Title: Method for regulating the steam output of a boiler plant for utilising waste heat and a boiler plant for utilising waste heat for carrying out this method
Inventor: SMOLNIK ALEKSEJ JUREVIC
IPC: F22B35/00
Filed: 1984-02-28
Abstract: The invention relates to marine and stationary power plants having a plurality of waste-heat boilers with forced circulation which are heated by individual sources having a gas throughput and gas temperature which varies with time. The method for regulating the steam output of a boiler plant which contains a plurality of waste-heat boilers (1, 2, 3) with forced circulation consists in that the temperature of the gases is monitored upstream of the connected waste-heat boilers (1, 2, 3), the temperature values obtained are compared with one another and the recirculating water of the waste-heat boilers (1, 2, 3) is cooled from the temperature of the feed water to a temperature which is the minimum permissible temperature for the conditions of low-temperature corrosion, the starting point being in each case the boiler which is heated using gases at the lowest temperature. The boiler plant for carrying out the method contains at least two waste-heat boilers (1, 2, 3) with forced circulation, a steam separator (10), a feed-water pipeline (11) and means for measuring the temperature of the gases and of the circulating water at the inlet into the waste-heat boilers (1, 2, 3). Provided between the recirculating pump (24) and the heating surfaces of each of the waste-heat boilers (1, 2, 3) are heat exchangers (15, 16, 17) which are likewise connected to the feed-water pipeline (11). The invention can be applied in boiler plants in motor ships and gas-turbine ships, the converters of smelting plants and chemical factories, as well as power stations. <IMAGE>

Patent DE-3417760-A1 (DE)
Title: Agricultural implement carrier for row and bed cultivations
Inventor: MUELLER LUDWIG
IPC: B62D49/06
Filed: 1984-05-12
Abstract: The invention constitutes a continuously self-driven implement carrier for agriculture and horticulture with all low and/or high row and double-bed cultivations. By a low and/or high special design by means of crawler units, the wheel pressure over the length of the wheel tracks is reduced, so that it is possible to travel in a pressure-reducing manner even in closely arranged cultivations. The rear driven crawler unit and those of the front axle are steerable and are therefore extremely manoeuvrable and can swing longitudinally and laterally, so that, by means of a hydraulic slope compensation, a snug and secure bearing of the crawler units on the ground is achieved. The front axle and mounting axle of the low version and the supporting and carrying axle of the version for high cultivations are telescopic and variable from 2 m to 4 m in a continuously hydraulic manner or manually. It has been possible to provide five mounting and two superstructure spaces as a result of the design. Thus, a row-type chopping cutter has been extended to form a vegetable leaf beater, a gas apparatus has been incorporated in the implement system, and it has been possible to extend the burning-off implement by means of protective tunnels.

Patent DE-3421342-A1 (DE)
Title: Process for the simplified work-up of solutions containing resinous constituents
Inventor: KARGOL BERND
IPC: B01D1/00
Filed: 1984-06-08
Abstract: The invention relates to a process for the distillative work-up of solutions containing resinous constituents. The solutions may comprise solvents having a boiling range of 40-200 DEG C - individually or in mixtures - and resinous constituents, the latter essentially polymer-based. For work-up, a distillation plant is used whose evaporator still can accommodate readily interchangeable inserts developed specifically for this purpose. These inserts are made of special paper or plastic film. These inserts ensure, inter alia, that the heat-transfer surface of the evaporator still does not become encrusted, the resinous residues can be removed very substantially by distillation, and the environmental pollution during changeover remains within permissible limits. The advantage of the invention compared with conventional processes is demonstrated on solutions of photoresists and methylene chloride or 1,1,1-trichloroethane.
Patent DE-3423688-A1 (DE)
Title: Expansion rivet arrangement
Inventor: WOLLAR BURNELL J
IPC: F16B19/10
Filed: 1984-06-27
Abstract: An expansion rivet arrangement has an expandable hollow plastic rivet and a plastic driving pin. The rivet has a head and shank which can be inserted into aligned openings in the workpieces which are to be connected. The driving pin has a head and a shank which can be inserted into the rivet hole and is created and designed such that it can be pulled axially into the rivet hole with the aid of a workpiece which results in the pin head engaging with the insertion end of the rivet shank and causes an outwardly directed expansion of the rivet shank wall. In addition, the excess projecting end of the pin shank is caused to break off at a breaking-off depression which is constructed in the pin shank. The pin shank has a groove in the vicinity of its head end which engages with a hole section of reduced diameter in the rivet in order to hold the pin and the rivet together temporarily before use. The pin shank also has ribs or grooves which engage with a further hole section of reduced diameter in the rivet when the pin is completely inserted in order to hold the pin and the rivet together permanently. This other hole section with a reduced diameter is provided with ribs or grooves in order to reinforce the engagement with the ribs or grooves.

