Title: Vehicle automatic transmission controller with hydraulic adjustment correction - operates independently on frictional elements of two mechanisms coupled in series for changes of transmission ratio
Inventor: IKEBUCHI TETSUO
IPC: F16H61/02
Filed: 1993-01-15
Abstract: The drive is transmitted from a pump-turbine fluid clutch (14, 15) to a wheelset propeller shaft (40) via two gear-changing mechanisms with hydraulic controls (100).

Title: Method and apparatus for drying metal chips
Inventor: MAURER JOHANNES DIPL ING
IPC: F26B5/04
Filed: 1993-02-25
Abstract: The present invention relates to a method and an apparatus for drying or de-oiling metal chips such as accumulate during chip forming in metalwork. The drying or de-oiling of such chips is effected in a working space (2) which can be evacuated by means of a vacuum pump (5) and heated. According to the invention, provision is made for an induction coil (3) to be used for the heating. The induction coil (3) directly heats up the metal chips to be dried or de-oiled. Uniform heating of the chips can thereby be effected and a reduction in the drying time can be achieved. The method according to the invention is used in particular in the case of oily grinding swarf which has to be separated into its oil and metal-chip constituents. The inductive heating of the wetted metal chips is preferably carried out to a temperature of between 200 DEG C and 300 DEG C. <IMAGE>

Inventor: TOEREMIS GOENUEL
IPC: D06F89/00
Filed: 1993-04-08
Abstract: It has hitherto been difficult to fold fitted bed sheets by hand so that they can be stowed properly in cupboards.

Title: Method and arrangement for drift correction of temporally discrete measurement signals relative to a reference signal, in particular in absorption-spectroscopic trace-gas analysis
Inventor: WERLE PETER DR
IPC: G01N21/39
Filed: 1993-06-17
Abstract: The invention relates to a method and an arrangement for drift correction of temporally discrete measurement signals relative to a reference signal, in particular for application in absorption-spectroscopic trace-gas analysis. By means of the invention, it is intended to increase the accuracy of the measurement signals obtained over a multiplicity of spectra or scans. For this purpose, an on-line drift correction is provided, which can be used, in particular, in spectroscopy using semiconductor diode lasers, but also in all other measurement methods in which signal drifts may lead to deterioration of the measurement result. Since an on-line analysis and correction of the relative shift between measurement and calibration spectrum or the reference signal are first carried out before the respective data are compiled by averaging, the otherwise required storage of a large number of raw spectra for subsequent off-line analysis is obviated. The on-line drift correction method according to the invention can be implemented both purely using hardware or purely using software and in a combination of hardware and software. <IMAGE>

Title: Circulating fluidised bed system esp. for coal combustion with pollutant removal
IPC: C10L10/00
Filed: 1993-12-24
Abstract: A fluidised bed reactor (fig. 8a,b) its ancillary equipment and modes of operation are new. A feature of this system is the downward recirculation of material lifted by the vortices in the fluidised bed; hence upwardly- and downwardly directed flows co-exist. The equipment is considered suitable for any combination of physical, chemical and biological processing with stationary, highly expanded or recirculating fluidised beds.  The ancillaries may be attached in various configurations for these processes. It is especially suitable for the combustion of various fuels; among the claimed procedures are the fixation of sulphur by lime or dolomite addition, and similarly the removal of halogens, for example chlorine and fluorine, at less than 600  deg  C; implying particular suitability for the fluidised combustion of coal. The hybrid recirculation mode claimed, promotes a fixed fluidised bed of coarser material, and a mobile portion of finer material.  The use of a catalyst, e.g. vanadium pentoxide, to reduce NOx, with an ammonia, ammoniacal liquor or urea spray injection into the stationary fluidised bed, are also claimed. Further ancillary systems and configurations are claimed.
