Abstract: A scandate dispenser cathode having a cathode body (4) arranged on a cathode support (3), a cathode coating (5, 6) comprising a layer system (6) consisting of one or more alternating layers of rhenium or a rhenium alloy (61) and of scandium oxide or a scandium alloy (62), and an activation acceleration layer system (5) arranged between the cathode body (4) and the layer system (6), said activation acceleration layer system comprising at least one release layer (52) comprising alkaline earth metal oxide, preferably barium oxide, and an activator layer system (51) comprising a barrier material with greater oxidation resistance than the material of the cathode body and an activator material for reducing the alkaline earth metal oxide, preferably barium oxide.

Abstract: A line combination includes at least two parallel flexible lines, which connect a connector fixed in place locally or on a machine with a moveable machine part, and can be displaced axially relative to one another in the combination. The term “lines” covers cables and hoses of all types. Connecting elements are attached or molded onto the lines, which produce the connection between the lines and permit only axial relative movements between adjacent lines.

Abstract: An improved shoe, promoting a heel-to-toe motion of a foot, comprising an outsole and an upper part. The outsole has a contraction extending to a first area where a back of the foot is located. The upper part has a heel guide, including one of a heelplate and a flexible heel brace, which are arranged in a second area where the heel of the foot is located, such that an Achilles tendon of the foot is free.

Abstract: An electric discharge tube or discharge lamp comprising a scandate dispenser cathode which is composed of a cathode body and a coating having an emissive surface, said cathode body including a matrix of at least one refractory metal and/or a refractory alloy and a barium compound which is in contact with the matrix material to supply barium to the emissive surface by means of a chemical reaction with said matrix material, and the coating containing one or more multilayers which may include a bottom layer of tungsten and/or a tungsten alloy, an intermediate layer of rhenium and/or a rhenium alloy and a top layer of scandium oxide, a mixture of scandium oxide and rare-earth metal oxides, a scandate and/or a scandium alloy, is characterized by a long service life and a high emission-current density.

Abstract: An electromotor including a stator (32) having a central receiving region for a rotor (23), at least two, projecting into the rotor-receiving region, stator pole pairs (18, 19, 20, 21), an insulation element (1, 2) provided at each end side of the stator (32), a stator winding (16, 17) surrounding a stator pole pair (18, 19, 20, 21) and a portion of a respective insulation element (1, 2), a permanent magnet (14, 15) between a pair of adjacent stator poles (18, 19, 20, 21), and dielectric support elements (7, 8) cooperating with respective insulation elements (1,2) and arranged along the main axis of the rotor-receiving region of the stator (32) between side surfaces (28, 29, 30, 31) of the stator poles (18, 19, 20, 21), which extend substantially parallel to the main axis of the rotor-receiving region of the stator (32) and to each other, and the stator windings (16, 17), respectively.

Abstract: A cable carrier chain made of pivotally connected pairs of spaced apart, parallel sidebars has crosslinks spanning the pairs of sidebars which are engaged in notches in the edges of the sidebars. The crosslinks are placed in the notches and are longitudinally slid to an engaged position where flanges of the crosslinks are received in undercuts in the notches to secure the crosslinks to the sidebars against vertical relative movement. In the engaged position, bars, bosses or tenons of the sidebars which have laterally facing surfaces are engaged by slots in the crosslinks to prevent lateral movement of the crosslinks relative to the sidebars. A key or a tab is provided to secure the longitudinal position of the crosslinks relative to the corresponding sidebars to prevent retrograde movement of the crosslinks from the engaged position.

Abstract: A self supporting cable carrier in the form of a flexible tube for fully enclosing the cable to protect it from damage as well as to support it. The flexible tube comprises a plurality of segments or links coupled to each other successively and pivotable relative to each other a limited amount. The segments are constructed so that they can etend in a straight line and can pivot from this straight line in one direction but not in the other direction. As a result the carrier can carry the cable along a curve in one direction but a span of tubing extending across a space cannot collapse since the segments cannot pivot in that direction. This arrangement makes the carrier self supporting along such span. The segments are formed of molded plastic with each segment having a pair of bosses extending inwardly from its trailing portion and a pair of complementary openings in its forward portion for receiving the bosses from the adjoining segment to couple the two segments together.

Abstract: A conductor guiding support formed of two chains retained in parallel spaced apart relationship by spacers which support the conductors between the chains. The chains are formed of successive links pivotably coupled to each other with each link being formed of two matching plates. One end portion of each plate is provided with a central hole and arcuate slots spaced about a circle that is concentric to the central hole. The opposite end portion of the plate is offset and is provided with bosses that are in a pattern that corresponds to the pattern of the hole and slots on the other end. Two plates are placed face-to-face to form a link and the portions with the central hole and arcuate slots are in surface contact with each other while the offset portion that present the bosses are spaced from each other. The portion of the succeeding link with the contacting surfaces is placed in this space with the bosses of the offset portion engaging the openings in the surface contacting portions.

Abstract: A suspension of a poorly water-soluble iron (II) containing compound in a liquid which consists substantially of water and is preferably alkaline is oxidized, to form goethite crystals and particles. The crystals and particles are filtered off, washed and dried. From a thermodynamic point of view, "more monoenergetic" particles are obtained than particles manufactured according to conventional production processes, when electrolytic oxidation processes are used, in particular, when the oxidation to goethite occurs entirely or partly by a (preferably periodic) electrolysis process. The electrolysis process may be combined with oxidation by an oxidation agent, preferably an oxidizing gas or gas mixture. Furthermore, it is possible to first oxidize the iron (II) containing compound completely to goethite by an oxidation agent, preferably an oxidizing gas or gas mixture, and to then subject the resulting suspension to an electrolytic oxidation after-treatment which preferably occurs periodically.
