Title: Drying of flowable paste-like prods. e.g. coal - using indirectly heated fluidised bed to increase pressure
Inventor: WOLF BODO DR
IPC: F26B21/04
Filed: 1991-05-15
Abstract: In the drying of flowable, paste-like products (I) contg. 5-98 wt.% water, indirectly heated fluidised bed is used, out of which, after heating, the resulting steam and fluidised medium leave as waste steam, fluidised with part of the waste steam after puriicn., esp. dedusting, by recirculation and utilisation of the waste steam. The technical work required for the recirculation enables a pressure increase by 5-50 kPa completely or partially by expansion of the waste steam of 95-150 kPa by removing work of less than 10 kPa using condensation, working in this pressure-range, which is produced in the fluidised bed by indirect heat transfer. Also claimed is the apparatus for the above process. USE/ADVANTAGE - For coal, esp. lignite or slurries. The process is suitable for use in industry, construction industry and agriculture.

Title: Calibrating torque computers for DC machines - using three calibration stages in which various torques are measured and all error moments between internal torque and torque sensor are detected
Inventor: BENDEL REINHOLD
IPC: G01L25/00
Filed: 1991-06-13
Abstract: A method of calibrating single loss torque computers for d.c. machines involves a first calibration stage with the machine unloaded in which the internal torque is measured for a number of speeds within the speed range and with operational excitation and is stored as the sum of the frictional and eddy current torques. This is repeated for an unloaded machine with a characteristic core current and the torque stored as the sum of the friction and loss torques. The frictional torques are determined for the speeds with a given inertial torque. The eddy current, loss and total error moments are derived. The accleration torque is determined in a third calibration step, enabling the inertial moment and speed variation to be derived. USE/ADVANTAGE - Enables all static error torques between internal torque and torque sensor to be detected.

Title: Spinning frame - has the drive-shafts for the drafting rollers in sections with a corresp. threaded joint
Inventor: LATTION ANDRE
IPC: D01H1/22
Filed: 1992-04-07
Abstract: On a spinning frame the drafting rollres are driven by the three bottom shafts from the end gearing. The drive shafts are in more than one section, and joined together at the section ends by an exterior and interior thread. The hand of thread is selected so that they bind together according to the direction of the drive, and relative speed. The motor drives the headstock gearing, so tha shaft are driven in a relative manner, enabling the fibre to be drawn out between the rollers, as the back rollers rotate at a slower speed than the output rollers. The sections of driveshaft are combined by the threaded joint, with all shafts moving in direction. The joints are repeated at various positions across the frame. ADVANTAGE - The erection of the frame and shafts is simplified. The design is of particular advantage during the maintenance of the frame.
