Title: Metering apparatus for an analyser
Inventor: FAEHNRICH VLADIMIR DIPL ING
IPC: B01L99/00
Filed: 1984-04-06
Abstract: The invention relates to a pneumatically controlled automatic metering apparatus for the two-phase measurement of chemical solutions in an automatic analysing unit, including the elements for automatic monitoring to ensure that the apparatus is functioning correctly. The invention essentially resides in the use of a cam program transmitter for initiating the operation of the air pump and simultaneously the movement of the two-armed lever for mechanically closing the outlets of individual branches of the compressed air distributing system. Furthermore, a contact bundle for indicating malfunction of the apparatus is arranged on the lever, which contact bundle is connected to the low-pressure system of the monitoring system of the main operating reflector surfaces. The system for distributing the air pressure consists of a preparation branch, an actuation branch and an auxiliary branch. The safety cavities and the chambers for safeguarding correct function of the apparatus in the event of sudden changes in the ambient temperature are formed in the pressure pipes of the blocked supply containers of the metered solutions. The invention can be used in particular in automatic photometric analysing units, in which the sample is continuously prepared by the admixture of a plurality of reagents at predetermined intervals. <IMAGE>

Title: Adaptive equaliser for digital data transmission systems with a transmission speed above the Nyquist frequency
Inventor: HENTSCHKE SIEGBERT DR ING
IPC: H04L25/03
Filed: 1984-04-14
Abstract: Non-linear equalisers are used at the receiving end in order to be able to make use of limited-band transmission channels, for example telephone subscriber lines, for digital signal transmissions with bit repetition frequencies above the Nyquist frequency. The known equaliser types are still far removed from the information-theoretical limits in terms of the signal-to-noise ratio required for the transmission channel. To remedy this, an equaliser is described which has the basic structure of a transverse equaliser, at whose taps, however, products from feedback coefficients (h1 to hk) allocated to said taps and from the output signal of a discriminator (2) connected downstream from the transverse equaliser are added according to the invention. In the adapted condition of the feedback coefficients, the pulse response present in the transverse filter is thereby completely compensated immediately following the discrimination and the signal-to-noise ratio at the output of the discriminator is increased as a result. <IMAGE>

Title: Process for producing machine components which can be highly stressed statically and/or dynamically
IPC: C21D9/00
Filed: 1984-09-21
Abstract: Processes are specified for the production of machine components which can be highly stressed statically and/or dynamically. Precipitation-hardening and/or micro-alloyed steels forming a fine grain are used as material. The machine components are first either, after a treatment or shaping process, starting from a temperature at which the structure is ferritic-perlitic, heated to a temperature between 800 DEG C and 1000 DEG C, or, after hot-forming by rolling, forging or pressing from final deformation temperatures, further treated under control between 800 DEG C and 1150 DEG C. The machine components are then cooled from said temperatures under control by a gaseous or liquid coolant or a coolant in a form atomised as a spray mist, or by fluidised-bed cooling, at a cooling rate, which effects in a machine component a precipitation hardening and/or fine-grain formation and as complete as possible a ferritic-perlitic structure, while avoiding significant formation of bainite, to a temperature at least 50 DEG C below that at which the conversion to ferrite and perlite is complete.

Filed: 1986-03-04
Abstract: An interrupter switch, especially for insulated electrical overhead lines, has a housing (1) which is open on one side and in which the stationary contact elements (3) are arranged. A switching cover (7) is detachably hinged on the housing (1) in two different arrangements by means of bearing elements (10, 13, 14) which engage detachably in one another and, in one of its limit positions, it closes the housing (1). It carries at least one switching contact element which is fixed in it, makes contact with the stationary contact elements (3) in the closed position of the switching cover (7) in one arrangement, and is located at a distance from the stationary contact elements (3) in the other arrangement. In both arrangements, when the switching cover (7) is in its closed position, its side which carries the switching contact element (9) points towards the housing (1). However, it is at a greater distance from that side of the housing (1) which faces it in one arrangement than in the other arrangement. <IMAGE>

Title: Piezoelectrically operated print head for ink jet matrix printers
Inventor: JOHANNSEN FRED DIPL ING
IPC: B41J2/14
Filed: 1986-03-19
Abstract: Known piezoelectrically operated print heads for ink jet matrix printers consist of a plurality of plates which are firmly connected to one another and in which the ink ducts, the damping members, the compression chambers and the nozzle outlet apertures are formed. In this case, the nozzle outlet apertures consist of two halves which are of mirror-symmetrical design and are formed in the surfaces of two plates to be connected. Since the symmetrically designed halves of these outlet apertures are produced in separate operations and in different plates, it cannot be ruled out during assembly that the two plates will become offset. The nozzle halves arranged offset lead to uneven ink droplet intervals on the recording media. According to the invention, this disadvantage is reliably prevented by means of a centrally arranged nozzle plate (6) in whose opposite outer surfaces (23, 48) there are arranged in each case a row of outlet apertures (2, 22) and the associated ink ducts, recessed in the manner of a groove, and by means of planar cover plates (25, 49) which cover the depressions. As a result, alignment errors during assembly as well as uneven diameters of the outlet apertures (2, 22) are reliably prevented, since the depressions in the outer surfaces (23, 48) of the nozzle plate (6) are produced in one etching operation with the same etching time. The print head according to the invention therefore guarantees even ink droplet intervals in the case of... Original abstract incomplete. <IMAGE>
