Abstract: 1357635 Lung ventilators MEDICOR MUVEK 14 May 1971 [18 May 1970] 15057/71 Heading A5T A pneumatic pressure respirator comprises a control unit 12 and an actuator unit 14 connected to the control unit by pneumatic valves 96 and 98 which are controlled by a pressure sensitive means 66 in the control unit and a pressure sensitive means 82 in the actuator unit. Oxygen is supplied from a high pressure cylinder 28 to pressure line 38, in the control unit 12 and pressure lines 106 in the actuator unit 14. In the control unit the oxygen flows through a pressure line 38 to negators 44, 46, 52 an OR-gate 42 and a memory 48. The pressure sensitive means in the actuator unit measures the pressure in the lungs 108 and has a pointer 80 having a fly 78 which can interrupt the flow of oxygen to two negators 44, 50. Air flow to the third negator 46 is controlled by a fly 62 on a pointer 64 of the pressure sensitive means 66 in the control unit. Flow of air to the pneumatic valves 96, 98 is controlled by a fourth negator 52 and the memory 48. One pneumatic valve 98 causes inspiration by operating a shut-off valve 102 which controls oxygen flow to the lungs 108 through a humidifier 115. The second pneumatic valve 96 causes expiration through a shut-off valve 100 and a pipe 104 which leads to the atmosphere 30. The gas pressure in the line 54 leading to the second pneumatic valve 96 controls the pressure sensitive means 66 and the oxygen passes to the atmosphere 30 through a shut-off valve 86 controlled by a pneumatic valve 88. A separate source of highpressure gas e.g. nitrogen may be used to run the control unit 12. In a second embodiment Fig. 3 (not shown) receiver nozzles 70 and 74 are dispensed with and outlets (70') and (74') are employed with the flap (124) of the pointer (80) moving therebetween.

Abstract: 1355216 Particle analysis COULTER ELECTRONICS Ltd 7 April 1972 [9 April 1971 12 May 1971] 16164/72 Heading H3P [Also in Division G1]  An axial trajectory sensor for a Coulter type particle analyser monitors the pulse width at three heights, e.g. 25%, 50% and 75% of peak amplitude, and passes on only pulses matching the standard requirements. The techniques used are similar to those described in Specification 1,355,215 (which measured only the "50% width"), viz the pulse is stretched and attenuated to provide the "fractional height" thresholds on which the pulse (delayed in another channel) sits. The resultant time-width signals are integrated to give a ramp and plateau form. The amplitude of the plateaus may then be tested in one of three ways:  Fig. 4 (not shown); separate memory stores (70) for the widths of the preceding pulse at each fractional height provide reference inputs to comparators (68-U) with attenuators (72) feeding comparators (68-L) to provide a tolerance band. Fig. 7 (not shown) uses a minimum duration memory circuit as in Specification 1,355,215 for the 25% reference which is attenuated for the other two reference levels. Fig. 8 (not shown) provides a simpler circuit, without a memory store, which tests for shape only, assuming that the width of every pulse will be acceptable at 25% height and this signal is suitably attenuated to provide 50% and 75% reference values.
