A bubble trap having a cylindrically symmetrical chamber, a filter covering an outlet and offset from the axis of the chamber, an inlet with a plurality of vertically aligned orifices, the orifices arranged to produce circumferential flow within the chamber. Bubbles in the liquid coalesce on the filter and are removed. A method of removing bubbles is also disclosed.

A mouse trap includes: a main body including a top plate and right and left side plates, of resilient material and suspended downwardly from opposite ends of the top plate, to be oppositely closed by their own resiliency, for holding and capturing a mouse therebetween; a bottom plate pivoted at one end to the lower end of one of the side plates; a stopper having a pair of engagement projections fixed to the other end of the bottom plate at its upper surface; an engagement releasing lever pivoted...

An improved trap for a mouse of the type having a baseboard, a U-shaped jaw member that is pivotally mounted on the baseboard for pivotal movement from a cocked position to a sprung position, a bait pedal that is attached to the baseboard, and a trigger mechanism that has a longitudinal axis and which is operatively attached to the bait pedal and when the U-shaped jaw member is in the cocked position thereof the trigger mechanism is operatively connected to the U-shaped jaw member. The improveme...

A trap for receiving and holding bullets and fragments thereof. A funnel shaped receiver is mounted atop a frame and has a narrow exit connected to a collector tube arranged at an acute angle relative to the longitudinal axis of the receiver. The collector tube empties into a circular chamber of an offset housing dissipating the kinetic energy of the bullet.

An animal trap includes a housing having a bottom wall, side walls, a top wall and a front opening in the side walls, opposing slots in the side walls adjacent the opening, and opposing channels in the side walls immediately behind the slots; a door slidably mounted in the slots for movement between raised and lowered positions to unblock and block the opening; a platform pivotally positioned on the bottom wall; levers pivotally mounted to the side walls adjacent the opening, each having a front...

A cockroach trap includes an open-topped base and a cover pivotally connected to the base. The base is provided on sidewalls with a plurality of entrances closed with inward openable one-way trapdoors, and on a bottom with a bait compartment and two multipolar metal conductors that provide alternately arranged positive and negative poles. The cover is provided on a top with an AC/DC control circuit, an output of which is connected to the two metal conductors. A periodic/manual discharge selector...

A continuous processing trap apparatus is capable of increasing the trapping efficiency while maintaining conductance required by a vacuum chamber. The trap apparatus includes an exhaust passage for evacuating a hermetically sealed chamber by a vacuum pump, a hermetically sealed trapping and regenerating casing extending across the exhaust passage and a regenerating passage adjacent to the exhaust passage, and a trap unit movably housed in the trapping and regenerating casing for selective movem...

Methods and apparatus implementing a technique for forming a trap polygon which does not interfere with the print quality of other trap polygons or objects. Edges in close proximity to a color transition edge ("CTE") are checked for potential interference. A trap polygon is formed for the CTE that avoids any interfering edges or trap polygons for those edges. The technique can be applied to form a trap polygon for each edge in a page to be printed. In general, in one aspect, forming a trap polyg...

A mosquito trap, capable of trapping and killing a very high percentage of mosquitoes by attracting and killing mosquitoes simply, safely and effectively. The trap utilizes the attractant lactic acid applied to easily replaceable adhesive panels located inside the trap. A mesh screen located outside of the treated panels and having particular sized openings, allows only mosquitoes and smaller insects to fly into the mosquito trap and prevents contact with the adhesive panels from outside sources...

A blood-feeding-fly trap composed of 3 or more legs held in position by a top element or elements and a flexible cover. Spacing rods also locate the legs and hold the cover taut. A dark object hangs freely from the top element to attract the flies which are retained in a container at the top of the trap. The design allows easy relocation when assembled. All major elements are held by fasteners that allow assembly and disassembly for efficient manufacture, shipping, and storage.
