Title: Blending of fluid materials
IPC: B03B5/66
Filed: 1982-02-04
Abstract: Particulate material such as sand is classified in two or more classifying devices (13 and 15) which operate on the principle of "hindered settling" each to provide a coarse underflow fraction and a fine overflow fraction. A chosen blend 12 of the underflow fractions is provided by pneumatic control circuitry (Figures 2,5,6) (not shown) which actuates flow control means in the form of valves (14) and (16) to open, by amounts in accordance with a chosen blend ratio, only when there is sufficient material available for blending. The flow control means may be in the form of pumps actuated to control the flow of the respective underflow fractions, means being provided to dump the underflow fractions which are surplus to the blending requirements. <IMAGE>

Title: Bio-electrical signal monitoring
Inventor: MAYNARD DOUGLAS EDWARD
IPC: A61B5/04
Filed: 1982-03-24
Abstract: Bio-electrical signals, which may have energies which fluctuate over a wide range of amplitudes are applied to an asymmetric filter (a) whose output forms the input to (i) a low pass filter (b) and (ii) a first amplitude compression network (C1). The output of the low pass filter (b) forms the input to a second amplitude compression network (C2). The microprocessor controlled switch (d) selects the output from C1 or the output from C2 as the input to an analog to digital converter (e), which samples the signals at frequent regular intervals. The compressed signals are then integrated over both positive and negative half cycles and the integrated sums are added to different frequency bands to indicate the electrical activity therein. <IMAGE>
