Abstract: The burner head has a fuel lance (1) which runs through the burner head in its length and which ends on the downstream side with a fuel nozzle (2). Acting around this fuel lance (1) is a combustion air duct (4) which stops on the downstream side with a screen (3). Arranged around this first combustion air duct (4) is a further combustion air duct (6) which passes on the downstream side into an outlet, where a number of guide members (9) is situated, which impose a twist on at least the combustion air flowing through this duct. Also affected by this twist are the waste gases (10) flowing in through a tangential duct (11) in the region of the guide members (9), as a result of which there is good mixing between the two media. Acting on the downstream side of the fuel nozzle (2) is a premixing zone (8), adjoining the end of which is a vortex backflow zone (14), As far as this vortex backflow zone, the combustion chamber is provided with a premixing pipe (13), and subsequently a combustion pipe (19, 19a) acts, which has a greater cross-section in relation to the premixing pipe (13). At the transition of these two pipes, a vortex ring (17) is formed, which surrounds the vortex backflow zone (14) and ensures that the flame stabilisation is maintained, by the last-mentioned zone not being able to flatten. The initial ignition (18) of the mixture takes place in the vortex ring (17).

Abstract: In a photoelectric position measuring device according to Figure 4, reference marks which define in an absolute fashion the relative position of the scale and scanning plate are coded. Different diffraction images are produced with the aid of coding marks which are assigned to the reference marks and consist of differently diffracting fields (C1 to Cn). These diffraction images are detected by appropriately placed photoelements (D1, Dn), converted and output as a binary code. The binary code specifies the absolute position in coded form. The number of the fields in the coding mark determines the number of the decodable reference marks. That is to say at least 2<n> reference marks can be coded using n code mark fields. <IMAGE>

Abstract: In a sheet-fed offset press having at least one printing unit in which the blanket cylinder can be thrown on and off the impression cylinder and plate cylinder by a pressure-medium-energized actuating arrangement, the pressure medium energization is triggered by a control unit in accordance with the position of grip edge zones of the cylinders being in registration. In order to ensure that throwing on and throwing off take place when the grip edge zones of the cylinders are positioned immediately opposite one another, the control unit detects the position of the printing unit cylinders relatively to one another by way of an angular position sensor and also detects the actual speed of the press via a speed sensor. The control unit forms speed-dependent throw-on and throw-off actuating times which are advanced in the direction of rotation of the printing unit cylinders so that the reaction time is outside the time slot for grip edge zone registration. The invention reduces the very substantial constructional outlay needed in the case of pressure-medium-energized actuating arrangements to ensure reliable throw-on and throw-off at high printing speeds.

Date Feb. 20, 1992.Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas. N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert organic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporization of the solvent, so limiting increases in reaction temperature and suppressing the dissociation of the N2O5. In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recalculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

The probe system has a waveguide (28) incorporated in a low-noise block receiver (12) into which two probes (34, 38) are located for receiving linearly polarised energy of both orthogonal senses. The probes (34, 38) are located in the same longitudinal plane on opposite sides of a single cylindrical bar reflector (36) which reflects one sense of polarisation and passes the orthogonal signal with minimal insertion loss, and then reflects the rotated orthogonal signal. The probes (34, 38) are spaced  lambda /4 from the reflector (36). A reflection rotator (44) is also formed using a thin plate which is orientated at 45 DEG  to the incident linear polarisation with a short circuit (46) spaced approximately a quarter wavelength ( lambda /4) behind the leading edge of the plate (43). This structure splits the incident energy into two equal components in orthogonal planes, one component being reflected by the leading edge (43) and the other component being reflected by the waveguide short circuit (46). The resultant 180 DEG  phase shift between the reflected components causes a 90 DEG  rotation in the plane of linear polarisation upon re-combination so that the waveguide outputs (34a, 38a) are located in the same longitudinal plane. Various embodiments and advantages of the invention are described.
