Abstract: ABSTRACT OF THE DISCLOSURE           An improved defroster arrangement is equipped in a known refrigerating showcase provided with  an inside duct for circulating a refrigerated air flow to refrigerate the interior of the showcase and an outside duct for circulating a low tem-perature air flow to prevent a temperature rise of the refriger-ated air flow in juxtaposition.  The improvements exist in the provision of communication means between said inside and outside ducts, and gate means for opening and closing said communication means.  Upon defrosting the gate means is actuated to communi-cate the inside and outside ducts to each other through the com-munication means and also to block the path through the outside duct between the communication means and an intake port.  Thereby not only the air circulating through the inside duct upstream of the gate means and through both the inside and outside ducts downstream of the gate means that is driven by means of fans dis-posed within the inside and outside ducts, respectively, but also an ambient air may be jointly sucked into the inside duct up-stream of the gate means.

Abstract: CHIP THICKNESS CLASSIFIER                   ABSTRACT OF THE DISCLOSURE          A chip thickness classifier comprising a drum mounted for rotation about its longitudinal axis and having its periphery formed by a plurality of discrete longitudinally extending bars of elongated cross-section. The bars are arranged in substantially shingled relation-ship with one side of each bar spaced closer to the axis of rotation of the drum than the other side of the bar thereby to form outlet passages between adjacent bars.  The outlet passages are substantially axially extending slots having their major width dimension measured substantially radially of the axis of rotation of the drum.  Each of said bars is mounted for rotation about a longitudinally extending axis of the bar and the bars are interconnected by an adjustment mechanism that applies simultaneous incremental movement to stepwise rotate said bars and change said width dimension of the outlet passage.  The drum is rotated in the direction wherein the side of each said bar closest the axis of ro-tation of the drum leads.

Abstract: METHOD OF MINING FLAT-DIPPING AND SLOPING      BEDS OF A MINERAL WITH HYDRAULIC EXCAVATION     ABSTRACT OF THE DISCLOSURE    The method of mining flat-dipping and sloping beds of a mineral with hydraulic excavation includes dividing the bed being mined into levels and sublevels. The height of the sublevels is determined by the rock geology of the bed formation. The sublevels, in their turn, are subdivided into blocks, the width of each block being short of the li-mit length of the steady or self-supporting outreach of the cantilever of the rock of the main roof with the given pattern of cutting into the bed with the cutting drifts and holes defining the short working faces. The spacing of the blocks being worked in the upper and lower sublevels in the direction of strata is set to preclude inter-influence of the bearing rock pressure in the blocks where the stoping work is being done. The method enables to conduct stable excavation of the mineral over an extended front of stop-ing.

Abstract: R/W ARM THAT PREVENTS CATASTROPHIC FAILURE   ABSTRACT         In a flexible magnetic disk file having one or more flexible disks mounted for rotation about a centrally located axis, data on a selected disk is transduced by a magnetic head seated on a fail-safe head arm support.  The head arm support is a relatively flat elongated member mounted at one end to a carriage assembly.  The head arm support has a smooth contour with relatively sharp edges about its periphery and a spherical enclosure seated on its free end.  The head arm support is tapered, at a predetermined angle from the rigidly mounted end towards the free end.          The angle of tape allows for automatic ejection of the head arm support from the disk file during inadvertent closure of the disk file.  The relatively sharp edges allow the head arm support to open a closed disk file.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and an arrangement for the sealing of a cover strip onto packing containers, in particular non-returnable containers for liquid foodstuffs, which containers are of the type which is manufactured from laminated material comprising layers of, among others, thermoplastics.     Packing containers of this type are generally provided with an opening arrangement in the form of a pouring opening punched out in the top side of the container, which is covered by a tear-off cover strip.   The cut edge extending around the pouring opening is in this case situated inside the container which makes necessary special measures in order to prevent the occurrence of bacteria-collecting corners and pockets.   This is a problem in particular in the relatively thick type o-f packing laminate which comprises layers of foamed thermoplastic material.          It is often also necessary to seal off the free cut edge, since the laminate occasionally comprises layers which for various reasons must not come into contact with the contents.   The difficulties are overcome in accordance with the invention in that the thermoplastic layers in the edge areas of the laminate adjoining the pouring opening are melted and made to flow over the edge and are joined on the one hand to one another, and on the other hand to the side of the cover strip facing towards the package.   This is achieved by simultaneous heating and compression of the actual material area with the help of a mandrel subjected to ultrasound and a holding-up tool.

Abstract: ABSTRACT OF THE DISCLOSURE         During manufacture of the draft gear and before it is inserted into the railway car, the piston is positioned in the cylinder in a preshortened position.  Part of the fill of flowable, normally solid material is inserted into the cylinder about the piston rod to hold the piston in the preshortened position and the remainder of the fill is inserted between the piston and the closed end of the cylinder.  The part of the fill inserted about the piston rod may be in the form of a collar or in the form of particulate material introduced through a port radially opposite the piston rod.  This holds the piston in the preshortened position so that the draft gear can easily be inserted into the railway car.  After the railway car is put into service the part of the fill about the piston rod breaks down and the piston returns to its normal operating position.
