摘要:
The present invention comprises a system and methodology for denitrification using constructed wetlands. The constructed wetlands of the present invention can be effectively applied as a wastewater point source treatment technology to any high total dissolved solids (e.g. sulfites and sulfates), carbon deficient wastewater stream for nitrate control. Pollutants are removed from the stream via a number of processes including plant uptake, volatilization, filtration and biological reduction. The present system and methodology offers an ability to reduce outflow stream nitrate concentrations in a cost-effective manner with minimal capital investment.

A data cartridge handling apparatus comprises a ring-shaped carousel (40) rotatably mounted within a housing (22). Cartridge-accommodating cells (52) are angularly arranged about the carousel between an inner periphery (48) and an outer periphery (50) of the carousel. A transducing drive (70) is mounted within the housing and outside the outer periphery. A motor (60) rotates the carousel to facilitate selective alignment of a selected cell (52S) with the drive (70) along a radial dimension (106) of the carousel. A picker (100, 200) is mounted within the housing at a point within the inner periphery of the carousel (40). The picker (100, 200) has a picker arm (104, 204). A distal end of the picker arm has a gripper (110, 210) which selectively engages and disengages a data cartridge (72). The picker arm linearly translates in the radial dimension for the purpose of moving an engaged data cartridge from the selected cell (52S) to a loading position of the drive (70), and conversely for unloading a data cartridge from the drive and withdrawing the same into the selected cell. The gripper comprises a thumb (112, 230). One of the gripper and the thumb is pivotally connected to the picker arm to allow the thumb to selective engage and disengage a feature (160) on the data cartridge. A trip member (150, 250) is mounted in the housing between the outer periphery of the carousel and the drive for actuating pivoting of the gripper, and thereby actuating the selective disengagement of the picker thumb with the feature on the data cartridge for loading of the data cartridge into the drive.

An automated cartridge library has an essentially rectangular library frame which includes a frame front wall (22) and a frame back wall (24), and a library door (30) provided on the frame front wall. A transport actuator and guide region (90) is provided within the frame, the transport actuator and guide region including both a guideway along which a cartridge transport assembly (92) reciprocates and an actuator (124) which causes the cartridge transport assembly to rotate from a first transport position to a second transport position. A library front section includes a cartridge magazine cavity (50) and a entry/exit port module (54). A library rear section includes a region for tape drives (60) and an auxiliary cartridge magazine (70). Cartridge magazines (64) are insertable into the cartridge magazine cavity when the library door is opened so that a reference surface of the cartridges face the transport actuator and guide region.
摘要:
A cartridge library comprises plural cells for accommodating therein a cartridge of information storage media and a tape drive which transduces information relative when a cartridge is loaded into the drive. A cartridge loader (also known as the cartridge transport assembly) is mounted to the drive assembly for picking a selected cartridge from one of the cells and for inserting the selected cartridge into a cartridge slot in the drive. The drive assembly is stationary but the cartridge loader is pivotal about the drive assembly, and particularly about a pivot axis which is parallel to a center line of the data cartridge when the data cartridge is inserted into the drive assembly. The drive assembly includes a toothed transport track engageable by the cartridge transport assembly for incremental pivotal motion of the cartridge transport assembly about the pivot axis. The library also has a wall connected to the library frame, the wall having a series of windows formed in predetermined relationship with the cells of the magazine. The windows are used to detect a status (e.g., presence, absence, misinsertion) of the data cartridge in the magazine. In addition, the series of windows are employed for detecting a position of the cartridge transport assembly about the pivot axis. The cartridge transport assembly comprises a carriage first section and a carriage second section which is translatable relative to the carriage first section. A pair of cartridge engagement arms are mounted to the carriage second section for selectively partially inserting the data cartridge into the drive assembly. The cartridge transport assembly further includes a secondary cartridge contact member (forming part of a “flipper assembly”) which operates in response to movement of the engagement arm to moves the selected cartridge from partial insertion to full insertion into the drive. Also, the secondary cartridge contact member serves as a stop surface when the cartridge is ejected from the drive.
摘要:
The present invention provides methods for treating milk products to reduce the bacteria and fat therein and/or to recover proteins therefrom. In particular, the present invention provides a method of treating a milk product comprising dynamically filtering the milk product (particularly skim milk or whey) through a filtration medium having a pore rating of about 0.1-1 .mu.m to produce a fat-depleted milk product permeate. The present invention also provides a method of concentrating a protein in a milk product comprising dynamically filtering the milk product through a filtration medium to form a protein-enriched retentate or a protein-enriched permeate. This method can be repeated with the protein-enriched fraction using filtration media of increasingly smaller pore ratings in order to recover particular proteins or combinations of proteins (from among many proteins in the milk product).
