Abstract: Afluid coupling, e.g. a variable speed fluid coupling has a primary rotor (1) and secondary rotor (2) which are free to rotate independently of each other within a housing (7). The primary rotor (1) together with the housing (7) are adapted to pump fluid from the housing (7) through channel (15) to a reservoir (10) and from reservoir (10) to the working circuit between rotors (1 and 2) via channel (14) and feed ports (20). The fluid holding capacity of the reservoir (10) can be varied and its contents transfered in full or in part to the working circuitry of the rotors (1 and 2). When charged with fluid rotors (1 and 2) produce a hydro-kinetic coupling of variable output speed determined by the amount of fluid circulating between them and apportioned by the volurrietric displacement offluid from the reservoir (10). Where no displacement of fluid from reservoir (10) occurs and no fluid is introduced to the working circuit of the rotors (1 and 2) a neutral coupling condition exists. A fluid pressure sensitive valve (16) acts under back pressure conditions caused by reducing the volumetric capacity of the reservoir (10) and diverts fluid under pumped influence through channel (17) to the working circuit of rotors (1 and 2).

Abstract: Un appareil pour brasser ou agiter un matériau fluide comprend un récipient allongé (1) qui contient le matériau, un dispositif (6, 7, 9. 10) qui transmet un mouvement d'oscillation longitudinale au matériau et une pluralité d'obstacles stationnaires (19, 35) montés sur la paroi intérieure (2) du récipient, les uns après les autres dans le sens de la longueur. Les obstacles présentent des pointes aiguës (20, 37) en arête, et chaque arête est orientée dans un sens (30) perpendiculaire à celui du mouvement d'oscillation. Chaque paire d'obstacles et l'extension intermédiaire de paroi intérieure définissent un espace concave (26) où le mouvement d'oscillation forme de façon répétée des tourbillons puis éjecte vigoureusement ces tourbillons hors de l'espace concave, en favorisant ainsi l'agitation du fluide. L'invention concerne particulièrement des récipients cylindriques pourvus d'obstacles annulaires (19) ou formés par les spires successives d'une spirale (35). Un mouvement longitudinal constant à travers le récipient peut être transmis au fluide, outre le mouvement d'oscillation; des dispositifs peuvent également être prévus pour introduire séparément deux fluides à une extrémité du récipient et pour les évacuer, à l'autre extrémité. Certaines conditions sont spécifiées et doivent être observées pour assurer l'uniformité de la durée du séjour du contenu fluide lorsque l'appareil est ainsi utilisé.

Abstract: A method for filling liquids, wherein a container is firstly filled with a gas-generating water or water by amount somewhat larger than a predetermined amount and is subsequently filled with an undiluted solution by means of injection, after which an excess portion of the gas-­generating water or water is removed from its upper stratum in the container, whereby a filling amount is made to agree with the predetermined amount. By the method of firstly filling the container with the gas-generating water or water and subsequently filling the container with the un­diluted solution, the gas-generating water or water is unsusceptible to mix with the undiluted solution. The final amount of product liquid is controlled by means of removing the gas-generating water or water filled firstly, whereby the accuracy in content or amount of liquid filled is improved.

Abstract: An ultrasonic motor in which elastic progressive waves are excited in a vibration member (4) which consists of a piezo-electric substance (1) and an elastic substance (2) and in which a rotary member placed on the vibration member (4) in contact therewith under the application of a pressure is driven by the frictional force. The vibration member (4) has a disc-like shape, and electrode groups (9, 10) provided for the piezo-electric substance (1) are arranged concentrically maintaining phases that are different in the circumferential direction in which the vibration proceeds. The electrode groups (9, 10) excite the vibration member (4) in a quadratic or higher flexural vibration mode in the radial direction and in a cubic or higher flexural vibration mode in the circumferential direction so as to produce an equal mechanical impedance as viewed from the electrode groups (9,10). Standing waves of flexural vibrations excited by the electrode groups (9, 10) are superposed, so that the flexural vibration proceeds in the circumferential direction to drive the motor.
