Patent DE-3643259-A1 (DE)
IPC: B32B15/01
Filed: 1986-12-18
Abstract: The core of the work roll consists of an iron alloy, and the shell of the roll consists of an iron alloy having the following constituents in % by weight: C = 2 - 3.5, Cr = 10 - 25, Mo less than 5, Ni less than 2, Mn less than 2 and Si less than 1. These known work rolls have the disadvantage that they cannot be used universally in spite of a comparatively high wear resistance, for example not in the first stands of a finishing step for special sheet grades and of hot-rolled strip lines. To eliminate these disadvantages, the Ni content of the iron alloy of the shell is increased to 4 - 6 % by weight. In other respects, the usual composition of high-chromium rolls is maintained. As a result of this effect on the metal structure matrix, the disadvantageous properties of the known work rolls are eliminated, with unchanged carbide structure. Surface hardnesses between 60 and 100 ShC can be achieved.

Title: Cable sleeve and a method for its production, especially for coaxial connecting joints
Inventor: MARGREITER HANS
IPC: H02G15/113
Filed: 1987-03-23
Abstract: Cable sleeves may consist of two half shells which have an internally conductive housing which is possibly provided externally with a non-conductive protective layer. The separating plane can in this case lie between the half shells in such a manner that each plug connection is also separated into two half-cylindrical shapes. The disadvantage of this is that a permanent joint between the half shells can be produced only at high cost. However, a permanent joint in the region of the plug connections is above all impossible without further technical components which are plugged into or onto the plug connection. In order to overcome the disadvantages, it is provided that at least one and preferably both half-cylindrical shapes (3') which form the tubular plug connection (3) in the assembled state, have a projecting material region section (17) in at least one length region element on at least one longitudinal side (15), which material region section (17) is pressed in a positively locking manner together with the other half-cylindrcial shape (3') or a material region section (17) which is associated therewith and likewise projects in a length region element of the plug connection (3). The cable sleeve is particularly suitable for cable plug joints. <IMAGE>

Title: Method for the electrolytic colouring of anodically generated oxide layers on aluminium and aluminium alloys
Inventor: SLOGSNAT REINHARD
IPC: C25D11/22
Filed: 1987-12-08
Abstract: Method for the electrolytic colouring of anodically generated oxide layers on aluminium and aluminium alloys, which provides for automatic control of the process from the anodic oxidation via the colouring up to densification. Based on the finding that the layer structure of the anodised surface and the number of the pores occupied are responsible for the result of colouring, it was found that the variation of current with time during a direct-current treatment carried out prior to the colouring process provides information on the layer structure. Based on the difference between the maximum and final values of the direct-current treatment, and employing known rules, the effective capacitor current can be calculated. This, together with a constant, forms the basis for the calculation of the initial current and, together with a term taking into account the desired brightness, the calculation of the switching-off current.
