A passage is provided between the housing and the outlet through which air can flow when a patient inhales through the outlet, A valve is located in the passage.   The valve is biassed so as normally to be in the open condition but will close automatically when the rate of flow of air inhaled by the patient exceeds a pre-determined amount. The valve is conveniently n hinged flap which is spring-loaded towards the open position.

Abstract: ABSTRACT OF THE DISCLOSURE      A multiple cartridge filter assembly is pro-vided with a removable filter array to facilitate the rapid replacement of an entire array having spent cartridges with another identical array having fresh cartridges, after which the spent cartridges of the removed array may be replaced.  The removable filter array includes a separation plate from which the filter cartridges hang suspended in sealing engage-ment therewith and a dual position support platform connected to the separation plate and located be-neath the lower blind ends of the cartridges.  The support platform maintains the cartridges sealingly engaged with the separation plate when the removable array is in its working condition but automatically drops down relative to the separation plate when the array is removed to accommodate the replacement of the cartridges.  In the preferred practice of the in-vention the movement of the support platform rela-tive to the separation plate is limited to that which permits removal of the filter cartridges at an angle but not vertically.

Abstract: FLOW RATE CONTROLLER          ABSTRACT         Flow control of a shear-sensitive, i.e. pressure gradient degradable, liquid from a high pressure source to a lower pressure discharge is achieved by controlling the liquid's exposure to a degradation pressure gradient.  Two displacement chambers are provided and connected by a control conduit.  First and second movable barrier means in the first and second chambers respectively contain a separate controlling liquid.  A pressure and flow control valve is included in the control conduit.  Incoming pressurized control-led shear-sensitive liquid flows into the first displacement chamber to displace the first barrier means which displaces controlling liquid through the flow control valve.  Shear-sensitive liquid is dispensed at relatively lower pressure from the second chamber in response to movement of the second barrier means driven by the controlling fluid coming from the control conduit into the second chamber.  The flow of controlled liquid to and from the chambers is selectively reversed to provide for continuous pumping from the high pressure source to the low pressure discharge. Indication of total flow and rate of flow of the controlled liquid through the discharge conduit may also be indicated.  The flow control valve is adjusted to establish the pressure drop imposed on the controlling liquid and thereby the pressure drop in the controlled liquid without subjecting the control-led fluid to a degradation pressure gradient.

Abstract: COAL DESULFURIZATION                       ABSTRACT       A substantial portion of the pyritic, organic, and sulfate sulfur compounds of coal are removed by a chemical cleaning process.  The coal is crushed to a particle size smaller than about 1/8 inch, slurried, and passed into a treatment container.  Alkaline solution is continuously introduced into the container so that there is a cross-wise flow of alkaline solution and slurry, and the spent alkaline solution is screened from the container and passed to a chemical recovery station.  The temperature and pressure conditions in the container are maintained to act with the alkaline solution to effect removal of the sulfur components of the coal.  The treated slurry is continuously washed to produce the final coal, the slurry having a consistency of about 40-70 percent throughout.

Abstract: ABSTRACT OF THE DISCLOSURE           The present brake actuator is inserted between the brake master cylinder and the usual power booster in an automotive vehicle braking system.  It includes a cylinder for bolt-on attachment to the master cylinder housing and the booster housing.  A piston in the actuator is on a shaft positioned end-to-end between the shaft in the booster, which is operated by the brake pedal, and the piston rod of the master cylinder.  This permits normal braking under the control of the brake pedal.  A solenoid valve mounted on the actuator housing applies either atmospheric pressure or vacuum from the engine intake manifold to the interior of the actuator on one side of the piston.  When vacuum is applied, the actuator piston moves in a direction to apply the brakes irrespective of the brake pedal.  This happens in response to a predetermined event, such as the driver leaving the driver's seat of the vehicle.

The  noise-level warning threshold assumes a fixed relation to the operating or working point level of the signal transmitted by the detector of the alarm system while taking into account consideration shifts in the level of the operating or working point. An alarm storage or buffer disposed in the detector is set without transmitting an alarm signal when the noise-level warning threshold has been exceeded.  The noise-level is monitored during normal operation and gives sufficiently early warning of a tendency to generate false alarms.
