Patent EP-0200568-A3 (EP)
IPC: C04B35/83
Filed: 1986-05-02
Abstract: A porous, permeable substrate has a first coefficient of 
thermal expansion. The substrate may be formed from a 
plurality of discrete elements defining interstices. A matrix is 
disposed on the substrate without any chemical bond to the 
substrate. The matrix has a second coefficient of thermal 
expansion different from the first coefficient of thermal 
expansion and is free to move relative to the substrate with 
changes in temperature. The matrix may constitute a 
non-stoichiometric compound formed from a metal and a 
material providing negatively charged ions. The excess from 
the stoichiometric ratio in the amount of the metal or the 
material providing the negatively charged ion controls the 
properties of the matrix. The relative amount of the excess of 
the metal or the material providing the negatively charged 
ions from the stoichiometric ratio may be varied at different 
thicknesses of the matrix to vary the properties of the matrix 
at the different thicknesses. The matrix may have microsco­
pic cracks in its periphery. A porous, impermeable coating 
may be disposed on the matrix and may be provided with 
substantially the second coefficient of thermal expansion. 
The impermeable coating covers the microscopic cracks and 
is instrumental in preventing the matrix from oxidizing. A 
porous, impermeable coating may also be disposed between 
the substrate and the matrix and may be provided with 
substantially the second coefficient of thermal expansion. 
This coating prevents the substrate from oxidizing. The 
different coatings or layers may be formed by a continuous 
process or by cyclic or pulsing techniques.
Patent EP-0202066-A3 (EP)
Title: Filter
IPC: B01D46/24
Filed: 1986-05-06
Abstract: The invention provides a plurality of filter elements 7 disposed on a mounting plate 16. Negative pressure is induced to the exterior of the filter elements 7 thereby drawing dust-laden air into their hollow interiors. The hollow interiors have a smooth low friction surface and hence, when the negative pressure is switched off, dust formed within the interior of the filter element falls under its own weight into a dust receptacle 3. The rigid or semi-rigid filter elements 7 are adapted to be agitated with the negative pressure switched off so as to dislodge any dust particles remaining therein.
Patent EP-0228771-A3 (EP)
Title: Data transmission system
IPC: H04L7/08
Filed: 1986-10-08
Abstract: In a data transmission system data is sent, after suitable conversion, as a ternary analogue type signal. Using two-wire twisted pairs and hybrids, echo cancellation and feedback equalization are needed. Synchronization between the two ends, e.g. of a 144 Kb/sec. subscriber's loop, is maintained by a low amplitude pilot tone sent with the data, which is detected at the same time as the data is detected. Detection and elimination of this pilot tone use coefficient generation circuitry similar to those used in the equalizer and echo canceller. To reduce the effect of time phase steps on the system performance, in addition to the transmission of a specific zero valued frame synchronization word which immediately precedes the phase step, the incoming synchronization word is also aligned to this time so that the value of a symbol as received can be predicted, as for a synchronization word, the predicted value is given preference if there is a difference between that symbol's value as received and its predicted value. In addition, the location of the high-pass filters used in the system are specified, alternative methods of bit timing control are specified and advantageous realizations of the canceller and equalizer using tap interpolation are disclosed.

Patent EP-0223728-A3 (EP)
IPC: F02M51/00
Filed: 1986-09-22
Abstract: An electromagnetically-actuated fuel injector of 
the type having a spring-biased flat armature (40) and a 
ball valve element (30) is provided with an improved 
arrangement for preventing wobble or flutter of the 
armature (40), particularly during operation. The 
substantially-circular armature (40) includes a portion 
contoured to define a pivot axis for the armature (40) as 
it engages a stationary part (48B) of the injector. This 
pivot axis is conveniently provided by a chordal edge 
(70) on the armature (40). This arrangement aids in re­
ducing wobble by the armature (40) and is further en­
hanced by concentrating the spring force on the armature 
(40) remote from the pivot axis. This concentrated spring 
force is obtained by providing a spring seat on the 
armature (40) which is inclined such that the spring (54) 
experiences greater compression where the spring force is 
required.

Title: A method and an arrangement for the finishing of an opening arrangement on a packing container
IPC: B65B61/18
Filed: 1987-04-09
Abstract: In the manufacture of aseptic packing containers from weblike laminate material the material usually is brought into contact with a liquid sterilizing agent which, after a certain treatment period, is removed again. In order to avoid any accumulation of residues of sterilizing agent behind lugs, opening strips or the like a method and an arrangement for finishing an opening arrangement (2) on a packing container (1) are proposed, according to which an external gripping element (3) is placed over the opening region (4) only after the packing container (1) has been filled with the desired contents and has been closed. This is achieved with the help of a sealing unit (9) with vacuum device (10) and a gas-permeable striplike gripping element (3).

Patent EP-0253345-A3 (EP)
Title: Inductive power coupling with constant voltage output
IPC: B60L5/00
Filed: 1987-07-13
Abstract: A constant voltage inductive power coupling for magnetically transferring electrical power from a power source through an air gap to a load comprising a first electromagnetic inductor connected to a power source to generate a shaped alternating magnetic field, a said inductor with a saturable core separated by an air gap from the first inductor and magnetically coupled thereto to receive the shaped magnetic field, the core being responsive to the field to enter a state of magnetic saturation. A coil is electromagnetically coupled to the saturable core and has output leads connected to the load. The magnetic field induced by the first inductor to the second inductor causes voltage in the coil, whose magnitude is determined by the amount of magnetic flux in the core. The saturable core is responsive to any change in input voltage to magnetically counteract such change so as to maintain the core in its state of saturation thereby tending to keep the output voltage constant. The invention is particularly useful in battery charging circuits or for other applications where the voltage required must be kept at a constant level.

Patent EP-0268043-A3 (EP)
Title: Dc power supply circuit for fluorescent lamps
IPC: H05B41/392
Filed: 1987-09-25
Abstract: The DC power supply circuit has an isolating transformer (13'), whose inductance (16) is alternately charged via an electronic switch (T2) and discharged via a diode (17) onto a capacitor (18). The initial voltage (UA) of the isolating transformer is continuously monitored. If a threshold value is exceeded, the switch (T2) located in an input line (11) of the isolating transformer is switched to the off state. The off state is terminated as soon as the initial voltage drops below the threshold value again. The DC power supply circuit allows loads which require a specific DC voltage to be connected to different supply voltages without any changeover switching being required. The circuit provides good safety against overvoltage originating from the mains. It is self-monitoring and protects the connected load.
