Abstract:
Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.
Abstract:
An orbital shaker device (1) for biotechnological and/or biomedical applications comprises a frame (10), a platform (15) for receiving biotechnological and/or biomedical containers (50), eccentric couplings (13, 14) for allowing an orbital movement of the platform (15) relative to the frame (10), counterweight units (17, 18) for balancing the orbital movement, and at least one motor (19) for driving the eccentric couplings (13, 14). The device comprises two eccentric couplings (13, 14) arranged near respective opposite edges (27, 28) of the platform (15), while each counterweight unit (17, 18) is arranged approximately in the plane of the combined center of gravity of the platform (15) and the containers (50). Furthermore, both eccentric couplings (13, 14) are driven by the motor (19) or motors, either directly or indirectly. In this way, an optimal vibration compensation is achieved while allowing an imaging unit (40) to be mounted underneath the platform (15).
Abstract:
The device (10) comprises a substantially stationary outer frame (14) and a movable inner frame (18) supported by the outer frame (14) . The inner frame (18) is provided with a lower support plate (26) for a receptacle (C) containing the product to be mixed and with an upper clamping plate (30) which can be moved towards the inner plate (26) to clamp the receptacle (C) . The lower and upper plates (26, 30) are both rotatably mounted about a vertical axis (Z) . The device com¬ prises a first electric motor (32), first driving means (38, 40, 42, 44, 45) arranged to impart a vertical oscillation movement to the receptacle (C) and second driving means (38, 40, 42, 58, 60, 56, 54, 52, 48, 26) arranged to impart a ro¬ tational movement about a vertical axis (Z) to the receptacle (C) at the same time as the vertical oscillation movement. The first and second driving means are both operated by the first electric motor (32) .
Abstract:
The invention relates to a method for producing a mixed drink, wherein a capsule (22) enclosing a powder-filled volume (27) is inserted into a receptacle of a mixing device, and is opened by closing a lid of the receptacle, and as a result, a cover film (26) of the capsule (22) is pierced by several hollow needles (12, 14). To this end, pressure is exerted thereon by means of a punch (9), which causes the piercing of a closure film (25) above an outlet (24) via mixing rods (32) and via skewers (29) arranged in the volume (27). Water is then injected through a portion of the hollow needles (12), and the mixture is discharged through the outlet (24). After a pause or introduction of air under positive pressure by means of a further hollow needle (14), water is injected again, and finally, air is introduced once again. During the entire process, the receptacle is put into a vibration by an electric motor via an eccentric pin, the frequency of which is about 42 Hz, and the amplitude of which is about 1.5 mm, and which is transmitted onto the capsule (22). The result is an intensive mixing of the powder with the water.

A apparatus comprising: a vessel component comprising a flow-through interior chamber having an interior sidewall and an exterior sidewall; at least two inlets for introducing chemical components into the flow-through interior chamber; at least one outlet for removing product from the flow-through interior chamber; and an off center rotation component which is operatively connected to the vessel component. During operation of the apparatus, the off center rotation component generates vortical movement of at least two chemical components through the flow-through interior chamber of the vessel, and converts at least a portion of the at least two chemical components to at least one reaction product or product mixture. A method of using the apparatus to produce reaction products or product mixtures. The apparatus and method are useful for producing specially chemicals such as fragrance and flavor compounds, insect pheromones, petrochemicals, pharmaceutical compounds, agrichemical compounds, and the like.
Abstract:
A method for mixing fluids and/or solids in a manner that can be varied from maintaining the integrity of fragile molecular and biological materials in the mixing vessel to homogenizing heavy aggregate material by supplying large amounts of energy. Variation in the manner of mixing is accomplished using an electronic controller to generate signals to control the frequency and amplitude of the motor(s), which drive an unbalanced shaft assembly to produce a linear vibratory motion. The motor may be a servo motor, stepper motor, a linear motor or a DC continuous motor. By placing a sensor on the mixing vessel platform to provide feedback control of the mixing motor, the characteristics of agitation in the fluid or solid can be adjusted to optimize the degree of mixing and produce a high quality mixant.
Abstract:
The performance of a mixing machine for mixing paints and other fluid bodies is monitored by powering a mix drive and/or a clamp drive in accordance with a program. Torque applied by a motor that powers either of those drives while executing the program is monitored and the program may be modified accordingly. For example, mixing speed and mixing duration may be changed if the level of, or fluctuation of, torque applied by a mix motor suggests that the fluid body has characteristics, such as mass, for which the initially-selected mixing program is inappropriate. Similarly, torque applied by a clamp motor may be monitored to determine maintenance issues and to detect if a container carrying a fluid to be mixed is being crushed under clamping pressure.
Abstract:
Zur Herstellung eines Mischgetränks wird eine ein pulvergefülltes Volumen (27) umschliessende Kapsel (22) in eine Aufnahme einer Mischvorrichtung eingesetzt und geöffnet, indem ein Deckel der Aufnahme geschlossen und dadurch eine Deckfolie (26) der Kapsel (22) von mehreren Hohlnadeln (12, 14) durchstossen wird. Durch einen Stempel (9) wird dazu Druck auf sie ausgeübt, der über im Volumen (27) angeordnete Mischstäbe (32) und Spiesse (29) das Durchstossen einer Verschlussfolie (25) oberhalb eines Auslasses (24) bewirkt. Durch einen Teil der Hohlnadeln (12) wird nun Wasser eingespritzt und die Mischung durch den Auslass (24) abgeleitet. Nach einer Pause oder Einleiten von Luft unter Überdruck durch eine weitere Hohlnadel (14) wird nochmals Wasser eingespritzt und schliesslich nochmals Luft eingeleitet. Während des ganzen Vorgangs wird die Aufnahme durch einen Elektromotor über einen exzentrischen Stift in eine Vibration versetzt, deren Frequenz bei ca. 42Hz liegt und deren Amplitude ca. 1,5mm beträgt und auf die Kapsel (22) übertragen wird. Dadurch tritt eine intensive Vermischung des Pulvers mit dem Wasser ein.
