Abstract: A portable hand held and manually operated label printer and a method of its use in transferring information from a master plate onto a pressure sensitive label. The printer consists of a magazine section wherein a continuous roll of serially linked pressure sensitive labels are installed with the roll end thereof threaded through an appropriate passage into a manually operated label receiving and printing group. A printing roller arranged on a spring biased slide within the label receiving and printing group, is manually displaced to travel over one of the pressure sensitive labels, sandwiching it against a master plate, transferring raised characters formed on the master plate into the label.

Abstract: A composite identification band having multiple identification indicia, the assembly of which comprises a strap with a lower pocket overlying an upper or exposed surface and opening at one end to receive a pressure-adhesive or any other type label adapted to have writing thereon; an upper pocket superimposed on said lower pocket and opening at both ends to receive and store an encoded identification plate. The upper surface of the upper pocket is partially folded back over a portion of said upper surface to form a pocket adapted to receive one or more pressure-adhesive indicia labels. An additional pocket, adapted to receive other indicia, is spaced in longitudinal alignment adjacent to said upper and lower pockets along the strap, an end of the strap nearest the upper and lower pockets contains a stud projecting upwardly from the underside and through the band.

Abstract: Method and apparatus for filtering and permanently separating the serum fraction from the cell fraction of centrifuged blood and the like. A separator head is passed through the serum and is positioned at the interface of the serum and the heavier red cells. As the separator head is positioned serum passes through a self-sealing passage in the separator head and into a collection tube that positions the separator head. Upon withdrawal of the collection tube the passage in the separator head closes sufficiently to effectively block the passage and the serum can be poured from the collection tube. The collection tube can be reinserted to pour off measured volumes of the serum.
