Abstract: APPARATUS AND PROCESS FOR APPLYING ELASTIC BANDS                     ABSTRACT        A ribbon-like elastic element, under tension, is secured to  a  sheet of  relatively unstretched,  impermeable,  plastic material which defines the outer covering of a sanitary product such as a disposable diaper.  The securing is done by using a hotmelt adhesive, which is applied to the impermeable plastic sheet from a nozzle,  as the sheet moves beneath and closely adjacent the nozzle, The hotmelt adhesive extends, generally at an angle, between the nozzle and the plastic sheet, and a jet of cool air is discharged against that side of the adhesive material which subsequently contact the plastic sheet.  This reduces the temperature of the adhesive coming in contact with the  sheet  and  avoids  damaging the  sheet.   The ribbon-like elastic element is applied to the other side of the adhesive strip which has not been cooled by the jet of air.     BACKGROUND OF THE INVENTION         This invention refers to a process to apply, by sticking with hotmelt adhesive, elastic ribbon-like elements in tension on sheets of plastic material.        The invention is preferably applied to the manufacture of sanitary products, as, for example, disposable baby diapers or adult incontinence pads.        In these products, elastic elements in tension are fixed along the longitudinal edges of a sheet of impermeable plastic

Abstract: ABSTRACT OF THE DISCLOSURE:     In a method for the continuous casting of metal, in particular steel, in the form of strips or thin slabs, the molten metal is poured into a mould having cooled walls which move as the operation proceeds.  To prevent defects in the strand and interference with the casting operation and after the metal has flowed into the shaping cavity, contact between the cooled narrow sides of the shaping cavity and the fluid metal is caused to take place initially at a contact  face which represents only a fraction of  the particular distance between the two wide-side cooling walls. Furthermore, before reaching the contact face, the metal is cooled in a gap between the feed means and the wide side-wall engaging between the narrow side-walls,  the cross-section of the gap opening corresponding substantially  to the contact face.

Abstract: Abstract of the Disclosure A hinge type relay includes a yoke that supports an electromagnet.  The yoke has an upwardly extending portion that is located adjacent the electromagnet.  An armature capable of being magnetically attracted by the electromagnet when it is energized extends over the electromagnet.  The armature has on one side of the electromagnet a flexibly supported movable contact and on the other side thereof a member of non-magnetic material.  The latter extends downwardly toward the upwardly extending portion of the yoke, whereby the member is pivotably supported on the upwardly extending portion of the yoke, thereby forming a fulcrum for the armature.  The armature is biased away from the electromagnet when the electromagnet is not energized. By virtue of this construction, wiping of the fixed and movable contacts of the relay when they come together or separate from each other is achieved.
