This invention discloses methods for producing modified cellulose, modified nanocellulose, modified nanocellulose functionalized with other functional species, and derivatives thereof. The present invention also provides cellulose, nanocellulose, and their derivatives that are safe to use inside an animal or human body and are biocompatible without costly purification. These cellulose or nanocellulose materials can be used in many different applications, including carrier for pharmaceutical active agents and other medical devices.

The vibration device includes a base, a movable bench, a first horizontal excitation unit, a second horizontal excitation unit, and a vertical excitation unit. The vibration device includes a first middle bench and a second middle bench between the base and the movable bench. The vibration device includes first horizontal elastic support units, second horizontal elastic support units, and vertical elastic support units that elastically connect the base, the first middle bench, the second middle bench, and the movable bench sequentially in the first horizontal direction, the second horizontal direction, and the vertical direction. If overall device is supposed as a first mass body, a second mass body, and a third mass body with the first horizontal elastic support units and the second horizontal elastic support units as boundaries, respective barycentric positions of these mass bodies are almost the same in the vertical direction and horizontal direction.

The invention relates to a vibratory floor made up of shaker modules protected against the entry of dust, and capable of emptying cohesive products. The inner volume (10) of each module is connected by means of a pipe (14) to an air or clean gas volume (19). Each module past the first row is provided with an anti-pressure device (46) made up of an anti-pressure plate (47) situated above the motor cover (44), supported by two flanges (48) and (49) resting on stationary parts (36) on either side of the module. The modules thus formed are protected against the entry of dust, and effectively emptying any cohesive product from silos, vessels, railroad cars or any other containers, without human or mechanized intervention.

A differential impulse conveyor system including detectable markers disposed in a series on a moving component of the conveyor system. A stationary sensor disposed in close proximity to the markers generates a signal when the moving component is in a first range of motion to dispose the markers proximal to the sensor, and the sensor either fails to generate a signal when the moving component is not within the first range of motion. The sensor signal causes a current conditioning device to condition current from a current source to operate a motor to power the conveyor tray at a first rate of acceleration in a first mode, and the lack of the signal causes the current conditioning device to operate the motor to power the conveyor tray at a second rate of acceleration in a second mode. Markers may be positionable to optimize the timing of the current modes.

A conveyor for separating, singulating or conveying bulk material comprises a conveying plate, a substructure and a pulse generator for generating an oscillation. The substructure stands on a base surface. The conveying plate is arranged on the substructure at a distance from the base surface. The pulse generator is fixed on the substructure and is/can be brought into an operative connection with the conveying plate. The oscillation generated by the pulse generator can be transmitted to the conveying plate and a force is exerted on the substructure by the oscillation. The conveyor comprises an equalising pulse generator which is fixed on the substructure and creates a counter-oscillation. A counter-force which is in an opposite direction to the force is exerted on the substructure by the counter-oscillation. A resultant force which results from the force and the counter-force and which acts on the substructure is reduced by the counter-force.
