Title: Contact link for printed-circuit boards, which are arranged in the same plane, in electrical and electronic apparatuses and installations
Inventor: PAULUKAT FRANK DIPL ING
IPC: H01R31/08
Filed: 1984-12-07
Abstract: The contact link according to the invention consists of a large-area flat metal part on whose edges bent connecting pins are arranged in two rows. These connecting pins are constructed as push-in pins and, at their upper ends, have stop shoulders which ensure an air gap to the printed-circuit boards which are located underneath and are to be connected to one another, so that no additional insulation means are required. Provided in the large-area metal part between the connecting pins are indentations in order that further additional contact links can be arranged in an offset manner. The contact links can additionally have metal tongues, which are bent in an opposing manner to the connecting pins and are suitable for holding wound or plugged-in wire connections. The contact link produces a large-area connection between different printed-circuit boards, resulting in very good electromagnetic compatibility.

Title: Concrete block for garden, park and landscape architecture
Inventor: ROTH REINER
IPC: E02D29/02
Filed: 1985-01-22
Abstract: To produce retaining walls with cast-in-situ concrete cores on cast-in-situ concrete strip footing, for slope stabilisation as a gravity dam with or without a cast-in-situ concrete grout and integrated plant enclosures, as well as for borders and walls, for garden, park and landscape architecture, a concrete block is used which, when lined up, forms the formwork for a cast-in-situ concrete grout due to the corresponding, mirror-image shape at the two ends of the concrete block. The block is formed between these two formwork parts in such a way that the thrust of the slope is diverted according to the principle of the arch via the concrete block to the cast-in-situ concrete cores, which, depending on the static loading, transfer the forces via appropriate reinforcement into a continuous footing, the earth to be held then resting on the strip footing and giving the system its stability.

Title: Load interrupter switch
Inventor: HOEGL VITUS
IPC: H01H71/12
Filed: 1985-07-11
Abstract: A load interrupter switch (2), especially for use in open-air installations and of a three-pole design has in each case two connecting tabs (18, 20) per current path, a switching blade (22) which operates as a switching element, and a high-power fuse link (12). Operation of one of the fuses (12) results in a pulse being passed into a switching box (26) in which a mechanically time-delayed drive mechanism moves a switching shaft (54) in order to disconnect all the poles of the load interrupter switch (2). The mechanical delay of the drive mechanism in the switching box (26) ensures that even fuse links (12) which react slowly will interrupt an overload current before the load interrupter switch (2) is opened, so that reliable switching is ensured without overloading. <IMAGE>

Title: Multi-speed gear hub for bicycles or the like
Inventor: BERGLES EDUARD ING
IPC: B62L5/02
Filed: 1985-08-02
Abstract: The invention relates to a multi-speed gear hub for bicycles or the like with a gear shift in which a planetary gear can be moved into engagement by means of a ratchet system and the shifting of the ratchet by the axial displacement of at least one coaxial component can be controlled via a thrust block in such a way that the axially displaceable component is constructed as a shift ring and is operatively connected to the thrust block and that as a result the driver can be alternately coupled either to an axially securing, coaxial planetary gear carrier or to the associated ring gear which is arranged so as to be axially displaceable counter to spring tensioning. By means of this design, a multi-speed gear hub for more than three speeds and with a back pedalling brake device is obtained. Changing gear is made possible here with a single shift element from one side of the hub axle. The back pedalling brake acts with unchanged braking force regardless of the respective shift position of the hub gear (Fig. 1). <IMAGE>

