can also temporarily modify the previous digital representation of the voice signal when the authorized user is suffering from laryn-geal indisposition.

Abstract: LEACHING AND WASHING A FLOCCULATED  SLURRY HAVING A FIBER CONTENT                       ABSTRACT     Particlized mineral material, such as gold ore, silver ore, or coal, is subjected to a leaching process in a manner to maximize treatment effective-ness even when the particlized mineral material contains small fines.  The material is slurried with a flocculating material and fibers, such as cellulosic fibers, fiberglass fibers, or ceramic fibers, and a liquid, and then is passed to the top of a leaching reactor.  The slurry is continuously passed downwardly in the reactor while the leaching liquid, such as a cyanide solution, is passed counter-current to the slurry.  Leaching liquid is removed from the top of the leaching reactor by a stilling well, and then passed through a carbon adsorber and reintroduced into the reactor.  Leached slurry is passed to a continuous washing station, with spent wash liquid from the top of the washing station being utilized as a slurrying liquid for the particlized mineral material.
