Abstract: A re-taping machine for re-packaging radial lead capacitors. The capacitors arrive taped to discrete strips, with gaps at some positions where defective capacitors have been removed. The machine advances the discrete strips through a capacitor removal station. There a single puller tool is reciprocated to remove successive capacitors by pulling them laterally free of the tape and strip. The puller tool is readily removable and replaceable by other puller tools adapted for different types of capacitors. The tool has a claw which enters the space between the radial leads and engages positively against either the head of the capacitor or against kinks formed in the leads. The tool is also formed with a capacitor restraining bar which rests against the leads to control the fall of the capacitor onto a continuous output strip which serves as the new packaging medium.

Abstract: A reservoir for the collection, purification, and storage of blood during surgical procedures which comprises a hollow blood storage casing having a hollow, perforated member within said casing extending from end-to-end thereof. Blood defoaming means and a filter are carried by the hollow member, so that the blood defoamer and filter are noncollapsible, and extend the entire length of the chamber within the casing, with one of the ports communicating with the interior of the hollow member, so that blood passes through the perforations of the hollow member and defoamer-filter means.

Abstract: A burette chamber is provided which includes a primary and a secondary compartment, a wall member separating the primary and secondary compartments with the wall member providing an opening for communication between the primary and secondary compartments. When the burette chamber is included in an intravenous solution administration set, the set can continuously administer IV solution to a patient as well as to allow intermittent administration of medicaments with return to the continuous administration of IV solution to the patient after completion of medicament administration.

Abstract: A blood collection system which comprises several blood compatible sealed bags connected together by blood compatible conduits. Means for separating cryoprecipitate from blood plasma are provided. This separation is made by a filtering means. The filtering means is positioned in the outlet of one of the bags of the system. After the blood cells have been removed by a prior step, the remaining blood plasma is collected in the bag which has the filtering means in the outlet. In this bag, the blood plasma is frozen and then slowly thawed. Factor VIII rich cryoprecipitate forms in this bag as part of the freezing and thawing process. As the plasma melts, it flows from the bag through the filtering means. The filtering means positioned in the outlet of the bag retains the cryoprecipitate. Thus, the separation of Factor VIII rich cryoprecipitate from the blood plasma is effected.

Abstract: A reservoir for use with blood oxygenation apparatus is described herein. A chamber separator within said reservoir defines, in the interior thereof, a primary chamber and a secondary chamber, with a flow channel, connecting the primary and secondary chambers. A plurality of intake and outlet ports communicate with the primary chamber. The reservoir may be connected to blood oxygenation apparatus via the intake and outlet ports, while the flow channel may be clamped to prevent fluid flow between the primary and the secondary chambers, when it is desired to reduce the blood volume in the reservoir.

A metal retaining clip of Z-shaped cross-section is positioned between the upper and lower arms. In use, a loop of tape strip has one end thereof fixedly held between the lower arm and the retaining clip, and the other end is fixedly held between the upper arm and the retaining clip.

Abstract: One part by weight of streptokinase is chemically bonded to one to five hundred parts by weight of a carbohydrate, to form a material which has improved stability compared with free streptokinase.

Abstract: Samples which are to be processed or analyzed in the laboratory are placed in small vials or cuvettes. Groups of cuvettes are placed in arcuate carriers, which are then mounted about the periphery of a rotator head. The rotator head has two selectable motions. It can rotate at a higher speed on a vertical axis for an automatically timed period, thereby subjecting the samples to mild centrifugal settling or sedimentation, or it can rotate at a lower speed about an inclined axis, thereby subjecting the sample to mild agitation or mixing.

Abstract: A calibrating fluid for automated instruments for blood cell counting and hemoglobin determination comprising a sterile solution of oxyhemoglobin or other derivative products of hemoglobin and containing latex particles.

Abstract: A vial and syringe connector assembly is provided for the sterile addition of fluid material to a sealed container having an injection-type access port. The assembly comprises a syringe connector which carries a hollow, injection needle having one pointed end for passing through such access port. The other needle end is blunt. An open mouthed vial for the fluid material has an elastomeric sealing piston disposed in the vial mouth and movable in sealing relation axially of the vial. A bore is also defined axially in the sealing piston of a size to receive the blunt end of the needle. An elastomeric diaphragm which is integral with the sealing piston occludes the bore. The vial and sealing piston are carried on the syringe connector with the blunt needle end positioned in the bore. The blunt needle end is used to rupture the diaphragm for fluid flow through the needle of the contents of the vial without accidental "coring" of the diaphragm and consequent obstruction of flow through the needle.

Abstract: An improved meat tenderizing system is provided in which a pair of oppositely positioned carriage assemblies, each carrying a number of needle manifolds, is operated to align injection needles with a carcass that is conveyed in a longitudinal path intermediate the carriage assemblies. At least some of the needles are pivotable so as to direct the injection needles into the carcass at a desirable angle.A metered amount of tenderizing solution is automatically fed to the needle manifolds when the needles enter the carcass. After the metered amount of solution has been injected, the needles are automatically withdrawn and the carcass is conveyed for further processing.

Abstract: A system and method is provided which has the general capabilities of measuring the speed of coagulation, congealing or solidification of a fluid sample, and which has particular utility in the measurement of the time required by a sample under test to increase viscosity to a particular level. The system and method to be described is predicated on a viscosity principle, and it includes a movable magnetic member suspended in the fluid sample and which changes position when the sample achieves a predetermined degree of viscosity. The change in position of the aforesaid member is photoelectrically or electromagnetically detected, and the time at which the change occurs, is used in the determination of the time required, for example, for the sample to form a fibrin clot, in a blood or plasma sample or to effect a particular reaction causing solidification or congealing of the sample.

Abstract: There is disclosed herein a method for collecting blood plasma in plastic bottles wherein the blood plasma can be stored for periods of time and can then be utilized in obtaining blood fractions therefrom. The method includes the concept of filling a previously sterilized and hermetically sealed bottle with blood plasma. The bottle, after filling, is sealed at the neck portion thereof by means of heat sealing. The portion of the bottle above the heat seal is severed. Thereafter, the filled bottle is frozen and transported to the site for use. The bottle containing the plasma is then thawed and conveyed to a plasma removing device. The plasma is removed by severing a portion of the bottom of the plastic bottle, thereby permitting the liquefied plasma to flow therefrom into a collection vat.
