Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a process and equipment for the continuous treatment of solid substances in general, with specific applications for the gasification of coals and shales and direct reduction of iron ores.  The equipment comprises closed containers to which working pressure may be applied internally equipped with systems of deflectors which make them capable of the treating of solid substances in a continuous manner even when they are in the form of damp or clayey composi-tions, the said substances, are fed into the containers in moving beds or layers under gravity, in a downward direction, and are contacted with gases or vapors generated in the treatment per se and/or introduced into the containers and circulate co-currently or counter-currently to the solid substance flow. The equipment is especially suitable for the thermal treatment of said substances, releasing the gases and vapors from the layers, of any thicknesses, of said substances in the downward movement, provided with devices for the entrapment, contact and circulation of the gases released in the thermal treatment, and also suitable for the thermal treatment of said substances, mixed with other solid substances, to cause chemical reactions with same and/or with the circulating gases.

Abstract: Abstract of the Disclosure The crossover unit includes a polyurethane pad having a slot extending downwardly and then laterally or horizontally beneath an overhanging lip.  A wedge-shaped rubber insert or plug is received in the slot which not only closes the slot, but also resists deflection of the lip when heavy vehicles traverse the unit so that sufficient space is maintained beneath the lip for the protective accommodation of an electric power cable or hose.  In a second embodiment the slot extends in opposite lateral directions between a pair of overhanging lips, the insert in this instance being re-ceived between the two lips so that space exists under the lips for two cables or hoses.

When fabricating cans which are provided at their inner surface with a protective coating it is necessary, following the welding operation, to apply to the region of the welding seam the then missing part of the protective coating.  Prior techniques were unable to achieve any optimum application of the seam-coating which would reliably cover the welded seam.  If the fabricated cans are particularly intended for use for canned foods this then is dangerous to the health of the user.  With the apparatus of the invention the pro-tective coating is applied by means of a driven applicator roll to the welded  seam.  By suitably selecting the outer or jacket surface of the roll and a scraper  as well as the rotational speed of the roll it is possible to optimize application of the protective coating.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for dyeing foods with oxidation-sensitive natural colors is disclosed, wherein the food is adjusted, if necessary, to an SO2 content of a maximum of 30 ppm, and a pH value below 7.0, the food in enough water to cover the food is placed in a sealable container, substantially all air in the container is removed, and an oxidation-sensitive natural color is added to the container contents.  The container is then sealed, while maintaining air exclusion therefrom, and stored, preferably under ambient conditions.  During storage the food is exposed to the natural color in the container, and is dyed thereby.  Normally this ambient temperature dyeing step is acceptably complete within two weeks, or less.         The food can then be stored at ambient temperatures and sold in the container, directly to consumer.         The oxidation-sensitive natural colors, such as beta-laine, maintain their natural bright shades, without requiring special storage conditions, such as refrigeration.

Abstract: CONSTANT FLOW VALVE            ABSTRACT          A dispensing valve mechanism includes means for automatically maintaining a constant flow of fluid through a flow channel under varying fluid source pressure utilizes a piston movable within a chamber in response to fluid pressure to regulate the available flow area of a single outlet port in the chamber.  The piston is sized to permit fluid flow around the periphery of the piston, and may have an axial flow path therethrough to serve as the primary flow path through the valve mechanism.  A spring yieldably opposes axial movement of the piston that would tend to decrease the effective area of the chamber outlet port.  An adjustment screw is carried in the valve body for adjusting the force exerted by the spring.  The valve is particularly suited for use in liquid dispensing apparatus.

Abstract: Abstract of the Disclosure A low pressure throttle body injection apparatus for a spark ignition internal combustion engine includes an injector mechanism mounted above a throttle body having at least one throttle bore with a throttle controlling flow therethrough.          A valve controlled fuel injector is supported in a socket in the injector mechanism with its spray tip end positioned to inject fuel toward the throttle bore wall upstream of the throttle.  An annular fuel well is defined by an internal socket wall and the exterior of the fuel injector, that is in communication with the valve end interior of the fuel injector via injector side ports.          The injector mechanism defines a fuel inlet passage, including a fuel reservoir, opening into the fuel well and connectable to a source of low pressure fuel and a fuel return passage opening from the fuel well and connectable to the engine fuel supply tank.  A pressure regulator connected in the fuel return passage is used to regulate the pressure of fuel in the fuel well.  The injector mechanism further defines vapor flow passages for the flow of any fuel vapor from the fuel-inlet passage to the fuel return passage.  The amount of fuel entering the injector mechanism is substantially greater than the fuel discharge into the throttle bore by an amount sufficient to effect cooling of the injector mechanism so as to avoid substantial fuel vapor-ization at the fuel injector.
