  • Patent number: 4774985
    Abstract: A process and apparatus for filling a generally tubular autmotive silencer casing with glass fibres are characterized by the feature of filling the casing from both ends simultaneously, preferably with the aid of spacer elements temporarily located on the ends of the casing during the filling step, any overflow of fibres into these elements being subsequently pushed into the casing to give a uniform density fill prior to installing end caps. The process/apparatus preferably also features bulking of the fibres by passing them through a specific jet configuration more than one of which may be used at each filling station.

  • Patent number: 4660608
    Abstract: Loading and solidifying of a cosmetic material is achieved by dripping a viscous cosmetic material into a container having a filter bottom, interposing a liquid absorbent membrance between the container and a presser, compressing the cosmetic material by the presser with the membrance interposed therebetween, and squeezing a solvent from the cosmetic material through the filter during such compression. A supporting block holds the container in position for it to be subjected to vacuum suction. The presser includes inner and outer pressing blocks and drives for moving the pressing blocks. The inner block is capable of fitting into the container to compress the cosmetic material, while the outer block abuts against the upper rim of the container.

  • Patent number: 4648432
    Abstract: An automatic bag filling machine employs a reduced pressure or a vacuum within a bag enclosing shroud to draw powdered material into either valved bags or vapor barrier bags in a series of increments to fill the bags with a relatively compacted powder. The shroud has movable liner assembly for adjustably enclosing bags of various size. A novel filling spout and a vapor barrier spout carrier by the shroud each have an expandable boot member to seal the mouth of the bag on the spout to preclude seepage of powdered material from the bag interior during filling. A filter tank connected to the machine reduces the discharge of powdered material into the surrounding atmosphere, and allows waste material to be reclaimed. Valves for controlling vacuum imparted to the shroud chamber, venting the bag interior, powdered material flow, and relief to atmospheric pressure of the shroud interior, are operated in proper sequence to fill the bag.

    Abstract: A process and apparatus for filling and packing a chromatographic column by the wet route in which a compression chamber is attached to one end of the column having an internal bore equal to the internal diameter of the column and aligned therewith to form a combined chamber, a fluid suspension of packing particles is introduced into the combined chamber and then a piston member is axially displaced within the compression chamber toward the chromatographic column to compact the packing particles in the column. The suspension liquid flows out of the column through a conduit formed through the piston and/or through the cap at the other end of the column. After compression, the compression chamber and piston are separated from the column and the packed column may then be attached to a chromatograph for use. Vibrators may be provided on the column or compression chamber to promote transverse rearrangement of the particles during compression.

The rotary units are above the path of the ports and remove excess beans from atop the ports. A compactor for the beans in the containers is provided along the path of the ports immediately downstream of the rotary unit, to eliminate voids between the beans and the beans on the turntable are carried to a second rotary unit which again propels the beans away from itself for ultimate removal through the ports.

    Abstract: When loading a cylindrical container with metal powder it is sometimes desirable to deposit the powder with the finer particles of the powder forming an outer layer surrounding the heavier coarser particles.To bring this about the powder is allowed to fall from the outlet of a reservoir in the form of a diverging continuous curtain of circular plan in horizontal cross-section. The axis of the curtain is arranged coaxial with that of the container so that the diverging curtain is directed against the inner wall of the container.The reservoir has a circular opening and a conical insert extends into the opening from the outside of the reservoir with the portion of the insert having the greatest diameter being positioned outside of the opening. The insert and the wall of the opening together define an annular passage which serves as the outlet of the reservoir.
