Patent DE-3347065-A1 (DE)
Title: Method for the production of forged groundworking tools
IPC: B21K19/00
Filed: 1983-12-24
Abstract: Method for the production of forged groundworking tools provided with at least one forged working edge, in particular groundworking tools for agricultural machines, from a low-alloy forgeable steel alloy. A blank is first of all produced, the blank is heated to a temperature for the forging operation and at least the working edge is forged. This is followed by a hardening step. The blank is heated to a temperature of below 1050 DEG C for the forging operation. The working edge is then forged with a degree of deformation of 20 to 60%, in relation to the cross-section. Hardening is then carried out from this temperature by quenching in oil.

Inventor: BERNER REINHARD
IPC: B63B35/79
Filed: 1984-01-21
Abstract: A device is proposed, the object of which is to make it substantially easier to raise the rig of a surfboard. This device consists of a floatable mast casing 3 of a volume producing buoyancy. The mast casing 3 can be slipped onto the mast 2 of the rig, is adapted on its inside to the mast 2 and extends at least over a substantial part of the mast length. This device holds the mast 2 of the rig lying in the water together with the part of the sail 4 directly adjoining it above the water surface, as a result of which the sail together with the mast can be released from the water substantially more easily than hitherto right at the start of the raising operation. <IMAGE>

Title: Axial piston machine
Inventor: REIMERS ERNST
IPC: F01B3/00
Filed: 1984-05-26
Abstract: An axial piston machine in which pistons arranged in a circle at equal circumferential intervals in a rotatable cylinder drum can be axially moved by means of an inclined axis or a swashplate, the connecting bores or ducts leading to the cylinder bores being connected to a control plate, which has two reniform inlet and outlet apertures (kidneys) lying opposite one another, which are respectively separated from one another by webs arranged in the area of the inner and outer dead centre, the width of the webs sufficing to cover a connecting bore, is to be designed so that housing vibrations are largely prevented and noise phenomena are reduced.

Patent DE-3435066-A1 (DE)
Title: Method and apparatus for the automatic welding together of vehicle axles
IPC: B60B35/16
Filed: 1984-09-25
Abstract: An apparatus (1) (Fig. 3) serves for the automatic welding together of vehicle axle bodies comprising a main body and prepared individual components. The apparatus (1) forms a welding line with work stations (9 to 16) arranged in series adjacent to one another. Arranged in parallel with these work stations is a feed device (17) via which individual stations (9 to 16) can be approached selectively for insertion or removal. The individual welding stations are designed in such a way that it is in each case possible to manage with three-axis continuous-path control systems. In addition, individual stations can carry out different welding operations so that, if one welding station breaks down, another welding station can take on its function if required. Production standstills are thereby avoided. The apparatus (1) is equipped with a guiding and transfer system which matches all the stations and cooperates with clamping holders (24) which are connected in a pre-adjusted position to one axle body (2) at the beginning of production and remain connected to it in this position during all the operations. <IMAGE>

Patent DE-3441577-A1 (DE)
Title: Bolsterless pneumatic suspension bogie for rail vehicles
Inventor: UEBEL LUTZ DIPL ING
IPC: B61F3/12
Filed: 1984-11-14
Abstract: Multi-element rail vehicles for local transport are usually connected by a central bogie on which successive wagon bodies 1 and 2 are supported (Figure 1). According to the invention, this support is effected via air spring bellows 3, 4 which are arranged at the point of intersection of the cross-members 5, 6 with a longitudinal member 14. The longitudinal member 14 which is situated in the central longitudinal plane transmits the pulling forces and impact forces from one wagon body to the other. These forces are applied at both ends via in each case one impact-absorbing element 16 which is connected via a pin 15 to the wagon body 1 (Figure 1), the impact-absorbing element 16 being equipped with a spring tube 20 for the purpose of damping, which tube brings about the application of the forces to the cross-member 5 and the longitudinal member 14. For the purpose of lateral guidance of the wagon body 1, the pin 15 is mounted in the housing 18 of the impact-absorbing element 16 and the housing 18 is guided in a vertically sliding fashion in a U-shaped projection 19 of the cross-member 5. The connection of the wagon body 2 which can be seen in Figure 1 is effected in a symmetrical manner. By virtue of the integration of the longitudinal member 14 into the frame of the bogie, space and weight are saved and the axle spacings are also reduced.

Title: Testing device for optically readable information carriers in disk form
Inventor: ULLRICH JENS
IPC: G01N21/21
Filed: 1985-04-30
Abstract: Optically readable information carriers in disk form, for example video disks, digital audio or data storage disks, are generally produced by the transfer moulding process. In this case, during the course of their production, defects can occur in the information area during the successive operating steps due to material inclusions, small bubbles and surface damage, which cause falsifications of the information content even when of the order of magnitude of just a few micrometers. Even birefringent characteristics of the substrate disk can result in such informational falsifications. To test for such defects, a compact testing device is specified, which device operates with polarisation filters and in which the information carrier (5) to be tested is secured on a raised rest (3) in a peg arrangement (4), a covering is created in the form of a hinge-opening lid part (6) and a filter plate (11) which can be swung out from the lid part, and in which the bottom (8) of the lid part represents a first polarisation filter, to which a similar polarisation filter is assigned in the form of the filter plate. <IMAGE>
