Title: Drainage device for the catalytic converter container
Inventor: STARZYCZNY JOSEF
IPC: F01N3/00
Filed: 1984-10-29
Abstract: We count the catalytic converter as one of the relatively expensive devices of a motor vehicle. In view of the fact that its purchase cost is fairly high and that in the event of wear in practice only the catalytic converter insert is replaced and the original shell or the body of the catalytic converter is retained, we must endeavour to prolong its service life as far as possible. With the use of the drainage device the inside of the shell of the catalytic converter remains dry after each journey, thereby greatly reducing the internal corrosion. Fitting this simple device into the catalytic converter should not increase the manufacturing costs greatly but contribute to extending the service life of its shell and thus also lead to savings for the consumer.

Title: X-ray diagnosis device having an image-amplifier television chain
Inventor: FRENZ DIETRICH DIPL PHYS
IPC: H05G1/64
Filed: 1985-02-23
Abstract: The invention relates to an X-ray diagnosis device having an image-amplifier television chain, a dose-power control loop and at least one electronic image memory. The invention is based on the object of creating an X-ray diagnosis device by means of which the X-ray dose is saved in comparison with penetration illumination, as a result of the capability for continuous reproduction of in each case one stored X-ray television image, while at the same time the image quality is improved by reducing the quantum noise. This is achieved according to the invention in that memories are provided in which, on completion of the recording of an image in the image memory, the values set on the X-ray generator for this image recording, by means of the dose-power control unit, for the X-ray tube voltage and the X-ray tube current, are stored, and in that these values are used as initial values for the dose-power control for the subsequent image recording. The invention can be used in particular for the case when it is intended to observe processes which change only slowly in the X-ray image, that is to say the transparency of the object changes only slightly in the time between two images being stored as is the case, for example, during surgical investigations.
Patent DE-3508064-A1 (DE)
Title: Control system for hot-water heating installations
Inventor: NIXEL FRITZ DIPL ING
IPC: F24D19/10
Filed: 1985-03-07
Abstract: To supply a heating circuit (17), use is made of a heating boiler (10), in particular a solid fuel heating boiler, and/or a heat accumulator (23). To remove heat from the accumulator (23), a four-way valve (21) adopts its first position, in which the forward run line (12) is connected directly to the return run line (14) via a connecting line (22) and a line branching off from the heating circuit (17) is connected to a heat exchanger (24). Correspondingly, the circulating pump (18) of the heating circuit (17) can generate a circuit from the heating systems (19) via the heat exchanger (24) and the mixing valve (16). At the same time, when the boiler (10) is set in operation, its temperature can be raised rapidly by the direct connection between forward run line (12) and return run line (14). With adequate boiler temperature, the four-way valve (21) is reversed so that the branch line (20) as well as the return run line (14) are connected. The hot forward run water is then supplied to the heating circuit (17) and/or via a further heat exchanger (25) to the accumulator (23). When the forward run pump (13) is switched off, the circulating pump can generate a circuit between the heating systems (19) and the boiler (10), in particular to utilise its residual heat.   <IMAGE>

Title: Process for the simultaneous scrubbing of SO2 and NOx from flue gases by the use of additives with low manganese content
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-12-12
Abstract: As specified in the main application P 3525051.8, it is known to scrub SO2 and NOx from combustion exhaust gases by the use of a wet-cycle scrubbing in which the scrubbing water contains iron(II) EDTA complex or iron(II) NTA complex. In order to obtain the iron(II) complex within the scrubbing solution, reducing agents are added or scrubbing water treatment processes are carried out in bypass operation in order to further reduce the iron which was oxidised by means of atmospheric oxygen from iron(II) to iron(III) in the chelate complex and thus to minimise the use of expensive reducing agents. In order further technically and economically to improve this process, in particular to reduce the consumption of reducing agent, it is proposed according to the invention that the iron(II) salts, preferably iron(II) sulphate, and calcium oxide, in particular hydrated lime, used for preparing the scrubbing solution, have a manganese content of less than 0.05 to 0.07% based on the dry substances.

Title: Circuit arrangement for feeding electrically erasable and programmable non-volatile memories in telephone terminals
Inventor: BAHR FRANK
IPC: H04M19/08
Filed: 1986-04-14
Abstract: To feed electrically erasable and programmable non-volatile memories in telephone terminals which are supplied with power via the connection lines, a parallel voltage regulator controlled by a high-precision reference is used which is inserted immediately downstream of the polarity reversal protection of the telephone terminal between the line wires and thus secures the relatively high voltage requirement of the memory in dialling mode. The parallel voltage regulator and the reference furthermore serve as an electronic dial pulse contact. A conventional memory with a memory capacity which is significantly higher than that required for the application concerned is used as the non-volatile memory.
Patent DE-3614944-A1 (DE)
Title: Simultaneous scrubbing process for desulphurisation and simultaneous denitrification of flue gases downstream of refuse incinerators
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-05-02
Abstract: It is known to control sodium-based or calcium-based flue gas desulphurisation plants with an EDTA complex via a scrubbing water solution in such a way that SO2 and NOx are scrubbed out simultaneously. The difficulty in this scrubbing process is that it is as a rule difficult to keep the Fe2 complex in the scrubbing solution stable. High oxygen values of, for example, 7% and more lead to enhanced oxidation of the Fe2 value and hence to a steep decrease in the separation of NOx. In order to eliminate these disadvantages, it is proposed according to the invention that magnesium salts in the form of magnesium chloride or magnesium sulphate are added to the iron chelate complex solution in the scrubbing liquid, whereby an oxidation of iron II to iron III by the oxygen content of the flue gases being scrubbed is attenuated. The addition of magnesium chloride and/or magnesium sulphate suppresses the solubility of sodium sulphate and promotes a precipitation with lime.

Patent DE-3630742-A1 (DE)
Title: Chopper
Inventor: VOLZ OTTO
IPC: A01F29/02
Filed: 1986-09-10
Abstract: To improve the flow of material in a disc-wheel or drum chopper, it is proposed to arrange an annular disc or friction drum behind the chopping wheel or within the chopping drum and to cause the rotating chopping cutters to cooperate directly with the counter-tools of the annular friction disc or friction drum so as to form a friction gap. The material to be chopped, in the particular portion just cut off, is thereby directly introduced immediately into the friction gap along the cutter rear side, without being thrown outwards beforehand.   As a result of this uniform feed of material without bunching together, the chopper works smoothly, has a high throughput and is of simple construction.
