A smokeless ashtray includes an ashtray that is formed with an ash receiving cavity and air passageway. The ashtray is supported by a housing having an upper portion which forms an air intake substantially adjacent to the ash receiving cavity, and a bottom portion which removably receives the ashtray. The bottom portion also includes a motor filter receiving space and is formed with an exhaust aperture. A motor is mounted within the motor filter receiving space with a fan being connected thereto such that the fan is located below the ashtray. The smokeless ashtray also includes an ashtray filter and/or a motor filter. The air passageway of the ashtray is configured to receive the ashtray filter while the motor filter receiving space within bottom portion of the housing is configured to receive the motor filter. The fan creates an air flow by drawing smoke-filled air into the air intake down through the air passageway and out through the exhaust aperture with at least one of the ashtray filter and the motor filter being located within the air flow to remove smoke and impurities therefrom.

Smokeless ashtray

A window mounted oscillating fan. The fan has two blower modules each having a motor, fan blade, and diffuser. The diffuser is fixed in a stationary position relative to its fan blade. The window fan oscillates by pivoting all blower modules simultaneously through a single motorized oscillation mechanism. The blower units may be arranged to discharge air in parallel, or alternatively, in different directions. The blower units pivot about an axis inclined from the vertical, so that oscillation has a vertical component as well as horizontal. In different embodiments, the fans operate in tandem, facing the same direction at all times, or oscillate in different directions, thereby diffusing incoming air. The window fan has an air filter, and manual and automatic controls including a touch sensitive on-off switch, a thermostatic on-off switch, and a speed selector.

In general, in one aspect, the invention features a fastener having two mating pieces. One of the mating has a rigid surface of thickness q, and a hole in the surface, the hole including a slot defined by two generally parallel edges separated by a distance r. The other mating piece has a base and a pair of wings held above the base to define two generally parallel channels spaced to accommodate the two parallel edges of the slot, the channels having a thickness greater than q, the span of the wings being greater than r.

Fastening

A wall or room partition mountable modular rail rack component mounting system. The system includes wall racks shaped for interlocking engagement with each other at their opposite ends and cross stiffener members for placement between the wall rails to hold them in rigid space apart relationship. The wall rails each having a shaped opening at one end and a mating element at the other end thereof. The shaped opening and the mating element interlock with each other. The dimensions and spacings of openings and elements on the wall rails and rail racks for mounting thereon provide for rail racks mounted in vertically aligned closely space relationship that gives uninterrupted rail rack placement.

Humidifier

A containment system for significantly reducing the emission of high frequency electromagnetic waves from a computer system into the external environment. The containment system includes the combination of two enclosures and a shielding assembly. One of the enclosures is associated with the high frequency components and the other with the low frequency components of the computer system. The shielding assembly is positioned between the two enclosures to prevent high frequency electromagnetic waves from passing from one chamber to the other over the connection between the two chambers.
