Patent DE-3039422-A1 (DE)
Title: Self-aligning bearing for electric motor shaft - has plastics shell on outer race, with protruding, annular bead fitting in cylindrical housing radially
Inventor: BRANDENSTEIN MANFRED
IPC: F16C19/54
Filed: 1980-10-18
Abstract: The bearing is in two parts and has an outer race (1) which is bonded to an outer shell (2) of soft elastomeric material. The central area (3) of the periphery of this shell carries a radial annular bead with conical face (4) in one direction. A step in the other direction runs into a short axial length (7) of constant diameter. When this outer race assembly is fitted into a cylindrical bore (5) of a bearing housing (6), the outer shell is compressed, with a locally higher compression in the region of the bead (3). This allows the outer race a limited angular movement in any radial plane so that the bearing is self-aligning. At the same time the radial pressure between the outer shell and housing creates sufficient friction to prevent any axial movement of the bearing.

Piston movement is so co-ordinated that at any instant combustion- and induction-, and compression and exhaust-, chambers are diametrically opposed and travel around the periphery.
Patent DE-3102109-A1 (DE)
Title: Periodically acting brake system for vehicles
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: B60T8/32
Filed: 1981-01-15
Abstract: In the braking of vehicles it is known that the wheels lock when the braking forces exceed the road surface adhesion. Locking wheels mean a reduction of the braking force and loss of the ability to control the vehicle. It is known that this condition can be overcome by "cadence braking", a manoeuvre which assumes great knowledge of the handling characteristics of the vehicle, in which the braking process is periodically relaxed and intensified again. In order to make these braking processes easier for the vehicle driver, the brake system in accordance with the invention has a device, which automatically and periodically relaxes the braking force and intensifies it again. By suitable design of the structural elements a braking characteristic can be achieved, in which under all road surface adhesion conditions the braking forces periodically exceed and fall short of the locking limit of the wheels, thereby maintaining the optimum braking force and control characteristics of the vehicle.

Patent DE-3105346-A1 (DE)
Title: Roller holder
Inventor: WILKE RUDOLF
IPC: A47K10/38
Filed: 1981-02-13
Abstract: A roller holder having a yoke (15) receiving a cylindrical roller (33) with an axial central channel is fastened to a wall (34). The yoke has a straight roller-carrying part (15'') extending parallel to the wall (34). It is guided by way of a right-angled bend (15') to a hinge part (11) to be fastened to a wall and is mounted there via a bearing journal (14), extending in a prolongation of the bend, so as to be pivotable away from the wall about a pivot axis extending parallel to the axis of the roller-carrying part. Moreover, the bearing journal (14) is also pivotable about an axis of rotation extending essentially in the direction of its longitudinal axis (16). In order to prevent the holder from jamming during a pivoting movement about its pivot axis (35) as a result of the dead weight of the article suspended on the roller-carrying part (15''), in each pivoting position about the pivot axis (35) extending parallel to the axis (36) of the roller-carrying part the bearing journal (14) is pivotable about its longitudinal axis (16) out of the position of use into a set-out position counter to a detaining force generated by detention means (19, 21). The roller-carrying part (15'') can thereby be swung away from the wall (34) so far that it extends perpendicularly to the latter. <IMAGE>

IPC: B43L13/08
Filed: 1981-03-31
Abstract: The handle (1) of the drawing head (2), made from plastic, has a cylindrical projection (11) designed integrally therewith. This projection (11) can be connected to the scales via an angle piece, in a manner proof against rotation. The projection (11) is provided on its outer circumference with four T-shaped ribs (19). The projection engages in the hollow cylindrical central part (15) of a grid-type disc made from metal (12). The grid-type disc is fixedly connected to a sector disc. The outer ends of the ribs are provided with webs (23), so that the inner surface (16) of the central part (15) of the grid-type disc bears only on these webs, the friction being reduced. Even when the drawing head is heated, rotation of the handle (1) relative to the grid-type disc (12) is possible as a consequence of the deformable design of the ribs (19). The ribs (19) likewise guarantee play-free running between the projection (11) of the handle and the central part (15) of the grid-type disc (12). The drawing head can be constructed from a few parts. <IMAGE>

Title: Slide valve
Inventor: KROPP WALTER
IPC: F16K11/07
Filed: 1981-05-13
Abstract: Slide valve with a longitudinal bore in the slide, from which narrower transverse bores and further transverse bores further away from the centre of the slide branch off. So that the hydraulic braking and smooth slowing-down are retained and power loss during the acceleration is avoided, two paths for the oil flow are arranged in the piston, where the oil discharge from the consumer is prevented at one of the paths by means of a non-return valve but is possible in the opposite direction, while the second path is closed in a controlled manner at an operating position without a non-return valve and for this purpose each of the narrower transverse bores is arranged in the slide in such a way that, in the neutral position of the slide, it leads into a groove connected to the consumer, and a non-return valve is arranged in the longitudinal bore at least on one side of the same between the entrance of the two transverse bores into the longitudinal bore, which non-return valve in each case opens in the direction of the allocated further transverse bore arranged at the same end of the longitudinal bore.

Title: Process for applying a well-adhering, solderable metal layer to rapidly oxidising metals
Inventor: FINKBEINER LUDWIG ING GRAD
IPC: C23C18/16
Filed: 1981-06-16
Abstract: A process is described with which a well-adhering, solderable metal layer can be applied to rapidly oxidising metals such as titanium, chromium or zirconium or their alloys. To do this, the materials made from the rapidly oxidising metal are freed from their oxide layer in a pickle which contains ions of the solderable metal, e.g. nickel. Preferably, the material is alternately immersed in the abovementioned pickle and in a pickle consisting of concentrated nitric acid or sodium fluoride in sulphuric acid. The metal layers thus produced can be applied e.g. before the soldering of the rapidly oxidising metals, but they can also be used as a substrate for further metal layers which are to be applied electrochemically.

Title: Device for influencing motional processes, in particular a springing and damping device
IPC: F16F6/00
Filed: 1981-07-04
Abstract: The invention relates to a device for influencing motional processes, in particular a springing or damping device. The device comprises an upright (21) and an armature (25). The armature (25) is built up from a column (27) of permanent magnets which plunges into the cup-shaped upright (21), which, for its part, consists of permanent-magnetic annular magnets (22) which are all magnetised in the direction of the wall. The base (24) of the upright (21) is of soft-magnetic design, as is an armature pole shoe (29) which is mounted on the column (27) of permanent magnets, outside the upright (21), and projects beyond the outer edge of the said column to such an extent that it interacts with the top edge of the magnetic sleeve (30) of the upright. The working length of the device depends on the lengths of the column of permanent magnets making up the armature and the length of the magnetic sleeve of the upright. In its embodiment as a tension spring, the magnetisation of the permanent magnetic discs is such that the armature (25) is pulled into the upright sleeve (23). In its embodiment as a damping device, for example as a shock absorber, the upright (21) attempts to drive the armature (25) outwards. <IMAGE>
