  • Patent number: 4657151
    Abstract: A container is disclosed having a semirigid or rigid outer shell and a co-extensive flexible inner liner which is weakly or temporarily adhered to the shell to permit more convenient manufacturing of the container, and yet is collapsible to permit dispensing of the contents without displacement air. The liner may be weakly adhered to the shell by a low tensile strength adhesive although natural adherence or static electric attraction may also be used. Alternatively, a degradable adhesive may be used which holds the liner and shell together during assembly, but weakens to a point below the threshold of release between the shell and liner prior to the time of use. The container is particularly useful as a nursing container for feeding infants.

  • Patent number: 4651741
    Abstract: Accurate in vivo measurement of blood oxygen saturation by fiberoptical means is made possible throughout a wide range of hematocrit or total hemoglobin values by using a single R/IR ratio I and calculating the SO.sub.2 value therefrom through the use of a second-order polynomial of the formSO.sub.2 =Ak.sup.2 I.sup.2 +BkI+Cin which A, B and C are hematocrit or total hemoglobin-dependent coefficients. These values may be contained in a lookup table accessed by a hematocrit or total hemoglobin value selection, and k is a purely multiplicative calibration constant which can be readily determined for any individual fiberoptic system.

  • Patent number: 4648430
    Abstract: A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected. The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period. In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system. A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period. The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.

  • Patent number: 4643713
    Abstract: A venous reservoir is provided in which a blood inlet (42) is located at an inlet end (70) of the container (48) which extends upwardly with a fast rise and for a sufficient distance to allow the blood entering the inlet to enter a large volume and to expand rapidly. The top (74) of the inlet end wall (70) of the container communicates with a vent outlet (46) whereby a sharp decrease in the velocity of the blood flow resulting from its rapid expansion provides buoyancy to air in the blood causing air bubbles to rise to the top of the container and be vented through the vent opening. A top wall (76) of the container extends from the vent opening and toward a blood outlet (44), with the top wall being curved in a manner to prevent the velocity of blood from increasing until the blood is substantially at the blood outlet.
