Title: Telephone exchange, peripherals to common processor, coupling - uses intermediate FIFO buffer store to accommodate scan cycle delay
Inventor: BURKART PETER
IPC: H04Q3/545
Filed: 1980-05-02
Abstract: Address and data coupling of the line terminating units in a telephone exchange with the central processor in that exchange is accomplished by using FIFO intermediate storage so that information can be read from central processor to terminating units, and vice versa, using the line scan cycle. The terminating units (AO) are scanned using a cycle which has time slot allocations for reading command information out of the intermediate storage (FB of AS) where it has been lodged after being output from the central processor (ZS) onto the data bus (DB) with an address for the appropriate terminating unit (AO). The terminating unit (AO) are in peripherals of the exchange and each has a peripheral control (PST) incorporating a peripheral clocking and protocol control processor (STP). Each terminating unit (AO) in the exchange operates on the basis of having time slot allocations for reading out the information in the FIFO working store (AS) which has been lodged there by the exchange central processor (ZS). The intermediate store (AS) ensures that each peripheral decentralised terminating unit (AO) is ready to receive information from the exchange central processor (ZS).

Title: Sprinkler adjustable to different sprinkling areas and water pressures
Inventor: SCHANZ FRIEDRICH
IPC: B05B1/16
Filed: 1981-05-14
Abstract: The sprinkler has a tube-like nozzle (fan nozzle 4) pivotable to and fro about a horizontal axis (C-D) and having nozzle bores (5-20) arranged at different inclinations along a generatrix. Arranged in the fan nozzle (4) is a round-body slide (21) which is axially adjustable via the nozzle bores (5-20) and which bears sealingly with its circumference against the inner cylindrical surface of the fan nozzle (4). The round-body slide is intended for inactivating some of the nozzle bores so as to match the particular supply of water, without the water jets from the remaining nozzle bores being appreciably weakened. It is thereby possible in a simple way, by reducing the water consumption, to bring about an increase in pressure in the line and therefore an optimum performance. <IMAGE>

Title: Electrophotographic two-colour copier
Inventor: MATSUMOTO FUYUHIKO
IPC: G03G15/09
Filed: 1981-05-15
Abstract: An electrophotographic two-colour copier has a nonmagnetic sleeve for feeding magnetic toner to latent, electrostatic images on a photoconductor and for developing the images in one or both development sections for the two colours. It is possible by means of the so-called counter-electrode effect to obtain two-colour copies in which the so-called edge effect is completely or substantially eliminated. In different embodiments, a number of ribs and grooves are constructed on the external circumferential surface of the nonmagnetic sleeve. The crest faces of these ribs reduce the effective spacing between the nonmagnetic sleeve and the surface of the photoconductor. This reduction in the spacing is advantageous with reference to increasing the counter-electrode effect. At the same time, the grooves form devices for conveying an adequate amount of toner past the doctor blade in the developer device, whereas so far the conveyance of an adequate amount of toner past a doctor blade has represented a difficulty because the previously mentioned spacing from the nonmagnetic sleeve to the photoconductor was shortened.

Title: Folding-wing door
Inventor: FISCHER WOLFGANG
IPC: E05F15/605
Filed: 1981-06-10
Abstract: The invention relates to a folding-wing door with a paired arrangement of the folding wings. Located between every two folding wings is a bending point, in the region of which a drive is arranged. The latter is to cause a pivoting of 90 DEG  of each door wing, so that the folding-wing door as a whole can execute a pivoting movement of 180 DEG . Whilst it is known to cause the drive by means of two piston/cylinder arrangements, according to the invention the drive is designed so that a bearing block having two oppositely drivable rotary levers is arranged at the bending point at the region between two door wings, and that the free ends of the rotary levers are each connected in an articulated manner to a door wing via an adjusting rod. This avoids, inter alia, additional measures for damping the adjusting movement in the end regions.
Patent DE-3128256-A1 (DE)
Inventor: ZIERHUT HERMANN DIPL ING
IPC: G08B29/00
Filed: 1981-07-17
Abstract: A motion detector responsive to infrared radiation, e.g. for use in burglar-alarm installations, comprises a pair of juxtaposed sensors monitoring adjacent fields of view of a space to be surveyed, giving rise to output signals of opposite polarity upon detecting a disturbance in their respective fields. These output signals are fed to an evaluator comprising two complementary transistors with interconnected emitters and interconnected bases whose junctions are separated by a resistive branch of an RC network, the emitter junction receiving the output signals while the base junction is capacitively coupled to ground or some other point of fixed potential. The collectors of these transistors, energized via respective resistors from opposite terminals of a d-c supply, are connected to respective timers working into a common AND gate which triggers an alarm when an alternation of output signals from the two sensors renders the timers conductive for overlapping periods.
