A cam assembly having a solid cylindrical with a near end and a distal end and an opening extending from the near end through the distal end, wherein the opening is circular in configuration and has an inset, the near end is configured at a slight angle of less than about 15 from the vertical, and the opening extending from the near end through the distal end is angled through the cam assembly, the opening beginning at the near end and near a bottom edge of the solid cylinder and terminating through the distal end near a top edge of the solid cylinder.

A linear actuator member applies a vertical force to a vessel or to a holding apparatus in which a vessel is contained. A linear to angular motion constraining member such as a cage structure having a helical track translates linearly directed force and motion applied by the linear actuator member into a combined linear and rotational motion of the vessel. The combined vertical and rotational motion of the vessel in response to the vertical force is repeatable according to a predefined agitation pattern for mixing components in the vessel.

A cold brew coffee extraction device for adjusting the sonic vibration based on the sound signal includes: a current support extended in one direction and configured to apply an alternating current in a tangential direction of an outer peripheral portion; a magnetic vibrator accommodating one end of the current support therein, and configured to generate a magnetic field in a direction of crossing over the current support to be vibrated in a longitudinal direction of the current support due to a change in a polarity of the alternating current; a plate coupled to the magnetic vibrator to transmit the vibration to a fluid including a particulate matter; and a vibration adjustment circuit configured to, in a first mode, adjust the vibration only based on setting information inputted through a user interface, and in a second mode, to adjust the vibration based on the setting information and an external sound source.

The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

A culture bag includes a culture portion which has a culture space configured to contain and culture a culture fluid. The culture space is an endless circumferential circulation space in which the culture fluid can circumferentially circulate. The culture fluid can continue to circumferentially circulate in one direction in the endless culture space. This suppresses complexification of flow of the culture fluid. As a result, bubbles can be suppressed from generating without decreasing culture efficiency.

Apparatus to deliver predetermined forces, containers to hold particulate material and media, media, and the associated parameters for operating such equipment along with methods and compositions provided by the apparatus and methods.

The techniques described herein provide, in one embodiment, a rapid-agitation mixer for food products that comprises a product holder configured to hold a sealed product cup containing a food product to be mixed, and a drive shaft along an agitation axis, the drive shaft configured to secure the product holder and product cup in place. The illustrative mixer also comprises a drive motor configured to reciprocate the drive shaft in opposing directions, where the product holder correspondingly reciprocates the product cup to churn the food product within the product cup.

Aspects of this disclosure relate to a vessel support apparatus and to uses of the vessel support, such as in the laboratory setting. Apparatus of this disclosure may secure a vessel thereto, such as when the apparatus is in operation or use. Vessel support apparatus will comprise a vessel supporting means and one or more means for securing the vessel to the supporting means.

Device for shaking, within a rigid container, a powder and liquid, for conducting a test on the shaken content, includes: a frame; a first plate assembled thereto; a second plate assembled indirectly to the frame, arranged close to the first plate and movable relative to the frame and first plate; and a drive unit for moving the second plate relative to the frame and first plate. The container is carried by the second plate and is movably mounted relative thereto; the first plate includes a stop fixedly mounted on the first plate; and the second plate is moved relative to the first plate by the drive unit, in an alternating and periodic translational and/or rotational motion between a proximal position and a distal position, to move the container relative to the second plate and cause a series of impacts between the container and the stop to achieve a non-periodic shaking.

A shaking device for a fully-automatic instant check meter, which is used for shaking blood in a test tube uniformly. The shaking device comprises a frame body, a barcode printer, a first bracket, a second bracket, a rotating mechanism, a vacuum blood vessel shaking mechanism and a peripheral blood vessel shaking mechanism, wherein a first sliding rail, a first motor and a second motor are provided on the frame body; the rotating mechanism is connected to the first sliding rail in a sliding manner via a first sliding block and is connected to the first motor via a first synchronous belt; the vacuum blood vessel shaking mechanism is connected to the first sliding rail in a sliding manner via a second sliding block and is connected to a second motor via a second synchronous belt; the peripheral vessel shaking mechanism is arranged below the vacuum blood vessel shaking mechanism; and the barcode printer is arranged at one side of the frame body. The shaking device has a simple structure and a good shaking effect, and is safe and reliable.
