摘要： A tobacco leaf mixture containing lighter and heavier fractions is fed into one side of a housing while an airstream flow is introduced at the other side of the housing and in an upwardly directed flow course so as to cause it to entrain the lighter fraction of the mixture therein, with the heavier fraction falling to the bottom of the housing. A suction lift is maintained at the top of the housing to increase the velocity of the lighter fraction containing air flow outwardly from the housing. The lighter fraction containing air flow is then delivered to a separator unit to recover the lighter fraction. The lighter fraction can, for example, be the laminae material from which shredded cigarette tobacco filler is made.

摘要： An improved apparatus and process for the operation of a down-flow granular medium bed filter is disclosed. A splash plate for dissipating the force of influent liquid is rotatably connected to support means, allowing the plate to rotate from a position parallel to the bed surface to a position perpendicular to the bed surface upon the liquid above the bed rising to a selected first level. The splash plate is maintained in the perpendicular position for the remainder of the filtration cycle, the backwash cycle and any chemical cleaning cycle, allowing unobstructed operation of the filter bed. The splash plate returns to the original position at the start of another filtration cycle.

The analogs have the formula: wherein Z comprises a nucleophilic group and optionally a protecting group; L is a linker; R1, R2, R3, R4, R5 are each independently H, a protecting group, or C1 to C6 alkyls, provided that R1 and R3 may form a six membered ring with the nitrogen and carbon atom to which R1 and R3 are attached; R6 and R7 are each independently H or C1 to C20 alkyls; and including salts thereof. The analogs are immobilized on latex particles and prepared for use in assays for lidocaine.

摘要： The present invention relates to immobilized procainamide analogs, as well as to a method of making immobilized procainamide analogs. These immobilized analogs are prepared by activating the carboxyl group on a substituted p-benzoic acid derivative toward nucleophilic attack; reacting the activated benzoic acid derivative with a polyamine to produce the benzoic acid derivative of Formula 3: and binding the benzoic acid derivative of Formula 3 to a latex polymer having functional groups that react with aliphatic amino groups. A method of conducting an immunoassay using the immobilized procainamide analog Formula 3 is described, comprising the steps of preparing a solution comprising said immobilized procainamide analog; adding a sample suspected of containing procainamide to said solution; adding an anti-procainamide antibody to said solution and observing the rate of increase in solution turbidity following antibody addition.

摘要： An improved method for maintaining a granular medium filter in a clean, operable condition is disclosed. The time interval required for the level of liquid above the filter bed to drain from a backwash outlet level to the upper bed surface level following a backwash cycle is monitored. Upon this measured draindown time exceeding a predetermined interval of time, a chemical cleaning cycle is initiated for the granular medium bed filter.