Title: Thin-film magnetic head for the perpendicular magnetisation of a corresponding recording medium
Inventor: RAITH HERMANN
IPC: G11B5/31
Filed: 1985-12-18
Abstract: The thin-film magnetic head for a recording medium to be magnetised perpendicularly (vertically) has two magnet legs of laminated construction, the magnet poles of which are arranged one behind the other, seen in the (relative) direction of movement of the head, forming a gap of predetermined width. It is intended with this head to be able to perform a read and write function with high efficiency in each case. According to the invention, for this it is provided that the leading magnet leg (9), seen in the direction of movement (v), has at least two magnetic layers (9a, 9b) of different saturation magnetisation (Ms1, Ms2), the magnetic layer (9b) of the comparatively smaller saturation magnetisation (Ms2) bounding the gap and, in the write function, being driven into the saturation by a corresponding write current (I) as far as into the region of the assigned magnet pole (P1), and that the trailing magnet leg (10), the pole face (F2) of which is to be at least as large as the pole face (F1) of the leading magnet leg (9), contains at least one magnetic layer (10a) of comparatively greater saturation magnetisation (Ms3). <IMAGE>
Patent DE-3545657-A1 (DE)
Title: Hydrodynamic retarder
Inventor: BROSIUS KLAUS
IPC: B60T1/08
Filed: 1985-12-21
Abstract: In a hydrodynamic retarder with a rotor blade wheel and a stator blade wheel two working circuits are located, that is an inner core circuit and a ring circuit enclosing this. Both circuits have raked blading with different rake directions. This makes such a retarder suitable for operation in both directions of rotation. The further development according to the invention lies in the fact that the core circuit enclosed by the ring circuit is radially so arranged that the radially outer end cross-sectional area for the fluid passage is equal in size to the radially inner end cross-sectional area. As a result, whilst maintaining a constant cross section along a flow path, even within the blade duct, any jerk due to retardation and acceleration of the flow is prevented, which leads to an increase of the brake power of the retarder.

Title: Device for filling wire-basket trolleys with goods, in particular for retail outlets with conveyor belt systems at the checkout
Inventor: TEUTSCH GERD
IPC: B62B3/18
Filed: 1986-06-27
Abstract: Device for filling wire-basket trolleys with goods, in particular for retail outlets with conveyor belt systems at the checkout. The wire-basket trolley which is moved up to a groove at the end of the conveyor belt system and has an inserted pan which can be moved about an axis of rotation is raised at the front by levers via a rigid connection, as a result of which the pan is also raised until under the groove. The distance between groove and floor of the pan which is now small permits the wire-basket trolley to be filled mechanically by the conveyor belt system. During filling, pan and wire-basket trolley are slowly lowered again by the levers, thus releasing loading space in the upper area until the pan has reached the floor of the wire basket.

Title: Circuit arrangement for testing video amplifiers of television cameras
Inventor: HAIST WALTER DIPL ING
IPC: H04N17/00
Filed: 1986-07-21
Abstract: For testing television cameras with receiving tubes of the Vidicon type, it is known to use, instead of the objective, a wide-band test amplifier with high output impedance, the output of the test amplifier being connected to the input of the video amplifier. Although this makes it possible to test the camera under the actual operating conditions, the exchange of test head and objective is disadvantageous. This disadvantage is avoided by the present invention in that the test amplifier (FET) is built into the camera and the load resistor (R5) of the pick-up tube (AR) can be optionally connected as an output resistor of the test amplifier. The main field of application of the invention pertains to television cameras. <IMAGE>

Title: Bodies of plastic, rubber and/or metal, in particular skittle balls (bowls), and process for the production thereof
Inventor: KLOOS HANS
IPC: A63B37/00
Filed: 1986-12-08
Abstract: It has hitherto not been possible to produce bodies of plastic, rubber and/or metal having wall thicknesses from a specific order of magnitude or relatively large material accumulations by the injection moulding or diecasting process. To be able to use the aforementioned processes even in the case of such large-volume parts, it is proposed that, before the moulding, a honeycomb body (5) also produced by the injection moulding or diecasting process is inserted into the hollow mould (1, 2) determining the external shape of the body, which honeycomb body contacts the mould interior surface at only a few points (9), otherwise having approximately equal spacings to the mould interior surface and open hollow spaces and that then the hollow space system existing between the mould (1, 2) and the honeycomb body (5) is injected full. Special honeycomb bodies for producing skittle balls or bowling balls from plastic are described. The honeycomb body (5), also produced by the injection moulding process, can also be held firmly by means of a movable slide (3) projecting into the mould cavity. <IMAGE>

IPC: H01F27/245
Filed: 1987-01-02
Abstract: The design of the five-limbed core having main limbs with a cooling duct, consisting of oriented magnetic sheet steel, is achieved in such a manner that a sheet-metal segment in the form of an isosceles rectangular triangle is positioned in the T-connection in each layer in such a manner that one of its sides rests on the metal sheet of one half of the main limb and its other side rests on the associated metal sheet of the yoke, and bridges the cooling duct of the main limb in such a manner that its base (hypothenuse) rests on the metal sheet of the other half of the main limb. In comparison with the prior art, a T-connection having reduced magnetisation losses has been achieved by the solution according to the invention, the material used for the purpose having been better utilised.
