Patent DE-4305614-A1 (DE)
Inventor: ROTHER HANS-JUERGEN
IPC: B62D47/02
Filed: 1993-02-24
Abstract: The invention relates to a hinge for the articulated connection of vehicle sections (1 and 2) of an articulated rail vehicle with the aid of a roller bearing (3) which is held on a support carrier (2a) which projects beyond the end of one of the vehicle sections (2) and interacts in an articulated fashion with a support carrier (1a) which projects beyond the end of another vehicle section (1) and permits horizontal and vertical deflection movements of the vehicle sections (1 and 2) with respect to one another. The objective of the invention is to construct the hinge in such a way that the roller bearing is relieved of wear-promoting stresses and larger horizontal bending angles can be realised between the connected vehicle sections. This objective is achieved in that the support carrier (2a) of the second vehicle section 2 is secured to the inner ring (3a) of the roller bearing (3) by means of an elastomer joint (4), which roller bearing (3) has neither radial nor axial play at least in the installation state. <IMAGE>

Patent DE-4317934-A1 (DE)
Title: Pedal-pulling device
Inventor: SCHLEICH WOLFGANG
IPC: A62B3/00
Filed: 1993-05-31
Abstract: People involved in accidents in motor vehicles often have their legs and feet trapped by the pedals. The conventional rescue tool devices, such as hydraulic rescue tools, cutting implement and spreader are only to a limited extent suitable to release trapped feet/legs. The mechanical pedal-pulling device frees trapped lower extremities more simply and rapidly. Using a 10 mm twist drill on a battery-operated drilling machine a hole is drilled through the mudguard into the leg room of the vehicle. From outside the guide tube (1), which is fastened on the plastic plate (7), is pushed through the hole. The steel cable (2) with the clamping part (3) is placed around the wedged pedal and the clamping part (3) is hooked into the perforated plate (4) in order to form a loop (5). From the leg room the steel cable (2) is passed through the guide tube (1) and introduced (9) into the shaft (8) of the hand ratchet (6). By operating the hand ratchet (6) the cable (2) is wound around the ratchet shaft (8). The resulting shortening of the cable causes the pedal to be pulled away from the trapped body part. The pedal-pulling device is used in order to release the feet/legs of people involved in accidents in motor vehicles trapped by pedals. <IMAGE>

Filed: 1993-09-03
Abstract: A process serves for composting a mixture of organic substances and interfering substances, in particular for composting organic wastes. In order to utilise the organic substances present in the mixture particularly effectively, the organic substances are biodegraded in a closed vessel with forced aeration. The raw compost resulting from this is fed to a sink-float separator (4, 5, 6), in which the interfering substances sink. The substances not sinking in the sink-float separator (4, 5, 6) are again biodegraded in a closed vessel with forced aeration. <IMAGE>

Title: Tear-off lid of sheet metal for a can
Inventor: KORDYLA HANS DIPL ING
IPC: B65D17/34
Filed: 1993-09-24
Abstract: A tear-off lid of sheet metal for a can has a section which is enclosed by a notched line and can be torn off. A tear-off tab designed as a two-arm lever is mounted on this section near to its edge by means of a rivet, one arm being designed as a break-in lug which ends above the notched line and the other arm being designed as a pull ring, below which the lid has a depression. This depression forms a closed flat zone essentially within the boundary and below the pull ring, which zone extends in the direction away from the rivet beyond the pull ring in such a way that the pull ring can be gripped from below by a fingernail. This zone avoids unnecessary deformations and thus the risk of denting or rejection of the lid during production. Additionally, the pull ring can easily be levered up. <IMAGE>

Title: Optical frequency splitter using Bragg diffraction directional couplers
Inventor: NOWAK WALTER PROF DR ING
IPC: G02B6/34
Filed: 1993-10-18
Abstract: The zero-dB fused optical fibre coupler comprises two fibres (1,2) with their cores (4) and GeO2-doped sheaths (5) combined over the coupling region (6), in the centre of which a Bragg grating (3) of relatively short length is produced by photo-refractive effect. The radial distribution of dopant in the fibre sheaths may allow for the different field distribution of LP01 and LP11 waves so that the effective variation of refractive index is the same for both modes, and polarisation dependence is reduced.
