Title: Plunger system for modulating a brake pressure
IPC: B60T8/50
Filed: 1987-10-15
Abstract: A plunger system in a brake line between a master brake cylinder and a wheel brake cylinder of a vehicle, for modulating a brake pressure in the event of a sensor-detected danger of wheel locking or wheel spinning. The plunger system has a plunger that is axially displaceable in a housing. At one end, the plunger engages a variable pressure chamber toward the master brake cylinder and at the other it engages a variable pressure chamber toward the wheel brake cylinder. It has an axial bore, through which a rod passes, between the two pressure chambers, and this bore can be closed on opposite ends if there is a danger of wheel locking or if wheel spinning occurs. The closure of the axial bore is effected by an axial motion of the plunger, which takes place if the wheels lock, on the one hand, and if they spin, on the other.

Patent EP-0240231-A3 (EP)
IPC: G11B20/18
Filed: 1987-03-25
Abstract: Improvements in magnetic recording and reading are 
achieved by providing amplitude qualification thresholds in two 
modes of operation, one a read-after-write mode and the other a 
read-only mode.  
     In the read-after-write mode a fixed amplitude qualifi­
cation threshold (15a) is used which is typically fifty percent 
of the peak value of a perfect dropout-free signal.  
     In the read-only mode the amplitude qualification 
threshold (15a) is derived from the average peak rectified read 
signal (15), and varies with it. The threshold (15a) is selected 
to provide that fraction of the average peak rectified signal 
(15) which gives the lowest acceptable error rate.

Title: Polyalkylamine complexes for ligand extraction and generation
IPC: C02F1/20
Filed: 1988-02-24
Abstract: Methods and apparatus for electrochemical 
extraction of a ligand such as molecular oxygen from a 
first fluid environment and for release of a ligand 
such as molecular oxygen, as well as ligand carrier 
compounds therefor comprising linear, pentadentate 
polyalkylamines and transition metal ions. The carrier 
compounds have the general formula: 
  
where:  
    M is an electrochemically active transition 
metal ion;  
    R₁ and R₂ are each organic groups including a 
nitrogen coordinated to M;  
    m, n, o, and p are each 1, 2, 3, or 4; and  
    X is selected from the group consisting of 
2,6-pyridyl, 2,6-piperidyl, 2,5-pyrrolyl, 2,4-imidazolyl, 
substituted heterocyclic amines, -O-, -S-, -P-, and 
-N-R₃ where R is hydrogen lower alkyl, or aralkyl.  
     By providing an electrocatalyst capable of 
rapid electron transfer and having an electropotential 
less than that of the carrier compound, low energy 
electron transfer between the carrier compounds and the 
electrode of the electrochemical cell is achieved. 
The use of electrodes having catalytically active 
surface sites leads to efficient electron transfer 
between the carrier compounds and the electrodes of the 
electrochemical cell, resulting in lower energy consump­
tion and/or increased oxygen output.

IPC: G01R35/00
Filed: 1988-01-05
Abstract: A method of calibrating a process computer, of the 
kind including an analogue to digital converter for 
converting analogue input signals representative of 
measured process parameters into digital signals for 
processing within the computer, and a digital to 
analogue converter for converting the processed 
signals into analogue output signals, comprises 
applying a known analogue signal to the analogue to 
digital converter, comparing the resulting digital 
signal with its expected value, and computing and 
storing a first calibrating correction value in 
dependence on the difference. A known digital signal 
is then applied from within the computer to the 
digital to analogue converter, whose output is 
coupled back to the input of the analogue to digital 
converter for conversion thereby and correction in 
accordance with the first calibrating correction 
value. A second calibrating correction value is then 
computed from the difference between the corrected 
output of the analogue to digital converter and the 
known digital signal, the second value being stored 
for use in relation to the digital to analogue 
converter.

IPC: H01L21/302
Filed: 1989-09-09
Abstract: A plasma etching system includes a radio 
frequency generator (12) and a parallel plate plasma reactor 
vessel (14). A phase inverter circuit is used to couple the 
RF generator to the electrodes (19, 21) in the plasma reactor (14) so 
that the electrodes (19, 21) are driven with voltages of 
substantially equal magnitude but which are 180° 
out-of-phase. In this way, a maximum potential 
difference between the electrodes can be achieved while 
minimizing the potential difference between the 
individual electrodes (19, 21) and the reactor vessel (14). Such 
operation allows higher power levels with reduced 
occurrence of arcing and stray discharge, and provides 
a stable, uniform plasma discharge.
