Patent DE-4225506-A1 (DE)
Title: Strips prodn. e.g. for retreading used tyres - by passing uncured strip between suitably profiled roller and at least one smooth roller, and curing as required
Inventor: SCHIMANEK KARL
IPC: B29D30/66
Filed: 1992-08-01
Abstract: A profiled roller moulds uncured strips of material so that they have a relief pattern in the surface, whose positive projections form the intermediate grooves in the tread of tyres. In the process the strip passes between the profiled and at least one plain roller, so that the pattern of the profile is pressed into it. The figure shows uncured strip (9) passing between the profiled roller (2) and smooth rollers (1). The former roller (2) has a relief pattern so that proud parts (37) produce correspondingly profiled grooves (38) in the strip (14). The profiled strip (14) thus passes over another plain roller (1) and can then be cured. Its cure can be by hot pressing or by h/f. The finished strip can then be further processed in conventional manner. The pattern on the roller (2) can be produced by making the roller up from appropriate discs which are assembled together, with or without intermediate spacers as necessary. ADVANTAGE - The method greatly simplifies production of tread strip. It saves much time, energy, subsidiary materials, tools and material storing costs. It is particularly economical for retreading commercial vehicle tyres so that used tyres will become more abundant and hence save wastage of tyres.

Patent DE-4235151-A1 (DE)
Inventor: KROGGEL MATTHIAS DR
IPC: C08F8/28
Filed: 1992-10-19
Abstract: Polyvinyl acetals which are capable of forming emulsifier- and surfactant free aqueous dispersions and redispersible dry powders and contain copolymeric polyvinyl acetals containing amounts, sufficient to form a dispersion, on sulfo salt group-carrying comonomer units derived from copolymeric polyvinyl alcohols (PVALs) which contained sulfonate group-carrying comonomer units in the salt form are prepared by acetalation of the starting polyvinyl alcohols to be used by means of aldehydes or aldehyde acetals under acid-catalysed acetalation conditions in aqueous medium, giving emulsifier-free, stable, aqueous polyvinyl acetal dispersions from which dry, redispersible polyvinyl acetal powders can be obtained by spray drying or freeze drying. The novel polyvinyl acetals can be plasticised both in their aqueous dispersion form and in the dry powder form by mixing in plasticisers. The novel polyvinyl acetals can be employed both in the aqueous dispersion form and in the dry powder form in numerous areas of application in which polyvinyl acetals of the type known hitherto are usually already used. In addition, the advantageous property profile of novel polyvinyl acetals makes numerous new areas of application accessible.

Title: Method of hydraulic tomography to identify spaced permeability in subsoil - involves forming non=stationary flow fields whose permeability is numerically reconstructed by pore water pressure and volume flow measurements
Inventor: GOTTLIEB JOHANNES DIPL ING
IPC: E21B49/00
Filed: 1992-10-30
Abstract: Non-stationary flow fields are produced by transient or timewise periodical sources and depressions, the extent of which is observed by pore water pressure measurements. A permeability distribution is numerically reconstructed from these measurements together with the volume flow and pressure of source and depression. The non-stationary flow fields are produced, in that water through conduits or pipes of reasonable flexibility is pressed into the ground or sucked out of it. The input and/or suction of water at one or more points occurs simultaneously. The position for pressing into the ground or suction from it after prodn. and observation of a non-stationary flow recess is altered, in order to produce and observe new non-stationary flow fields with altered throughflow directions. USE - In tunnel construction and environmental protection.

Title: Rock anchor with limited yielding capacity
Inventor: KASSELMANN JOCHEN DIPL ING
IPC: E21D21/00
Filed: 1993-09-27
Abstract: A rock anchor with limited yielding capacity is provided with a shaped part in the area of the borehole mouth. The shaped part consists of a sleeve, secured to the borehole mouth and put into the concrete shell, and a piston enclosing the anchor rod. The piston is provided with an outer jacket which cuts into the inner wall of the sleeve when the rock anchor yields. An essentially uniform characteristic is thus achieved over the entire displacement and it is ensured that there are no longer parts of the rock anchor which project beyond the concrete shell. The latter especially applies when the sleeve is secured in the concrete shell, is flush at its outer margin with the concrete shell, and when a recess into which the anchor nut and the end of the anchor rod can plunge is provided in the piston. In addition, such a rock anchor can be readily manufactured to a uniform quality and also in a design adapted to the respective application. <IMAGE>

Title: Pulse generator contg. semiconductor switch and saturable transformer - uses charge transfer between capacitors in sec. circuit having saturable choke in parallel with discharge path
Inventor: INATOMI HIROSHI
IPC: H03K17/80
Filed: 1993-10-08
Abstract: The generator has a capacitor (CO) which is charged to a high voltage from a DC source, and discharged through a saturable transformer (SI1) and the prim. winding of a step-up transformer (T) by a GTO thyristor, static induction thyristor or IGBT (SW). The choke provides magnetic assistance to reduce the switching loss. A sec. current (I1) enters the saturable transformer, charging a second capacitor (C1) and magnetising a second saturable choke (SI2) until the transformer becomes satd. and reverse current (I2') transfers the charge to a third capacitor (CP), building up sufficient voltage to ignite the discharge tube (DT). USE/ADVANTAGE - For laser pulsing, plasma prodn. or denitrification, short pulses of heavy current can be generated at high voltage with reduced semiconductor switching voltage.

Title: Bicycle pedal drive with torque maximisation
Inventor: STINGL BERNHARD
IPC: B62M9/10
Filed: 1994-02-28
Abstract: A pref. spring loaded rocking arm, fixed to the axle of a pedal arm, connects the pedal arm with a toothed gear wheel. A fixed disc adjacent to the rocking arm has a raised portion which acts on the arm over a predetermined sector of its circular path, removing the link to the gear wheel.  This sector is chosen to correspond to the period when torque is low. The pedal arm can therefore move on quickly towards an optimum sector, when the torque is restored automatically.

Abstract: A method of evaluating signals comprises the step of convoluting a first signal (S1), which is to be evaluated, with a second signal which represents a step function of zero mean value, and recognising from the course of the convoluted signal (S3), such as by comparison with a threshold (UG2), whether an expected event has taken place. Different events can be recognised and localised by comparison of the signal (S3) obtained from the convolution with patterns to be expected. In addition, signal courses can be checked for plausibility either directly or after a convolution with a further signal for diagnosis or fault recognition. <IMAGE>
