IPC: H04M19/00
Filed: 1984-08-23
Abstract: An interface circuit for providing power and signal volt­
ages to a telephone line under the control of a microcomputer 
within the telephone exchange comprises four charge pumps, 
each comprising a pair of driver/amplifiers which charge a pair 
of capacitors through a first diode with two further diodes dis­
charging the capacitors to charge a capacitor connected 
across the telephone line. The four charge pumps are arranged 
symmetrically to provide positive and negative potential at the 
tip terminal and positive or negative potential at the ring termi­
nal. Modulation of the voltages to transmit a desired signal is 
obtained by modulating the power voltage supplied to the am­
plifier/drivers. The current drawn by telephone line is measured 
by sending the current drawn from the voltage source by the 
amplifier/drivers and this is used to extract the receiving signal 
from a telephone line and also to extract a measurement of 
peak current drawn from the tip and ring leads separately. The 
amplifier/drivers are diven by continuous square wave signal.

Patent EP-0176893-A3 (EP)
Title: Time base corrector
IPC: H04N5/956
Filed: 1985-09-20
Abstract: In a time base corrector incorporated a video tape recorder, if a time during which a vertical synchronizing signal is written in a memory unit (2) exceeds one horizontal period segment, the video signal stored at the first address of the memory unit (2) is dropped out during data reading operation. To overcome the above problem a write address designation signal (ADW) is once latched in response to a vertical synchronizing signal (PBV) a predetermined number is subtracted from the latched address number; the subtracted a address number is loaded in a counter (16) in response to a reference vertical synchronizing signal (REFV) and is incremented in response to a reference horizontal synchronizing signal (REFH) in order to shift the read start address, thus preventing video signals stored in the memory unit (2) from being dropped off.

Abstract: The invention provides a silanised layered clay comprising 
a layered clay chemically modified by incorporation therein of 
a silicon-containing residue in the absence of a polymeric cati­
onic hydroxy inorganic metal complex. The silanised layered 
clays are produced by hydrolysing a hydrolysable silicon com­
pound, for example a tetraalkoxysilane, in the presence of the 
layered clay and in the absence of a polymeric cationic hydroxy 
inorganic metal complex. The resulting silanised layered clays 
are more thermally and/or hydrothermally stable than the lay­
ered clays from which they are derived.

Patent EP-0155244-A3 (EP)
IPC: C07D401/04
Filed: 1985-03-08
Abstract: The title compound 1-ethyl-6-fluoro-7-(1-pyrrol-1-yl)-­
1,4-dihydro-4-oxoquinoline-3-carboxylic acid is a quinolone 
carboxylic acid derivative of "oxacin" family bearing a fluor­
ine atom and a pyrrol-1-yl moiety at 6 and 7 position respec­
tively. It is represented by the following formula: 
  
and has been prepared by alkaline hydrolysis of the corres­
ponding ethyl ester. The latter compound has been syn­
thesized starting from 2-fluoro-5-nitroaniline. Treatment of 
this amino with diethoxytetrahydrofuran in glacial acetic acid 
afforded 4-fluoro-3-(1-H-pyrrol-1-yl)-nitrobenzene, which 
was then reduced by catalytic hydrogenation to 4-fluoro-3-­
(1H-pyrrol-1-yl)aniline.  
     Reaction of this compound with diethyl ethoxy­
methylene malonate and cyclization of the malonate ob­
tained by heating in diphenyl ether at 120°C resulted in 
formation of ethyl ester of 6-fluoro-7-(1H-pyrrol-1-­
yl)quinoline-3-carboxylic acid. Ethylation of this ester with 
ethyl iodide in the presence of sodium carbonate gave 
the required 1-ethyl-6-fluoro-7-(1H-pyrrol-1-yl)-1,4-dihydro-­
4-oxoquinoline-3-carboxylic acid ethyl ester.  
     The title acid exhibits high activity against Gram-­
positive bacteria, Enterobacteriaceae, Proteus and Pseudo­
monas, superior to those of nalidixic acid, piromidic acid and 
pipemidic acid; again, its antimicrobial spectrum is some­
what superior also to that of enoxacin.  
     1-Ethyl-6-fluoro-7-(1H-pyrrol-1-yl)-1,4-dihydro-4-oxo­
quinoline-3-carboxylic acid is a new potent fluorinated quin­
olone antibacterial agent useful in the management of urin­
ary tract and systemic infections.  
     The present invention also relates to a process for the 
preparation of such compound.
Patent EP-0218859-A3 (EP)
IPC: H04Q11/04
Filed: 1986-08-26
Abstract: A communication interface for providing asynchronous and 
telephonic communications is disclosed. The interface 
enables software applications, which are independent of any 
hardware or physical addresses, to operate on the interface. 
In this manner, the software applications can be written 
independent of hardware implementation and protocol 
implementation. A set of configuration parameters is defined 
for both an asynchronous and telephonic communication 
function set. Additionally, a set of interrupt conditions 
is defined for both the asynchronous and telephonic 
communication function sets. These parameters and interrupt 
conditions control the interaction of the software 
applications across the interface with the system hardware. 
Means are provided for directing commands coming from a 
software application across the interface to the system 
hardware. Likewise, means are provided for generating 
interrupts and handling these interrupts from the system 
hardware across the interface back to an interrupt routine 
within the software application.

Ladeluftspeicher (12) gebildet. Die von der Ladeluftpumpe 
(3) geforderte Ladeluft tritt in den Ladeluftspeicher (12) ein, 
um von dort über Einlassventile (20, 21) in die jeweiligen 
Verbrennungsräume (9, 10) einzutreten. Die von der Flüssig­
keitspumpe (2) geförderte Flüssigkeit strömt in einen Wind­
kessel (60). Von diesem strömt die Flüssigkeit weiter in eine 
Flüssigkeitsturbine (66), wobei die nutzbare Energie über die 
Turbinenwelle (67) abgegeben wird. Da die Flüssigkeit 
unkompressibel ist, erfolgt die Kraftübertragung von der 
Flüssigkeitskolbenpumpe (2) zur Turbine (66) mit nur sher 
kleinen Verlusten. Damit ist ein besserer thermischer Wir­
kungsgrad der Brennkraftmaschine sichergestellt. Die Brenn­
kraftmaschine ist äusserst einfach und gedrängt gebaut. Es 
ist nur ein Zylinder (1) notwendig, um eine praktisch 
gleichförmige Leistung an der Turbinenwelle (67) zu 
erzeugen.

Abstract: A method of controlling current in an AC motor to 
inhibit small torques on an unloaded motor output shaft and 
to improve buildup of steady-state operating flux in a rotor 
includes supplying current to the stator windings through a 
plurality of semiconductor switches, operating the semicon­
ductor switches to supply a plurality of gradually increasing 
currents to the stator windings over a time interval corres­
ponding to approximately one rotor time constant to bring 
flux in the rotor up to approximately 10% of a steady-state 
operating flux in the rotor, operating the semiconductor 
switches to supply a current that is the maximum current 
rated for pulsed operation of the semiconductor switches for 
a time interval over which a product of current and time is 
sufficient to produce steady-state operating flux in the 
rotor, and then reducing the stator current to a level for 
maintaining steady-state operating flux in the rotor. A 
microelectronic apparatus for carrying out the method is 
also disclosed.

the back check lever (3), and the grand whippen, in 
turn producing rotation of the catcher arm (23) which 
drives the hammer (27) towards the string (30). The 
catcher arm (23) has a catcher (45) at its forward end 
and the back check lever (3) has a back check (46) for 
catching the catcher after the hammer has rebounded from
