Abstract: WALKING-BEAM BAND SEALER                        Abstract of the Disclosure A machine for sealing polyethylene bags or the like of the type having conveyer bands for gripping and transporting the bags to be sealed at a constant velocity from the machine's inlet end, through a heating station, then through a cooling station to the machine's outlet end. The conveyer bands are formed from a material having good release (non-stick) characteristics with respect to the fused thermoplastic. Disposed at the heating and cooling stations, respectively, are heating and chilling bars (heat transfer bars), each being disposed in pairs on opposite sides of and in proximity to the conveyer bands. Means are provided for cyclically opening and closing both pairs of bars relative to the conveyer bands and for translating the bars longitudinally in reciprocating fashion with respect to the moving bands. As bags to be sealed are carried along by the conveyer bands, the heat transfer bars pinch closed on the traveling bands, but since the bars at this time are being translated in the same direction of travel (forward stroke) and at the same velocity as the bands, no band wear occurs. Toward the end of this forward stroke, the heat transfer bars open relative to the bands and the return stroke occurs with substantially zero force between the moving bands and the heat transfer bars. During the return stroke, the bars act as a preheat device to warm up the film prior to the forward stroke to obtain greater speed. Because the bars are of a predetermined greater length than the length of the reciprocating stroke, a continuous package seal is ensured.

Abstract: METHOD OF FLASH BUTT WELDING              Abstract of the Disclosure In the course of flash butt welding of two parts, there are caused to continuously approach each other and the ends of the parts are fused by an alternating current. During the approach, an oscillatory motion along the  direc-tion of approach is imparted to one of the parts, thereby additional relative movements of the parts towards and away from each other are accomplished. The invention consists in that the welding voltage is reduced to within the range of 0.7 to 0 of its working value during the stage of a rela-tive movement of the parts being welded together away from each other and is restored during the stage of a rela-tive movement of the parts towards each other, reducing the voltage being carried out in a time interval of not less than 1/8 of the period of the oscillatory motion from the beginning of the relative movement of the parts away from each other, and restoring it, in a time interval of not more than 1/8 of the period of the oscillatory motion from the beginning of the relative movement of the parts towards each other. The voltage may be reduced to within the same range for the periods when the resistance across contacts exceeds a predetermined value.     The method of the invention is useful for welding together parts with both simple and complex cross sectional shape.

Abstract: ABSTRACT OF THE DISCLOSURE      A squeeze roll arrangement and method is disclosed for high expression squeeze roll liquor expression of non-woven fiber batts.  An auxiliary conveyor belt is provided to squeeze the batt before passing through the nip of the sqeeze rolls with the batt.  In this way, a portion of the liquor carried by the batt is expressed prior to passage of the batt through the nip.  Since the batt is carried by the auxiliary conveyor belt, disruption of the batt is minimized.  Preferably, chains are provided on either side of the batt to maintain a preferred orientation of the batt.  Various sprockets and pulleys are provided as desired to guide the chains with various turn rol-lers provided to carry the conveyor belt.  The chains are flexibly attached to the edges of the belt to continuously guide the belt.  In this way, alignment of the belt on the turn and squeeze rolls is maintained.

Abstract: ABSTRACT OF THE DISCLOSURE Roofs of buildings and the like are waterproofed by applying thereto a plurality of preformed, sheet-like, flexible waterproofing laminates each comprised of (i) a lower sheet support layer (preferably a plastic film or foil) non-removably adhered to (ii) an intermediate layer of waterproofing, self-adhesive, bituminous composition such as rubberized asphalt which in turn is removably adhered to (iii) an upper layer of protective sheet material (e.g. siliconized paper).  The surface of the lower sheet support (i) remote from the bituminous layer (ii) is non-adherent and the laminate is applied to the roof with such non-adherent surface adjacent the roof.  The uppermost protect-ive sheet layer (iii) is subsequently removed exposing the self-adhesive bituminous layer to which is thereafter applied a weathering layer (e.g. a coating of gravel).  The non-adherent surface nature of the lower sheet support layer allows any moisture entrapped below the applied waterproofing laminate to move and be distributed or vented.  The self-adhesive bituminous layer shields the underlying sheet support (i) from weather and sun, and functions both as a waterproofing layer and as an adhesive layer for the finally-applied weathering layer.  The inventive waterproofing method is ideally suited for use over roof decks which contain hydratable thermoinsulating concrete layers.

Abstract: POP UP ABRASIVE DISC DISPENSER                            Abstract The invention provides a container having a roll of abrasive adhesive discs releasably connected to a backing paper inside the container.  The container is designed such that the discs and backing paper may be pulled from the upper front of the container and when the backing paper is pulled downward or outward over the front edge the abrasive discs release from the backing paper and are popped free and released from the backing paper while being presented for easy removal by the user without contamination of the adhesive surface.  Alternatively, by pulling the backing generally upward from the device, the abrasive discs remain adhered to the backing paper and the backing paper can be cut or manually torn such that one or several of the discs may be pulled free from the device while remaining on the backing and removed to another work place for later use without risk of contamination of the adhesive backing.

Abstract: ABSTRACT          EXTRUSION OF COPPER         In a continuous friction-actuated process for the extrusion of copper, a passageway 3 is formed between an arcuate first member and a second member in the form of a wheel 1 having a circumferential groove 2 formed in its peripheral surface into which groove the first member projects.  The wheel is rotated and metal is fed into the passageway at one end and extrudes from the passageway through at least one die orifice 6 located in or adjacent to an abutment member 5 extending across the passageway at the other end thereof.  The abutment member is of substantially smaller cross-section than the passageway so as to leave a substantial gap between the abutment member and the groove. Particulate copper is first fed under such conditions that at least a substantial proportion of the copper extrudes through the clearance y between the abutment and the groove surface and adheres to the wheel until the copper so extruded forms a complete lining 8 in the groove, and thereafter copper rod is fed for the remainder of the extrusion operation.

Abstract: ABSTRACT OF THE DISCLOSURE:           Apparatus and method for forming hollow articles from plasticized materials are disclosed.  A preform is partially formed under substantially no pressure on a pre-form core by introducing the core into a void-free charge of plasticized material that is placed in a preform cavity from a source of the plasticized material.  After the pre-form core and preform cavity have moved together to define a preform mold space, the charge of plasticized material is subjected to a pressure forming step to form a completely packed preform on the core.  The preform is then blow molded in a blow cavity by introducing blowing gas into the preform through the preform core.  Neck mold structure that strips and releases the formed article from the core is also dis-closed.
