Abstract: In combination with a transport mechanism that includes a plurality of conveyor rollers, an apparatus is used to position a carriage loadable with a wound reel at a desired location on the transport mechanism. The apparatus includes a rotary pulse generator associated with one of the plural conveyor rollers for registering the revolutions of the one of the plural conveyor rollers wherein the revolutions embody a measure of the distance traveled on the transport mechanism by the carriage. The apparatus also includes at least a first and a second initiator for determining the current position of the carriage on the transport mechanism. The first initiator detects a first position of the carriage. The second initiator detects a second position of the carriage.

Abstract: Devices, systems and methods for treating a biological fluid are provided comprising placing the fluid in contact with a complement filter capable of depleting at least one complement fragment from the fluid while at least one component of the biological fluid is being stored.

Abstract: A method for processing a biological fluid comprises the steps of collecting platelet-rich plasma (PRP) in a container containing a complement filter, centrifuging the PRP in the container to provide a supernatant layer comprising a volume of platelet-poor plasma (PPP) and a sediment layer including concentrated platelets, passing most of the volume of the PPP from the container, suspending the platelets in the remaining volume of PPP to provide a platelet suspension and storing the platelet suspension in the container for a storage period of at least about 24 hours while contacting the complement filter with at least a portion of the platelet suspension and removing complement from the platelet suspension.

Abstract: A shutter panel for use in a lost formwork for making a cavity floor. The panel has connection members for bearer feet. The connection members extend through holes in the shuttering panel. For marginal reinforcement of the panel around the holes, special fittings are provided, for example bracing plates, flanges or washers disposed against the underside of the panel. The holes in the shutter panel may also have an inside diameter such that the bearer feet can be passed through them from above at the time of fixing to fittings at the holes. The panel preferably consists of plaster.
