Title: Bending device for sheet-metal straps
Inventor: STAUDT EIKE DIPL ING
IPC: B21D11/10
Filed: 1982-06-03
Abstract: A bending device for sheet-metal straps (3) on rails (1), which bending device can be carried and operated by one hand and in which a linkage provided with a handle (5) carries a punch part (7). Here, it is desirable for the bending device not only to be simpler to operate in terms of strength and skill but also to have improved guidance of the punch part during the bending downwards movement. This is achieved by a lever arm (4) connected to the handle (5) being provided at an end on which the pivot spindle (8) is provided, and by being connected to an abutment (6) and carrying the punch part (7) at a distance from the pivot spindle, and by the abutment being a strut piece (6) essentially reaching beyond the rail width. On account of the lever arm, the power required to bend the strap is considerably reduced. The strut-piece abutment reaches behind the rail and is guided on the rail. <IMAGE>

Title: Torque and mass compensation for a rolling mill
Inventor: REHAG KLAUS
IPC: B21B21/00
Filed: 1982-06-07
Abstract: The present invention relates to the drive for a cold pilger rolling mill in which the roll stand is connected via a connecting rod to a crank drive which is connected to vertically guided compensation weights, which can be moved up and down, and is provided with revolving mass-compensation weights. Since full compensation of the mass moments and torque is not guaranteed in known drives of this type, the object of the invention is to provide an improved drive for cold pilger rolling mills. It is proposed to design the crank rod as a double lever (Z) which is mounted at its centre on the crank drive and the ends (C, D) of which are in each case guided on a rectilinear, horizontal (X) and vertical (Y) path crossing the axis of rotation of the crank drive and are connected on the one hand to the connecting rod of the roll stand and on the other hand to the compensation mass (G). <IMAGE>

Title: Method for preventing the setting up of calls which may not, or cannot, be initiated in telecommunications exchanges, in particular telephone exchanges
Inventor: KRETZ HANS-JOACHIM ING GRAD
IPC: H04Q3/62
Filed: 1982-08-09
Abstract: The method for preventing the setting up of calls, which may not or cannot be initiated, in telecommunications exchanges, in particular telephone exchanges, provides that exchanges which are interconnected via tie lines inform one another using special identification codes when an incoming call cannot be initiated under certain circumstances or is not permitted in unrestricted fashion. The result of this is that all other connections can be set up freely over a plurality of exchanges, either directly or by way of call-back and transfer. The special identification codes which may be required in order to prevent the setting up of calls which may not or cannot be initiated are transmitted via the connection line to the nearest exchange immediately after the seizure criterion in the form of digits or combinations of digits identical to the dialling information. In order to distinguish the special identification code from the dialling information, an end signal which is distinguishable from the dialling information is provided which is transmitted at the end of the special identification code immediately before the dialling information is transmitted.

Patent DE-3242735-A1 (DE)
Title: Electronic multitone gong
Inventor: LIHL GUENTER DIPL ING
IPC: B06B1/02
Filed: 1982-11-19
Abstract: Electronic multitone gongs with a start circuit which can be triggered by a bell button of a house bell system, a tone generator and a controlling clock generator and an AF amplifier feeding a small loudspeaker require a power supply which is usually represented by a dry cell battery and in some cases also by a separate power supply unit. To be able to operate the electronic multitone gong also without separate battery or mains installations, the connection to the bell button is connected to a voltage-multiplier rectifier circuit having a high storage capability which takes over the power supply to the gong. In this arrangement, the start circuit is constructed in such a manner that it triggers the gong as soon as the voltage present after a rectifier circuit exceeds a predetermined voltage value. A voltage monitoring stage can determine when the dropping voltage drops below a minimum value required for operating the gong and then switch the gong off or over, continuously increasingly attenuate the AF amplifier and switch the arrangement back to its original switching state.

Patent DE-3325249-A1 (DE)
Title: Track circuit receiver
Inventor: GSCHWIND HANS W DR ING
IPC: B61L1/18
Filed: 1983-07-13
Abstract: A track circuit receiver is specified which apart from a useful signal originating from the track circuit transmitter separately detects and evaluates the noise level and prevents a track release signal when the noise level is too high. In this case, noise signals are also detected which have exactly the same frequency and the same phase angle as the useful signal. The track circuit receiver contains on the input side two filters (F1, F2) of different bandwidth which operate as synchronous detectors. The output signal of the narrow-band filter is fed to an evaluation circuit (AW) and, when it exceeds a prescribed threshold, causes the output of a track release signal to a track release signalling line (GF). However, this output is blocked when a voltage which is obtained in a comparison circuit (VG) by comparing the two filter output signals and reproduces the noise level exceeds a prescribed fraction of the output signal of the narrow-band filter. <IMAGE>

Title: Special tetrad adder in BCD 8421 code
Inventor: MERKLE PAUL
IPC: G06F7/494
Filed: 1983-08-05
Abstract: The tetrad adder according to the inventive subject matter consists of a dual tetrad adder (main circuit 7) and a correction circuit 18 for subtracting the number 6 (LHHL), which is acted upon by the negated carry output y or a negated branch of this carry output. One of the two summands is input in BCD 6 code. If no carry comes about in the main circuit 7, H potential is applied to the correction circuit 18 via the line c, and thus the number 6 (LHHL) is subtracted from the result number of the main circuit 7, and thus the result number of the main circuit 7 is converted from BCD 6 to BCD 0. If a carry comes about in the main circuit 7, the result number already occurs in the main circuit 7 in BCD 0 code. In this case, the line c has L potential, and thus only the number 0 (LLLL) is subtracted from the result number of the main circuit 7. Consequently, the addition result number occurs in both cases in BCD 0 code. <IMAGE>

Title: Climbing raisable scaffold with cable drive
Inventor: STEFFEN BURKHARD DIPL ING
IPC: B66F11/04
Filed: 1983-12-13
Abstract: For operating a raisable scaffold independently of the construction concerned, the bridge girder hangs by means of cables on scaffold supports. The drive in this case takes place by means of double capstans. The raisable scaffold is progressively built up or taken down without external aids by means of its own drive and a climbing mechanism. The raisable scaffold can be built up with one, two or more scaffold supports, and at the same time one or more bridge girders can be operated on the scaffold supports. Due to the fact that the supporting part of the bridge girder is on the side opposite the building, fixedly installable, horizontal supporting devices are possible between building and scaffold support.
