Title: Process for metering eluents in HPLC by FLOW FEEDBACK using a metering valve and an eluent-independent flow metering system
Inventor: KAGE ANDREAS DR
IPC: G01N30/36
Filed: 1984-05-30
Abstract: The pumps currently used in HPLC, because of their relatively large dead volumes, unassured constancy of mass transport and lack of freedom from pulsation are able only in a restricted manner to achieve sufficiently reproducible or constant outputs even at very low pumping outputs. The pump system to be patented offers here a solution in which, in contrast to the conventional pumps, by means of a spatial and functional separation of pressure generation, eluent transport and eluent metering, a virtually pulse-free eluent stream, gradient mixing in the high pressure range, rapid change to another eluent and constant mass transport of the eluent are ensured. The pump system is composed of a pressure-generating unit, eluent-transporting heads and a metering unit. Since all units are spatially separated, separate multiplication of each individual component is possible at any time. This modular construction is especially suitable for the increasingly frequently described column circuits in HPLC, since here a greatly differing number of HPLC strings can be used with different numbers of eluents and changing eluents. Likewise, multiple HPLC systems can be operated with significantly lower complexity. Even a plurality of these systems can be connected together in a simple manner and cause in relatively large systems, by reduction of a number of elements, which ... Original abstract incomplete.

Patent DE-3445922-A1 (DE)
Title: Protective coating process
Inventor: STANGER REINHARD
IPC: B05D1/18
Filed: 1984-12-17
Abstract: In a process for the production of protective coatings of plastic at edges, corners and supporting surfaces of metal parts and other rigid articles in an immersion process, in which the reactive starting components of the plastic are applied as a liquid mixture to the edge, corner or supporting surface to be coated and subsequently harden into the plastic, an immersion coating at room temperature and subsequent rapid hardening of the protective coating are achieved, with considerable saving of energy and simultaneous achievement of an adjustably thick protective coating whose form is freely selectable, when the liquid mixture consists of UV-hardenable reaction resin, a reactive diluent and a photoinitiator and has a comparatively high viscosity at the processing temperature, and when after the application a distribution of the liquid mixture is undertaken until the desired coating thickness is reached, after which the layer is irradiated with UV or electron beams until it has hardened.

Title: Letter envelope for the mechanical, automatic further processing of post
Inventor: STEIN MICHAEL
IPC: B65D27/00
Filed: 1985-01-04
Abstract: The invention relates to a letter envelope - which may be a window envelope - for the mechanical, automatic further processing of post. It is known that the further processing of post in, for example, post-office sorting rooms has to be undertaken manually in a cost-intensive manner for lack of suitable markings which can be efficiently read by machine and are completed or identified in advance, in a variable manner, by the sender. The invention avoids this disadvantage by establishing and applying a standardised and harmonised marking on the letter envelope which can also be transferred to other postal material, and which is particularly characterised in that, despite its standardisation and normalisation, it is variable within the range of cybernetic possibilities and can therefore be completed by the sender. The introduction of the letter envelope according to the invention creates substantial advantages in terms of efficiency and hence leads to dramatic cost reductions and to greatly improved postal services.

Title: Method for the regeneration of a soot filter of an air-compressing internal combustion engine
Inventor: BERGMANN HORST DIPL ING
IPC: F01N3/025
Filed: 1985-08-01
Abstract: The invention relates to a method for the regeneration of a soot filter of an air-compressing internal combustion engine with a fuel injection pump having a control rod and with a burner arranged in the exhaust system upstream of the soot filter, which burner can be switched on and off by a control unit sensing combustion process parameters. In order to obtain an exhaust gas temperature necessary for regeneration of the soot filter by using a burner and a process temperature increase of the internal combustion engine, the instantaneous load state of the internal combustion engine is determined in the control unit from the speed of the internal combustion engine and the control rod travel during operation of the burner and compared with a previously determined load state value specific to the internal combustion engine. Below the load state value specific to the internal combustion engine the combustion air flow is reduced by means of a throttle valve located in the intake flow. Once a predetermined length of time has elapsed in which the pressure upstream of the soot filter falls short of a predetermined exhaust back pressure, the regeneration process is terminated by switching off the burner and cancelling the throttling of the combustion air.

Title: Method and arrangement for marking and recognising objects
Inventor: KAPPNER HELMUT A
IPC: G06V30/224
Filed: 1985-11-27
Abstract: In a method for recognising objects, particularly documents, workpieces and transport means on which a durable coding is applied which consists of segmented plain-text characters which are both man- and machine-readable, orientation characters are also applied to the object which have a predetermined position with respect to the coding. The coding and the orientation characters are recorded by an electronic camera, the output signals of which are conducted to an image processing computer. During this process, scanning masks are generated which assume the expected position of the orientation characters within the recorded image and the area of which exceeds that of the orientation characters. Those characters which are located within the masks are recognised as orientation characters and their coordinates are calculated. By these means, the accurate position of the coding is determined and further masks scan the coding. The invention also comprises arrangements for carrying out the method according to the invention and methods and arrangements for marking the objects.
