Title: Pigment forming symbols removed from inscribing surface - by adhesive strip picking up pigment mixed with adhesion inhibitor
Inventor: KOHLE ULRICH
IPC: C09D11/16
Filed: 1978-12-20
Abstract: A modification to a process in which symbols are inscribed on the treated or impregnated surface of a film or paper, by means of a pigment mixed with a solvent for an adhesive to which an adhesion inhibitor has been added, facilitates the removal of the symbols. The inscription formed by the pigment is removed completely from its underlay by means of a single-side, adhesive, transparent film, to which it adheres as a mirror image. The underlay can thus be cleaned completely, and since the symbols can be read through the adhesive film, this can be applied to a new underlay where it is protected against mechanical damage.

Title: Crucibleless zone melting generator - cut off by sparkover causing capacitor discharge and relay response
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1979-07-18
Abstract: A high-frequency generator which is used for the crucible-less zone melting of silicon is automatically cut off when spark-overs occur near the induction heating coil. The rectified high-frequency voltage of the coil charges a capacitor through a resistor and/or a diode and a drop, induces by a spark-over discharges the capacitor. The discharge current flows preferably through a light-emitting diode and the light emitted by it acts on a phototransistor to energise a relay and cut off the h.f. generator. This is functionally more reliable than the conventional differentiating systems because it does not respond to mains voltage fluctuations.

Title: Signal send-receive circuit for telephone exchanges - has two adjustable thresholds for preventing receiver processing below-threshold receiving call signals
Inventor: KOENIG JUSTUS
IPC: H04Q1/442
Filed: 1980-03-27
Abstract: The appts. includes a transformer (U1) coupled telephone lines (a1,b1,a2,b2, with high frequency chokes (D) linked to an a-c generator comprising an operational amplifier (P1) and an a-c receiver with another operational amplifier (P2) via one and the same capacitor (C1). A control device (Z) applies control voltage to both the a-c sending circuit and to an a-c receiving sensitizing circuit. When the sending control voltage (Z1) is grounded a transistor (T1) enables the diode network (E1 to E4) to become conductive and to allow the transformer (U2) to transmit 25 cycle energy to the capacitors (C1,C2). These form not only a parallel resonance condition with the transformer secondary (U2,II) but also a series resonance condition with the choke coils (D,I,II). The a-c receiving amplifier (P2) is insensitive to these voltages in that the control voltage (ZZ) is set to produce a blocking voltage via feedback resistor (R) to the diodes (G1,G2). The variable voltage divider resistors (R8,R9) can be set so as to determine the minimum a-c signal level below which the receiver remains non-responsive to the pulsing rectified voltages applied at terminals (X,Y) of the operational amplifier (P2) thus producing no a-c output across resistor load (R7).

Title: Electroacoustic transducer with high coercivity magnet - has fixed coil assembly with magnet fixed directly to membrane
Inventor: WARNING PAUL-FRIEDRICH ING GRA
IPC: H04R11/02
Filed: 1980-07-21
Abstract: The electro-acoustic transducer is constructed with a flat, axially moving magnet, whose two poles can be utilised simply, and in spite of having an ironless coil assembly and flat field line pattern, can be highly efficient. The distance of the magnet from the membrane cone can be small if the magnetic flux from both poles is used in a coil assembly consisting of two coils. The height of the round magnet is approximately half its diameter, plus or minus 20 per cent, and highly coercive magnets with this height to diameter ratio give lines of force with a particularly favourable characteristic. The distance between coils (3,4) can be determined by a support plate (5), the flat magnet (2) being fixed to the membrane (1) with an adhesive and so arranged that each pole moves in its respective coil (3,4). This construction results in a transducer which is highly efficient and requires fewer components and materials in its manufacture.
