Title: Disinfecting process - for respirators esp used in intensive care units
IPC: A61L2/20
Filed: 1970-10-12
Abstract: Appts. comprises an air and/or oxygen inlet system, an inspiratory pipe system, an expiratory pipe system and an element simulating the lungs, such as an expansible bag. The inlet system is connected to a device producing a bactericidal gas or vapour and the respirator is operated during the time necessary for its disinfection. Cross-infection inside a hospital can be avoided by the appts. which allows the respirators to be disinfected each time after use, the same cycle is followed by using an artificial lung. A bactericidal substance, such as formaldehyde, ozone, ethylene oxide, ethylene glycol etc. is produced in a gas-prodn. device and sent into the body of the respirator and then into the expansible bag, which it expands during the inspiratory phase. During expiration this same substance is sent back into the respirator and then to a discharge pipe which opens into a device for absorbing or destroying the substance. After disinfection, the respirator is rinsed with air and/or oxygen.

Title: Proportional action temp. controller - with sawtooth generator producing maximum and minimum changes of twice the supply voltage changes
Inventor: GONICHE ROBERT
IPC: G05D23/24
Filed: 1974-11-08
Abstract: A proportional-action temp. controller for a heating element in a flow of fluid is combined with a pulse generator which prodcues, when the temperature drops, a voltage greater that the voltage produced by a sawtooth voltage generator. The latter has a linear rise or fall of the sawtooth curve as a function of the time. The opposite branch of the sawtooth changes from or to zero in a short time compared with one period of a sawtooth oscillator. Maxima and minima are connected to the controller supply voltage in the same way and their relative change is twice the relative change of the electric voltage. Used for temperature control of haemodialysis baths. Errors are prevented in the final bath temp. which may be induced by fluctuations in the supply voltage or in the initial temp. of the fluid to be heated.
