Abstract: A bottle arrangement includes a bottle body a measuring bucket. The measuring bucket includes a guiding base assembly, a second compartment base, and a top cap. The guiding base assembly includes an inclined first compartment base, an inclined first channel base, an inclined second channel base, and an inclined backflow channel base. The guiding base assembly has a through first inlet opening, a through second inlet opening and a backflow opening. The first inlet opening and the backflow opening communicate with the bottle body. The measuring bucket also includes first through fourth partitioning walls provided on the guiding base assembly to define at least a first compartment, a first communicating channel, a second communicating channel, and a backflow channel.

Abstract: The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

Abstract: A container includes a quantifying device, an upper sealing cover and a container body. The quantifying device includes an external quantifying cup, a fixing portion and a fluid guide port. The quantifying device is disposed on an opening of the container through the fixing portion. Corresponding to a place above the opening of the container, the fluid guide port is disposed on an upper portion of the quantifying device, and a lower portion of the fluid guide port communicates with the container. The quantifying cup communicating with the fluid guide port is disposed on an outer side of the fluid guide port. The volume of a liquid fluid can be accurately measured and a non-metered original solution can be directly poured out, and the metering accuracy is improved during use.

Abstract: An overturning device for measuring and dispensing fluid and a bottle arrangement with the same, the overturning device includes a measuring bucket for using with a bottle body. The measuring bucket has a backflow channel, a first compartment, and a second compartment having an inlet opening, and a backflow opening. The first compartment is communicated with the inlet opening, wherein the backflow opening is communicated with the backflow channel, wherein the measuring bucket has a first state in which the fluid in the first compartment is capable of flowing into the second compartment, and a second state in which the fluid in the first compartment is not capable of flowing into the second compartment. The surplus fluid in the second compartment will flow back into the bottle body so that problem of accuracy and practicability of overturning device for measuring and dispensing fluid is solved.

Abstract: A dispenser for measuring and dispensing powder materials includes a slide housing having a powder inlet slot, a slide having a measure slot, and an elastic element. The slide is pressed against the slide housing by the elastic element to make the slide move relative to the slide housing. The slide moves between the first position and the second position. On the first position, the measure slot is in alignment with the powder inlet slot and the powder is filled into the measure slot; on the second position, the measure slot moves away from the powder inlet slot and the powder is discharged from the measure slot. The elastic element makes the slide press against the slide housing during moving to reduce the clearance between the slide and the slide housing, makes the slide move smoothly, and reduces the precision demand of manufacture and assembly.

Abstract: A rotary dosing device includes a rotating bucket, a container body, a cap top having an opening, a first restraining element, and a second restraining element. The rotating bucket has at least two partitioned dosing slots. The container body is rotatably coupled with the rotating bucket. The cap top is capped on the container body. The first restraining element is connected to both the container body and the rotating bucket for applying and removing restriction to movement between the container body and the rotating bucket in a packaging state and a using state respectively. By means of providing the first restraining element and the second restraining element, when the dosing device is not in use, the rotating bucket is prevented from rotating with respect to the container body and the opening is prevented from opening, so that the dosing device is convenient for packaging and transporting.

Abstract: This invention provides methods for treating diseases related to cerebral disturbances, such as drug addiction, obesity and epilepsy. A method for treating diseases related to cerebral disturbances comprises: (a) imaging the cerebrum of a patient, (b) identifying a locus of cerebral disturbance, and (c) irradiating the locus of cerebral disturbance with a therapeutically effective dose of electromagnetic radiation.

Abstract: The invention described herein solves the problem of keeping the target-to-skin dose ratio high while simplifying the complex structure of the source and the radiation beams; thus, lowering the cost of the radiotherapy device. Taught are radiotherapy devices for treating a patient having a treatment volume comprising a drum with a first axis of rotation and a housing for a radiation source with a second axis of rotation, the first axis of rotation and a second axis of rotation intersecting at various angles at a focus point (O).

Abstract: A dispenser for particulate material, includes a vessel for storing the particulate material, a dispensing head attached to or formed integrally with the vessel, the dispensing head having an port communicating with the vessel, a trigger movable with respect to the head and comprising a plurality of metering compartments that can be brought into alignment with the port upon depression of the trigger. The trigger has a number of steps formed thereon. A user-adjustable stopper is mounted upon the dispensing head and is configured to interact with the steps to selectively limit depression of the trigger to thereby align a selected one or more of said metering compartments with the port.
