Title: Unit for the delivery of fuel from a tank to the internal combustion engine, especially of a motor vehicle
Inventor: KLEPPNER STEPHAN DIPL ING
IPC: F04C15/00
Filed: 1986-11-13
Abstract: The fuel delivery unit comprises an electrical drive motor, energised by a permanent magnet, and a displacement pump (for example a G-rotor or roller cell pump) operatively connected to the said engine, the rotationally driven delivery element of which pump located close to the motor armature viewed in the direction of the engine's axis of rotation, is located in a pump chamber, which is defined by two walls arranged at a distance from one another transversely to the axis of rotation. The chamber wall situated between the motor armature and the delivery element has a pressure orifice, which opens into a space accommodating the electric motor, enclosed by a housing and belonging to the delivery line. An especially simple construction of the fuel delivery unit is achieved in that the wall provided with the pressure orifice is formed on a plate, freely movable in an axial direction between stops, and in that both the delivery element of the pump and the plate are made from an antimagnetic material. <IMAGE>

Title: Tube connection and device for producing the same
Inventor: KUSCH DIETER
IPC: F16B7/00
Filed: 1987-08-29
Abstract: Tubes which intersect have, up until now, predominantly been produced such that the tube casings are welded to one another at the point of intersection. As a result of the accumulation of material of the wide weld seam which is necessary in order to achieve the necessary strength of the weld connection, weld connections of this type have an unattractive appearance. The tube connection is configured such that it is distinguished by a high strength, a visually pleasing form and a simple and inexpensive production. The tube connection exhibits an annular intermediate piece 4 which rests, by means of its borders 5, 6, in a positively locking manner on the casing surfaces 7, 8 of the tubes 2, 3 which are to be connected, spaces said tubes apart and is soldered or welded to the tubes. The intermediate piece 4 is produced by means of a pressing tool, whose upper part and lower part each exhibit a cylindrical shaped piece, whose diameter corresponds to the external diameter of the tubes which are to be connected, the two shaped pieces being rotated with respect to one another through the angle of intersection of the two tubes which are to be connected. The tube connection is preferably provided for the production of tables and pieces of seating furniture. <IMAGE>

Patent DE-3807512-A1 (DE)
Inventor: BUSSE KARL-HERMANN DIPL ING
IPC: B22D19/08
Filed: 1988-03-08
Abstract: In order to produce a wear-resistant hard-metal material composite in a continuous fashion by centrifugal casting (vertical and horizontal centrifugal casting), solid, pulverulent and/or granular, synthetic, metallic and/or non-metallic hard materials are from time to time during the casting process injected into the metal stream flowing into the mould, by means of a conveying device and using an inert conveying gas. As a result of the associated simplicity of parameter control, the armouring of large, rotationally symmetrical components, such as rolls and rollers, against wear using solid synthetic hard materials by casting is for the first time possible in an economical and reproducible manner. By agglomeration of hard materials and metals of different densities with the aid of organic and inorganic binders, it is possible to use even very hard low-density borides, oxides and carbides which dissolve very slowly in molten metals for armouring the outer surface of the casting, namely the surface facing the mould wall. <IMAGE>

Abstract: Deflection circuit for television tube. In a deflection circuit for a television tube, which comprises a horizontal generator (16) and a vertical generator (2) for controlling a horizontal (17) and vertical deflection coil (1), respectively, the horizontal generator (16) is intended to generate a symmetric output current. According to the invention, the vertical deflection coil (1) is supplied both with the output current (iv) of the vertical generator (2) and with a correction current (ik) obtained from the output current (ih) of the horizontal generator (16). In this arrangement, the correction current (ik) is at times directed oppositely to the output current (iv). A symmetric deflection requires a lower electrical power than a sawtooth deflection and is appropriate, particularly in the case of large, high-intensity picture tubes. The circuit according to the invention achieves a uniform line spacing with symmetric deflection.
