Title: Electrical flywheel drive for bicycle with aluminium@ or plastics material flywheel disc - located horizontally and driven by electric motor and having spaced radial cavities vertical to its centre to house heavy metal balls
Inventor: THOENE HERMANN
IPC: B62K11/12
Filed: 1992-08-04
Abstract: The balls (4), located in the cavities (2), are made of steel or some other heavy metal, and lie at equal distances vertical to the centre of the flywheel and at exact distances near to its axis. Inserted pressure springs (3) press the individual balls towards the flywheel axis, and are held loaded by screw plugs (5). With diametral movement of the balls (4), due to the regulatable r.p.m. of the motor, the balls react as mass points due to the tensile stress conditioned centrifugal force in the circular movements. The balls activate an automatic oscillation according to the r.p.m. and alter the torque. USE/ADVANTAGE - Fully electrical cycle or power-assisted cycle. Travel range can be increased without use of heavy batteries. Motor can be controlled quickly at high r.p.m. and driving efficiency is increased.

Title: Phenolic resin laminates with good cutting and embossing properties - by impregnating paper etc. with phenolic resin soln. contg. recycled or scrap polyvinyl-butyral, then drying and hot-pressing as usual
Inventor: FASBENDER HELMUT DR
IPC: B29B17/02
Filed: 1992-09-05
Abstract: Laminate or sheet material, or pressed or coiled moulded prods. (I) are claimed. (I) are produced by impregnating paper strips, fleece, woven fabric, etc. with phenolic, cresolic and/or xylenolic resin (II) with addn. of polyvinylbutyral (PVB), followed by drying and hardening in one or more layers at elevated temp. and pressure. The PVB is recycled material or waste prodn. material, in amts. of 5-35 wt.% w.r.t. solids content of resin soln. Also claimed are processes for producing laminated paper (I) and for reprocessing recycled/waste PVB, by adding the PVB, pref. as a soln., to a soln. of (II) as above. USE/ADVANTAGE - The use of recycled or scrap PVB, esp. for laminated glass, as an additive for prodn. of resin solns. (II) is claimed. (I) are used, e.g. as sheet materials, tubes, and semi-finished prods., and for the prodn. of electrical insulating materials, etc. The addn. of PVB (together with the plasticisers contained in the PVB) enables the prodn. of laminated paper with improved properties, i.e. less brittleness, better cutting and embossing properties and better interlaminar bonding; a high resin level can be obtd. with conc. solns.

Abstract: A dental implant comprises an implant body (2) for anchorage in the jaw and a superstructure member (14) which can at least partially be inserted in a recess in the implant body (2) and be fixed by a retaining screw (8). In order to secure it against rotation the recess (4) comprises a first bearing surface (22) and the superstructure member (14) comprises an assigned second bearing surface (24). This dental implant is to be developed further in such a way that the superstructure member is secured against rotation relative to the implant body without play and in a durable and functionally reliable manner. It is proposed that the superstructure member (14) have at least one slot (26) extending from its free end (28) to the region of the second bearing surface, and a radially inward narrowing (34). The retaining screw (8) is assigned a pressure surface (36) which can engage with said narrowing (34) during screwing-in of the retaining screw (8) in such a way that it results in radial dilatation of the superstructure member (14) and, at least partially, firm contact of the first and second bearing surfaces (22, 24). <IMAGE>

Title: Fuel injection system for diesel engine
Inventor: WUEBBEKE KARL DR
IPC: F02M51/06
Filed: 1992-12-22
Abstract: The fuel injection system for a diesel engine has the driving parameters evaluated by an electronic unit and output signals are generated which are passed directly to electromagnets at the injection nozzles, where they control the fuel metering. New output signals are generated whenever any driving parameter changes and there is one signal per cylinder or group (eg pair) of cylinders. The electromagnet of an injector works on an armature plate which in turn works on the piston. This piston is held closed by a spring and opens only when a signal is received. The piston diameter is much larger than that of the nozzle openings.

Title: Method for the prognosis of inhibitor or toxicological carcinogenic action of organic nitrogen compounds
Inventor: ADLER BERNHARD PROF DR
IPC: C07C211/50
Filed: 1993-03-26
Abstract: The invention relates to a method for the prognosis of inhibitor or toxicological carcinogenic action of organic nitrogen compounds, especially aryl amines before the start of chemical synthesis. This prognosis is carried out using a base data set of structures hitherto experimentally evaluated as safe in regard to their action with the use of various pattern-recognition methods such as, for example, fuzzy clustering, primary-component analysis or the use of neuronal networks. In this case, simulation results are accepted only if the same classification results are obtained for the pattern recognition using different characteristic sets and different mathematical models.

Patent DE-4321087-A1 (DE)
Inventor: HANNEFORTH WOLFGANG PROF DR IN
IPC: B61F5/30
Filed: 1993-06-21
Abstract: Running gear for railway vehicles, which, by virtue of the particular arrangement of the damping components, improves damping, permits high travel speeds and ensures that bends can be travelled through safely. This object is achieved by means of the arrangement of the vertical and horizontal shock absorbers in such a way that as a result of the horizontal shock absorber force a rotational deflection of the axle bearing housing is produced, which rotational deflection is in turn additionally damped by the vertical shock absorber, the longitudinal movements of the wheel sets being simultaneously damped by the horizontal shock absorber and the vertical shock absorber and this also applying to a lesser degree to the transverse movements of the wheel sets. The vertical shock absorber is included in the damping characteristic of the horizontal shock absorber. By changing the attachment point of the horizontal shock absorber and thus by changing the points of intersection of the median lines of the shock absorbers and the median line of the axle bearing housing in the vertical and horizontal planes by means of an attachment bracket arranged in a defined manner it is possible to vary the damping ratio of the shock absorbers. The invention is suitable in particular for sets of running gear which are to be used for high speed transport. <IMAGE>

Title: Spare reels wound onto compressible support tube - has inner and outer ring areas which are wound with greater tension in outer ring area to retain compact compressed storage shape until used
Inventor: WERTHMUELLER CHRISTIAN
IPC: B65H23/195
Filed: 1993-06-25
Abstract: The reel (2) has an inner ring area (3) enclosed by an outer ring area (4). The material in the outer ring is wound up under a greater tension than the material in the inner ring and the elongation difference thereby caused between the two rings is at least 10 % of the breaking strain of the material web. The tension can be raised by increasing the circumferential speed of the spare reel during winding in relation to the entry speed of the material web. The winding machine has a programmed winding curve with an increase in the end area. ADVANTAGE - The reel can be compressed for transport and storage and then returned to its original shape for use.
