Title: Weak-current dynamo
Inventor: KNUTZEN HANS-PETER
IPC: B62J6/12
Filed: 1983-06-18
Abstract: A weak current dynamo having a gear drive in a hub is very particularly suitable for reducing the risk posed by traffic to cyclists at dusk and in the dark, particularly in damp weather conditions, since failure due to environmental influences is impossible. The intermediate wheel which is continuously engaged increases the tractive resistance only so slightly that this is not noticeable with a normal cycle. Only the switched-on dynamo will, as the case may be, increase the tractive resistance, as in the case of the conventional dynamo. The structure and production of the weak-current dynamo are relatively simple, e.g. the hub can be produced using the deep-drawing process, the open side contains external or internal threads for a bearing plate, the gear rim and the intermediate wheel are produced from plastic (nylon, Macrolan or the like) using the extrusion process and brought to the required length, the armature (rotatable) and holder (fixed) for the coils and permanent magnets, respectively, are compression moulded from plastic in such a way that the coils or permanent magnets are only clamped. The intermediate wheel and the armature are mounted in maintenance-free Teflon bearings. The material qualitites of the gear wheels are selected such that the intermediate wheel (most inexpensive part) is the first and the gear wheel on the armature (most expensive part) the last to wear. The two wheel antifriction bearings are, as usual, lubricated with oil, i.e. this oil is distributed in the hub by the rotation, as experience shows, and thus the sliding...

Title: Visco-elastically damped torsional vibration absorber with spring-coupled fly-ring
Inventor: FEDERN KLAUS PROF DR ING
IPC: F16F15/173
Filed: 1984-06-21
Abstract: Viscously damped torsional vibration absorbers are increasingly being equipped with additional coupling springs or springs which elastically centre the damping ring in the housing. In order to prevent the displacement of the viscous medium by the alternating displacement of spring portions and to keep the space taken up by the viscous medium in the gap between the damper ring and the housing as small as possible, the space occupied by the additional springs is, according to the invention, separated from the gap space containing the viscous medium by elastically dynamically deformable elastomers. As a result, there is greater freedom in the optimisation of the shape of the springs, and the strongly temperature-dependent displacement damping and displacement stiffening by the alternating spring deformation is eliminated.

Title: Continuously variable planetary gear mechanism
Inventor: HILS KARL
IPC: F16H37/02
Filed: 1985-05-08
Abstract: The invention relates to a planetary gear mechanism which is made up of a combination of a flexible transmission with a planet-gear stage. Planet wheels revolve translationally around the centre of a sun gear fixed to the casing at an adjustable distance to the said sun gear and take the place of an otherwise customary central gear in forming the centre of revolution of a toothed disc which is connected to them via a flexible transmission member. The reverse rotation effect to which this gives rise establishes a rolling-contact path at the connected external gear which corresponds to the respective setting of the centre of the arrangement of a gear with an adjustable number of teeth fixed to the housing. An internal gear rolls on the external gear with a rotational speed which can be varied starting from zero and is transmitted, with positive engagement, to the output shaft via an eccentricity-compensating device.

Title: Circuit for remote monitoring of a light signal
Inventor: MEIER JOACHIM
IPC: G08G1/097
Filed: 1985-05-08
Abstract: DC voltages are extracted at the signal location via diodes (D1, D2; D3, D4) from a supply circuit (TH, 1, 2, LH) which is continuously switched through as far as the light signal. These DC voltages are injected by monitoring switching means (HU/1, FU/2; HH/2, FH/3) into two separate monitoring circuits and are extracted again at a control point by current-direction-sensitive switching means (OV1, OV2; OV3, OV4) having a low-pass characteristic. The one monitoring circuit leads (in addition to via the continuously switched-through supply circuit) via a supply line (3) of a signal lamp (F) which is not connected, and the other leads instead via an additional line (5) between the light signal and control point. Connection terminals which are at earth potential can be used instead of an additional line. <IMAGE>

Inventor: KRICK WOLFGANG DIPL ING
IPC: H04J3/16
Filed: 1985-10-16
Abstract: Service integration in ISDN is implemented primarily on the subscriber connection line. For connection of the different subscriber terminals corresponding to these services, provision is made at the user/network interface such that one 16 kbit/s common signalling channel D is made available along with the two 64 kbit/s information channels B. The method by which the narrowband terminals gain access to the D-channel is defined in CCITT Recommendation I.430. In a future broadband ISDN with a preferably optical subscriber connection line, high-speed services, e.g. moving picture services, are planned along with the aforementioned narrowband ISDN services. In order now to be able to implement access for broadband terminals also according to the access method defined in CCITT Recommendation I.430, the structure of the broadband pulse frame is selected in the time division multiplex transmission method according to the invention in such a way that the D and E bits occur in each case in individual bits in the pulse frame for the broadband transmission at the interval of roughly half the octet cycle duration (62.5  mu s), the position of the D bits being selected in such a way that an overlap occurs with the position of the D bits for the narrowband transmission access method.
