    • A device for feeding fish, especially pet fish, according to which a floating body for floating on the water in an aquarium carries tubular means which are inclined or arranged vertically upwardly from the floating body and are adapted to slideably receive and guide fish food bodies arranged one on top of the other. The lower end of the tubular means is partially open to permit fish access to the respective lowermost body of fish food in the tubular means while preventing a dropping-out of the fish food bodies from the tubular means. The invention also concerns a fish food body which may be ballshaped, may have a spherical head and flat bottom or a conical head and flat bottom or any other shape so as to assure when the fish food bodies are arranged one on top of the other, substantial contact point only of the lower fish food body with the next higher fish food body.
    • 一种用于饲养鱼类,特别是宠物鱼的装置,用于漂浮在水族箱中的水的浮体携带管状装置,其从浮体垂直向上倾斜或布置,并且适于可滑动地接收和引导排列的鱼食物质 一个在另一个之上。 管状装置的下端部分地打开,以允许鱼进入管状装置中相应的最下面的鱼食体,同时防止鱼食体从管状装置中脱落。 本发明还涉及一种可以是球形的鱼食体,可以具有球形头部和扁平底部,或者具有圆锥形头部和扁平底部或任何其它形状,以便确保鱼食主体何时一个放置在另一个之上, 实质的接触点只有较低的鱼类食物与下一个较高的鱼类食物体。

    • An apparatus for the production of tubular bodies, in particular for packaging tubes, from a foil strip (48) which comprises weldable plastic material and the longitudinal edges of which are thermally joined together has a shaping belt (46) which co-operates with shaping rollers (59, 60) and which shapes the foil strip (48) around a mandrel (45) to provide a tubular body, a lower driven transportation belt (20) which runs in the mandrel (45) and an upper driven transportation belt (33), the longitudinal edges of the foil strip (48) being accommodated in mutually overlapping relationship between the transportation belts. The upper transportation belt (20) is in the form of an endless belt which passes beneath a heating means, a pressing means and a cooling means and the heating means is in the form of an inductively operative high frequency heating means. In a process which can be carried out with that apparatus, the foil strip (48) is formed into a tube with an overlap formed from the edges of the foil, for the purposes of forming a welded seam in its longitudinal direction, and the overlap is introduced with its outer and inner sides of the tube into a belt gap (70) which is formed from the two transportation belts (20, 33) which are driven and circulate endlessly in parallel relationship, is melted therein by the transportation belts (20, 33) at least until phases which are capable of flow are formed, is pressed with preliminary hardening of the phases which are capable of flow, and is then cooled under the application of pressure.
    • 一种用于从包括可焊接塑料材料并且其纵向边缘热连接在一起的箔条(48)制造管状体,特别是用于包装管的装置具有与成形(46)配合的成形带(46) 辊(59,60),并且将箔条(48)围绕心轴(45)成形以提供管状体,在心轴(45)中延伸的下驱动输送带(20)和上驱动输送带 如图33所示,箔条(48)的纵向边缘在传送带之间以相互重叠的关系容纳。 上部输送带(20)为通过加热装置,压制装置和冷却装置下方的环形带的形式,并且加热装置是感应操作的高频加热装置的形式。 在可以用该装置进行的过程中,箔条(48)形成为具有由箔的边缘形成的重叠的管,用于在其纵向方向上形成焊缝,并且重叠 被引入其管的外侧和内侧形成由两个传送带(20,33)形成的带间隙(70),两个传送带(20,33)以平行的关系无限循环地被传送带(20)熔化 ,33)至少直到形成有流动相为止,在能够流动的相的预硬化的状态下进行加压,然后在施加压力的状态下进行冷却。

    • The air supply system for feeding air to a firebox within a building comprises a fresh air intake box (3) in the outside building wall (19) and, in the immediate vicinity of the firebox, a distributor box (7), connected with several pipes (5a, 5b, 5c, 5d). The fresh air intake box (3) has an extensible tube (25) for adaptation to varying wall thicknesses of the outside building wall (19). The prefabricated parts can be readily installed on the building site. By the use of several pipes (5a, 5b, 5c, 5d), the individual pipe cross section can be kept at a small value so that no static impairment of the building ceiling (11), wherein the pipes (5a, 5b, 5c, 5d) are extended, occurs. Advantageously, a fan can be installed in the extensible and readily removable tube (25) in order to increase the flow velocity of the fresh air; servicing of the fan is possible without any problems.
    • 用于将空气供给建筑物内的火炉的空气供应系统包括在外部建筑物壁(19)内的新鲜空气吸入箱(3),并且在火箱附近,分配箱(7)与多个 管(5a,5b,5c,5d)。 新鲜空气吸入箱(3)具有用于适应外部建筑物墙壁(19)的不同壁厚的可伸长管(25)。 预制部件可以方便地安装在建筑工地上。 通过使用多个管道(5a,5b,5c,5d),可以将单个管道横截面保持在较小的值,使得建筑物天花板(11)没有静电损伤,其中管道(5a,5b,5c,5c) ,5d)延长,发生。 有利地,风扇可以安装在可延伸且易于拆卸的管(25)中,以便增加新鲜空气的流速; 对风扇进行维修是没有任何问题的。
