Abstract: ABSTRACT       A multi-layer flexible article includes a first layer of natural rubber,  a second layer of natural rubber, polyurethane, poly(acrylamide/acrylic acid) and polyethylene oxide and a third layer of acrylic copolymer and fluorocarbon telomer resin.   The article is preferably a glove formed by the method of dipping a hand shaped mold into baths containing aqueous emulsions of the components  used  to  form  the  layers.    Gloves  manufactured according to the method are substantially wet-hand and dry-hand donnable as compared to powdered latex gloves of similar size. The finished  gloved  is  water  washed  and  wet  autoclaved  to substantially reduce the protein content from the natural rubber and  substantially  remove  other  water  extractable  allergenic moieties.    The  washing  and  autoclaving  renders  the  glove substantially  hypoallergenic  as  compared  to  gloves  not so treated.

Granted: 2000-12-12
Abstract: The present invention consists in a method of improving germination of seeds which comprises adding the seeds to a solid-form superabsorbent polymer that has absorbed water, and treating the seeds for control-led hydration for a time and at a temperature suffi-cient to cause the seeds to imbibe sufficient water to enhance resultant plant vigor but insufficient to cause seeds sprouting, while supplying an oxygen-containing gas to the seed-medium mixture.  In accordance with the present invention, solid medium particles will not remain adhering to the seeds, the seeds after hydration treatment can be dried with ease and, therefore, improved seeds capable of rapidly and uniformly germi-nating can be produced at low costs and on a commercial scale, without damaging the seeds.

Abstract: The e.g. aluminium alloy end-mountings (2A,2B) have sockets receiving the ends of a tubular e.g. glass-fibre former (1). Lathe-mounted, this assembly is rotatable about its longitudinal axis (4) and displaceable axially w.r.t. and extrusion head (14). Using a triangular cross-section die, the latter lays down a conical elastomeric grading ring (9) at the tube/mounting junction, consolidated by an inclined roller and scored axially (16). While the assembly moves axially, an inverted T-section die then extrudes on to the former a helix (20) of the same insulant, which incorporates a projecting helical rain-shed (18). A narrow roller (19) consolidates the material, expelling any air, which at the ends escapes via the scoring (16). The completed assembly is then cured.

Abstract: Light emitting rigid, fracturable projectile-type marking ammunition and an electronic strobe flash apparatus for use with air powered guns are provided.  The marking ammunition is in the form of a phosphorus paintball.  The electronic strobe flash apparatus comprises an exciter adaptable for use with paintball guns for exciting the phosphorus paintball to emit light.  The exciter couples to the muzzle of a paintball gun.          The light emitting paintball provides a luminous trail when discharged from the paintball gun.   A paintball according to the instant invention comprises a spherical pellet or capsule defining an interior chamber,  and a filler contained in the chamber.  In one embodiment, the capsule is impregnated with a phosphorescent  material.    In  an  alternative  embodiment,  a phosphorescent  material  is  mixed  with  the  filler. The phosphorus material  absorbs  light when  exposed  to  a  light source, and after the light source is removed, emits light.  A paintball   being  discharged from a paintball gun enters the exciter.   Upon detecting the presence of a paintball,  the exciter is triggered to produce a high intensity light.  Light is absorbed by the phosphorescent material.   After the light is removed, the phosphorus material continues to emit light.          Paintballs  according  to  the instant  invention  discharged through the exciter provide a luminous trail  and thus, may be used effectively in the dark.
