Disclosed herein is a blood collection assembly including an auxiliary sample pouch with a pass-through tube for filling the blood bag. The pass-through tube is the same diameter as the remaining tubing of the assembly and is frangible within the pouch so that the tubing can be placed in communication with the pouch.

A rear loader for refuse collection vehicles. The rear loader includes a housing with an opening through which refuse is deposited in a hopper. A movable packer plate in the housing moves in opposition to the bottom of the hopper to partially compress the material and subsequently to convey the material through a discharge opening into the body of the vehicle. The packer plate in the housing also cooperates with an ejector plate in the body to further compress the refuse contained within the bod...

Reduced gaseous pressure operated, liquid receptacle structure having an enclosure member and a bottom cover. The latter is provided with an interior sealing protuberance which seals against the inner wall of the enclosure member, such seal being increased upon the application of reduced pressure of the interior of the structure. A one-piece, fixed differential valve device is disposed in a vacuum port of the enclosure member to permit the passage of air therethrough, but not the passage of liqu...

The disclosure relates to an apparatus and a method for removing serum from the uppermost portions of a specimen tube of centrifuged blood, in which the blood serum is disposed in a liquid pool above settled-out cellular solid materials. More particularly, the invention is directed to an easily handleable, readily mailable, collection tube closed at both ends by "one-shot" valve structures comprising self-sealing elastomeric elements pierced by hollow needles. Additionally, at least the lower va...

A dust-collection head for use in a dust-collection system. The outer end of the head has a substantially C-shaped configuration with a substantially curved face formed therein. At least two curved, parallel slots extend generally along the length of the face. A plurality of flow directors are disposed within a chamber formed in the housing of the head. And the flow directors extend inwardly from the face to form a number of flow passages within the chamber for providing a substantially even cap...

A collection tube for collecting filamentary material, like glass strand or roving, into a wound package; the tube has apertured projections on its exterior surface for engagement with the interior layers of a package to inhibit movement of the package on the tube during formation of the package thereon.

A garbage collection apparatus that performs scavenging processing for specifying unused cell blocks from among a plurality of cell blocks, some of which can be reached from a specified root cell block via one of a set of trays. Each of the set of trays being specified by a second type address and holding a first type address, each of the plurality of cell blocks (a) being specified by a first type address and (b) including a plurality of cells that each hold one of a second type address and a n...

A method and apparatus for collection of dirt particles utilizes two fluid permeable filter media, one within the other, at least one of which is of porous flexible material. A dirty stream of fluid passes downstream through both filter media, after which the clean stream of fluid is discharged. The dirt collected on the upstream surface of the flexible bag is separated to fall downwardly by introducing against the downstream surface of the flexible bag sufficient fluid pressure to cause at leas...

A fee collection device for the collection and storage of parking fees at a self-service parking lot and comprising a fully enclosed housing having an upper collection compartment and a lower storage compartment therein, the said housing also comprising a front face panel having an array of louvered deposit slots therein in communication with the collection compartment for receiving fee deposits therethrough, the said collection compartment comprising an array of inclined collection subcompartme...

A system for collecting refuse is disclosed comprising a nonstop refuse collection vehicle which is provided with a refuse collection tray adapted for transferring refuse dumped therein to a storage enclosure. The vehicle is provided with means for actuating refuse containers causing them to dump their contents into the tray as the vehicle moves along a collection path.
