Abstract: According to some embodiments, an oscillating sprinkler system is provided that includes: a central tubular portion having at least one row of flexible nozzles; a cam plate located inside a peripheral wall of said central tubular member, said cam plate having a plurality of cam slots for adjusting positions of said flexible nozzles upon rotation of said cam plate within said peripheral wall; and said peripheral wall including a window via which an edge of said cam plate is observable during rotation of said cam plate such as to designate an extent of angular displacement of the nozzles based on the positioning of the cam plate within the window.

Abstract: A method for improving the wettability of a medical device is provided, the method comprising the steps of (a) providing a medical device formed from a monomer mixture comprising a hydrophilic monomer and a siloxy-containing monomer, (b) subjecting a surface of the medical device to a surface treatment, and (c) contacting the treated surface of the medical device with a wetting agent solution comprising a carboxylic acid-containing polymer or copolymer to form a carboxylic acid-containing polymeric or copolymeric layer on the treated surface of the medical device.

Abstract: A method for preventing or reducing interaction between a container and a polymeric article contained therein comprises oxidizing a surface of the polymeric article. The method is advantageously used to package ophthalmic devices in polymeric containers.

Abstract: A microtoner (C) and method for producing same (10) is presented. The microtoner (C) includes a blend of at least one polymer (P1, P2, . . . and PN) and at least one thermoplastic polymer (P1, P2, . . . and PN). The method (10) of producing microtoner (C) includes blending (12) the at least one polymer with the at least one thermoplastic polymer and with one or more pigments to thereby form a dry mix toner formulation (T). The toner formulation (T) is pulverized (18) by mechanical means into an unclassified particulate microtoner (U). The unclassified particulate microtoner is then classified to produce the microtoner (C).

Abstract: A method (10) for forming a microtoner (C) for use in the development of electrophotographic images includes blending at least one polymer (P1, P2, P3, . . . PN) with at least one thermoplastic polymer (P1, P2, P3, . . . PN) and with one or more pigments to thereby form a dry mix toner formulation (D). The dry mix toner formulation (D) is melt mixed to thereby form a melt mix toner formulation (M) which is pulverized into an unclassified intermediate toner mix (U). At least one surface treatment addenda material (X) is dry blended with the unclassified intermediate toner mix (U) to thereby produce a surface treated unclassified toner mix (S), which is then classified to produce a surface treated classified microtoner formulation (C) having an improved particle size distribution.

Abstract: An apparatus (10, 100) for reducing the particle size of a bulk particulate or powder material includes one or more first particle-size reducing stages (12, 120) and a final particle-size reducing stage (14, 140). The first particle-size reducing stage (12, 120) receives the bulk material and reduces the particle size thereof to an intermediate particle size. The final particle-size reducing stage (14, 140) receives the bulk material having the intermediate particle size and further reduces the particle size thereof from the intermediate particle size to a desired particle size.
