Title: Microwave oven control
Inventor: NODA TOMIMITSU
IPC: H05B6/68
Filed: 1991-03-18
Abstract: A cooking period in a microwave oven is terminated when the detected temperature 6 of exhaust gases shows significant fluctuations. These fluctuations are indicative of the end point of cooking when large quantities of water vapour are produced. An amplifier 7 filters out the steady increase in temperature due to progressive heating and comparator 16 compares the fluctuations with a threshold. A fan may cool the oven between cycles (fig 6), a second temperature sensor may be provided outside the exhaust stream (fig 8) to eliminate supply voltage variations, or has a different temperature response (fig 23) in order to detect the fluctuations. A radiant heater may also be provided (figs 9 and 28), a thermistor or silicon diode may constitute the temperature sensor, the system may selectably respond to long term temperature change during cooking (fig 16) and changes in supply voltage causing fluctuations in temperature signal can be ignored (fig 20). A warning may be given if the oven is in a cooling phase. <IMAGE>

Title: Twin bottle clinical suction apparatus
Inventor: EAST DONALD
IPC: A61M1/00
Filed: 1991-12-07
Abstract: In a body fluid collection system, a motorised changeover assembly automatically transfers the suction S and patient P connecting ports from a first suction bottle to a standby bottle at timed intervals. Release of the vacuum during transfer, causes the potentially dangerous aerosols in the bottle to subside. A liquid level sensor in each bottle monitors the full state and gives a visible and audible warning to change the full bottle for a fresh one. If both bottles reach the full state, both the suction and the patient ports are closed and a continuous audible and visual warning is given for urgent attention. A single rotatable valve body having suitable through-channels is driven by motor M to switch the suction and patient ports simultaneously (fig 2). Bleed channels (4, 5) are provided to release the vacuum. The timer circuit is variable to allow cycle times between 5 and 15 minutes. <IMAGE>
