Patent EP-0191619-A3 (EP)
IPC: H03H19/00
Filed: 1986-02-10
Abstract: An automatic linear compression circuit for a telephone 
«handsfree» loudspeaker is provided. The circuit consists of a 
variable attenuator the level of attenuation of which is con­
trolled by the input signal level. The input signal is passed 
through a positive peak detector to obtain a time averaged sig­
nal corresponding to the average positive peak values of the in­
put signal and this time average signal is compared against a 
time increasing reference voltage. As long as the reference vol­
tage is below the value of the time averaged signal a positive 
attenuator control signal is derived. This positive control signal 
keeps the attenuator portion of the circuit operative. In the at­
tenuator the input voltage is sampled to a first capacitor. The 
first capacitor is subsequently connected to and disconnected 
from a second capacitor a number of times as long as the posi­
tive attenuator control signal is present. Each time this is done 
the voltage on the first capacitor is reduced by a factor depend­
ing on the capacitances of the two capacitors. After a predeter­
mined time the voltage remaining on the first capacitor is 
passed through buffers and another capacitor to provide an 
attenuated output. The circuit is simple and flexible, permitting 
wide ranges in the operating parameters to be achieved simply 
by including one or more variable capacitors.

Title: Process for the preparation of lmw-heparin
IPC: C12P19/04
Filed: 1987-04-29
Abstract: A method for production of low molecular weight heparin (LMW-heparin) bv enzymatic depolymerization of heparin with heparinase wherein heparin is continuously fed to a depolymerization zone, the depolymerized LMW-heparin is ultrafiltrated, the retentate is recycled to the depolymerization zone and LMW-heparin is recovered from the filtrate. The process enables the production of LMW-heparin with a desired molecular weight and low polydispersity within narrow limits by continuously or frequently measuring the molecular weight and polydispersity of the LMW-heparin product and correction of process parameters of the depolymerization reaction so as to counteract deviations in the molecular weight and polydispersity from the desired values.

Abstract: The state of inflation of inflatable tyres of a 
vehicle is monitored by providing a transducer output 
dependent on the load experienced by each wheel, by 
generating from the outputs a signal representing the 
instantaneous value of the warp load of the vehicle, 
and producing an output representing the rate of change 
of the average warp load. This output is compared with 
a reference signal representing a predetermined rate of 
change of average warp load, to energize indicating 
means when the output exceeds the reference signal. 
The indicating means can indicate a deflation condition 
to the driver of the vehicle and/or to the driver of a 
following vehicle. Vehicle speed can be limited in 
response to a detected deflation condition.

Title: Graphic display system with secondary pixel image storage
IPC: G06F3/048
Filed: 1988-10-25
Abstract: An improved graphics display system includes a 
picture processor for processing display lists 
defining graphic designs, the display lists 
comprising pixel data and/or instructions for 
generating pixel data. The system further includes 
a display controller which stores pixel data in a 
frame buffer memory and controls a display of 
graphic designs in accordance therewith. When a 
display list defining a graphic design is changed 
but the design is not to be displayed, the display 
list is processed by the picture processor, but the 
output pixel data generated by the picture 
processor is routed not to the display controller 
but to a control processor which stores the 
generated pixel data in a second memory. When the 
design is thereafter to be displayed, the control 
processor generates a secondary display list 
including the pixel data stored in the second 
memory to the picture processor. The picture 
processor then forwards the pixel data included in 
the secondary display list to the display 
controller for storage in the frame buffer memory 
so as to initiate display of the graphic design.

Title: Method for removing stains from fabrics and product to carry out this method
IPC: C11D1/65
Filed: 1989-03-31
Abstract: The removal of stains from fabrics is difficult because of the different chemical composition of staining substances, which extends from plant juices to coloured pastes, for example ballpoint paste. To date, stain removers suited to the particular staining substance have been employed both domestically and in commercial cleaning. Since the customary stain removers contain volatile, often flammable solvents, a possibility for long action times, which in conjunction with water brings about reliable washing out of the coloured pigments, has been achieved by treatment with stain removing components which do not contain volatile solvents.
