IPC: C07C51/265
Filed: 1988-10-05
Abstract: A novel method of oxidizing di- and trimethylbenzenes with molecular oxygen to the corresponding di-or tricar­boxylic acid under liquid-phase conditions is disclosed. The process is conducted at a temperature of about 100°C to 260°C. This process comprises conducting the oxidation in the presence of a catalyst system comprising a source of bromine with nickel, manganese and zirconium. The ben­zene di- and tricarboxylic acids have wide industrial application, including the manufacture of polyesters, polyamides, and fibers and films.

Abstract: The high-luminance colour screen for cathode ray tubes comprises two luminophores which fluoresce in different colours. The visible track formed on these luminophores by electron bombardment has a colour which can be adjusted by varying the accelerating voltage of the electron beam during operation between two extreme values V0 and V1. The two luminophores (2, 4) are arranged on the transparent support (1) of the screen in superimposed layers made of crystalline powders of each of the luminophores. The layers are separated from each other by a barrier with plane surfaces (3). The screen is mainly noteworthy in that the barrier with plane surfaces (3) consists of a first silicon dioxide layer (31), a zinc sulphide layer (32) and a second silicon dioxide layer (33), with the zinc sulphide layer lying between the two silicon dioxide layers. …<??>Application to beam penetration tubes. …<IMAGE>…

Abstract: The haymaking machine comprises a tubular crossmember which can be suspended or mounted on a tractor and is aligned essentially horizontally in the operating position and which has a middle bearer (1) and, on each of the two sides, a lateral bearer (4,5) connected to this in an articulated manner about a main pivot axis (2,3) approximately parallel to the direction of travel and respectively comprising an inner part (25) and an outer part (28). Furthermore, the machine comprises a number of rotary rakes (6,6.1,7,8,9,9.1) which have raking prongs (11) directed towards the ground in the operating position and which are mounted rotatably about vertical axes (12) on the crossmember and can be driven by means of a drive shaft (29) mounted in the crossmember, and running wheels (14) which are each arranged under a rotary rake (6,6.1,7,8,9,9.1) in each case. A pressure-medium drive (17,18) assigned to each lateral bearer (4,5) serves for pivoting the lateral bearers (4,5) upwards and for fixing them in a transport position, the outer part (28) of each lateral bearer (4,5) being equipped only with one rotary rake (6,9) and being pivotable by means of an adjusting lever (33) into a transport guard position relative to the adjacent inner part (25) about an additional pivot axis (23,24). The additional pivot axes (23,24) are aligned approximately parallel to the direction of travel, and the outer parts (28) are connected tiltably about these to the inner parts (25) of the lateral bearers (4,5). The adjusting rod (33) is designed as a pull and push rod which engages directly on the outer part (28) via a joint (34) with a joint axis parallel to and at a distance from the additional pivot axis (23,24) and which, in the two end positions of the lateral bearers (4,5), locks their outer part (28) in its respective tilt positions relative to the adjacent inner part (25).

Abstract: Un appareil et un procédé identifient et mesurent des interruptions aléatoires de contacts dans un dispositif d'interconnexion de circuits. Un circuit comparateur (41), opérant à des fréquences élevées, identifie l'occurrence d'une interruption. Suite à l'interruption, le circuit comparateur amène un circuit compteur de haute fréquence (44-46) à compter des impulsions d'horloge. Le comptage du circuit compteur d'horloge est continuellement fourni à un circuit de mémoire à accès aléatoire (RAM 51-55), validé pour l'écriture à une adresse de la mémoire. A la fin de l'interruption, le circuit RAM (51-53) n'est plus validé pour l'écriture à l'adresse donnée, cette adresse étant modifiée (incrémentiellement) en préparation pour la prochaine interruption (38-39). Le circuit compteur est également remis à zéro en préparation pour la prochaine interruption. Le nombre d'unités comptées par une unité d'horloge ayant une fréquence connue indique la durée de l'interruption. On peut ainsi identifier, en utilisant une unité d'horloge opérant à 100 MHz, des interruptions d'une durée comprise entre 10 nanosecondes et 9,99 microsecondes. Compte tenu de la fréquence à laquelle le contrôle est effectué, il faut ajuster l'impédance d'entrée du circuit comparateur à l'impédance du dispositif d'interconnexion de circuits.

Date Jan. 25, 1990.In casings for switch cross ties, the bottom plate 3 serves at the same time as a pattern for the position of the construction components. As a rule, a new casing is prepared for each series of cross-ties type. In small series with various positions of the construction components it is economical to use the bottom plate repeatedly. This is done by providing the bottom plate, prior to its insertion in the casing, with holes (A,B,C) for several types of finished parts, by provisionally closing the unnecessary holes by suitable means and by finding the combination of holes required for the production of a certain type of finished part through a certain searching procedure and freeing them of their provisional closing means.

Abstract: In the procedure for the installation of plastic pipe pieces with lateral branch openings into sewage pipes to be repaired, the first step is the measuring in the longitudinal axial direction of the branch of the sewage pipe from the inside with respect to the already installed piece of plastic pipe. After that, a lateral opening is formed in the plastic pipe while the pipe is above ground and outside of the sewage pipe. Next, the already prepared plastic pipe is joined in an aligned position with the already installed plastic pipe, with the help of a movable transporter inside the sewage pipe.

Abstract: In accordance with Figure 1, in an interferometer of integrated optical design, a beam (5) emanating from a laser diode (4) falls into a circular grating (2). There, it is split into two component beams of 0th and 1st order. The 1st order forms the reference beam, which is focused into a coupler (7). The 0th order forms the measuring beam, and is projected through a triple prism (6) on to a second circular grating (3), which focuses the measuring beam (0th) into the coupler (7). The 0th and the 1st order interfere in the coupler (7), and interference signals are generated in a known way and converted by detectors (8a, 8b, 8c) into mutually phase-shifted electrical signals.

Abstract: A positive displacement pump has two separate outlet passages, 16, 17 leading to a main outlet passage 18 containing a constant flow orifice 20. Outlet passage 17 contains a non-return valve 19. A control valve member is mounted in a bore opening to passage 18 upstream to orifice 20. The bore has an annular overspill port 31 and a by-pass port 34 which opens to outlet passage 17 upstream of valve 19. The valve member has two lands 29, 30 having end faces co-­operating respectively with annular edges 31a, 34a of ports 31, 34. Notches 35, 36 are respectively formed in said end faces. On increasing pressure upstream of orifice 20 moves the valve member to by-pass the delivery from passage 17 to the overspill. Further increase of pressure then causes closure of the valve 19 and causes the valve member to move suddenly to pass fluid from passage 18 to the overspill port 31.
