A particulate trap has a housing and a plurality of filters disposed within the housing. The particulate trap also has a plurality of dividers fluidly isolating one or more of the plurality of filters into filter divisions. The particulate trap has at least one inlet and at least one outlet individually associated with each filter division, and a valve assembly configured to selectively block a flow of exhaust air through each of the inlets.

The invention comprises a trap (1), adapted for small animals, generally shaped as a tunnel part (A), where one end area (1) of the tunnel part is shaped and adapted to a space (B), intended for a bait (100), where this space (B), in a direction with the tunnel and towards its other end area (A2), is demarcated by one or several mechanism-releasing means, such as threads (31), and where an open snare (32) is oriented, in any case close to the floor and wall sections of the tunnel, and positioned...

A particulate trap has a plurality of filters and an air distributor. The air distributor has an inner tube and an outer tube. Each of the inner and outer tubes have a plurality of openings to allow exhaust flow to the plurality of filters. One of the inner and outer tubes is rotatable to selectively block exhaust flow to at least one of the plurality of filters at a given time.

A waste trap 10 for use in plumbing installations is provided, the trap comprising a unitary metal body 12 defining an interior volume, and having a tubular plastics insert 20 located in an inlet 14 of the body 12 and extending into the volume to below the height of a waste outlet 16. The insert 20 partitions the upper portion of the volume into two regions, and serves to provide a water seal between the inlet 14 and the outlet 16 when the trap is in use. The insert is non-removably secured to t...

A lobster trap having at least two lobster feeding chambers separated from one another with no direct or indirect access from one lobster feeding chamber to the other(s), each lobster feeding chamber having a lobster trap head to the exterior of the lobster trap and a centrally disposed bait well accessible to each lobster feeding chamber, such lobster trap characterized by the lack of a parlor chamber.

A mole trap has a pair of spring-loaded jaws. A platform is pivotally connected to the jaws to limit the travel of the trap into the ground and to stabilize the trap on the ground when it is set. A lever assembly forces the jaws open and sets the trap. An adjustable trigger mechanism is positioned on the ground above a mole burrow. The disturbance of a mole traveling beneath the trigger causes the lever assembly to collapse, thereby permitting the jaws to close and destroy the animal.

A trap apparatus includes a discharge path for evacuating a hermetically sealed chamber through a vacuum pump, a hermetically sealed trap container extended across the discharge path and a regeneration path disposed adjacent to the discharge path, a trap unit disposed in the trap container for attaching a product in a discharged gas thereon and removing the product form the discharged gas, the trap unit being selectively located at the discharge path or the regeneration path, a valve element dis...

An insect trap (10) is operable in either an electrocuting mode or non-electrocuting mode. Further, an integral grid tester (96) is used to test whether or not power is being supplied to the grid (40).

An apparatus for simulating a blackbody utilizes several plates to absorb and reflect electromagnetic radiation. Electromagnetic radiation entering the apparatus from a certain view is reflected from one plate to another, until the direction of travel of the electromagnetic radiation is reversed. Each time the electromagnetic radiation is reflected, the majority of the electromagnetic radiation is absorbed resulting in a negligible amount of incoming electromagnetic radiation escaping the appara...

A water trap comprising a cylindrical outer casing having a flat top wall and a frustoconical bottom wall, an internal substantially semi-circular open topped water seal container within the outer casing, an inlet into the water seal container which passes through the top wall and abuts one side wall of the water seal container and extends thereinto, and an outlet from the bottom wall of the trap that is offset from, and co-linear with, the inlet. The cross-sectional areas within the trap progre...
