Abstract: A monopulse receiver (100) includes a monopulse antenna and arithmetic unit (15) for providing a monopulse sum signal, S, an azimuth difference signal, y, and an elevation difference signal, p, an imbalance correction circuit (10) to provide a first composite signal defined as (p+jy) and a second composite signal defined as (p-jy), wherin j is an indicator of being in quadrature with the monopulse sum signal, and for interleaving the first and the second composite signals for providing a composite difference signal, D, and a combiner (21) for providing a third composite signal defined as [S+D] and a fourth composite signal defined as [S-D]. The monopulse receiver further includes a switch matrix (23), for feeding the third composite signal to a first amplifier channel (25A) and for simultaneously feeding the fourth composite signal to a second amplifier channel (25B) during a first interval of time and, alternatively, for feeding the third composite signal to the second amplifier channel (25B) and for simultaneously feeding the fourth composite signal to the first amplifier channel (25A) during a second interval of time to provide an output signal from each of the first and second amplifier channels (25A,25B), and a second switch matrix (29) fed by each output signal from the first and second amplifier channels (25A,25B), to provide successively amplified third composite signals [S-D] at a first output line (TP4) and successively amplified fourth composite signals [S+D] at a second ouput line (TPS). With this arrangement, the effects of phase and amplitude imbalances in the monopulse antenna and arithmetic circuitry are reduced.

Abstract: A photographic printer for processing excessively long strips of spliced lengths of printing originals, in particular negative film strips (N) which can be wound onto film spools, has an exposure station (2) which is disposed along a transport track (T) of the negative film strip (N) and in which the negative film strip (N) is exposed original by original onto unexposed photographic printing material, in particular onto unexposed photographic paper (F), which is guided along a paper path (P) extending inside the printer (1), preferably below the film transport track (T) through the exposure station (2). The printer (1) is fitted with two storage spools (5, 6), which are disposed on the input side (3) of the photographic printer (1) and from which the negative film strip (N) can be optionally wound, and with two take-up spools (7, 8), which are disposed on the output side (4) of the printer (1) and onto which the negative film strip (N) can optionally be wound after passage through the printer (1), one storage spool (5) and one takeup spool (7) each being connected to the negative film strip (N) currently being processed, and the respective other spools (6, 8) being in the waiting position. The configuration according to the invention of the photographic printer (1) consists in particular in that the storage spool (5) and takeup spool (7), which are connected in the working position to the negative film strip (N) currently being processed, are each disposed in an approximately rectilinear extension of the film transport track (T) immediately adjacent thereto, while the film spools (6, 8) in the waiting position are disposed in an approximately rectilinear extension of the film transport track (T) behind the film spools (5, 7) which are in the working position. <IMAGE>

Abstract: PCT No. PCT/GB91/00241 Sec. 371 Date Aug. 24, 1992 Sec. 102(e) Date Aug. 24, 1992 PCT Filed Feb. 18, 1991 PCT Pub. No. WO91/13058 PCT Pub. Date Sep. 5, 1991.A dilute solution of a lower aliphatic peracid such as peracetic acid, having an equilibrium composition, is produced by contacting hydrogen peroxide with a lower aliphatic acid each at initial high concentrations in an aqueous reaction mixture to rapidly form a reaction mixture containing, for example, up to 30% by weight of peracid and diluting the reaction mixture with water and with any required quantities of lower aliphatic acid and/or hydrogen peroxide to reproduce the equilibrium composition of the dilute solution, the process being characterized in that the reaction mixture rich in lower aliphatic peracid is diluted before it has itself reached equilibrium, for example when it contains from 20 to 80% of its potential equilibrated content of peracid. The process provides a quick plant-efficient process for the production of stable dilute lower aliphatic peracid solutions for industrial disinfection purposes or for personal or domestic hygiene use.

Title: Process for the high-frequency data transmission of driving information and devices therefor.
Inventor: BRAEGAS PETER
IPC: G01C21/20
Filed: 1991-11-06
Abstract: The proposal is for a process for the high-frequency data transmission of driving information from fixed beacon transmitters (2, 4) to vehicles (7, 8) in which there are at least two fixed beacons. To prevent the extinction of the wave field of the at least two beacons (2, 4) by standing waves it is proposed to modulate the high-frequency signal of the beacon transmitters with a spectrum similar in noise so that standing waves cannot form. In this way all vehicles passing the beacons can receive the information transmitted by them without the occurrence of interference by the extinction of wave fields.

Abstract: An advancing apparatus for sheet film (17) has a first pair of transport rollers (3, 5) effecting transport of a sheet film (17) fed to the roller nip by suction means. The pair of transport rollers (3, 5) mounted on rotatable shafts (2, 4) is associated with a reflective switch (14) provided in the transport path of the sheet film. The reflective switch (14) arranged above the transport path of the sheet film (17) is associated with a mirror (10c) which is positioned beneath the transport path of the sheet film (17) and towards which the sensor of the reflective switch (14) is directed. Mirror (10c) is mounted to a retaining means (10) which is supported in a space-saving manner on the shaft (2) arranged beneath the film transport path and positively engages with a stationary stop means (11) preventing rotation. With respect to the transport plane of the sheet film (17), mirror (10c) is arranged in an inclined position so that the sensor directed towards the mirror also extends at an angle relative to the sheet film plane. This arrangement guarantees that no erroneous signals are produced since a sheet film (17) passing the reflective switch (10c, 14) deflects the sensor beam so as to be ineffective.

Abstract: An improved powertrain control which recognizes the occurrence of engine speed flare during low torque upshifting, and effectively converts the shift to a power-off upshift via an override of the normal engine torque management controls. The engine spark timing is retarded by a predetermined amount during every power-on upshift for the reasons described above. However, when the occurrence of engine flare is detected, the control increases the spark retard to a maximum value, substantially eliminating the transmission input torque. As the on-coming element smoothly applies and decelerates the input, the flare condition terminates, and the spark timing is returned to the predetermined amount for completion of the shift.

Abstract: An improved eutectic aluminium-silicon alloy having a relatively high level of bismuth is provided which is particularly wear-resistant and sufficiently self-lubricating so as to be suitable for use in a wearing component even when poorly lubricated. The relatively high bismuth level within the alloy co-operates with the other elemental additions present so as to provide a sufficiently low-friction bearing surface (or self-lubricity), which significantly enhances the wear-resistant properties of the alloy. In addition, the preferred alloy also has relatively substantial additions of both nickel and copper, which results in the homogeneous distribution of hard wear-resistant nickel and copper phases throughout the alloy. The formation of components from the improved aluminium alloy should minimize wear and alleviate galling of those components during use.
