Abstract: HEATING ELEMENT FOR ELECTRIC WATER HEATER                 ABSTRACT OF THE DISCLOSURE              The heating element has an outer connector assembly including a cylindrical threaded postion adapted to be threaded into a boss on the heater water tank and a sheathed heating rod which has at least one end secured to the connector assembly and which extends generally perpendicular to the heater tank centerline when installed. The heating rod is formed in a serpentine pattern, pre-ferably generally W-shaped, which provides the heating rod with an effective length greater than the inside diameter of the water tank, permits the heating rod to be inserted and withdrawn through the bore of the tank boss and permits the heater rod to be rotated, as the connector assembly is being threaded into and out of the tank boss, without striking any obstructions inside the water tank, such as the cold water dip tube, the hot water pipe and the anti-corrosion anode.

Abstract: ABSTRACT            This invention relates to a load distribution vehicle which is adapted to run on a rail track on or over a train of open topped cars for the purpose of loading the cars with particulate material such as mineral ore, broken rock, sand, granular food stuff or the like.  The vehicle consists of a bottom discharge hopper which includes a self contained power source for driving the vehicle on its rail track and opening and closing its load discharge doors.  The wheels of the vehicle are rotatable on verticle axes and are dish shaped to provide the vehicle with an abnormal transvers movement capacity on its track to enable it to negotiate sharp kinks in its track.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is directed to a biomass gasifier combustor which operates by gasification and combustion of the bio-mass to produce a clean effluent gas which can be used directly for grain drying or other applications where thermal energy is required.         This biomass gasifier combustor burns crop residue clean enough so that the combustion gases can be used directly for grain drying without the need for a heat exchanger to isolate the combustion gases from the drying air.  The biomass gasifier combustor includes a screw feeder tube having a screw feeder disposed therein.  The screw feeder forces the biomass into a first combustion chamber.          Primary combustion of the biomass produces a first combustion gas.       A venturi gas pump creates a negative pressure region in the gasi-fier, drawing the first combustion gas into a second combustion cham-ber.  A secondary combustion takes place, completely oxidizing the organics in the primary combustion gas and producing a clean exhaust gas which can be used directly for grain drying purposes.  An improv-ed first chamber includes a manifold section for preventing the bio-mass from escaping into the secondary combustion chamber, and a vari-able height grate for allowing the ash product to fall through the holes in the variable height grate.  A damper may be provided at the air inlets to control the flow rates or primary and secondary air.          A damper may be placed on the exhaust eductor or venturi pump for regulating the thermal output of the system.  The level of biomass in the first combustion chamber may also be monitored and automatical-ly controlled.

Abstract: ABSTRACT   A clamp structure consisting of a band for clamping a hose-like member onto a circular support.  The band is capable of contraction by means of an ear from a larger to a smaller diametric dimension without loss of its circular configuration and without any internal projections.  The structure is especially for use with relatively harder and thinner hose-like materials.  A gap in the band underneath the ear is covered off during contraction to prevent leakage thereat one end of the band consists of a tongue-like extension that can freely enter a centrally located recess in the other end, which is fork shaped, by means of relative circumferential movement of the ends.  This movement serves to change from the larger to the smaller diametric dimension while retaining a complementary configuration to the hose-like member.  The construction improves over the art by enabling reduction of the diametric dimension of the band without squeezing out any material of the hose-like object through the gap and without any step-like or other internal projection of the band.

In addition,  the automatic seat positioning device stores the positional data of the seat member set at the desired poisition from the counted value of the counter in a memory provided therewithin in order to return the current set position of the seat member to an originally set position on a basis of the stored data.  In this case, a memory correction circuit is provided which corrects  an erroneous stored data  to an accurate value corresponding to the actual position in response to the presetting of the counter according to the number of times by which a manual switch which energizes the motor in a normal or reverse direction is operated.   Therefore, the seat  member  can  more  accurately  be  returned  to  the originally set position.

Abstract: ABSTRACT     A container molded from a fluid permeable plastic material wherein the wall of the molded container is made resistant to fluid transmission.  A label has a barrier-coating resistant to fluid transmission and also has a heat-sensitive adhesive surface.  The label is applied to the container during the molding of the container.  The label is placed in the mold and then plastic heated to a temperature sufficient to activate the adhesive is intro-duced into the mold and forced against the wall of the mold and also against the label to form the container and at the same time to cause the label to adhere to the con-tainer thus formed.  The formed container has a side wall with abruptly curved portions at upper, lower, and spaced side edges of the label to provide the container with a generally continuous outer surface at the junctions of the label edges with the side wall.  The label becomes an integral part of the container and resists fluid trans-mission through the label area.
