Abstract: An enclosed booth is provided with a low pressure, high volume air pump that outputs a stream of air for sandblast cleaning. A venturi nozzle having a venturi restriction at the end is positioned at the distal end of a first flexible tube. A second flexible tube has an outlet positioned adjacent to the venturi restriction which therefore creates a vacuum to pull sand media from the reservoir into the airflow and eject it out of the outlet nozzle of the first hose. This provides a low pressure stream of sandblast media for cleaning various parts. A reservoir is positioned at the bottom of the booth which is filled with the sandblast media. After the sandblasting media is output from the outlet nozzle, it falls through a substrate having apertures therein and enters the reservoir again.

Abstract: A method and device to prevent the refill of cartridges, including inject and laser printer cartridges. The device includes a cage made of hardened drill resistant material inserted within the central reservoir of the cartridge to prevent drilling into the cartridge. The device also includes a bit grabbing mesh designed to grab or catch any drill bit able to penetrate the drill resistant cage, thus impeding the ability of a refiller to drill holes into the central reservoir. The device also includes at least two pressure sensitive check valves that close if a refiller attempts to introduce refill ink either by forcing it in under pressure or by drawing it in by means of a vacuum created within the central reservoir. Finally, the device includes a number of packets containing an ink altering material that would be released and foul any refill ink during an attempt to refill the cartridge.

Abstract: An electronic proximity switch employs two oscillators coupled through two electrical paths, one associated with an antenna serving as a proximity switch sensor. Absorption by an object near the antenna changes the coupling between the oscillators producing a dramatic phase shift that may be detected and used for switching purposes.
