Patent DE-3110919-A1 (DE)
Title: Amplitude and transit time equaliser
Inventor: WEBER HERBERT
IPC: H04B7/005
Filed: 1981-03-20
Abstract: The invention relates to a circuit for amplitude and transit time equalisation of frequency-modulated signals. It comprises two transit time equaliser pairs (LZ1, LZ2) which are activated via a common voltage divider network (STN). A required transit time response can be set by changing the voltage divider ratio. For amplitude equalisation, the signal which is amplitude-modulated by the first transit time equaliser pair (LZ1) is tapped downstream of the latter via a rectifier (DGL) and the signal which is thereby demodulated and whose amplitude can be adjusted is fed to a phase modulator whose output signal is coupled back into the signal path downstream of the second transit time equaliser pair (LZ2). The second transit time equaliser pair (LZ2) and the network connected in parallel with it have equally long transit times. <IMAGE>

Title: Device for striking synchronisation in electronic striking clocks
Inventor: HABERER JENS
IPC: G04G7/00
Filed: 1981-03-31
Abstract: For the purpose of striking synchronisation in electronic striking clocks, the coding of a coding disc which revolves with the wheel works is scanned by means of a phototransistor and by means of light-emitting diodes. The light-emitting diodes are assigned in each case to a coding track, which tracks consist of light-transmitting and light-proof regions. The light-emitting diodes are excited sequentially. If in the process light penetrates via the light-transmitting regions into the interior of the coding disc, which consists of plastic, this fact is detected by the phototransistor, which is arranged on the circumferential surface of the disc.

Title: Developer device for electrophotographic copiers
Inventor: HARTWIG KARL DIPL PHYS
IPC: G03G15/08
Filed: 1982-02-04
Abstract: In a developer device for electrophotographic copiers having a transport roller (4) for circulating a supply (6) of a magnetic two-component developer that is situated in the housing (3) of the developer device, undesired development of dust is avoided by connecting the housing to a suction-air device (13) in the airflow of which a dust filter is inserted. This dust filter is preferably formed by the developer supply (6) which is situated in the housing (3) of the developer device and on whose carrier particles the toner particles that are sucked past by means of the air flow accumulate. This produces a filter which opposes the air flow with only a relatively slight resistance and which requires no cleaning even after operation of arbitrary length, because the captured toner particles automatically pass once again into the developer circuit. <IMAGE>
Patent DE-3205263-A1 (DE)
Title: Two-wheeled vehicle with warning device
Inventor: SCHUERMANN ROSWITHA
IPC: B62J6/20
Filed: 1982-02-15
Abstract: It is proposed, in addition to front and rear light with integrated reflector and lateral reflectors in the wheels, to expand the customary visual warning devices on two-wheeled vehicles by one to four mirrors. The mirrors are to be arranged on the side of the wheels next to the orbit of the reflectors, with the mirror direction forwards and towards the reflector or rearwards and towards the reflector. As a result, it is ensured that when extraneous light falls on the mirror, the reflection path mirror-reflector-mirror triggers a flashing effect in the illumination direction since the reflector moves into a reflection-active position only briefly per revolution of the wheel. In the case of direct illumination of the reflectors, the illumination direction and reflex flashing direction do not coincide since here the reflection path is composed only of the reflector-mirror. By means of the mirrors according to the invention, in combination with the reflectors, two-wheeled vehicles can be protected in an optimum fashion on all sides.

Title: Device for current transfer from a rolled strip passing through an electroplating configuration
Inventor: SCHIMION WERNER
IPC: C25D17/00
Filed: 1982-06-04
Abstract: A device provided for current transfer from a rolled strip passing through an electroplating configuration, having current-carrying rollers bearing on the strip surface and supplied via collecting rings, is to be developed further in such a way as to counteract wear of the shell of the current-carrying rollers caused either mechanically or by the electrolyte, and thus to achieve long useful lives for said rollers. To this end, laterally against each current-carrying roller, a counter roller is guided, and the space, which is located above the touching generatrices of the rollers and which is bounded by the shells thereof, is closed by seals at both ends. A feed line running into this space supplies it with electrolyte, and a series of current-fed anodes, which are arranged behind one another in an axially parallel direction, dips into the electrolyte in such a way that the losses of material of the shells of the current-carrying rollers are replaced electrolytically.

Title: Process for producing colour separations for multicolour printing
Inventor: SCHULTZ URSULA DR ING
IPC: G03F3/08
Filed: 1983-03-28
Abstract: The invention relates to the field of printing technology and in particular to a process which enables ideal production of colour separations for multicolour printing. According to the invention, to take account of a further colour impression range of the variables which affect the printed image while transferring the interrelationships of the trichromatic measuring system to the chromaticity signal measuring system as part of the corrections to take account of the properties of the printing materials, the corrections for taking account of influencing variables having an additive effect is carried out on the chromaticity signals themselves before they are converted into colour density signals, which then yield screen dot signals for colour dimensioning of the printed screen. This method of treating the chromaticity signals makes it possible to dictate colouration and colouration variations from the outset and it also makes it possible to take account of the effect of the surroundings on the impression made by the final printed image so that an increased colour faithfulness of the printed image can be achieved as a result.

Title: Drive for a high-voltage power circuit breaker
Inventor: ZAKOWSKI KRISTOF
IPC: H01H33/16
Filed: 1983-03-31
Abstract: In an electrical high-voltage power circuit breaker having main contacts (1, 2) and having a resistor (5) which can be connected in parallel with the main contacts (1, 2) via resistance contacts (3, 4), the drive has a piston-cylinder arrangement (7) which is supplied from a hydraulic fluid high-pressure source (14), for operating one of these two resistance contacts (3, 4). This drive is intended to be distinguished by a small size in comparison with the power which is to be switched, in conjunction with high reliability, and is nevertheless intended to be capable of being produced cost-effectively. This is achieved in that a further piston-cylinder arrangement (6), to which hydraulic fluid can be applied via a main valve (15), is provided for operating one of the main contacts (1, 2), and in that a control block (25) is connected between the main valve (15) and the piston-cylinder arrangement (7) which is provided for operating the resistance contacts (3, 4), which control block (25) can be controlled as a function of the position of the main (1, 2) and/or resistance contacts (3, 4). Such a circuit breaker is distinguished in that there are no elements which are susceptible to failure, such as jacks, mechanical dampers and couplings. <IMAGE>