Title: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems with subscriber stations which can be connected via subscriber connection circuits to dial signal receiving devices
Inventor: WEIGELT HEINZ
IPC: H04M15/10
Filed: 1984-07-03
Abstract: Sampling of the connection-specific dial pulse strings and charge metering pulses on a subscriber connection circuit to produce itemised call statements. The dial pulses are transmitted in connection-specific fashion from a contact of the dial signal reception relay in the pulse group selector via a series resistor and the meter wire back to the subscriber connection circuit concerned. The charge pulse meter remains unaffected by these dial pulses due to the action of the series resistor. A sampling device connected to the subscriber connection circuit receives these dial pulses and charge metering pulses and differentiates and records them. <IMAGE>

Title: Winding arrangement for transformers and inductors with windings cast in casting resin
Inventor: BENDEL WOLFGANG
IPC: H01F27/32
Filed: 1984-08-13
Abstract: In such winding arrangements, prefabricated supporting means, serving for spacing and fixing the windings in a casting mould, usually remain behind as part of the insulation in the winding block. According to the invention, porous mould parts (2), each of which is itself baked together from granular, dust-free particles of inorganic material superficially wetted with a synthetic resin, serve as supporting means, and the same synthetic resin as is used for wetting the granular particles is used as the casting resin, and in the operational winding block (6) the pores in the mould parts (2) are completely filled with the casting resin. The use of these porous mould parts as supporting means in moulds for encapsulating transformer windings with casting resin is advantageous in particular when they operate in transformers with rated voltages in excess of 10 kV. The particular advantage of these porous mould parts is the electrically and mechanically high-grade bond which can be achieved within the winding block (6). <IMAGE>

Title: Device for measuring the level of contamination of a sieve or filter
Inventor: MUELLER MANFRED DIPL ING
IPC: B01D35/143
Filed: 1985-02-26
Abstract: The invention relates to a device for measuring the level of contamination of a sieve or of a filter in a liquid flow, especially in the cooling-water flow of a condenser. In order to increase the sensitivity irrespective of the pressure prevailing within the liquid, the resultant force on an eccentrically supported flap, resulting from the different pressures upstream and downstream of the loaded surface is passed out of the liquid flow as a torque and is measured as force. The device requires no initial blocking since it is insensitive to disturbances and contamination. All the sensitive parts are located outside the liquid, so that they are accessible for servicing and repair. In addition, a functional test can be carried out very easily. The device according to the invention replaces a conventional pressure-difference measurement. <IMAGE>

Title: Minimal MIDI interface computer system, Version 1.2
Inventor: GENSKE ROLAND
IPC: G06F3/16
Filed: 1985-08-29
Abstract: The invention is based on the fact that, since 1983, digitally controlled musical instruments have been increasingly fitted with MIDI interfaces, offering the possibility of communication with or control of this type of musical instrument from a home computer or personal computer. However, despite the enormous versatility of these devices, this facility is not used by most musicians, since the cost of a computer system with software is too high and the system components are often not portable. This invention solves the problem with a design for a minimum computer system. The manufacturing costs are low, the software is easy to use, and the system is small, economical, robust and easy to transport for the musician. The system is based on a Z-80 microprocessor, having a user interface with 12 keys and display LEDs and with 4 kilobytes of programmable operating memory. Further characterising features include an exchangeable, battery-backed-up static RAM memory card with a capacity of 24 kilobytes and a new type of on/off logic to improve operational reliability and ease of use.

Title: Optical contrast scanning method and device for carrying out the method
Inventor: ZIMMER KARL F
IPC: H04N1/40
Filed: 1985-10-16
Abstract: In order to prevent the picture from being "blurred" in an optical contrast scanning method, particularly when CCD photodiodes are used, when the object being scanned is moved in the direction of the measuring axis during two immediately successive scanning processes, the exposure time and the scanning time are synchronised with one another in such a manner that the photocells are alternatingly subjected to the exposure at predetermined exposure intervals for scanning. This is advantageously done by using a stroboscopic lamp as the light source or by arranging an inertialess shutter in the beam path.

Patent DE-3545748-A1 (DE)
Title: Assembled floor or intermediate-floor covering
Inventor: BATTERMANN WALTER
IPC: E04F15/024
Filed: 1985-12-21
Abstract: In order to protect vibration-sensitive equipment and instruments, in particular electronic computers, against interfering forces from the sound-reflecting structural parts around them, it has proved successful to set them up on floor coverings assembled from flexurally elastic studded slabs. In this arrangement, said studded slabs produced from rubber or rubber-type plastics rest on the floor structure by means of the cylindrical or frustoconical studs formed on their underside and butt directly against one another with the cut bordering edges. According to the invention, adjacent studded slabs are connected to one another with the aid of flexible-tube rings or strips pushed releasably onto respectively opposite studs, thus forming an open joint which is secured by inserted spacers. This results in a surprising degree of rigidity and dimensional stabilisation of the slabs, in particular in their edge regions.
