Abstract: A B S T R A C T      A device for the program-controllable exchange of injec-tion molding dies and for the continuous preconditioning of an injection molding die prior to and during its insertion in-to the die closing unit of an injection molding machine, com-prising a translation table with two die emplacements which are alternatingly movable into transverse alignment with the die clamping space, for transfer of a die assembly by means of an endless roller chain with drive pins and a drive rack entraining the die assembly.  Each die emplacement has a cap-tive drive rack which carries a coupling head for flexible temperature conditioning lines and each die assembly has a matching coupling head with coupling valves and an identifica-tion code incorporated in a multi-conductor connection, all connections being established by the mere lowering of the die assembly onto its die emplacement.

Abstract: Abstract of the Disclosure Photographic elements and assemblages are described employing positive-working redox dye-releasers, wherein the element contains an oxidant which is located between the support and the photo-sensitive portion thereof.  The oxidant has an electrode potential of from about -200 mV up to about 1200 mV versus a saturated calomel electrode at a pH of about 5 to about 6.  After processing, the oxidant reacts with the electron transfer agent to prevent it from reacting with the dye releaser which would otherwise cause further dye release.  The reduced form of the oxidant is then substantially incapable of reducing the positive-working redox dye-releaser. Dmin stability is thereby improved.

Abstract: ABSTRACT OF THE DISCLOSURE A compact, self-cleaning, cabinet, dust collector is provided.  The collector housing is a single-piece, molded unit having recessed areas and a molded air inlet. Entering dust-laden air is directed into two flows in a passageway surrounding a suspended, flexible, pleated filter element.  An inner wall of the passageway contains a precleaner upstream from the filter element.  A collector ramp, at the bottom of the passageway, directs pre-cleaned matter to a removable hopper.  A fan, supported above the open upper end of the filter element draws air through the collector.  A fan motor is isolated from the housing interior in one of the recessed areas of the housing.  To gain access to the filter element the fan is rotated upwardly and away from the filter element.  To prevent the pleats of the element from collapsing, hot-melt spacers are provided on the pleat surfaces.  The element is flex-cleaned by a rotatable mechanism located beneath and adjacent the bottom closed end of the element.  The mechanism causes a lifting and twisting of the element and includes an isolated motor, a rotatable arm with wiper blades, and ramp lugs on the bottom end of the filter element.  The released dust is swept into the hopper by the wiper blades.  A removable double-walled cover is secured over the fan.  Filtered air is released from the collector through louvered openings in the cover. Transistor logic and various sensors are used to control the operation of the collector.

Abstract: Abstract A valve fitment (3) for a two-chamber compressed gas packaging means with product components in an inner and an outer container (1, 2) for mixing thereof in the outer container (1) before discharge of the mixture has a discharge pipe (6) which is sealingly axially displaceably guided in an opening (17) in a cover (7) of the outer container (1), which is smaller than the outside diameter, for simultaneously piercing a wall portion (5) of the inner container (2), and a valve (11, 14) which is actuable to release the mixture. In order to ensure that discharge cannot take place before the mixing operation, the cover, for coupling the inner container in position, internally carries a coupling means (8) which is disposed around the discharge pipe and which has product through-flow openings (23, 27), wherein the valve can be actuated by displacement of the discharge pipe from the outer limit position in which the valve is closed, by way of an intermediate position in which the wall portion of the inner container is pierced and the valve is still closed, into the other limit position in which the valve is opened.

Abstract: ABSTRACT OF THE DISCLOSURE    The residues obtained in the hydrogenation of oil, especially heavy oil, or of coal are subjected to low temperature carbonzation in a drum, preferably a rotary drum, at temperatures of 400° to 600°C, whereby a carbonization gas after the separation of the condensable portions and heating to about 600° to about 950°C is introduced into the low temperature carbonization drum.  The gas is heated to temperatures of about 600° to about 950°C indirectly by flue gases developed during the combustion of oil or gas, for example, of excess carbonization gas.  The residue to be carbonized at low temperature is introduced into the hot gas in a finely dispersed state and preferably atomized.

Abstract: TWO PART WHEEL BRACKET ASSEMBLY    AND A METHOD OF MAKING IT                ABSTRACT OF THE DISCLOSURE    A wheel bracket assembly includes two separate, platelike bracket parts which each have a noncircular opening therein and are disposed on opposite sides of a wheel in angular alignment.  The ends of the axle for the wheel extend through the noncircular openings and the bracket parts are fixed against axial and rotational movement with respect to the axle.  A method of making the wheel bracket assembly includes the steps of stamp-ing out from at least one metal plate the two bracket parts which are substantially mirror images of each other and have the noncircular opening therethrough, placing the bracket parts in angular alignment on opposite sides of the wheel so that the ends of the axle extend through the noncircular openings, and upsetting each end of the axle to retain the bracket parts in place and so that the material of the axle flows to fill the noncircular openings in the bracket parts and thereby prevent relative rotation of the bracket parts.

Abstract: Abstract:    An extensible drinking straw includes outer and inner parts.  When extended, an enlarged-diameter portion formed at an end of the inner part slides within the outer part and engages a narrowed-diameter portion formed at an end of the outer part.  This prevents the inner part from separating from the outer part.  Even if the parts are slid in the opposite direction or the inner part is pushed into the outer part, they are prevented from separating by the fact that the projecting end of the inner part has an expanded-diameter portion.  Alternatively, this result can be achieved by forming the end of the outer part located opposite its narrowed-diameter portion as a further reduced-diameter portion.  In addition, an inwardly protruding portion is formed on the outer part to lock the inner part in position when the straw is in its extended state.
