Abstract: Methods of making modified polyimide/polyimide-amide foams and the resulting compositions. An N-substituted aliphatic imide is prepared by reacting a suitable aromatic dianhydride with a suitable oxoimine. A polyimide forming material is prepared by dissolving the N-substituted aliphatic imide in an esterifying solvent, then adding a suitable aromatic diamine. This material is dried to a powder or film. A foam is produced by heating the material to reaction temperature for a period sufficient to produce a stable foam. The material melts, then spontaneously expands into a foam which becomes self supporting and cures to a resilient flexible foam. Depending upon heating conditions, a polyimide, polyimide-amide or mixture thereof may be produced, resulting in foams having varying physical properties.

Abstract: High efficiency push-pull inverters minimize undesirable energy losses usually resulting from simultaneous conduction and imperfect switching of the transistor switching means. In each of the disclosed circuits, a saturable inductor and a diode are connected in parallel and across the base-emitter junction of each transistor. Voltage on the base of each transistor causes its associated saturable inductor to saturate, and the saturated inductor then terminates the flow of base current and provides a path for rapid evacuation of the charge carriers stored in the transistor base-emitter junction in order to render the transistor rapidly non-conductive. Each diode provides a drain path for current continuing to flow through its associated saturable inductor after junction evacuation. A novel triggering means initiates oscillation of the inverters.

F.), long retention times (1.5-4 seconds), and high pressures (300+psi) in a reactor having a controlled partial oxidation environment to thermally break the bonds of organic molecules into CO, CO.sub.2, H.sub.2, and acid gases (such as H.sub.2 S, HCN, HCL). In the preferred embodiment, pulverized coal, organic waste matter, and slurry water are pumped into the reactor vessel. The coal and waste matter are both broken into simple gases and the slurry water is split into hydrogen and oxygen. Downstream processing equipment removes particulates, acid gases, and CO.sub.2 making a product gas suitable for use as a fuel or chemical feedstock.

It thereby maintains the standard expression of the distribution of the load by iteratively correcting a roll opening on each of the rolling mills within the plate. The control of the load distribution among the roll stands is effected after the roll material has entered all of the roll stands.

Abstract: The invention provides an improved fish filleting board including an elongated body having a major top surface. A recess in the top surface defines a floor providing a minor support surface disposed below said major top surface (in the operational position of the board). This minor support surface is arranged to receive and support the head of a fish in approximate alignment with the spine of the fish after removal of the first fillet therefrom while at the same time the cut portion of the fish body lies flat on the major top surface with the spine thereof lying parallel to it. An abrupt step is defined between a portion of the top surface and the floor of the recess and against which the cut portion of the fish head may be lodged to stabilize the fish during removal of the second fillet. The support and stability afforded by the above recited structures enable filleting techniques to be used which result in a considerably higher yield insofar as the second fillet is concerned.
