Abstract: A grid with coolant deflecting channels for used in nuclear fuel assemblies is disclosed. In the grid, two sets of intersecting grid strips are arranged in sets at right angles to each other prior to being encircled by four perimeter strips, thus forming a plurality of four-walled cells individually placing and supporting an elongated fuel rod therein. Each of the grid strips is made up of two narrow sheets which are deformed at a plurality of regularly spaced portions to provide nozzle-type coolant deflecting channels. The channels individually have an upright Y-shaped or reversed Y-shaped configuration capable of so deflecting coolant as to mix low temperature coolant with high temperature coolant. The channels thus form a uniform temperature distribution within a fuel assembly. The channels are so inclined with respect to the axes of the fuel rods as to form wide and linear positioning springs at middle portions thereof.

The narrow side projects as a wall section out of a front wall of two tall case shells which are made mainly of light weight metal and are hinged together. The narrow side features connecting elements to secure a briefcase which, when joined to the case, makes the whole into a rectangular parallelpiped.

Abstract: A collar for protecting the iron spade of an anode rod for a carbon block that serves as an anode in the electrolytic production of aluminum comprises a plurality of shaped carbon blocks each with two close-fitting, abutting end faces and recesses which jointly correspond in cross-section to that of the anode spade or pin and surround the anode spade or pin projecting out of the anode block; the base areas of the said carbon collar blocks form a plane which is in contact with the carbon anode. The shaped carbon blocks are manufactured out of 60-90 wt % carbonaceous solids and 10-40 wt % bitumen binder. Because of their low pore volume the protective collars exhibit a low absorption capacity for sodium and a favorable combustion behavior during the electrolytic process.

Abstract: A method and apparatus for injection blow molding hollow plastic articles characterized by a rapid and efficient operating cycle. The injection mold includes a mold cavity and the blow mold is located adjacent the mold cavity in side-by-side relationship. The parison is injection molded into the mold cavity onto a core. The parison on the core is separated from the mold cavity by moving the parison on the core axially in a straight path away from the mold cavity, followed by movement in a substantially arcuate path into axial alignment with the blow mold, followed by axial movement in a straight path into said blow mold.

Abstract: The surface of a material is inspected for defects by visual examination of a television picture of the surface produced by at least one camera focused on the material and transmitting an image to a screen in the form of a video signal. The connection between screen and camera is made only when a defect is detected on the surface of the material. The video signal is delimited by an upper and a lower signal level which, if exceeded, results in a trigger signal being activated. In addition a trigger mechanism and an image storage facility are provided between the screen and the camera. Appearing on the screen are only pictures of surface areas showing defects; areas without defects are not displayed on the screen.

Abstract: A metal composition, particularly magnesium or a magnesium alloy is activated for hydrogen storage by a plurality of activation cycles each comprising a step of hydriding the metal composition followed by a dehydriding step; in this way the metal composition is activated for reaction with hydrogen for hydrogen storage, more efficiently and in less time than with prior techniques.

Abstract: A portable apparatus for imparting continuous passive motion to a human joint. A support is provided for harnessing to parts of the body at one side of the joint and conveyor means movable relative to the support is provided for connection to a part at the other side of the joint, so that the latter forms a link which is flexed as the conveyor means moves back and forth relative to the support. Drive means insures that a substantially continuous slow rhythmic reciprocating movement is applied to the joint.

Abstract: Pretreatment of aluminum strip or foil for lacquering, adhesive coating or laminating processes involves heavy metal compounds which are considered undesirable for many packaging purposes, in particular for foodstuff packaging. These disadvantages are avoided if the strip or foil is pretreated in an electrolyte by subjecting it to a three phase alternating current of which one phase is rectified and the side of the strip or foil to be treated is made to pass in sequence three electrodes of which at least one is connected to the rectified phase while the others are connected to the other phase of the alternating current. Such a pretreatment has the advantage over an alternating current treatment that the oxide layers offer high strength of adhesion and the treatment can be performed faster.

Abstract: A method and apparatus for removing oil particles and condensate from a stream of compressed air used in the production of snow by snow-making equipment wherein the condensate is first crystallized thus allowing the oil particles to adhere thereto and thereafter the crystallized condensate and oil particles are heated in a holding zone to form a liquid which is separated from the stream of compressed air and drained therefrom.

The filter medium is made up of at least two effective filter layers such that a relatively thick layer of large pore diameter lies on a relatively thin layer of small pore diameter. This arrangement aims at attaining the maximum possible wetting of the interior of the filter medium.

Abstract: 0.05 to 0.2% vanadium and manganese in a concentration equal to 1/4 to 2/3 of the iron concentration are added to an aluminum wrought alloy containing 0.3-1.0% Mg, 0.3-1.2% Si, 0.1-0.5% Fe and up to 0.4% Cu. This alloy is employed mainly for the manufacture of extruded products.

Abstract: The device permits controlled batch feeding from a silo with at least one outlet opening and is particularly suitable for supplying alumina from a day's storage silo to the break in the crust on a fused salt electrolytic cell for producing aluminum. Flanged on to the silo outlet is a feed pipe running at an angle steeper than 45.degree. and joining up to the upper half of a containment pipe, likewise inclined steeper than 45.degree.. This containment pipe features at the bottom a compressed air supply line, at the top a receiving or braking chamber and connecting up to that a discharge pipe. By briefly opening the control valve at regular intervals, compressed air is forced into the containment pipe and the plug of particulate material lying there ejected into the receiving or braking chamber.
