IPC: C08G69/32
Filed: 1971-07-06
Abstract: Aromatic polycyanoamides (I). (A, B = aromatic substituents; X1 = H or CN (not ortho to carboxyl gp.); X2 = H or CN), are heated at 100 - 450 degrees C (pref. 200 - 300 degrees C) to give the polyiminoimidoamides: Specifically, A is e.g. m-cyanoisophthalic acid or a dicarboxylic acid e.g. 3-cyano diphenylsulphone-4,4'-dicarboxylic acid; B is e.g. o-phenylenediamine, 3,5-diaminobenzonitrile. (I) is prepd. by the condensation of dicarboxylic acid (dichlorides) with diisocyanates (diamines) at 100 degrees C. The solns. of (I) can be used for transparent, flexible film mfre. While at >200 degrees C, they become insoluble. Powdered (I) at >150 degrees C are used in thermoplastics with improved thermal stability.

Title: Re-acylation of esters - esp esters of unstable or non-existent free alcohols
Inventor: PLETTNER WOLFRAM DIPL CHEM DR
IPC: C07C323/52
Filed: 1972-03-23
Abstract: Esters are prepd. by re-acylation of esters, possibly in the presence of catalyst. A distillable ester, whose acid component is volatile is reacted with an acid which is chosen so that it is less volatile than that set free from the starting ester. The acid liberated is distd. off with the starting ester as a binary mixt. or a binary or higher mixt. is formed by addn. of such solvents that the b.pt. of this mixt. lies below the b.pt. of the acid added for the re-acylation. Simultaneously approx. the same amt. of ester removed by distn. and possibly solvent is led back into the reaction mixt. until interchange of ester radicals is complete. The process is partic. used for prepn. of esters whose alcohol component is unstable or non-esistent in the free state e.g. vinyl and allyl esters.

Title: Cut-off valve on delivery pipe for bulk material - has vibrating porous surface directing compressed air into pipe
Inventor: DENNENMOSER FRANZ
IPC: B65D90/62
Filed: 1973-06-29
Abstract: The pivoting hollow valve has a flexible inner side comprising a tensioned filter cloth supported by ribs and perforated discs. An airline feeds compressed air pulses into the valve before and/or during opening. These impulses cause the valve-surface to vibrate and allow air into the pipe in order to prevent blockages. Deposition of material on the reverse side of the pivoting valve is avoided, and the two perforated discs in the system support the filter cloth during the interval between the applied pulses of air.

Title: Electronic mean value determination - involves phase comparator and shift registers applied to cyclically varying parameter
Inventor: GRISARD KLAUS DR
IPC: G01P13/02
Filed: 1973-07-28
Abstract: An electronic logic system establishes the running mean of a cyclically varying parameter. It may determine the average position of a weather vane. The system is driven by a clock generator from which three waveforms are generated disposed in phase at 120 deg. intervals. These signals feed a potentiometer device attached to the weather vane, and the output of this switches a comparator to give an impulse chain of which the phase describes the angular position of the weather vane. A phase comparator compares this output with the original clock signal phase shifted by an amount determined by output of the phase comparator effectively integrated in an up-down counter. This feedback configuration results in the contents of the up-down counter being descriptive of the mean weather vane position and this is duly displayed.

Title: Cable core marking process using spray paint - is applied to preheated insulation to shorten drying time before cores are twisted together
Inventor: BRITZ HELMUT
IPC: H01B13/02
Filed: 1974-03-15
Abstract: The application is to the manufacture of multicore cables and concerns the identification of individual cores. Each insulated core, as it passes from its storage reel to the twisting or transposing head, passes a heater which raises the surface temperature of the insulation, and then a pigment applicator is used which sprays a band of identifying colour round it. The distance between the spray and the transposer is such that the insulation has cooled before reaching the latter and is not deformed. If faster through-put is required a cooling unit may be added before the cores are brought together.

Title: Slag removal from bead in bore of spiral welded tubes - continuous automatic scraping simultaneous with welding
Inventor: KOBAYASHI MASAMA
IPC: B23K9/18
Filed: 1974-04-26
Abstract: Flat strip is put through a forming machine so that it forms a tubular spiral. A carrying arm is inserted into the bore of the spiral, this arm projecting down the tube beyond the welding point. A welding jet is mounted on the arm so that the tube can be welded internally by submerged arc welding at the point where the flat tube meets the spiral. A block weighing about 80 kg. is attached by a chain to the end of the arm so that the block rests on the welded seam. During continuous welding, the welded seam with slag travels along the spiral path, and the rough bead lifts the block up the bore of the tube until the wt. of 80 kg causes the block to fall and its edge scrapes away the slag. Tubes welded in this way have a clean bore, free from slag.
