Title: Reception and decoder circuit for slave clock - has seconds pulse generator synchronised with received signal
Inventor: HAAG EUGEN
IPC: G04R20/10
Filed: 1977-01-14
Abstract: The reception and decoder circuit for a slave clock has a seconds pulse generator supplying 60 seconds pulses each minute, which are synchronised with the received signal. The minutes signal supplied by the reception circuit is used to reset the counter circuit of the internal seconds pulse generator used for frequency division. Pref., if the received signal fails, the slave clock is automatically switched to autonomous operation. The quartz oscillator used for the seconds pulse generator pref. also provides the IF signal for the heterodyne reception circuit.

Filed: 1977-02-04
Abstract: A coal mining machine has a rotary drum cutter (18) mounted on a horizontal axis, and which is mounted on an arm (12) which can swing about a vertical axis (16). This enables the drum to be used continuously, travelling in either direction.

Title: Scan holding circuit for phase discriminator - has generating circuit separated from holding capacitor by three switches reducing interference to min.
Inventor: KUBETZKO DIETRICH
IPC: G11C27/02
Filed: 1977-04-23
Abstract: The circuit generates a saw-tooth voltage with phase and period equal to those of a reference voltage. The sawtooth generator can be connected to a holding capacitor through two switches connected in series. They are made conducting or blocked depending on the phase difference between the reference voltage and a further voltage of the same frequency. The capacitor is followed by an amplifier with high input impedance, pref. a voltage follower. In order to reduce interferences from the reference voltage (S2) to the scanning holding circuit (3) output signal (Um) the two switches (K1, K2) are always switched together. A third switch (K3) is controlled, by a switching signal (S2) complementary to the switching signal (S2) so that the holding capacitor (CH) is to the highest degree screened from the a.c. voltage component passing through the blocked switch (K1). In order to shorten transient processes capacitance of the capacitor (CH) is small in comparison with that of capacitor (C1) generating the saw-tooth voltage.

Title: Measuring instrument spindle bearing - has spindle point and bearing cup tilting under torque from arm through spring
Inventor: BRUCHER EGON ING GRAD
IPC: F16C27/08
Filed: 1977-05-02
Abstract: The point-type bearing for a measuring instrument has a bearing cup of hollow conical section in which the point of a spindle fits, and in turn supported by a mounting surface. Acceleration forces resulting from shocks and vibrations are allowed for by deflection of cup or point, which is limited by a spring. To limit the forces transmitted to the mounting surface, the spring (4) acts on the supporting surface via an arm at right angles to the spindle (7) axis, or to an extension of the latter. The point (8) of the spindle (7) and the bearing cup (1) can tilt in relation to this arm under the effect of torque transmitted by the arm through the spring and into the supporting surface.

Title: Rotary magnet and plate tumbler cylinder lock - has eccentric cranks in magnets activating tumblers for extra mounting space
Inventor: HEIMANN GEORG DR
IPC: E05B47/00
Filed: 1978-04-24

The plate tumblers (5) are activated via cracks (4) set eccentrically in the rotary magnets (3), and move in a plane parallel to the magnet surfaces. This arrangement provides space for faultless rotary magnet mounting (8) with cross magnetisation. Drawing the key magnets results in secured alignment of the rotary lock magnets and thus secure bolting of cylinder core (2) against case (1). The plate tumblers preferably have no direct mechanically rigid link with the rotary magnets, so that no forces can be transferred to the latter when the lock is bolted.

Title: Passive electro-optical display cell - has two glass plates containing space filled with layer of non-active material
Inventor: CHARLES JOHN
IPC: G02F1/139
Filed: 1978-09-21
Abstract: The passive electrooptical display cell layer (8) is made of a material which does not react brightly to the electrical field effects. The layer is interrupted near the display regions which are filled by an active constituent (9). At rest, this constituent has a dark appearance so that, when an electrical field is applied to the regions not supposed to be visible, they become bright and mingle with the rest of the display region taken up by the non-active material. Thus, only the non-activated regions remain visible. The active constituent is made of a mixture of a nemat ic liquid crystal and two coloured molecules.
