Abstract: ABSTRACT      A solid fuel boiler has a facia for radiant heat to pass into a living room while the flue hopper, the flueways and ash pan are accessible from another room or out-building.  A dividing wall is shown.  By separating the radiant and aesthetic side of the boiler which is in the living room from the operating side, dust and dirt often associated with filling and emptying the boiler is confined to the other room or out-building. The flueway is relatively narrow which improves heat-transfer; this is possible because chimney sweeping can be done without having to pass brushes through the flueway.

Abstract: INTELLIGENT CONTROLLER     ABSTRACT OF THE DISCLOSURE     An intelligent controller provides a sophisticated communication processing link between a central processor and peripheral digital apparatus.  The intelligent processor pro-vides simultaneous read and write operations with the peripheral digital apparatus and performs extensive preprocessing on incoming data from such peripheral digital apparatus.  The in-telligent controller is comprised of three main sections:  the command processor, the device interface controller and the process sequence controller.  The command processor receives commands from the central processor, interprets them and transmits them to the device interface controller and to the process sequence controller.  The device interface controller communi-cates with the peripheral digital apparatus, providing data to that apparatus and receiving data from that apparatus, as well as commanding the apparatus to perform functions peculiar to the selected device.  Data is transmitted from the device interface controller to the process sequence controller whose function is to process that incoming data as commanded, to relieve the central processor of that task.

Abstract: METHOD FOR PREPARING POROUS METAL HYDRIDE COMPACTS     ABSTRACT OF THE DISCLOSURE    A method for preparing porous metallic-matrix hydride compacts which can be repeatedly hydrided and dehydrided without disintegration.  A mixture of a finely divided metal hydride and a finely divided matrix metal is contacted with a poison which prevents the metal hydride from dehydriding at room temperature and atmospheric pressure.  The mixture of matrix metal and poisoned metal hydride is then compacted under pressure at room temperature to form porous metallic-matrix hydride compacts.

Abstract: ABSTRACT OF THE DISCLOSURE A separator for separating plant stalks into components includes a feeder in the form of opposite endless conveyors which propel stalks against a splitter. The splitter comprises two oppositely traveling, notched bands which are in contact to define a cutting edge. Stalk sections have at least their pith removed by a milling roll disposed opposite a slower traveling hold-back belt, the latter controlling the speed of the stalk sections. The milling roll includes removable blades which are held in place by wedges and pairs of blades are adjusted by tiltable members at each blade end. The tilt-able members move the blades into contact with reference surfaces on the milling roll to define a proper blade location. Stalks are fed to the separator by being dropped onto a chute which guides the stalks into separate feed passages, the latter being maintained throughout stalk travel through the separator. The chute includes passage divider walls having cutters for separating partially cut stalks which may become hung-up thereon. The stalks travel to a spreader station at which vertically superimposed conveyor belts spread the stalks into a single layer. A method for releasing a stuck journal from a roll includes screwing an ejector bolt into an end of the journal until, in effect, it pushes off from a fastening bolt of the journal and against the journal itself to release the latter.

Abstract: ROGERS, BERESKIN & PARR                  C A N A D A     INVENTION:  CONNECTOR FOR GANGING CHAIRS INVENTOR:   JAMES HAYWARD              ABSTRACT OF THE DISCLOSURE    The invention relates to a connector for use in releasably joining chairs of tubular construction in side-by-side relationship to form straight rows.  The connector is constructed in two separate parts shaped to form a collar securable about a first tubular member used in the con-struction of the chair, and apertured to permit the connector parts to be secured to the tubular member with a bolt passed through the connectors and the first tubular member.  A first connector part carries a connecting element, either a tongue or a groove shaped to receive a tongue in interlocking engagement.  The second part is provided with a depression shaped to closely receive an end portion of a second tubular member of the chair and disposed about the aperture in the second connector part so that the threaded end of the bolt can be secured in the second tubular member.  The connector so constructed serves simultaneously to form a joint of the chair, joining for example a leg of the chair to a cross-bar or seat support member, and to mount the connecting element, so that the chair can be ganged with another chair provided with a corresponding element.

Abstract: Abstract of the Disclosure Disclosed is a coating bath and process for electrophoretically depositing a forging lubricant precoat on the surface of a titanium workpiece.  The specific resistivity of the coating bath is in excess of about 400 ohm-centimeters in order to retard simultanoues anodization of the titanium during the electrophoretic deposition process.  A high lead, moderate silicate, low alkali metal oxide frit is used in suspension in the bath.  Advantageously, the bath also includes an anodic electrocoating resin in colloidal dispersion in the bath. By controlling the degree of anodization and preanodization of the titanium, thickness of the deposited forgoing lubricant precoat can be closely controlled.

Abstract: OPTICAL FIBER FABRICATION AND RESULTING PRODUCT        Abstract Optical fiber preforms are produced by means of a duplex hot zone, a section of which is defined by an r.f. generated plasma fire ball.  The process operates within a tube with gaseous precursor material reacting within the hot zone to result in deposited material of the desired preform glass composition.  A "smoothing" region within the hot zone is defined by tube surface at a temperature sufficiently elevated to consolidate any particulate material resulting from reaction.  In some aspects, the disclosed procedures may be regarded as Modified Chemical Vapor Deposition.  Commercial significance resides in significantly increased throughput of preforms and, consequently, in fiber.

Abstract: ABSTRACT            The burner for metallurgical furnaces comprises a main combustion chamber       and an auxiliary combustion chamber presenting a plurality of outlet channels communicating with the main combustion chamber    . To the main combustion chamber there is fed in a pulsating manner a primary mix of fuel gas and air in stoichiometric ratio, and, during the intervals between the feed pulses, a secondary mix of fuel gas and air with a coefficient of excess air of 1.15 to 1.35 and at a rate fo flow corresponding to 1 to 3% of the nominal rate of flow. To the auxiliary combustion chamber      there is instead continuously fed an auxiliary mix of fuel gas and air with a coefficient of excess air of 0.65 to 0.85 and at a rate of flow corresponding to 1 to 3% of the rate of flow of the primary mix. The combustion products of the auxiliary mix stay in the auxiliary combustion chamber     for a very short time, more particularly for about from 0.005 to 0.01 sec., so that they still contain, when they enter into the main combustion chamber     , active chemical substances, and particularly hydrogen atoms and radicals containing hydrogen atoms.

Abstract: COLOR DISPLAY SYSTEM                         ABSTRACT     A projection and display system utilizes a modulated laser beam whose energy distribution in the "P" and "S" polarization planes is controlled by a half wavelength re-tardation plate.  The laser beam is then deflected along the X and Y axes and passes through a dichroic polarizer cube which splits the beam to focus upon a P channel smectic liquid crystal display cell and an S channel smectic liquid crystal display cell to selectively form images on one or both of the display cells.  At the same time, the formed images are projected by the use of light that is split into two colored light beams by a second dichroic cube and is reflected to back light the images in each of the display cells.  The projected beams then pass back through the first dichroic cube where they are recom-bined and passed through a projection lens system to a suitable display screen.  To selectively erase the informa-tion on either of the display cells, an AC bias is applied to that display cell during the laser scan thereof.
