Patent EP-0086393-B1 (EP)
IPC: F16H25/04
Filed: 1983-02-01
Granted: 1987-05-06
Abstract: A method and apparatus for minimizing backlash and improving the efficiency of speed reduction mechanisms in which a series of rollers are equally spaced in a circle on a disk to perform operationally somewhat like an internal ring gear. Mounted for eccentric movement and simultaneously engaging each of the rollers is an orbital rotor having a perimeter defined by an epitrichoid curve with a numer of lobes equal to one less than the number of rollers. The rotor is mounted for free rotation on an eccentric keyed to a drive shaft. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes on the rotor. A similar structure may serve as a second stage with a second orbital rotor driven by the first rotor and moved orbitally by the same eccentric. In carrying out the method of this invention, each of the rollers is individually adjusted to bring it into engagement with the rotor under controlled pressure and compliance. Each roller is mounted for controlled omnidirectional compliance and preloaded to provide an controlled pressure between each roller and the adjacent surface of the rotor. The outer surface of each roller is crowned to increase the efficiency and prevent binding that might be caused by angular deflection of the roller.Each roller is mounted on a shaft that is pressfitted into an eccentric bore in a mounting sleeve that is enlarged near the roller to provide for controlled deflection of the shaft as the sleeve is rotated in its mounting. Each roller is individually adjusted to produce a controlled preload pressure between the roller and the rotor.

Abstract: An apparatus as disclosed for controlling the distribution of fibers in a fiber felt forming process, which comprises a guide duct through which a gas current with felt fibers entrained is directed. The gas passes through a perforated conveyor, which retains the fibers. The duct is caused to oscillate by a connecting rod affixed to the guide duct and a rotary element by universal joints at either end, connection being effected by cardans, by which the rotary element entrains the connecting rod in its rotary movement. By moving the axis of rotation of the rotary element away from the center of the guide duct/connecting rod joint, an oscillating movement is imparted to the guide duct. The entire apparatus, including a motor for inducing rotary movement may be caused to undergo translational movement by a pair of opposed hydraulic jacks, the operation of which may alter the median direction of the movement of the oscillating guide duct. The apparatus as disclosed provides for automated movement and correction during operation of the device, providing better control over the distribution of fibers.

Abstract: L-malic acid is separated by means of electrodialysis from reaction mixtures derived from biotechnical conversion of fumarate into L-malate. Fumaric acid present in the acid concentrate from the dialysis is separated from L-malic acid without precipitation reactions using stepwise crystallization. Crystallized L-malic acid is produced in high purity and large yield. The alkali concentrate obtained during electrodialysis is recycled back into the biotechnical conversion. The process operates without appreciable losses of valuable materials and is very economical.

Abstract: Une alimentation de puissance multisources utilisant des convertisseurs haut rendement à découpage direct du réseau 220V 50 Hz fonctionnant à une fréquence de 20 KHz. Cette alimentation génère les basses tensions (9, 10, 11) nécessaires aux périphériques de commande et de gestion, et les hautes tensions (22, 23) programmables à distance (33) pour l'alimentation des cellules plasma. Toutes les sorties sont protégées contre les surcharges (15, 12) et les surtensions (16, 18, 31). A la mise en marche (21), l'apparition des hautes tensions est retardée par rapport aux basses tensions; à la coupure, les basses tensions sont maintenues momentanément après la disparition des hautes tensions. Les bornes de sortie hautes tensions sont isolées du réseau par des dispositifs électroniques à couplage optique (30). Le principe de découpage adopté et le choix de composants spécialisés (12, 14, 28) procurent à cette alimentation, des performances de rendement et de sécurité supérieure à celle des alimentations à régulation série généralement utilisées.
