Abstract: ABSTRACT OF THE DISCLOSURE         An improved purge unit is provided for establishing an enclosed zone around a weld area for retaining an inert gas.  The purge unit is particularly advantageous when welding a branch pipe or pipe connection to a main pipe or header.  The purge unit has a cone-shaped member which is inserted into an opening in the header through the branch pipe or connection and is the expanded to establish the enclosed zone around the inside of the weld area. An inert gas is then applied through the purge unit into the zone and the cone-shaped member is subsequently collapsed and withdrawn after the weld is complete.  An expandable tube is employed to expand the cone-shaped member and has a rod extending therethrough and connected to the member to provide greater stability for the purge unit.

Abstract: TITLE     MOVABLE FLOAT SYSTEM FOR BOAT LAUNCHING RAMPS            ABSTRACT OF THE DISCLOSURE           A float movable along a ramp for launching trail-erable boats so that the float remains adjacent the water line of the ramp responsive to changes in water level.  The float is moved by a line extending from the deep water end of the float, downwardly to a stationary underwater sheave, upwardly to a shore mounted powered drive mechanism and downwardly to the shallow water end of the float.  The drive mechanism is controlled by a water level sensor to move the float along the ramp as the water level changes so that the float remains in the water near the water line of the ramp as the water level fluctuates.  The water level sensor includes an ultrasonic level detector mounted in a vertical tube communicating with the water through an equalizing tube.  The float moves along a guide mechanism running alongside one end of the ramp to pre-vent transverse movement of the float.

Abstract: Abstract The existence of high fibrin-affinity uroki-nase is discovered by an isolation procedure using fibrin precipitated on an adsorptive-solid matrix. By the method described, the high affinity form of plasminogen activator can be isolated directly from urine or from kidney tissue culture medium.  The method is economical and provides a relatively high yeild of the activator.  The high affinity that this plasminogen activator has for fibrin is a property that makes it an improved thrombolytic agent and when radiolabelled provides a new diagnostic agent for the specific detection of fibrin thrombi through nuclear scanning.  The newly-isolated plasminogen activator has the following characteristics:  a molecular weight of about 56,000 Daltons, a specific activity of about 40,000 - 50,000 CTA units/mg, the appearance of a single chain structure and a high affinity for fibrin.

Abstract: APPARATUS FOR FORMING GLASS CONTAINERS          ABSTRACT OF THE DISCLOSURE           Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity.  Vacuum is applied to the neck area of the mold to form the finish portion of the con-tainer.  A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape.  During the transfer of the pari-sons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the parison.  The parison transfer mechanism carries the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the upright position at the blow mold or to help sustain the parison against collapse during invert.  The ability to apply puffing air to the parison during transfer is a significant step in the forming process.

Abstract: Abstract of Disclosure The invention relates to products and processes for employing heat stable enzymes especially--although not exclusively--for retarding the staling of baked and leavened cereal products.  A concentrated protective sugar medium is used to solubilize or disperse a fungal alpha amylase enzyme before it is incorporated in a dough.  This medium protects the enzyme against thermal denaturation, thereby enabling the enzyme to remain active during baking and until the starch of the dough becomes gelatinized and subect to enzyme attack.  A preferred embodiment of the dough also includes chemical emulsifiers which may be used in conjunction with the fungal alpha amylase enzyme dispersed in the concentrated sugar solution.  The invention addresses the conflicting requirements that enzyme activity must continue as long as possible throughout the baking process to retard staling; however, all activity must terminate before the end of the baking process to prevent the dough from becoming a sticky mass or paste.

Abstract: "SEED HARVESTER" ABSTRACT OF THE DISCLOSURE A seed harvester is provided for harvesting seeds from a standing crop without cutting the crop.  The harvester is particularly de-signed for harvesting grass seed.  The harvester includes a header assembly for stripping from the crop, and a seed separator for drawing the seeds from the header assembly in an air stream and for separating the seeds from the air stream.  The header assembly includes a frame assembly having a transverse inlet which communicates with the seed separator.  An endless revolving stripping surface is mounted across this transverse opening to contact the seed heads of the crop and strip the mature seeds from the crop. A rotating reel is mounted to rotate parallel to, and above and forwardly of, the seed stripping surface.  On rotation, the reel guides the crop into contact with the seed stripping surface and holds it there for a time to permit the seed stripping surface to remove mature seeds from the crop.  The seed separator includes a duct, curved between its ends.  The duct inlet communicates with the transverse inlet of the header assembly.  A blower is provided at the duct outlet to draw seeds in an air stream, from the header assembly and through the duct.  Baffles are provided across the curved duct section which, together with the curve in the duct, cause the seeds to move outwardly toward the outer wall of the curved duct section. This achieves partial separation of the seeds from the air stream. To achieve the remainder of the separation, the seed separator includes a seed with-drawal duct in the outer wall of the curved duct section, and a sealed con-tainer at the end of the seed withdrawal duct.  Air is drawn through the container and the seed withdrawal duct, preferably by the blower, to carry the seeds in an air stream into the container.

Abstract: ABSTRACT             A temperature stable bandgap voltage reference source utilizing two substrate bipolar transistors biased at different emitter current densities is provided.  Switched capacitors are used to input the Vbe and the .DELTA.Vbe of the transistors (NTC and PTC voltages, respectively) into an amplifier to provide a reference voltage VREF proportional to the weighted sum of the PTC and NTC voltages.  Proper selection of the ratio of the switched capacitors renders the reference voltage VREF substantially independent of temperature.  In a modified form of the reference, the reference amplifier is implemented by an auto-zeroed operational amplifier which uses switched capacitor techniques and an integrated capacitor to achieve the auto-zeroing function.
