Instrumented Rotary Tablet Machines II

Instrumentation of an Automatic Capsule-Filling Machine

“…Applied first to single-punch presses and later to high-speed rotary presses, this instrumentation has brought about great insights into the fundamentals of tablet compaction, facilitated product formulation, and permitted continuous in-process monitoring and control of tablet weight (1)(2)(3)(4).

Measurement of Lower Punch Pulldown Force and its Significance

“…Figure 3 shows the relationship of ejection force obtained during these trials for both high-and low-pressure settings. The higher ejection forces for the higher pressure settings have been reported previously (2). Thus, it can be expected both higher LPPF and ejection force will occur at higher compressive forces.…”

“…One-microliter volumes were injected into the chromatograph. A calibration curve was prepared by plotting concentration versus recorder response (IS background current) (2). The assay was thus calibrated from 0.2-1 .O Recovery from Blood-Known amounts of hexachlorophene in alcoholic solution, as in the calibration procedure, were added to 3 ml.…”

Powder Flow Studies IV

“…Woolley believed that serotonin was a key substance in any consideration of a biochemical etiology of schizophrenia, and it is true that all of the psychotomimetic indoles antagonize serotonin (3). Past criticisms of the use of serotonin inhibition as an index of LSD-like activity were based in part on the…”
