Title: Respiratory device for aerosol mist or oxygen - with admixture of carbon dioxide to stimulate respiratory system
IPC: B05B7/30
Filed: 1974-04-17
Abstract: Respiratory device for an aerosol mist or oxygen-enriched air comprises an inlet tube for the primary air with an attached handle. A transparent, graduated flask contains the soln. to be sprayed. A mixer receives the primary air and the soln. is drawn from the flask and is atomised by the air inside the mixer. The outlet tube from the mixer leads to a "T" by which a tertiary gas, such as CO2, which stimulates the respiratory system, can be introduced through a valve. The mixture passes to a humidifier/heater vessel which is half filled with warm water to bring the temp. to that of the human body. Valves allow the patient to inspire the next mixt. and reject the expired gas to the atmos. through a filter, which may contain activated carbon. A mouthpiece is placed between the patient's lips but it may be replaced by a breathing mask applied over the mouth and nose. The fineness and regularity of the dispersion of the secondary prod., as well as regularity of its proportion, are considerably increased in the new device as compared with those in use hitherto.

Title: Drawing glass fibres from closely-spaced orifices - using inclined gas jets directed at the plate to remove flooding
IPC: C03B37/02
Filed: 1977-08-24
Abstract: An orifice plate having closely spaced orifices for glass fibre prodn. is brought into an operating mode by adjusting its temp. to that at which the glass has a viscosity of 1000 poises and allowing the glass to flood over the underside of the plate to form a matrix. Cooling gas is then directed onto the plate from multiple nozzles located along >=2 sides of the orifice area and located closely adjacent. The nozzles are inclined at 30 degrees-60 degrees to the plate and are so arranged that the gas flow impinges on the whole of the orifice area. The glass matrix is slowly withdrawn while raising the plate temp. and adjusting the gas flow so that fibre-forming cones develop at some at least of the orifices; the gas flow is then cyclically increased and decreased to progressively clear the remaining regions. The use of opposed inclined jets provides for rapid establishment of the operating mode, or of clearing a flooded plate, where the plate has closely spaced orifices.
