Patent EP-0160304-A3 (EP)
IPC: G01M11/00
Filed: 1985-04-30
Abstract: A method and an apparatus for measuring the fiber 
orientation of papers (14) that include throwing the infrared 
light to papers of a cutting out test from paper products or a 
moving sheet on a paper machine, wherein the infrared light 
being transmitted through or reflected by papers, is mea­
sured to detect the degree of attenuation caused by the 
absorption effects of the papers (14). The measurement is 
made with polarized infrared light and the direction of 
polarization is changed. The detection signals are processed 
so as to indicate the fiber orientation as a plot in polar 
coordinates. Alternatively, the polarization may be first made 
before throwing the infrared light at a paper sample, linearly 
polarizing it and changing the direction of polarization. The 
plot indicated on polar coordinates takes the form of an 
ellipsoid having its major axis coinciding with the axis of the 
main orientation of the fibers.

Title: Organophilic modified layered-silicic acid adsorbents
IPC: B01J20/10
Filed: 1985-09-12
Abstract: Adsorbents for polar organic compounds can be prepared by reacting 5-80% of an organic ammonium compound with 20-95% of a crystalline alkali metal phyllosilicate belonging to the group comprising phyllosilicates of the formula Me2SixO2x+1.yH2O in which Me denotes an alkali metal ion or a proton, x denotes a number greater than 7, in particular from 7.5 to 23, and y denotes a number smaller than 7x. These organophilic phyllosilicic acids are capable of binding considerable amounts of organic compounds, such as, for example, fats or softeners. They are, therefore, excellently suitable for use as additives for enhancing the washing action in detergents or as a depot for organic compounds.
Patent EP-0177148-A3 (EP)
Title: Power supplies using mosfet devices
IPC: H03K17/0412
Filed: 1985-08-16
Abstract: A power supply for driving multi-electrode semiconduc­
tor power devices such as field effect transistors (FETs) 
including an integrated circuit module providing control 
signals which are coupled to the primary winding of a 
transformer which has two secondary windings. Each secon­
dary winding is coupled to a drive circuit which is coupled to 
an FET. The FETs provide output voltages across an output 
transformer. Each drive circuit includes series-connected 
NPN and PNP transistors, each having a capacitor in its 
current flow circuit so that, as each transistor turns on, 
current flows from the capacitor into the FET to turn it on, the 
capacitor being recharged as the FET conducts. The com­
bination of the transistors and capacitor acts like a power 
supply for the FET.

Patent EP-0195249-A3 (EP)
Title: Procedure for detection of spin and/or slide conditions in vehicles
IPC: B60T8/00
Filed: 1986-02-15
Abstract: The invention proposes to superimpose on the reference setpoint for an electric vehicle drive an identification signal (I), an alternating torque (Mw) being superimposed on the running torque (MB) produced by a motor (9). The reaction of the mechanical system (10) to this excitation is detected, e.g. using a tachogenerator (11), at a suitable point in the mechanical driving system (10), e.g. at the motor shaft (W) or at the driving wheel (R). The tachogenerator (11) emits an alternating voltage (20), from which a measurement signal (S) is obtained by filtering. This signal is compared to the identification signal (I) fed into the driving system, e.g. with the aid of a correlation calculation. By evaluating the result of the correlation calculation, it is possible to establish whether a swerving or sliding condition is present. <IMAGE>
Patent EP-0215367-A3 (EP)
IPC: H01M4/06
Filed: 1986-09-02
Abstract: A means to eliminate the suppression of the closed cir­
cuit voltage of a Li/CF x  battery during the initial part of its dis­
charge is effected by blending an additive CF x  which does not 
show significant voltage suppression with the (bulk) CF x  that is 
normally used in fabricating cathodes for such batteries. 
Blending is used to get a mixture which has substantially mini­
mized voltage suppression and has good capacity.  
     The closed circuit voltage of a Li/CF x  battery during the in­
itial 10% of discharge is known to be lower than the closed cir­
cuit voltage during the later stages. This characteristic ad­
versely impacts applications since the voltage at beginning of 
life is as low as the voltage indicating end of life, complicating 
design of circuitry to indicate end of life.  
     In the diclosure, the material with no significant voltage 
suppression discharges preferentially at the beginning of dis­
charge leading to higher voltage and no suppression. The bulk 
material also discharges to some extent during this early stage 
of discharge. When the small percentage of coke-based CF x  
additive is depleted, the bulk CF x  has discharged to the point 
that it no longer shows voltage suppression.

Title: Smooth, low-friction magnetic recording medium
IPC: G11B5/71
Filed: 1986-05-02
Abstract: Flexible magnetic recording media such as videotapes based on ferromagnetic oxide particles can provide high carrier-to-noise ratios previously available only with metal powder tapes when the recording layer has a high loading (at least 74% by weight) of oxide particles which have a high surface area (at least 40 m2/g) and includes free monobasic fatty acid comprising more than 1.5% by weight of the ferromagnetic oxide particles. The free fatty acid provides a coefficient of friction not exceeding 0.3. A preferred monobasic fatty acid is myristic acid. By incorporating into the binder a lubricant-adsorption inhibitor such as citric acid, a greater proportion of the fatty acid remains free.

Abstract: A two stage valve assembly (14) for a fluid control 
system (10) wherein one stage (48) includes a pressure 
responsive spring centered spool (50) for regulating fluid 
flow between a fluid source (16) and a fluid responsive

Title: Telephone circuit using dc blocked transformer and negative impedance technique
IPC: H04M19/00
Filed: 1989-06-14
Abstract: The invention provides a combination in a SLIC for 
telecommunication applications of ac impedance synthesis, eg. 
raising the impedance of battery feed resistances by feedback 
techniques; in combination with real battery feed resistors and a dc 
blocked transformer. A dc blocked transformer (16) is coupled to line 
current feed resistors (22; 24) and a feedback loop network to synthesize 
the desired input impedance, such that the feedback network incorporates 
both positive and negative feedback. A loop stabilizing resistor is 
used in shunt with the dc blocked transformer secondary to reduce 
gain peaking and phase shift. The transformer is an integral part 
of the feedback loop, and one of the outputs of the solid state 
circuitry are directly connected to the subscriber line, thereby 
eliminating the problem of lightning induced transients, in that the 
output stages of the solid-state operational amplifier circuitry of 
the invention are transformer isolated from the subscriber line, and 
are coupled to the subscriber line through high impedances providing 
high resistance isolation.
