Abstract: INTERIOR CORE PROTECTOR            Abstract of the Disclosure An interior core protector for protecting the interior of a coil of material, e.g., coiled sheet steel, from damage is disclosed.  The core protector includes a pair of overlapping formed angular paperboard members each having a series of spaced die cuts in one leg thereof permitting the angular members to be bent to conform to the inner diameter of the coil.  The cuts in one leg are offset from the cuts in the other leg such that when the protector is bent for placement in the interior core of the coil and the width of the cuts increases, a paperboard segment of one member nevertheless overlies the cut in the other to provide protection for the material about the full circumference of the interior core.  The core protector is characterized in part by economies of materials used, economic use of such materials, and economies of shipment.

Abstract: Abstract of the Disclosure nitric acid solution of spent fuel is primarily clarified by a centrifugal clarifier so as to separate insoluble fission particles each having a size of 1.04 µm or more from the solution.  The primary clarified liquid is again clarified by a pulse filter device so as to remove small particles each having a size between 0.8 µm and 1.04 µm.  The filter removes particles having a size smaller than a critical particle size of the centrifugal clarifier.  Therefore, the centrifugal clarifier removes most of the fission product particles, and the filter device removes only the small fission particles.  The replacement frequency of the filter is decreased, and the small particles are removed to obtain a high-quality clarified liquid.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of bonding together two bodies of the same or different metals at least one of which forms an oxidized coating thereon so readily as to be inherently incapable of being fusion bonded to the other body comprises creating two composite bodies by coating the bodies with metallic layers which are capable of being bonded together by the application of pressure at an elevated temperature lower than the melting point of either body.  Each layer is applied to its associate body by a process in which: 1)   the oxidized coating on each body is physically broken up and at the same time 2)   a new metal surface of increased superficial area is formed on the body while it is in intimate contact with its associated layer to prevent the ingress of air therebetween and the oxidation of the new metal surface so that 3)   the body and its associated layer become bonded together in metal to metal contact and the layer diffuses into the body over substantially the whole of the increased area.         The composite bodies are thereby bonded together with at least predetermined parts of their layers in direct metal to metal contact with one another by a process which does not increase the surface area and is selected from diffusion bonding and transient liquid phase bonding whereby the layers diffuse into one another and further diffuse into the bodies with any excess metal from the layers being expelled from between the predetermined parts until a discrete identity of the layers has been lost and the bodies are effectively bonded directly together.

Abstract: 19                  50,452 ABSTRACT OF THE DISCLOSURE A vacuum contactor having a compact DC electro-magnet with an improved force watts ratio.  The DC elec-tromagnet consisting of a dual pickup coil and holding coil winding assembly and a solid U-shaped core having removable legs secured to a base with an adhesive backed aluminum shim positioned intermediate the legs and base, the ampere turns of the pickup coil being approximately 7.5 times those of the holding coil with the legs of the core being approximately 1/3 the length of those  in a conventional  DC  electromagnet  having  substantially the same force watts ratio.  The  shorter  legs  of the  core reduce  magnetic  losses  and  provide  increased  magnetic coupling with the moving armature of the contactor closing mechanism.  This  allows the  smaller magnet to  exert  a greater force upon the armature  during closing of the vacuum interrupter.  With decreased magnetic losses, the size of the windings can be reduced, facilitating removal of  the  heat  generated  therein  and producing a  small, efficient magnet.

Abstract: ABSTRACT : Radiation-sensitive semiconductor device.     The capacitance of a radiation-sensitive diode can be considerably reduced by giving it the form of a pn junction (7) between a first semiconductor region (4) and a layer-shaped semiconductor zone (5,6), which in operation is fully depleted. The speed of such a diode is favourably influenced by the choice or the shape of the geometry of the layer-shaped zone (5,6). When the latter is formed with parts (6) decreasing in width of thickness, an electric field is produced in these parts which accelerates the transport of minority charge carriers to a central contact (13).

One group of the function setting inputs are preferably address designating signals which are utilized for determine ing the interface.  The other group of the function setting inputs determines various additional functions such as, for example, enabling/disabling of fail-safe function and automatic transmission function.  Selection with the aid of the matrix allows selection of a large number of functions with a small number of input signals. Utilization of the address signals to this end allows the number of terminal pins to be decreased to a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE        A conveyor has successive mutually spaced driven rollers on which hot rolled steel rod is transported in the form of overlapping offset rings.  The rings are rapidly air cooled by first nozzles which direct first jets of cooling air upwardly to impinge against and to flow around the conveyor rollers  and by second nozzles which direct second jets of cooling air upwardly between the rollers.          The first and and second jets of cooling air produce respective first and second velocity profiles  each having an average velocity.  The arrangement of the first and second nozzles in relation to each other and to the conveyor rollers is such that the velocity profiles of tie first and second jets are superimposed one over the other to produce a broader combined velocity profile having an average velocity greater than that of either the first or second velocity profiles.
