Bucket-type cutters

The bucket-type cutters have the advantage of being able to collect and transport the sample laterally, without the loss of headroom they collect and hold the sample, however, and thus allow material build-up within the bucket if the powder is a little sticky. Another disadvantage is that, whilst the mass of the diverter-type cutter remains the same during its traverse across the falling stream, the mass of the bucket cutter increases rapidly and the drive systems must be powerful enough to maintain its speed. 

The cutters in use in mechanical sampling are divided into diverter types and bucket types. Both types are used to cut a stream falling due to gravity off the end of a conveyor belt or from the discharge end of a pneumatic conveying pipe or a chute. 

Spatial or area repellents are designed to repel and kill biting arthropods in relatively small, semienclosed areas. These prodncts are generally formulated as candles, coils, or prodncts with some type (often bntane) of catalytic converter to burn and passively dispense the active ingredient. These prodncts often contain either essential oils, such as oil of citronella, or allethrin as the active ingredient. Commonly available products include Cutter Area Repellent Holiday Bucket Candle and Trip Wick citronella candle (United Industries), OFF PowerPad lamp and lantern, OFF Yard and Deck Area Repellent II, OFF Mosquito Coil III, OFF citronella...
