Abstract: QUICK COOKING SEMIMOIST PASTA            ABSTRACT       A semimoist pasta product is prepared by uniformly dispersing a finely divided salt throughout a dough of wheat flour and water, partially gelatinizing the salt-containing dough, and then drying the gelatinized dough to a moisture content of at least 15% and an Aw of no more than 0.85. The dough, which can be made from wheat flour other than conventionally employed durum semolina, may also contain preservatives are color enhancing additives. The dough is formed into a pasta shape at any appropriate point after the finely divided salt is uniformly dispersed throughout the dough. The resulting semimoist pasta product is flexible, shelf stable and quick cooking.

Abstract: ABSTRACT           A dowel fastener for frictionally engaging the sides of recesses, bores or apertures in wood, metal, and/or plastic joint members to hold the joint members together is disclosed.  The dowel has a flexible, resilient, compressible tubular body with a spiral slot extending along its length. At least one end of the dowel is tapered and preferably includes inwardly angled, segmented, end flanges terminating in a circular, free end edge of smaller diameter than said body. The flanges lead the dowel into a reduced width or diameter recess or aperture upon assembly into a joint.  The opposite end may also be tapered for insertion in a similar recess or include an apertured, planar end preferably formed from bent end flanges for securing the dowel to a surface with a screw or other fastener.  Preferably, the diameter of the free end edge of the tapered end or ends is sized to prevent compressive insertion in an aperture or recess which is too small and would otherwise cause deformation or failure of the dowel.

Abstract: ABSTRACT OF THE DISCLOSURE           A steam generator includes a pressure vessel having two trays disposed one above the other on a generally vertical spindle.  One tray is electrically insulated from the pressure vessel and is connected to a power supply whip the other tray is electrically connected to the wall of the vessel itself.  Water can be pumped from a pressure vessel sump into the top tray.          The water flows in the form of a film from the top tray to the bottom tray and back from the latter into the sump.  In accordance with the invention, more than one pair of the trays is arranged one above the other such that the water from the bottom tray of one pair flows by way of a film from the bottom tray into the top tray of a lower pair and is allowed to flow into the sump only after having left the bottom tray of the lowermost pair of trays.  The invention provides a higher output for a given size of the tray or trays.

Abstract: ABSTRACT            The invention provides a seal for rails in a road level railbed comprising inner and outer resiliently flexible elongate members secured about each rail.  The seal members are contoured to fit snugly against the inner and outer sides of a rail and are provided with means accommodating rail spike heads.  The inner members have a groove to allow clearance of the flange of a railcar wheel and a flexible membrane extends beneath the groove.  Movement of the flexible membrane in response to the railcar wheel flange breaks up silt and detritus which has a tendency to settle and pack hard in the flange groove.  The movement of the flexible membrane also allows for deicing in the winter.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved method for producing a composite center electrode for a spark plug is disclosed.  The method comprises the steps of forming from a corrosion-resistant metal a cup having a closed end, walls extending upwardly from the closed end to an open end and a cavity extending concentrically therein, and then forming a composite billet having closed and filled ends by inserting into the open end of the cup a billet of a metal having a high thermal conductivity and fitting tightly within the cup walls.  The method also includes extruding the composite billet into an electrode blank having an upper headed portion and a lower portion of reduced diameter extending longitudinally therefrom.   The improvement comprises the steps wherein the positions and the relative sizes of the billet and of the cup are controlled so that the former fits tightly within the cup walls adjacent the closed cup end, but terminating short of the open cup end so that the cup walls extend thereabove at the open cup end, and the cup walls adjacent the open cup end are rolled radially inwardly to form the composite billet.  The method includes the additional improvement wherein the closed end of the composite billet is first inserted into a die having a stepped bore including an extrusion orifice of reduced diameter equal to that of a desired electrode head, and is then forced through the extrusion orifice to form an elongated composite billet.  The elongated billet is inserted into a second die having a stepped bore including an extrusion orifice of reduced diameter, wherein all except an upper headed portion is forced through the extrusion orifice to form the composite center electrode.

Abstract: ABSTRACT A heat exchange structure is constructed from refractory blocks having three linearly aligned flue-forming openings extending from top to bottom of the block. The central opening is surrounded on four sides by refractory and the two end openings are surrounded on three sides. These refractory shapes are assembled in an open basket weave structure to form the heat exchanger. The resulting structure contains vertically extending, interconnected flues of two types, (1) flues of a first type interconnected at alternate layers in the structure to each of the four contiguously adjacent flues and (2) flues of a second type connected to opposed pairs of contiguously adjacent flues at alternate levels and to the other pair of contiguously adjacent flues at the intermediate levels. The net result is a stable heat exchange structure with relatively thin walls, relatively large flues, and means for creating turbulence in gas passing through the exchanger, thus increasing the rate of heat exchange.
