Abstract: The storage of blood and the prevention of coagulation are effected by diluting freshly drawn blood with either isotonic saline or isotonic saline including preservatives and subtherapeutic amounts of heparin. The present method of storing blood is especially useful for autotransfusion and storage of blood for subsequent fractionation or analysis of aliquots thereof.

Abstract: A rake for attachment to a tractor and operation by the tractor hydraulic system. Rake tines are carried on an endless chain by pivotally mounted brackets along upper and lower runs with counterbalance means providing pivotal movement of the tines between folded and extended positions while traveling along the upper and lower runs, respectively. The rake may be moved to extend laterally outward from the tractor for raking between trees, and the like. The mounting and guide means for the chain and teeth-carrying brackets provide a sturdy and efficient raking action while avoiding clogging as brush is removed.

Abstract: A receptacle for hand-picked fruit which is susceptible to damage by crushing or bruising. A conventional picking bag or bucket is provided with a removable liner which is preferably formed from a single, flat sheet of a closed-cell foam plastic material. The liner is bent to conform to the cylindrical configuration of the picking bag or bucket wherein it is inserted, and does not interfere with use in the normal manner of canvas picking bags which are adapted for fruit discharge through the bottom.

Abstract: Pollen is dispensed from a container through openings in a wall portion thereof by attaching the container to the end of a member which is manually movable by means of a handle at the end opposite the container. The member contacts a stop when moving in one direction, thereby agitating the pollen within the container so that it falls through the openings which are downwardly disposed when the handle is grasped.
