Abstract: A static mixing nozzle used with a dispenser system thoroughly mixes one or more liquids. The static mixing nozzle has an insert having a housing with a plurality of baffles arranged in a staggered and alternating pattern throughout the passage. The baffles cause turbulence which mixes the liquid. Static mixing nozzles with different numbers of baffles may be used in the dispenser system to accommodate the different types of concentrates and syrups which may be used. The insert is removable and may be formed in parts which can be easily separated and cleaned. The insert has a ridge with an outer diameter greater than that of the nozzle, thus allowing the insert to be manually removed.

Abstract: A static mixing nozzle for use with a dispenser system to thoroughly mix one or more liquids. The static mixing nozzle has a passage with a plurality of baffles arranged in a staggered and alternating pattern throughout the passage. A liquid passing through the static mixing nozzle will strike the plurality of baffles, causing turbulence which mixes the liquid. The baffles prevent laminar flow through the passage. Static mixing nozzles with different numbers of baffles may be used in the dispenser system to accommodate the different types of concentrates and syrups which may be used. The static mixing nozzle may be formed as part of the nozzle or as an insert for the nozzle. The insert is removable and may be formed in parts which can be easily separated and cleaned. The static mixing nozzle does not require any mechanical mixing and operates under standard operating pressures for dispenser systems.

Abstract: A motion retarder particularly useful for regulating rotary movement of a shaft, for example, includes an inner and outer tension unit carried on a bolt shaped rod. Arcurate end segments of a pressure member of each unit are positioned in an opposing manner to define a pair of shaft holding spaces. A spring carried on the rod between the inner unit and a head portion of the rod may be advanced through a threaded connection between an end of the rod and a lock-type nut forming part of the outer unit. This advancement compresses the spring to force an inner friction surface of the unit pressure member end segments into engagement with an outer surface of a shaft positioned in the respective holding spaces. This engagement selectively inhibits inadvertent shaft movement to maintain the position of the shaft until shaft movement is desired.

Abstract: A hopper-type railroad car for transporting ballast used for roadbed restoration includes a set of bottom outlets for discharge of the ballast. Gate assembly units are installed over these outlets to provide regulation of the ballast discharge. Each unit has an inner and outer opening selectively covered by an arcuate shaped door. Each door is connected by linkage to an inner and outer door shaft carried concentrically by the unit. Selective rotation of either shaft moves the respective door to cover or uncover the unit openings to regulate ballast discharge.
