Abstract: A peristaltic pump equipped with a series of rollers eccentrically mounted upon a drive shaft, the pump also includes an elastomeric fluid delivery tube supported to extend in a direction parallel with the axis of the drive shaft. Each roller has a generally cylindrical outer surface equipped with a concentric annular rim that projects radially outwardly beyond the cylindrical surface and is rounded and smoothly tapered when viewed in longitudinal section. The rims of successive rollers are equally spaced and the rim diameter of each eccentric roller is sufficiently large to occlude a section of the tube when that roller is at its perigee with respect to the tube, at which time the adjacent cylindrical surface of the same roller also engages the tube but causes only limited non-occlusive deformation of that tube. The apparatus is particularly useful as a blood pump.

Abstract: A tubular conduit formed of resilient, flexible, thermoplastic material having an intermediate portion with at least one enlarged section that has a flow passage of substantially greater cross-sectional area, and a wall portion of lesser thickness and lower resistance to deformation, than found in the remainder of the conduit. The method of making the collapsible conduit, involving the steps of reshaping a preformed thermoplastic tube by molding it under heat and internal pressure, and the utilization of such a formed conduit in a linear peristaltic pump, are also disclosed.

Abstract: A new variety of Asiatic hybrid lily having large sized flowers of excellent form borne on a single stem in a compact raceme and particularly characterized by their unusual combination of yellow and gold color tones and by their widely spaced maculation, which extends across the base of the tepals, particularly the petals, from each side of the end portion of the nectary, providing a color pattern that is new in the upright Asiatic division of lilies. The flowers have a long persistence both on the plant and as cut-flowers and the plant itself is an excellent garden plant highly resistant to disease and showing high tolerance to virus. Its bulbs may be precooled and forced for cut-flower production and its flowers are produced in midseason, inbetween the flowering times of its siblings of similar appearance, so that it extends the season of cut-flower production.

Abstract: A new variety of hybrid lily plant particularly characterized by the rich orange color tone of its flowers and lack of spotting, as well as their unusually large size borne in large clusters of flowers having excellent form, strong color and long persistence, both on the plant and as cut flowers, these being features which are completely new in the upright Asiatic division of lilies suited to forcing and mass commercial cultivation. The new plant is highly resistant to disease and shows high tolerance of virus and is an excellent garden plant. Also, its bulbs may be precooled and forced for cut flower production, the clone being extremely vigorous and a good grower and propagator.
