Abstract: ABSTRACT OF THE DISCLOSURE            A process for separating SO2 from a current of gas containing the same, at least intermittently, in a concentration which is permissibly high for discharge into the ambient atmosphere, with attendant production of sulfuric acid by the nitrogen oxide process is described. In the novel process, the SO2-containing gas initially flows either through a denitration zone, or through a pretreatment  zone constituting a first sector of an SO2-processing zone, and then through the said denitration zone, thereafter through the main sector of the SO2-processing zone, and subsequently through a nitrogen oxide absorption zone, the current of the gas being brought into contact in at least one of the two sectors of the SO2-processing zone with dilute acid (less than 70% by weight of H2SO4)  which is circulated through the respective sector of this SO2-processing zone, whilst in the absorption zone the nitrogen oxides released in the denitration zone are absorbed by sulfuric acid, and nitrose-containing acid having a H2SO4-concentration of 70 to 80% by weight is drawn off from the absorption zone and fed into the denitration zone. The novel process further comprises (a) measuring the content of NO in the current of gas at a point in the absorption zone or downstream of the absorption zone or simultaneously at points both in the absorption zone and downstream thereof, and (b) introducing a nitrogen-oxygen compound, or a sub-stance which contains such a compound, into the dilute acid cycle of at less one of the two sectors of the SO2-processing zone when, at the NO-control point or points, a specific limit value of the NO-content or of the steepness of an increase per unit of time of the NO-content in the current of gas is exceeded, while abstaining from altering the acid concentration in the absorption zone,

Abstract: ABSTRACT OF THE DISCLOSURE            A process and apparatus for the production of intermediate hot metal suitable for further refining into steel is disclosed.            The basic process includes the steps of heating a charge of ore in a reducing furnace having a reducing atmosphere therein comprising a mixture of reconditioned and recycled top gas from the reducing furnace and off-gas rich in hydrogen and carbon monoxide produced by a cupola melting unit to reduce the ore to iron, partially carburizing the reduced iron in the reducing furnace with carbon-containing off-gas produced by the cupola melting unit, and melting the reduced and carburized iron together with scrap, slag forming additives and fluxes in a cupola melting unit having a reducing atmosphere therein produced by the combustion of a rich fuel/oxidant mixture to form a molten slag and molten iron suitable for the further refining to produce steel.  The process contemplates the further refining of the molten iron from the cupola in an electric steelmaking furnace or an oxygen steelmaking converter.  In an alternative form of the process, the reduced and carburized iron is cooled within or outside the reducing furnace to form a prereduced metal pellets suitable for use as a part of the burden in a melting unit.            The apparatus comprises a refractory lined cupola melting unit portion equipped with burners capable of burning a rich fuel/oxidant mixture to produce a reducing atmosphere within the melting unit and off-gas rich in gaseous reductants, a direct reducing unitportioncommunica-ting with the upper end of the melting unit to receive the melting unit off-gas recirculating and conditioning means to recycle at least a portion of the top gas from the upper region of the reducing portion to the lower region of the reducing unit portion, means for introducing ore into the direct reduction unit portion of the apparatus, and means for introducing additives and fluxes into the melting unit portion of the apparatus.

Abstract: Robert L. Alldredge UPFLOW SAND FILTER WITH SUBSTANTIALLY   IMPERFORATE HOLD-DOWN DIAPHRAGM                 ABSTRACT OF THE DISCLOSURE An upwash, upflow, graded sand filter has a reusable imperforate diaphragm on the top of the graded filter media and an inlet for pressurized fluid above the diaphragm for inflating the diaphragm against the media during filter stage. The filter housing is flared upwardly and outwardly at selected portions to reduce the velocity of upflowing liquid during wash stage for improved grading of the filter media.  A natural foraminous layer may be self-grading at the top of the filter media, allowing a circumferential outlet for filtrate.  A layer of fine, dense filter media may also be used to increase the size range of media particles in the filter.  Special diaphragms may be composed of individual leaflets that float above a dirty-liquid outlet during wash stage, but that sink due to a change in density when the filter is pressurized for filter stage.

Title: Broadband frequency divider  in waveguide
Inventor: HARRISON ROBERT G
IPC: H03K23/00
Filed: 1979-04-05
Granted: 1982-05-11
Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to a broad bandwidth frequency di-vider which converts a band of input frequencies into a band of output frequencies such that each output frequency is one half the corresponding input frequency.  The frequency divider has a first rectangular waveguide which propagates the band of input frequen-cies and a second larger rectangular waveguide which propagates the band of output frequencies.  The two waveguides are orthogo-nally disposed with respect to one another and are interconnected by a slot provided in a common wall.  Two nonlinear capacitive reactances are mounted in the first waveguide, one on each side of the slot, forming a transverse resonator.  When the two nonlinear reactances are pumped in phase at the input frequency, parametric subharmonic resonance can be excited transversely at one half the input frequency such that the nonlinear reactance voltages are 180 out of phase at the output frequency.  A corresponding subharmonic voltage developed across the slot is coupled directly into the output waveguide.  The symmetry of the arrangement isolates the input frequency from the output port whereas the low-frequency cutoff property of the first waveguide isolates the output frequen-cy from the input port.  An arrangement is provided for biasing the nonlinear capacitive reactances.

The enlarged catheter end is positioned within the  relatively enlarged portion of the bore, while the adjacent portion of the catheter is positioned within the relatively constricted portion of the hub.  A rigid tubular funnel fits within the bore of the catheter.  As a result of this the collapse and subsequent passage of the en-larged catheter end through the relatively constricted portion of the hub is prevented.
