Title: Driving device for a vortex mixing apparatus.
Inventor: HALL RICHARD CHARLES
IPC: B01F11/00
Filed: 1990-09-07
Abstract: A driving device for a vortex mixing apparatus comprises holders for holding a mixing unit of a type having at each opposite end a pumping diaphragm for imposing a pulsatile flow on a liquid passing through a primary channel in the unit. Two pistons are each arranged to cooperate with a respective one of the diaphragms and to reciprocate between a retracted position clear of the unit and an extended position in which it extends into a housing of the unit and compresses the respective diaphragm. Driving mechanisms are normally arranged to reciprocate the pistons in phase at the same frequency such that when one piston is moving from its retracted position to its extended position the other is moving from its extended position to its retracted position and vice versa. Control mechanisms are arranged, upon stopping of the driving mechanisms, to cause both pistons to adopt retracted positions so that the unit may be inserted into, and removed from the holders without interference from the pistons.

Abstract: L'invention concerne des piles rechargeables en bioxyde de manganèse (en général des piles alcalines ayant des anodes de zinc ou des piles ayant des anodes en lithium et en un électrolyte non aqueux), notamment les cathodes de ces piles. Ces cathodes ne sont pas renfermées, en d'autres termes, aucune cage n'est agencée dans la pile entre les cathodes et les anodes. Des changements significatifs des dimensions de la cathode lors de la décharge de la pile sont évitées, alors que celle-ci a une tendance à gonfler pendant la décharge et à se contracter pendant un cycle de chargement. La cathode remplit essentiellement tout l'espace qui lui est réservé dans la pile, avec un léger jeu qui permet à la cathode de piles du type à bobine de se dilater en hauteur ou dans le sens longitudinal, ou de se dilater ou augmenter transversalement dans des piles de type à bouton. Des additifs peuvent être ajoutés au mélange cathodique, y compris notamment des fibres conductrices en graphite ou en d'autres matériaux conducteurs. D'autres matériaux peuvent également être ajoutés au mélange cathodique, y compris des additifs métalliques. L'invention concerne également des procédés de fabrication, y compris le compactage et le recompactage du granule cathodique, ainsi que toute une plage de pressions de compactage. Les piles ainsi obtenues peuvent avoir des taux de décharge élevés et supportent un grand nombre de cycles de charge/décharge.

     Preferably for light load said one inlet valve closes during the induction stroke and the other inlet valve opens and closes during the compression stroke. For full load said one inlet valve closes during the compression stroke, whilst the other inlet valve opens and closes during the induction stroke, so that both inlet valves are open together during induction.

Abstract: A modulator circuit for a betatron includes an independent low voltage D.C. power supply, an intermediate low voltage capacitor connected to one side of the betatron winding, and a high voltage capacitor connected to the other side of the betatron winding. Unidirectional current devices normally permit current flow from the voltage capacitor, through the betatron winding to the high voltage capacitor. Energy is thereby transferred from the power supply and low voltage capacitor through the betatron winding to the high voltage capacitor. Switches are provided selectively to reverse the direction of current flow and thereby discharge the energy stored in both capacitors into the betatron winding to excite the betatron magnetic circuit. Upon discharge of the high voltage capacitor, the unidirectional current devices once again restore normal current flow, so that the energy stored in the betatron electromagnet is returned to the high voltage capacitor. Repetition of this charging/discharging/recovery cycle pumps up the charge on the high voltage capacitor and multiplies the voltage.
