Patent DE-3304458-A1 (DE)
Title: Closed self-resetting rotary joint
IPC: E05D11/04
Filed: 1983-02-09
Abstract: The self-resetting rotary joint is suitable especially for doors and has a subdivided ball, the two halves of which are each connected to a hinge tab and have a centrally arranged pin passing through them. The pin is at an angle to the vertical and passes vertically through the parting faces of the two ball halves, so that these parting faces are at an angle to the horizontal. Arranged in the parting face are circular grooves, in which balls are inserted, so that a pivoting of the upper ball half together with the associated connecting part and the hinge tab arranged on it allows an opening of the door which, after the opening force has ended, returns to its closed position automatically. During the opening and closing, the door maintains its vertical position relative to the ground. <IMAGE>

Title: Continuously variable cone sheave contact transmission
Inventor: BARTHOLOMAEUS REINER
IPC: F16H61/662
Filed: 1983-03-24
Abstract: The transmission ratio of a cone sheave contact transmission with pressure cylinders on the drive and output side is varied by means of a control valve which increases the pressure in one pressure cylinder and at the same time reduces the pressure in the other pressure cylinder. A basic pressure valve connected into the return of the control valve sets a certain basic pressure in the system, below which the pressure may not fall, so that the traction mechanism strand for the torque transmission is held under a certain pretension. According to the invention a control valve of simplified construction is provided and the strokes of both pressure cylinders for the drive and output pair of cone sheaves are synchronised hydraulically. The basic pressure valve also permits ease of locking when the transmission ratio is not to be varied and permits a variation of the basic pressure as a function of the transmitted torque. <IMAGE>

Inventor: TAUTZENBERGER PETER DIPL ING D
IPC: H01H37/46
Filed: 1983-05-28
Abstract: A shaped part made of a composite material having shape memory properties is intended to be assembled in such a way that various changes in shape, including complex changes, take place in dependence on the temperature. This is achieved by providing that the shaped part has several sections which have shape memory properties and which are coupled together with one another in such a way that independent results of the shape memory effect cause temperature-specific changes in the shape of the shaped part, in the course of which the shaped part assumes the same number of permanent and/or reversible shapes as the number of sections having shape memory properties.

Title: Luggage rack for two-wheeled vehicles
Inventor: BELKA HEINRICH
IPC: B62J7/04
Filed: 1983-12-03
Abstract: A luggage rack for two-wheeled vehicles contains a frame which forms the support surface of the rack and from which in each case a pair of supporting legs extends downwards on each side, the legs of which, which are attached to the frame in an articulated fashion if appropriate, and extend towards one another in a V shape, are bent over at their free ends in such a way that they are aligned approximately parallel to one another lying at a small distance one next to the other. The free ends of the legs of each pair of legs are adjustably attached to an extension piece of the vehicle frame by means of a clamp component which has a bore for an attachment screw which passes between the two ends of the legs and an attachment screw which passes through a bore of the extension piece. In order to provide a large adjustment range of the two legs of each pair of supporting legs without adversely affecting the transverse stability of these supporting legs, so that adaptation to the conditions of different two-wheeled vehicles is possible without changes to the luggage rack itself, the clamp component has two continuous receiving bores which extend in parallel to one another for the two associated cylindrical ends of the legs. At least one clamp element which interacts with the plugged-in ends of the legs is assigned to the receiving bores and can be tightened by means of a clamp screw in order to fix the ends of the legs.

Patent DE-3404755-A1 (DE)
Inventor: SKUTHAN ERICH
IPC: B25C5/16
Filed: 1984-02-10
Abstract: A driving device for securing fasteners (7) such as nails, staples, etc., which are stored in a magazine (6) to be supplied to an ejection channel (5) provided with an opening (8) closed by a spring biased nose plate (9) elastically held by a spring (14) against the opening (8) of the ejection channel (5) in the nose portion (4) on the side opposite the magazine (6). When jamming occurs between a driving plunger (2) and fastener (7), the nose plate (9) lifts itself against the bias of the spring, whereby jamming is frequently avoided automatically. If jamming occurs nevertheless, the nose plate (9) may be completely removed from the opening (8) of the ejection channel (5) so that the jamming may easily be cleared. Potential jamming situations are often avoided since the nose plate (9) may deflect to partially open the ejection channel (5).

Title: Local communications system with a star-type network and optical channels
Inventor: KREUTZER HEINRICH W DIPL ING
IPC: H04Q3/52
Filed: 1984-05-18
Abstract: Local communications systems exist for different services. In PBX systems, >>telephony<< is of prime concern. Distributed processors communicate via data buses. The problem of implementing or including broadband services is still essentially unresolved. A local communications system according to the invention offers enough flexibility to meet most of the sector-specific requirements for individual services but nevertheless to develop the integration of services. Optical communications technology is used for transmission and switching. The components located between the subscriber stations are essentially passive. The network is designed with a star structure. Narrowband and mediumband traffic is handled in a fully synchronous time division multiplex system with random access and high-speed circuit switching. In an intrinsically separate transportation of broadband services, their signalling is carried out as for narrowband services. Unauthorised access to time slots can be prevented through additional measures. <IMAGE>

In order that these articulated shafts, despite the short distance between the distribution drive and the wheel hub, do not become so short that either the angle or excursion is very limited, or that the articulation must be stressed unfavorably, and to permit larger spring paths for the wheels, the articulations were integrated into the housings of the distribution and/or wheel hub drives to the extent that the center of the articulation comes to lie immediately at or even behind the intersection of the articulated shaft with the drive train and below the output bearing. The latter receives therto a specially large diameter and short construction length.

Patent DE-3502234-A1 (DE)
Inventor: WILHELMI JUERGEN
IPC: E04B1/26
Filed: 1985-01-24
Abstract: A metal fitting for forming an end connection of a wooden beam, such as a roof beam or purlin, to a supporting structure, which may also be a wooden beam, such as a main beam or truss, characterized by a web having opposite bearing surfaces, one bearing surface engaging a surface of the supporting structure and the other surface engaging the end of the beam. The one surface has an arrangement, such as a supporting flange extending perpendicular thereto, for mounting the fitting on the support structure. To mount the beam, the fitting has at least one leg extending perpendicular from the other bearing surface having a constant thickness and being provided with a groove-like attenuation to separate the leg into a supporting portion and a free end portion, which free end portion has openings for receiving fastening elements. The attenuation prevents the transfer of forces extending parallel to the web being applied to the free end portion from being transmitted to the web, but allows tensile forces to be transferred to the web of the fitting.
