A process of molding thermoplastic preforms into bottles and similar containers wherein pressurized liquids, such as water, are used in the stretching and shaping process instead of pneumatic gases, such as heated air. The result is greater control over the crystallization of the thermoplastic material and economies of scale. Addition of peroxides, or similar materials are used for sterilization can be added to the liquid thereby conditioning the container for immediate filling with sterile product and eliminating the need for an additional sterilization step following completion of the molding step. As an added step, dry, sterile air can be used to vent and dry the container just prior to introduction of product. Also use of liquid, rather than heated air, provides a washing or cleansing of actealdehydes or ethanol, which may be present in the extruded preform, from the finished container.

The invention provides a preparation method of virus-free seedlings of sweet potato. The method comprises the following steps: placing sweet potato blocks that are exposed under the sun and matured banana together for 3 to 5 days; planting the sweet potatoes in sandy soil to accelerate the germination in a culture box; setting relatively high temperature; picking 1-2cm top end of the seedling based on the length; cutting off the visual leaves; disinfecting the surface; rinsing with sterile water; picking off stem tip with 1 to 2 leaf primordium; inoculating to the corresponding culture medium to respectively induce differentiation of adventitious buds and generation of somatic embryogenesis; performing virus detection to a regeneration plant; performing subculture for the virus-free seedling; hardening-seedling; directly planting into a plastic greenhouse; performing flood irrigation with more water; preventing direct exposing under sun at noon in the first two weeks after transplanting; applying urea three weeks after transplanting; watering to obtain virus-free seedlings. According to the preparation method of the virus-free seedlings of sweet potato, the virus-free test-tube plantlets are acclimated and then directly planted into the plastic greenhouse, thus the survival rate is obviously raised, and the operation processes are decreased; the process of acclimating in an acclimating room is saved, and as a result, labor, materials and property are saved.

In a pre-filled Foley catheter for urine drainage, the conventional clip for releasing sterile water from a bulb (21) at the proximal end of the catheter, to fill the anchor bulb (20) at the distal end of the device, is replaced by a plug (25) which has an annular portion connected to a thin stem (27) by a circle of weakness. Snapping the stem (27) from the annulus provides a tactile signal through the opaque latex lumen that the catheter has been actuated. There is no separate clip to be disposed of. The interface between the latex and the plug remains undisturbed. Further improvement in the shelf-life and convenience of use of the catheter is delivered by the use of a sleeve, which can be of shrink-wrap material, around the bulb (21) and optionally also around the drain coupling (15) of the catheter. Apparatus for placing the plug and the sleeve is also described.
