Abstract: The invention relates to a method for pneumatic treatment of powder materials in a recipient chamber (22), with introduction of two material streams into the above through two inlet tubes (40, 40a), optionally in a counter-current and/or approximately tangential sense and swirled in the recipient chamber (22). The material streams are for introduction at roughly the same level in the container and the tracks thereof are interleaved. The material streams are also introduced at an inclination angle (w) to a radial plane (E) of the recipient chamber (22) which is inclined downwards.

Abstract: The invention relates to a device for suctioning a powdery product. Said device comprises a auctioning tube (1,1?) which can be connected to a pneumatic suction transfer system and a clod-breaking device comprising a worm conveyor (4) which is rotationally driven by a motor (10) via a shaft (7). The worm conveyor is located at the end of the auctioning device in a truncated housing (3). The blades of the worm conveyor are provided with teeth and the shaft (7) is provided with knives (8) downstream from the worm conveyor (4). Any clods can be broken up by the worm conveyor (4) and the knives (8) complete the work of the worm conveyor by breaking up any clusters which move beyond the worm conveyor (4).

Abstract: An apparatus for decanting pulverulent product (Q) into a receptacle (50) made of deformable material which receptacle is arranged in a container made of rigid material and is temporarily placed upstream of a lock system containing so-called glove boxes, a shaft (64) is rotatably mounted at a distance (n) from an adjustable base (B), on which shaft at least one hood designed as a glove box, at least one hood trough (80) made of metallic material, preferably of stainless steel, is fixed; at least one support plate (78) for the rigid container is attached to length-adjustable piston/cylinder units (76) at an adjustable distance from the shaft (64), the support plate being parallel to the shaft longitudinal axis (N), and the rigid container is sealingly connected at the other end to a connecting tube (34a) which projects into the hood or the hood trough (80) or the hood system.

Abstract: A device for transferring a dusty, powdery, grain-like or granular conveyed material out of a storage receptacle and into a working or transfer receptacle or a similar accommodating space. The device comprises a working chamber, which is connected to a supply line for the conveyed material, and comprises a discharge cross-section. At least one feed line for a flow medium leads into the working chamber, and a filter device is located between the flow medium and the conveyed material. The supply line for the conveyed material leads into a tubular filter space, and a filter insert, which is also tubular and delimits said filter space, is placed inside the working chamber connected to an air line and/or to a gas line. In order to accommodate the filter insert, the working chamber contains a perforated inner tube that, with a housing, which delimits the working chamber, abuts against void.

Abstract: The invention concerns an installation for emptying casks (1) equipped with an external bag (11) and an internal bag (12) containing powdery products. It comprises a glove box (12) consisting of a bell made of a transparent material. It is provided, on its upper part, with an opening for the passage of a suction rod (3, 31, 32) equipped with sealing means between said pipe and the bell. The lower part of the bell is provided with means adapted to be urged in sealed position on the upper part of a cask (1). The bell (2) is suspended to a frame (5, 15) for its vertical displacement.

Abstract: An apparatus for pneumatically conveying powder substances in a pipe system, wherein a volume is sucked in with reduced pressure and discharged with increased pressure for being passed further along, characterized in that the apparatus has within the pipe system at least one metering chamber which can be alternately filled and emptied by way of control member for metering the powder substance.

Abstract: A device for the pneumatic conveyance of particulate substance having a specific gravity of 0.1 to 15.0 g/cm2 and a particle size of between 0.1 to 300 &mgr;m includes a flat plate like filter element between a pump chamber and sources of positive and negative pressure. The flat plate filter element provides a desired pressure drop and is cleaned of particulate material during operation of the device upon application of positive pressure.

Abstract: In an apparatus for the volumetric metering of fluid, pasty and/or powdery substances, in particular for separating small amounts of substance from a delivery flow, by means of an adjustable-volume measurement chamber which is connected to a feed conduit and which is provided with an outlet, a capillary measurement conduit (22) is connected as the measurement chamber to a vacuum conduit (33). In particular cases the measurement conduit can be acted upon by conveyor air, but in the normal case it is provided with a metering needle which is displaceable therein and whose free needle end (19) delimits the measurement chamber at one end. In addition a movable sealing body (56) is to be associated as a closure element with the mouth opening (23) of the measurement conduit (22), that serves as the outlet, which sealing body can be connected to a closure device (50) which is limitedly rotatable about a pivot means (52).

Abstract: Apparatus and process for transferring pulverent material from a supply container to a delivery point comprises an elongate exhaust pipe having a first end and a second end with a filter near the second end, an intake pipe extending from the supply container to the first end of the exhaust pipe and a transfer pipe extending from the first end of the exhaust pipe to the delivery point. With the first end of the exhaust pipe connected with the intake pipe, suction is applied to the second end of the exhaust pipe to draw pulverent material from the supply container to and through the intake pipe into the exhaust pipe where it is blocked by the filter. The first end of the exhaust pipe is then connected with the transfer pipe and air under pressure is supplied to the second end of the exhaust pipe to propel the pulverent material from the exhaust pipe to and through the transfer pipe to the delivery point and to clear the filter.

Abstract: This machine for washing containers of all open types is adapted to be enclosed in a compartment and comprises a tray to which the container is detachably secured; the tray is pivoted to a frame trunnioned in turn to fixed bracket bearings; a rotary brush connected to a supply of cleaning liquid is adapted, when the container is tilted to a position in which its bottom facing the rotary brush tip is somewhat higher than its opening and the tray is rotatably driven by a peripheral roller, to engage the bottom and inner side faces of the container. The brush and cleaning liquid supply means are responsive to cylinder means so arranged that the machine can accomodate a wide range of container sizes and shapes.
