Abstract:
A developer supply container includes a rotating container for conveying a developer and an intermittent regulator for intermittently supplying gas into the rotating container and regulating an internal pressure of the rotating container. A fixed amount of gas is intermittently supplied by the intermittent regulator to the gas mixing space and is discharged from the powder discharging port after the fixed amount of gas is mixed with the developer. Since the intermittent regulator can periodically supply the fixed amount of gas to the gas mixing space, the fixed amount of gas ensures a stable gas pressure inside the developer supply container. The developer supply container can continuously and stably replenish the developer into the image forming device under any storage or operating environment. The air pressure of the developer supply container is maintained at a stable level and a high precision replenishment amount of the developer is achieved.
Abstract:
A hand operated device for storing, measuring, and dispensing powder or granular materials, with a simplified structure and reduced number of parts. The housing integrates a material storage container with a dispenser, comprising: special compartments and sound damper, made of elastic porous material that makes use of the device quiet; a one touch assembly and disassembly of an inner space of the device where the dispenser is located; structural elements for dispensing a predetermined volume of the material or its fraction, including a way to reduce the length of the working stroke of the dispensing mechanism; wall extensions to prevent bridges of sticky particles forming; separating walls to allow delivery a more than one material stored in one device including more than one material transporting mechanisms inside the dispenser; and structural elements providing exact measuring, and sifting or pouting of the materials.
Abstract:
The invention relates to a dosing dispenser having a dosing piston, for dosing formulations of a drug or nutritional supplement in the form of a free-flowing bulk material having a particle diameter in the range of 100-1000 μm.
Abstract:
The metering apparatus for the volumetric metering of pourable filler includes a housing and a metering slider which is movable relative to the housing. The housing and the slider conjointly define a metering chamber. The slider is configured as a vertical slider with a stroke axis. The housing includes a guide surface for the slider which extends in the direction of the stroke axis. The slider has a boundary surface corresponding to the guide surface and abuts in a sliding manner against the guide surface. A metering recess is introduced into the slider proceeding from the boundary surface and/or into the housing proceeding from the guide surface. With the slider in a stroke position wherein the metering recess is covered by the guide surface and/or by the boundary surface, the metering chamber is formed by the metering recess, the guide surface and/or the boundary surface.
Abstract:
A hermetically sealable dispenser for measuring and dispensing predetermined amounts of a granular product without breakage of the product. The dispenser comprises a container which can be filled with the product, and a flexible, rotatable, paddle wheel fixed within the container. The spacing between paddles of the paddle wheel form measuring compartments. The dimensions of the paddle wheel are such that the wheel forms a hermetic seal near one end of the container. A lid is provided to seal the upper end of the container such that the product is stored in an air-tight compartment prior to dispensing.
Abstract:
A metering device, for use in transferring a desired volumetric dose of a flowable substance from a storage chamber containing the flowable substance to a location outside the storage chamber, is disclosed. An outlet conduit is arranged between the storage chamber and the location to which the dose is to be transferred. The metering device is of such size and shape as to be able to pass through the outlet conduit and includes first and second end element which, when the metering device is located inside the outlet conduit, are in a sealing engagement with the inner walls of the outlet conduit. The shape of the metering device between the first and second end elements is such that a space of the desired dose volume is defined between the first and second end elements and the intervening section of the inner walls of the outlet conduit, in which space the flowable substance from the storage chamber may be enclosed. The metering device is of particular use in a dry powder inhaler.
Abstract:
The movable actuating lever is connected to a transmission lever, at one hand, and is guided by means of a pin within a guideway in the housing of the apparatus, on the other hand. The transmission lever serves at the same time for transmitting the actuating motion via further levers to the apparatus part to be actuated. Due to the position and the shape of the guiding groove and the lever, the course of motion of the actuating lever with respect to the fixed handle portion may be optimally adapted to technical and ergonomic requirements in order to achieve an effective force transmission having minimal frictional losses. Furthermore, no levers are in the way, and injuries are avoided.
Abstract:
A reciprocating gate valve for controlling the flow of particulate material is provided. The gate valve has a metal valve gate with an angled leading edge and also has a groove in the center of the angled leading edge. The valve body is formed from a metal cover plate that has a plurality of plastic body parts fixed to the cover plate so that the metal valve gate reciprocates between plastic body parts. The plastic body parts are preferably formed of self-lubricating plastic such as nylon or Teflon. The valve body has a rectangular recess which intersects the circular passage through the valve body with the rectangular recess having its long dimension positioned transverse to the direction of movement of the valve gate. The rectangular recess provides space for the particulate material to be moved ahead of the valve gate angled leading edge as the valve gate closes. The notch in the angled leading edge of the valve gate can sever any isolated piece of particulate material that is in a position to block the complete closure of the valve gate.
Abstract:
The ice dispenser 10 has disposed therein an ice bin 17 having an ice discharge port 17a at the bottom which can store a great volume of ice pieces. A fixed plate 29 having a plurality of openings 29a defined in one row not in vertical alignment with the ice discharge port 17a of the ice bin 17 is disposed below the ice bin 17. A measuring device 18 with a plurality of measuring sections, having predetermined dimensions and opening upward and downward, corresponding to the number of the openings 29a is disposed slidably between the ice bin 17 and the fixed plate 29. The ice pieces charged to the measuring sections 19 through the ice discharge port 17a are discharged therefrom and supplied to a plurality of glasses 12 positioned below the respective openings 29a by shifting the measuring device 18 so as to bring the measuring sections 19 immediately above the corresponding openings 29a.
Abstract:
A single dosage substance dispenser is disclosed, which includes a housing having a chamber formed therein for holding a substance to be dispensed and a discharge port that communicates with the chamber. A plunger is slidably mounted to the housing for extending through the chamber and into the discharge port. The plunger includes a first seal portion proximate a lower end thereof, a second seal portion disposed above the first seal portion and a receptacle portion located between the first and second seal portions for accommodating a single dosage of the substance to be dispensed. The first and second seal portions are sealably and slidably engageable with the discharge port. A spring is provided for urging the plunger to retract so that the first seal portion engages the discharge port and the receptacle portion is maintained in the chamber to collect the single dosage therefrom. The spring also permits the plunger to be advanced so that the second seal portion engages the discharge port and the receptacle portion is driven beyond the discharge port to dispense the single dosage collected from the chamber.
