Patent EP-0247358-A3 (EP)
IPC: B01D65/10
Filed: 1987-04-23
Abstract: A copolymeric amphiphilic polyimide precursor having 
  
wherein R¹ is a tetravalent group having at least 2 carbon 
atoms, R² is a bivalent group having at least 2 carbon atoms, 
and R³, R⁴, R⁵ and R⁶ are hydrogen atom or a monovalent 
group having 1 to 30 carbon atoms selected from the group 
consisting of an aliphatic group, an alicyclic group, an aro­
matic group, a group in which an aliphatic group is com­
bined with an aromatic group, or an alicyclic group, and 
their groups substituted by a halogen atom, nitro group, 
amino group, cyano group, methoxy group or acetoxyl 
group, provided that at least one of R³, R⁴, R⁵ and R⁶ is 
neither hydrogen atom nor the above-mentioned group 
which has 1 to 11 carbon atoms; a part of at least one of said 
R¹ and said R² being substituted with a group having a 
valence different therefrom. The precursor of the present 
invention can provide thin films by the LB technique, and by 
ring closure of the obtained LB films, there can be obtained 
ultrathin films having excellent heat resistance, electric 
properties, chemical resistance and mechanical properties, 
and having a thickness of not more than 10,000 Å, and if 
desired, a thickness of 10 to 1,000 Å. Further, according to 
the process of the invention, polyimide thin films having a 
wide range of properties can be easily prepared. When a 
part of the group R² is substituted with a trivalent or tet­
ravalent group, the heat resistance can be improved since 
a ring having better heat resistance than an imide ring is 
formed.

Title: Self-supporting composite building slab, especially false floor slab
IPC: E04C2/26
Filed: 1987-06-12
Abstract: A shallow pan, preferably of tin-coated sheet steel, serves for the production of a self-supporting composite plate, wherein the pan forms the outside wrapper for a filler with high compression resistance, e.g., anhydrite. The pan contains a plurality of punches which provide anchoring with the filler material. To increase the bearing strength of the composite plate, the pan bottom is made up of four intersecting, shallow, bulged-out zones. These zones engage in the middle on a smooth, plate-like elevation and extend each in turn from deep areas along the intersecting symmetry axes of the pan toward the highest areas at each pan corner. The density of the punches in the pan bottom preferably increases from the inside toward the outside.

Patent EP-0240069-A3 (EP)
Title: Device for compensating variations of the driving moment of a one-phase synchronous motor
IPC: H02K21/02
Filed: 1987-03-23
Abstract: The invention relates to a device for improving the stability of rotation of the rotor of a single-phase synchronous motor mounted in an apparatus housing. The motor exhibits an average motor torque on which strong alternating torques are superimposed and which drives a preferably rotating load. The rotating load may be a small domestic appliance such as a citrus-juice extractor, a knife sharpener, or a dry-shaver with rotatary cutters. The device is constructed in such a way that the rotor is influenced by an additional mechanical compensation torque which acts outside the load-transmission path and which counteracts the electro-mechanical alternating torques of the motor for a given, preferably positive, direction of rotation of the rotor, the positive direction of rotation being that direction in which the torque exerted on the rotor by the current becomes initially zero and in which subsequently, shifted through a small angle, the magnetic detent torque, which exists when the stator coils are not energized, also becomes zero. And in this position a stable rest position of the rotor is provided and the opposite direction of rotation is blocked. Blocking is effected by means of a unidirectional device.

Patent EP-0307068-A3 (EP)
Title: Long time constant integrating circuit
IPC: G06G7/186
Filed: 1988-04-15
Abstract: A method and apparatus for performing 
integration using a circuit capable of integrating an 
input signal over a wide linear dynamic range. The 
circuit modulates the input signal with a biphase 
signal having positive and negative phases. The 
modulated signal is then provided to an integrator. 
The integrator operates continuously within its linear 
range without needing charge dumping because the 
amplitude of the modulated signal is less than the 
amplitude required to saturate the integrator. Each 
interval of the integrated signal corresponding to 
positive and negative phases of the biphase signal is 
then partitioned into intervals corresponding to the 
positive phases and intervals corresponding to the 
negative phases by two track and hold circuits with 
alternating tracking and holding periods. The signal 
intervals corresponding to the negative phase of the 
biphase signal are subtracted from the intervals 
corresponding to the postive phases by a differential 
amplifier. These subtracted intervals are then added 
together by a sample and hold circuit joined with a 
summing circuit to produce the integrated signal 
corresponding to the linear integration of the input 
 
 
signal. The circuit is thus the mathematical 
equivalent of dividing the desired period of 
integration into a finite number of intervals, 
integrating each interval over that subdivided portion 
of the desired integration period, then adding the 
integrals of the intervals which equals the integral 
over the desired integration period. The frequency of 
the biphase signal can be adjusted so that integration 
of the subdivided portions of the desired period of 
integration requires capacitors sizes capables of being 
incorporated onto an integrated circuit.

Abstract: Disclosed is a method for separating initially non-magnetized ferromagnetic material. The material has a distribution of magnetic parameters, and is separated into a first fraction having relatively high magnetic parameters and a second fraction having relatively low magnetic parameters. The method comprises applying a magnetic field to the materials, the magnetic field being high enough to magnetize the low magnetic parameter fraction, but low enough to avoid substantial magnetization of the high parameter fraction. Thereafter the fractions of material are magnetically separated.
