Abstract: The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides a heating member that can be formed of a heating element conformed to a heater substrate configured as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size. In some embodiments, the disclosure provides methods of forming an aerosol delivery device, which can include providing a shell, providing a heating member formed of a heating element conformed to a substrate, configuring the heating member as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size, and inserting the heating member within the shell.

Abstract: A support appliance is provided with a base structure comprising a plurality of hinged base boards arranged to be mounted on a standard hospital bed and providing a continuous, firm, base underlying a plurality of inflatable patient supporting air sacs to which air is supplied from headers supported by said base structure which headers are individually supplied with air under pressure by flexible conduits releasably connected to pressurized air supply conduits in a single housing connected at an edge of said base structure.

Abstract: A mattress is provided having a body which incorporates a plurality of air supply chambers which are connected to air supply conduits, a plurality of inflatable air sacs being mounted on the mattress for supporting a person thereon and being connected to ports in the chambers so that air can be supplied to the air sacs via the conduits and supply chambers.

Abstract: A method of measuring the containment efficiency of a biological safety cabinet comprises releasing an aerosol of identifiable droplets within the cabinet and then sampling ambient air in the proximity of the cabinet so as to determine if particles of said droplets have escaped from the cabinet. Apparatus for producing a suitable aerosol comprises an impeller rotatable about an upright axis, an electric motor for rotating the impeller at high speed, (e.g. 20,000 to 30,000 r.p.m.), a reservoir for potassium iodide aerosol solution disposed above the impeller, and a hypodermic needle for providing a controlled flow of aerosol solution from the reservoir to the impeller, whereby rotation of the impeller disperses particles of the aerosol solution.
