Title: Attachment of hardened strips for machine bed - uses larger clearance holes and spacer washers under screw heads
Inventor: JANOWIAK BRUNO
IPC: F16B5/02
Filed: 1978-09-08
Abstract: The method of securing hardened steel strips (11) particularly slide strips to the bed of a machine (12) uses bolts (14) which screw into holes (13) tapped in the bed, and clearance holes (15) through the strips. In order to compensate for inaccuracy in positioning any of the holes, the clearance holes are made larger than normal, and spacer washers (20) are fitted under the bolt heads. These washers then rest on the shoulders inside the clearance holes. In an alternative design, where support members in the bed of the machine are sufficiently thin, the holes can be tapped on the strips, and the clearance holes made in the support members. It is then necessary to form only a shallow counterbore for the washers.

Title: Telephone instrument circuit with amplifiers - uses balance network and biassing to control gain and transmission direction
Inventor: LUEHMANN HANS-GUENTHER DIPL IN
IPC: H04M1/58
Filed: 1979-02-15
Abstract: The circuit is for a telephone instrument using integrated circuit (IC) amps for transmit and receive amplification and also has high voltage protection. The transmitter (M) is asymmetrically connected to the input of an operational amplifier (OP1), and the amplifier output is connected to a line balancing network (C2, R9, R10, and then one speech wire (SA) to the exchange line (SA, SB). The output of the transmit amplifier (OP1) is also connected to the non-inverting input of the receive amp (OP2) with the receiver (F) on its output. The line balancing network (C2, R9, R10) has a resistance range between unity and 0.3 so that send amplification can be realised with local instrument side tone attenuation due to potentials applied to switching transistors (T1, T2) and diodes (G1) when the biassing on the transmission amplifier is altered by output and feedback through the potential divider and diode chain (R4, R5, R6, R7, R8, C1, G2, G3). A transistor (T2) on the receive amplifier (OP2) output serves as a constant current regulator.

Title: Relay controlled master lock for alarm system - cannot be turned if fault or alarm condition exists and relay is operated by short-circuit proof amplifier
Inventor: BEIGEL HELMUT
IPC: G08B13/00
Filed: 1979-04-14
Abstract: The master lock of an alarm system, i.e. the last one to be locked when securing a building, sets the system to 'alert' but can only be turned if a locking relay is operated. The relay is operated, by a short-circuit proof amplifier, for a predetermined time when a 'set' instruction is given, but only if no fault or alarm indications are being given. Once these conditions have been met, a signal is fed back to a gate circuit, which blocks any subsequent faults or alarms from influencing the setting procedure. The 'alert' condition is reported to the central monitoring station at the end of the relay operating time.
