摘要： The invention relates to a drive device for a stop barrier or a stop or closure device with a drive unit having a drive motor (17) to which at least one single-stage step-down gear, worm gear and/or spur gear with an articulation to a pivoting crank (38) is connected, said crank being mounted on a primary shaft (46) pivoting preferably around a horizontal axis at bearing points on both sides. The shaft is provided with a fixing device (40) for the tree of the barrier(41) or barrier or closure element which can generally pivot at an angle of approximately 90 DEG in addition to abutments for the compensation springs (48) which act upon their spring crank. The device is also provided with a single-part, single-piece drive casing (G) with open, flat securing flange strips (2) on all sides and a receiving flange (14) to secure the drive motor (17) which can be dismantled and removed. The motor shaft (36) of the drive motor is introduced into a gearbox (9) which can be closed by a lid (10) and which contains a step-down gear. An output crank (31) is fastened to the gear output shaft (30) and is hingedly connected to the pivoting crank (38) of the drive shaft (46) by means of a swivelling arm (37). The pivoting crank (38) is mounted on both sides on bearing blocks (6) which are formed on the single-piece drive casing (G) and protrudes on one side at least in the area of the bearing point in addition to being provided with a fixing device (40) for the stop or closing member or tree of the barrier (41).

摘要： An electric cable connection for a single or multi-core power and control cable, in which the electrically insulating and sealing coating consists of a cast resin or shrink sleeve (12, 9) and in which the cores (8) in the region of the connector (5) are surrounded by a dimensionally stable coating (2), covered in turn by an outer sleeve covering the core insulation (1) and in which, besides the electrically insulating and damp-proofing protection, there is over each electric core connection, and electrically insulating, damp-repellent, high-temperature and thus fire-resistant moulding (2) remaining dimensionally stable under the action of heat as a casing for each individual core connection (8, 5) permanently spaced apart by heat-resistant spacers, where the dimensionally stable moulding (2) advantageously consists of a fireproof ceramic or a high-temperature-resistant quartz glass or quartz substance.

摘要： A casing pipe with coupling sleeves at one or both ends is used for coupling other casing pipes into a line of casing pipes. The sleeve and peg coupling parts, that are designed as overlapping, interlocking flanges, have radial bores distributed around their circumference and into which coupling members mounted therein with spherical sections (1) are detachably inserted. The spherical sections (1) are flattened on both sides (4, 5) and are mounted in spherical concave bearing surfaces (18) of the inner peg coupling part (16) and in spherical concave counter-bearing surfaces (17) of threaded locking rings (9) screwed into threaded bores (19) of the outer flanges (15).

摘要： A work bench, in particular for welding and structural steel work, has a frame that consists of at least four legs (9) and at least two traverses (10) and two longitudinal flanges (14, 20). At least one first longitudinal flange is fixed to the traverses and has an upwards open T-groove (16) and the second longitudinal flange with at least one upwardly open T-groove (16) is slidingly linked to the traverses so that it may be moved away and towards the first longitudinal flange. The work bench further has at least one guide bar (24) with a prism-shaped cross-section fixed to the frame or to one of the longitudinal flanges that extends parallel to one of the longitudinal flanges. At least one support (30) provided with fastening and clamping elements for holding tools, stops or similar accessories that may or not be motor driven is guided in the longitudinal direction on the guide bar (24). Each longitudinal flange (14, 20) consists of a sectional steel beam that lies on and is secured to the traverses or that is guided in parallel transversely to the traverses. The bearing surface of the work bench may if required be laterally expanded in all directions thanks to retractable parts mounted on the longitudinal flanges and/or detachably set on the frame.

摘要： Proposed is a device for teaching music theory, with a flat, one part or multi-part board made of wood, carboard, plastic or a similar substantially rigid material with a work surface having non-detachable and easily recognizable note systems. The work surface can be written or printed on and covered with a layer of adhesive felt or a magnetic sheet, or a sheet which is adherent in some other comparable way, on which light moulded elements in the shape of any of the notes and other symbols used in the typesetting of music can be easily placed and removed again by hand. The backs of the moulded elements are fitted with hook-and-loop or magnetic, or some other comparable adherent means. The notes and the symbols are made of metal, plastic, wood, rubber or a similar substantially rigid or readily plastically formable material and their surfaces has coloured coatings, or they are made of materials of different colours.
