Title: Polymerisation to form granules of crosslinked unsaturated polyester.
IPC: C08F283/01
Filed: 1980-12-05
Abstract: Process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter. Previously known processes for the preparation of granules of this type has utilised polyamines this as led to odour and colour problems. These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used the pKa value of the conjugate acod of the anion is greater than 2. The process of this invention consists of polymerising a carboxylated unsaturated polyester with acid values between 5-50 mg KOH/g and //c, ss-ethylenically unsaturated monomer by a double emulsion process and in the presence of a base referred to above. The resulting granules are useful as matting and opacifying agents in, for example, paint compositions.

Title: Apparatus for separating sand from botanical fines
IPC: A24B1/04
Filed: 1981-08-04
Abstract: A mixture of botanical fines and sand is separated by a porous separating medium horizontally disposed within an enclosed chamber in which an upflowing stream of gas carries out the separation. The porous separating medium is comprised of a pair of opposed rotatively movable juxtaposed porous members with means for rotatively adjusting the porous members so as to change the flow through area in the porous separating medium. As a gas flows up through the porous separating medium, only the sand passes down through the porous medium and the gas entrains the botanical fines portion of the mixture above the porous members removing the botanical fines with the gas stream. Control of the velocity of gas up through the porous medium as well as the prevention of botanical fines from flowing with the sand down through the porous medium is determined by the adjustments of the rotatively mounted porous members.

Title: Process and apparatus for moulding articles from binder-containing organic fibrous mats
IPC: B29C51/08
Filed: 1982-10-07
Abstract: A process, with the associated apparatus, forms molded articles from binder-containing organic fibres. The process uses pressure to achieve temperatures of more than 100 DEG C. The material is preferably in the form of fibrous mats containing up to 50% heat-hardening binder and having a processing moisture content of more than 5% and preferably 10 to 25%. The compression of the material structure takes place in a single mold stroke, optionally accompanied by additional shaping. With the mold closed, steam pressure is produced during the minimum curing time of the binder in a closed, material-containing volume. The mold is maintained at a superatmospheric pressure. Additional steam can be introduced before or during this time. Following the minimum curing time, the steam pressure and moisture in the molded material are reduced without any significant change to the mold temperature and during steam pressure release the molding pressure is not reduced below a value required for keeping the mold steam tight and for maintaining a surface pressure. This molding pressure is at least equivalent to the steam pressure in the material. At the end of steam pressure release, the molding pressure is released and the mold is opened for removing the workpiece.

Title: Arrangement for detecting the slipping of the wheels of running axle-less rail power units
IPC: B60L3/10
Filed: 1982-12-14
Abstract: The invention relates to an arrangement for detecting the slipping of the wheels of running axle-less rail power units, in which proportional voltages associated with the speeds of revolution of all the wheel axles are compared with a reference speed of revolution or voltage emitted by an integrator as a pseudo-running axle and the differences occurring in speed of revolution comparators are evaluated in order to reduce the drive forces or brake forces at the respective axles, control variables corresponding to the desired traction force values accelerating the power unit and those of a comparator being fed to the integrator in order to influence the integration speed, which comparator in each case forms the difference between the reference voltage and a selection of all proportional voltages corresponding to the speeds of revolution of the wheels. In order to avoid the errors with detected integration speeds and to be able to continuously match the integration speed to the actual acceleration, it is proposed according to the invention that the control variable desired traction force value (Zsoll) be fed to the integrator multiplied by a reduction factor </= 1 which is dependent on the continuous comparison of the acceleration value with the actual traction force value or corresponding proportional variables. At the same time, the control variable of the dsired traction force value (Zsoll) is modified by means of a multiplying digital-to-analog converter (30) to which a reduction factor which corresponds to the counter state of a counter (31) is fed, in which case the counting operation and counting direction of the counter (31) are dependent on the comparison of the actual acceleration value (bist) with the actual traction force value (Zist).
