Abstract: Abstract of the disclosure:          Now  water-soluble anthraquinone-azo compounds of the general formula   and their salts; in this formula the R1s both are sulfo groups, or one of the two is a hydrogen atom and the other is a sulfo group, R is hydrogen or lower alkyl and D, as the radical of a diazo component, is the benzene or naphthalene nucleus, which is monosubstituted or disubstituted by a fiber-reac-tive group Z, corresponding to the index n being 1 or 2, and which furthermore can be substituted by 1 to 3 substi-tuents selected from lower alkyl, lower alkoxy, halogen, nitro and sulfo.  The new azo compounds are very suitable as dyestuffs for dyeing fiber materials containing hydroxy groups or carbonamide groups, such as natural or synthetic polyamide fibers or polyurethane fibers and cellulose fibers, yielding deep dyeing and prints with very good - 1a -               HOE 78/F 163 fastness properties to wet processing and very good fast-ness properties to light.      The new compounds of the above formula are obtained by diazotizing a 1-amino-2-sulfo-4-(4'-aminophenyl)-amino-anthraquinone compound, which is substituted by sulfo in the 2'- and/or 5'-position, by means of an equivalent amount of sodium nitrite in the presence of a mineral acid, coupling this diazonium salt with an acetylsuccinic acid ester of a lower alkanol, cyclizing this radical of the coupling component to the pyrazolone ring and coupling the pyrazolono-phenylamino-anthraquinone compound, thus obtained, with a diazonium compound of an amine of the formula H2N - D - Zn D, Z and n being defined as above.  Up to the stage of the coupling reaction with the diazonium compound of the afore-mentioned amine, these reactions can be carried out as a "one-pot" reaction without intermediate isolation of inter-mediate products.

Abstract: ABSTRACT OF THE DISCLOSURE          A fluid-operated press comprises a crosshead, a bed,  four upstanding posts each extending vertically between each corner portion of the crosshead and each corner portion of the bed , and a slider disposed between the crosshead and the bed and slidably fitted on the posts to be slidable along the latter.  An upright wall structure located outside the slider and the posts is clamped between the crosshead and the bed  to enhance rigidity of the frame structure of the press.  The up-right wall structure has a wall portion surrounding at least that portion of the peripheral surface of each post which, as viewed in cross-section of the press through the upright wall structure, is positioned between two lines obtained by extending two adjacent sides of a rectangle which is formed by connecting the center points of the four posts.

Abstract: Abstract of the Disclosure A plate mounted between the carburetor and intake manifold having horizontally extending passageways and inlet and outlet ports communicating with four vertical apertures aligned with the passageways of the carburetor and intake manifold.  Double-walled tubular heat exchangers, formed of spaced apart outer and inner jackets, are disposed in the vertical apertures, the spaces between the outer and inner jackets communicating with the plate passageways and being sealed from the inside of the inner jackets, such that engine coolant can be circulated through such spaces and through the plate to cause pre-heating of the fuel-air mixture as it passes through the inside of the exchangers and into the intake manifold. The inner periphery of each inner jacket has ring shaped serrations and a downward taper, which,together with pre-heating by the heat exchangers, results in significantly improved vaporization of the fuel-air mixture.

Abstract: A B R E G E La fabrication d'un conducteur électrique isolé ou d'un tube comporte l'introduction d'un mélange de matières dans une extrudeuse et l'extrusion de ces ma-tières une fois homogénéisées et rendues fluides sur le conducteur électrique. Pour satisfaire aux prescriptions relatives aux câbles électriques, on utilise comme maté-riau d'isolation une polyoléfine telle que le polyéthy-lène dont on provoque la réticulation par l'adjonction d'un silane, d'un générateur de radicaux libres et d'un catalyseur de la condensation du silanol. Après l'extru-sion, la réticulation a lieu en présence d'eau. Pour fa-ciliter la pénétration de l'eau et activer la réticula-tion, le procédé prévoit d'utiliser comme additif supplé-mentaire, un agent de réduction du taux de cristallisa-tion du polymère par exemple l'acétate de vinyl.

Abstract: AIR FILTER                     ABSTRACT OF THE DISCLOSURE        A heavy duty automotive air cleaner for use in environments having high contaminant concentrations includes a housing carrying a vane-type centrifugal separator and a removable filter cartridge.  The removable filter cartridge includes a pleated paper filtering medium and a fibrous, depth-type filtering medium.  A pair of flow paths are defined through the housing between the inlet and outlet thereof.  One of the flow paths extends through the depth-type media and the pleated paper medium, and the other flow path extends through the centrifugal vane-type separator and the pleated paper medium.  The depth-type fibrous medium is placed upstream from the pleated paper medium, and is adapted to remove relatively fine particles from the incoming air stream as the heavier particles are centrifuged outwardly by the vane-type separator.

Abstract: ELECTRICAL INSULATOR AND    CONDUCTOR COVER            Abstract of the Disclosure An improved electrical conductor cover is provided which essentially completely surrounds an energized conductor and is resistant to inad-vertent, impact-induced dislocation of the cover during use.  The cover includes an elongated, tubular, conductor-receiving section and a pair of ribbed, normally biased-together legs extending from the section.  The legs normally are in abut-ting engagement, but can be separated for posi-tioning the cover on a conductor; the ribs are spaced along the length of the legs and serve to cooperatively maintain the conductor within the tubular section even in the event of an accidental impact normally tending to spread the legs and thus expose the covered conductor.  The cover also includes a molded-in-place, threaded head which projects only through the outer surface of the cover for allowing connection of a manipulative handle to the cover without the need for rivets or the like which extend completely through the insulative wall of the cover.

Abstract: P-305a     RECIRCULATING PROCESSING OVEN HEATER   ABSTRACT OF THE DISCLOSURE     A recirculating processing oven heater including a direct fired burner for heating processing gas for delivery to an asso-ciated processing oven.  A housing of the heater defines first and second parallel paths along which the gas flows between an inlet and an outlet thereof with the burner located along the first path to heat gas flowing therealong.  The housing also de-fines a junction of the two paths downstream from the burner.          The relative mass flow rates of gas flowing along the first and second paths is adjustable by a control valve mechanism including first and second adjustable valves at the inlet of the heater housing.  Each valve preferably includes a plurality of dampers and an adjustable actuator that positions the dampers.  The actuator for the first valve is power operated in response to the temperature of processing gas within the associated oven fed by the heater while the actuator of the second valve is manually adjustable.  An inner housing portion and an insulated outer housing portion of the heater housing have hollow elon-gated shapes with round cross sections and are arranged in a coaxial relationship such that the inner housing portion defines the first gas flow path and the space between the inner and outer housing portions defines the second gas flow path.  An upstream end of the inner housing portion receives the burner while a downstream end thereof mounts a conical mixing member for causing mixing of the gas from the two paths within a mixing chamber defined by the outer housing portion adjacent the downstream end of the inner housing portion.  A wall extends between the inner and outer housing portion at a P-305a location between the control valves to separate the gas flow paths adjacent the inlet.  An adjustable fresh air inlet in the outer housing portion, annular baffles along the first and second gas flow paths, and a blower within the outer hous-ing portion downstream from the mixing chamber cooperate with the other components of the heater during its operation to pro vide efficient heating of processing gas for delivery to the oven.
