Abstract: An aerosol generator (10) includes a plate (18) defining an orifice (20) through which a jet of liquid is projected, which breaks up into droplets. The plate (18) is vibrated to control the droplet size, and the size distribution. The droplet size distribution is monitored, and this information is used to control the vibration to ensure the droplets are monodisperse and of the correct size. This can be achieved as follows: the droplets are diverted by a transverse air stream, and an optical image is obtained of the diverted jet (28) onto a linear array of photodetectors (34). The signals from the photodetectors represent the particle size distribution, and are supplied as input to a computer (36) whose output is used to control the vibration of the plate (18).

Abstract: A method and apparatus for proportional sampling of particulate material present in the exhaust gas emitted from an engine, in order to measure the mass of particulate material present in the exhaust gas, utilizes a mixing chamber (18) for mixing a portion of the exhaust gas with a dilution gas. A flow control (20) controls the flow rate of the portion of the exhaust gas as a function of exhaust gas flow by activating individual ones of a parallel array of solenoid valves (30), each defining a flow restriction (34).

Abstract: An aerosol sampler comprises at least one U-tube whose ends are fixed to a support, and through which the aerosol is caused to flow. Means are provided to set the tube vibrating, and to measure its resonant frequency. The bend of the U-tube acts as an impactor so aerosol particles larger than a cut-off size are trapped, causing a change in the measured frequency. A sampler may include a number of such U-tubes in series, with steadily decreasing cut-off sizes, so the aerosol particulate size distribution can be determined.

Abstract: An enclosure for a pocket calculator can be mounted on the user's forearm or mounted at a 45.degree. angle to a desktop. This dual positioning of the calculator is achieved by a pad positioned between the enclosure and the user's forearm when the enclosure is mounted on the forearm. When it is desired to mount the calculator on a desktop, the pad may be partly folded to form a prop for propping the upper side of the calculator above the desktop. The enclosure has a transparent window above the keys of the calculator made of a plastic vinyl material so highly flexible that the user can depress any selected key with his finger without depressing any other key.
