IPC: B01D53/68
Filed: 1978-11-28
Abstract: In the purification of waste gases containing nitric oxides, iodine and iodine compounds and triturated water vapour from a nuclear reprocessing plant, hyper-azeotropic nitric acid is introduced at the head (6) of a counter-current gas/liquid contact column (4) and then conducted through a co-current contact column (1) where it is cooled to a temperature of up to -65 DEG C. Waste gas to be purified (22) is introduced into the head of column (1), and thence follows the path (23), (24) and (7).

Title: Releasable carriage drive unit for an optical disc player
IPC: G11B7/085
Filed: 1979-02-17
Abstract: An optical disc player comprises a read objective on a carriage which is translated to and fro with the aid of a drive unit with an electric motor by cooperation of a drive pinion and a gear rack, so that the read objective travels between a minimum diameter and a maximum diameter of the disc to be read, between which the information is contained. A pinion and a gear wheel of the drive unit cooperate with each other without play, in that the pinion is mounted on a pivoting member which is resiliently loaded, so that the pinion and the gear wheel are in resilient engagement with each other. During work on the optical disc player the pivoting member can be pivoted away by hand, so that the teeth of the pinion and the gear wheel are disengaged from each other so that a quick, practically unhampered translational movement of the carriage is possible.

Abstract: A process provided for the production of 2-nitrobenzaldehyde from 2-nitrotoluene, in which 2-nitrotoluene is converted, by bromination by a radical mechanism, to 2-nitrobenzyl bromide in the form of a bromination oil containing 20 to 50% or more of 2-nitrobenzyl bromide, and the bromination oil is oxidized directly with a mixture of dimethylsulphoxide and sodium bicarbonate in a weight ratio of 3:1 to 10:1 at temperatures of up to 100 DEG C. and the 2-nitrobenzaldehyde is subsequently isolated via the bisulphite adduct, to give 2-nitrobenzaldehyde in high purity and high yield. The process also has the advantage of a very short reaction time. The 2-nitrobenzaldehyde produced is an important intermediate, for example in the production of pharmaceutically active 1,4-dihydropyridines.

Title: Process and apparatus for the recuperation of maleic anhydride from a phthalic anhydride gaseous reactor effluent.
IPC: C07D307/60
Filed: 1983-11-21
Abstract: A process for the recovery of maleic anhydride contained as a by-product in a phthalic anhydride gaseous reactor effluent is described. This process consists of gas scrubbing in order to obtain an aqueous solution of the maleic acid and the other organic substances contained in the gas, including phthalic acid, concentration of this solution as maleic acid to a concentration of 25-35 % by weight by addition of a return stream to the solution and removal of the phthalic acid by crystallisation. The resultant solution, rich in maleic acid and depleted in phthalic acid, is then partially fed back into the gas scrubbing step (in order to promote the solubility of the phthalic acid and to enrich the solution of maleic acid thus obtained) and partially submitted to a treatment to recover the maleic anhydride by dehydration by means of azeotropic distillation with ortho-xylene. The resultant crude maleic anhydride is then purified by rectification in plate-type columns. An apparatus for the recovery of maleic anhydride is also described which includes a gas scrubbing section, a maleic acid dehydration section and a maleic anhydride purification section.

Title: Drive with single hydraulic cylinder for universal type punching shears
IPC: B26D9/00
Filed: 1984-01-19
Abstract: A punching and shearing machine in which a single hydraulic cylinder (1) operates alternatively the punch or the shear of the machine. When the punch is operative, a manually operated eccentric lever (16) blocks the shear carrying member (8) so that the stem (6) of the piston in the hydraulic cylinder (1) causes motion of the punch carrying member (3). If, on the other hand, the shear is to be operated, another manually operated eccentric lever (14) blocks the punch carrying member (3), so that the external part of the hydraulic cylinder, which is connected to the shear carrying member (8), causes the motion of the shear carrying member only. Safety micro-switches are provided to interrupt the hydraulic circuit controlling the cylinder (1), if the eccentrics (14, 16) are both free or both are blocking a tool carrying member.
Patent ES-8500700-A1 (ES)
Title: Circuit board fabrication leading to increased capacity.
IPC: H05K3/34
Filed: 1984-02-15
Abstract: Printed circuit boards having a plurality of circuit layers are produced using a specific processing sequence. A copper-clad substrate (31) is first patterned in a desired configuration to produce the first layer of the printed circuit board. The patterned metallization (32) is then covered with a specifically formulated energy sensitive material (Fig. 3B). The energy sensitive material is delineated in a desired pattern and developed to uncover portions of the underlying metallization pattern. The entire substrate is blanket-cured to produce a rigid layer having openings in appropriate places. The openings are metallized (34, 35) and a second copper pattern is produced on the cured polymer by conventional metallization and lithographic techniques. If desired, the process is repeated until a suitable number of copper patterned levels are obtained.
